This paper presents the combination of two different methods to perform the waveform analysis for PWMoperated inverter. The two techniques are Newton-Raphson method and Curve-Fitting as a PWM concept to operate PWM-based inverter, the proper solutions of switching angles can be valuated initially by using the Newton-Raphson method with the wide-ste

This paper presents the additional ways to figure out the switching angles for eliminating harmonic in Modular Multilevel Converters, MMCs. The switching angles equation is written in terms of nonlinear equation system, in general, one of the numerical method, named Newton-Raphson method, is used for this calculation procedure but the Newton-Raphso

This review paper deals with the previous and current wastewater treatment plant modelling. The future of semantic modelling in a wastewater treatment plant through a new approach, Artificial Immune Systems (AIS), is introduced. AIS is still in the infant stage of soft computing. However, it has gained its popularity in the recent years, especially

Diabetes mellitus (DM) patients who achieved treatment target HbA1c ≤ 6.5% was 17.4% in Malaysia. Prevalence of DM patients with periodontitis co-morbidity (DM-P) in Malaysia was 53.3%. Effectiveness of non-surgical periodontal therapy (NSPT) on glycemic control of DM-P patients has been reported in previous studies.This study verified effect of

This study is an attempt to gather and investigate in depth information on Malaysian university students’ use of the English language in their daily interactions. Essentially, it is a qualitative phenomenological study that utilizes the interview as a tool to gather information from undergraduates of a Malaysian public university based in the Kla

Purpose -The objective of the meta-analysis was first to substantiate the magnitude of the effect size (ES) of the relationship between mastery experience and teacher self-efficacy. Second, the meta-analysis was also aimed to search for the research characteristics that moderate the mastery experience-teacher efficacy relationship. Methodology - A

At present, two important processes, namely CNC machining and rapid prototyping (RP) are being used to create prototypes and functional products. Combining both additive and subtractive processes into a single platform would be advantageous. However, there are two important aspects need to be taken into consideration for this process hybridization.

We report an investigation on Bose-Einstein condensates with two-body (cubic) and three-body (quintic) interactions in the corresponding nonlinear Schrodinger equation, considering s-wave two-body scattering length as periodically varying in time. For the quintic interacting term, the dependence on as was considered within two models, being quadrat

The present study compared conventional (maceration) extraction (EtOHconv) and supercritical fluid extraction (SFE) methods as a mean of comparing conventional and green process for a weed namely Mimosa pudica L. to obtain a safe antidiabetic natural agent. In vitro analysis comprised of two different assays, antioxidant assay (determination of tot
