Design Optimization of a Grid-Tied Hybrid System for a Department at a University with a Dispatch Strategy-Based Assessment

In this research project, the optimal design and design evaluation of a hybrid microgrid based on solar photovoltaics, wind turbines, batteries, and diesel generators were performed. The conventional grid-tied mode was used in addition to dispatch strategy-based control. The study’s test location was the loads in the Electrical, Electronic and Communication Engineering (EECE) department at Pabna University of Science and Technology (PUST), Pabna, Bangladesh. DIgSILENT PowerFactory was employed to determine the power system-based behaviors (electrical power, current, voltage, and frequency) of the proposed hybrid system, while a derivative-free algorithm was used for the expense, optimal size, and emission assessments. While developing the microgrid, load following (LoF) and cycle charging (CyC) control were employed. The microgrid is supposed to have a 23.31 kW peak load requirement. The estimated microgrid’s levelized cost of energy (LE), its net present cost (NC), its operating cost, and its annual harmful gas emissions were estimated in this work. Additionally, since the microgrid is grid-connected, the amount of energy output that might be exported to the grid was also estimated, which will potentially increase during blackouts. The power system responses found in this study ensure that the various microgrid components’ voltage, frequency, current, and power outcomes are steady within the designated range, making the microgrid practical and robust.

An analysis of online learning and teaching at the Department of Electronic Engineering at a university of technology during the coronavirus pandemic in South Africa

The Department of Electronic Engineering at a South African University of Technology is currently conducting a research study to investigate the challenges associated with online teaching during the COVID-19 epidemic. Specifically, the study focuses on the perspective of educators in this context. In response to the outbreak, governments worldwide implemented nationwide lockdowns to curb the spread of the virus, leading educational institutions, including universities, to cease in-person instruction. This sudden shift disrupted the educational system, necessitating a rapid transition from traditional face-to-face teaching to online methods to fulfill the curriculum requirements. As faculty members encountered various difficulties in adapting to online teaching pedagogy, the research study concentrates on them as the primary participants. The research study provides recommendations that offer valuable guidance for improving the effectiveness of online teaching practices which may be applied outside of the pandmic to most online teaching pedagogies.

Influence of Infrastructure on Implementation of E-Learning in Technical Vocational Education and Training Institutions in Uasin Gishu County, Kenya

Worldwide e-learning has emerged as a leading channel of learning but its implementation in Kenya has not been successful. Studies have noted infrastructural challenges in implementation of e-learning, an aspect the present study sought to address. The study determined infrastructural factors that influence implementation of e-learning in TVET institutions in Uasin Gishu County. The study established the extent to which the following factors affect the effective implementation: the availability of good bandwidth; quick response time in uploading and retrieving content; fast processors; high performance features on the servers; accessibility of learning management system and the availability of electronic learning equipment. The study was guided by Roger’s theory of Diffusion of innovation and adopted an explanatory research design with a target population of 94 electrical and electronic engineering trainers and 6 HoDs of electrical and electronic engineering departments from public TVET institutions from Uasin Gishu County. Data was collected by use of questionnaire, observation and interview schedule. The piloting of the tools was done in Kitale National Polytechnic to test for reliability and validity. Quantitative data was analyzed by use of both inferential and descriptive statistics using SPSS version 25 while qualitative data using themes and sub-themes. The inferential statistics used included: simple and multiple regression, Pearson’s correlation and Analysis of Variance (ANOVA) while descriptive statistics included mean, standard deviation and frequencies. From the findings, the coefficient of determination (R square) of .449 indicated that the model explained only 44.9% of the variation or change in implementation of e-learning. The study findings indicate that infrastructure (t =2.589, P<.05), significantly influence the implementation of e-learning in TVET institutions in Uasin Gishu County and it is therefore important for TVET institutions to consider strengthening the infrastructure requirements for e-learning.

Design and Implementation of Solar Power and an IoT-Based Pisciculture Management System

Introduction: Pisciculture means fish farming for commercial purposes in a pond or in an artificially created fish tank. Proper care is needed for optimum fish yields.
 Aims: The present research aims to design, simulate, implement, and test a low-cost pisciculture monitoring system to get the environmental status of a fishing pond where aquatic plants and fishes reside. The objective of this work is to produce high-quality and high yields of fish in the pond keeping the standard or prescribed states of the pond water.
 Study Design: The factors that affect the pond environment are flow rate, pH level, oxygen level, temperature, humidity, etc. To get high yields of fish from a pond, these factors must be within a specified level. If the values of these parameters go below or above the prescribed level then the water loses its quality and thereby fishes find it very difficult to survive in that pond because each water quality factor affects the health conditions of fish. Therefore, it is necessary to monitor these parameters.
 Place and Duration of Study: Department of Electrical and Electronic Engineering, Southeast University (SEU) between June 2021 and April 2022.
 Methodology: In this work, we have designed an automated microcontroller, IoT, and solar power-based water quality monitoring system for a fishpond. The automated system restores the values of these factors automatically when any of these factors fail to maintain their level in the pond.
 Results: After testing the prototype of the system, we found that the designed system is performing very well and showing different parameter values in the LCD screen as outputs.
 Conclusion: The system is in expensive and therefore, may be employed in practice.

Research is now being done on soft electroactive polymers (EAPs), such as polyvinyl chloride (PVC) gel, as an example, for use in soft robotics and smart sensors. Although the sensing behavior of PVC gel has not yet been thoroughly investigated, it has been determined that this material reacts in some way to the stimuli that come from the outside. PVC gels are being utilized to construct a broad variety of different kinds of smart sensors due to the fact that their deformation may be endlessly configured by variations in electrode arrangement, applied mechanical stress, and the amount of plasticizer contained within the gel. In this study, experimental characterizations and the results of finite element simulations are discussed for a PVC gel compression sensor. The finite element simulation of what happens to PVC gel when it is compressed from the outside using mechanical force has been built using the COMSOL Multiphysics, which is a finite element simulation software. Additional experimental measurements of PVC gels are carried out in order to validate the underlying principles that have been presented thus far by providing context for the results of the simulations and to validate the findings effectively. Based on the findings, it appears that the suggested sensor is able to detect compression at a variety of amplitudes and rates . This study sheds light on the sensing capabilities of PVC gel in sensing investigations and provides a framework for conducting such investigations, thereby laying the groundwork for an increase in the use of PVC gel sensors in soft robotics research in the future.
