The selection process of a coaching model should be an initial consideration before conducting training activities. However, the limited availability of coaching models hinders the delivery of quality training programs. Therefore, it is necessary to have options for coaching models. This research aims to develop a goal, actual, alternative, plan, action, monitoring, and reflection based on blended learning (GAARANTUNG) a coaching model rooted in goal, reality, option, will (GROW) with the addition of action, monitoring, and reflection elements based on blended learning. The development of this coaching model is conducted by adopting the analysis, design, development, implementation, and evaluation (ADDIE) research and development concept, which involves three main steps: analysis, design, and development. The results of this research include the availability of a coaching model that meets the needs, including the incorporation of technological elements within GAARANTUNG. The GAARANTUNG coaching model is the improved version of the GROW coaching model, which only focuses on action planning, and the goal, reality, option, will-monitoring, evaluation (GROW-ME) coaching model, which lacks a description of coaching during action and does not include digital technology elements. The refinement of the syntax in GROW and GROW-ME to form GAARANTUNG is a crucial step in providing a coaching model that aligns with the needs and facilitates the implementation of training programs, specifically targeting the main needs of participants, including teachers and school principals.

Published: July 2024

Sudoku is a puzzle that has a unique solution. No matter how many methods are used, the result will always be the same. The player thought that the number of givens or clues, the initial value on the Sudoku puzzles, would significantly determine the difficulty level, which is not necessarily correct. This research uses two search algorithms, breadth-first search (BFS) and depth-first search (DFS), to solve a set of Sudoku puzzles based on the number of givens. The Sudoku puzzles are chosen based on the number of givens between 32 and 35. In cases where Sudoku puzzles are considered medium or intermediate difficulty, the solutions generated by both algorithms will be compared with the human-solving approach. The research aims to determine whether humans tend to solve Sudoku puzzles with solutions resembling those generated by BFS or DFS. Furthermore, if all three approaches-human, BFS, DFS-yield comparable solutions, the Sudoku puzzle has only one unique solution.

Published: July 2024

Proficiency in solving mathematical problems is essential for preservice elementary teachers, as they will teach foundational math concepts and foster problem-solving abilities among young learners. However, many studies found low problem-solving performance among preservice teachers. In line with this, the present study examined how problem-solving disposition relates to the performance of preservice elementary teachers, conducted at a selected higher education institution in Nueva Ecija, Philippines, with 134 participants. The study utilized a mathematical problem-solving disposition and beliefs scale questionnaire and a problem-solving test scored using the identify, define, explore, act, and look (IDEAL) model. Results indicated an average problem-solving disposition and high problem-solving performance among preservice teachers. Linear regression analysis showed that overall problem-solving disposition is a predictor of performance. Further, stepwise regression analysis revealed that two disposition parameters, mathematical mindset (β = 2.413, p 0.01) and community of practice (β = 1.866, p 0.01), significantly predicted problem-solving performance. These findings show the significance of developing a problem-solving disposition, mindset, and learning communities to improve future teachers’ problem-solving ability by providing more learning opportunities, interdisciplinary problems, and social engagements.

Published: July 2024

This paper aims to analyze the impact of body dissatisfaction on communication competencies among engineering college students and to put forth remedial strategies. As body dissatisfaction is still a grey area in research-related communication competencies, the researchers have focused on this arena. Sixty-one heterogeneous participants (male=30 and female=31) from one of the private engineering colleges in Tamil Nadu, India, participated during the summer semester. The judgment under the non-probability sampling technique was used. Moreover, rubrics were developed with four parameters: color complex, consciousness over their physique, shame and guilt, self-blaming, and lamentation. In addition, class observation techniques were used based on the aforementioned rubrics; the students accessed their classroom presentation using an evaluation sheet derived from the rubrics. The result revealed that around 70% of the participants suffered from body dissatisfaction, while the degree ranges from minimum to maximum levels. This hampers their effective communication and self-expression. With a holistic approach that combines mental health support, awareness-building workshops, peer mentorship, and communication skills training, the participants are mitigated by the impact of body dissatisfaction on communication within the student cohort.

Combined sensitivity analysis is applied for sorting the candidate nodes for DG placement and reducing the search space. Multi-criteria decision-making among TEE factors are addressed using a scientific approach named Analytic Hierarchy process (AHP) approach. The impact of prioritized solutions is analyzed in terms of three scenarios formed using AHP in the form of TEE criterion. The developed formulation is tested on IEEE 33-bus bus radial distribution system and is solved using hybrid optimization approach (hybrid GA-PSO) and AHP based scenarios performed better than base case scenario (non-prioritized scenario).

Incorporating photovoltaic (PV) systems to grids have developed into an obvious alternative for many countries, those results in harmonics issues for the utility operators. Harmonics arises due to extensive utilization of power-electronic components during incorporation of PV to grid. Harmonic deformation has traditionally been taken care of by the relevance of passive filter. Active filters have come up as an alternative choice over passive ones for reduction of harmonic due to existence of several advantages in comparison to previous filter. The application of controllers is the most significant aspect of using an active filter. Various investigations are beneath development to progress performance of the filters. Control of capacitor voltage is among the major regulation requirement for the filter. Here, regulation of voltage is carried on by fuzzy-controller. The article represents compensation of harmonic currents of a grid integrated PV-system by application of fuzzy-controller placed active filter. One of the important control requirements of filter is the regulation of DC link up capacitor voltage. Here the voltage supervision of capacitor is being done using PI controller. The paper shows current harmonics compensation of PV grid connected system using PI controller based active filter. Simulating results are revealed that shows the harmonics are contained inside IEEE limits.

The low operating and maintenance expenses of photovoltaic (PV) power generation make it a popular choice for rural power generation systems. Solar radiation, temperature, and load impedance are the major factors influencing the final output of solar PV. Consequently, the solar PV system experiences oscillations in its operation. These oscillations in the operating point pose a difficulty in transferring maximum power from the source to the load in an efficient way. A method called as “maximum power point tracking” is used to address this problem. This technique eliminates oscillations ensure that stability of operating point at the maximum power point. PV has several maximum power points (MPP) under partial shade situations, which is characterized by its non-linear features. As a result, it is challenging to find actual MPP. While tracking and collecting the maximum power from PV, the cuckoo search optimization (CSO) technique developed by biological intelligence is used in this article. The cuckoo search (CS) has several advantages, including a short tuning process that is efficient as well as fast convergence. The step-up converter steps up the voltage. In order to steady the converter, the counter variable is employed to provide delay. Resistive load is present.

This study presents a novel topology for a high-gain Cuk converter without isolation, leveraging switched-inductor (SL) and switched-capacitor (SC) networks tailored for renewable energy sources. Unlike traditional Cuk converters that perform negative-to-positive boost DC-DC voltage conversion, this innovative design offers a significantly enhanced voltage-boosting capacity. They evolve from the conventional Cuk converter by integrating an SL instead of the singular inductor and substituting the energy-transferring capacitor with an SC. The standout benefits of the modified Cuk converters include a remarkable voltage conversion ratio and minimized voltage stress on the primary switch, allowing a low-voltage-rated switch for greater efficiency. Comparatively, the proposed designs surpass the classical Cuk and a few modified Cuk converters in voltage gain and reduced switch voltage stress. The converter also avoids the need for transformers or coupled inductors, resulting in minimized volume, loss, and expense. The converters' operation in continuous conduction mode is rigorously analyzed in this study. After deriving all the relevant equations, they are validated against outcomes. The proposed Cuk converter topology was simulated using the MATLAB/Simulink tool, and the findings are deliberated. The performance of the proposed converter is compared with the other converters, and the proposed converter's superiority is proved through the obtained results.
Multiport bidirectional converter for solar fed hybrid electric vehicle using switched reluctance motor drive

For use in solar-assisted hybrid electric vehicle applications, a multiport bidirectional switched reluctance motor (SRM) drive is suggested in this research. Since the photovoltaic (PV) system's output voltage is low and insufficient to reach the necessary voltage level, a high gain KY converter is used to increase the PV output. The 8/6 SRM receives the steady converter output via the (n+1) diode (n+1) converter architecture with the help of the proportional integral (PI) controller. A PI controller regulates the SRM's speed. A bidirectional battery converter connects the battery, which is attached to the DC bus, to the extra power from the PV. A PI controller manages the bidirectional battery converter's operations. When necessary, the battery transfers the excess energy from the PV to the SRM drive. The outcomes demonstrate that, when examined using MATLAB simulation, the recommended methodology functions well.
