Phase synchronization of Wien bridge oscillator-based Josephson junction connected by hybrid synapse
Authors: Talonang Cédric Noufozo , Kammogne Alain Soup Tewa , Vaidyanathan Sundarapandian , Fotsin Hilaire Bertrand
Published: August 2022

In this paper, a nonlinear Josephson junction (JJ) based-Wien bridge circuit is analyzed and coupled in order to obtain synchronization through passive components. The electrical equations governing the operation of our circuit are obtained using the laws of electrical circuit analysis. Chaotic phenomenon is demonstrated in the proposed circuit using relevant indicators such as the phase portraits, bifurcation and the corresponding Lyapunov diagram. Several coupling topologies are considered to achieve the phase synchronization that provides a better understanding of the distribution of energy in the overall system. Additionally, the effect of the noise is considered which considerably brings an added value to the dynamic of the phase synchronization between oscillators. Full synchronization is observed when the resistor is connected in parallel with the inductor or capacitor while different results are obtained when the resistor is connected in series with the capacitor or inductor. Finally, fine-tuning and selection of coupling coefficients reflects a migration toward synchronization between two Josephson junction based-Wien circuits that imply the self-adaptation of the synapse when two types of synapses are active simultaneously.

Authors: Engelmann Sebastian
Published: August 2022

Transitions are a hot topic in educational science. At the same time, they have been addressed in educational literature for quite some time, and the multitude of guidebooks in particular have always been concerned with supporting transitions. This paper elaborates how a nineteenth-century guidebook formulates advice on the upbringing of young children to help facilitate the transition from the post-natal to the toddler stage, as well as providing a religious upbringing. The question is answered by a discussion of the selected guidebook Ueber Kleinkinder- Pflege by the pietist teacher Christian Heinrich Zeller.
Tellurite-filled hexa-circular-shaped PCF with highly nonlinearity, birefringent and near-zero dispersion profile for optical communications
Authors: Hasan Sohag Md. S. , Kabir K. H.
Published: August 2022

This manuscript focuses on devising a Tellurite-filled circular-timbered PCF that shows considerably highly birefringent and nonlinear characteristics. The impacts of numerous design parameters, such as birefringence (Br), nonlinear coefficients (NLC), confinement loss (CL), effective mode area (EMA), dispersion, numerical aperture (NA), etc. of the fiber are extensively inspected employing the commercially accessible and simulation- friendly COMSOL Software. Besides, the pertinent modal properties of the modeled fiber are rigorously characterized by operating the full-vector finite element method (FEM) with a perfectly matched layer (PML) boundary condition. The simulated findings affirm that the developed fiber exemplifies an ultra-high Br and NLC of 0.0924 and 18900 W-1Km-1 consecutively, at the operational wavelength of 1.55μm. Notably, the offered PCF also reveals a relatively lower CL, a negative-sloping dispersion and a higher EMA at the same wavelength. The pragmatic execution of the modeled fiber is expected to be doable applying the existing fabrication approaches and it can be applied in miscellaneous identical optical domains, namely polarization retention in long-distance communications, optical switching, sensor and laser layout, supercontinuum generation for frequency metrology and so forth.

Methodology for image retrieval based on binary spacepartitioning and perceptual image hashing
Authors: Hodovychenko Mykola A. , Antoshchuk Svitlana G. , Kuvaieva Varvara I.
Published: August 2022

The paperfocuses on the content-based image retrieval systems building. The main challengesin the construction of such sys-tems are considered, the components of such systems are reviewed, and a brief overview of the main methods and techniques that have been used in this area to implement the main components of image search systems is given.As one of the options for solving such a problem, an image retrievemethodology based on the binary space partitioning method and the perceptual hashing method is proposed. Space binary partition trees are a data structuresobtained as follows: the space is partitioned by a hyperplane into two half-spaces, and theneach half-space is recursively partitioned until each node contains only a trivial part of the input features. Perceptual hashing algorithms make it possible to represent an image as a 64-bit hash value, with similar images represented by similar hash values. As a metric for determining the distance between hash values, the Hamming distance is used, this counts the number of dis-tinct bits.To organize the base of hash values, a vp-tree is used, which is an implementation of the binary space partitioning struc-ture.For the experimental study of the methodology, the Caltech-256 data set was used, which contains 30607 images divided into 256 categories, the Difference Hash, P-Hash and Wavelet Hash algorithms were used as perceptual hashing algorithms, the study was carried out in the Google Colab environment.As part of an experimental study, the robustnessof hashing algorithms to modification, compression, blurring, noise, and image rotation was examined. In addition, a study was made of the process of building a vp-tree and the process of searching for images in the tree. As a result of experiments, it was found that each of the hashing algorithms has its own advantages and disadvantages. So, the hashing algorithm based on the difference inadjacentpixel values in the image turned out to be the fastest, but it turned out to be not very robustto modification and image rotation. The P-Hash algorithm, based on the use of the discrete cosine transform, showed better resistance to image blurring, but turned out to be sensitive to image compression. The W-Hash algorithm based on the Haar wavelet transform made it possible to construct the most efficient tree structure and provedto be resistant to image modification and compression.The proposed technique is not recommended for use in general-purpose image retrieval systems; however, it can be useful in searching for images in specialized databases. As ways to improve the methodology, one can note the improvement of the vp-tree structure, as well as the search for a more efficient method of image representation, in addition to perceptual hashing.
Control optimization of automatic multistage transmission in cityelectric bus
Authors: Shchur Ihor Z. , Kovtun Viacheslav O.
Published: August 2022

The threatening ecological situation in modern cities overloaded with traffic makes it expedient to replace buses with dieselengines with electric buses. In order to increase the energy efficiency of a drive of electric bus and, thanks to this, to expand its power reserve, the paper investigates the feasibility of using a multistage automatic transmission (AT). For research, the Electron E19101 electric bus was taken and two of its variants were considered –a studied one with a six-speed AT and a basic one with a single-speed transmission. For each of the options, the traction characteristics of the electric drive for different positions of the accelerator pedal were formed. Comparative studies of the operation of both variants of the electric bus were carried out by means of computer simulation. For this, computer models of all subsystems of electric buses, as well as external influences that resist movement and determine the load on the electric drive system, were built using the Energetic Macroscopic Representation method in the Matlab/Simulink environment. The application of the specified method makes it possible to simulate the movement of electric bus during a long-term of the adapted FTP-75 standard urban transport cycle. For the studied variant, the AT control system was developed with the aim of current selection of the optimal value of the gearbox transmission ratio, for which the maximum value of the efficiency of the electric drive system is obtained in specific driving conditions. The research results showed a 3.35% advantage in energy costs for movement in the applied transport cycle of the electric bus with the multistage transmission over the single-stage one. However, as also shown, this advantage increases to 5.3% during the buses move in the similar transport cycle at low speeds, which occurs in today's traffic-congested cities. In addition, the use of theATmakes it possible to reduce the rated power of the electric bus motor, increase its maximum traction force, which will ensure the possibility of moving with a full load on a large slope, as well as significantly increase the maximum speed of movement, which is important for suburban transportation.

The Effect of Education Groups on the Quality of Urban and Rural Compulsory Education: An Empirical Analysis Based on CEPS Data
Authors: Cheng Gang
Published: July 2022

We retrieved data from China Education Panel Survey (CEPS) and adopted the hierarchical linear model as well as the quantile regression method to examine the effect of education groups on the quality of urban and rural compulsory education. Student cognitive ability was cited as the evaluation index of education quality. According to the research findings, the overall effect of education groups on the quality of compulsory education is significantly positive, but there is urban-rural heterogeneity in this effect: the positive impact occurs only to urban member schools, while the education quality of rural member schools has not been improved by school grouping. In addition, there exists individual difference in this effect; school grouping significantly and negatively affects students from rural member schools and with medium and lower cognitive ability.
Rapid Archaeology of Human Constructions Within Interactive Digital Built Environments
Authors: Reinhard Andrew
Published: August 2022

Software is an architectural outcome of human labor which today houses the collective creative output of billions of people. Video games are a subset of software; they enable users to create their own built environments within a digital framework which can be shared with others for enjoyment, but these are later subject to abandonment and destruction. These digital constructions in synthetic, ephemeral spaces provide a unique challenge to archaeologists: how to document, preserve, and analyze archaeological evidence of human occupation of digital spaces, especially when that period of occupation can last mere minutes and can vanish from the digital landscape without a trace
Territorializing Whiteness
Authors: Cipolla Craig N , Quinn James , Levy Jay
Published: August 2022

This paper provides an archaeological perspective on the Boy Scouts of America, placing special emphasis on Scout camps occupying Mohegan lands in southeastern Connecticut (USA) and focusing on the alteration of Indigenous and Indigenous-colonial sites. Archaeological traces demonstrate how Scouts modified a range of stone features, both ancient and recent, and how they reorganized and redefined the land by naming and bounding their camps. Considering these patterns alongside Scout material culture, including the archaeological remains of Scout habitations, we discuss Boy Scout simulations of Indigenous and Indigenous-colonial histories. Drawing upon Indigenous knowledge and critique, we explore how Boy Scout camps “territorialize” whiteness. This involves the appropriation of Indigeneity as a means of escaping the trappings of late capitalist society, the misrepresentation of Indigenous history via well-worn tropes of unilineal evolution (where things always progress from simple to complex) and the denial of colonial plurality and of continued Indigenous presence on the land.

Published: August 2022

The mandible supports the oral cavity's soft tissues and teeth. The treatment of mandibular segmental defects must consider the missing component’s anatomic; the gold standard of mandibular reconstruction replaces the defect with vascularized bone unless the perioperative risk is extremely great owing to comorbid conditions. To achieve bony healing and restore the mandibular contour, rigid fixation of the free flap bone segments to the remaining mandible is important. The reconstruction made it easier to meet a wide range of treatment requirements. The most common reasons for reconstructive surgery today are defects after tumor surgery due to benign or malignant neoplasms of the oral cavity. First-line or adjuvant radiation plays a major role in today's multidisciplinary head and neck cancer treatment. When exposed to radiation, the mandible, in particular, is susceptible to osteoradionecrosis. So, this article review is to review the history of oromandibular reconstruction, the biomechanics of the mandible and summarizes the various reconstruction options available for the mandible, including defect classification, goals in reconstruction, donor sites, current reconstructive options, dental rehabilitation, and persistent associated problems.

It is among the findings that 2 (9%) of these companies received assurance only for environmental indicators, 9 (41%) for environmental and social indicators, 11 (50%) for environmental, social and economic indicators. In addition, all of the independent audit firms that give an independent assurance statement consist of three big audit firms within the big four. It has been found that there are 2 statements in which only the ISAE 3000 standard is used in the assurance engagement, 17 statements that the ISAE 3000 standard is used with the ISAE 3410 standard, 2 statements that the ISAE 3000 standard is used with the ISO 14064-3 standard, and 1 statement that the ISAE 3000 standard is used with the AA1000 standard.
Conclusion- It has been seen that even in the BIST Sustainability Index, which includes companies traded on Borsa Istanbul with a high level of sustainability performance, companies do not demand much assurance. Assurance statements that guide decision makers about the accuracy of non-financial information are an indicator of the transparency of companies. The assurance of this information by the companies will increase the reliability and reputation of the companies.

Open Science and COVID-19 RCTs v1
Authors: Borghi John
Published: August 2022

Open science is an umbrella term that covers a wide variety of efforts focused on making scientific research more transparent and accessible. Practices related to open science exist along a continuum of openness and an individual research effort can be more or less open along a number of dimensions- including the accessibility of related publications, availability of data and code, and application of techniques such as pre-registration that enhance transparency related to project aims and methods. Among the many motivations for adopting open science practices is the link between openness and reproducibility - the more transparent the research effort, the more easily its conclusions can be examined, evaluated, and built upon by others. This protocol outlines our methods for assessing the openness of randomized controlled trials (RCTs) related to the prevention and treatment of COVID-19. RCTs are commonly described as the "gold standard" of evidence in clinical research, which underlines the importance of their results are transparent.

Little is recognized regarding teachers’ beliefs about teaching with the appropriate framework integrating technology into language instruction, particularly during the COVID-19 outbreak. TPACK is a framework for apprehending knowledge domains required by EFL teachers nowadays. The preliminary study indicated that among the four English skills taught to middle school students, teaching writing was the most challenging. Therefore, it is essential to understand more about teachers’ beliefs regarding the practice of the TPACK framework in teaching writing. For that reason, This study aimed to (1) explore teachers' beliefs about the TPACK framework and (2) analyze classroom practices in teaching writing. This case study examined three teachers from different senior high schools in Indonesia of their beliefs about teaching writing with the TPACK framework and their classroom practices. A semi-structured interview was administered to explore their beliefs, while classroom observations focused on their classroom practices. The results demonstrated similarities and differences among teachers’ beliefs about learning objectives, teacher’s role, and assessment, while in classroom procedure and instructional material, teachers shared identical beliefs. Indeed, there was a majority of consistency between teachers’ beliefs and classroom practices of teaching writing with the TPACK framework. Despite its paramount consistency between teachers’ beliefs and classroom practices, the presence of the government to educate teachers is urgently needed, which can be in the form of virtual TPACK training. Then, this study may provide references for teaching writing with the TPACK framework that can adequately be applied during the COVID-19 outbreak and new normal.

Published: July 2022

The growing of internet and IoT application makes large number of devices will be connected each other to exchange data communication. IEEE made standard of WLAN technology to support the needs. But from the existing standard technologies, there are still deficiencies in delivering the data package for communication. IEEE 802.11ah was made as a new standard of Wi-Fi technology that supports wireless networking scenarios and solving the problem of capacity, coverage and power consumption in IoT era. The wireless access network is very attractive for best-effort data package transmission, but VoIP service on the wireless network is very critical due to its real-time communication characteristic. This research addresses the performance analysis of 802.11 ah standard against VoIP services. To determine the influence of node density in 802.11ah standard, the simulation is done by changing the number of station that access the channel via RAW mechanism. The simulation is performed using network simulator NS3 version 3.23. Based on the result, it can be concluded that the evaluation of IEEE 802.11ah standard in the node density scenario accompanied by the changing of RAW station and RAW group number, the use of MCS 5 with 2 MHz bandwidth resulting better network performance than MCS 7 with 1 MHz bandwidth. Using MCS 5 obtained delay value of 0.241761 s on average, the throughput value of 0,5648 Mbps on average, and the PDR value of 19.84 % on average.
Internet Voting Protocols: An Analysis of the Cryptographic Operations per Phase
Authors: Satizabal Cristina , Paez Rafael
Published: July 2022

Internet voting is a good option for Colombia thanks to the expansion of mobile technology throughout the country and the interest of the government to implement the e-voting. For this reason, we study the e-voting protocols to establish if any of them is suitable for Colombian elections. However some of them imply a great number of cryptographic operations and therefore a great computational cost for the devices, which sometimes exceed their capacity. In this paper, we determine the number of cryptographic operations per phase of four e-voting protocols: one based on blind signatures (Li, Hwang and Lai protocol), one based on mix nets (Meng protocol), one based on homomorphic encryption (EVIV protocol) and one used in real electoral processes (I-Voting for Estonian Elections). Then, we analyze the changes in the number of operations when the number of voters, number of votes, number of authorities and number of candidates increase for small, medium and large elections. Finally, we establish the protocol that imply a less number of cryptographic operations and is suitable for big electoral processes, such as congress elections in Colombia.

Published: August 2022

Determinar as principais causas de absenteísmo por problemas de saúde em Agentes de Segurança Penitenciária (ASPs) e relacioná-las com o envelhecimento. Estudo quantitativo, observacional e transversal, por meio de análise documental, realizado em penitenciárias masculina e feminina no interior paulista. Os dados foram analisados no software SPSS com significância de 5%. A amostra foi constituída de 79 ASPs com média de idade de 41,3 anos, tempo médio trabalhado de 11,5 anos e prevalência de absenteísmo de 18,3%. As principais causas de absenteísmo foram relacionadas a quadros emocionais, problemas ortopédicos e distúrbios gastrintestinais. Não se encontrou correlação entre idade cronológica e quantidade de afastamentos. Os dados obtidos muito se assemelham a outros estudos nacionais e internacionais, entretanto há escassez de evidências científicas abordando essa classe de trabalhadores, que carece de melhorias no cotidiano de seu exercício profissional, a fim de que desempenhe suas funções com maior dignidade.
