Counterfeit medicine, also known as fake medicine, is a medication or pharmaceutical product that is produced and sold with the intent to deceive. It may look like a legitimate brand-name product. However, it contains incorrect, insufficient, or harmful ingredients. Counterfeit medicines pose a serious threat to public health. It can be ineffective, cause adverse side effects, or even lead to death. Traditional methods for detecting fake medicines involve visual inspection of packaging for inconsistencies like misspellings, poor print quality, checking the pill's appearance, color, and size for anomalies, and verifying the expiration date. That means more or less traditional methods were subjective and prone to human error. One separate technique could be analyzing the chemical composition of medicines. It was time-consuming and expensive Therefore, it never became viable solution. Furthermore, counterfeiters are becoming increasingly sophisticated with the advent of internet that makes it difficult to distinguish fake medicines from genuine ones using conventional techniques. Reinforcement learning can be a powerful tool in detecting counterfeit medicines. Reinforcement learning is a type of machine learning where an agent learns to make decisions by interacting with an environment and receiving rewards or penalties for its actions. By training an AI agent to analyze various features like packaging, labeling, and chemical composition, it can learn to distinguish between genuine and fake products. Through iterative learning and reward-based feedback, the AI agent can continuously improve its accuracy in identifying counterfeit medicines. This technology can help automate the detection process, making it more efficient and reliable than traditional methods. Additionally, it can be used to develop real-time detection systems that can alert authorities and consumers about counterfeit products in circulation. Reinforcement learning's adaptability and ability to learn from continuous feedback makes it well-suited for detecting counterfeit medicines, as it can adapt to evolving counterfeit techniques and improve its accuracy over time.

Packaging has become an indispensable part of our daily lives, without which it would bring great inconvenience and insecurity to consumers. The current global trend is to reduce the amount of packaging waste by recycling the same materials or using renewable waste raw materials. After each year's corn harvest, a large amount of straw is discarded in fields, and these corn straws are becoming an alternative source for wood fibers in green packaging. This study evaluates the feasibility of using straw fibers for gravure printing packaging by observing the quality parameters of gravure printing and the ink penetration into the printing substrate. From the experimental results, it can be seen that the gravure printing ink penetrates too much into the printing substrate, resulting in uneven surface ink distribution. The viscosity of the ink and the printing process itself have a significant impact on this. Therefore, gravure printing needs to add additional coatings or more fillers in the paper structure to improve it.

A numerical study is performed to enhance the performance of electric vehicle batteries of different shapes using different cooling methods. Three cooling approaches were examined: no cooling, water cooling, and the incorporation of nanoparticles in the cooling plate with considering variety of batteries. There are five different setups made for analysis with and without considering flow channels for single and pack up batteries. When the battery pack operated without any cooling mechanism, the maximum temperature (T_max) reached approximately 367 K. This finding underscores the inherent thermal challenges associated with uncooled battery systems, as elevated temperatures can lead to reduced efficiency and accelerated degradation. Implementing a water-cooling system resulted in a notable improvement in thermal performance. The T_max observed with water cooling was reduced around 354 K. The circulating water effectively dissipated heat from the battery pack, mitigating temperature spikes and enhancing overall thermal stability. The introduction of copper oxide (CuO) nanoparticles into the cooling plate demonstrated the most significant impact on thermal management. The T_max recorded with CuO nanoparticles cooling was substantially lower, measuring around 337 K. The findings of this study have significant implications for the design and optimization of cooling systems for the different battery packs. Efficient thermal management, as demonstrated by water cooling and CuO nanoparticles cooling, can extend the lifespan of batteries, improve overall performance, and contribute to the safety of energy storage systems.

As an effective way of large-scale consumption of renewable energy for power generation, off grid hydrogen production and ammonia synthesis systems face multiple challenges in terms of stability and economic operation. The key is how to reasonably allocate the number of electrolytic cells and ammonia load to ensure stable operation of the system throughout the year. In response to these technical difficulties, this article constructs an 8760 hours renewable energy electric hydrogen synthesis ammonia production simulation model that comprehensively considers the abandonment rate and load stability. A reasonable operation planning method for the number of electrolytic cell startups and ammonia load has been proposed. On the premise of ensuring compliance with system constraints, the model can dynamically adjust the number of start-up units, optimize ammonia load, and achieve efficient utilization of wind and solar resources. To verify the actual effectiveness of this method, this article selects a specific case study from Da'an District, Jilin Province for analysis. The results indicate that the planning method proposed in this article not only successfully simulated the production process of ammonia through electric hydrogen synthesis based on 8760 hours of off grid renewable energy, but also significantly improved the rationality of the off-grid system.

The transformative implications of Information and Communication Technology (ICT) on the teaching and learning fraternity has necessitated its integration in the classroom, globally. Nevertheless, it is important to note that the quest for integration in individual school contexts remains an uphill task despite ICT integration being a policy prerogative in a number of countries. This survey has the sole objective of unpacking how the teaching and learning process has been affected due to lack of ICT resources. By use of a simple questionnaire, the researcher made use of semi-structured interviews in order to solicit data from educators in selected South African primary schools. The interviews were transcribed manually and coded. The data analysis process was conducted by use of a thematic mode of analysis. The findings demonstrated that, due to several reasons, many schools do not make use of ICT tools in teaching and learning, as expected, and in most cases, they do not maximise the use of the existing resources, thus affecting the teaching and learning processes. The reasearcher recommends that the South African Department of Basic Education (DBE) seriously take into consideration individual school contexts when allocating ICT resources in order to try and mitigate the challenges. Stepping up monitoring and evaluation mechanisms that currently exist will help identify contextual challenges and help with providing assistance where necessary. Security issues also call for schools to team up with local communities to try and fight the theft and vandalisation of IT resources. All these measures are meant to facilitate the preservation and use of ICT resources in the classroom for the improvement of the learning process.

In the fast-paced landscape of contemporary education, Science, Technology, Engineering, Arts, and Mathematics (STEAM) education stands as a vanguard aimed at equipping students with the skills required for the 21st century. Science, Technology, Engineering and Mathematics (STEM) alone has proven to miss several components that are critical for children and students to thrive in the 21^st century economy, in terms of application, creation, innovation and ingenuity. As such, STEAM can complete the package of benefits to students by integrating arts principles, which allows them to connect their learning to wonder, critique, inquiry, and innovation. While STEAM education is increasingly recognized as a crucial educational approach, the precise role of research within it and how it can be effectively formalized remains a topic of inquiry. In recent years, there have been emerging methodologies that integrate STEAM in education, and which offer pedagogical alternatives that are more holistic and attractive, and which offer prospects to formalize research in science education. This qualitative systematic review embarks on an exploration of the pivotal role of reading and research within STEAM education, addressing the need to formalize innovation in science education. Data for this systematic review have been sourced from peer-reviewed journal articles, conference papers, and reports that focus on qualitative research within STEM and STEAM education.

A few network security communities of security practitioners, researchers, hackers, attackers etc. frequently use Black-Listed IP addresses; they also use them as target IP addresses for exercising various network attacks while learning and practicing hacking or security analysis. These IP addresses may be in previous few occasions black-listed or blocked; if not, they may get eventually be black-listed too. A few ISPs in developing and least developing countries purchase such black-listed or blocked IP addresses (BLIP) in much cheaper price and distribute to their Internet users.

There are risks of using BLIPs as the community of white-hat and black-hat hackers, intentionally or being unknown that the IP addresses they have been using no longer belong to them, may still be using them as the target as usual. Thus, the Internet clients using BLIPs (assigned by their ISPs) may be victimized of various attacks without knowing that their computers and network devices have been assigned with bad IP addresses. There are professional and legal issues too in addition to the issue of business ethics and they must be addressed in a proper manner. Here, in this editorial, I am proposing network security approaches to mitigate risks occurring in using such addresses. The ISPs can implement these approaches while the issues are being resolved.

During the intense pandemic, a new and initially unpopular concept emerged: working from home. As everyone was forced to stay inside, businesses couldn't come to a halt. So, a new way of working was introduced: setting up virtual offices at home, allowing employees to work and communicate with colleagues online. Although the traditional office environment was missing, many companies found that employees' productivity increased significantly.

Interestingly, after the pandemic, many companies introduced a hybrid working model. This approach allowed employees to choose where they wanted to work based on their mood and preferences. I acknowledge the boost in productivity, but it came with its own set of challenges. Creating a suitable work environment at home was difficult. Background noises, such as family disputes, often disrupted virtual meetings. Additionally, internet issues were widespread as everyone was using the internet at home. In India, technical advancements were limited, making it challenging to solve these problems. Despite these hurdles, employees managed to adapt, stabilizing the industry.

Antenna designers are constantly challenged with the temptation to search for optimum solutions for complex Electromagnetic device designs. The ever- increasing advances in computational power have fuelled this temptation. The well-known brute force design methodologies are systematically being replaced by the state-of-the-art optimization techniques. The ability of using numerical methods to accurately and efficiently characterize the relative quality of a particular design has excited the EM engineers to apply stochastic global Evolutionary optimizers (EO). The EO techniques have been applied with growing applications to the design of Electromagnetic systems of increasing complexity. The recent popularity experienced by EO methods is not unique to the field of Electromagnetics. Among various EO techniques, the Improved particle swarm optimization (IPSO) has attracted considerable attention. These schemes are finding popularity within Electromagnetic community as design tools and problem solvers because of their versatility and ability to optimize in complex multimodal search spaces applied to non-differentiable cost functions. The overall radiation pattern of the antenna array can be shaped by the structure of the array, distance between the elements and its amplitude and phase excitations. Synthesis of linear arrays have been extensively studied from the past decades. Applied to linear antenna array optimization to optimize the excitation weights and element positions for better side lobe level reduction and advanced null control have been studied. IPSO has been used to non-uniformly optimize the element positions to produce a minimum side lobe level with no back lobes pattern of the linear antenna array. The design of linear array for applications in Wi-Max (World wide Interoperability for Microwave access) base stations for improved signal to interference ratio, lower cost, resistance to multipath and fading, improved co-channel Interference, enhanced frequency reuse, improved spectral efficiency and space-time diversity for MIMO channels in Wireless communications is a burning topic of discussion nowadays in the Electromagnetic Community.

The effects of multiple earthquakes of different frequency content on the global response of steel building are presented in this paper. Multiple earthquakes forming sequences as mainshock-aftershock pairs, three (3) steel moment resisting frames of 10-storey (H10), 15-storey (H15) and 20-storey (H20) were analyzed according to the code provisions of IS 1893 (Part 1): 2016 using sequential nonlinear response history analyses. The frequency content of mainshock and aftershock records were varied based on the PGA/PGV ratio. The result produced expected differences in structural responses conditional on the frequency content and the dynamic characteristics of each model. The outcome is measurable differences in the structural response, with the inter-storey drift and other structural response parameters changing due to the different frequency characteristics of the aftershocks. It is expected that the conclusions drawn in this paper will lead to an improvement of the IS 1893 with regards to multiple earthquake effect for an improved design and construction of steel frame structures in India, which will lead to better seismic performance.

The X-ray is a fantastic invention that has found widespread use in the medical area and as a metal detector, among other things. However, because the conventional X-ray generating technique requires a high voltage of several kilovolts, it is expensive. Here, we've presented a reliable technique that makes use of quantum technology to produce X-rays with just a few volts. In addition, we have implemented an X-ray method for the identification of lung and breast cancer. The next step is precisely positioning gold nanowires for tailored drug delivery. The interaction of light with metal nanoparticles has been studied for a very long time, both theoretically and experimentally. Silver and gold nanoparticles, which usually have sizes between 5 and 150 nm, are very interesting because they have the ability to modify their binding affinity. This means that the formulation of the nanoparticles may be perfectly matched to a particular type of cancer by excitation with the resonance of the generated X-ray spectrum range. On the other hand, when these particles are arranged as grating elements in a gold nanowire network structure (AuNW), several interesting occurrences take place.

A proto-persona, which represents a target audience or user segment, is an initial or rudimentary iteration of a persona. It is a conceptual frame-work that encompasses fundamental attributes, actions, requirements, and aspirations of a cohort of users. Proto-personas are typically created early in the product development process, often based on assumptions, prior knowledge, or limited research. The limitations of the participant who creates the proto persona can compromise the quality and effectiveness of the personas, leading to decisions that are not well-informed or aligned with the needs of the users. Biases, limited perspective, incomplete information, skill level, limited resources, and communication challenges can compromise the quality of proto personas, leading to inaccurate representations of the target audience. The use of Artificial Intelligence (AI) can help improve the quality of proto-persona as well can expedite the creation process by analyzing the vast amounts of data to provide comprehensive demographic details, mitigating biases and enriching proto persona creation with di-verse insights, thus enhancing the accuracy and inclusivity of the personas. The paper provides an insight into the real-world experiment of proto-persona creation using OpenAI tuned-model.

Co-operatives have proved to be one of the driving forces in the socio-economic empowerment of its members. The Government of Tanzania has been implementing the Poverty Reduction Strategy by encouraging people to form co-operatives in order to improve their economic prospects. Establishing a primary co-operative society involves a process which passes through district co-operative office, regional co-operative office and the registrar of co-operatives’ office at the national level. These processes bring about the issue of documentation and records keeping. The processing of records is done manually by using pen and papers, or electronically using computers, smart phones and cameras. The research work essentially used questionnaire, interview, observation and document review to gather data. Findings of this study show that 8 out of 13 respondents (61.5%) responded to physically visit co-operative offices to acquire existing records about co-operative societies. This vividly explains use of manual procedure for co-operative records management thus leading to unsolved challenges such as; data inaccuracy and inconsistency, bureaucracy during physical access, money and time consumption due to geographical challenges, lack of transparence, and improper presentation of co-operative information in request. This ongoing research work proposes a web-mobile approach named Co-operative Records Management System (CRMS). CRMS will offer a solution which enable District Co-operative officers (DCOs) to record, process and generate electronic reports on co-operative societies’ records thus mitigating challenges about, but not limited to; time wastage, inconsistency in recording financial records as well as reducing costs for data acquisition. Therefore, this paper explores methods to enhance co-operative records management through web-mobile solutions, as evidenced in the Kilimanjaro region, and presents a proposed design solution.

     In the ever-evolving world of software development and cloud computing, multi-tenant systems have emerged as a fundamental architecture for delivering scalable, cost-effective, and flexible solutions. These systems, which allow multiple users or organisations to share the same computing resources while maintaining data isolation and privacy, are at the heart of many Software as a Service (SaaS) platforms and cloud applications.

     At its core, a multi-tenant system allows different tenants; individuals or organisations, to access a single instance of a software application, with each tenant's data isolated from others. This design contrasts with single-tenant systems, where each customer has their own dedicated instance. By leveraging shared infrastructure, multi-tenancy provides significant advantages in terms of resource utilisation and cost efficiency. This architecture not only reduces the overhead associated with maintaining multiple instances but also optimises the use of available resources, making it a preferred choice for many service providers.

     Large language models (LLMs) are revolutionizing the way we interact with information. But these powerful tools do not operate in a vacuum. We need instructions to guide LLMs towards the desired outcome. This is where prompt engineering comes in. LLMs are trained on massive datasets of text and code. While this imbues them with vast knowledge, it doesn't guarantee they will understand our specific requests. A poorly written request can send the LLM into a rabbit hole, resulting in meaningless or irrelevant text.

     Prompt engineering is a technique in artificial intelligence (AI) that optimizes and fine-tunes language models for specific activities and intended outcomes. Also known as prompt design, it is the act of carefully creating prompts or inputs for AI models in order to improve their performance on specific tasks. Prompts are used to instruct and fine-tune the AI system's desired behaviour, as well as to acquire accurate and desirable responses from AI models. Generative AI systems, powered by transformer architectures, are designed to produce specific outputs based on the quality of provided prompts. Prompt engineering ensures that these AI models comprehend and respond effectively to a wide range of queries, from simple to highly technical. The fundamental rule is simple: good prompts yield good results.

Aluminum alloys have received wide attention in the field of industry in recent times due to their lightweight, high resistance to corrosion, and ease of formation. In addition to their availability and affordability, the problems that occur in the welding of aluminum by traditional methods make the friction stir welding process one of the most important welding processes. This solid-state welding process was discovered in 1991 by TUW and is widely used in the welding of dissimilar aluminum alloys. In our research, we welded two important aluminum alloys in the industry (A7075/AA6061) with a thickness of 3mm. We changed some welding process parameters, including tool pin length, feed rate, and rotational speed. After placing an alloy (AA 6061) in the advanced side and tilting the tool, we examined the welded samples to find out the effect of the aforementioned parameters on the tensile strength and resulting hardness. We found that the length of the tool pin has the greatest influence on these properties, as they increase with the increase in the length of the pin. We also noted that the rotation speed and feed rate have a joint effect on the mechanical properties. The highest hardness was obtained at feed rates of 20 and 45 mm/min and rotational speeds of 1200 and 900 rpm, respectively. The highest tensile strength of 209 Mpa was obtained at a rotation speed of 1200 rpm and a feed rate of 20 mm/min.

Chemical-enhanced oil recovery (EOR) represents a pivotal technology in the petroleum industry, aimed at maximizing the extraction of hydrocarbons from reservoirs. Traditional oil recovery methods typically leave a substantial portion of the oil in the reservoir, making EOR techniques crucial for boosting extraction efficiency. Among the various chemical EOR methods, polymer flooding stands out due to its ability to improve the viscosity of the displacing fluid, thus enhancing the sweep efficiency and reducing the mobility ratio. This manuscript explores the application of polymeric composites in chemical EOR, highlighting their formulation, mechanisms, advantages, challenges, and recent advancements

Civil Engineers encounter serious problems when dealing with structures (buildings, roads, dams, etc.) built on gypsiferous soil or near-surface gypsum beds. However, gypsum (CaS0₄.2H₂O) in soil with small quantities is beneficial for plants, due to its soluble properties in the water. So it has two impacts on our lives; negative and positive. This article sheds some light on the economic impact of soil with high gypsum content. Such soil is distributed worldwide and some examples from Iraq are presented afterwards.

Hacking used to be linked with computer enthusiasts making positive improvements. But now, it has split into two sides: ethical and unethical practices. Originating from MIT's hacker culture, the paper examines the mindset, motivations, and influences behind the transition of hackers, in unauthorized and harmful activities, known as "black hat" hacking. Hackers, initially driven by a dream to enhance human life through computers, became divided into black hats and white hats, separated by a fuzzy gray line. While both possess technical expertise, black hats engage in bad activities driven by motivations such as financial gain, revenge, ideology, curiosity, ego, and enjoyment. Money and ego emerge as primary influencers leading hackers towards the black hat path. The study emphasizes the interplay of technical skills, human vulnerabilities, and hacking methods. Despite the negative impact, black hat activities unintentionally contribute to technological progress. The paper concludes by highlighting the importance of understanding the human aspect of hacking in the evolving digital landscape.

In today's world, sustainability has become a paramount goal for addressing pressing environmental, social, and economic challenges. Engineers play a crucial role in this endeavor, as they possess the expertise and innovative mindset needed to develop sustainable solutions that promote the well-being of both present and future generations. From renewable energy systems to eco-friendly infrastructure, engineers are at the forefront of designing and implementing initiatives that contribute to a more sustainable and resilient world.

‘Green’ aptly means the eco-friendly sustainability and socio-ecological performance. Over the years ever increasing and dominating industrialisation led to environmental degradation impacting global socio-economic order, climate change and natural imbalance. Strategic issues like carbon footprint, energy crisis have been seriously debated targeting mission ‘Go green’ for net zero adopting green technology, practices and processes in industry. Globally, with India no exception, sincere and dedicated efforts are in place for an alternative to existing technological and growth processes and practices towards clean and green environment for sustainable development, growth, prosperity and well-being.

With the progress of civilization there is an always exponential demand for raw material utilization to sustain the materialistic requirement of the human race. With passage of time man learnt to process raw materials to produce final products of desired size and shape as per utility to suffice the needs of life and daily activities. The process of conversion of the raw material to a finished product is always assisted with waste generation. Depending on the raw materials grade, process route entrusted for manufacturing and professional practice at the concerned industrial unit, waste generation also varies. With passage of time there is an ever-increasing thrust on demands for more materials for various applications leading to stress on raw materials, their supply and logistics support. Raw materials are either to be mined out from natural resources or sometimes need to be re-processed out from wastes. With demand of various materials for products, there is waste generation of multitude dimension in every front which itself is a challenge. Waste management thus becomes an uttermost importance since unscientific disposal of wastes creates lot of problems and stress on land. Generally, wastes are coming from any industrial and municipal activities are either solid, liquid and gaseous form. It is not necessary that wastes are all useless they also contain several important constituents for use. For example: Blast Furnace slag, Steel melting shop slag have utility in construction sector as well as for fertilizers. Process optimization in connection with waste generation is now becoming a strong trend since raw materials are not of unlimited supply. Natural resources are executing signs of constraints in various forms like interrupted supply, unavailability of proper grade leading to difficulty and stress on research development for product maturation with lean grade materials. Working with lean grade materials involves lots of more energy and process upgradation which cause waste generation. Without proper scientific approach of waste handling, landfill problem is becoming more acute along with environmental pollution, soil conditioning problem and others which possess further chain of critical challenges for sustainability of various human activities including availability of proper agricultural land and forest coverage. As per law of conservation of mass, materials are constant in the universe either created or destroyed maintaining an equilibrium. Disturbance of equilibrium may shift the balance in either direction which may cause catastrophic impact on sustainability. With more focus on green energy sector, alternative methods of energy generation are under need which also cause more shift on different material processing with exploitation on different natural resources. Wastes should be treated like another source for extraction materials for our needs since natural source may got exhausted just like in the case of hydrocarbon and coal reserves. Recycling of different items or wastes addition during any process already in practice is coming up with supports of proven research and development. It leads to reduction in raw material demand as well as saving of energy leading to reduction of energy consumption for product development. Any sort of energy generation is found to be directly liked with green house gas emission which could be reduced by such practice and adoption of new techniques. Directly it would also control excessive mining activities that is required from extraction of materials from earth sources. Mine reclamation is now days in practice after the mine got exhausted of the reserves for the required time period. Mine reclamation is noted to be useful to regenerate natural conditions like soil, vegetation and other factors which may help in distant future for sustainability and maintenance of ecological balance. Thus, in brief it could be noted with vital interest that waste re-engineering for better utility and source, recycling of products and mine reclamation is linked in a certain chain or cycle which actually reduce energy consumption, green house gas emission, maintaining balance of optimum utilization of natural resources thus paving the pathway for better future and sustainable approach.

In accordance with the latest national standard, the dynamic characterization of bridges and viaducts has become mandatory: a necessary action for newly constructed works in terms of dynamic testing and strongly recommended in the case of verification of existing structures. Based on the experience acquired for over fifteen years, we want to classify the construction types according to the actions to which they are subjected in relation to the possibility of carrying out an efficient operational analysis. In other words, to describe the optimal solutions according to the constructive characteristics; that is, if the excitation of the wind alone is better, or if it is preferable to have it combined with road or rail traffic that occurs nearby and how much it is preferable to stay on a motorway overpass, rather than on a road along-side, but not in continuity, with another in which traffic has not been interrupted. The work aims to evaluate the type of transducers most suitable for performing OMA on this type of structure. Having established that accelerometers, although less resolute than velocimeters, allow better phase stability, we will evaluate which of them that are the best in terms of performance-cost, especially in terms of spectral noise compared to the magnitude to be measured. The potential and limitations of wireless solutions are also analyzed and compared with traditional wired ones.

Paramagnetic complexes of transition metals and rare earths have attracted a lot of interest in the last year in medical imaging. Indeed, the study by ¹H NMR spectroscopy has revealed that these agents increase the contrast between an affected cell and a normal one in biological tissues. This increase in contrast is due to the decrease in the nuclear relaxation time of the ¹H proton of water. Due to their high magnetic moment, the dipolar interactions between these agents and water molecules are strong, which mainly reduces the nuclear relaxation time of ¹H protons. Bloch was the first to use ferric nitrate as an agent of observation.

One of the important factors for dry blend processes of Suspension Polyvinyl Chloride resin is porosity.

Many parameters have direct and indirect impacts on it.

Direct parameters are operationally controlled and related to the selection of a secondary emulsifier, know as a porisifier.

This parameter is controlled by Reaction Recipe parameters, including agitation intensity, emulsifier ratios, catalyst type, polymerizer temperature, conversion rate, interfacial tension, and PVA degree of polymerization.

On the other hand, the indirect parameters are related to system impurity levels in the reactor. Such impurities are originated from two main sources: namely, Vinyl Chloride monomer, (VCM), and charging water quality.

The application of Nano-Buffer materials in the polymerization phase has revealed the economical improvement of resin porosity.

The results have shown porosity improvements in some applications of around 7%, resulting in operating costs reduction of about 15% in some applications.

     Heap is a topic of interest among security researchers and exploit developers who are looking for vulnerabilities in modern-day software. The complexity of allocators like the one used by GLIBC incur a broad attack surface. Attackers can exploit an application by misusing the algorithms and metadata used by the memory allocator itself due to various flaws in the implementation. As a result, there are many exploitation techniques related to the heap. However, these vulnerabilities and exploit techniques are more difficult to understand as they can be dependent on the intricate details of how the allocators are implemented. While stack-based attacks have received significant attention and have various mitigations developed, heap-based attacks remain a persistent threat.

     This paper provides an analysis of the dynamic memory allocation mechanism used in GLIBC, one of the most widely used C library implementations. We describe the key implementation details of the memory allocator, including the use of segregated free lists, in-band metadata within heap chunks and support for multithreading using arenas. We then demonstrate how vulnerabilities can occur in the heap due to incorrect usage of the memory allocation facilities provided, such as use-after-free, invalid free, heap overflow, and others. To illustrate the severity of these vulnerabilities, we provide an overview of two heap exploit techniques: tcache poisoning and fast bin dup. This paper aims to help developers who want to understand how dynamic memory allocation works under the hood and how to avoid common pitfalls that can lead to serious security vulnerabilities.

Exclusion based on stigma is distinguishable from other forms of marginalization because it depends on social consensus about the targets that tends to be shared among a set of people, and is often accompanied by a social justification or supportive ideology for moral segregation. Today more than ever, it is clear through the immense migratory movements, which the provision of a safe and stable place to live cannot be taken for granted. The current world does not offer the conditions of minimum habitability for millions of people. So, what happens when man and habitat do not coincide due to migrating movements? Most of the immigrating parties are uprooted human beings in search of land, looking for a corner in the planet to live, where everyone is entitled to basic rights and freedom. Immigration right is not an issue of ideology, historical debts or revenge, nor donations or contracts; it is a matter of commitment to the Fundamental Rights of Man to ensure a better global future. Considering immigrants world citizens and faced by this type of circumstances we should wonder, what kind of response do these human beings deserve from the self-named Space Designers? What is the true commitment of Urbanists and Architects, if any, within society? Do they have to take positions like that doctor who, forgetting his economic status, turns altruistically to the resolution of others’ pain? Does Culture establish binding commitments to those who are professionally prepared to exercise a job? Should it?

Log files are a great way to find out what's wrong with a system and how secure it is. They can be very large and have a complicated structure, which is why they are so useful. We use Machine Learning (ML) to find network anomalies and build different models that are driven by data to find DDoS attacks. The main goal of this article is to reduce the number of times that DDoS detection is wrongly labeled. In this paper, we describe a method for security analysis that uses Deep Learning techniques like simple LSTM, LSTM with embedding, and Seq-to-Seq LSTM on several systems log files to find and extract data that may be related to distributed denial of service (DDoS) attacks made by malicious users who want to break into a system. Through a process of learning, these data will help to find attacks, predict attacks, or find intrusions. In this study, we looked at how different optimizers, the size of the hidden state, and the number of layers affected the same architecture to find the best way to set it up. When compared to other models, the proposed model was able to correctly identify DoS/DDoS packets that had never been seen before with a 98.95% level of accuracy.

The process of obtaining antimony trioxide from Unified Mining Company S.A. (EMUSA) has two production lines. The refining slag from the second production line was stored since the plant started operations, registering high antimony contents which is the reason for this research project. To recover antimony from the slag, it was necessary to carry out a reducing fusion with slag using pyrometallurgical methods with ternary diagrams; FeO: Na₂O: SiO₂ and FeO: SiO₂: CaO the Sb recovery was done in two parts; the first part consisted of melting in a flame furnace and the second a melting in the IIMETMAT thermobalance. The flow of oxygen necessary for antimony recovery was 0.1 l/min higher flows oxidize antimony and lower recovery. The experiments showed that the reaction that controls the process is PbSb₂ O₆ + 6C= 2Sb + Pb + 6CO. For the melting in the flame furnace, the best slag ratio used was 35:15:50 with the system and with the system, the best ratio was 35:15:50, with Sb recoveries of 98% in both cases.

In recent years, there has been a notable shift from plastic packaging to fibre-based alternatives. Ensuring that fibre-based packaging maintains all functionalities of its plastic counterpart is essential. This research focuses on a specific aspect of this transition: the resistance to water and moisture.

A critical divergence in material properties between LDPE (Low-Density Polyethylene) and fibre-based materials lies in water resistance. The inherent lack of natural water resistance in fibre-based materials underscores the importance of coatings in the success of fibre-based packaging. To address this challenge, two specially designed coatings were developed in collaboration with chosen companies. Following to a promising lab testing phase, a dedicated testbench was constructed for practical real-life evaluations.

Close cooperation with a coating research company played a key role in unveiling the true potential of these coatings. Particularly, a bio-based coating emerged as a viable solution to enhance water resistance in paper packaging.

The demand for lightweight and high-performance materials in product design has increased recently in the automotive, marine, transportation, and aerospace industries (Schweitzer, 2003; Kaufman, 2000). In these kinds of enterprises, losing weight is necessary to increase fuel efficiency, increase payload capacity, and comply with greenhouse gas emission regulations. Using more sophisticated light materials is the most efficient technique to reduce weight without compromising design performance (Mouritz, 2012, Singh et al. 2019a-c). The industry offers a wide range of lightweight technical materials, such as alloys made of titanium, magnesium, and aluminium. Aluminium alloys are widely utilised in the aerospace, transportation, shipbuilding, and other industries due to their high strength to weight ratio and resistance to corrosive agents.

When considering the technical and systemic concerns of the sustainability of science centres as agents for science awareness, communication, engagement and education that are at the forefront of Fourth Industrial Revolution (4IR), the impact of science centres on the National System of Innovation (NSI) interventions should certainly be measured empirically, through monitoring, evaluation, and review mechanisms. This paper argues that science centres have a key role to play in Science, Technology and Innovative (STI) imperatives as well the Fourth Industrial Revolution (4IR). To this end, the South African Framework for the Promotion of Excellence in a National Network of Science Centres (2005) is evaluated. Moreover, the positioning and role of science centres in this landscape is examined, in terms of science awareness, communication, engagement and education. The case study of the Sci-Bono Discovery Centre - the largest science centre in the Southern Hemisphere - will be utilised to further understand the role of science centres in the NSI, STI and the 4IR.

In recent years, under the background of the raging of COVID-19, intensified regional conflicts and rising trade protectionism, global economic development has been seriously challenged. Many small countries with a single economic structure have been hit even more severely. Many of them are on the verge of economic collapse as domestic economic and social contradictions have intensified. This paper will analyze the reasons for Sri Lanka's national bankruptcy from three perspectives. It is hoped that more countries in a similar state can be warned and that international economic organizations can identify other countries that may be at risk of collapse more quickly and accurately and provide timely support to reduce economic losses and maintain national security. The paper will use methods such as literature analysis, data analysis and case analysis to try to explain the reasons for Sri Lanka's national bankruptcy. In the end, the article categorizes the reasons for Sri Lanka’s bankruptcy into three points: a) unresolved domestic economic problems for many years, b) three policies implemented under the misjudgment of the new government, and c) the fuse of COVID-19 and the Russian-Ukrainian war.

Platelet-rich plasma (PRP) is autologous blood product, that contains platelets concentration two to three times above normal blood level. As such, PRP is a rich source of different bioactive molecules including grow factors, enzymes, cytokines, and chemokines. Beside its regenerative properties, a limited number of studies has proven that PRP can induce antimicrobial effect against single growing pathogens and biofilms. Aim of this study was to analyze PRP antimicrobial effect against three most common biofilm forming bacteria, including S. aureus, E. coli and P. aeruginosa. The antimicrobial property of PRP was evaluated after 24 h of incubation with selected bacteria in Brain heart infusion (BHI) media using spectrophotometer with a light source of 600 nm. To check whether PRP can inhibit bacterial biofilm formation, after 24h incubation, tube screening test (TM) was applied. Bacteria treated with PRP and platelet poor plasma (PPP) were compared with untreated control, composed of bacteria growing spontaneusly in BHI media. PRP produced strong growth inhibiton in all tested bacteria when compared to bacteria treated with PPP and control group. Based on the obtained results it can be concluded that PRP can induce antimicrobial effect on S. aureus, P. aeruginosa and E. coli. PRP also reduced biofilm formation for P. aeruginosa and E. coli. However, there was no effect on S. aureus biofilm formation.

The environmental and socioeconomic effects of mining and human security challenges are a source of worry to most governments all over the world. It is a known fact that the extractive industry - mainly gold, diamond, manganese and crude petroleum contributes significantly to the national economy of most countries in Africa inclusive of Ghana. However, in spite of its importance to the national economy, its effects especially on the environment, the health of the people, food security, fundamental human rights of people in communities where illegal mining occurs affects the human security of the citizenry. Uncontrolled illegal mining is prevalent in Ghana even though there is a legal regime to check and control artisanal and small-scale mining. In view of its destructive consequences, a securitisation approach is usually used to justify the deployment of “security forces” to deal with the menace in view of the multiple dimensions of insecurities that is associated with illegal mining. The adoption and use of human security paradigm allows for the taking of a more integrative and holistic approach in dealing with the problem in the country. Studies on illegal mining in Ghana confirm that, poverty accounts for the main reason why people risk their lives to engage in the practice. This paper provides a review of the effects of illegal mining on human security in Ghana. It aims to reveal the multiple insecurities surrounding illegal gold mining in Ghana from a human security perspective. Further, the paper make recommendations for governance and policy reform in finding solution to the insecurities associated with the practice.

The goal of this paper is to research if there are any relationships between intellectual capital and “neuromarketing”. The first appears implicitly (because it results from skills to design technologies), while the second appears explicitly (in technologies such as “eye tracking”, GSR, FEA, fEMG, …). The literature on “neuromarketing” has focused on the consumption and promotion of products and/or services. Its practices, for research purposes, have faced obstacles on the part of companies, which make their evolution difficult. On the other hand, credibility is attributed to “neuromarketing” results if they coincide with what is expected. If they are not, nothing can be said, and only further research will be able to provide answers. In this case, paradoxically, it makes “neuromarketing” progress, once the obstacles associated with available information are removed. Finally, it is worth highlighting the fact that “neuromarketing” technologies reveal “ironic behaviors” in consumers (ironic revelation): what consumers reveal they prefer is opposite to what the application of technologies such as those mentioned above reveal.

Thus, the pillar of intellectual capital will be the source of the development of “neuromarketing” and vice-versa. This research makes it possible to highlight this contribution and the implications for better understanding the preferences revealed by consumers. However, there is still a long way to go to understand the origins of these changes.

The application of the recently suggested probabilistic design for reliability (PDfR) concept [1-5], an important extension of the design-for-reliability (DfR) effort (see, e.g., [6]), enables improving the state-of-the-art in electronics and photonics reliability engineering by establishing and assuring the adequate reliability level in many critical reliability tasks in these areas engineering. This is particularly important in various human-in-the-loop (HITL) [7-9] situations, when the reliability of the equipment/instrumentation, both its hard- and software, and human(s) performance contribute jointly to the outcome of a critical mission or an extraordinary situation. The PDfR concept provides a way to predict the, in effect, never-zero probability of the field failure of the product of importance by putting the reliability predictions and assurances on a well substantiated quantified "reliable" basis. The concept does that mostly on the basis of the highly focused and highly cost effective failure-oriented-accelerated-testing (FOAT) [10-14] conducted on the design stage of a new technology, new design, or a new application of the existing technology or design, when the highly popular today highly-accelerated-life-testing (HALT) [15] does not yet exist for this product and technology, and suitable best practices have not been developed. Note that there are also two other FOAT types: those that are almost always conducted at the post-manufacturing stage and known as burn-in tests (BITs) [16-18] and those that are quite often conducted on the product development stage, such as, e.g., shear-off and temperature cycling tests.

A series of welding process tests were carried out for the pressure resistance spot welding (RSW) of the hexagonal tube and the grid frame component of MOX fuel assembly in CEFR. With the help of visual inspection, metallographic inspection and tensile test at room temperature, analyzing the influence trend of single welding parameter on the nugget diameter and mechanical properties. A set of optimal welding parameters is obtained by considering the influence of welding current, welding time and electrode pressure on the quality of welding joints. The results show that when the welding current is 3kA, the welding time is 8cyc (1cyc=1/50Hz), and electrode pressure is 350N, the diameter of the soldering core and the tensile force of the welding joints are relatively stable.

In the last decade, research on gamification increased in various fields such as mobile apps, e-health, human resource management, business development, and e-learning. However, research on gamified mobile applications is still fragmented, and a systematic overview of gamification in education engineering is missing. Thus, we conducted a systematic literature review of 43 empirical studies to explore state of the art in integrating gamification approaches into mo- bile apps. The literature review covers gamification design elements, psychological outcomes, behavioral outcomes, research areas, and the effect of gamification. The results show that rewards are the most commonly used design element of gamification in mobile apps. Gamification has a potential impact on psychology and behavior and provides positive benefits. The review's findings extend the knowledge base by providing insight for further studies and the design of gamified education engineering systems.

A population of 430 million people and above, or over a population of 5% of the world's population, needs therapy to treat their "disabled" hearing and speaking condition. These people have the option to learn sign language to communicate with others. Hence, our project mainly targets the deaf and mute community. Around 5000 images of hand gestures have been used and divided into 10 categories for live detection. The categories are mainly American Sign Language (ASL) and are consisted of the first 10 numbers. Our model can detect these ten hand motions and categorize them correctly. We used the You Only Look Once Version 5 algorithm. The algorithm consists of a backbone namely CSPDarknet53, in which an SPP block is accustomed to accelerating the speed of the receptive field responsible to set apart prime traits and confirming that network operation speed is inclining in speed. The neck of the algorithm, PAN, is added to aggregate the parameters from different backbone levels. This model is very easy to use and understand and gives an accuracy above 98%. That is why we chose YoloV5 as our model for object detection due to its simplicity in usage. Therefore, an artificial sign language detection system has been suggested in this study which incorporates deep learning and image processing method. This study also gives a comparison between the two models to give a better understating of why we marked YoloV5 as a better algorithm even though both models gave an accuracy of above 98%. We believe that making a hand gesture detection system will encourage individuals to communicate with people who cannot hear or speak. That being the case, we aim to make the lives of the disabled better.

In South Africa, adopting a paradigm of “Futuristic Science Engagement" is particularly important. It is about finding that intricate balance between hindsight, insight and foresight. In other words, such a paradigm can be synthesised through the combination of learnings from the past, accurate analysis of the present, and a holistic vision for the future. Indeed, the world is changing rapidly, evolving in real-time, partly due to the ingenuity and innovations of science practitioners. However, within the broader context of Science, Technology and Innovation (STI), there are many actors and agents, experts and laypeople alike, who feed into the country’s National System of Innovation (NSI). Inputs into the NSI to cultivate and generate synergistic outputs include the political, economic, and social, over and above the STI aspects. This paper proposes a holistic barometer for measuring the impact of STI interventions. It argues that a synthesis of futuristic science, if defined as a convergence of hindsight, insight and foresight, requires an integrated approach that includes policy imperatives, socio-economic imperatives, epistemological imperatives, and ethical imperatives. To this end, the historical journey of South Africa’s NSI, its policy frameworks, and its continental commitments based on African Union policies are traced as the hindsight component; the socio-economic status as well as South Africa’s current standing in the 2023 Global Innovation Index (GII), are engaged to draw out relevant insights. Discourse on knowledge production that has contextual integrity, which speaks to the epistemological foundations of the system, as well as the role of the ethical in the era of a Fourth Industrial Revolution (4IR), are the foresight components to be considered.

Although I’ve been studying and applying the Guide to Project Management Body of Knowledge (PMBoK) of the Project Management Institute (PMI) since its first edition in 1996, and although for various reasons I attended twice the 35 hours’ related preparation course for the Project Management Professional (PMP) certification exam, I never applied for such certification. Nevertheless, three years ago, at the age of 64, almost at the end of my forty years, very rewarding career, I submitted my qualifications and the required report on one of my last projects, sustained a long and tough interview, and finally got the Project Manager Certification according to ISO 21500 - and to the related Italian UNI 21500 and UNI 11648 - which reflects faithfully the PMBoK: as a matter of fact, representatives of both the PMI and the International Project Management Association (IPMA) were on the board who wrote the international regulation, together with the representatives of the 25 national standard unification agencies that promoted the ISO 21500.

Nowadays, several video movement classification methodologies are based on reading and processing each frame using image classification algorithms. However, it is rare to find approaches using angle distribution over time. This paper proposes video movement classification based on the exercise states calculated from each frame’s angles. Different video classification approaches and their respective variables and models were analyzed to achieve this, using unstructured data: images. Besides, structure data as angles from critical joints Armpits, legs, elbows, hips, and torso inclination were calculated directly from workout videos, allowing the implementation of classification models such as the KNN and Decision Trees. The result shows these techniques can achieve similar accuracy, close to 95%, concerning Neural Networks algorithms, the primary model used in the previously mentioned approaches. Finally, it was possible to conclude that using structured data for movement classification models allows for lower performance costs and computing resources than using unstructured data without compromising the quality of the model.

The powerful narrow beam of single wavelength light that laser produces was the first “solution looking for the problem in 1960”. Theodore Maiman created it 1960 by illuminating a high-power flash light on a ruby rod on a silver coated surface at California’s Hughes Research Laboratory. From the most cutting-edge quantum physics labs to hospital. Laser is now ubiquitous in modern science and technology. When a laser heats up its target, a phenomenon known as photothermal interaction occurs. Proteins are denaturized, mitochondrial membrane permeability is enhanced and the mitochondria eventually evaporate. In this paper Monte-Carlo simulation method is used for the Laser tissue interaction.

The Federal Reserve has raised interest rates four times in a row, twice by 75 basis points from June to July, totaling 150 basis points, since 2022 in an effort to reduce the rising inflation in the United States. This is the most important development since 1980. After the rate hike in July, the policy rates of the United States have reached a range from 2.25% to 2.50%, which is widely considered by dozens of people as a "neutral rate" level. Since the U.S. dollar is the dominant international currency and controls the world's financial, monetary, and trade settlement systems, the Fed's interest rate hike has an impact on the world financial market. Bitcoin has become a financial asset traded on a global scale and has gradually become popular in financial market transactions. With the Fed's rate hike, a considerable number of investors in the cryptocurrency market are very concerned about the impact of the Fed rate hike on Bitcoin, and then reassess the risks to ensure their own interests. This paper searches and obtains data on the Bitcoin price and USD/CNY exchange rate from June 1, 2021 to August 15 2022. This paper uses VAR and ARMA-GARCH models to study the impact of the USD-CNY exchange rate changes on the rate of return and volatility of Bitcoin.

In a Real Time System, when a high priority task is scheduled, it preempts ongoing lower priority tasks and sometimes it preempts even the kernel too. In normal cases, the time needed for the preemption is too small and hence is not considered in task scheduling. But, in some mission critical hard real time systems, even a small fraction of a second should be taken into account as it could affect the deadline. This research work proposes two models - embedded model and software model, among which the latter has been used for the experiment that calculates the kernel preemption time. The hardware model consists of a triangular wave generator called TRIANG that takes timer values from real time tasks and sends outputs to a comparator module. Finally, the comparator compares the time differences, and hence, calculates the kernel preemption time. Whereas the software model uses the RT-Linux architecture in which device drivers are used instead of hardware components. A high precision timer clock is also used to measure the task release times.

The results from the experiments show that the release time jitter due to the kernel preemption is found to be fluctuating in the range of -94 and +93 microseconds in 3% of the cases. So, the kernel preemption time for the hard and mission critical real time systems is taken to be less than 99 microseconds. Whereas 85% of the cases have release time jitters of single digit only. So, the kernel preemption time in average case is considered to be less than 9 microseconds.

     In the realm of cutting-edge technologies, quantum computing stands as one of the most revolutionary and promising fields. While classical computers have served us well for decades, they are reaching their limitations when faced with complex problems like optimization, cryptography, and simulating quantum systems. Quantum computing harnesses the principles of quantum mechanics to process information in ways that classical computers cannot, opening the door to new possibilities in various domains. Quantum computers can solve problems that are impossible or would take a traditional computer an impractical amount of time - a billion years to solve.

     Since the early 20th century, when the atom was first investigated, quantum physics has defied logic. It turns out that atoms do not apply the standard principles of physics. Quantum particles have the capacity to "teleport," move through time, and exist in two places at once. The goal of quantum computers is to exploit these unusual behaviors. At the heart of quantum computing lies the concept of qubits, which are the quantum counterpart of classical bits. While conventional bits can only represent a 0 or a 1, qubits can simultaneously exist in both states. This unique property allows quantum computers to perform multiple calculations at once, offering a potential for exponential speedup in specific tasks.

Sustainability plays a crucial role in engineering across various disciplines and industries. It involves designing and implementing solutions that meet the needs of the present without compromising the ability of future generations to meet their own needs. In the context of engineering, sustainability encompasses environmental, social, and economic considerations. Here's how sustainability influences engineering:

Environmental Impact Reduction: Engineers have a significant impact on the environment through the products and systems they design. Sustainability in engineering involves minimizing resource consumption, reducing pollution, and minimizing the release of harmful emissions and waste. This can be achieved through efficient design, materials selection, energy-efficient technologies, and waste reduction strategies.

The growth of the car industry is now closely linked to the rise of the number of car accidents. As a result, insurance companies must deal with several claims at the same time while also addressing claims leakage. To resolve these issues, we propose a car damage detection system based on Mask Scoring RCNN. The experiment first makes a dataset by collecting car damage pictures of different types and on different angels for pre-processing then use Mask scoring RCNN for training. It is envisaged that this method would assist insurance in correctly classifying the damage and reducing the time spent on damage detection. The test results demonstrate that the proposed system has better masking accuracy in the case of complex images, allowing the car damage detection duty to be completed swiftly and easily.

The process of sorting onions systematically is called onion sorting. Manual onion sorting is preferred at the wholesale market and in the farming, sector based on different parameters such as size, shape, quality, etc. It is not however a more efficient, consistent, and time-consuming method. In the market, there are systems that can sort single onions based on a single set of parameters. To replace this traditional way of sorting onions, In this paper we are introducing “Automatic Quality Based Onion Sorting Mechanism Using Raspberry pi”. The proposed system combines an automatic onion sorting mechanism with an image processing technique and classification algorithm. E.g., quality-based analysis. This machine can be used for agricultural purposes, and it can also be employed in the food industry.

In the 21st century, one technological marvel stands out among the rest, promising to revolutionize industries, reshape economies, and redefine the very nature of human interaction with machines. Artificial Intelligence (AI), once confined to the realm of science fiction, has firmly established itself as a driving force in today's world. The transformative potential of AI is undeniable, but with great power comes great responsibility.

     Hydrogen production around the world continues to grow rapidly.

     Analyzing some hundred projects already active or under construction across the planet, in the United States, Europe and China, even though in very distinct ways and with different targets, we are searching all the reasons, numbers and goals in details, to understand how our world could benefit from it, in the field of e-mobility, but also of heating and industrial applications.

     To fully understand where the energy sector is heading with this new “water-based fuel”, or even “valuable alternative to natural gas”, it is important to place it briefly within the world economy.

     Imagine a substance largely present in the universe, with good energy efficiency which, if produced correctly, can be 100% sustainable and useful for powering all those machineries and systems that cannot be equipped with a battery pack or with a traditional engine, and therefore do not depend exclusively on electricity from the public grid or renewable, or even from fossile.

Construction in Cape Coast Metropolis has been impacted by the cost increase of public building construction projects in Ghana. The goal of this study was to evaluate how well Cape Coast Metropolitan Assembly (C.C.M.A.) construction projects performed in terms of cost. The study used a qualitative approach to gather its data. During the fieldwork period, forty (40) structured questionnaires were given to contractors working on C.C.M.A. projects. The data analysis was done using the Statistics Package for Social Sciences (SPSS), and the results were displayed using relative index ranking and descriptive statistics. The survey results show that the main causes of cost overruns in projects within the C.C.M.A. were variations in material prices, differences in currency exchange rates, high machinery costs, inaccurate or inadequate estimates of the original cost, and frequent variations or change orders. The study makes the following recommendations: projects should have an adequate scope, effective project costing and finance, and qualified staff should be used in the administration of the projects.

India, a diverse nation, stands to be a unique democracy today because of the forces that shaped its policies and structure. The oppression of the colonial rule inspired independence, sovereignty, and other core values of the current government. A diverse and pluralistic society was accommodated through a representative government that committed itself to democracy. Its legacy as a colonized state made the agenda clear: to avoid a concentration of power and to give the people a voice. This was exercised through political processes like elections. Eventually, the structure and the very functioning of the state were formed through the influence of these factors. This paper will elaborate on the current political structures in India and the role of the agents.

     Automation is neither a purely positive force nor an entirely negative one. It's more like a process, and its impact depends on your perspective. In simple terms, automation involves using technology to handle tasks or create products. Keep in mind that humans create technology; technology doesn't create humans. Let's break this down further.

      For some people, like those with disabilities, automation is a boon. It allows them to lead happier lives by using technology. In today's society, where differently-abled individuals might face challenges and lack motivation due to societal attitudes, automation becomes a crucial tool. It enables them to experience the world on their terms. Even if they have physical limitations, they can still excel and make a positive impact thanks to automation.

The COVID-19 pandemic has had a significant impact on the manufacturing sector including Malaysia, causing supply chain disruptions, decreased demand, and production shutdowns. This has resulted in a decrease in output and disruptions to global trade, with some sectors rebounding while others continue to struggle. Industry 4.0 technologies, such as the Internet of Things (IoT), artificial intelligence (AI), big data analytics, cloud computing, and real-time data visualization dashboard can assist manufacturers in overcoming these challenges by increasing flexibility, efficiency, and resilience in their operations. Real-time data visualization dashboard tools, a technology from Industry 4.0, can provide operational insights into manufacturing processes, and help identify areas for improvement. These platform can also assist in remote monitoring, management, and predictive analysis, which can help manufacturers mitigate the effects of the pandemic and become more resilient in the face of future disruptions. This research studies among Malaysia's manufacturers have found that the majority agree that Industry 4.0 is more valuable during and at post-pandemic, with real-time data visualization tools being the most important elements for tackling the top issues such as inventory management and process yield improvement. However, many manufacturers are still in the pilot run, and there are challenges to be faced in the post-COVID-19 recovery phase, including managing organizational mindset, culture, and customer needs.

Intrusion Detection System is software or hardware that checks a network for malicious activities. Each illegal activity is often recorded either centrally using a Security information and event management (SIEM) system or notified to an administration. This paper proposes an intrusion detection system using machine learning algorithms such as decision trees, random forests and explainable AI (XAI) using a real-world Software-Defined Networking (SDN) dataset. The evaluation includes various intrusion scenarios like network scanning, denial of service (DoS) attacks, and unauthorized access attempts. Random Forest exhibits the best performance, achieving an average training accuracy of 99.23%, while the decision tree achieves 98.78% accuracy. The result of this study contributes to the advancement of intrusion detection systems and fosters the development of resilient security solutions in the realm of SDN. The research highlights the importance of leveraging ML algorithms in effectively identifying and mitigating network intrusions, ultimately enhancing the security of SDN environments.

Neural network models have been exploited since the late ‘80s and ‘90s to solve real-world problems, based on the then contemporary developments such as the back propagation learning algorithm. Over the last decade, the availability of massive data sets, enhanced computational resources, and further developments in algorithms have led to an explosive growth in the use of neural networks in machine learning and artificial intelligence. They showcase the state-of-the-art performance in artificial intelligence applications, all the way from speech comprehension and image recognition to cross-modality translation. In parallel, however, an analogously related perspective, elegantly relating the spheres of cognitive neurobiology and machine learning, has spurred interest. All the more, both sides of this stance seem to entail far-reaching implications.

This research focuses on the industrial development of Istanbul and the planning of housing and industrial areas. It examines the city's urban agenda, which is dominated by internal and transnational migrations, population growth, housing problems, and the process of opening new housing areas over many years. Another significant issue is the planning of industrial areas and their impact on the city. Climate-related issues and agreements like the Paris Agreement in 2015 emphasized the detrimental effects of industrialization, uncontrolled urban sprawl, decreasing green areas, industrial pollution, and high carbon emissions in cities, making them more problematic. The problem of uncontrolled development of residential and industrial areas has persisted for many years. The idea of permanently moving industrial areas outside the city, to nearby towns, has been long known idea proposed at the beginning of the 20th century. However, various political challenges and other factors have hindered the effective implementation of this approach. The main concern is that this problem poses a potential threat to the future sustainability of the city. The research examines the reflection of industrialization and urban planning over nearly a century, up to the present day, by analyzing the planning reports of the Istanbul municipality and government policies on the subject. The findings indicate the importance of zoning applications in the planning of industrial and residential areas, as applied in world cities like London and Paris. However, the idea of decentralizing industrial areas in the city, though theoretically supported in development plans and reports, faces challenges in practice, affecting the city's future sustainability. The research highlights the complexities involved in addressing industrialization and planning issues in Istanbul, emphasizing the need for effective policies and strategies aligned with sustainability principles and long-term urban development.

Indicators of the quality of functioning of the rail crew with given mass and, as m_i well as geometric characteristics, are completely determined by the parameters of its spring suspension − spring stiffness J_i and attenuation coefficients ofvibration dampers. When choosing these parameters, it should be borne in mind that they have an ambiguous effect on the dynamic properties of the crews and, consequently, on their quality indicators. On the one hand, an increase in the coefficient attenuation reduces the amplitudes of the coordinate and improves the safety factor of the structural deflection of the springs. On the other hand, such a decrease leads to an increase in active forces in spring suspension and, especially, accelerations in the resonant region, which worsens such quality indicators u_i (where i = 1, 2, …, n) as maximum body accelerations and dynamic overload coefficients.

Brain computer interfaces (BCIs) are the technologies that transforms commands for operating devices from electrical activity in the brain. Most BCI systems consist mostly of hardware and software. Hardware is gathering the data while software interprets the brain's input and feeds it back to the hardware. In this article, we give a summary of the publicly accessible software platforms for brain-computer interfaces. Five significant BCI platforms have been determined by us. We outline the intended target user group (which consists of academics, programmers, and end users), as well as the key characteristics of each platform, including their compatibility with various operating systems, licensing, supported devices, and programming languages. BCI2000, OpenViBE, TOBI Common Implementation Platform (CIP), BCILAB, and BCI++ are the five platforms under question. In our conclusion, we address potential synergies and potential future advances, such as merging diverse platform components. With this analysis, we intend to highlight the benefits and drawbacks of each platform that is currently accessible, which should aid anyone working in the field of BCI research in choosing the best platform for their individual needs.

We have experienced reduced radioactivity in contaminated soils in Fukushima since 2011 using specially processed water. The results indicated a drastic decrease in radioactivity by changing the radioactive cesium to stable barium without applying substantial energy. We repeated our experiments using water decontamination on Fukushima farms. On the base decontamination evidences, our research presents new insights into applying high pressure (> 100 MPa) to seawater at various locations in the Pacific Ocean. We found element changes by chemical analyses of elements in the seawater to compare them before and after the high-pressure process. Water may form a presumed particle after the dissociation of hydrogen bonds by 147 MPa. Then, we discuss the theoretical viewpoints that element changes occur with the weak energy due to pair of electron and proton in hydrogen atom of water. This work involves the behavior of a proton and an electron pair, and we focus on their nuclear spins. We develop the conversion of sodium to magnesium, cesium, and barium with the presumed particles.

This paper seeks to do a brief literature review about what is most recent in the topics of intellectual capital and accountancy, their relationships and their usefulness for scientific knowledge. Research question: what do the papers that consider, alone or together with others, these 2 topics reveal? Do they present something new, not expected at first? Are they useful for scientific knowledge? It was found that the research confined to these 2 is very meager, falling short of what would be expected in terms of usefulness for scientific knowledge, and could be broader if it included other topics (technology, performance, environmental management, …). The methods used were questionnaires, Likert scale, econometrics and financial statements of firms. As main results and conclusions, we can mention that the dimension of intellectual capital has positive effects on firms´ performance, and variables able of improving it were identified. Environmental management accounting has a positive effect on business decisions and information systems accounting also has positive effects on the efficiency of workers. The geographic areas that served as context were Italy, Indonesia and Jordan. The temporal context in which the research was carried out in 3 papers was omitted, deliberately or not, which reveals a lack of detail.

     I regard a cooking in our everyday constituents engineering when we look at our work in cooking room; See if the meat is cooking at the right heat. Heat relates really physics. Calorific value of “right heat” is thermodynamics, and taste control is supposed to be a chemistry besides human tasting which is difficult to define. Seasoning is to form a compound with the materials by reaction with it.

Though Storage-as-a-Service, provided by cloud service providers (CSPs), is a paid program that allows enterprises to subcontract important documents to be kept on faraway systems, information security is one of the most significant issues when embracing Cloud services. Users may save their devices electronically and avoid the hassles of storage device and upkeep in a Virtual environment. They do, however, lose ownership of their knowledge throughout this procedure. Current solutions do not address all aspects, such as the cloud's complex nature, compute and network latency, and so on. A Data Storage Security Mechanism is proposed for achieving storage consistency while preserving minimal compute and analysis based in the Internet. Furthermore, using buzhash, a B-tree is generated for saving the hash value of the information in its branches as well as file systems. As a result, the space overhead of secure file computing and storage is reduced. Then there's Promotes Self Cybersecurity, which is aimed to increase interaction data in cloud mobile internet providing in a short amount of time. For each session, it generates self-updating randomized key pairs. The experiments show improvement in terms of improving cloud security and privacy while lowering network latency.

In this paper we are trying to proposed a model of smart-parking for smart-city. Parking in a city is one of the biggest problems. Many times, it was observed that Instead of finding a parking zone or parking space nearby people park their vehicles on road which in traffic and because of this ambulance stuck in traffic jam which results in death of many patients because they are unable to get medical facilities on time. The objective of this paper is to propose a relevant system that will provide a more accurate location system thus helping in deciding the positioning of the parking system by detecting the free spaces in a parking lot and letting the driver know about the location that can be allocated to him. The system also deals with proving the accuracy that cannot be achieved by global positioning system as this system works on the neural network algorithms that break the information down to a matrix and analyze the data to deduce conclusions that would help find an appropriate parking space for the person on the real time basis. The objective of this paper is to reverse the adverse effect of the wrongly parked vehicles.

In this paper, we delve into the realm of cloud computing, which has experienced exponential growth due to its ability to rapidly deliver IT services at a minimal cost. Virtualization has played a crucial role in enabling the cloud model, but it is worth noting that virtual machines tend to be slightly heavier compared to containers. This is primarily due to the use of a hypervisor on the underlying operating system, while containers utilize a lightweight container manager. With the abundance of alternatives available for Docker containers today, our objective is to elucidate the concept of Docker containers and conduct a comprehensive performance comparison with its alternatives. Our aim is to provide individuals and organizations with valuable insights, enabling them to select the optimal virtualization platform that aligns with their specific requirements.

We focus on essential part of water, which is the basic substance on the earth. Nobody looks at a single water molecule; and an established theory has not been how many molecules of H₂O combine to form a cluster. Most research on water starts from H₂O unexpectedly. Our essential research of water is the dissociated water of the hydrogen bonds although the hydrogen bond itself seems to be established in water. But our researh is about the presumed particle of H⁺ and e^- in a hydrogen atom. It is not the atom, neither the H₂ molecule or the OH ion. The present study’s central theme is to clarify the collaborating function of spin and charge, We propose the particle equation instead of wave function. Furthermore, we approach information-transfer by way of collaboration of proton and electron in the atom to form a field in any substance, even in space. In the future we will make clear the potential of the infoton which is difficult to define because it is a space function, and spins, charges, and momentum may entangle associating with information-transfer as well.

Scientific evaluation of driving behavior can provide feasible suggestions for improving driver operating habits, improving driving safety, and reducing energy consumption. It is also of great significance for the development of autonomous driving functions. The existing evaluation methods for driving behavior have shortcomings such as subjectivity and randomness, and neglect the ambiguity of human judgment. This article proposes an overall evaluation system based on the extension analytic hierarchy process based on real driving data collected from real vehicles. Grey clustering and fuzzy comprehensive evaluation are introduced to evaluate the driving behavior of drivers from four key indicator dimensions, effectively improving the accuracy and scientificity of driving behavior evaluation.

     The problem of determining the source has been analyzed during the last years in different areas of ap- plied mathematics and has received considerable attention in many current research, as it has applications in fields such as driving of heat, crack identification, electromagnetic theory, geophysical prospecting, the detection of contaminants and detection of tumor cells, among others.

     Source identification from noisy measurements is often a problem ill-posed in the sense of Hadamard since the solution does not depend continuously of the data. Among the most important tools used in the literature to determine a source can be found: the potential logarithmic method [11], the projective method [10], Green’s functions [2], dual reciprocity boundary element methods [1], the dual reciprocity method [14], the fundamental solution method [3].

The globalization of the economy, the major disruptions due to the COVID-19 crisis, customer requirements as well as the current context of war, are straining global supply chains, which must demonstrate resilience and constantly seek to improve their performance. performance. Among the essential approaches to achieve these objectives, collaboration between logistics partners through methods and tools that have proven themselves but also have shown limits, particularly in terms of trust. Blockchain technology, which appeared in 2008, now offers an opportunity to improve collaboration by providing answers to concerns about trust. However, its application is not generalized, indeed a large part of the companies do not apply the technology because of its shared database character because the companies have sensitive and confidential data. After an analysis of the literature to highlight the obstacles to the generalization of the use of the blockchain in the supply chain, a methodology of adoption and application of the Blockchain following eight steps is proposed with an emphasis on the smart contract.

Kidney disease is a significant health concern that is currently affecting individuals of all age groups. To predict the occurrence of chronic renal disease, a large number of scholars have employed machine learning and deep learning techniques. However, the efficacy of these methods is often hampered by a lack of transparency, which is a major issue in the application of artificial intelligence in healthcare and medical analysis. As such, the lack of clarity has prompted concern. To interpret the results of predictive models, the present study proposes the deployment of four machine learning algorithms, including Decision Tree, Logistic Regression, Multi-layer Perceptron Classifier, and Support Vector Machine, in combination with explainable AI (XAI) interface, leveraging the local interpretable model-agnostic explanation (LIME) and shapely additive explanation shapely additive values (SHAP). The proposed models are intended to facilitate effective decision-making in clinical research and therapeutic practices.

Nowadays scientists pay special attention to the fact that all engineering tasks should be set and solved from the standpoint of combating climate change by reducing greenhouse gas emissions. The proposed and used materials and technologies should have a low carbon footprint and comply with the principles of developing a green economy.

     All buildings, in all climatic regions, emit CO₂. This is because buildings use energy for lighting, water supply, heating, cooling, ventilation, appliances, and technological processes. For these purposes, it is advantageous to use clean renewable energy. The building is always in interaction with renewable energy, including incoming solar radiation and the environment surrounding the building [1]. Thus, the environment has the thermal potential of the outdoor air, soil, wind, sky, and surfaces facing the building [1, 2]. By ensuring the expedient daily and seasonal interaction of these energies with the building, it is possible to create a comfortable, stable, and economical internal microclimate. For example, energy consumption for heating, cooling, and ventilation can be reduced.

     Structural sandwich panels with core of Advanced Composites Laminates Honeycombs/PU-foams are extensively used in aero- space applications and these are also fabricated for use now in some civil engineering applications. An all Advanced Composites Foot Over Bridge (FOB) system, designed and developed earlier for pedestrian traffic is one such application [1] that may be cited here as an example. During development stage of this FoB, the profile of its decks then spurred out was a single corrugate sheet core sandwiched between two Glass Fibre Reinforced Plastics (GFRP) flat laminates. Once fabricated and successfully used, these decks did prove suitable on their assembly, to form other structues such as erecting temporary shelters. Corrugate sheet core profile sandwiched panels have also been tried using the construction materials but in any conventional method of construction as existed, posed certain difficulties in achieving the required core profile without any bonding within the sandwiched slabs and hence its use remained only abandoned. The required monolithic construction becomes now as eased out with demonstration on dispensing of suitable materials through 3D Printers. An study was conducted which included first, the fabrication of a 3D printer in-house (already patented [2]) and then make use of them as well. On functional operation, more complex sandwich core profiles have then been 3D-printed out and thus produced the number of panels hard-ware. Initially, number of these sandwich panels in single corrugated sheet core monolithically were printed out, which were subjected to load test in an experimental set up [3] and their structural behavior studied analytically, correlated and were also reported earlier by the Author as in the literature [4]. It was observed from the 3D printed hardware that the presence of any corrugate core in any sandwich core profile although provides continuous support to the loaded face sheets of the sandwich panels in their longitudinal direction, in their transversal direction however, this corrugate core still remains supporting the face sheets at periodic intervals only. Therefore it is felt that adoption of such core profile creates a vast difference in the available shear resistance between the longitudinal and transverse directions on flexural bending of any of such sandwich panel under application of, for example, uniformly distributed load. To over come this and also attempting to achive the required more depths further so as to exhibit the stronger sandwiched decks with better structural and mechanical behavior, more complex core configuration such as that of dual corrugate sheets core with a flat mid plane was felt to be a better sandwich core profile and therefore panels of different geometries were created in a good numbers, as shown in figures 1, a few of those circular and figure 2(a&b) shows a few of rectangular/square panels. Such an exclusive profile has been an outcome that turned out merely on stacking of two separately 3D printed units of single monolithic corrugated sheet core so developed earlier as briefed above and on initially bonded them together but maintaining here, a certain different orientation in the two corrugate layers. For any required sequential understanding of the structural behavior of any such complex core profile sandwich decks with special emphasis to study analytically, the effect in variation of such corrugation orientations in each distinct tire of the core, some fruitful findings obtained and those were reported elsewhere. It has been observed here that a flat layer which eventually get created monolithically in the middle, in addition to eliminating any bonding process in these sandwich panels development, it has been found also to offer, much more effective bending resistance by these sandwich panels when subjected to any loads over them.

     Home health care management is a viable aid to public health care for the Caribbean especially in the midst of high health cost and dwindling resources in these economies. Managing personal health vitals data from the comfort of the home using technology is a growing approach worldwide and suitable for those who are convalescing, recovering from stroke, surgery, general ailments and for persons just wishing to monitor their health vitals. Sensitization of the public to the advantages of a Telehealth Home Health Care System in realizing hospital avoidance for some illnesses may promote the desire for it. (Ledwin KM, Lorenz R, 2021). This in no way however removes the need for input from the nurse or clinician delivery since the lack of this may increase patient anxiety and satisfaction with the system. (Jolly K, 2018).

We report the hydrogen-based nuclear magnetic resonance (H-NMR), super quantum interference device (SUQUID) and electromagnetic field associating with spin which is a tiny device. Although spin has described in an angular momentum in quantum physics, the methods have not been established to detect a spin directly. So, we employ the HNMR and SUQUID in order to identify magnetization of the material. As one of examples of water, we introduce the difference of water every location. Furthermore, we explain nuclear transformation of radioactive cesium with spin. On the other hand, we discuss the interesting device of an electromagnetic field to engage placer gold and paramagnetic aluminum (insulator) in the resin as one of the medical treatments in the future. We estimate the system to discuss with spin.

The Internet of Things impacted the Indian industry in a more thrilling way than expected. India realised the actual uses of this technology in the year 2020, and we all knew what happened during that year, "The Covid Pandemic". The IoT-based system has been in the market, most probably since 2009. 11 years is a long period to make a difference. However, we realised the true potential of a lot when we had limited resources and a limited workforce. So we needed more automation & quick Production of essentials. See everyone says that the pandemic has been a curse to all of us, but in my opinion, no it has not been one. Our industries optimised productivity, adopted precautionary measures for safety during this period, and built an overall safer environment for enterprise operations. This has enabled enterprises to take on loT-enabled management systems in 2022 Before the pandemic, only a few Jarge entrepreneurs knew about the lot-based management system which is quite easier than the old process. The previous year has brought a conscious realisation to small entrepreneurs and has led to a nationwide expansion of smart management and systems.

1. In recent years, cognitive radio ad-hoc networks (CRAN) have become increasingly popular due to their ability to improve spectrum utilization and enhance wireless communication. CRANs are becoming increasingly popular due to their ability to improve spectrum utilization and enhance wireless communication; security remains a significant challenge. However, security in CRAN remains a considerable challenge, with malicious actors capable of causing disruptions and stealing data. One promising solution to this problem is using blockchain technology to secure CRANs. The paragraph sets the stage for discussing how blockchain technology can help solve this problem.
2. Blockchain technology, initially developed for the cryptocurrency Bitcoin, has evolved into a sophisticated tool for secure and transparent data management. The blockchain is essentially a decentralized, distributed ledger that records transactions in a tamper-proof manner. This technology can potentially transform the security of CRANs by providing a secure and transparent way to manage communication and ensure data privacy.
   1. Spectrum Management: This section explains how blockchain technology can enhance security in CRANs by providing a secure and transparent method for spectrum management. In a typical CRAN, nodes may compete for available frequencies, leading to interference and reduced network performance. However, using blockchain, nodes can reach a consensus on spectrum usage, ensuring each node gets a fair share of the available spectrum. This can help to reduce interference and improve network performance.

For example, imagine a group of devices in a park that want to use the same frequency band to communicate with each other. Without a centralized authority to manage spectrum usage, these devices could interfere with each other and cause communication issues. However, by using blockchain technology, the devices could come to a consensus on which frequency band each device can operate at a given time, ensuring that there is no interference and that communication is reliable.

1. One-way blockchain technology can enhance security in CRANs is by providing a secure and transparent method for spectrum management. In a typical CRAN, nodes may compete for available frequencies, leading to interference and reduced network performance. Using blockchain, nodes can reach a consensus on spectrum usage, ensuring each node gets a fair share of the available spectrum. This can help to reduce interference and improve network performance.

1. Identity Management: This section explains how blockchain technology can enhance security in CRANs by providing a secure and transparent method for identity management. In a typical CRAN, nodes may be vulnerable to spoofing and impersonation attacks, leading to data theft and network disruptions. However, using blockchain, nodes can authenticate each other using public- key cryptography, ensuring that only authorized nodes can access the network. This can help to prevent unauthorized access and protect against malicious attacks.

For example, consider a group of intelligent sensors in a building that are communicating with each other to monitor temperature and humidity levels. Without a secure method of identity management, a malicious actor could spoof the identity of one of the sensors and gain access to the network, potentially stealing data or disrupting communication. However, using blockchain technology, each sensor can be authenticated using public-key cryptography, ensuring that only authorized sensors can communicate with each other.

The business world has seen and felt a huge change since the rise of the Industrial Revolution. Many industry pioneers and business leaders are waiting for the Fifth Industrial Revolution named as Industry 5.0, focusing on collaboration between Revolution, Innovation and Efficiency. Industry 4.0 was in service for the benefit of the industry and finding their limitations since last 10 years by introducing some important technologies like Artificial Intelligence (AI), Machine Learning (ML) Internet of Things (IoT), Cloud Computing, Cyber-physical system and Cognitive computing etc. Industry 5.0 is changing paradigm and brings the resolution since it will decrease emphasis on the technology and assume that the potential for progress is based on collaboration among the humans and machines. As businesses started to embrace Industry 4.0, along came with the Fifth Industrial Revolution, increased human interaction with smart machines for enhancing efficiency. The industrial revolution is refining customer satisfaction by utilizing personalized products. There is also debate of the applications enabled in industry 5.0 like healthcare, supply chain, production in manufacturing, cloud manufacturing, etc.

Real dynamical systems tend to contain individual elements with nonlinear characteristics. Such characteristics correspond to a number of elements:

• limiters, as well as devices with saturation of magnetic characteristics in electronic and electromagnetic systems;
• Rubber parts, vibration dampers, as well as leaf springs in mechanical systems , etc.

Therefore, when studying oscillations in such systems, it is necessary to take into account the nonlinearity and characteristics of individual elements and the features of oscillations inherent in nonlinear systems with such characteristics [13, 30]. The most significant features of nonlinear oscillatory systems are as follows:

• They do not apply the principle of superposition;
• Several equilibrium positions may exist in them;
• Their free oscillations are notizochronous, that is, the frequency of free oscillations depends on the initial conditions;
• They are ambiguous, that is, the results of the solution depend not only on the frequency, but also on the amplitude of the perturbations; it is possible to appear oscillations with frequencies of 2, 3, etc. times lower frequencies of the main oscillations - subharmonic oscillations, as well as with frequencies of 2, 3, etc. times higher frequencies of the main oscillations - superharmonic (ultraharmonic) oscillations.
• The possibility of the appearance of self-oscillatory modes, i.e. non-extinguishing oscillations even in the absence of an active perturbation, despite the presence of dissipative forces.

Global optimization sets itself the mission of identifying the most interesting solutions in the overall search space. But actually, it is only the best of all discovered candidate solutions in the explored search space, which depends, in turn, on initial positions of searching points. It is practically impossible to cover the entire search space of NP-hard problems, in a reasonable time, whatever the method used, since the size of this space exceed the capabilities of all sophisticated algorithms implemented on any powerful computer even parallel ones. That is what justify the increased interest to nature-inspired metaheuristics, currently, based on a strategy of balance between exploitation and exploration, which make their approaches looking like smart. Exploration guarantees that the used algorithm will reach the widest possible extent of the undiscovered areas, whereas exploitation guarantees that such algorithm will search for the best solutions inside the most promising areas, already discovered. Authors study, in this work, different implementations of exploration and exploitation mechanisms utilized in many well-known nature-inspired metaheuristics applied to both uni-model and multi-model benchmarks. Uni-model benchmarks aim to test exploitation while multi-model benchmarks aim to test exploration. Obtained results show the superiority of TSO metaheuristic to find the adequate balance between exploration and exploitation leading it to discover in all tested cases, at least, one of the global optima or one of the best near global optima.

     In 2019, the United Nations announced that over 60 countries had committed to carbon neutrality by 2050. This tremendously accelerated the dynamics for the development of green, carbon-neutral steelmaking technologies. One way to replace the carbon-intensive blast furnace/basic oxygen furnace (BF/BOF) steelmaking route is to use hydrogen-based direct reduction and an electric arc furnace (EAF).

     About 70% of the world’s steel is produced via the BF/BOF route, an efficient but highly carbon-intensive production method. With limited investment cycles left until 2050, the steelmaking industry must decide which alternative technology for the reduction of iron ore to invest in within the next five to ten years.

     One widely discussed alternative to traditional BF/BOF steelmaking is the hydrogen-based direct reduction of iron ore and EAF. Most of the current pilot projects focus on applying shaft furnaces for direct reduction with hydrogen. However, applying this method would generate the need for several hundred million tons of additional high-quality DR-grade pellets annually, with the associated impacts on pellet availability and prices.

     An alternative is hydrogen-based direct reduction using fine ore instead of pellets. Metso Outotec’s Circored technology is the only process for iron ore reduction based on 100% hydrogen that has proven its functionality and performance in an industrial-scale demonstration plant.

     Circored technology is flexible in its production setup. Besides merchant cold HBI (hot briquetted iron), which can easily be shipped, hot and cold DRI (direct reduced iron) can be produced and directly linked to EAFs and BOFs as a substitute for hot metal and/or other virgin iron units. This guarantees the production of the high-quality steel products that have been traditionally the strength of integrated steel plants.

     In this paper, the principle of the Circored process and the results of the demonstration plant operation are described, along with the possible role of the Circored fine ore direct reduction process in the industry’s transition toward green steel.

This research focuses on optimum usage of industrial waste in soil stabilization. Shear strength alteration happens in subsoil due to environmental fluctuations or seismic events that are generally observed in hilly areas with unsupported backfills. This problem becomes worst in the case of problematic soil that causes collapse or swelling followed by shrinkage in contact with water due to the high anisotropic nature of the subsoil. The cyclic behavior of various problematic soils under transient loading directly incorporates the economic loss and human lives. The present experimental work has briefly described the suitability of using rice husk ash (RHA) in soil stabilization and reducing the dumping of toxic waste responsible for environmental pollution. In place of common stabilizer units such as fly ash and pond ash, we use a cheap stabilizing agent which has no use in soil improvement in past as single unit. RHA is used as a chemical stabilizer as it contains high percentage of silica. If the soil has a larger fraction of clay mineral, then RHA (produced by controlled incineration ~400-500°C) mixed soil in different proportion (4 and 6% by weight of soil sample) performed differently in serviceability and workability tests on soil sample like UCS, modified proctor test, CBR, Atterberg’s limit, permeability, consolidation test, etc. Excellent results were obtained at 6% optimum dosage of RHA in locally available laterite soil (inside NIT Agartala campus) from NE part of India.

The use of turbochargers nowadays is growing rapidly. However, compliance with stricter environmental regulations for internal combustion engines and the need to reduce fuel consumption are emerging in the above-mentioned group of components. The documentation describes the analytical determination, measurement options and the impact on the turbocharger of axial loads, also known as axial loads, in various publications. The resulting axial force, due to the narrow axial tolerance ranges used in the turbocharger, can cause damage to its structure above a certain level. To avoid this, a so-called axial bearing is installed which, together with the damping effect of the surrounding oil film, prevents excessive rotation of the rotating part in the axial direction. However, under certain conditions, the presence of the oil film between the rotating unit and the stationary axial bearing may be eliminated by heavy stress, so that not only significant friction, but also damage to the bearings and ultimately, the turbocharger may occur. In order to avoid injuries and reduce the friction losses of the charger, it is necessary to define the stresses present here as accurately as possible and to simulate the effect of changing conditions. The purpose of this document is to process the methods and knowledge of this publication in various publications, and to assess further research options that model the impact of the stress caused by EURO 7 and further environmental standards.

Financial Management assists ways to attain the goals and objectives within the academic institutions. People understand the key features of the financial management that includes the organisation, transparency and awareness about the features that operate the institution ethically and legally. Managing the academic finance is effectively a complicated series of monthly and annual administration of finance at different levels. The success of academics initiates the momentum for the flow of funds within and outside the Academic Institutions. However, this is not merely by chance. It requires rigorous designing and executing of the initiatives for and by the key stakeholders. This is the normal misconception that the financial management of the corporate sector organizations is difficult than the Academic Institutions. In general, the versatility of the financial management of the Corporate Sector Industries could be more but depth, uncertainty and complexity of the financial management of Academic Institutions is at par with that Corporate Sector Companies. In both the sectors, the Human Resource element makes the management more dynamic and challenging. In Academics as well, the employees are determined, ambitious and obsessive as well. This calls for the ability to push back and win their support. Management offers opportunities and resources to the employees and other stakeholders. However, there is an impact of the psychology and mind-set on the financial management. All the Stakeholders are crucial for the Academic Institutions even though the financial management gets affected to a large extent by the Top Management and their decision making.

Open-source software has pumped up a revolutionary change in the way the software industry functions. But it has also increased the concerns related to software licensing issues, when we receive, make copies or distribute any software. Generally, a proprietary software license agreement clearly mentions about its transfer of rights to use, modify, copy, distribute or derivative works. But due to a variety of open license standards and their varied impact, sometimes confusion arises for volunteers/open source developers to choose the proper licensing for their software code. In this context, a clear understanding is necessary about the open source licensing issues for the FOSS developers, enthusiasts and volunteers [1].

The growing application of AI in drug development, medical imaging, and customized medicine is fueling this increase. A estimated CAGR of 41.1% for the financial services industry from 2021 to 2026 indicates that it will likewise be a significant adopter of AI. In this sector, artificial intelligence (AI) technologies are employed for fraud detection, risk management, and customer service. There is a lot of potential for both beneficial and harmful effects on society in the quickly expanding fields of AI's impact on the labor market, facial recognition, deepfake, and cyberattack. As AI develops, it is crucial that creators, decision-makers, and the general public collaborate to make sure that new technologies are created and applied in a way that is open, equitable, and helpful to all.

Nowadays, the different custom power topologies are being competed in the utility market and also, their impact is compared on the basis of shunt compensation. By keeping the improved design of the DSTATCOM in the power system, there are critical issues to maximize the advantage of the existing device. Also, possible synchronization between different compensators for the purpose of achieving better PQ solutions is studied. Still, Power engineers and scientists are looking forward to launching a new compensator to strengthen its filtering competency and have a competitive edge on PQ issues. Depending on the application, the inverter requires specific features such as voltage gain, size, efficiency, cost etc. Voltage source inverters (VSIs) and current source inverters (CSIs) are two well known inverters widely used in various applications. Since VSI reduces the voltage level where as CSI increases the voltage. But both have a limit in compensation capability . The above drawbacks of VSI and CSI were solved by the impedance source inverter (ZSI) family. The X-shape ZSI consists of two inductors and two capacitors. Its configuration cause to increase its boost capability in one stage through a shoot-through state. In other words the upper and lower switches of its leg are turned on simultaneously, which is impossible in the traditional VSI .

Major cities are highly endangered from thefts in a range of ways, such chain robberies, robberies committed by persons inside stores, and home invasions. These residential crimes take place by breaking in via the locked doors. It is sometimes possible to prevent murder of an owner during a late-night heist by having cops patrol the area at night and taking other security measures, according to state police. However, this strategy can't stop home invasion robberies because authorities are unable to search every single house. A number of modules, including Auto-Configuration and Management, Communication Protocol, Auto-monitoring and Control, and Objects Security Systems, are included in the proposed generic framework. The proposed generic framework comprises various modules such as Auto-Configuration and Management, Communication Protocol, auto-monitoring and Control, and Objects Access Control. The architecture of the new generic framework and functionality of various modules in the framework are also presented. The proposed generic framework is helpful for making every house as smart house to increase the comfort of inhabitants with security. Each of the components of generic framework is robust in nature in providing services at any time. The components of smart home system are designed to take care of various issues such as scalability, interoperability, device adaptability, security and privacy. The proposed generic framework is designed to work on all vendor boards and variants of Linux and Windows operating system.

This paper aimed at analysing the current state of methods of increasing methane generation during treatment of organic sewage sludge. The authors considered the theoretical principles of biogas production and the main directions of intensification of methane fermentation processes. A chemical study of sediments produced at sewage treatment plants in the city of Kharkiv, Ukraine, showed that the C/N ratio in the investigated excess activated sludge is 4-5, in the mixture of primary and secondary sediment - 5-6, in sediment from sludge sites - 6 -10, which is significantly less than the ratio of 20:1, which limits the negative impact of increased nitrogen content in organic substrate for methane fermentation. The directions for rising speed of the first phase of sediment fermentation and directions for increasing methane output during fermentation of a complex organic substrate have been determined. The promising technologies of adding organic substrates, richer in carbon compared to sewage sludge, have been noted. This solution will not only make it possible to improve productivity of fermenters, but at the same time resolve the issue of organic waste management.

A highly nonlinear relationship exists between complex driving conditions, external influencing factors and vehicle energy consumption. Considering the spatiotemporal characteristics of vehicle operation, the significant feature parameters are extracted to improve the accuracy of vehicle energy consumption prediction. In this paper, an electric vehicle energy consumption prediction method that integrates real vehicle operation data and machine learning methods is proposed. Based on a large amount of real vehicle operation data, data cleaning and data integration methods are used to divide different kinematic segments. The key features of vehicle operation are extracted from the kinematic segment, and the correlation coefficient analysis is used to screen important feature values. Based on the XGBoost algorithm, the vehicle termination SOC prediction model is established to further obtain the results of the vehicle energy consumption. Through real vehicle operation data verification, the energy consumption prediction error within 0.04kWh, the results indicate that the proposed method gives out high accuracy.

Single directive beam Antennas suffer from a sufficient number of bottlenecks. Alternatively a multi-beam Antenna(MBA’s) where Antennas work independently and concurrently to achieve High Gain and Beamforming in the RF domain can prove as a candidate solution to present day Single Beam Antennas as they serve as key enablers for Massive-MIMO configuration, a breakthrough towards the conventional MIMO where a very large number of service Antennas operate fully coherently and adaptively. Here MBA’s operating in the mm-Wave band have attracted much interest and have been rigorously investigated here. With the demanding requirements of 5G which prove as advantageous solutions to today’s spectrum shortage at conventional cellular frequencies. Since it is simultaneously difficult to obtain High Gain and Wide coverage , Quasi-Conical Beam Antennas have been proposed as candidate solution to today’s problems. Such Antennas produce High Gain pencil beam which electrically scan along a cone to provide enormous special diversity in the time domain. The concept is based on the development of a novel Fabry-Perot-Fermi Antenna with wide Angle steering capability to produce Fan-Beam in the azimuth direction along a cone. Furthermore they are different from conventional MBA’s in the sense that no additional beamforming network like Buttler-Matrix or Rotman-Lens is required to produce the multi-beam and FP Antenna itself acts as the radiator. Also the addition of an additional beamforming network increases complexity in terms of Size and Cost. Initially an Array of 3-FP Antenna elements were arranged in a back-to-back tri-element configuration or CONBA-(Conical Beamformed Array) orientation to form diversity combination in the time domain by switching each individual elements for a time period to cover the enormous angular Spatial range. Simulation and measurement results show that the S-parameter is below (S₁₁ < -10dB) at an operating bandwidth from (10.17GHz-19.92GHz) and a wide Impedence Bandwidth around 64.805% illustrating a Wideband nature. The novelty of the proposed work is that only 3-FP Antenna elements can cover the entire 360ο range in the azimuth plane(φ-plane) which is an improvement over other proposed works where 8 or more than 8 elements cover the entire range. For this enormous Parametric studies have been performed to achieve such a performance improvement. Also the configuration of FP Antennas have wide Scan Angle capability of 50^ο(8^ο - 58^ο) in the elevation plane(θ-plane) which is achievable far better. These characteristics make the configuration suitable for UAV and Space Applications.

Over the past few years, the use of electronic health records (EHRs), wearable devices and health apps has grown in popularity. Due to the abundance of collected and integrated data, self-management of health becomes more practical. Among the challenges facing the current health system are intelligent homes and intelligent workplaces made possible by the Internet of Things. The Web of Things (WoT) is a subset of the Internet of Things that aims to connect everyday things to the Internet and manage interoperability. Furthermore, collaboration of health data with data from various devices at home and at work, as well as open data on the Internet, is critical for successful and accessible health self-management. Unfortunately, shared health data may be untrustworthy for a variety of reasons. Uncertainty can be caused by heterogeneity, incompleteness, unavailability, and data inconsistency. To address the problem of health data uncertainty, we provide a probabilistic approach for composing uncertain Health Connected Data and computing the probabilities to deliver the final degree of uncertainty. We also present a method for parsing typical WoT objects into a new programmatic form that mimics the uncertainty of health data. Using a health care use case, we show how our technique successfully integrates uncertain health data with home, work, and sport environment data for the WoT domain.

A new type of wind turbine has been created called the bladeless turbine, which uses a completely new type to capture wind energy, as it works with a minimum of moving parts to generate electric current using the vibration produced by the wind. In this chapter, numerical modeling of airflow around a two-dimensional cylinder was made and compared with the reference values to ensure the correctness of the program used, and then the three-dimensional cylinder was studied and the numerical study expanded to include several cases. Where the study was conducted on 5 different shapes of the mast by changing the angles of inclination of the cylinder under boundary conditions T=288.16 K, P=l atm, V = 0.0003 m/s and studying the effect of model dimensions on the results of the modeling process by comparing the pressure diagrams around the studied shapes in order to ensure that the results are within the least relative error. The results also showed that with increasing the angle of inclination of the cylinder, a lower pressure drop was obtained. Numerical modeling of the airflow around the bladeless wind turbine was also made according to two cases, the first case when the same boundary conditions V =0.0003 m/s, T = 288.16 K, P = l atm, the second case at reference boundary conditions V = 3 m/s, T = 300K, P = l atm, Using a regular mesh and hexahedron, the density of the used mesh has been modeled, and then reviewing the effect of the used perturbative model on the results, choosing the perturbative model best suited to the studied case, and comparing it with the reference case.

International students have greater difficulties navigating a variety of academic and social contexts than host nationals. Language-related issues were among the most often cited difficulties by students studying abroad. Many students who study abroad and rely on language to navigate have a tough time learning a new language. If asked to identify the most significant influence on language learning, most teachers and students would likely name motivation. Teachers of foreign languages frequently use the term "motivation" when describing successful or failed students. Nonetheless, there is no doubt that motivation is the most complex and difficult challenge confronted by language learners, particularly in this digital age. Numerous research on the efficiency of computer-assisted language learning have been conducted in recent years, and the literature on the psychology of language learning is vast. Regarding the psychological aspect of a mobile-assisted language-learning environment, relatively little research has been undertaken. In addition, few research have directly examined the attitudes of international students regarding the usage of mobile devices to motivate their foreign language learning. The purpose of this article is to investigate Chinese over-seas university students' use of MALL applications to motivate foreign language learning in Germany. The study evaluated whether and how perceived tools or activities can affect learners' motivation to acquire foreign languages in informal settings. In addition, the reasons why mobile devices motivate language use and specific types of motivation are investigated.

Some aspects of the application of probabilistic methods in the problems of dynamics, strength and reliability of rail crews are consistently outlined. Methods for generating random perturbation and solving problems about random oscillations of crews with linear and nonlinear characteristics of spring suspension are considered. It is shown that random oscillations of nonlinear systems are non-stationary and to determine their probabilistic characteristics it is necessary to apply the averaging procedure for a set of implementations.

The semi-automatic car parking system has been used in many cities across the world due to its many benefits, including its tiny model, compaction, need for less space, and speedy construction. The car parking system solution may hold the key to addressing the parking needs of urban areas since it has specifications that are appropriate to the needs and characteristics of HoChiMinh City. However, in terms of sustainable and aesthetically pleasing urban development, choosing the best location to place the parking model is difficult. Therefore, this research aims to determine the selection of criteria affecting the location of semi-automatic car parking criteria based on a Multicriteria Decision Making Model (MCDM). The contribution of this study is a set of guidelines with four primary criteria and eighteen sub-criteria to assist private businesses and local management organizations choose the best location for semi-automatic parking to maximize efficiency and toward urban sustainability.

In view of the poor evaluation effect of MOOC learning efficiency, this study proposes an intelligent evaluation method of MOOC learning efficiency based on Kirkpatrick's model.

Then optimize the intelligent evaluation steps of teaching efficiency. The experimental results show that this method has high practicability and accuracy in practical application, and can fully meet the research requirements.

So what is the Russian engineering school? Why exactly is it necessary to restore it? Among the many publications on the founding of 30 engineering schools in Russia, there is almost no explanation of this phenomenon [1]. Perhaps this is due to the fact that historians of science know more about the “Russian engineering school”. Experts in the history of science and Higher Education in Russia are in solidarity in their main assessments and conclusions [2]. According to their opinion, from the birth of engineering education in Russia under Peter the Great and up to the present day, the engineering school has been preparing true engineering élite, who were capable of resolving the most challenging issues of ensuring security and technological development of the country. Since the end of the 19th century it has achieved such a level that it has always been a role model for others to follow. For a better understanding of the Russian engineering education, it is necessary to look at the main periods of its formation and development [3].

The Forces between two charges are one the four fundamental forces that keep the world together Indeed when a single photon is emitted, it spreads over a system, the intensity decrease by square law of the distance which compliant with conservation of energy. A changing magnetic field creates an electric field, and a changing electric field creates a magnetic field, and an accelerating electric field creates an accelerating magnetic field. Electric lines are modeled for visualizing the effect in space of electrostatic forces that occur two or more charged particles. Maxwell equation provides a Mathematical model for electric, optical and radio technologies such as power generation, electrical motor and wireless communication. Unfortunately, Maxwell’s equation requires some advanced techniques which lie well beyond the understanding of this paper. The derivation of maxwell’s equations is approach established for the time -dependent from static laws, The variation of electrical fields and magnetic field and Faraday’s law can be derived without any assumption relativistic.

     The Outcome-based Education (OBE) introduce in the United States since 1994. Many countries started onwards for universities also implementing in public schools system since 2008.

     In Outcome-based education, teachers are the facilitators, rather than lecturers. In OBE teachers guide students through learning, hands-on, curricular activities & interactions to guide student engagement with new study material. Also motivate & encourage the application of developing knowledge and skills through the students.

     The concept of green supply chain is fast gaining momentum, because of the environmental concerns. The 6 R’s namely Reduce, Reuse, Recycle, Rethink, Refuse, and Repair are securing importance. A new concept of remanufacturing is also coming up Due to limited availability of natural resources, there is constant demand to reduce consumption [1]. The manufacturers are constantly taking account of the environmental concerns while designing supply chains. The green supply chain management (GSCM) primarily emphasizes on reducing the waste generation and reusing the waste. GSCM is “integrating environmental thinking into supply chain management, including product design, material sourcing and selection, manufacturing processes, delivery of the final products to the consumers, and end-of-life management of the product after its useful life” [2].

     Considering the issues of human interaction with the environment, there is often a need to know the permissible limits of impacts under which the natural-technogenic system does not leave a stable permissible state. This applies to the most diverse areas of scientific and practical activity in natural or human-modified environments. For example, in geotechnics - it is necessary to know the limits of static and dynamic loads on soils, resistance to shear and other stresses; in hydrogeology - to additional infiltration feeding of groundwater, pressure gradients; in thermal physics - resistance to temperature effects. That is, it is necessary to assess the permissible limits in a wide variety of areas of physical interactions in the "human - environment" system.

     The need to move away from fossil energy sources has never been so strong. One of the technologies under the spotlight in recent years is certainly that of Fuel Cells (FC). Direct Methanol Fuel Cells (DMFC), Solid Oxide Fuel Cells (SOFC) or Molten Carbonate Fuel Cells (MCFC) represent different developing paths of this technology, but they all share a couple of benefits with respect to other energy conversion devices: they have no moving parts and a quite simple working principle. But how can we push forward the development of FCs?

Cow leather, an animal product, is a common material. Despite being robust, it raises moral, social, and environmental concerns. The world is warming up, plant habitats and plant origins are being destroyed, artificial colours have an adverse effect on the environment and human health, and animal products and hair are utilized to make various types of leather and pricey fashionable clothing. Vegan leather, which was produced by recreating leftovers or growing living cells, may be a recent innovation for the manifesto on sustainable fashion. Another biomaterial manufactured without fleshing any animal is environmentally friendly and animal free leather, often known as "vegan leather" or "artificial leather". As an alternative to cow leather or other animal leather, the creation of vegan leather using a symbiotic culture of bacteria and yeast (SCOBY) can be investigated. There is currently few research on the several substrates that can be used to create vegan leather using this process. In order to provide plant-based vegan leather, this paper used a variety of plant-based substrates, including SCOBY and kombucha tea. To sum up, this substance might also be thought of as a potential leather substitute for use in leather accessories like handbags and upper shoe soles.

The final outcome of utilizing the cloud-based COSTA QDA and technique culminates in presentation of methodologies that demonstrates how large volumes of textual data, also known and referred to as “big qualitative data” may be transformed to structured, coherent, meaningful and timely decision-making enablers.

     Manufacturing components and parts for a specific application are generally fabricated by traditional methods followed by industrial standards. With the modern era of machining components new materials, composites and alloys have also been developed for particular applications having desirable and required properties. Boron steel is one such material being used in manufacturing industries for agricultural spades, knives, blades, etc. in its raw form. In the present work, boron steel's properties and chemical composition have been compared when it is heat treated. It was observed that the working life span has been increased effectively and efficiently. This has also been verified using ANSYS.

     Bird's nest is a common defect in transmission line, which seriously affects the safe and stable operation of the line. This paper presents a method of bird's nest hazard level identification based on improved yolov5 and location constraints, which solves the problem of bird's nest multiple identification and hazard level classification. We integrate GhostModule and efficient channel attention (ECA) to design a lightweight attention mechanism convolution module (LAMCM). The original yolov5 is improved by using LAMCM and adding a prediction head, which improves the detection ability of small targets and alleviates the negative impact of scale violence. We only identify the bird's nest on the panorama of Unmanned Aerial Vehicle (UAV) patrol, and classify the hazard level of the bird's nest according to the location constraints of the bird's nest and insulator. Experiments on coco dataset and self built transmission line dataset (TL) show that our algorithm is superior to other commonly used algorithms. On the COCO dataset, our algorithm achieved 49.1% AP at a real-time speed of ~79FPS on Tesla V100. On the TL dataset, the recognition effect of our algorithm on towers, insulators and bird nests has improved to varying degrees compared with the original yolov5. In particular, the recall rate of bird nest identification for three hazard levels has increased by more than 3%. The average recall rate of bird nest hazard level identification is 93%, and the average accuracy rate is 93.5%.
