Full textAbstract:
Throughout preparations for the Sydney 2000 Olympics, there was substantial discussion of a range of technological innovations in sport. On the one hand, performance-enhancing drugs have been rejected as ‘unfair’ or ‘unhealthy’ whilst other technologies have been welcomed with little critique. The debate around drugs in sport and Fastskin bodysuits exposes key elements and contradictions within dominant discourses of sporting performance. At the same time that most athletes and administrators were arguing that equality of access by all Australian team members was the key factor in determining whether Australian swimmers should use bodysuits, other athletes clearly recognised the potential criticism that these suits represent some sort of ‘unnatural’ body enhancement. The issue of performance enhancement was effectively isolated from debates around performance-enhancing drugs by the distinction between the ingestion of drugs and the wearing of suits. As such, the use of the Fastskin suit was depicted as a temporary and function-specific enhancement of the body's natural’ ability and form, rather than a complete molecular transformation of the body — and therefore ‘unnatural’. In this debate, the Fastskin bodysuit and its performance-enhancing potential are presented and legitimated as an acceptable application of human scientific endeavour to the improvement of athletic achievement.

A computational clothing design tool is used to examine the effects of different clothing design features upon performance. Computational predictions of total heat and mass transfer coefficients of the clothing design tool showed good agreement with experimental measurements obtained using a sweating thermal manikin for four different clothing systems, as well as for the unclothed bare manikin. The specific clothing design features examined in this work are the size and placement of air-permeable fabric vents in a protective suit composed primarily of a fabric-laminated polymer film layer. The air-permeable vents were shown to provide additional ventilation and to significantly decrease both the total thermal insulation and the water vapor resistance of the protective suit.

Full textAbstract:
In recent times, there has been a surge in popularity for Software-defined networking (SDN) due to its ability to centralize network management, resulting in greater flexibility and agility. SDN architecture relies heavily on SDN controllers, which play a significant role in controlling and managing the network. However, with a wide range of SDN controllers available on the market, selecting the ideal one can be a daunting task. To assist with this challenge, this article conducts a comparative analysis of several renowned SDN controllers, such as OpenDaylight, Floodlight, Ryu, and ONOS. The assessment is based on two key criteria: performance and functionality. Performance metrics include packet forwarding speed, control plane latency, and memory usage. In contrast, functionality metrics include network virtualization support, security, and scalability. Our evaluation indicates that there is a significant variation in the performance and functionality of the controllers, with some controllers excelling in specific areas compared to others. For example, OpenDaylight had the highest packet forwarding speed, while Ryu exhibited the lowest control plane latency. Concerning functionality, Floodlight presented the most comprehensive security features, whereas ONOS demonstrated the best scalability. Overall, this article presents a thorough evaluation of SDN controllers’ performance and functionality, which can guide network administrators in choosing the most appropriate controller to suit their specific requirements.

Full textAbstract:
In November 1990, the Texas Attorney General filed a lawsuit against The Methodist Hospital System, alleging that it had failed in its duty to provide enough charity care to poor people. The state claimed that the hospital provided significantly less charity care than the hospital reported; it then filed the suit in an effort to require specific performance—that is, to compel the hospital to provide greater amounts of charity care in the future. The case focuses on the amount of charity care provided before the suit, the economic value of the tax exemption provided to the hospital because it is a not-for-profit (NFP) hospital, and the responsibilities of the hospital given the expectations of society. The case also brings into sharp relief the value of having tax-exempt status and the social and political expectations that accompany the exemption. In addition, the case raises ethical questions concerning these issues, as well as issues involving the financial reporting of the entity and management perquisites.

A patient-specific implant is a designed implant that considers the needs of a specialized patients condition. In several surgical cases, the implant design needs to be adjusted based on the patient bones surface to suit the bone morphometry. This study aims to conduct the finite element analysis to investigate the stress distribution alongside the plate to consider clinical implementation. A bone plate has been designed following an adult pelvic bone shape for the pelvic fractures clinical case management. An FEA was accomplished to analyse the implant designs performance and estimate the installations clinical failures before the manufacturing process. The FEA calculation achieved the highest number of von misses stresses (VM) on the pelvic bone plate by 3.616 MPa. The obtained VM number on the simulation is smaller than the yield strength of Ti6Al4V. It concludes that the customized iliac plates design using Ti6Al4V can have excellent mechanical strength and can withstand the loading. Additional similar simulation using another software strengthen the results.

The aerodynamic design of turbochargers is described, covering radial compressors and turbines and also axial turbines. The paper concentrates upon those aspects that are peculiar to turbocharger design, including the approach adopted, and highlights the importance of company-specific empirical data. Turbochargers have to be physically adaptable to suit many different sizes of engine, with a great variety of operating duties. The need for turbochargers to achieve the highest obtainable performance at the lowest cost while maintaining durability levels comparable with the engine contributes to the design challenges that are discussed.

Full textAbstract:
Continuum robots have often been compared with rigid-link designs through conventional performance metrics (e.g., precision and Jacobian-based indicators). However, these metrics were developed to suit rigid-link robots and are tuned to capture specific facets of performance, in which continuum robots do not excel. Furthermore, conventional metrics either fail to capture the key advantages of continuum designs, such as their capability to operate in complex environments thanks to their slender shape and flexibility, or see them as detrimental (e.g., compliance). Previous work has rarely addressed this issue, and never in a systematic way. Therefore, this paper discusses the facets of a continuum robot performance that cannot be characterized by existing indicator and aims at defining a tailored framework of geometrical specifications and kinetostatic indicators. The proposed framework combines the geometric requirements dictated by the target environment and a methodology to obtain bioinspired reference metrics from a biological equivalent of the continuum robot (e.g., a snake, a tentacle, or a trunk). A numerical example is then reported for a swimming snake robot use case.

This research paper undertakes a comparative analysis of design guideline recommendations derived from the Mahoney Table across five diverse and distinctive climates according to the Koppen classification of world climates. Mahoney Table is a key analytical tool which aids architects in designing structures that are in harmony with local climates. By leveraging the insights gleaned from the Mahoney Table, architects can tailor design strategies to suit the specific climatic characteristics of each region. This approach not only optimizes building performance but also reduces reliance on mechanical heating or cooling systems, thereby promoting sustainability and environmentally conscious design practices

Full textAbstract:
During the COVID-19 pandemic, the provision of appropriate protective clothing for medical staff who must continue to perform their duties at this period is of particular importance. Physiotherapists are not allowed to suspend working during this time either, and the specifics of their work is close contact with the patient within various movements during the therapy process. Inadequate (intended for general use) protective clothing affects work capacity in the aspects of movement restriction, thermal comfort and thereby increasing energy consumption. For the design and supply of personal protective equipment (PPE) and protective clothing of the best possible quality, PPE should be explored in a systemic approach (holistics) to assess anthropometric fit and ergonomics, material properties and thermal performance. This study investigated anthropometric characteristics of target group representatives; sizing, fit and design flaws of protective suits for physiotherapists; provision of mobility in the protective clothing of physiotherapists; the protective suit fabric layer interaction with the human body and the importance of subjective evaluation of fit and ergonomics of PPE (made by specialists and wearers). The results of the study promote the usage of objective knowledge of anthropometry and ergonomics as well as subjective assessment findings in the development of protective suits for physiotherapists.

Popular music comes in a multitude of styles. This creates problems in offering decent popular music education, which concerns the stylistic vocal performance of popular music. Therefore, there is a need to examine the training curriculum provided currently. The research problems studied have adhered to the research questions for the study. At the same time, a conceptual framework for examining the functionality of the training curriculum encompasses the theoretical supports of four-dimensional matrixes and five principles of curriculum development. The case study can be carried out based on the conceptual framework to examine the training curriculum development of stylistic vocal performance education to ensure that the talents trained suit the market and music industry. The conceptual framework provides a structured approach for analysing and understanding the problem, and the case study method allows for an in-depth examination of a specific real-life situation or instance. By combining these two methods, the study can provide valuable insights and recommendations for improving the curriculum and training process.

Abstract Harnessing anionic terpolymerization of styrene, isoprene and butadiene to a degree where one can achieve simultaneous control of composition, microstructure and sequence distribution results in a unique family of elastomeric materials. We now can tailor-make elastomers having diverse viscoelastic responses to suit specific tire applications, in particular, those required for high performance tires. Furthermore, we have demonstrated unique morphologies attainable for SIBR ranging from lamellar to spherical. Such morphologies were reported previously for soft/hard block copolymers, i.e. SBS and SIS, but not for soft/soft systems. It is our contention that this will further contribute to our understanding of the relationship between morphology and cured physical properties.

Full textAbstract:
The Wissler human thermoregulation model was augmented to incorporate simulation of a space suit thermal control system that includes interaction with a liquid cooled garment (LCG) and ventilation gas flow through the suit. The model was utilized in the design process of an automatic controller intended to maintain thermal neutrality of an exercising subject wearing a liquid cooling garment. An experimental apparatus was designed and built to test the efficacy of specific physiological state measurements to provide feedback data for input to the automatic control algorithm. Control of the coolant inlet temperature to the LCG was based on evaluation of transient physiological parameters that describe the thermal state of the subject, including metabolic rate, skin temperatures, and core temperature. Experimental evaluation of the control algorithm function was accomplished in an environmental chamber under conditions that simulated the thermal environment of a space suit and transient metabolic work loads typical of astronaut extravehicular activity (EVA). The model was also applied to analyze experiments to evaluate performance of the automatic control system in maintaining thermal comfort during extensive transient metabolic profiles for a range of environmental temperatures. Finally, the model was used to predict the efficacy of the LCG thermal controller for providing thermal comfort for a variety of regimens that may be encountered in future space missions. Simulations with the Wissler model accurately predicted the thermal interaction between the subject and LCG for a wide range of metabolic profiles and environmental conditions and matched the function of the automatic temperature controller for inlet cooling water to the LCG.

A high-performance photonic reservoir, which utilizes the injection locking effect in a highly multimodal semiconductor laser, has been developed. This innovative design allows for fully parallel and high-bandwidth operation. The output of this system is projected in space and imaged onto a digital micromirror device, which provides a readout and facilitates the hardware integration of programmable output weights. By using a highly multimodal semiconductor laser, the injection locking effect enables a large number of modes to be simultaneously locked to the injected signal, resulting in high dimensionality of the reservoir, reducing the computational time and complexity. The use of a digital micromirror device provides a flexible readout, allowing the output to be programmed to suit a range of applications. The hardware integration of programmable output weights enables the system to be optimized for specific tasks, improving performance and reducing power consumption.

Purpose The purpose of this study is to investigate how motivation – gained by understanding the purpose of specific cyber-oriented tasks – coping strategies and level of physical conditioning can affect cognitive abilities amongst cyber officer cadets. Design/methodology/approach Two cognitive tests (2014 and 2015) and coping strategy questionnaires (2015) were conducted during an annual military exercise involving increased levels of stress and hardship (physical and cognitive) over a sustained two-week period. Findings Motivation – gained by task explanations – and the conscious use of the “control” strategy can have a positive effect on individual performance in cyber tasks. Research limitations/implications The participants were all young adults with higher-than-average levels of physical fitness. From the outset, all participants were highly motivated and disciplined having entered cyber officer training after successfully completing a thorough selection process. Practical implications The results of this study are to be better implemented to the activities at the military academy. Social implications The closest civilian occupational equivalent is a computer network operations (CNO)-operator. The findings could be implemented into their daily work routines. Originality/value Cognitive tests used in this study are based on recognized general cognitive tests. However, modifications were made to suit the cyber task context, making the test original. The cyber officer is a contemporary concept currently lacking research.

Full textAbstract:
Most academic researchers use the academic information system when they want to write a reference, such as a related research for a paper. Specific classification rules are applied based on vast amounts of data and the latest references to classify and search keywords. Meta information is designed for specific classification rules and search results are restructured. The search results can be classified and rearranged to suit academic research paper keywords by applying the restructured classification system and the LDA-based topic modeling technique. To implement this, the ElasticSearch classification method and topic-based LDA model were applied to extract the characteristics of academic papers in this study. Stable topics that could detect topic estimation and keyword search results within the minimum time were extracted to classify the paper search results. In addition, by analyzing the distribution of document weight among topics, the system performance was proven to be excellent.

In the work, a study was made of harmful production factors affecting a worker in the dairy industry. It established that in the modern production of dairy products, high-performance technological equipment is used, the operation of which leads to the appearance of hazardous and harmful production factors. Noise is not the last among them. The degree of negative impact of noise on people depends on its frequency range, intensity, duration of action and the nature of the personnel work. The zones of the greatest non-specific effect of noise on a person are identified. It is established that the operator of the dairy industry is in close contact with the process equipment. The most suitable solution for protecting personnel from noise is the use of personal protective equipment. The article evaluates the noise impact on the operators of the dairy processing industry of the Republic of Mordovia within the framework of a special assessment of working conditions using the Assistant noise meter of the first accuracy class. Exceeding the noise level is observed at all the same type of workplaces. To protect workers from increased noise, a noise protection suit was developed, consisting of a jacket, and trousers. Experimental studies of the noise-protective properties of this suit were carried out at the Department of Life Safety of FGBOU VO «Moscow State University nabbed after N.P. Ogarev» with the use of modern reverberation chamber BZD-16. This suit differs from the standard overalls in the presence of additional noise-protective inserts that allow to protect the most vulnerable parts of the worker body from the aggressive effects of noise.

This paper introduces Energy-Product-Service Systems (EPSS) to overcome the issues in the liberalized energy market. Currently, conventional energy services are highly commoditized, thus eroding their competitiveness in a liberalized energy market. In addition, customer benefits from the current system are hard to analyse, because it is difficult for customers to observe the quality of the results of energy consumption. EPSS incorporates energy sector with other related sectors to design and deliver immediate result of energy usage that suit to customer’s specific needs is expected to provide better performance than current system. However, EPSS service design and implementation involve high risk and performance uncertainties. Therefore, this study proposes a method to design and to evaluate EPSS and compare its performances with energy product/service performance in current system through Simulation-Based Design (SBD). SBD is used to construct EPSS service considering stakeholders’ interest and to evaluate the service performance, by simulating alternative scenarios in order to seek conditions that are expected to fulfil stakeholders’ requirements. In the proposed analysis, three service features, that is, service consumption management, operational system design and electricity supply management are introduced and used to develop EPSS alternative design for space-heating service. Afterwards, customer satisfaction and the company’s benefit for each service scenarios are simulated and compared with the performance of the current system. In this context, EPSS design that includes operational system design and electricity supply management results in better benefit for all stakeholders.

Abstract. The use of flexible hydrological model structures for hypothesis testing requires an objective and diagnostic method to identify whether a rainfall-runoff model structure is suitable for a certain catchment. To determine if a model structure is realistic, i.e. if it captures the relevant runoff processes, both performance and consistency are important. Performance describes the ability of a model structure to mimic a specific part of the hydrological behaviour in a specific catchment. This can be assessed based on evaluation criteria, such as the goodness of fit of specific hydrological signatures obtained from hydrological data. Consistency describes the ability of a model structure to adequately reproduce several hydrological signatures simultaneously, while using the same set of parameter values. In this paper we describe and demonstrate a new evaluation Framework for Assessing the Realism of Model structures (FARM). The evaluation framework tests for both performance and consistency using a principal component analysis on a range of evaluation criteria, all emphasizing different hydrological behaviour. The utility of this evaluation framework is demonstrated in a case study of two small headwater catchments (Maimai, New Zealand and Wollefsbach, Luxembourg). Eight different hydrological signatures and eleven model structures have been used for this study. The results suggest that some model structures may reveal the same degree of performance for selected evaluation criteria, while showing differences in consistency. The results also show that some model structures have a higher performance and consistency than others. The principal component analysis in combination with several hydrological signatures is shown to be useful to visualize the performance and consistency of a model structure for the study catchments. With this framework performance and consistency can be tested to identify which model structures suit a catchment better than other model structures.

Full textAbstract:
In task-based language teaching (TBLT), defining and manipulating the complexity of language tasks has been claimed to be of crucial importance, in view of sequencing tasks in a task-based syllabus, manipulating tasks to meet specific learners' needs, and assessing language learners' current level of language proficiency. The theoretical literature and empirical research on task complexity has recendy expanded, but much of this work fails to take into account the multiple dimensions that affect task complexity. For one, in authentic, truly functional task performance, key features of the social setting in which tasks are performed, and interlocutor-dependent variables (such as their shared knowledge and experiences) influence actual task complexity. Since in real life interlocutors reinterpret tasks to suit their own needs, motivations and purposes, and dynamically tune the complexity of their performance to the ongoing conversation and negotiation process, predictions about task complexity cannot be as accurate as some applied linguists claim they should be.

SummaryObjectives: To design, manufacture and analyze custom implants with functional gradation in macrostructure for attachment of amputation prostheses.Methods: The external shape of the implant was designed by extracting geometrical data of canine cadavers from computed tomography (CT) scans to suit the bone cavity. Three generations of implant designs were developed and were optimized with the help of fit/fill and mechanical performance of implant-cadaver bone assembly using CT analysis and compression testing, respectively. A final optimized, custom Ti6Al4V alloy amputation implant, with approximately 25% porosity in the proximal region and approximaltely zero percent porosity in the distal region, was fabricated using Laser Engineered Net Shaping (LENS™) – a laser based additive manufacturing technology.Results: The proposed design changes in the second generation designs, in terms of refining thresholds, increased the average fill of the bone cavity from 58% to 83%. Addition of a flange between the stem and the head in the second generation designs resulted in more than a seven-fold increase in the compressive load carrying capacity of the assembly. Application of LENS™ in the fabrication of present custom fit Ti6Al4V alloy implants enabled incorporation of 20 to 30% porosity in the proximal region and one to two percent residual porosity in the distal portion of the implant.Clinical significance: Patient specific prostheses having direct connection to the skeletal structure can potentially aid in problems related to load transfer and proprioception in amputees. Furthermore, application of LENS™ in the fabrication of custom implants can be faster to incorporate site specific porosity and gradients for improving long-term stability.

Full textAbstract:
With the introduction of the local police system, it is divided into national police affairs and local police affairs, raising the need to revise the previously implemented national police performance evaluation system to suit the circumstances of each region. Accordingly, the municipal police committees stipulate the evaluation of autonomous police affairs as their jurisdiction, but there are still no specific guidelines for evaluating the performance of autonomous police. Therefore, this study aims to establish guidelines for the performance evaluation of autonomous police by the municipal police committees. Accordingly, three out of six performance indicators have significantly improved the current indicators, two quantitative performance indicators have been maintained, and new traffic indicators have been developed so that the municipal police committees can actually play a role in evaluating the performance of the autonomous police. In addition, it proposes a performance evaluation system to motivate evaluators to pay attention and passion by proposing various incentives such as special pledges for excellent performance, on-site inspections of overseas autonomous police, individual commendations, group commendations, and prize money. As a result, the qualitative performance indicators proposed in this study are expected to increase local residents' trust in local police by autonomously preparing plans for local police affairs, continuously executing them regardless of personnel changes or accidents, and raising appropriate policing performance.

Education, videogames, and intelligent systems are all relevant topics for researchers. Determining means of improving academic performance using a range of techniques and tools is an important challenge. However, while there are currently websites and multimedia resources that help students to improve their knowledge on specific topics, these lack in not having intelligent agents that can evaluate students and recommend materials to suit the difficulty that a user is having in a given subject. In this sense, this paper aims at developing an intelligent system that allows interactive teaching in basic education using videogames. In particular, high school students’ skills in basic mathematical operations with fractions were used for testing experimentally the approach. An intelligent system was developed using computational techniques such as fuzzy logic and case-based reasoning to evaluate user performance and recommend additional study material according to the specific challenges from the given educational game. The use of the games was supported by ICT (information and communication technologies) tools on a web platform. Such a developed platform was tested by 206 high school students, who played 5400 games in total. The students showed an improvement of around 14% in the topics covered. The results indicate that the implementation jointly of videogames and intelligent systems allows users to improve their performance in the given topics.

Full textAbstract:
Insertions and deletions (indels) in human genomes are associated with a wide range of phenotypes, including various clinical disorders. High-throughput, next generation sequencing (NGS) technologies enable the detection of short genetic variants, such as single nucleotide variants (SNVs) and indels. However, the variant calling accuracy for indels remains considerably lower than for SNVs. Here we present a comparative study of the performance of variant calling tools for indel calling, evaluated with a wide repertoire of NGS datasets. While there is no single optimal tool to suit all circumstances, our results demonstrate that the choice of variant calling tool greatly impacts the precision and recall of indel calling. Furthermore, to reliably detect indels, it is essential to choose NGS technologies that offer a long read length and high coverage coupled with specific variant calling tools.

Full textAbstract:
The collection and separation of solid waste represent crucial stages in recycling. However, waste collection currently relies on static trash bins that lack customization to suit specific locations. By integrating artificial intelligence into trash bins, we can enhance their functionality. This study proposes the implementation of a sorting machine as an intelligent alternative to traditional trash bins. This machine autonomously segregates waste without human intervention, utilizing deep learning techniques and an embedded edge device for real-time sorting. Deploying a convolutional neural network model on a Raspberry Pi, the machine achieves solid waste identification and segregation via image recognition. Performance evaluation conducted on both the Stanford dataset and a dataset we created showcases the machine's high accuracy in detection and classification. Moreover, the proposed machine stands out for its simplicity and cost-effectiveness in implementation.

Full textAbstract:
Background: Nutrition fuels optimal performance for athletes. With increased research developments, numerous diets available, and publicity from professional athletes, a review of dietary patterns impact on athletic performance is warranted. Results: The Mediterranean diet is a low inflammatory diet linked to improved power and muscle endurance and body composition. Ketogenic diets are restrictive of carbohydrates and proteins. Though both show no decrements in weight loss, ketogenic diets, which is a more restrictive form of low-carbohydrate diets, can be more difficult to follow. High-protein and protein-paced versions of low-carbohydrate diets have also shown to benefit athletic performance. Plant-based diets have many variations. Vegans are at risk of micronutrient deficiencies and decreased leucine content, and therefore, decreased muscle protein synthesis. However, the literature has not shown decreases in performance compared to omnivores. Intermittent fasting has many different versions, which may not suit those with comorbidities or specific needs as well as lead to decreases in sprint speed and worsening time to exhaustion. Conclusions: This paper critically evaluates the research on diets in relation to athletic performance and details some of the potential risks that should be monitored. No one diet is universally recommend for athletes; however, this article provides the information for athletes to analyze, in conjunction with medical professional counsel, their own diet and consider sustainable changes that can help achieve performance and body habitus goals.

SUMMARY Comprehensive knowledge regarding Saccharomyces cerevisiae has accumulated over time, and today S. cerevisiae serves as a widley used biotechnological production organism as well as a eukaryotic model system. The high transformation efficiency, in addition to the availability of the complete yeast genome sequence, has facilitated genetic manipulation of this microorganism, and new approaches are constantly being taken to metabolicially engineer this organism in order to suit specific needs. In this paper, strategies and concepts for metabolic engineering are discussed and several examples based upon selected studies involving S. cerevisiae are reviewed. The many different studies of metabolic engineering using this organism illustrate all the categories of this multidisciplinary field: extension of substrate range, improvements of producitivity and yield, elimination of byproduct formation, improvement of process performance, improvements of cellular properties, and extension of product range including heterologous protein production.

Full textAbstract:
It is commonly accepted that market participants use ESG (Environment, social and governance) scores as an indicator of a company’s sustainability performance in terms of finances and reputations. Pharmaceutical industry is highly social related and increasingly exposed to climate change risks. In this study, 251 pharmaceutical companies and three leading enterprises are chosen to make out how ESG scores affect pharmaceutical industry?s stock returns and other financial performance. Using data from Wind and Bloomberg, we do an empirical analysis combined with theoretical analysis. We establish a linear regression model, to make regression of stock returns of the overall industry and ESG scores. The E, S and G scores are also analyzed respectively. Through the regression results, we find that better ESG performance doesn?t increase stock returns, which might due to a lagged effect of ESG performance on financial indicators. Also, higher systematic risks would decrease stock returns. As for specific companies, there are difference between their result and the overall industry. Higher ESG scores do effect stock returns of big companies, for instance, AbbVie and Pfizer, of which the stock returns are positively correlated to ESG scores, while Merck?s fact is negative but better suit for the model.

Full textAbstract:
The selection of football players is a complex process involving talent evaluation based on various performance indicators, combining objective measures with subjective assessments by coaches and scouts. This research aims to improve the football player selection process using the K-Means clustering method based on the attributes of transfer price, performance, body specifications, position, and player ability. The dataset used consists of 17.947 players taken from the FIFA 19 edition of the soFIFA.com platform, which includes complete information such as transfer price, performance, body specifications, position, and player ability. The data was processed using principal component analysis (PCA) to reduce the dimensions, followed by the Elbow Method to determine the optimal number of clusters. The clustering results show the distribution of players based on their on-field roles, such as center back, goalkeeper, striker, and left wing back. The profiling of players from each cluster is identified based on position, body type, dominant foot usage, transfer price, and rating. This research provides useful insights for coaches and scouts in selecting players that suit specific roles in the team using better analysis. The findings also highlight the importance of player clustering for data-driven decision-making, which can optimize team composition and overall performance.

Full textAbstract:
Aspect Ratio significantly influences the aerodynamic performance of aircraft, dictating crucial factors such as lift and glide efficiency. This paper investigates the impact of varying Aspect Ratios on the Gliding Angle of paper airplanes, serving as analogs for larger aircraft. Different models of paper airplanes, each with unique Aspect Ratios, are constructed and tested under controlled conditions to measure their aerodynamic responses. The experiment employs video tracking and statistical analysis to precisely gauge the glide angles and correlate these with Aspect Ratios. Results indicate that an increase in Aspect Ratio generally leads to a decrease in the Gliding Angle, suggesting enhanced aerodynamic performance. However, this relationship exhibits complexity beyond a straightforward linear association, hinting at the nuanced interactions between wing geometry and airflow dynamics. Further, the study explores the Lift to Drag ratio, revealing its dependency on the glide dynamics shaped by Aspect Ratio variations. These findings contribute to a deeper understanding of flight mechanics, potentially guiding the design of more efficient gliders and other aircraft by optimizing Aspect Ratios to suit specific flight requirements.

The success of BRT systems in cities such as Curitiba (Brazil), Bogotá (Colombia), Jakarta (Indonesia), Guangzhou, Beijing, Kunming (China), and Seoul (South Korea) has inspired the widespread adoption of the BRT model. However, popularize BRT systems worldwide has not always yielded successful outcomes, as evidenced by the dismantling of BRT systems in New Delhi (India), Bangkok (Thailand), and Kuala Lumpur (Malaysia) due to operational inefficiencies. This highlights the necessity of customizing BRT systems to suit the unique conditions of each city. This paper presents an analysis of the urban context of Ho Chi Minh City, addressing factors such as population distribution, land use, travel behavior, and the current state of transport infrastructure, to propose a BRT model optimized for the city’s specific conditions. The proposed result is a small-capacity BRT system with dedicated lanes shared with regular buses and open stations serving each direction is the most appropriate solution for the city. These research findings can be applied in the design of future BRT routes in Ho Chi Minh City

Full textAbstract:
According to Patrice Pavis(1998, pp. 337-8), "The key to a site-specific performance is the search for a venue that is often unconventional but has a historical significance and characteristic atmosphere, such as: a freight yard, an abandoned factory, a city block, a courtyard or a suite", in which a classical or contemporary text is incorporated and where the new framework will give the performance with a special charm and unexpected energy." In 2019 I participated as a dancer in a site-specific performance project—— (in)visible Dancing on a street in the city of London, which took place in London's Woolwich Town Centre, in the form of performers bursting onto the high street, crossroads and squares in seemingly improvised, site-specific dance, culminating in a performance by the performers, live musicians. The performance ends with a massive finale featuring the performers, live musicians and passers-by who have learned the steps. The aim of the project was to bring together different sections of the community, from apprentices to local performers and ordinary people, reconnecting them with their shopping streets and each other. This essay may use (in)visible Dancing as an example to analyze the relationship between site-specific performance and society and the city, and also the potential engagement of theatre with geography in the context of the expansion of site-specific performance.

Full textAbstract:
Common Spaces is an interface for real-time media convergence and live performance combining media, applications and devices. A multimodal media ecosystem was designed to respond to the requirement of a specific performance — how to mix multiple applications into a single environment. This collaborative environment provides a flexible interface for performers to negotiate, share, and mix media, applications, and devices. Common Spaces is a framework based on interoperability and data flow, a network of virtual wires connecting applications that “talk” to each other sharing resources through technologies such as OSC or Syphon. With this approach, media designers have the freedom to choose a set of applications and devices that best suit their needs and are not restricted to a unique environment. We have implemented and performed with this ecosystem in live events, demonstrating its feasibility. In our paper we describe the project's concept and methodology. In the proposed performance we will use the Digital Archive of Portuguese Experimental Literature (www.po-ex.net) as a framework, appropriating its database assets, remixing its contents, as well as the techniques and methods they imply, stimulating the understanding of the archive as variable and adaptable. These digital re-readings and re-codings of experimental poems further highlight the importance of the materialities of experimental writing, integrating self-awareness in the modes of exchanges between literature, music, animation, performance, and technology.

Purpose Companies with multiple roles, as both a profit generator and public service provider, have specific characteristics that differentiate them from single-role companies. However, literature suggests that no performance measurement framework exists to fully suit the characteristics of such companies. This study aims to develop a novel performance-measuring framework to manage logistics performance in multiple-role companies. Design/methodology/approach The framework is developed by combining a literature review and a case study approach as applied to a company with multiple roles. The case study is conducted to identify the characteristics of multiple-role companies, the factors that potentially affect such companies’ logistics performance and criteria for a new framework. The literature review identifies the concepts, performance attributes and indicators from existing frameworks with the potential for incorporation and synthesis in the new framework. Findings This study identified several characteristics, performance drivers and criteria for a logistics performance-measuring framework for multiple-role companies. Additionally, this study successfully developed a new logistics performance-measuring framework that consists of eight performance management stages and an aggregated index to measure overall logistics performance. Practical implications The proposed logistics performance-measuring methodology provides useful guidance for stakeholders of multiple-role companies to plan, organize, execute and evaluate logistics performance. Originality/value This research fills a theoretical gap by explaining the characteristics of logistics systems in multiple-role companies, as well as the factors that may affect such companies’ logistics performance. Further, the proposed framework contributes to academia by integrating performance attributes from several available frameworks to manage objective conflicts, dynamism issues and the inconsistent performance evaluations that exist in companies with multiple roles.

Smart city technologies are becoming dominant. One of the important pillars of a smart city is education. All citizens are learners in the smart city. To fulfill goals of a smart city, supported technology should be boosted. As a result of incorporation with the growing Information and Communication Technologies (ICT) along with software and hardware, learning environments have undergone numerous changes. Students and strategies represent the center point while adopting the online learning environment. This paper highlights important issues to shape electronic education. It considers Moodle-LMS to figure out the triangular relationship between the engagement, behavior and performance (EBP) of Sultan Qaboos Uinversity (SQU) students in any course. Moodle collects students’ information and generates students’ profiles. Researchers could analyze students’ profiles to findout relationships between different attributes (i.e. EBP). This could guide instructors to know how engagement and behavior could be used as an indication to improve students’ overall performance. This paper aims to suggest a test model intended to guide instructors to prepare personalized materials that suit individual students needs and overcome their deficiency towards a better performance. Another objective is to integrate the proposed model within Moodle environment. This paper uses data of 14 students from a fully online course at SQU. This is used to explore whether patterns of student engagement and behavior are correlated with student performance. Findings reveal the existence of a positive relationship between EBP attributes. Authors recommend instructors to use students’ results to recognize students who need additional support in a specific course.

Full textAbstract:
A thermoelectric generator (TEG) cell is a solid-state semi-conductor capable of converting thermal energy directly into electrical energy. Studies on specific designs for TEG modules are needed for an effective industrial waste heat recovery. Typical TEG systems apply direct heating or cooling without being assisted by heat transfer devices which makes it difficult to maintain high temperature difference between TEG cells surfaces for higher electrical power generation. To suit the TEG system with the industrial condition, a waste heat recovery (WHR) module was developed consisting of a Bismuth Telluride TEG cell and another module consisting of two TEG cells in a stacked configuration. The TEG cells were sandwiched between two copper blocks and connected to two plate-finned heat sinks and eight heat pipes. The two modules were tested on a dedicated test bench to study its performance based on an industrial WHR setup. The hot stream waste heat temperature was constant at 80 ℃ while the cooling air streams were set based on ambient conditions between 22 ℃ to 30 °C. The maximum power performance (MPP) varied from 10 mW to 153 mW where the effect of cooling is very significant on the power outputs. Under forced cooling condition, the MPP generated from the double stacking TEG configuration is significantly higher compared to single cell configuration, by approximately 250%.

Full textAbstract:
The dynamical modeling and power optimization of floating wind–wave platforms, especially in regard to configurations based on constrained floating multi-body systems, lack in-depth systematic investigation. In this study, a floating wind-flap platform consisting of a flap-type wave energy converter and a floating offshore wind turbine is solved in the frequency domain considering the mechanical and hydrodynamic couplings of floating multi-body geometries and a model that suits the constraints of the hinge connection, which can accurately calculate the frequency domain dynamic response of the flap-type WEC. The results are compared with bottom-fixed flap-type wave energy converters in the absence of coupling with a floating wind platform. Moreover, combined with traditional optimization methods of power take-off systems for wave energy conversion, an optimization method is developed to suit the requirements of floating wind-flap platform configurations. The results are drawn for a specific operation site in the South China Sea, whereas a sensitivity analysis of the parameters is performed. It is found that the floating wind-flap platform has better wave energy absorption performance in the low-frequency range than the bottom-fixed flap-type wave energy converter; the average power generation in the low-frequency range can increase by up to 150 kW, mainly due to constructive hydrodynamic interactions, though it significantly fluctuates from the sea waves’ frequency range to the high-frequency range. Based on spectral analysis, operational results are drawn for irregular sea states, and the expected power for both types of flap-type WECs is around 30 kW, which points to a similar wave energy absorption performance when comparing the bottom-fixed flap with the flap within the hybrid configuration.

AbstractFatigue management in military aviation remains problematic and can be easily neglected by planners and aircrew in a busy operational environment. The basic assessment tool (BAT) is an objective and educational computer tool for evaluating and combining various fatigue factors. It provides an impartial performance comparison while at the same time educating and reminding its users of the importance of fatigue management. Individual factors of the BAT were chosen because they affect fatigue, sleepiness, alertness and performance. A short explanation of components not chosen is also included. An example of how the BAT can be used is described and figures of the resulting outputs (screenshots) are included. Most commercial fatigue estimation products are subjective and do not consider specific issues associated with tactical operations in a field environment. This novel approach can be used to help plan missions by minimizing the BAT score while still maximising the tactical advantage and keeping fatigue management fresh in the minds of military rotary wing pilots while in training and on operations. Although the BAT is military aviation focused and objective, it can be easily modified to suit particular fatigue concerns.

Many open motor skills, for example in team sports and combat sports, are executed under mild to severe conditions of instability. Therefore, over the past two decades, coaching professionals and athletes have shown increasing interest in training routines to enhance the physical prerequisites for strength performance in this regard. Exercise scientists have identified instability resistance training as a possible means to improve strength performance under conditions of instability with a special emphasis on the core muscles. In this letter article, more specifically, we firstly argue that effects of resistance training may be found not only in the core muscles but in the stabilizer muscles in general. Moreover, specific testing procedures are needed to assess strength performance under instability as compared to stable testing. As a second issue of this letter article, we consider instability to be an inappropriate term to characterize mild to moderate equilibrium disturbances during competition and exercise. Instead, when conceptualizing the human body as a dynamic system, metastability appears to better suit the conditions of strength performance on slippery surfaces, waves, during gusts of wind or tackling opponents for example. In fact, this term is conventionally used to characterize other dynamic systems in thermodynamics, financial markets, climatology, and social groups for instance. In the recent past, metastability has been discussed for issues in motor control as well. Hence, we argue that metastability idea should be applied to exercise science as well when assigning the biomechanical equilibrium conditions during perturbed strength performance.

The goal of the flocculation process is to change the particle size distribution to best suit the subsequent processes. Although several methods exist to evaluate the flocculation process, no single universally accepted method has yet to be developed. The purpose of this paper is to present experiences whereby particle counting was used in the diagnosis and optimization of the flocculation process. A commercially available on-line continuous particle counter has been used in evaluating the design and the operation of this process at two conventional Water Treatment Plants. The evaluation is based on particle dynamics, i.e., the change of the number of small and large particles. Some design deficiencies in the distribution channel and flocculation process have been identified from this method, and thus some operational parameters are suggested for optimum performance. Because the optimum condition may be site-specific, the method presented in this paper will be beneficial in the evaluation of the flocculation process at other water treatment plants.

Location information is the primary feature of wireless sensor networks, and it is more critical for Mobile Wireless Sensor Networks (MWSN) to monitor specific targets. How to improve the localization accuracy is a challenging problem for researchers. In this paper, the Gaussian probability distribution model is applied to randomize the individual during the migration of the Adaptive Fish Migration Optimization (AFMO) algorithm. The performance of the novel algorithm is verified by the CEC 2013 test suit, and the result is compared with other famous heuristic algorithms. Compared to other well-known heuristics, the new algorithm achieves the best results in almost 21 of all 28 test functions. In addition, the novel algorithm significantly reduces the localization error of MWSN, the simulation results show that the accuracy of the new algorithm is more than 5% higher than that of other heuristic algorithms in terms of mobile sensor node positioning, and more than 100% higher than that without the heuristic algorithm.

As the interest in Virtual Reality (VR) increases, so does the number of software toolkits available for various VR applications. Given that more games are being made with the Unity game engine than any other game technology, several of these toolkits are developed to be directly imported into Unity. A feature and interaction comparison of the toolkits is needed by Unity developers to properly suit one for a specific application. This paper presents an overview and comparison of several virtual reality toolkits available for developers using the Unity game engine. getReal3D, MiddleVR, and Reality-based User Interface System (RUIS) are analysed for VR interaction and display on multi-projection immersive environments like Cave Automatic Virtual Environments (CAVE)s. MiddleVR was found to have the highest performance and most versatile toolkit for CAVE display and interaction. However, taking cost into account, RUIS is the clear winner as it is available for free under the Lesser General Public License (LGPL) Version 3 license.

This paper investigates some of the currently available optical disk storage and retrieval systems, image manipulation systems and OCR systems. Future developments are presented and an attempt at outlining a longer term trend is made. The main conclusions of the paper are as follows: 1. Optical disk systems which are currently available are costly and are accompanied by excessive software and hardware capabilities which might be beyond the needs of the straightforward document storage and retrieval application. A tailor-made system to suit a specific application might be the route to follow provided read-only and multiple access operations are required and the optical system has a definite overall performance advantage over-microform. 2. In general, the document handling times of both the scanners and the printers of optical systems present a constraint on their continued rapid operation. 3. For general applications it might be advisable to wait for at least a year or two by which time erasable disk media should be available and some degree of disk standardization will have evolved. Costs however could still be a factor at that time. 4. The office-supplies industry is not expecting optical systems to have an appreciable effect on the ‘paperless office’ before 1990. 5. Image manipulation systems currently available are too generalized, slow and require excessive computer storage. Their range of performance is somewhat limited. Should such a system be required, it would be best to develop application-specific software taking advantage of computer configuration.
