Abstract

This paper presented the design and development of a multilevel inverter (MLI). The demand for better electronic devices increases rapidly. The multilevel inverter (MLI) which convert direct current (DC) to alternating current (AC) are widely used in the industry. The objective of this research is to design and simulate the 3-level and 3-level NPC MLI module using PLECS software. To develop the switching technique for each level of NPC MLI, and To analyse and validate the MLI in terms of harmonic. Although there is already an inverter in the market, the researcher still pursues to improve the efficiency, total harmonic distortion (THD), and reduce the size of the MLI. An THD can be improved using the suitable modulation technique and the size of the MLI can be reduced by designing better topologies. The modular NPC is using the three-level NPC as the main module and the number of levels can be increased by adding 2 level NPC modules to the main module. The switching technique was created to control the NPC MLI for each level.

Home Monitoring System Design Using Wireless Sensor Networks and Smart Cameras Abstract: A wireless Sensor Network is a wireless network that facilitates an interface that provides connectivity between various nodes and existing wired systems. WSNs are used in many real-time household, industrial and research fields for monitoring and control. This paper is conducted to study home monitoring using WSN and smart cameras. The objective of the study is to improve home security with a home monitoring system using WSN and smart cameras, to develop a system that can remotely monitor and control home appliances and help reduce crime rates in residential areas. The use of Wireless Sensors is increasing, and new concepts and applications are being demonstrated, some fundamental issues remain unresolved. Although many of these issues do not need to be resolved for proof of concept designs, they are important issues to address when referring to the long-term operation of these systems. One of these issues is the lifetime of the system, which is related to the lifetime of the nodes, on which the system is composed. Based on the output of the questionnaire distributed to 100 respondents, it was found that the mean value was 0.56 for knowledge and awareness about home monitoring using WSN and smart cameras.

Abstract

Swarm robotic is well known for its flexibility, scalability and robustness that make it suitable for solving many real-world problems. Source searching which is characterized by complex operation due to the spatial characteristic of the source intensity distribution, uncertain searching environments and rigid searching constraints is an example of application where swarm robotics can be applied. Particle swarm optimization (PSO) is one of the famous algorithms have been used for source searching where its effectiveness depends on several factors. Improper parameter selection may lead to a premature convergence and thus robots will fail (i.e., low success rate) to locate the source within the given searching constraints. Additionally, target overshooting and improper initialization strategies may lead to a nonoptimal (i.e., take longer time to converge) target searching. In this study, a modified PSO and three different initializations strategies (i.e., random, equidistant and centralized) were proposed. The findings shown that the proposed PSO model successfully reduce the target overshooting by choosing optimal PSO parameters and has better convergence rate and success rate compared to the benchmark algorithms. Additionally, the findings also indicate that the random initialization give better searching success compared to equidistant and centralize initialization.

Abstract

Technological developments have brought about a paradigm shift in the world of education. The education system must be more open and flexible, where students can experience these opportunities according to their skill level. 21st-century education and the application of the elements of Revolution 4.0 Industry in education realize that initiative. The Bayesian Network approach is becoming one of the essential tools in the development of educational applications. Therefore, the persistence of this systematic review is to identify peer-reviewed literature on the Bayesian network approach in education. Scopus and Web of Science, and IEEE citation databases are used in the data-gathering phase. PRISMA approach and keyword search were obtained and analyzed. This bibliographic data of articles published in the journals over ten years were extracted. VOS viewer was used to analyzing the data contained in all journals and articles. This systematic review shows that the development in education can absorb the changes that occur in technology. The findings from 1160 articles extracted show that using the Bayesian approach in the development of educational applications improves the quality of use, especially from the point of students. The level of predictive accuracy generated through the Bayesian network approach improves the quality of educational application development. However, the study's findings indicate that there is scope for research related to the application and use of this approach in the development of educational applications.

Abstract

In education, the use of smart-phone apps is very helpful in the process of teaching and learning. Therefore, this situation inspires and opportunities for the development of a smart-phone app namely the Electrical e-Wiring Module (called, MePE). The MePE app is a smart-phone app or mobile apps developed to help students who are taking electrical wiring courses to refer how to learn electrical wiring via smart-phone applications. In addition, this application can also be used as a teaching tool in the process of learning electrical wiring. The study was conducted to identify the requirements for MePE app, develops and tests the functionality of MePE app. There are four main sections in this application. This application is developed in accordance with the evolutionary prototype methodology. As a result of the functionality testing performed on the nine functions available on the MePE app all the functions passed the tests that have been performed. In addition, 24 of 31 respondents agreed that the MePE application is helpful and effective in learning electrical wiring. It is hoped that with this application it will help students that study electrical wiring courses to make reference to electrical wiring through this application.

Abstract

Augmented reality is known as a type of technology that improves the physical world through computer-generated content that can be applied in mathematics education. The primary objective is to review and explore existing research on the characteristics of augmented reality (AR) learning through a systematic literature review (SLR). The study identified various research papers that discussed the utilization of AR in mathematics education, as well as studies that assessed the effectiveness of AR learning in this domain. The review process involved identification, screening, eligibility, inclusion, and data analysis using three search engines: Springer Link, Scopus, and Science Direct. The study adhered to the PRISMA guidelines for reporting. A total of 20 articles were selected from the included studies after sorting. The findings revealed that AR learning was distributed in studies in terms of trends and countries. There were several features or characteristics in AR learning and AR learning was implemented in different areas of mathematics, such as Trigonometry, STEM, Linus Mathematical Modeling, Calculus, Geometry, Statistics, and Algebra. Besides that, teacher preparation in using AR to teach mathematics learning also will be a focus. This SLR also states the challenges or limitations of AR learning. In conclusion, Augmented reality has emerged as a promising tool for mathematics education, enhancing student engagement, comprehension, and problem-solving abilities by providing immersive, interactive, and visual learning experiences.
