Authors: Manoharan Godfrey Bhonz , Thangasamy Sree Renga Raja
Published: February 2023

In this work, the transformer oil reclamation experimental test has been created utilising the physical-chemical reclamation technique and oil lifespan analysis using ANFIS algorithm. The significant of work is that it develops an ANFIS algorithm for estimating transformer life and analyzing transformer oil reliability. Rubber seed oil (mineral oil) is used in transformers to cool the substantial portion of the power transformer and decrease electrical ageing issues. These mineral oils interact chemically with the windings, suffering electrical and mechanical pressure owing to high temperatures over its power balance which leads to moisture and oxidation. In order to improve the performance of ageing oil, a physical and chemical reclamation approach with two primary steps, Coagulation and Adsorption, is used. Breakdown voltage, flash point, viscosity, and fire point are the important dielectric qualities of oil reclamation that will differentiate the performance between before and after reclamation when compared to diverse oil samples. The results of the work revealed that the physical-chemical reclamation process is enhanced the dielectric characteristics of the ageing oil, and the parameters of the reclaimed oil are utilised to predict the projected lifespan of the transformer service.

Published: February 2023

Peer-to-peer lending (P2PL) can be a source for Small and Medium Enterprises (SMEs) to obtain capital. As the public highly demands this method of capital obtainment, P2PL transactions have increased. The increase in transactions impacts the increase in existing risks, including the default status of borrowers. This risk is very detrimental to the lender as the owner of capital. The high risk will ultimately reduce the lenders’ trust in transacting through the P2PL platform. The article aims to examine the causes and consequences of the risks challenged by lenders, and provide solutions by implementing the appropriate risk management. This research used the descriptive qualitative method. The result shows that the primary causes of the occurring problems are the lack of government roles in supervising, regulating, and being responsible for these activities. An offered solution is protecting funds distributed by lenders with insurance to manage the default risk challenged by lenders.

Authors: Tich Tich Abdelghafour Slimane , Inel Foued , Khadem Mohammed
Published: February 2023

In this paper, a mobile robot (tricycle robot) and its kinematic and dynamic model are presented. Moreover, its simulation and model control are derived. For a mobile robot to be autonomous, it must perform command tasks and perceive the environment. In this context, navigation plays an important role in the interaction of the robot with its environment. It consists in the determination of possible trajectories by the robot to follow a predefined trajectory. To accomplish this task, our approach relies on the dynamic motion of the robot to generate admissible trajectories. The reference trajectory is first constructed based on a predefined trajectory. To eliminate the navigation problem, an optimization problem with constraints, it is necessary to reduce the difference between the predicted trajectory of the robot and the desired trajectory. Moreover, it is possible to control the behaviour of the robot by using a trajectory parameterized with the dynamic model and its control. Finally, the display of experimental results up to the implementation of the object detection.

Published: February 2023

Introduction. Cross-laminated timber (CLT) has started to win a market in Russia. Humidity plays an important role in ensuring the operational reliability of buildings based on timber structures. The lack of comprehensive studies on the influence of varying temperature and humidity actions, including atmospheric ones, hinders the development of CLT.

Aim. In this work, the influence of atmospheric actions on various types of CLT building structures was determined in order to amend the requirements in SP 64.13330.2017 for the design and protection of CLT structures.

Materials and methods. Samples of CLT wall panels and floor slabs manufactured as per the current regulatory documents were used as an object of research. Field tests were developed in order to determine the influence of atmospheric actions on the strength and elastic characteristics of CLT panels.

Results. Atmospheric actions have an adverse effect on the strength and elastic characteristics of CLT panels. The decrease in the strength and elastic characteristics varies for the samples of floor slabs and wall panels.

Conclusion. It is proposed that several recommendations given based on the experimental results on the resistance CLT to atmospheric actions are to be included in SP 64.13330.2017 for the design, manufacture, and construction of buildings using CLT structures.

Published: February 2023

Al-Qur'an is the word of Allah which was revealed to the Prophet Muhammad as a guide for mankind on earth. The Qur'an is the last book revealed by Allah swt as a source of Islamic law, a guide for human life to achieve prosperity in life in the world and the hereafter, including in caring for and nurturing children in order to get the highest degree before Allah swt. This study was conducted to examine how the role of the family, especially parents, teach the Qur'an to their children from an early age. The approach used is a qualitative approach, to construct reality, to understand what is hidden behind phenomena that are sometimes difficult to understand satisfactorily. The results of the study show that children's education is not only when they are born into the world, but begins when parents look for companions, while in the womb (prenatal), and after birth. Along with the development of technology and globalization, parents should always accompany, maintain and improve their children's ability to read and understand the content of the Qur'an. With the basic education that children have, it is hoped that they will be able to filter out the negative side brought by advances in technology and globalization today.

Published: February 2023

Islam obliges its followers to seek knowledge, where in the book of the Qur'an there is all knowledge from the smallest to the largest including knowledge related to living things in which it describes protein metabolism. The purpose of this study was to determine the Islamic view of protein metabolism. The author uses qualitative methods with sources in the form of books, journals, al-Qur'an, al-Hadith and sources from theses and articles from the internet. The results of the study show that metabolism is one of the most important processes in the body of living things, in order to produce the energy needed for survival. One example of metabolism is protein metabolism, which is a chemical and physical process that occurs in two phases, namely anabolism and catabolism where the change (anabolism) of proteins into amino acids and the breakdown (catabolism) of amino acids in proteins. A high source of protein that is needed by the body comes from animal protein as contained in QS. An-Nahl verse 5. In order to maintain protein metabolism, food must be in accordance with the portion. Therefore, Islam regulates food that is halal and good for processing in the body, including the quantity of food that is consumed. This was exemplified by the Prophet by putting food into the mouth in small portions to help digestion go well.

Chronic diseases with an inflammatory component are the major cause of mortality in the world. The treatment of inflammation is generally based on chemical drugs. Nutritionists recommend the use of food plants that might have anti-inflammatory effects. So, the phenolic compounds, chemical composition, acute toxicity, in vitro and in vivo anti-inflammatory activities and pain-relieving activity of a recipe extract based on the leaves extract of three food plants (Ceiba pentandra, Ipomoea batatas and Spinacia oleracea) were evaluated. The results showed that the yield of extraction was 20.7 % and revealed the presence of polyphenols (821.6 mg/100 g) and flavonoids (99.8 mg/100 g). The chemical composition gave: proteins 0.023 %, lipids 0,011 %, ash 0.013 %, fibers 0.011 % and assimilables carbohydrates 0.026 %. The acute toxicity test did not cause any mortality, nor any sign of toxicity at the dose of 5000 mg/Kg/bw. In vitro anti-inflammatory test showed that the plants extract, at the concentrations of 150 and 250 µg/mL had an inhibitory effect, respectively of 65.63% and 86.97%. For in vivo anti-inflammatory test, at the doses of 400 and 800 mg/Kg/bw, the extract has an optimum inhibition of 79.95% and 53.62%, on a mice paw edema, at the fourth hour after injection. The pain test showed inhibitions of 94.74%; 98.25% and 100% at the respective doses of 300, 600 and 1200 mg/Kg/bw. The results therefore suggest that the recipe of the three food plants has an anti-inflammatory activity, certainly due to the presence of polyphenols and flavonoids.

Alfabetização: um desafio para um novo tempo Literacy: a change for a new time
Authors: Castelo Branco de SANTANA Fabiana
Published: February 2023

Diante da sociedade atual em que a escola precisa estar apta para formar indivíduos prontos para assumirem novos saberes, o conceito de alfabetização supera a definição de ser apenas a aquisição da técnica de decifração e codificação dos signos linguísticos. Nesse sentido, ser alfabetizado apresenta-se cómo a possibilidade de utilização de tais conhecimentos em benefício de formas de expressão e comunicação em um determinado contexto cultural. Por conseguinte, este artigo traz um embate entre duas concepções de ensino antagônicas; a empirista, observada através da experiência de estágio, e a construtivista, defendida neste trabalho. A partir daí, é realizada uma reflexão deste confronto, vislumbrando iniciativas pedagógicas que valorizem a criança como sujeito de sua própria aprendizagem.

CREATING CLAUSTROPHOBIA IN CHRISTOPHER NOLAN’S DUNKIRK
Authors: Lankauskaitė Viktorija
Published: February 2023

Christopher Nolan’s cinema and its immersive quality is appreciated by audiences and critics alike, and already analysed by researchers, often mentioning “claustrophobia” as a feeling encountered in his films. However, a number of extensive explorations of his work, and filmmaking in general, leave the creation of claustrophobia in cinema undiscussed. Thus, the article aims to fill the gap and investigate his 2017’s film Dunkirk, since this account of the historical event during the World War II has often been described as “claustrophobic”. Cinematic space and time, the way the medium can be used to create certain feelings, as well as the properties of Nolan’s work are examined. Space and time manipulation, the use of IMAX for immersion, interchanging aspect ratios, and the idea of contrasts are responsible for the claustrophobic atmosphere in the film. The study could be useful for filmmakers and creatives, as well as for audiences interested in what shapes their experience of the story they see on screen.
Principal-component Interferometric Modeling (PRIMO), an Algorithm for EHT Data. I. Reconstructing Images from Simulated EHT Observations
Authors: Medeiros Lia , Psaltis Dimitrios , Lauer Tod R. , Özel Feryal
Published: February 2023

The sparse interferometric coverage of the Event Horizon Telescope (EHT) poses a significant challenge for both reconstruction and model fitting of black hole images. PRIMO is a new principal components analysis-based algorithm for image reconstruction that uses the results of high-fidelity general relativistic, magnetohydrodynamic simulations of low-luminosity accretion flows as a training set. This allows the reconstruction of images that are consistent with the interferometric data and that live in the space of images that is spanned by the simulations. PRIMO follows Monte Carlo Markov Chains to fit a linear combination of principal components derived from an ensemble of simulated images to interferometric data. We show that PRIMO can efficiently and accurately reconstruct synthetic EHT data sets for several simulated images, even when the simulation parameters are significantly different from those of the image ensemble that was used to generate the principal components. The resulting reconstructions achieve resolution that is consistent with the performance of the array and do not introduce significant biases in image features such as the diameter of the ring of emission.
Generic placement of the African flea beetle Polyclada maculipennis Bryant and the possible occurrence of the genus Procalus Clark in sub-Saharan Africa (Coleoptera, Chrysomelidae, Galerucinae, Alticini)
Authors: D'Alessandro Paola , Biondi Maurizio
Published: February 2023

Polyclada Chevrolat and Procalus Clark are flea beetle genera (Coleoptera, Chrysomelidae, Galerucinae, Alticini). Polyclada is endemic to the Afrotropical region, while Procalus has never been described outside of the Neotropical region. The new combination Procalus maculipennis (Bryant, 1942), comb. nov. is proposed for Polyclada maculipennis Bryant, 1942. Its plausible type locality is Venezuela, and not Cameroon, as recorded on the labels of the type material, and hence the occurrence of P. maculipennis in Africa is questionable.

Well-posedness of generalized Stokes-Brinkman equations modeling moving solid phases
Authors: Kumankat Nisachon , Wuttanachamsri Kanognudge
Published: February 2023

Fluid flow through a free-fluid region and the adjacent porous medium has been studied in various problems, such as water flow in rice fields. For the problem with self-propelled solid phases, we provide a generalized Stokes equation for the free-fluid domain and the Brinkman equation in a macroscopic scale due to the movement of self-propelled solid phases rather than a single solid in the porous medium. The model is derived with the assumption that the porosity is not a constant. The porosity in the mathematical model varies depending on the propagation of the solid phases. These two models can be matched at the free-fluid/porous-medium interface and are developed for real world problems. We show the proof of the well-posedness of the discretized form of the weak formulation obtained from applying a mixed finite element scheme to the generalized Stokes-Brinkman equations. The proofs of the continuity and coercive property of the linear and bilinear functionals in the discretized equation are illustrated. We present the existence and uniqueness of the generalized Stokes-Brinkman equations for the numerical problem in two dimensions. The system of equations can be applied to fluid flow propelled by moving solid phases, such as mucus flow in the trachea.
Research on en route capacity evaluation model based on aircraft trajectory data
Authors: Ren Jie , Qu Shiru , Wang Lili , Wang Yu , Lu Tingting , Ma Lijing
Published: February 2023

For the sake of refined assessment of airspace operation status, improvement of the en route air traffic management performance, and alleviation of the imbalance of demand-capacity and airspace congestion, an en route accessible capacity evaluation model (based on aircraft trajectory data) is proposed in this paper. Firstly, from the perspective of flux, the en route capacity is defined and expanded from a two-dimensional concept to a three-dimensional concept. Secondly, based on the indicators of spatial flow and instantaneous density, an evaluation model of en route capacity is given. Finally, a case study is performed to validate the applicability and feasibility of the model. Results show that the en route accessible capacity, instantaneous density, and spatial flow can describe the temporal and spatial distribution of air traffic flow more precisely, as compared to the conventional indicators, such as route capacity, density, and flow. The proposed model envisages three innovations: (ⅰ) the definition of airspace accessible capacity with reference to capacity of road traffic, (ⅱ) the computation model for flux-based airspace accessible capacity and en route accessible capacity, and (ⅲ) two indicators of en route characteristics named instantaneous density and spatial flow are introduced for evaluating the micro-state of the en route. Furthermore, because of the capacity depiction of the spatial and temporal distribution of air traffic congestion within an airspace unit, this model can also help air traffic controllers balance the distribution of traffic flow density, reduce the utilization rate of horizontal airspace, and resolve flight conflicts on air routes in advance.
A fuzzy logic and DEEC protocol-based clustering routing method for wireless sensor networks
Authors: Subramani Neelakandan , Mardani Abbas , Mohan Prakash , Mishra Arunodaya Raj , P Ezhumalai
Published: February 2023

Power-efficient wireless sensor network routing techniques (WSN). Clustering is used to extend WSNs' lifetimes. One node act as the cluster head (CH) to represent the others in communications. The member nodes are less important than the cluster hub (CH) in the clustering procedure. Fuzzy techniques based on clustering theory may provide evenly distributed loads. In this study, we provide a fuzzy-logic-based solution that factors in distance to base station (BS), number of nodes, remaining energy, compactness, distance to communicate within a cluster, number of CH, and remaining energy. Fuzzy clustering has a preliminary and final step. First, we select CH based on distance to the base station (BS), remaining node vigor, and node compactness. In the second phase, clusters are created by combining nodes that aren't already in a CH, using density, outstanding vigor, and detachment as limitations. The proposed solution increases load balancing and node longevity. This work provides a unique hybrid routing technique for forming clusters and managing data transfer to the base station. Simulation findings confirm the protocol's functionality and competence. Reduced energy use keeps network sensor nodes online longer. The framework outperforms Stable Election Protocol (SEP), hybrid energy-efficient distributed clustering (HEED), and Low Energy Adaptive Clustering Hierarchy (LEACH). Using the nodes' energy levels to create a grid pattern for the clusters gave four clusters. In addition, the proposed method has a 4347%, 41.46%, 39.26%, 37.57% and 35.67% reduction in average energy consumption when compared with the conventional algorithms. The proposed technologies could increase the network's lifetime, stability interval, packet transfer rate (throughput), and average energy. The suggested protocol is at least 50% better in every statistic that was looked at, such as network lifetime, stability interval, packet transmission rate (throughput), and average energy use.
L’héritage d’Henri Poincaré en physique

Où l’on revient, à la lumière des connaissances actuelles, sur certains apports déterminants de Poincaré : le chaos, l’importance des probabilités – et, en partie, la relativité ; ses positions novatrices comme ses positions conservatrices ; ses apports en physique pratique (TSF, théorie du signal) aussi bien qu’en physique théorique. Poincaré fait partie des savants, assez rares, qui ont beaucoup apporté à la fois à la physique et aux mathématiques.
La mesure du diamètre des étoiles
Authors: Lequeux James
Published: February 2023

Dès 1851, Hippolyte Fizeau réalise que l’on pourrait mesurer par interférométrie le diamètre apparent des étoiles en découpant avec deux diaphragmes placés devant l’objectif d’une lunette ou d’un télescope deux parties de la lumière reçue de l’étoile et en faisant interférer ces deux faisceaux. Mais il ne publie cette idée qu’en 1868 sous la forme d’une simple remarque. En 1873-1874 Édouard Stephan la met en application avec le télescope de 80 cm de diamètre de l’Observatoire de Marseille, pour constater qu’aucune des étoiles qu’il observe n’est résolue. Puis elle est utilisée avec succès par Albert A. Michelson en 1891 et par Maurice Hamy en 1898 pour mesurer le diamètre apparent des satellites de Jupiter, et en 1895 par Karl Schwarzschild pour déterminer la séparation entre les composantes d’étoiles doubles. Ce n’est qu’en 1920 que Michelson et Francis G. Pease parviennent à mesurer ainsi le diamètre de Bételgeuse. Puis la méthode est en sommeil jusqu’à ce qu’elle soit remise d’actualité sous une forme différente en 1956 par Robert Hanbury Brown et Richard Q. Twiss, puis sous sa forme initiale en 1974 par Antoine Labeyrie. Elle est aujourd’hui en plein essor, avec au moins 12 interféromètres optiques spécialisés dans le monde.
Les lentilles à échelons de Fresnel
Authors: Guigueno Vincent
Published: February 2023

La lentille à échelons de Fresnel va remplacer le réflecteur parabolique en usage jusqu’alors dans les phares. Avec un dispositif rotatoire et une source d’éclairage innovants eux aussi, elle va permettre une évolution de grande ampleur dans la signalisation maritime sur les côtes françaises. Elle avait déjà été imaginée quelques décennies auparavant par Buffon, mais c’est Fresnel, en ayant l’idée de la faire en plusieurs morceaux, qui lui permet une utilisation immédiate. Le texte est agrémenté de figures (auteur : Manuel Luque) permettant de visualiser le parcours d’un rayon lumineux, et les deux réfractions successives dans la lentille. Les lentilles à échelons sont toujours utilisées dans les phares maritimes, et trouveront une utilisation que Fresnel n’avait pas imaginée : les phares automobiles.

The concept of cloud computing makes it possible to have a shared pool of reconfigurable computing resources that can be deployed and released with little involvement from administration work or service providers. Cloud computing makes this possible. The communication among the nodes is possible with the help of internet. All users are able to use the services of cloud. The small-scale industries are really happy to use the cloud services. The attackers are degrading the performance of services, and also the users are not receiving the response. This paper presents the imprint of cloud computing. Flooding attacks or the DoS attack is one attack that reserves the communication resources in network, and the rest of the attacks, like Sybil attack, misguide the users, and also it is not easy to identify the exact identification of the sender. The security schemes are able to remove attacker infection, and on the basis of that, it is possible to design better schemes against attackers in the cloud.

Published: February 2023

Local perceptions in the definition of cultural landscapes have been on the radar of the scientific community for a long time, but very few studies have focused on integrating this information into heritage and planning practices. The purpose of this paper is to demonstrate, with a practical example, how to do so through a Public Participation GIS (PPGIS) application. In this study, a landscape approach and participatory mapping framework were tailored to a case study area in the south of Italy, where an online map-based survey was shared with the public. The survey results illustrate how the application effectively brought to the fore local heritage perceptions as relevant sources for future potential spatial planning strategies.

Authors: Clark M'Kaila J. , Rajabion Lila
Published: February 2023

The internet of things' (IoT) fast-growing development and adoption are undeniable. Although the IoT development is moving at a fast rate, the security of these technologies is not keeping up. Lack of security infrastructure on the internet of things is due to such security measures being excluded from the average company business plan and the lack of security configurations established. The increasing need for robust security architecture is needed to address said vulnerabilities. How do the internet of things companies create a dynamic security approach to defend and combat threats while also being flexible to accommodate future technological advancements? This paper will answer this question by addressing the strategic approach to developing a strong IoT security infrastructure that promotes confidentiality, integrity, and availability with dynamic elements that allow for future developments to address new security concerns. This research question will be answered through analysis of extensive thematic literature review.

IoT devices generate enormous amounts of data, which deep learning algorithms can learn from more effectively than shallow learning algorithms. The approach for threat detection may ultimately benefit fog computing or fog networking (fogging). The authors present a cutting-edge distributed DL method for detecting cyberattacks and vulnerability injection (CAVID) in this paper. In terms of the evaluation metrics tested in the tests, the DL model performs better than the SL models. They demonstrated a distributed DL-driven fog computing CAVID approach using the open-source NSL-KDD dataset. A pre-trained SAE was utilised for feature engineering, whereas Softmax was employed for categorization. They used parametric evaluation for system assessment to evaluate the model in comparison to SL techniques. For scalability, accuracy across several worker nodes was taken into consideration. In addition to the robustness, effectiveness, and optimization of distributed parallel learning among fog nodes for enhancing accuracy, the findings demonstrate DL models exceeding classic ML architectures.

Published: February 2023

Estimating the energy and memory consumption of machine learning(ML) models for intrusion detection ensures efficient allocation of system resources. This study investigates the impact of supervised ML algorithms on the energy and memory consumption of intrusion detection systems. Experiments are conducted with seven ML algorithms and a proposed ensemble model, utilizing two intrusion detection datasets. Pearson correlation coefficient(PCC) and Spearman correlation coefficient are employed for the selection of optimum features. Regarding energy consumption, the findings reveal that the PCC with the UNSW-NB15 dataset uses the least amount of DRAM and CPU power. For ML methods, SVM utilizes the highest energy for both feature selection methods and datasets. Concerning memory consumption, the results show that decision tree uses the most current memory with PCC on the UNSW-NB15. The proposed ensemble model demonstrates the highest performance. These findings offer practical guidelines to ML experts when choosing the optimum model with the most efficient utilization of energy and memory.

Published: February 2023

One of the emerging areas is knowledge co-creation, and more specifically, in an educational context, curriculum co-creation. The ability to solicit feedback, reactions, suggestions, and improvements with regards to courses and educational programs from students is an interesting and promising one, but a concept which requires that existing norms and practices be put aside to allow students to share in the evaluation, revision, and design process, together with instructors and administrators. This paper examines the foundations of curriculum co-creation, including its educational theory foundations, critical variables and considerations, and a review of recent programs and initiatives. A framework of the key curriculum co-creation variables is presented, followed by suggestions for future research.

Satellite images play an important role for capturing Earth's surface. Using satellite images land cover monitoring could be done through which the modification or changes on land surface could be identified. Comparison can be made on the basis of past satellite image analysis, which helps to identify the changes that are occurring or have already occurred. Although there exist many techniques for land cover monitoring, proper land cover identification and detection of changes on the land cover is still a challenge. In the recent years, machine learning techniques have been utilized in distinct areas of image analysis and resulted in positive outcomes. Hence, in this paper, four supervised machine learning algorithms (i.e., support vector machine [SVM]), neural network [NN], maximum likelihood [MLC], and parallelepiped [PP] algorithms) have been utilized for land cover identification and detecting the amount of changes that have occurred in the individual land cover classes.

Published: February 2023

In the present investigation, Y3+ doped (5 wt. %, 10 wt. %, and 12 wt. %) cerium sesquisulfides (Ce2S3) nanoparticles (NPS) were synthesized by a simple chemical precipitation method. Thin films of Y3+:Ce2S3 NPs achieved on ITO (indium tin oxide) substrate. XRD (X-ray diffraction) patterns were used to estimate the size of the NPS, morphology index, texture coefficient, and lattice constants. The crystallite size was found to be in the range of 18-34 nm. UV-visible spectral studies were carried out in order to understand optical absorptivity, and optical band (Eg) of the as-synthesized nanostructures (NS). It has been observed that the red shift in the optical absorptivity and Eg value varies between 3.45 eV to 2.59 eV. Morphology and the presence of Y+3 were investigated by scanning electron microscope (SEM) and energy dispersive X-ray studies (EDX). However, agglomerated spherical-shaped NPs and homogeneous dispersion of Y3+ were observed in EDX analysis. Chemical constituents and nature of the doped NS were examined by X-ray photoelectron spectroscopy (XPS), and binding energies matched with Y 3d3/2, Y 3d5/2, Ce 3d3/2, Ce 3d5/2, O1s, C1s peaks. Y3+: Ce2S3 (12 wt. %) NS subjected for dielectric property studies in the frequency range of 10 Hz-10 MHz at room temperature (RT). High dielectric permittivity (Ɛ), and very low dielectric loss (tan δ) were observed at low frequency for 12 wt. % Y3+:Ce2S3 NS as compared with other doped NS. The as-synthesized NS can be used for high dielectric permittivity, low dielectric loss, and capacitor-related applications.
