Video conferencing allows people to simulate face-to-face conversations by integrating duplex transmission real-time audio and video with a computer system. IPv6 (also known as IPng-ng for new/next generation), provides 128-bit addressing (that is billions upon billions of addresses), compatibility with IPv4 addresses, security and authentication, quality of service (reserving bandwidth), plug-and-play for network device configuration, hierarchically structured routing and an ability to integrate seamlessly with the current IP during the transition stages. Using IPv6 protocol, improvement in frame and transmission rate and bandwidth usage are expected. A video conferencing system using the Linux platform running in the IPv6 and IPv4 environments has been implemented. Two computers with the Linux operating system (IPv6 enabled) are used to run video conferencing. The implementation of video conferencing is carried out with aid of vic tools (see http://www-mice.cs.ucl.ac.uk/multimedia/software/). In conclusion, the quality of service, especially in frame rate and transmission rate, is more guaranteed if video conferencing is run in the IPv6 environment.

In this paper, reactive navigation of an autonomous guided vehicle (AGV) is described using the fuzzy logic technique. Typically AGV has the ability to operate and move purposely without human intervention and reactive navigation is one of the robot navigation methods used in dealing with the uncertainties and ambiguity of the information of the path that the robot traverses. Fuzzy logic is chosen to control the AGV due to its strength in incorporating the knowledge of an experienced operator. Two fuzzy controllers are designed for controlling the steering angle and speed of the AGV. These will be based on the distance and angle of obstacles. The navigation simulation will be performed using MATLAB.

For the first time, the problem of scheduling divisible loads in a single-level tree network in the non-blocking mode of communication is considered. All earlier studies in divisible load scheduling have considered the blocking mode of communication. A closed-form expression for the processing time in non-blocking mode of communication is derived. Using this closed-form expression, this paper analytically proves a number of significant results on load sequencing and processor-link arrangement in a single-level tree network.

Natural language processing is part of the artificial intelligence domain. Basically, natural language is the language used everyday in our communication either in the form of writing or speech. Thus, this paper attempts to apply natural language to a machine (computer), so that it can be processed and interpreted in a human-like manner. However, up to now, this goal has not been achieved. This research considers the implementation of natural language in a flight schedule query system in order to increase the capability of natural language processing.

This paper discusses the derivation of the total unaligned permeance model of the air-gap between the stator and rotor teeth of a single tooth per pole 6/4 configuration switched reluctance motor (SRM) using simplified 3-D assumed flux path (AFP) method. All the effective mutual and leakage flux in the air-gap region in the X-Y-Z planes are all being considered in the permeance calculation. The flux linkage path patterns are based from those derived by the finite element (FE) simulation. This allows a simple, fast and accurate estimation of the flux linkage to be achieved for used in the development of the motor magnetisation characteristics data. The results obtained using the developed permeance model are compared with those derived by other known methods. From the comparison, it is observed that the developed model is capable of producing reliable and accurate output results without having to use any correction factor.

Human fingerprints have been considered as a unique signature certifying one's identity. Fingerprint verification is currently the most popular technique of biometric personal identification. As a biometric proof of identification, an alignment-based minutiae matching algorithm has been widely investigated, however, not many have considered fingerprint identification using image based verification. An image-based approach does not use minutiae features for fingerprint matching. This project investigates fingerprint-scanned image verification via an inverse fast Fourier transform after a thinning process. The technique may be applied directly to a gray-scale fingerprint image without pre-processing. This correlation coefficient approach is capable of finding correspondences between the input fingerprint image and the stored enrolled template with higher computational efficiency than the minutiae-based method. It has the ability of robust fingerprint verification subject to external conditions. In this paper, the design and implementation of a prototype of an automatic verification system is presented. The high matching rate achieved in this project suggests that an efficient small-scale fingerprint verification system is feasible.

This paper describes a new method for classification of transient disturbance via fuzzy logic incorporated with wavelet processing. The transient is one of the major causes of power quality issues that have been experienced by the utility and consumer parties. The ability of a wavelet to detect the transient disturbance is being exposed. Finally, the fuzzy logic MATLAB is being proposed as a classification tool to differentiate between oscillatory and impulsive transient. This paper is an initial step towards auto-detecting the real-time power quality classification in a real time monitoring system.

Distributed control systems play major roles in real-time applications. In some circumstances human lives may depend on these systems. Hence, they should be highly dependable. Since there is no specific way to forecast a failure, the systems should have fault-tolerant features to allow them to continue to operate in the presence of fault. In this research, a fault-tolerant architecture for real-time distributed control system was developed. A fault-tolerant node was designed and its performance was evaluated using the Markov chains model. All these nodes communicate via a network. To choose the most suitable network for this system, several networks were analyzed qualitatively. Several medium access control protocols were also compared quantitatively using OMNET++. From the results obtained, a new fault-tolerant architecture is proposed. This system possesses high reliability not only at the node stage but also at the network stage, hence increasing the reliability of the overall system.

Methods available for measuring the water quality of rivers, lakes, reservoirs, etc. involve the collection of water samples for these water bodies and subsequent chemical laboratory analysis. These methods and technologies provide accurate measurements and evaluation of water quality for a point in time and space; they are time consuming, expensive and do not provide either the continuous, spatial or temporal view of water quality needed for monitoring, assessing, or managing water quality. In this paper, the measured complex reflection coefficients and complex permittivity (dielectric constant and loss factor) of water using a microwave open-ended rectangular waveguide system called microwave reflectometer system (MRS) is used to monitor the water quality. MRS uses the electromagnetic properties of water to indicate the quality parameters of waste. This system offers the potential of relatively inexpensive, frequent, continuous and synoptic measurements using sensors immersed in the water bodies (reservoirs, rivers, lakes, treatment plant). Dielectric properties of water of different salinity are measured and evaluated.

This research is to study, measure and analyze the signal strength for Celcom GSM [019] and Maxis [012] in UiTM Shah Alam campus. Measurements and data collection of the signal strength is done using TEMS investigation equipment provided by Celcom (M) Sdn. Bhd, Kelana Jaya and Maxis. TEMS is a tool for setting up and maintaining a mobile cellular network. It measures the received signal strength from the 'base transceiver station' (BTS) in terms of ERP (effective radiated power). Global Positioning System (GPS) equipment is also used to get the coordinate and elevation at 31 points throughout campus. For one selected point, measurement is taken in the morning, afternoon, evening and night to see if there is any variation in the signal strength at different times. Data analysis includes comparison between signal strength and position, time, elevation and distance from base station. Some recommendation is given to improve the radio coverage in UiTM area.
