Research on 3D Human Motion Capture Algorithm for Online Physical Education Teaching

This study proposes to use the gradient descent method in data fusion to solve the problem of low learning efficiency of online sports courses by optimizing the attitude calculation and combining gait detection and zero speed correction to form a three-dimensional human motion capture system. The system was applied to online physical education teaching to improve teaching quality. The performance of the optimized attitude calculation algorithm and the Kalman filter algorithm was compared. The results show that the error angle of the data-fusion-attitude calculation algorithm was 1.67°, which is better than the Kalman filter algorithm. In the empirical analysis of the 3D human motion capture system designed by the research, the system could correctly capture the real human motion trajectory. Moreover, comparative analysis of the online physical education courses showed that the satisfaction of the online physical education courses embedded in the system was 90.62, which was much higher than other online physical education courses. These results show that the optimized attitude calculation algorithm can better capture real human movements, and the human motion capture system composed of this can improve the learning effect of online physical education courses. This method opens up new ideas for online physical education teaching.

The Effects of Countermeasures on the Statements of Truth-tellers and Liars

거짓을 탐지하기 위한 폭넓은 연구를 통해 다양한 거짓 탐지 기법이 고안되었다. 하지만 거짓 탐지 기법이 새로 소개될 때마다 이러한 기법에 저항하는 대응기법의 등장에 대한 우려도 늘 함께해왔다. 이에 본 연구에서는 실증적인 연구가 충분히 이루어지지 않은 언어적 거짓 탐지에 저항하는 대응기법의 효과를 살펴보았다. 특히 법률 전문가 등에 의해 실무적으로 제공되는 대응기법과 학문적인 연구 결과를 바탕으로 하는 대응기법을 구분하여 각 대응기법이 진실과 거짓 화자의 진술 내용에 미치는 영향을 살펴보았다. 그 결과 학문적 근거에 기반한 대응기법은 진술의 양을 증가시켜 더욱 진실하게 보이도록 만들었다. 하지만, 실무적인 대응기법은 오히려 대응기법을 활용하지 않은 진술보다 진술의 구체성과 풍부함을 저하시키는 것으로 나타났다. 이는 표면적인 진술의 특성에 의존하는 것은 거짓 탐지의 정확성을 보장해주지 못하므로 진술의 질적인 측면을 고려하여야 함을 시사한다. 추후 다양한 대응기법의 효과에 대한 연구의 필요성을 논의하였다. Various techniques to detect lie have been devised through extensive research. Along with this introductions, there have been concerns about emergence of countermeasures that resist lie detection. Therefore, this study aimed to empirically test the effects of countermeasures on verbal lie detection, which has not been sufficiently researched. In particular, the effetss of countermeasures on truth-tellers and liars were examined by dividing the countermeasures into practice-based and research-based. As a result, the research-based countermeasures made the statement seem more sincere. However, it was found that the practice-based countermeasures rather reduced the number of details in the statement than the statement without countermeasure. This can be evaluated as having low validity depending on the statement assessment tool, so the effectiveness of countermeasures should be sufficiently verified thruough follow-up studies. In addition, it suggests that the effectiveness of countermeasures needs to be counsidered in the current statement credibility assessment process, which focuses on the abundance of statements.
Productive Asset Management Methodology Technique in Virtual Machines to Increase CPU Utilization

One of the technologies with the quickest growth is cloud computing, which is utilized in many applications where customers can access virtual machines (VMs) that are offered by cloud service providers in data centers. The ideal distribution should meet both the needs of users and service providers. A2OA, an adaptive Archimedes optimization algorithm, is the suggested mechanism for allocating resources in cloud computing. The optimization problem will be solved and user tasks will be distributed using this adaptive approach. The adaptive approach will combine the Seagull Optimization Algorithm with the Archimedes Optimization Algorithm (AOA) (SOA). The update procedure in the AOA will be improved. in cooperation with the SOA. The tasks will be distributed to the user optimally based on the proposed A2OA. In MATLAB, the suggested methodology will be put into practice, and results will be examined. Performance metrics such make span, load standard deviation, load ratio, user provider satisfaction level, response time, and convergence analysis will be used to assess how well the suggested methodology performs. The suggested approach will be contrasted with the traditional approaches, including the Genetic Algorithm (GA), Particle Swarm Algorithm (PSO), and Whale Optimization Algorithm (WOA), respectively. Key Word: Virtual machines, adaptive Archimedes optimization algorithm (A2OA), Seagull Optimization Algorithm (SOA), Genetic Algorithm (GA), maximum power, load ratio
Evaluation of Red Cell Distribution Width (RDW) in Anemic Goats

Background: Red cell distribution width (RDW) measures the degree of anisocytosis in an erythrocyte population and was expressed as the coefficient of variation of the erythrocyte size distribution data. In recent studies, RDW has been evolved as a new predictive marker and as an independent risk factor in assessing the severity and progression of disease conditions. The data regarding RDW in goats was found lacking particularly in conditions like anemia. Methods: The study was conducted at Veterinary Clinical Complex, VCRI Orathanadu. The EDTA blood samples from suspected cases were collected and analyzed by Veterinary specific automated hematology analyzer. During the study goats with hemoglobin values lesser than and or equal to 8.0 g/dl were selected to evaluate the RDW alterations in them. Result: The Red cell distribution width was found elevated (36.94±0.29%) in anemic goats when compared to the healthy reference. The data of the Red cell distribution width in goats was recorded and statistically analysed.
On the Relation Between the Hard Problem of Consciousness and the Combination Problem for Panpsychism

The paper compares two problems in the analytical philosophy of mind: the hard problem of consciousness and the combination problem for panpsychism. The former arises for a wide range of materialist approaches, including physicalism. Panpsychism is asserted by its proponents as the best solution to the combination problem. However, panpsychism itself is faced with the combination problem. A comparison of these problems demonstrates that constitutive panpsychism is fundamentally incapable of solving the hard problem of consciousness. This is demonstrated by the structural and substantive similarity of the arguments in favour of each problem. The author shows that constitutive panpsychism is an extension of physicalism specifically designed to solve the hard problem. Further, the arguments from conceivability in favour of the hard and combination problems are compared, demonstrating their structural similarity. In addition, the author points out the substantive similarity of these problems by comparing individual types of argumentations. This allows us to accept the hypothesis that one of the reasons for the problems of panpsychism and physicalism may lie in mereological atomism, which unites these approaches. Thus, the association of the hard and combination problems can serve as an argument against mereological atomism in both panpsychism and physicalism. Based on the analysis of both problems, general conclusions are drawn about the prospects for the approaches in question and a direction of research is proposed in which the general problems of constitutive panpsychism and physicalism could be solved. It is shown that there is at least one acceptable naturalistic alternative to atomism: priority monism, which can be a strategy for solving the considered problems for both physicalism and panpsychism.
Modulation signal identification and classification based on the OA algorithm model

Most of the research on identifying and classifying signal models is limited to single signals such as AM, QAM or PSK, and there is a lack of research on the parameters of the identified signals. To make up for this deficiency, an OA (Optimality Confidence and Amplitude Ratio factor) algorithm model is proposed to identify and classify 13 kinds of modulation signals, including 2 kinds of analogue modulation signals (AM and FM), 11 kinds of signal digital modulation (M-SK and M-QAM). Based on the characteristics of the constellation diagram, Confidence and Amplitude Ratio factors are constructed to identify and classify signals with different parameters such as ’Format“, ”Centre Frequency“ and ”Sample Rate’ and different modulation types. In addition, because of the mis-judgement and confusion problems in identifying classification signals, a three-layer optimisation algorithm is proposed to optimise the OA algorithm model. Numerical simulation results show that the comprehensive identification efficiency of the proposed optimisation algorithm is increased by 18.84%.

Embracing the digital workplace: a SMART work design approach to supporting virtual work

Millions of workers have made the shift to working remotely during the outbreak of Covid-19, irrespective of their tasks, preferences, and abilities. The unprecedented large-scale experiment has challenged our understandings. Well-documented benefits of virtual work have been questioned, while various challenges have emerged and/or become more pronounced. Therefore, practitioners and scholars need to embrace the digital way of working in the coronavirus-forged world by considering how to support virtual work and improve working experiences. The current chapter frames virtual work as a system comprised of social and technical subsystems. To optimize the benefits of virtual work and minimize its potential risks, this chapter introduces a SMART work design approach involving both altering the social subsystem and the technical subsystem. That is, high-quality virtual work is Stimulating, promotes Mastery, supports human Agency, encourages Relational features, and has Tolerable demands (i.e., SMART work).
Bringing technological affordances into virtual work

Scholars have been studying virtual work for over two decades, but the Covid-19 pandemic has brought renewed focus and meaning to the phenomenon of virtual work, as electronic interactions became normalized over face-to-face interactions for safety reasons. This chapter reviews prior research on the role and impacts of technology in virtual work. It then reviews the technological affordances perspective and argues for the need to incorporate it into the virtual work scholarship. Its benefits lie in helping to better theorize the role of technology in virtual work, bridging and integrating the virtual work scholarship, and keeping pace with the ever-changing technological landscape. The chapter ends by highlighting contemporary trends facing virtual workers and proposing future research directions to further propel the scholarship on virtual work forward.
A provably secure authenticated key exchange protocol based on lattice with stronger anonymity

Stronger anonymity password authentication key exchange protocols based on traditional cryptography are not resistant to quantum computing attacks, and there is no lattice-only anonymous password authentication key exchange protocol protocol that satisfies the strong anonymity requirement. Therefore, this paper constructs stronger anonymity PAKE protocol based on the ring learning with errors (RLWE) and smooth projective hash function (SPHF) based on ideal lattice. The proposed protocol can achieve stronger anonymity and resists to desynchronization attacks and quantum attack. The security of the protocol is proved under the BPR model. The security and performance analysis shows that the proposed PAKE protocol has better advantages in security and efficiency.

They spoke at Stetson University's annual National Conference on Law and Higher Education.
Cloud service quality assessment based on entropy weight method

Cloud computing is an emerging service computing model centered on web services and applications, which is used to manage, schedule, and integrate various resources distributed on the network. The rapid development of cloud computing has led to the emergence of a wide variety of cloud services. In the face of many cloud services, users generally select high-quality cloud services through user evaluations. However, the subjectivity of users' evaluation of services and false user evaluations make later users fail to select efficient services. To address this problem, the authors take the QoS (quality of service) of cloud services as the data base, obtain the subjective weights of cloud services by AHP hierarchical analysis, obtain the objective weights of cloud services by entropy weighting method, and obtain the recommendation degree of each service by weighting, and obtain the trustworthiness of cloud services by TOPSIS decision method at the same time, and finally propose to construct a cloud service trustworthiness metric model. This model reduces the influence of subjectivity of user evaluation on the trustworthiness assessment of cloud services by providing an objective and effective trustworthiness measure for cloud services. In this paper, the research focuses on processing QoS data, classifying the metrics, and using the entropy weight method to obtain the objective weights of the corresponding metrics of cloud services.

Research on quantum cheque based on the resolution of quantum state computing

In the quantum cheque schemes that have been proposed, a strong quantum capability of the user is required and the quantum resources consumption is relatively high. To solve this problem, we propose a quan tum cheque protocol based on quantum state computational distinguishability, in which a bank issues a blank cheque, a semi-classical user can sign the amount on the cheque and finally the bank verifies the validity of the cheque. Compared to existing scheme, our scheme requires less quantum capability and reduces the overhead of quantum resource. Since the scheme is based on a hard problem that can resist quantum attacks, the quantum cheque cannot be forged or altered.
Intellectual property transaction sharing scheme based on blockchain and proxy re-encryption

In view of the current problems of long property rights validation period, transaction difficulties and data sharing, we propose a blockchain-based Intellectual property transaction sharing scheme by combining the characteristics of open and transparent, tamper-evident, traceable and decentralized data of blockchain with the proxy re-encryption technology and off-chain storage mode. We also improve the PBFT master selection strategy and design the VCS-PBFT consensus mechanism, which effectively reduces the network bandwidth consumption and improves the consensus efficiency. By comparing and analyzing with other schemes, it shows that this scheme has certain advantages and feasibility in function.
