M-ary quadrature amplitude modulation order optimization for terahertz wireless communications over dispersive channels
Authors: Karl Strecker  , Sabit Ekin  , John O'Hara
Published: October 2021

Highly accurate atmospheric models, based on molecular resonance information contained within the HITRAN database, were used to simulate the propagation of high capacity single-carrier quadrature amplitude modulated signals through the atmosphere for various modulation orders. For high-bandwidth signals such as those considered in this work, group velocity dispersion caused by atmospheric gases distorts the modulated waveform, which may produce bit errors. This leads to stricter Signal-To-Noise Ratio requirements for error-free operation, and this effect is more pronounced in high-order modulation schemes. At the same time, high-order modulation schemes are more spectrally efficient, which reduces the bandwidth required to maintain a given data rate, and thus reduces the total group velocity dispersion in the link, resulting in less distortion and better performance. Our work with M-ary quadrature amplitude modulated signals shows that optimal selection of modulation order can minimize these conflicting effects, resulting in decreased error rate, and reducing the performance requirements placed on any equalizers, other dispersion-compensating technologies, or signal processing hardware.

Published: October 2021

COVID-19 has made the immersive experiences such as video conferencing, virtual reality/augmented reality, the most important modes of exchanging information. Despite much advancement in the network bandwidth and codec techniques, the current system still suffers from glitches, lags and poor video quality, especially under unreliable network conditions. In this paper, we propose the method of a video streaming pipeline to provide better video quality under erratic network conditions. We propose an environment where the participants can interact with each other through video conferencing by only sending the audio in the network. We propose a Multimodal Adaptive Normalization (MAN)-based architecture to synthesize a talking person video of arbitrary length using as input: an audio signal and a single image of a person. The architecture uses multimodal adaptive normalization, keypoint heatmap predictor, optical flow predictor and class activation map-based layers to learn movements of expressive facial components and hence generates a highly expressive talking-head video of the given person. We demonstrate the effectiveness of proposed streaming that dynamically controls the Quality of Experience (QoE) as per the requirements.
Resource tokenization for crowdfunding of wireless networks
Authors: Volkan Sevindik
Published: October 2021

This paper presents a novel blockchain-based spectrum tokenization method used to crowdsource wireless network deployment projects. Crowdsourcing is a method of financing certain projects and ideas through the funds collected by individuals or businesses in an open marketplace. The method presented in this paper finances the wireless network deployment projects belonging to service providers or governments. The method tokenizes proposed novel wireless resource units, and sells these units to investors. A new Value Unit Per User (VUPU) resource unit is introduced with a new pricing scheme depending on a load of a base station. A novel Proof of Data Load (PoDLO) consensus algorithm is proposed which is used to verify data and traffic load of a base station. Device Diversity Factor (DDF) and Subscriber Unique Permanent Identifier (SUPI) Factor (SUF) are proposed new ways to determine the value of a base station and a network cluster.
Federated learning for IoE environments: A service provider revenue maximization framework
Authors: Benedetta Picano  , Romano Fantacci  , Tommaso Pecorella  , Adnan Rashid
Published: October 2021

In accordance with the Internet of Everything (IoE) paradigm, millions of people and billions of devices are expected to be connected to each other, giving rise to an ever increasing demand for application services with a strict quality of service requirements. Therefore, service providers are dealing with the functional integration of the classical cloud computing architecture with edge computing networks. However, the intrinsic limited capacity of the edge computing nodes implies the need for proper virtual functions' allocations to improve user satisfaction and service fulfillment. In this sense, demand prediction is crucial in services management and exploitation. The main challenge here consists of the high variability of application requests that result in inaccurate forecasts. Federated learning has recently emerged as a solution to train mathematical learning models on the users' site. This paper investigates the application of federated learning to virtual functions demand prediction in IoE based edge cloud computing systems, to preserve the data security and maximise service provider revenue. Additionally, the paper proposes a virtual function placement based on the services demand prediction provided by the federated learning module. A matching based tasks allocation is proposed. Finally, numerical results validate the proposed approach, compared with a chaos theory prediction scheme.

Authors: Xiao-Xia Zhang Xiao-Xia Zhang , Xiao-Xia Zhang Yin-Yin Hu , Yin-Yin Hu Jiao Yang
Published: October 2021

Prediction of milling force plays an important role in milling process of titanium alloy. In this paper, the milling process of titanium alloy is studied, and the material quality is affected directly by the milling force. Support vector regression (SVR) has shown a prominent performance for many practical applications. Although there is some literature about parameter optimization techniques of SVR model, it still needs further research and improvement on the performance and accuracy of this model. We present a hybrid milling force prediction model, namely DE&SVR, which hybridizes the SVR with differential evolution (DE) to enhance the prediction accuracy for milling force of titanium alloy. The main advantage of hybrid model is that the DE is adopted to optimize the kernel parameters of the SVR. The main parameters affecting milling force, such as the milling depth, feeding speed, and cutting speed, are considered in this study. The results have shown that the hybrid model yields better prediction accuracy, and the percentage prediction milling force deviation is found to be less than 3.5% for all the cases tested, NRMSE is only 0.0200, and MAPE is only 1.4791%. Thus, this methodology can be widely applied to the fields of material processing optimization.

Published: October 2021

Deep neural networks (DNNs) have been applied in various machine learning tasks with the success of deep learning technologies. However, they are surprisingly vulnerable to adversarial examples, which can easily fool deep neural networks. Due to this drawback of deep neural networks, numerous methods have been proposed to eliminate the effect of adversarial examples. Although they do play a significant role in protecting deep neural networks, most of them all have one flaw in common. They are only effective for certain types of adversarial examples. This paper proposes an ensemble denoiser based on generative adversarial networks (GANs) to protect deep neural networks. This proposed method aims to remove the effect of multiple types of adversarial examples before they are fed into deep neural networks. Therefore, it is model-independent and cannot modify deep neural networks’ parameters. We employ a generative adversarial network for this proposed method to learn multiple mappings between adversarial examples and benign examples. Each mapping behaves differently for different types of adversarial examples. Therefore, we integrate these mappings as the ultimate method to defend against multiple types of adversarial examples. Experiments are conducted on the MNIST and CIFAR10 datasets. We compare this proposed method with several existing excellent methods. Results show that this proposed method achieves better performance than other methods when defending against multiple types of adversarial examples.

Cloud service systems bring together a wide variety of flexible and scalable mass services. The service combination scheme which can meet the user’s needs is provided to the user through the flexible and changing service mode of service combination technology. However, service combination failures often occur. In view of the above problems, this paper establishes the cloud service combination optimization model. Firstly, it is proposed that the Service Combination Optimization Petri Net models and analyzes the service selection and combination. In order to avoid local convergence, combining Service Combination Optimization Petri Net with improved Genetic Algorithm, a service combination model based on Local Search Operator Genetic Algorithm is proposed, and the legitimacy of service combination sequence is verified by Petri net. The results of experiment show that the Petri net service composition model can effectively verify the constraints of service composition and the logical rationality of the system, the Local Search Operator Genetic Algorithm effectively reduces the search space and improves the convergence rate. Compared with other algorithms, the execution efficiency and accuracy of Local Search Operator Genetic Algorithm are improved.

Covid-19 has been threatening human life and is now the most serious public health issue in the world. During this pandemic, wearing masks is one of the most effective ways to inhibit virus transmission. However, existing ubiquitous identity recognition requires people to remove their masks to complete facial recognition, which is highly risky. Iris recognition, as a safer applicable identification method, has its fatal weakness of not being able to achieve satisfactory real-time recognition on end devices. This paper presents an edge deployment of a low-power iris recognition system based on FPGA with approximate multipliers. We adopted a serial-parallel hybrid method for the preprocessing stage, trained the CNN model on PC and then deployed the architecture and parameters on FPGA. We further reduced power and resource consumption by designing approximate multipliers for the key calculation. Experimental results show that design achieves up 28% and 43% gain in terms of area and latency energy product, while incurring a negligible accuracy loss. The recognition speed increased by 40% compared with Raspberry Pi, 11 times better than Jetson Nano power latency production.

Published: October 2021

With the rise of the Internet of Things, edge computing has become one of the key technologies in Internet of Things solutions. In the context of the Industrial Internet of Things, hierarchical edge computing shows its advantages. This article focuses on hierarchical edge computing in the industrial Internet of Things scene, and studies the dynamic resource allocation of hierarchical edge computing networks. When using a hierarchical edge computing network with existing equipment, it is difficult to make changes to existing equipment. Therefore, this article uses queuing theory modeling analysis and proposes Dynamic Link Model based on Nodes Relation. Aiming at the hierarchical edge computing network, this model uses a method based on node connection relationship transfer to achieve load balancing of task flow and completes the dynamic allocation of computing resources in the network, and proposes a time experienced priority queue offloading strategy. The paper uses Java to achieve a dynamic link model experiment based on the connection relationship between nodes. The results show that this scheme has significant advantages in the global average delay of the system, and ensure the loss probability is reasonable within a certain limit.

This article focuses on hierarchical edge computing in the industrial Internet of Things scenario, and studies the static resource deployment of hierarchical edge computing networks. When deploying a hierarchical edge computing network with new equipment, the allocation of computing capacity between layers is one of the hot is-sues. This paper proposes a method for the allocation of edge computing node capacity between layers based on the M/M/1/c queue model, delay and call loss are performance indicators, and the optimal inter-layer capacity allocation algorithm is designed and implemented. This algorithm can reduce the global average delay of the sys-tem under the premise of meeting the requirement of call loss rate. Simulation verification shows that the optimal inter-layer capacity allocation algorithm can effectively reduce the system’s global average delay and call loss rate under the condition of a certain total system cost.

Published: October 2021

In recent years, with the continuous maturity of blockchain technology, more and more applications based on blockchain appear in our life. The safe sharing and rapid disposal of caseinvolved property information is the focus of online case management. At present, due to some characteristics of case-involved properties, the case platform with centralized management has some issues, such as low collaborative efficiency and low intelligence. In this paper, we propose the architecture and implementation scheme of the cross departmental case-involved property transfer system based on blockchain. By introducing the blockchain technology, we have established a multi departmental case-involved property information transfer alliance chain across the public security, procuratorial and judicial departments. The case-involved property transfer system uses smart contract to implement a set of case-involved property transfer procedures designed by our investigation and research. It proposes an infrastructure of alliance blockchain based on multi-chain technology according to the business logic and makes the public security, procuratorial and judicial departments as the alliance blockchain nodes. Blockchain technology can make all nodes store transaction data. So it can efficiently realize the sharing of case-involved property information, leave traces in transaction processing and trace the processing source of case-involved properties.

Authors: Mittal Neelam , Singhal Surabhi
Published: October 2021

Gender Inclusion at the workplace is a necessary step towards eclectic growth of an organisation, holistic development of society at large and sustainable development at the national and global level. The trajectory towards gender equality and the simultaneous abrogation of gender gap at the macro-level begins with bringing about changes at the micro-level. This article aims to explore the extant condition of the working women, what they feel about the security of women at the workplace, both at present and in the futuristic hybrid model and the possible changes which can make the workplace amenable to their safety and further ameliorate the workplace environment.  An effort has also been made to skim through the existing women-centred policies like the Prevention, Prohibition and Redressal of Sexual Harassment at the workplace (POSH) Act, 2013; women’s awareness of the existence of such laws and the implementation of the same in praxis. Responses of working women in the corporate sector have been analysed and their expectations about enhancing safety at the workplace have been used for recommending further policy decisions.

Authors: Dhusia Devendra Kumar , Gupta Pankaj Kumar , Mital Neena , Jain Renu
Published: October 2021

With the technological advancement and changes in the working and lifestyles of people and industry, the rate of obsolesce of electrical and electronic equipment and gadgets, particularly computers and mobile phones, is high, posing a threat to health and environment creating a threat to sustainability for nations around the globe. Realizing the difficulties of e-waste management, many developed countries have started dumping the e-waste to developing nations that suffer from resources constraints, thus leading to hazardous activities mainly in the informal sector. Therefore, we are motivated to examine whether the awareness of the environment, attitudes, and beliefs, particularly knowledge (constructs), impact practices relating to management of e-waste in India. Analysis of the results of our survey of 180 respondents through SEM model show an insignificant association of these constructs with e-waste management practices. However, we find a significant mediating role of Environmental Knowledge in all these relationships.

Published: October 2021

Artificial Intelligence is one of the emerging technologies with the most potential nowadays. The scale of use is increasingly broad, and many compa-nies are involved in developing this technolog y with significant investments. In this sense, intellectual property issues have been raised in several legal systems, with different approaches. Knowing who owns the copyright of works produced by an AI is crucial as it will directly impact the development of this technolog y. Furthermore, it is paramount for fully autonomous AI, as there is no human intervention in these. Another path would be creating a robotic legal personality, which raises ethical and legal issues that will take time to overcome.

A FUNÇÃO DA EPÍGRAFE EM DA COSTA E SILVA (1885-1950) : O MAIOR POETA CANÔNICO DO PIAUÍ
Authors: Francisco da Cunha e Silva Filho
Published: October 2021

Este ensaio discute o emprego de cinco epígrafes referentes, respectivamente, ao poema “Verharen” (citado em duas epígrafes), a Rubén Darío, a Shakespeare e a um brevíssimo fragmento de uma carta amorosa na produção poética de Da Costa e Silva. O poeta nasceu em Amarante, estado do Piauí. Sua poesia vai do Parnasianismo, Simbolismo a formas próximas do Modernismo. Ademais, poder-se-ia arriscar afirmando que, por ser um poeta tão versátil e multifacetado, alguns de seus poemas nos vislumbram tons românticos em razão da presença de um lirismo contido, sobretudo em temas amoroso-afetivos. Em sua fase mais avançada revelava claros traços de um poeta inclinado a formas mais modernas de versos, i.e., alguns de seus últimos poemas demonstravam que ele, tal como fez Manuel Bandeira, terminaria aderindo à moderna dicção poética, caso não fosse tragado pela morte relativamente cedo. Em uns poucos poemas da sua fase mais recente, pelo avanço que ia imprimindo à sua dicção, poder-se-ia defini-locomo um dos precursores do Concretismo de 1956, um movimento de vanguarda da poesia brasileira iniciado em São Paulo.

Published: October 2021

Over the last decade, there has been a significant increase in the development of mobile applications. The performance of the developed applications depends largely on the development approaches. There are two widely used approaches: (1) native, where the application is targeted and developed for a specific platform, (2) crossplatform, where the developed application runs on multiple platforms. This paper aims to address the question of which approach should be used in various scenarios. We have performed a detailed comparison of the two approaches by developing a mobile app using both approaches. Experiments are performed using Android and iOS, the two most well-known mobile Operating System. The criteria of deciding the best approach include performance, usability and support. Our results show that both approaches are viable depending on the requirements and type of the application to be developed, with native having an edge. Guidelines are presented at the end to help the developers in choosing the best approach. The fundamental differences and advantages of each approach are discussed.

Authors: Златкова-Дончева Катерина
Published: October 2021

Представеното изследване проследява поведенческите проявления на тревожност и агресивност при деца с емоционално-поведенчески нарушения, като се анализира индивидуален случай. Изследваното дете е един от участниците в проведен експеримент с 40 деца, отглеждани извън семейна среда, който проследява влиянието на езика върху нивата им на агресивност и тревожност посредством 4 стратегии за взаимодействие: нормален тон на гласа и позитивен език, повишен тон на гласа и позитивен език, нормален тон на гласа и негативен език и повишен тон на гласа и негативен език. Резултатите извеждат тенденцията за силната зависимост между тревожност и агресивни прояви, както и за неефективността при използването на негативен език с повишен тон при деца с емоционално-поведенчески проблеми. Същевременно казусът разкрива допълнителни нюанси по отношение на училищната успеваемост, която се намира в зависимост от социално-комуникативното развитие и емоционално-поведенческото състояние на детето.

Authors: Ponomarenko Tatyana , Badjanova Jeļena
Published: October 2021

Moral education of preschool children is a focused process of their initiation of moral values of mankind (humanism, kindness, humanity, justice, mercy and altruism) and stimulation of manifestations of empathy, sympathy and support in people’ world. Moral education is of great importance in the modern, very dynamic and constantly changing world. There is an urgent necessity to understand that human community is a family, where everyone is a part of the universal whole. It is necessary to avoid conflicts and wars in unity and live in peace. To overcome disputes and solve common problems at the negotiating table rather than by means of armed conflicts. To provide political, economic and social development of society constructively. To overcome any obstacles for free, democratic communication and human interaction. Moral education of preschoolers is based on specially developed content presented in educational programmes. The development and improvement of programmes is carried out throughout the entire period of development of national preschool education. Every document of the programme is created at a certain historical stage of development of society, reflecting its political, economic and social status as well as the level of development of the theory and practice of preschool education. At the present stage of the development of national preschool education, there is a need to study the history of development of the content of moral education of preschool children in national and foreign (Russian) educational programmes, which has not been studied specifically before. This has become the goal of our study and helped to set the objectives and content of moral education of preschoolers for the new edition of the program “Child” (2016)

The topic of aggression is extremely relevant in our daily lives and this is why it is often the subject of theoretical and practical analysis. In the context of institutional care, it acquires specific dimensions related to a number of factors. This article presents two cases of residents of residential institutions for children and young people with disabilities, with an emphasis on influencing their level of aggressive response to reality. At the root of the interaction proposed are the ideas for supporting communication and for verbalizing desires and experiences in the context of group work. The cases described testify to the existence of positive tendencies in the ability to regulate one’s own behaviour in the natural environment as well as in situations of provocation by others.

Идентичност, себеутвърждаване и себерефлексия при ученици и студенти
Authors: Vasilev Boyan
Published: October 2021

Уменията за себерефлексия се изграждат като част от общото психосоциално развитие и себеопределяне и процесът може да бъде целенасочено подкрепен. Умението за поддържане на оптимална себеоценка и себеусещане се формира в хода на търсене и откриване на себе си във връзка с възможностите и стремежа към себеутвърждаване. Представени са резултатите, получени от изследвани 364 ученици и студенти като представители на най-сензитивния период на изграждане на идентичността. Акцентът е основно върху взаимните връзки между себеутвърждаването и идентичността. Данните от емпиричното изследване върху феномените себеутвърждаване и идентичност са интерпретирани от гледна точка на личностната рефлексия. Те разкриват, че повишеният стремеж към себеутвърждаване – независимо дали чрез ориентация към другите и търсене на външна подкрепа, или реализиран чрез собствени успехи и автономно, води до по-успешно себеопределяне и стимулира изграждането на психосоциална идентичност. Изведените връзки имат приложимост в учебна среда и могат да бъдат полезни за всички, ангажирани в обучението и работата с ученици и студенти.
Теоретични основи на опитно-изследователска дейност по човекът и природа в началните класове
Authors: Иванова Цветомира
Published: October 2021

В статията се представя структурата на опитно-изследователска дейност в съпоставка със структурата на дейността и в частност –със структурата на познавателната дейност. Направена е интерпретация на структурните ѝ компоненти и присъщите им изследователски умения от гледна точка на пълноценното усвояване на учебното съдържание по човекът и природата в началните класове. „Целта“ е откроена като ключов компонент от тази структура, тъй като от степента на нейното осъзнаване и формулирането ѝ в голяма степен зависи успехът на дейността (в частност и този на опитно-изследователската дейност). Стремежът към прерастване на мотивационната система от отделни поведенчески актове (при провеждането на отделни експерименти) в система от мотиви на цялостно поведение на личността (зараждане на изследователски дух и трайна познавателна потребност да се изследва, проучва, проверява, доказва) е откроен за ключов момент в опитно-изследователската дейност на учениците. Поставя се акцент върху значимостта на прехода през всичките ѝ компоненти, за да бъде тя пълноценна, за да се достигне до резултат, практическата приложимост на който е необходимо да се покаже.

Centralisation and Decentralisation in Higher Education: a Comparative Study of Hungary and Germany
Authors: Rodrigues Pimenta Carla , Rónay Zoltan , Német András
Published: October 2021

The main focus of this article is on comparing the centralisation and decentralisation in higher education in Hungary and Germany. This study explores trends in implementing quality assurance measures in higher education. It employs the methodology of document analysis to identify differences between the two nations in the level of autonomy they accord to higher education institutions in regulating quality assurance standards. Data collected from these documents demonstrate that the two countries have divergent approaches to higher education governance. In the Hungarian higher education system, management is centralised and monitored by the national government. This state control indicates limited autonomy amongst higher education institutions to organise academic programs. In contrast, the German legal documents examined in this study indicate a belief in the need to guarantee the quality of learning, teaching, research, academic freedom, gender equality, and institutional autonomy. The data collected reveal the close relationship between governance and quality assurance in discourses regarding the accountability, transparency, and freedom of stakeholders.
“Olho por olho, dente por dente” o erro e o castigo na bíblia e na ciência do direito
Authors: Oliveira Rodrigo Rios Faria de , Vitório Jaldemir
Published: October 2021

O estudo abordará as questões normativas legais contidas na Torah, e suas retomadas e reformulações na ciência do direito, ocupando-se das linguagens jurídica e teológica, muitas vezes ininteligível, devido ao formalismo, que provoca o “efeito de desconhecimento” sobre o texto religioso, mais propriamente na questão do “olho por olho, dente por dente”. Verificará, assim, as questões acerca do erro e do consequente castigo e ou punição contidas na Bíblia, em Deuteronômio, e as possíveis relações para com a ciência do Direito. Dessa forma, procurará observar concepção de lei presente na Torah, a fim de explicitar as iluminações que a tradição bíblica pode oferecer para o direito moderno e, dessa forma, postular uma prática do direito mais humanizadora.

Background: Androgen deficiency in aging male (ADAM) is characterized by hypogonadism with symptoms such as reduced sexual desire, muscle mass loss, among others. The treatment with testosterone gel and the results around weight and other indicators are the research objects. Objective: Analysis of association between ADAM and obesity in the outpatient population studied and to verify the outcomes of the testosterone gel treatment. Materials & Methods: From a group of 126 outpatients of University Hospital Mário Palmério, 40 were selected with total testosterone lower than 300ng/dL, upon the signature of written informed consent form and the realization of laboratory tests. After new testosterone dosage and urologic evaluation, 6 patients were treated for an average time of 6 months. Initially the dosage was 50 mg/day, with medical consultations and laboratory tests to verify the effects and to adjust the dosage. The variables analyzed were BMI, abdominal circumference, weight, muscle mass, body and visceral fat, in addition to testosterone serum dosages, lipid profile, amongst others, considering the test t among the beginning and end of treatment, defining the significance level by p<0,05. Results: Significant increase of total testosterone levels (p<0,001) and a tendency of improvement in the free testosterone levels (p=0,061) and no significant reduction of BMI (p=0,4308), abdominal circumference (p=0,1695), weight (p=0,999), body fat (p=0,194) and muscle mass (p=0,632), while visceral fat increased (p=0,5265). Vitamin D had no significant increase (p=0,2422). Conclusion: The total testosterone level was increased after the testosterone gel treatment with statistical significance, however there must be new research with more subjects with ADAM to prove the benefits of this treatment.
