Digital pseudo-random modulation: a key to EMI reduction in EVS boost converters
Authors: M'barki Zakaria , Salih Ali Ait , Mejdoub Youssef , Rhazi Kaoutar Senhaji
Published: July 2024

Pseudo-random position pulse modulation (RPPM) technique can be implemented either analogically using pseudo-random binary sequences (PRBS) to generate a pulse-width modulation (PWM) control signal or digitally through an Arduino Uno board. It plays a critical role in mitigating conducted electromagnetic emissions (EMI) in boost converters dedicated to electric vehicle systems (EVS) applications. The digital implementation offers a significant advantage by enabling a substantial widening of the frequency spectrum of the control signal. This expanded spectral range results in a noticeable reduction in emitted electromagnetic interference (EMI), making the digital method the preferred choice. The increased spectral bandwidth effectively mitigates EMI, which is particularly advantageous for EMI-sensitive EVS systems. In conclusion, the digital pseudo-random modulation approach, facilitated by Arduino Uno, proves to be more effective in reducing EMI in EVS boost converters. Its capability to broaden the control signal's frequency spectrum leads to a favorable reduction in emitted EMI, ultimately enhancing electromagnetic compatibility and overall system performance.

Authors: Annapandi P. , Lakshmi D. , Santhoshi B. Kavya , Annapoorani P.
Published: July 2024

The wide deployment of grid-connected renewable energy system has piqued immense attention recently, in response to rising electricity consumption, diminishing fossil fuel reserves in addition to the need for reducing carbon emissions. Among the available sources of renewable energy, photovoltaic (PV) power generation is the most promising technology with enormous potential and easy access. This paper presents an optimum control technique for grid connected PV systems. The improved single ended primary inductor converter (SEPIC) controls and regulates PV output power to the optimum voltage level. The working of the improved SEPIC is controlled by a proportional-integral (PI) controller optimized by meta-heuristic technique of lion swarm optimization (LSO). The constant output from the converter is then supplied to the power grid through a single-phase voltage source inverter (1𝜙 VSI). The effectiveness of the proposed control strategy is ascertained using hardware validation with DSPIC3050FPGA controller and MATLAB simulation generating a reduced total harmonic distortion (THD) of 3.9% and 2.9%, respectively. Furthermore, the proposed system generates an enhanced voltage gain of 1:10 and an efficiency of 96%.
Load shedding in islanded microgrid using fuzzy linear programming
Authors: Maroko Josiah Teyah , Murage David K. , Hinga Peterson Kinyua
Published: July 2024

The primary goal of any power microgrid is to provide consumers with reliable power. This becomes a challenge with the continued growth of population which necessitates a corresponding rise in power supply. However, this continued rise in power consumption with a limited power supply can result in voltage collapse and ultimately power outage. In times of severe disturbances in an islanded microgrid (IMG), load-shedding (LS) helps to avert the occurrence of a blackout. The IMG is usually supplied by distributed generations (DGs) which have low inertia or inertia less. Thus, when in islanded mode power imbalance is usually solved by performing optimal LS to prevent the system from plunging into a total blackout. This paper presents a hybrid method which is a combination of fuzzy and linear programming algorithm for optimal LS in IMG. The developed method is centered on power generation, load demand and power prioritization. The fuzzy linear programming (FLP) algorithm is tested on the IEEE 14 bus system. The simulation results show that the proposed algorithm is effective in shedding optimal loads to ensure equilibrium is restored and frequency is within set values of 50 Hz.

Published: July 2024

Electric vehicle (EV) performance is greatly influenced by the motor drive system's stability, efficiency, and safety. With the increased usage of electric vehicles, fault detection and diagnostics (FDD) of the motor drive system has become an important topic of research. In recent years, there has been a lot of interest in artificial intelligence (AI) approaches employed in FDD. This paper provides an overview of the application of AI in defect detection for electric vehicles. The FDD method is divided into two steps: feature extraction and fault classification. Feature extraction involves identifying relevant parameters or characteristics from the EV's sensors and signals, enabling the AI system to capture meaningful patterns. Subsequently, fault classification employs AI algorithms to categorize and identify specific faults based on the extracted features, facilitating efficient diagnosis and maintenance of EVs. In the realm of EVs, the combination of AI techniques and FDD has the potential to improve performance, reliability, and safety while enabling proactive maintenance and reducing downtime. Using machine learning and deep learning, we can detect the fault in the system before it starts damaging our EV.

Authors: Vijayan Abhilash T. , Dev Jothish V. , Henry Healsa
Published: July 2024

The demand for electric vehicles (EVs) is rising due to the environmental impact of zero emission, high efficiency, and a deterioration in the levels of conventional fuels. Initial expense, the range, the time for charging and the availability of charging stations narrows their popularity. Alternately, smart approaches like vehicle-to-home (V2H), vehicle-to-vehicle (V2V), and vehicle-to-grid (V2G) charging schemes can modify this situation and shape the grid-side load curves. Vehicles in need can utilize V2V, where the transfer of charge between electric vehicles ensures the transit up to the nearby charging stations. There are wired and wireless modes in V2V topology. When equipped with the required switchgear, wireless power transfer (WPT) between electric vehicles offers great possibilities in charge sharing. A wireless charging system gives EV owner’s freedom of easy charging without waiting in a queue. This paper compares the performance and utilities of wired scheme and wireless scheme for power transfer between vehicles. Both the strategies check the state of charge (SoC) of the batteries and facilitate the power transfer. Simulations in MATLAB/Simulink and experimental results validate the proposed schemes.

Authors: Sahu Gokulananda , Panigrahi Rakhee , Patjoshi Rajesh Kumar , Kolluru Venkata Ratnam
Published: July 2024

This paper represents a least mean square (LMS) built Adaline current estimator in conjunction with model predictive control (MPC) approach (Adaline-MPC) employed for distribution-static-compensator (DSTATCOM) to enrich power quality within power distribution network. The real fundamental frequency components of load currents are estimated via LMS-built Adaline adopting instantaneous weight computation and reference currents are further formed by means of multiplying these weights with unit vector templates. A proportional-integral (PI) controller is engaged in support of continual maintenance of DC-capacitor voltage. Moreover, the switching signals of voltage source converter (VSC) are created via applying MPC wherein source currents should track the reference currents, which is derived from Adaline current estimator. Both MATLAB based simulation and Opal-RT based real-time experimental outcomes are demonstrated and the effectiveness of the proposed Adaline-MPC based DSTATCOM towards power quality improvement has been verified.
New formulas generalized to the evaluations of solar irradiations captured on horizontal surfaces and optimal inclinations
Authors: Wadawa Boaz , Effa Joseph Yves
Published: July 2024

This work offers two significant contributions. The first concerns the proposal of a new formula for evaluating solar radiation on a horizontal plane in the sense of Joseph Fourrier's thermal equation. From which we deduce the characterization of solar radiation under overcast and almost overcast conditions. The second approach is dedicated to the calculation of solar irradiation captured on a fixed inclined surface. This consists of adding the expression of solar radiation coming from the horizontal plane with the overall balance of losses along the path of solar radiation. It appears that, contrary to the results of the models resulting from the Angstrom Prescott formula, the coefficients R= 0.9972, R2= 0.9952, and MAPE= 0.061 for the Garoua data and R= 0.8849, R2= 0.9407, and MAPE= 0.05, for the El Jadida data show that the results of the first proposed formula are well correlated with the measured values. Furthermore, using the optimal tilt angles, the second formula we proposed presents well-correlated results, such that: R= 0.9997, R2= 0.9978, and MAE= 4.1470 for Garoua data and R= 0.9994, R2= 0.9959, and MAE= 7.7742 for El Jadida data.

Authors: Anoune Kamal , Maliki Anas El , Belkasmi Merouan
Published: July 2024

This paper delves into the critical aspect of managing energy consumption in drone operations to achieve the utmost range and ensure accurate state of charge (SoC) estimation. Effective energy management is pivotal in determining the operational range of drones, allowing for longer distances and heavier payloads. The integration of precise energy estimation algorithms into operational planning extends the range of drones, facilitating swift, environmentally-conscious missions for sustainable and efficient logistics solutions. The paper introduces a mathematical model to understand energy consumption and battery behavior in drones, utilizing the hybrid pulse power characterization test and recursive least square with forgetting factor for parameter identification. To overcome the limitations of linear filters, the paper employs the accurate extended Kalman filter (EKF) in the nonlinear filter section. The EKF significantly enhances the battery management system by furnishing precise SoC data. The study evaluates two SoC estimation techniques: SoC-AH (ampere-hours) and SoC_EKF, using root mean square error for comparison. The SoC_EKF technique demonstrates higher accuracy, boasting a lower errors value of 0.78%, thus making it superior for precise drone battery SoC estimation. These findings contribute to the improved performance, reliability, and overall safety of drones.
High speed BLDC motor for grid tied PV based EV system using hybrid PSO-spotted hyena optimized PI controller
Authors: Prakash S. , Boopathy K.
Published: July 2024

The rapid adoption of electric vehicle (EV) motors has recently raised numerous issues including high expensive, complex maintenance, and resonance problems. Some of the most effective and most thoroughly investigated EV motors are 3ф induction motors and DC motors. Brushless DC (BLDC) motors for EVs are a more advanced version of the solution used in developing nations. Rising time, steady state, transient, overshoot, settling time and other characteristics of the EV based BLDC motor are difficult to control. A loss of control leads to system instability and reduces the components' lifespan. Thereby, in this work, a grid incorporated PV fed EV based BLDC motor is proposed using DC-DC converter along with hybrid optimized PI controller. An innovative high gain Luo converter has been developed with the goal to deal with the fluctuating behavior of PV systems and it provides the impressive advantages of a high conversion range, reduced voltage stress and outstanding efficiency. To considerably improve the performance of the suggested converter, the reliable hybrid particle swarm-spotted hyena optimized (PS-SHO) proportional integral (PI) controller is invented for controlling the BLDC motor's speed. The grid supplies electricity to the BLDC motor when the PV-based power source isn't accessible. The simulation used to determine the efficacy of the proposed BLDC motor system in MATLAB has confirmed that the methodology provides increased efficacy with a highest efficiency of 97.3% and a lower total harmonic distortion (THD) of 2.02%.

Published: July 2024

Purpose-distributed leadership (DL) continues to draw practitioners and researchers’ attention in the context of education leadership as early as the 21st century. While an increasing amount of literature strongly advises principals to shift toward DL practices, there is a paucity of studies that indicate the extent to which this shift is taking place in practice across Islamic secondary schools. Consequently, this study investigates the distributed of leadership practices of two Islamic secondary schools located in two different countries. Design/methodology/approach-the study uses a collective case study methodology with a mixed-method approach, and collected data from 30 school teachers and interviews six school teachers. Findings-the findings reveal that both selected Islamic secondary schools have a definite hierarchy decided by top management. The findings also indicate that when leadership roles are distributed among classroom teachers, the schools do not seem to have fixed criteria. In addition, the findings illustrate that novice teachers are slowly given responsibilities and prepared to take on leadership roles. Implications–the findings could serve as a supportive literature in practicing DL across Islamic secondary schools to reduce the workload of headteachers. The findings further link DL to the development of a professional learning community though teacher leadership. Originality/value–The significance and originality of this research arguably falls along the fact that; it is the first of its kind to empirically investigate DL practices across Islamic secondary schools in two different geographical locations.

Published: July 2024

The home learning environment (HLE) is the first environment in which children’s early learning takes place. A number of studies have provided empirical evidence that the HLE contributes to children's cognitive, socio-emotional development. This study addresses the question of the factors that can be associated with creating a positive learning environment for children at home. Pilot quantitative data was collected from 324 families through a questionnaire about the activities parents get involved with their children. The frequency of reading-related activities as well as other in-home and out-of-home learning activities was calculated. Pearson’s correlation coefficient was employed to assess the relationship between parent education levels and activities within the HLE. Questionnaire reliability was examined using Cronbach’s alpha coefficient. The results showed that the gender and educational level of parents had no influence on the frequency of their involvement in the activities or the type of activities they chose to engage. However, the parents’ educational level has an impact on their beliefs, which influence the provision of learning opportunities and the quantity and quality of parent-child interactions. Further research on parental guidance or children's academic performance could collect more information on the factors that can create a more stimulating HLE.
The impact of age on second language acquisition: a critical review
Authors: Dey Manna , Amelia Rizky , Setiawan Ananda
Published: July 2024

Age plays a significant role in second language acquisition (SLA). Research indicates that the ability to learn a second language declines with age. This study reviewed relevant studies on the impact of age on SLA in order to attain the best results as language learning methods should be tailored to the learner's age and specific needs. The results showed that younger learners are more proficient in acquiring a second language due to their brain's plasticity, which enables them to learn new information quickly. They can easily acquire the language’s pronunciation, grammar, and vocabulary through exposure and immersion. As learners age, their ability to learn a second language decreases. After adolescence, the brain becomes less plastic, and the acquisition of a second language becomes more challenging. Research also shows that language also has a positive impact on a country’s economic development, as well as improving the international relations of local entrepreneurs. However, adult learners can still learn a second language, but it may take more time and effort. Moreover, the motivation and learning strategies of language learners also play an essential role in SLA. Young learners may not have a strong motivation to learn a second language, while adult learners may have a higher motivation due to professional or personal reasons. Age is a crucial factor in SLA, but it is not the only determining factor. The learner’s motivation, learning strategies, and exposure to the second language also play a significant role in the acquisition of a second language.

Exploratory factor analysis of two most widely used materialism measurements
Authors: Saffana Kuni , Puri Valendra Granitha Shandika , Hidayat Rahmat
Published: July 2024

The material value scale (MVS) and the aspiration index (AI) are among the most prominent measurements of materialism in research. As the names indicate, the MVS measures materialism in terms of materialistic values, whereas AI measures it in the matter of aspirations. Although both instruments have been widely used in research, the question of whether materialistic values and aspirations are independent of each other remains open for examination. The answer to this question is important, considering the inconsistencies in the results of past research. Therefore, this study aims to assess the construct's similarity and dissimilarity between both self-report materialism measurements resulting from exploratory factor analysis (EFA). The study was conducted online in Indonesia in 2019, with 610 participants, Indonesian version of MVS and AI, the software of Jamovi and R Studio. The analysis consisted of the Bartlett test, Kaiser-Meyer-Olkin test, parallel analysis, minimum rank factor analysis, EFA, and reliability (Cronbach’s α). The result showed there was an intersection, but each measurement had a portion of each independence higher, hence was no sufficient evidence of similarity between both materialism constructs. The construct of materialism as value and materialism as aspiration is proposed as different. Limitations of the study and implications for research were discussed.

The objective of this research is to describe the situation of mathematical training in the early childhood education degree curricula in Spain through the analysis of the teaching guides of the subjects with mathematical content offered in the different Spanish universities. The aim is to identify the typology of subjects, the number of subjects offered, and the recommended bibliography. The methodology used is descriptive, exploratory, ex post facto, and census. For this purpose, the registry of universities, centers, and degrees was first consulted during the 2019-2020 academic year to obtain a list of all the Spanish universities that offer degrees in early childhood education and, therefore, to be able to download the corresponding teaching guides. Of the 91 universities in Spain, the early childhood education degree is taught in 66. Likewise, 101 subjects with mathematical content have been identified, although only 99 are available for analysis. Most are compulsory, have a study load of six European credit transfer system (ECTS) credits, and are taught in the third year of the degree. The recommended bibliography mainly concentrates on publications from 2001-2010 and mostly on book references.

Studies show that there is an increase of college students who prefer reading short summaries rather than long complex texts containing knowledge or theory. Thus, this study focuses on improving first-year students’ reading comprehension in Chinese courses by observing the effectiveness of teaching reading lessons in Chinese courses with the curriculum designed based on “schema theory”. The selected reading materials are extensive texts with certain knowledge or theories. For evaluation purposes, the reading test questions uses the same measure of reading proficiency levels of program for international student assessment (PISA) to assess learners’ reading comprehension, contextual reasoning, integration, and analysis abilities more accurately. By comparing the results and discrepancies of the pre- and post-assessment, the preliminary research found that the teaching practice and curriculum designed based on schema theory effectively improves learners' reading scores and instill habits to increase their tendency to reach a deeper understanding of the reading material. This finding demonstrates the effectiveness of applying schema theory to reading lessons; resulting in potential of immediate and enhanced levels of comprehension.

This study aimed to develop and evaluate an instrument for measuring 21st-century workplace skills in on-the-job training (OJT) trainees. A literature review identified 20 key skills, which became the foundation of the instrument. Its validity and reliability were tested through a pilot study involving 20 OJT supervisors, employing methods like the item-level content validity index (I-CVI) and Cronbach’s alpha. The results confirmed the instrument’s effectiveness, indicating the need for further research with larger and more diverse samples to enhance its applicability. This tool is crucial in improving OJT programs by enabling supervisors to assess and support trainees more effectively. Additionally, it serves as a resource for employers and educators in appraising potential hires and graduates, and assists institutions in refining their curricula.

Published: July 2024

The use of the learning management system (LMS) at the Malaysian Polytechnic is constantly changing according to the current situation. In addition, the relatively low acceptance of LMS in technical and vocational education training (TVET) institutions requires further study. This paper will discuss accurate construct of measurement for LMS TVET using expert consensus through Aiken's V analysis. Based on the analysis coefficient and the reliability of the content, several important constructs have been identified involving system quality, information quality, service quality, motivation, user satisfaction, intention-to-use, self-discipline, practical training, and actual use. Through quantitative analysis, every item in constructs is calculated and reviewed by an expert in order to validate the items. The minimum validity value accepted in this study is 0.75 based on Aiken's V table, thus, two items were rejected. These items were rejected due to the same meaning and being inappropriate. This study proves the instrument's content validity based on expert agreement using the Aiken agreement index. This study contributes to a suitable instrument for measuring LMS in TVET for use in subsequent studies.

Education has undergone a profound transformation, transitioning significantly from traditional face-to-face instructional approaches to a predominant reliance on online learning methodologies. This sudden change leaves questions on how to provide an affective and satisfying online leaning for students. As prior studies revealed, many factors affect the success of implementing online learning, specifically for higher education students. As a response, this quantitative study was intended to investigate the interplay of factors affecting online learning experience in higher education namely anxiety, motivation for learning, self-directed learning, online learning attitude, and computer-internet self-efficacy. An exploratory factor analysis (EFA) included 20 items of online survey distributed to undergraduate students (n=329) from several faculties at one Indonesian university to explore this issue. This study used the partial least squares structural equation modeling (PLS-SEM) application to explore the interplay among six constructs. The results showed that all six constructs namely anxiety, motivation for learning, self-directed learning, online learning attitude, computer-internet self-efficacy, and online learning experience were positively associated. It meant that those factors were statistically proven to affect students’ online learning experiences. Educators could use these results as a consideration in implementing online learning more effectively. Further implications of pedagogical practice and further research are discussed.
