IMPLEMENTATION OF WIRELESS LAN IN UTP

This paper, entitled Implementation ofWireless LAN in UTP environment, looks into the way to implement wireless network in UTP. The main objectives ofthis project are to provide mobile network and internet access using university's network system to students and lecturers and to make it easier and convenient for student to download lecture notes and for lecturers to upload them. Currently, there is no wireless LAN access in UTP environment that can be use by students and staff as alternative opportunity to access and share instant information. Therefore, this project research area is to find out the way to implement wireless LAN using secure Wi-Fi in UTP external environment. For this study, the scope is narrow down to the architecture and design ofwireless LAN network and its developing methodology. Anetwork simulation tool called Network Simulator version 2, or simply known as ns-2, is used to test the efficiency and functionality ofthe designed network.

Sintesis dan pencirian kompleks fenolbenzimidazol dan kajian interaksi terhadap CT-DNA

Kompleks fenolbenzimidazol berjaya disintesis dan dicirikan menggunakan spektroskopi resonans magnet nukleus (RMN), spektroskopi inframerah transformasi Fourier (FTIR), penentuan julat takat lebur, analisis ultralembayung-boleh nampak (UL-BN), analisis unsur (CHNS), kerentanan magnet dan Kristalografi Sinar-X. Mod pengikatan interaksi antara kompleks fenolbenzimidazol dengan DNA timus anak lembu (CT-DNA) dikaji dengan kaedah pentitratan DNA menggunakan serapan elektronik UL-BN dan kajian nisbah kepekatan DNA menggunakan analisis pendarfluor. Berdasarkan spektrum UL-BN, anjakan hipokromism dan batokromism diperhatikan apabila kompleks fenolbenzimidazol dititratkan dengan CT-DNA dan menunjukkan pembentukan kompleks baru. Kompleks fenolbenzimidazol berinteraksi dengan CT-DNA secara pengikatan interkalasi dengan pemalar pengikatan, Kb (1.68 ± 1.4) × 105 - (1.02 ± 0.1) × 107 M-1. Kajian pendarfluor dijalankan untuk memerhati sifat optik kompleks fenolbenzimidazol terhadap CT-DNA. Keputusan kajian ini sangat bernilai dan berpotensi dalam menjadikan kompleks fenolbenzimidazol sebagai prob DNA sensor optik

The Impact of Parenting Styles, Peers, and Teachers on Internet Usage and Addiction among Secondary School Students in Sekolah Menengah Kebangsaan Ibrahim

The internet usage and addiction of the students has been the area of concern since internet has been used in teaching and learning approach in this new era. Therefore, this study was conducted to identify the influences of parenting styles, peers, and teachers on internet usage and addiction among secondary school students in Johor, Malaysia. This research was carried out using a quantitative method in which 200 students from ages 13 to 17 were selected randomly to take part in answering the survey form. The number of respondents was determined by using Krejcie and Morgan (1970) method of sampling. The survey form was divided into five parts, Part A demography, Part B internet usage and addiction, Part C influences of parenting styles, Part D influences of peers, and Part E influences of teachers. The reliability and validity for each of the variables were measured using Cronbach’s alpha where all four variables are said to have α > 0.5. Part B with (α= 0.883), Part C (α= 0.851), Part D (α= 0.744), and Part E with (α= 0.695). Based on the findings, it has been identified that the most dominant factor of parenting style is the permissive style as it has the highest value of mean, 3.72 compared to authoritarian (3.32), authoritative (3.52), and neglectful (3.25). This study showed that the involvement level of peers is moderate with the mean value of 3.42 and as well as teachers’ involvement (3.24). While parenting styles, peers, and teachers are good predictors of internet usage and addiction among secondary school students. with the value F (2,97) = 35.24 P<0.05. These three independent variables, which are parenting styles, peers, and teachers predicted internet usage and addiction among secondary school students. Given this, all three variables (e.g., parenting styles, and peers and teachers) have an impact on students' addiction to the internet. The implications of the study where it could raise parents’ and public awareness and understanding to minimize internet addiction among the younger generation. While for students, it can boost their self-esteem to prevent peer pressure, which can lead to internet addiction. With the limitation of this study, further research could be conducted especially on how parents and educators could monitor and control the internet usage, also the effects of internet addiction to students’ mental health

Effect of Multi-DG Installation to Loss Reduction in Distribution System

Since last decade, Artificial Intelligence (AI) methods have been used to solve complex DG problems because in most cases, they can provide global or near global solution. The major advantage of the AI methods is that they are relatively versatile for handling various qualitative constraints. AI methods mainly include Artificial Neural Network (ANN), Expert System (ES), Genetic Algorithm (GA), Evolutionary Programming (EP), Ant Colony Optimization (ACO) and Particle Swarm Optimization (PSO). The purpose of this paper is to present a new technique, namely Adaptive Embedded Clonal Evolutionary Programming (AECEP). The objective of the study is to employ AECEP optimization techniques for loss minimization. This technique was developed to optimally determine the location and sizing of DG. The IEEE 41- Bus RTS was implemented for testing several cases in terms of loading conditions

Addressing Gaps for Health Systems Strengthening: A Public Perspective on Health Systems’ Response towards COVID-19

Strengthening the health systems through gaps identification is necessary to ensure sustainable improvements especially in facing a debilitating outbreak such as COVID-19. This study aims to explore public perspective on health systems’ response towards COVID-19, and to identify gaps for health systems strengthening by leveraging on WHO health systems’ building blocks. A qualitative study was conducted using open-ended questions survey among public followed by in-depth interviews with key informants. Opinions on Malaysia’s health systems response towards COVID-19 were gathered. Data were exported to NVIVO version 12 and analysed using content analysis approach. The study identified various issues on health systems’ response towards COVID-19, which were then mapped into health systems’ building blocks. The study showed the gaps were embedded among complex interactions between the health systems building blocks. The leadership and governance building block had cross-cutting effects, and all building blocks influenced service deliveries. Understanding the complexities in fostering whole-systems strengthening through a holistic measure in facing an outbreak was paramount. Applying systems thinking in addressing gaps could help addressing the complexity at a macro level, including consideration of how an action implicates other building blocks and approaching the governance effort in a more adaptive manner to develop resilient systems

Optimal TCSC Allocation via Chaotic Immune Symbiotic Organisms Search for Voltage Profile Improvement

As the load demand in a power system increases, power system operators struggle to maintain the power system to be operated within its acceptable limits. If no mitigation actions are taken, a power system may suffer from voltage collapse, which in turn leads to blackout. Flexible AC Transmission System (FACTS) devices can be employed to help improve the voltage profile of the power system. This paper presents the implementation of Chaotic Immune Symbiotic Organism Search (CISOS) optimization technique to solve optimal Thyristor Controlled Series Compensator (TCSC) in a power system for voltage profile improvement. Validation process are conducted on IEEE 26-bus RTS resulting in the capability of CISOS in solving the allocation problem with a better voltage profile. Comparative studies conducted with respect to Particle Swarm Optimization (PSO) and Evolutionary Programming (EP) has revealed the superiority of CISOS over PSO and EP in solving the optimal allocation problem by producing optimal solution with a better voltage profile. The results and information obtained from this study can help power system operator in terms of optimal compensation in power system as well as improving the operation of a power system
