In this paper, a simple and efficient element is proposed for the free vibration and buckling analysis of FGM beams. This element is formulating, based on Timoshenko beam theory. The assumption of constant shear strain in the element reduces the number of unknowns in addition to improving the efficiency of the new element. The performance of the new element is evaluated with the help of several benchmark tests. First, the accuracy and convergence rate of the proposed element response in the analysis of free vibration and buckling of the beam are investigated separately by exponential variations of the modulus of elasticity and density in each of the beams' thickness and length. Subsequently, the element's ability to model material variations in both longitudinal and thickness directions of the beam will be measured simultaneously. For comparison, the answers of good elements of other researchers are available in each of the numerical tests. These tests will prove the high accuracy and rapid convergence rate of the proposed element.

In this paper, a wideband microstrip hybrid coupler designed, simulated, built and tested. These couplers have advantage of easy fabrication, lightweight and incorporation with other microwave devices and validated using 3D planar electromagnetic softwares like Sonnet Suites. The final design is composition of two parallel lines with symmetric slits and a center slot. Directional coupler is designed and simulated to operate in the frequency range from 1 GHz to 5 GHz with 2.4 Ghz coupling -10 dB return loss bandwidth between 1.6 - 4 GHz. The fabricated coupler shows good agreement between measured and simulated results with very low isolation characteristics. Four symmetric orthogonal U-Shaped structures at the center of the coupling region distinguishes the proposed design with other works. It makes significant improvement in calculation duration thereby achieving lower response latency and lowers the possible manufacturing errors compared with previously published similar works.

For electrical machines and power circuits to operate at high performance, it is important to control them at the optimum point. So, in this study, a flexible closed-loop (FCL) PID and PID FUZZY study is presented. Different from other studies, different controls can be activated for different positions and durations within the total operating time of the motor. At the same time, by applying four inputs for fuzzification in the designed fuzzy logic control section, 3 different outputs are provided to the PID control in three defuzzification sections. So, Dynamic Fuzzy logic interactivity is ensured with PID on load. This, unlike other PID FUZZY controllers, provides a more effective application of error and error change to the system. In the second chapter, DC motors and controls are explained. In the third chapter, designed controls and dc motor applications are made. The results obtained in practice reveal the effectiveness of the proposed system after compared with conventional P, PI and PID.
Améliorer la prévision de température en montagne par des descentes d'échelle
Authors: Arnould Gabriel , Dombrowski-Etchevers Ingrid , Gouttevin Isabelle , Seity Yann
Published: November 2021

En montagne, la prévision du temps et d'aléas aussi dangereux et localisés que les avalanches requiert une modélisation de l'atmosphère à haute résolution spatiale. Palliant des simulations coûteuses, des méthodes de descente d'échelle ont été appliquées pour produire des champs météorologiques à 500 m de résolution, sur les massifs alpins, à partir des prévisions issues du modèle Arome à 1,3 km. L'évaluation s'est concentrée sur la température à 2 mètres, paramètre météorologique clé pour la physique du manteau neigeux. Une descente d'échelle exploite un profil thermique environnemental. Sa pertinence est démontrée dans certaines configurations météorologiques, mais les erreurs intrinsèques au modèle Arome contraignent son potentiel.

In mountain areas, a numerical model with high spatial resolution is necessary to forecast the local meteorological conditions and the natural hazard such as avalanches. To limit time-consuming computations, downscaling methods were used to produce meteorological fields within a grid spacing of 500 m in the Alps from the Météo-France 1.3 km resolution forecast model (Arome). The evaluation focuses on the 2 meters temperature which is a key variable in snowpack changes. One method employs a correction based on a local vertical temperature lapse rate. Its impact is quite positive in some atmospheric conditions but remains limited by the Arome bias.

Distinct partitions and overpartitions
Authors:   DEPARTMENT OF MATHEMATICS UNIVERSITY OF CRAIOVA, ROMANIA, MERCA MIRCEA
Published: November 2021

In 1963, Peter Hagis, Jr. provided a Hardy-Ramanujan-Rademacher-type convergent series that can be used to compute an isolated value of the partition function $Q(n)$ which counts partitions of $n$ into distinct parts. Computing $Q(n)$ by this method requires arithmetic with very high-precision approximate real numbers and it is complicated. In this paper, we investigate new connections between partitions into distinct parts and overpartitions and obtain a surprising recurrence relation for the number of partitions of $n$ into distinct parts. By particularization of this relation, we derive two different linear recurrence relations for the partition function $Q(n)$. One of them involves the thrice square numbers and the other involves the generalized octagonal numbers. The recurrence relation involving the thrice square numbers provide a simple and fast computation of the value of $Q(n)$. This method uses only (large) integer arithmetic and it is simpler to program. Infinite families of linear inequalities involving partitions into distinct parts and overpartitions are introduced in this context.

Tools that focus on static code analysis for early error detection are of utmost importance in software development, especially since the propagation of errors is strongly related to higher costs in the development process. Formal Concept Analysis is a prominent field of applied mathematics that uses conceptual landscapes to discover and represent maximal clusters of data. Its expressive visualization method makes it suitable for exploratory analyses in different fields. In this paper we present a Formal Concept Analysis framework for static code analysis that can serve as a model for quantitative and qualitative exploration and interpretation of such results.
Popular Differences for Right Isosceles Triangles
Authors: Kovač Vjekoslav
Published: November 2021

For a subset $A$ of $\{1,2,\ldots,N\}^2$ of size $\alpha N^2$ we show existence of $(m,n)\neq(0,0)$ such that the set $A$ contains at least $(\alpha^3 - o(1))N^2$ triples of points of the form $(a,b)$, $(a+m,b+n)$, $(a-n,b+m)$. This answers a question by Ackelsberg, Bergelson, and Best. The same approach also establishes the corresponding result for compact abelian groups. Furthermore, for a finite field $\mathbb{F}_q$ we comment on exponential smallness of subsets of $(\mathbb{F}_q^n)^2$ that avoid the aforementioned configuration. The proofs are minor modifications of the existing proofs regarding three-term arithmetic progressions.

Comparing the Borich model with the Ranked Discrepancy Model for competency assessment: A novel approach
Authors: Narine Lendel , Harder Amy
Published: November 2021

In 1980, Borich presented a new model that allowed errors in an individual’s judgment of self-proficiency to be offset by considering the perception of a group. The model relied upon the calculation of means for competency items measured with ordinal scales, an approach subject to debate in modern times. The purpose of our study was to explore the use of a novel approach we developed, the Ranked Discrepancy Model (RDM), as an alternative method to the Borich model for determining training needs. Data obtained from an online survey of extension professionals employed by a land-grant university in the United States was used to compare the training needs identified by applying the Borich model with those identified by applying the RDM. A very strong and statistically significant correlation existed between the scores derived from using both models, demonstrating a high level of consistency between models. Researchers conducting competency research should consider adopting the RDM given its suitability for delivering results that closely resemble findings from the Borich model while providing improved rigor in methods and increased detail about training needs.
Saudis’ Attitudes Towards Their Dialects: A Keyword Technique
Authors: Alhazmi Laila , Alfalig Hanady
Published: November 2021

Language attitude research uncovers perceptions about the diversity of languages and dialects. It follows how such diversity is stereotypically perceived, which influences the usage of dialects among people. Therefore, diverse contexts, such as Saudi Arabia, necessitate research attention to reveal how stereotypes Saudis hold towards their dialects might affect their usage. Little research has focused on the broad language attitudes in Saudi Arabia, and none of the previous studies have identified the major language attitudes in the region using keyword technique. Using an open-ended questionnaire, the present study identifies the major attitudes regarding the main dialects in the country: Central, Northern, Southern, Eastern and Western dialects. The names of the dialects were represented conceptually in the questionnaire. Seventy-eight participants were recruited for the study. First, they were asked to write down their first impressions of Saudi dialects. Second, they were asked to name the most dominant spoken dialect. Eight evaluative themes emerged from the study: affective positive, affective negative, linguistic features, awareness of language variation, cultural association, geographical association, tradition and modernity. Each of them reflects vivid stereotypical suppositions of the dialects. Furthermore, 68% of participants perceived Najdi as the most dominant dialect in Saudi Arabia.

Electrical, electrochemical and structural studies of a chlorine-derived ionic liquid-based polymer gel electrolyte
Authors: Gupta Ashish , Jain Amrita , Kumari Manju , Tripathi Santosh K
Published: November 2021

In the present article, an ionic liquid-based polymer gel electrolyte was synthesized by using poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) as a host polymer. The electrolyte films were synthesized by using the solution casting technique. The as-prepared films were free-standing and transparent with good dimensional stability. Optimized electrolyte films exhibit a maximum room-temperature ionic conductivity of σ = 8.9 × 10−3 S·cm−1. The temperature dependence of the prepared polymer gel electrolytes follows the thermally activated behavior of the Vogel–Tammann–Fulcher equation. The total ionic transference number was ≈0.91 with a wider electrochemical potential window of 4.0 V for the prepared electrolyte film which contains 30 wt % of the ionic liquid. The optimized films have good potential to be used as electrolyte materials for energy storage applications.
Industrial parks in Ukraine: current situation and development prospects in the conditions of digitalization of innovative economy
Authors: BASHYNSKA Iryna , FILIPPOV Volodymyr , CHERNIAHINA Nataliia
Published: November 2021

Introduction. Industrial park (cluster) is a relatively new form of economic organization, which in many developed countries plays a significant role in shaping and ensuring the competitiveness of countries and territories. Despite the economic viability of economic clusters, clusters have not yet become widespread in Ukraine, in contrast to highly developed countries. The modern development of the innovative economy, combined with comprehensive digitalization, makes its adjustments – opportunities and risks – in the functioning of economic entities of all forms and levels, which must be considered.
The purpose of the paper is to study the current state of industrial parks in Ukraine and to analyse the prospects for their development.
Results. In the article, the authors explored the innovative economy's digitalization features and provided its definition. They assessed the current state of industrial parks in Ukraine, identified fully operational parks, have high-quality infrastructure facilities, and have residents with actually operating plants. Identified the reasons for their inefficient functioning and developed recommendations for improving the formation and operation of industrial parks in Ukraine, using digital tools of the innovative economy. It was noted that the innovative component of successful implementation in practice of a regionally integrated approach is the addition or expansion of activities through narrower (specialized) approaches that have a clear, practical focus. Such specialization can be the development of industrial tourism. The second way of efficiency of an industrial park is its unique specialization, for example, the chemical industry. Each focus or specialization should be evaluated and determined in each case.
Conclusion. Industrial parks are an essential tool of the country's economy, which can make the country a leader; however, this form of organization carries risks, the main of which is the imitation of the industrial park for illicit enrichment. Therefore, it is necessary to further improve the mechanism of regulation and especially control by the state over the activities of industrial parks.
Statistical model for evaluation of the impact of climatic conditions on the crops production: the regional aspects
Authors: POSHYVALOVA Olena
Published: November 2021

The work examines the statistical model for evaluation of the impact of climatic conditions on the crops production in Ukraine. The conducted content analysis of academic literary sources enables to arrive at conclusion that the majority of Ukrainian scholars consider changes in climatic zones of Ukraine a positive trend for crops production. It must be emphasized, nonetheless, that the increase in natural heat provision for crops production against the backdrop of a significant reduction in average annual precipitation considerably diminishes the sizes of cultivated and harvested areas, gross yield and overall crop yield of basic crops and perennial plantings. To perform calculations on key statistical indicators of crops production the following tools have been employed: methods of analysis of absolute, relative and average values; methods of elaboration and study of groupings; methods of analysis of the structure of statistical populations; methods of cross-impact analysis of indicators; methods of trend studies. The analysis concerned the dynamics of change in statistical indicators of crops production in Kherson oblast over the period of 1990–2019: gross yield of cereal and leguminous crops; total harvesting area of cereal and leguminous crops; wheat yields; cereal and leguminous crops production per capita. Periods of diverse degrees of occurrence of atmospheric precipitation in Kherson oblast according to the level of liquid saturation have been grouped: dry, medium, humid. It has been proved that winter wheat yields are affected by the following factors: size of the cultivation area and average annual precipitation. It is established that the digitalization of the agriculture contributes to the decrease in pressure on land and water resources, provision of conditions for “clean”, sustainable and eco-friendly agricultural products, increase in gross yield of crops, provision of conditions for efficient use of resources, capability of Big Data processing. Prospects for further research lie in elaboration of a multi-factor non-linear modeling of winter wheat yield with account for the factors of humus and soil pH; average annual atmospheric temperature, etc.

Development of a web-resource today is a very frequent and not always simple task. Especially if we are not talking about a static one-page website, but about a dynamic web application with an unlimited number of pages, as well as the ability to withstand heavy loads, typical of such projects. To solve these problems, there are very few ready-made solutions. Of the best ones, perhaps, only WebDSL can be distinguished, but even it has a number of drawbacks inherited from the Java project implementation language, such as, for example, low flexibility, high performance costs and the need to install a java-machine. The development process was carried out using a relatively low-level C++ general purpose programming language, which saved the project from the problems that its competitors faced, ensured high interpreter performance and cross-platform system-wide. The authors described in detail the selected means of the meta-management of the access rights of the BlockSet project, as well as the syntax of their use in the declarative highly abstract subject-oriented language BML, using simple and accessible examples to demonstrate the conciseness, but the constructiveness of the selected syntax solutions. The results obtained are of great value, as they significantly simplify the further process of administering a web resource, which is also one of the main tasks of the BlockSet project. Thus, the BML language, together with the system of access rights, provides flexible, powerful, and at the same time fairly simple and understandable methods for organizing the required system, which corresponds to the project’s paradigms on flexibility and a low threshold of entry, and also significantly optimizes the development process.

All enterprises engaged in exploration activities on the territory of the Russian Federation, are facing the need to formulate tasks for the mine surveyor service and control their execution. It affects enterprise’s workflow process. Due to it, a problem of organization of efficient document processing in electronic document management systems (timely identification of documents containing mine surveying data) takes place. The article presents possible solution of this problem – automated document classification system into EDMS in the form of optional add-on for 1C:Document Management. Within the classification system creation a preprocessing script for primary document texts, including cleaning, lemmatization, stop words removing, as well as preparation of input features for the classifier were developed and implemented. Applicability of different machine learning algorithms to solution of considering classification problem was studied, the values of hyperparameters providing the highest value of the ROC AUC metric were determined. The quality of all obtained models was assessed using metrics Precision, Recall and F-measures, the stability of the classification quality to changes in the input data was investigated. The identified problem of instability of classification results was solved by building and implementing a machine learning model in the form of ensemble of classifiers. Classification model (an ensemble of clusters) was tested on the set of real documents of Gazprom nedra Ltd; classiffication quality on the test sample by ROC AUC metric was 0,91. Except the classification module itself, developed system contains the storage database for learning outcomes, function library for organization of work with the database and API interfaces allowing to process classification requests, coming from external systems. These API interfaces, in particular, implement the ability to load saved trained models, validate data coming from external systems, preprocess input text documents, train new models and assess their quality, save both trained models and the results of their testing. Also the possibility of the additional training of the models on a new data was realized.

This study formulates an inventory model with limited storage capacity under the condition of order-size dependent trade credit. Shortages are allowed and partially backlogged. The objective of this study is to determine the optimal replenishment cycle length, the optimal fraction of no shortage, and whether retailers should choose to rent an extra warehouse to store more items, such that retailers’ total annual profit is maximized. We prove the global optimally of objective functions and derive the closed-form optimal solution. Some numerical examples are presented to illustrate the applicability of the proposed model. Sensitivity analysis is carried out and managerial insights are obtained. We find that if retailers’ own warehouse capacity is relatively small, they always benefit from enlarging order quantity and renting an extra warehouse; meanwhile, suppliers further prolong the credit period is beneficial for both parties. On the contrary, as retailers’ own warehouse capacity increases and exceeds the optimal order quantity under that of without capacity constraints, adopting the same replenishment strategy as that without capacity constraints is profitable for retailers. Our results also reveal that other model parameters (e.g., ordering cost, inventory holding cost, shortages cost, backordering rate, etc.) have a significant impact on retailers’ optimal decisions.

Pour travailler les compétences en socialisation, autonomie et communication, un groupe cible de 11 enfants (âge moyen : 9 ans 8 mois) utilisent une tablette tactile dotée d’applications (AMIKEO, Auticiel®) et un groupe de comparaison de 11 enfants (âge moyen : 9 ans 2 mois) utilisent des supports classiques recommandés par les evidence-based practices (EBP). Leurs compétences sont évaluées au début de l’étude et au terme d’une année de travail à partir de leurs scores aux items de la VINELAND-II. Résultats. Ces scores augmentent significativement chez les enfants du groupe cible, mais pas chez ceux du groupe de comparaison. Conclusion. Les outils numériques facilitent plus que les outils classiques les apprentissages des compétences adaptatives et sociocommunicatives des enfants avec TSA et TDI associé.
Reducing the split-attention effect of subtitles during video learning: might the use of occasional keywords be an effective solution?
Authors: Cojean Salomé , Martin Nicolas
Published: November 2021

Les vidéos pédagogiques présentent des bénéfices (e.g., animations, multi-modalité) mais également des contraintes à prendre en compte. Par exemple, en présence de sous-titres, un effet d’attention divisée peut apparaître entre l’audio, le texte écrit et les illustrations. Une solution serait de présenter des mots-clés à la place des sous-titres afin d’éviter une redondance inutile et de guider l’apprenant à sélectionner l’information pertinente. Dans cette étude, 96 participants ont appris une vidéo de 12 minutes avec ou sans sous-titres, et avec ou sans information mise en saillance (i.e., mots-clés). Les résultats n’ont montré aucun effet des sous-titres, mais les mots-clés ont un effet négatif sur la mémorisation, la compréhension et le temps d’apprentissage. Ces résultats sont discutés en termes de stratégies mises en place. Les apprenants n’auraient pas utilisé les mots-clés pour les guider dans la sélection de l’information, mais les auraient considérés comme remplaçant ce processus, surestimant ainsi leur apprentissage.
Questionnaire MiFID et participation sur les marchés actions
Authors: Broihanne Marie-Hélène , Orkut Hava
Published: November 2021

La Directive sur les marchés d’instruments financiers (MiFID) a pour objectif de protéger les investisseurs européens. Elle impose aux prestataires de services d’investissement de collecter des informations sur leurs clients via un questionnaire. Dans cet article, nous combinons les réponses au questionnaire MiFID et les données bancaires d’environ 50 000 clients d’une grande banque commerciale en France. Nous montrons que les indicateurs MiFID, c’est-à-dire la littératie financière subjective, la tolérance au risque et les attitudes face aux pertes auto-évaluées, affectent significativement la participation sur les marchés actions tout en contrôlant divers déterminants classiques, tels que les caractéristiques sociodémographiques et la richesse nette. Nos résultats sont robustes à une approche par variable instrumentale pour la littératie financière. Classification JEL  : G02, G11, G28
Parametric design analysis of elliptical shroud profile
Authors: Akour Salih Nawaf ,   Mechanical Engineering Department, School of Engineering, The University of Jordan, Mhaisen Mahmoud Azmi Abo
Published: November 2021

Parametric design analysis for Eccentric Rotated Ellipsoid (ERE) shroud profile is conducted whereas the design model is validated experimentally. A relation between shroud inlet, length and exit diameter is established, different ratios related to the wind turbine diameter are introduced, and solution for different ERE family curves that passes on the inlet, throat, and exit points is studied. The performance of the ERE shroud is studied under different wind velocities ranging from 5–10 m/s.

The method used in creating the shroud profile is by solving the ERE curve equations to generate large family of solutions. The system is modeled as axisymmetric system utilizing commercial software package. The effect of the parameters; shroud length, exit diameter, inlet diameter, turbine position with respect to the shroud throat, and wind velocity are studied. An optimum case for each shroud length, exit diameter and location of the shroud with respect to the wind turbine throat axis are achieved.

The simulation results show an increase in the average wind velocity by 1.63 times of the inlet velocity. This leads to a great improvement in the wind turbine output power by 4.3 times of bare turbine. One of the achieved optimum solutions for the shroud curves has been prototyped for experimental validation. The prototype has been manufactured using 3D printing technology which provides high accuracy in building the exact shape of shroud design curve. The results show very good agreement with the experimental results.
An accelerated differential equation system for generalized equations

Published: November 2021

An accelerated differential equation system with Yosida regularization and its numerical discretized scheme, for solving solutions to a generalized equation, are investigated. Given a maximal monotone operator \begin{document}$ T $\end{document} on a Hilbert space, this paper will study the asymptotic behavior of the solution trajectories of the differential equation

   \begin{document}$ \begin{equation} \dot{x}(t)+T_{\lambda(t)}(x(t)-\alpha(t)T_{\lambda(t)}(x(t))) = 0,\quad t\geq t_0\geq 0, \end{equation} $\end{document}

to the solution set \begin{document}$ T^{-1}(0) $\end{document} of a generalized equation \begin{document}$ 0 \in T(x) $\end{document}. With smart choices of parameters \begin{document}$ \lambda(t) $\end{document} and \begin{document}$ \alpha(t) $\end{document}, we prove the weak convergence of the trajectory to some point of \begin{document}$ T^{-1}(0) $\end{document} with \begin{document}$ \|\dot{x}(t)\|\leq {\rm O}(1/t) $\end{document} as \begin{document}$ t\rightarrow +\infty $\end{document}. Interestingly, under the upper Lipshitzian condition, strong convergence and faster convergence can be obtained. For numerical discretization of the system, the uniform convergence of the Euler approximate trajectory \begin{document}$ x^{h}(t) \rightarrow x(t) $\end{document} on interval \begin{document}$ [0,+\infty) $\end{document} is demonstrated when the step size \begin{document}$ h \rightarrow 0 $\end{document}.

Existing epileptic seizure automatic detection systems are often troubled by high-dimensional electroencephalogram (EEG) features. High-dimensional features will not only bring redundant information and noise, but also reduce the response speed of the system. In order to solve this problem, supervised locality preserving canonical correlation analysis (SLPCCA), which can effectively use both sample category information and nonlinear relationships between features, is introduced. And an epileptic signal classification method based on SLPCCA is proposed. Firstly, the power spectral density and the fluctuation index of the frequency slice wavelet transform are extracted as features from the EEG fragments. Next, SLPCCA obtains the optimal projection direction by maximizing the weight correlation between the paired samples in the class and their neighbors. And the projection combination of original features in the optimal direction is the fusion feature. The fusion features are then input into LS-SVM for training and testing. This method is verified on the Bonn dataset and the CHB-MIT dataset and gets good results. On various classification tasks of Bonn data set, the proposed method achieves an average classification accuracy of 99.16%. On the binary classification task of the inter-seizure and seizure epileptic EEG of the CHB-MIT dataset, the proposed method achieves an average accuracy of 97.18%. The experimental results show that the algorithm achieves excellent results compared with several state-of-the-art methods. In addition, the parameter sensitivity of SLPCCA and the relationship between the dimension of the fusion features and the classification results are discussed. Therefore, the stability and effectiveness of the method are further verified.

Authors: Wang Zhiqiang ,   School of Electrical Engineering, Zhengzhou University, No. 100 of Science Avenue, Zhengzhou 450001, China, Peng Jinzhu , Ding Shuai
Published: November 2021

In this paper, a novel bio-inspired trajectory planning method is proposed for robotic systems based on an improved bacteria foraging optimization algorithm (IBFOA) and an improved intrinsic Tau jerk (named Tau-J*) guidance strategy. Besides, the adaptive factor and elite-preservation strategy are employed to facilitate the IBFOA, and an improved Tau-J* with higher-order of intrinsic guidance movement is used to avoid the nonzero initial and final jerk, so as to overcome the computational burden and unsmooth trajectory problems existing in the optimization algorithm and traditional interpolation algorithm. The IBFOA is utilized to determine a small set of optimal control points, and Tau-J* is then invoked to generate smooth trajectories between the control points. Finally, the results of simulation tests demonstrate the eminent stability, optimality, and rapidity capability of the proposed bio-inspired trajectory planning method.
Axiomatic results and dynamic processes for two weighted indexes under fuzzy transferable-utility behavior
Authors: Liao Yu-Hsien
Published: November 2021

By considering the supreme-utilities and the weights simultaneously under fuzzy behavior, we propose two indexes on fuzzy transferable-utility games. In order to present the rationality for these two indexes, we define extended reductions to offer several axiomatic results and dynamics processes. Based on different consideration, we also adopt excess functions to propose alternative formulations and related dynamic processes for these two indexes respectively.
