This paper present the library shelf management system. The system was developed using Radio Frequency Identification (RFID). The research was developed in integrating the RFID system and the creation of Graphical User Interface (GUI) at the host PC. The scope of work of the research is to develop an automatic library shelf management system to assist the librarians for more efficient shelf management to find any misplaced books on the library shelf. GUI for the system was developed using Microsoft Visual Basic.Net. The GUI task is to store details information of the book to the database. Subsequently a Shelf ID was created and coded to the RFID tag. The system then used this code to find any misplaced book on the selected shelf.

Recently, International Center for Global Earth Models (ICGEM) published more than 50 Global Geopotential Models (GGMs). These GGMs plays an important role in a determination of a precise geoid model. Nowadays, some of the models offer high accuracy and better resolution of the gravity field. In this study, several recent GGMs derived from satellite-only (eg. EIGEN) and combined (eg. EGM2008) will be used. Gravity anomalies derived from selected GGMs are analyzed and compared with gravity anomalies derived from terrestrial gravity observation over West Malaysia (WM). The comparison and the results of selected GGMs is shown with the residual statistic. From the results, gravity anomalies derived from combined solution Earth Gravity Model (EGM2008) with the spherical harmonic coefficients up to 2190 is the most suitable model can be use as a reference over West Malaysia.

An adaptive fuzzy variable structure velocity controller of a permanent magnet linear synchronous motor (PMLSM) is designed for a command profile which has rapid change in a wide range. This is performed for comprehensive nonlinear model of PMLSM including non-idealities such as detent force, parameter uncertainty, unpredicted disturbance, and nonlinear friction. The proposed method is based on the adaptive sliding mode control (SMC) enhanced with a fuzzy inference to determine coefficients of the controller. The fuzzy block uses the desired and real velocity, and also its derivative as three inputs and a and C as outputs. A set of 343 rules come together to make a fuzzy rule base which brings a powerful controller with high resolution for different situations. As an evaluation criterion of the performance of the proposed method, a proportional - integral (PI) controller is designed whose parameters are optimally tuned by the particle Swarm Optimization (PSO) algorithm for better comparison.

In this essay a self-oscillating mixer (SOM) is presented fundamental signal generated by the oscillator subcircuit in the mixing process. The core of the oscillator consumes 3mA of current from a 1.8 V DC supply and results in an output power of −0.94dBm per oscillator, and achieved phase noise of −92, −105 and −110dBc/Hz at 100KHz, 600KHz and 1MHz from the carrier, respectively. In the mixing process the presented mixer achieved IIP3 of −8.2dBm with conversation gain of 6.5dB. The circuit was designed and simulated in 0.18-µm CMOS technology by ADS2010.

Changes in stem diameter of orchid plants were investigated in control growing climate. Previous study has focused on stem diameter in relation to plant water on terrestrial plant for outdoor and practice conventional watering by farmers. The objective of this work is to identify the characteristic of orchid stem changes and to relate the stem shrinking rate with orchid plant water content and its microclimate. In this project, strain gauge sensor was employed to measure the changes. Experiments were performed on two different samples of wild orchid, Coelogyne rochussenii and Epidendrum stamfordianum. From the finding, it can relate that changes in voltage strain gauge are related to the stem diameter of orchid plants. In conclusion, single strain gauge can be used in the measurement of the changes in stem diameter orchid plant.

Programmable Logic Controller (PLC) is widely used in manufacturing industries for automation and became one of the essential subjects in the university. Learning theory in class alone is not enough to acquire the knowledge of PLC. Therefore in this paper a PLC Integrated Development Environment (IDE) tool suit is developed to assist students' learning in the class. It consists of ladder diagram editor, simulator and compiler. It also provides an interactive learning in class as well as hand-on activities for laboratories. This software package is developed using Object Oriented Programming (OOP) language Visual Basic 6 to create a virtual microcontroller environment in simulation process.

This paper reports on the study of interference effects from 2 types of Ultra Wide Band (UWB) radar signals on an OFDM transmission system by simulation. The UWB signals were: Gaussian monocycle pulse and UWB chirp signal. Average bit error rate (BER) degradation of the victim system was evaluated under in-band interference from the UWB signals in AWGN channel. Simulation results indicated that Gaussian monocycle pulse degrades the BER characteristic of an OFDM system more severe than a UWB chirp signal, where significant BER floor were observed at the victim receiver. The amplitude probability distributions (APD) of interfering UWB envelope signal at the victim receiver were analyzed.

Worldwide Interoperability for Microwave Access (WiMAX) is a technology that bridges the gap between fixed and mobile access and offer the same subscriber experience for fixed and mobile user. Demand for such type of mobile broadband services and applications are growing rapidly as it provides freedom to the subscribers to be online wherever they are at a competitive price and other significant facilities such as increasing amounts of bandwidth, using a variety of mobile and roaming devices. The earliest version of WiMAX is based on IEEE 802.16 and is optimized for fixed and roaming access, which is further extended to support portability and mobility based on IEEE 802.16e, also known as Mobile WiMAX. However, frequent topology changes caused by node mobility make routing in Mobile WiMAX networks a challenging problem. This paper presented an analysis on those routing protocols especially designed for wireless networks. A study and comparison on the performance of three routing protocols (AODV, DSR, and DSDV) for Mobile WiMAX environment is done. An assumption of each subscriber station has its routing capabilities within its own network is prepared. The performance matrix includes Packet Delivery fraction (PDF), Throughput, End to End Delay, and number of packet dropped were identified. The study used NS2 simulator for the comparison on the performance analysis. Successfully results found that AODV protocol outperform the DSR and DSDV.
全球微波接入互操作性(WiMAX)是一种弥合固定和移动接入之间差距的技术,为固定和移动用户提供相同的用户体验。对这种类型的移动宽带服务和应用的需求正在迅速增长,因为它为用户提供了在线的自由,无论他们在哪里,以具有竞争力的价格和其他重要的设施,如增加带宽,使用各种移动和漫游设备。最早版本的WiMAX基于IEEE 802.16,针对固定和漫游接入进行了优化,并在IEEE 802.16e的基础上进一步扩展,以支持可移植性和移动性,也称为移动WiMAX。然而,由于节点移动性导致的频繁拓扑变化使得移动WiMAX网络中的路由成为一个具有挑战性的问题。本文对无线网络专用路由协议进行了分析。对移动WiMAX环境下的AODV、DSR和DSDV三种路由协议的性能进行了研究和比较。假设每个用户站在其自己的网络中具有其路由能力。性能矩阵包括包交付分数(PDF)、吞吐量、端到端延迟和被识别的丢包数。本研究使用NS2模拟器进行性能分析比较。结果表明,AODV协议优于DSR和DSDV协议。

Demand for such type of mobile broadband services and applications are growing rapidly as it provides freedom to the subscribers to be online wherever they are at a competitive price and other significant facilities such as increasing amounts of bandwidth, using a variety of mobile and roaming devices. The earliest version of WiMAX is based on IEEE 802.16 and is optimized for fixed and roaming access, which is further extended to support portability and mobility based on IEEE 802.16e, also known as Mobile WiMAX. However, frequent topology changes caused by node mobility make routing in Mobile WiMAX networks a challenging problem. This paper presented an analysis on those routing protocols especially designed for wireless networks. A study and comparison on the performance of three routing protocols (AODV, DSR, and DSDV) for Mobile WiMAX environment is done. An assumption of each subscriber station has its routing capabilities within its own network is prepared.
