Bayesian Correlation between Cumulative Grade Point Average and Employment
Authors: Hakgudener Serhan
Published: December 2024

Many believe a high CGPA (Cumulative Grade Point Average) correlates with better employment opportunities. This belief stems from the idea that a high CGPA reflects a student’s dedication, intelligence, and ability to perform well under academic pressure, qualities often valued by employers. However, it is also recognized that practical skills, experience, and personal attributes play crucial roles in securing a job. Is a high CGPA enough of a metric to open job opportunities? To address this question, the study analyzes the relationship between alumni's Cumulative Grade Point Average (CGPA) and employment prospects. The research was conducted at the American University of Kurdistan (AUK), and the data was obtained from the Admissions and Registration and the Office of Advancement. The goal is to understand whether academic performance, as measured by CGPA, significantly influences the employability of graduates in the architectural engineering field. Thus, the study employs a robust methodology, using Bayesian Correlation to provide substantial evidence per the guidelines requested by the New England Commission of Higher Education (NECHE). The data involves a review of academic records and survey responses to employment data from AUK's architectural engineering alumni. Findings suggest a negative anecdotal correlation between CGPA and employment, indicating that students with higher CGPAs do not necessarily secure employment in their field of study soon after graduation.

Published: December 2024

The prediction of concrete mix proportions is of the utmost importance to civil engineers to complete the design process of structures. This process is usually done through a trial-and-error process which involves simple regression techniques and is usually done to achieve a specific strength at a specific age. The incorporation of supplementary cementitious materials into concrete mixtures for environmental purposes has deemed the prediction process more complex and created a need to come up with more advanced techniques. Furthermore, the ability to predict the constituents of concrete mixtures given multiple inputs is still limited. Hence, in this work several machine learning algorithms were utilized to make a prediction regarding mix proportions of concrete mixtures based on concrete compressive strength, concrete age, and density as inputs. Random forest, decision tree, and K-neighbors regressors were used to achieve this objective. Mean squared error as well as root squared error were used to measure the accuracy of the constructed models. Random Forest algorithm obtained the highest accuracy with 98.5%.

Published: December 2024

Over the past four decades, Algeria has suffered considerable losses, due to several large earthquakes that hit its various northern parts. These destructive effects are amplified by the large volume of buildings constructed using imprecise and unfinished codes (before the appearance of the Algerian paraseismic code RPA99/03). Indeed, the majority of cities have developed in total ignorance of seismic risks. Also, these heavy losses recorded are the consequence of the use of poor materials as well as poor control of implementation. Furthermore, reducing human and economic losses during a disaster requires raising awareness among the population at risk. In this context, a study on the seismic vulnerability of constructions built before 2003 is carried out in our laboratory. Knowing that the “IV” vulnerability index level to be considered for a structure threatened by an earthquake is a combination of several parameters. This document proposes an approach to quantify the “IV” index level of column-beam buildings, based on the design of experiments method (DEM). The DEM is a correlation established between this “IV” index level and certain parameters considered sources of danger by several researchers. Two types of factors are distinguished: those designated as internal to the construction, such as: the age “Ag”, the symmetry in plane “Sy”, the regularity in elevation “Re”, the quality of the bracing “Qc”, the quality of the resistant system “Qr”, the state of conservation “Ec”, the secondary elements “Es”, the infrastructure “If” and the redundancy of the rows “Rf” and those designated as external, such as: collision “And” and the ground condition “So”. The resulting formula from this correlation allows managers to classify vulnerable buildings with a better approximation.

Published: December 2024

Tungsten Inert Gas (TIG) is widely utilized across various industries. The understanding of tungsten electrode behavior, key component in this process, is vital for optimizing processes and enhancing weld quality. The shape of the electrode tip, influenced by its operational characteristics, significantly impacts the behavior of the electric arc and, consequently, the quality of the welded assembly. This study aims to analyze the influence of current intensity on the thermal and electrical characteristics of the cathode tip during TIG welding, using numerical simulations conducted with Comsol software. The analyses are carried out by applying Direct Current (DC) welding on an aluminum alloy sheet. The results show a similar evolution in the operational characteristics of the electrode as its tip angle varies. In contrast, the current intensity affects only the temperature, which increases with a higher tip angle, while the current density depends solely on the geometry of the electrode tip. The appropriate selection of welding parameters is imperative to preserve the electrode shape and ensure an efficient welding process.

Authors: MANASRAH Ahmad , JARADAT Yousef , MASOUD Mohammad , JARADAT Mohammad
Published: December 2024

Bifacial photovoltaic systems (bPVs) have become increasingly popular in the past decade due to their ability to generate electricity from both sides of the module, resulting in improved efficiency through the utilization of scattered and reflected light. Typically, while bPVs tend to be more expensive than traditional monofacial photovoltaic panels, this is offset by their higher energy output on less land space. An economic analysis is conducted in this study to swap out a 2.4 MW single-sided solar panel system with bifacial ones on the rooftops of a university campus in Jordan. The additional space generated will be used to enhance the system's capability. The findings indicated that the new double-sided system could reduce the required area by over 27% if its capacity matched the current system. The findings indicated that expanding the area significantly augmented the current capacity by 47%. The return on investment (ROI) for the replacement procedure is 5.43% with a payback period of 8.2 years over a lifespan of 20 years.

Published: December 2024

In this project work, the impact of porosity on the nonlinear thermal buckling response of power law functionally graded beam with various boundary conditions is investigated; the derivation of equations is based on the Euler–Bernoulli beam theory where the distribution of material properties is imitated polynomial function. Using the nonlinear strain–displacement relations, equilibrium equations and stability equations of beam are derived. The beam is assumed under thermal loading, namely: Nonlinear temperature distribution through the thickness. Various types of boundary conditions are assumed for the beam with combination of roller, clamped and simply-supported edges equations for these types of structures. The effects of the porosity parameter, slenderness ratio and power law index on the thermal buckling of P-FG beam are discussed.

Published: December 2024

This work focuses on the valorization and recycling of waste materials of brick aggregates (BA) and demolition concrete aggregates (DCA) for the formulation and mechanical characterization as well as the study of the durability of concrete.Five (05) concrete formulations; a control concrete based on natural aggregates and four concrete formulations based on recycled aggregates by volume substitution of natural aggregates with rates of 25% and 50% brick waste and 50%, 75% demolition concrete waste, were studies in the fresh state to estimate the workability and the density and in the hardened state to estimate the mechanical properties and the durability of concretes: Compressive and flexural strengths, impermeability to water and the diffusion of chloride ions.The results of this experimental study show that the increase in the rate of demolition or brick aggregates wastes in substitution of natural aggregates causes a decrease in the mechanical characteristics and the durability of the concrete. Nevertheless, concrete mixes containing 50% of recycled aggregates have good mechanical resistance and good durability which are close to that of concrete based on natural aggregates. Therefore, the results obtained suggest a possible use of brick and demolition concrete wastes, as aggregates in the formulation of structural concretes.

Authors: KUSYUMOV Alexander , KUSYUMOV Sergey
Published: December 2024

One of the objectives in the study of turbulent flows is to determine the spectral features of flow parameters. Typically, the longitudinal and transverse components of the velocity vector are parameters for which spectral analysis is carried out. In the present study, the spectrum of pulsations of a turbulent velocity sampled in the spatial domain is considered. An application with the Reynolds number of 3900 is being examined for a turbulent flow past a 3D cylindrical surface. Numerical simulation is performed using ANSYS Fluent commercial code and based on the Navier-Stokes equations. The spatial signal is sampled on the centerline downstream of the flow. The energy of the transversal component of the velocity vector is analyzed using Fourier transforms of a signal sampled in the spatial domain. Two approaches are considered to study the spectral properties of the signal. The traditional Energy Signal Density (ESD) estimation is analyzed using Parseval’s theorem. The alternative Energy Signal Spectra (ESS) estimation approach is based on the local signal energy definition. The energy spectra performances are compared to the “–5/3” law of A.N. Kolmogorov.

Analysis of Delamination in Statically Indeterminate Steric Frames Subjected to Fixed Support Rotation
Authors: RIZOV Victor
Published: December 2024

The paper is devoted to the problem of delamination in multilayered steric frames. The attention is focussed on statically indeterminate load-bearing frame structures that are under fixed support rotation. External mechanical loading is not applied on the frames under consideration. Only the stresses and strains induced by the fixed support rotation causes delamination. The layers of the frame are made of structural materials that continuously inhomogeneous in longitudinal direction. Thus, the elastic properties of the layers vary smoothly along the length of the frame portions. Due to steric geometry of the frame, the fixed support rotation generates torsion and bending in the frame portions. Therefore, in this paper we analyze delamination behaviour under combined action of bending and torsion moments. First, the mechanical behaviour of the frame portions is studied by using the equations of equilibrium. Then the strain energy release rate (SERR) is determined by analyzing the frame compliance.

Published: December 2024

Visible Light Communication (VLC) presents a promising technology for future wireless communication systems, offering a high-speed and secure alternative to traditional radio frequency (RF) based wireless systems. To enhance VLC performance, the Orthogonal Frequency Division Multiplexing (OFDM) technique has been employed. OFDM's high spectral efficiency and robustness to multipath interference make it well-suited for mitigating inter-symbol interference (ISI) and maximizing spectral efficiency. This study explores the OFDM-VLC system under OptiSystem software, utilizing a high-efficiency Perovskite-based Light-Emitting Diode (LED). Specifically, the investigation emphasizes the SrLa2Al2O7:Er3+ LED, which exhibits high luminescence efficiency with a Quantum Efficiency (QE) of approximately 68.33%. The impact of the number of OFDM subcarriers and the SrLa2Al2O7:Er3+ LED's characteristics on system performance are thoroughly analyzed over various channel ranges and bit rates. To evaluate the system's efficacy, the performance of the proposed OFDM-VLC system was rigorously assessed using rigorous performance metrics, including Bit-Error Rate (BER) and constellation diagrams. The findings unequivocally demonstrate the substantial enhancement in communication reliability and efficiency achieved by the proposed OFDM-VLC system based on SrLa2Al2O7:Er3+ LED.

Foot health plays a critical role in maintaining overall health and functions. Foot fitness is dependent upon many factors. Various problems limit the foot's functionality and affect the quality of life. Posture, gait, mobility, and balance are directly related to podiatric health. The study aimed to determine foot health and quality of life in individuals with foot dysfunctions and establish its relationship with quality of life. A cross-sectional survey was conducted among the general population of the twin cities of Pakistan (Islamabad & Rawalpindi). A self-structured online questionnaire was distributed among 323 individuals aged 25-60 years suffering from different foot problems. The study showed that 259 (80.19%) of the participants were females, and 64 (19.81%) were males. Teachers, nurses, beauticians, and housewives reported moderate pain levels on numeric pain rating scales, likely associated with long standing hours and the use of flat and tight shoes. This impacted their ability to perform daily tasks, moderate to vigorous activities, and limited ability to walk. This study concluded that the most commonly reported issues were heel pain, ankle pain, and metatarsalgia. Moreover, the commonly affected foot regions were the hind foot and toes. Diet and social life remained mostly unaffected in individuals with heel pain and edema as these conditions were very common among the selected population, and they adapted their lifestyles accordingly. In conclusion, health and quality of life were negatively impacted in individuals with metatarsalgia, flat foot, and ankle sprain.

The article examines the current problems of spreading corruption in Ukraine. It has been established that corruption is a negative socio-economic phenomenon that restrains the state's economic development, reduces trust in the authorities and complicates the fight against Russia's military aggression. The coming years will be indicative for Ukraine's international partners in the context of assessing the effectiveness of national anti-corruption policy, and the degree of implementation of planned anti-corruption reforms, which will indicate the level of integration of European values into society and Ukraine's readiness to become a full member of the EU. The perception of the main corruption problems by the public and business was analyzed, and it was established that the general attitude of Ukraine towards corruption is shifting towards intolerance of this negative phenomenon. Based on the analysis of the dynamics of detected financial violations by the State Audit Service of Ukraine in the region for 2019-2023, the TOP-3 conditional regions that are prone to violations, including corruption, have been determined. A trend analysis of the volume of financial violations was carried out, which proved the average annual changes in the volume of the number of accrued violations for the years 2019-2023 and allowed us to make a forecast for 2026. The results of the foresight analysis show that the volume of financial violations in 2026 may reach the level of UAH 68,956.5 thousand. Accounting criminal and administrative violations by types of corruption during 2019-2023 were studied. The structural analysis of violations for 2019-2022 shows that the top three corruption methods included: an offer, a promise or the granting of an undue advantage to an official (21,9%); failure to take appropriate measures to combat corruption crimes (15,7%); declaring false information (12,8%). The analysis confirmed the significance of anti-corruption audits of companies and the formation of an anti-corruption independent audit system.

Інноваційна діяльність підприємств виступає як фундамент для зміцнення їхньої позиції в галузі, забезпечуючи стійкий доступ до передових технологій. Аналіз взаємозв'язків між доступом до кредитування та інноваційною діяльністю дозволяє не лише оцінити ефективність інвестиційних рішень підприємств, а й визначити бар'єри, що заважають їхньому прогресові. Саме це обумовлює актуальність обраної теми дослідження. Метою цього дослідження є визначити вплив кредитування на інноваційність підприємств легкої промисловості, що є суттєвим для розуміння механізмів, які сприяють розвиткові галузі. Для встановлення причиново-наслідкових зв’язків використано тест Ґрейнджера. Для перевірки моделі проведено тест Дікі-Фулера. Оцінку впливу та аналіз здійснено за допомогою кореляційно-регресійного аналізу. Результати дослідження вказують на те, що відсутній причиново-наслідковий зв’язок між кредитуванням і зростанням кількості інноваційних підприємств легкої промисловості. Згідно з даними регресійного аналізу, інвестиції в інноваційні підприємства в Швеції демонструють значний позитивний ефект, адже збільшення фінансування на 1 мільйон доларів веде до 11% зростання кількості таких компаній. У США підвищення кредитування на ту саму суму стимулює лише 4% зростання інноваційних підприємств легкої промисловості. Великобританія зафіксувала подібний показник на рівні 2%, водночас у Сінгапурі він сягає 6%. Ці відмінності свідчать про варіативність ефективності інвестицій у різних країнах. Отримані результати можуть значно сприяти поглибленню досліджень застосування кредитування для впровадження інновацій на підприємствах легкої промисловості. Перспективним напрямом подальшого аналізу є вивчення впливу кредитних механізмів на інноваційний розвиток галузі легкової промисловості в країнах, що розвиваються. Це дослідження має потенціал для виявлення ключових факторів, які сприяють успішному впровадженню нововведень у цій царині.

Published: December 2024

In recent years, the global transportation sector has witnessed a shift towards electric vehicles powered by renewable energy sources. Experts predict an increasing role for electric vehicles in leading economies due to the depletion of fossil fuels and the harmful emissions from internal combustion engines. The rise in energy prices and stringent environmental regulations further drive this transition. The main goal of the research work is to study the relationship between the production of electric cars, government subsidies, oil prices, GDP per capita and R&D investments. Correlation analysis was chosen as the main method, but a graphical method was also used for visualization. There is a strong positive correlation between the production of Tesla electric cars and the price of oil, indicating that higher oil prices make Tesla electric cars a more attractive, cost-effective, and environmentally friendly alternative to gasoline and diesel cars. Based on the conducted analyses, it can be emphasized that the global transition to the production and use of electric vehicles is a critically necessary response to climate change, the reduction of fossil fuel reserves, and the growing need for sustainable development. This transition helps increase energy efficiency, reduce dependence on oil, and improve air quality in cities by reducing emissions of harmful substances.

Published: December 2024

The widespread adoption of smartphones raised worries about addictive behaviours, especially smartphone addiction and phubbing. Contrary to prior research, the study aimed to investigate, phubbing as predictor of smartphone addiction, and determining the mediating role of cognitive flexibility in the association between phubbing and smartphone addiction. A cross-sectional survey was conducted among 255 participants (42% males, 58% females), aged 18 to 30 years. Data were collected using the Generic Scale of Phubbing (GSP) to measure phubbing, the Smartphone Addiction Scale-Short Version (SAS-SV) to assess smartphone addiction, and A New Measure of Cognitive Flexibility to evaluate cognitive flexibility. The findings showed a negative correlation between phubbing and cognitive flexibility and a positive correlation between higher levels of phubbing and increased smartphone addiction. The association between phubbing and an addiction to smartphones is partially mediated by cognitive flexibility, according to mediation analysis. Furthermore, there were no gender differences in cognitive flexibility or smartphone addiction, but there were notable gender differences in phubbing action, with men scoring higher than women. This study emphasizes the mediation impact of cognitive flexibility and the crucial importance of phubbing as predictor of smartphone addiction. Enhancing cognitive flexibility through interventions could be a useful strategy for reducing smartphone addiction and fostering young people's digital well-being.
Comparison of cyclic fatigue resistance of different rotational and reciprocal file systems

Aim: The purpose of this study is to compare the cyclic fatigue resistance of the TruNatomy and ProTaper Next file systems, which work rotational movements, and Reciproc and WaveOne Gold file systems, which work reciprocal movements.
Methods: ProTaper Next X2 (25/.06), WaveOne Gold Primary (25/.07), Reciproc R25 (25/.08), and TruNatomy Prime (26/.04) files were used in the cyclic fatigue test. Four groups, 15 files from each group and a total of 60 files, were rotated in an artificial canal made of curved stainless steel with a curvature angle of 60 degrees, an inner diameter of 1.5 mm, and a radius of curvature of 3 mm. The breaking times of the files were determined with a digital stopwatch, and this value was converted into the number of cycles until breaking. Compliance with normal distribution was examined with the Shapiro‒Wilk test. The number of cycles until fracture for the respective files, which did not follow a normal distribution, were compared using the Kruskal‒Wallis test and multiple comparisons were made with the Dunn test. The analysis results were presented as mean ± standard deviation and median (minimum-maximum). The significance level was taken as p<0.050.
Results: While the TruNatomy system had the highest number of cycles until fracture occurred, no statistically significant difference was found between the Reciproc and WaveOne Gold systems. The ProTaper Next system showed the lowest cyclic fatigue resistance.
Conclusion: Within the limitations of the present in vitro study, TruNatomy, which makes rotational motion, showed the best cyclic fatigue resistance. The ProTaper Next system was the file with the lowest cyclic fatigue resistance. Obtaining similar results for files produced in different shapes and with different movement kinematics allowed us to conclude that cyclic fatigue is multifactorial.

Os animais não humanos no âmbito do Direito das Famílias e do Superior Tribunal de Justiça: a legislação portuguesa como bússola
Authors: Rubião André , Lopes Fernanda Toffanetto Gomes
Published: December 2024

A temática proposta por este estudo encontra-se no assinalado questionamento: a real proteção dos animais não humanos está na alteração da sua natureza jurídica? O método utilizado foi o hipotético-dedutivo. Primeiramente buscou-se entender a relação de afetividade entre animais não humanos e seres humanos dentro da perspectiva do Direito das Famílias. Após, buscou-se analisar especificamente o que o Superior Tribunal de Justiça já discutiu acerca da temática. Posteriormente buscou-se analisar a natureza jurídica dos animais não humanos perante um viés doutrinário e demonstrar que a legislação portuguesa seria um bom exemplo a ser seguido pelo ordenamento jurídico brasileiro. Por fim, concluiu-se que uma verdadeira proteção dos animais não humanos não estaria no seu status normativo, mas sim na elaboração de legislações específicas e de um estatuto próprio.

Доклад посвящен статистическому анализу аварийности и надежности и оценке на этой основе риска возникновения аварийных ситуаций при бурении скважин и спуске обсадных колонн.
В результате статистического анализа и нечёткого кластер-анализа по двум признакам, определяющим последствие аварии, установлено пять классов по степени опасности аварии, предложен обобщённый показатель последствий аварий и получена зависимость частоты аварий от данного показателя. Показано, что с увеличением обобщённого показателя последствий аварий частота аварий снижается, подчиняясь гиперболическому закону.
Установлено, что распределение величин недоспуска колонн подчиняется закону Вейбулла. Приводится методика оценки риска возникновения случаев недоспуска обсадных колонн. При этом предложен показатель риска, численно равный произведению частоты (вероятности) возникновения аварии на обобщённую характеристику последствий, с показателем степени, равным степени гиперболической зависимости, описывающей кривую риска.
Ключевые слова: аварийность, надежность, оценки риска, вероятности.
