Performance Comparison between Two Electrodes and Three Electrodes MEMS Capacitive Switch using Architect Coventorware

This paper presents the electromechanical and RF performance comparison between two electrodes and three electrodes MEMS capacitive switch using Architect Coventorware. The important of this study is to react to the industries in providing low actuation voltage MEMS capacitive switches with low loss and high isolation and make it possible to be integrated with CMOS circuit. MEMS capacitive switches with three different support structure namely fixed-fixed beam, single meander and double meander have been designed and simulated in both standard and proposed structure. A standard switch consists of two parallel electrodes and a proposed switch consists of three parallel electrodes. Designing using schematic capture begin by selecting the suitable component from electromechanical library to represent membrane, support structure, anchor, bottom electrode, top electrode, ground, transmission line-in and transmission line-out. The schematic diagram has been simulated and translated to 2D layout and 3D model for physical verification. The electromechanical analysis has been carried out using DC Transfer Analysis. In DC Transfer Analysis, the value of pull-in voltage, up-state and down-state capacitance can be attained. In Small Signal Frequency Analysis the value of resonant frequency is obtained. The measurement of RF performance was done using RF Electrical Analysis. Simulation result shows the pull-in voltage for all proposed design has been reduced 40%-50% as compared to their standard counterpart. While the result for other performance including capacitances for three electrodes switch has almost same value as two electrodes structure. The switch indicates low insertion loss (<-0.4db) in the up-state position and high isolation (>-26dB) in the down-state position. This concludes that the additional top membrane does maintain the good electromechanical and RF performance of MEMS capacitive switch

Profil personaliti pelajar-pelajar program matrikulasi Universiti Putra Malaysia

This descriptive study was conducted to determine the pattern of personality profile amongst the students of matriculation programs in Universiti Putra Malaysia, Serdang, Selangor. This study also aimed to determine whether there were any differences in personality between male and female students according to specialization areas. The subjects of this study were 340 students who were selected using the stratified random sampling from a total of 1475 students of Science, Engineering, Medical, Accounting and TESL matriculation programs. The instrument used in this study was the Sidek Personality Inventory (IPS). The data obtained were then analysed using the descriptive statistic including the mean, standard deviation and frequency. The finding of this study was that each specialization area has shown the same personality pattern. The finding clearly indicated that some major traits of personality which were identified as the ideal personality for the student in higher education such as analytical, intellectual, and endurance traits were only at the medium level whereas for the dependent and self-critical traits, it was quite high. The finding also indicated that there were no significant differences in personality traits based on specialization area and gender of the students. Pertaining to the research findings, several implications and recommendations were put forward

Cabaran membina kemajuan bangsa Melayu dalam matahari memancar tarikh kerajaan Jepun (Challenges to Malay`s progress in matahari memancar tarikh kerajaan Jepun )

Abdullah Abdul Rahman, a religious scholar from Johore, had written about the progress of the Malays in the early 20th century. From 1932 to 1947 he held the post of Head of Johor Religious Department. This article analyzes a work of Abdullah Abdul Rahman, Matahari Memancar Tarikh KerajaanJepun, emphasizing the social aspect, mainly, of the challenges in bringing about progress to the Malays. This study adopts a qualitative approach through document analysis looking at textual materials as the prime sources for this study. This study suggests that Abdullah Abdul Rahman emphasizes the achievements of the Japanese as a committed people in building a nation, whereas the Malays are portrayed as dependent on the colonial master, especially in governance and defence of the state. Apart from that, this study underlines two important characteristics of the Japanese culture then; wisdom and self-confidence. Besides, the significance of this study is substantiated as the positive characteristics of the Japanese could be emulated by the Malays to generate development and progress. In addition, the characteristics have proven to have brought development to the Japanese. The effort to emulate and learn from the achievements and development of the Japanese was when the Malaysian government introduced the Look East Policy in 198

An application of the Sidek module development in rebt counseling intervention module design for orphans

This article introduces Rational Emotive Behavior Therapy Self-Concept for Adolescents (REBT-SC-A). The main objective of this REBT-SC-A is to assist orphans in Malaysia to develop a positive and healthy self-concept. The Sidek Module Development Model (SMDM) and Rational Emotive Behavior Therapy theory are applied as a guideline in developing REBT- SC-A. A validation stage was carried out by five expert counselors, and Cronbach alpha .80 was obtained. A group of orphans from aged 13 to 17 years was piloted to check the module's reliability and the Cronbach alpha .93 was obtained. Implications of the study are discussed later in the article

Design and implementation of a digital front-end for multi-standard software defined radio receiver

Software defined radio (SDR) is an emerging technology, thought to realize flexible radio systems, multi-service, multistandard, re-configurable and reprogrammable by software (Buracchini,2000). A goal in SDR is to push the digitization point as close as possible to the antenna (Hentschel et. al.,1999)

COVID-19 and the Palm Oil Industry: Navigating recovery

This article unfolds the current state of the palm oil industry following the COVID-19 pandemic. Despite the industry being allowed to operate given strict standard operating procedures, palm oil production has depicted a declining trend since 2018. One of the contributing factors is foreign worker shortages for maintenance and palm oil harvesting. Therefore, this article proposes the mechanization and mobilization of local workers, as well as the challenges and the way forward for Malaysia. Keywords: 2M-mobilization and mechanization; palm oil plantation; challenges; way forward eISSN: 2398-4287 © 2023. The Authors.
