Worst month rain statistics measurement in Malaysia
- Trang 12-14
Excess attenuation due to rainfall is one of the most important constraints to the performance of microwave radio links. In temperate climates at frequencies above 10 GHz, rainfall rates have significant effects on the performance of microwave radio links. Therefore, the behavior of radio communication links varies seasonally over a year. This paper presents on the results obtained from the analys......

Ternary decision diagrams
- Trang 76-79
TDD graph-based representation is actually a natural extension of the binary decision diagram (BDD) to the three-valued case. This paper describes a method of defining, analyzing, and implementing the Boolean function using a ternary decision diagram (TDD). This diagram representation enables us to evaluate a Boolean function. We investigate the characteristics of different types of TDDs in order ......

Development of simple PWM inverter using photovoltaic cells
- Trang 297-300
This paper presents the development of a simple 1.5 kW single-phase sinusoidal pulse width modulation (PWM) inverter. This inverter is designed to be either a stand-alone or grid connected inverter from a direct supply of photovoltaic (PV) cells. The developed inverter unit converts the DC input supply from the PV cells into a clean sinusoidal voltage output. This power inverter is also capable of......

Nonlinear function approximation using radial basis function neural networks
- Trang 326-329
Radial basis function neural networks (RBFNN) which are best suited for nonlinear function approximation, have been successfully applied to a wide range of areas including system modeling. The two-stage training procedure adapted in numerous RBFNN applications usually provides satisfactory network performance. Though this method is proven to allow faster training and improves convergence, the init......

Vibration faults simulation system (VFSS): a system for teaching and training on fault detection and diagnosis
- Trang 15-18
Machine condition monitoring is vital in many plants as any shutdown can lead to both materials and financial losses. Since vibration fault signals and their causes are important for fault detection and diagnosis, a vibration faults simulation system (VFSS) is developed to gain good understanding of vibration faults signals. This paper is aimed at simulating and analyzing vibration fault signals, ......

Reliable multicast service with IPv6 support: synchronous collaborative applications
- Trang 468-471
The world wide web (WWW) already accounts for more Internet network traffic than any other application, including email and simple file transfer. It is also a collaborative technology in a weak sense of the word - it allows people to share information. Synchronous collaboration is where an interactive activity is simultaneous and in real-time. Computer based synchronous collaborative systems like ......

A motion region estimation technique for Web camera application
- Trang 352-355
This paper presents the steps involved in processing the output image obtained from image subtraction. A Web camera or Web cam is used as a video clip capture device and MATLAB version 6.01 with Image Processing Toolbox is used as the analysis software. Image frames extracted from the video clips undergo image subtraction for motion detection purposes. The continuous steps presented in this paper ......

An investigation into the effect of metal and substrate thicknesses on the performance of m-derived MMIC lowpass filter
- Trang 403-406
Describes the investigation of MMIC filter response using Libra simulator. The filter demonstrates a maximally flat passband with a cut-off frequency of 10 GHz. It is built on silicon and has a size of 1.296 /spl times/ 1.6 mm/sup 2/. The specified passband and stopband insertion losses are 0.2 dB and greater than 20 dB respectively. m-derived filter methodology and circuit configurations supporte......
