In this paper, swarm and evolutionary algorithms have been applied for the design of digital filters. Genetic algorithm (GA) and an improved Particle swarm optimization (PSO) called Particle Swarm Optimization with Constriction Factor and Inertia Weight Approach (PSOCFIWA) have been used here for the design of linear phase band pass finite impulse response (FIR) filters. The fitness function is based on the squared error between the actual and the ideal filter response. PSOCFIWA seems to be promising optimization tool for FIR filter design especially in a dynamic environment where filter coefficients have to be adapted and fast convergence is of importance. Digital filter plays an important role in today's world of communication and computation. On the other hand, to design a digital finite impulse response (FIR) filter satisfying all the required conditions is a challenging one. In this paper, we have introduced an iterative method to find the optimal solution of optimal FIR filter design. FIR filter design is a multi-modal optimization problem. The conventional gradient based optimization techniques are not efficient for digital filter design. Given the filter specification to be realized, PSOCFIWA algorithm generates a set of filter coefficients and tries to meet the ideal frequency characteristic. In this paper, for the given problem, the realization of the FIR band pass filters of different order has been performed. The magnitude responses are demonstrated for the different design techniques of digital FIR filters. The simulation results have been compared with the well accepted evolutionary algorithm such as genetic algorithm (GA). The results justify that the proposed FIR filter design approach using PSOCFIWA outperforms to that of GA, not only in the accuracy of the designed filter but also in the convergence speed and solution quality.

This paper presents a prototype of the channel coding algorithms with a baseband modem for TMS320C6713 implementation purpose. It is essential to use channel coding in baseband signal in order to reduce the error of the received signal. In this study, convolutional code (CC) is selected to be the type of channel coding and Viterbi decoder for decoding method. The parameters that have been analyzed in the research are constraint length, modulation techniques and decoding decision. The baseband modem with channel coding is simulated in Additive White Gaussian Noise (AWGN) and the performances of each parameter are compared in terms of Bit Error Rate (BER) with theoretical values. Results from the simulation of the proposed baseband modem are in line with the theoretical results. The successful in uploading process for the baseband modem model into TMS320C6713 DSP Starter Kit (DSK) indicates the model is suitable for implementation purpose and further improvements need to be made in the next research in order to validate the implementation results.

Thermal interface resistance of solids is an important factor for heat conduction from one solid to another. Interface resistance disrupts heat flow in systems like CPUs and various solid state devices like LEDs. Interface materials play an important role in heat transport through an interface. In this study, TiN/Ti with different Ti thickness and Ti/TiN was coated on a copper substrate. In general all samples show increase in overall thermal conductivity as pressure was increased. The overall thermal conductivity of the material is measured at different contact pressures. It was observed that by switching the order of the coating, overall thermal conductivity changed drastically. It was also observed that thermal conductivity of the sample reduced when coating thickness was reduced.

Cropcam UAV provides GPS based digital images on demand and real time data with high temporal resolution throughout the equatorial region where the sky is often covered by clouds. The images obtained by the UAV system in this research were used to overcome the problem of unclear images obtained by the satellite and manned aircraft in our study area. Conventional classification methods commonly cannot handle the complex landscape environment in the image. The result of each image has often a salt and pepper appearances which are the main characteristic of misclassification. The objective of this study is to evaluate the land use/land cover features over Penang Island using contextual classification method based on the frequency-based approach. The technique was applied to the high resolution images in three bands collected from a digital camera equipped with the platform system to extract thematic maps. Contextual classifier that utilized both spectral and spatial information could be reduce the speckle error and improve the classification performance significantly. Four classes could be classified clearly within the study area, and a high accuracy was achieved in the classification process. In order to evaluate the performance of the classifier, nine different window sizes ranging from 3 by 3 to 19 by 19 with an increment are tested. The study revealed that the frequency based-contextual classifier is effective with the images used in this research compare with the satellite images and images collected from conventional manned platforms and could be used for land use/cover mapping for the small area of coverage.

The purpose of this project is to examine the functionality and efficiency of the manual control mode with the implementation of low cost RF Transmitter and Receiver modules for wireless transmission. A User's Controller Panel as well as a model of robotic wheelchair has been designed and developed to provide the testing of robotic wheelchair locomotion control via wireless data transfer. By using C programming algorithm, PIC16F877 has been used as the Microcontroller unit for robotic wheelchair while PIC16F88 as the Microcontroller unit for User's controller panel. Finally the proposed method on the implementation of wireless data transfer as well as the experimental setup also has been discussed. The results prove that low cost RF modules have the feasibility to be used for simple-one way wireless data transfer with the capability of transmitting several basic instructions to the robotic wheelchair.

This paper presents the feasibility study of implementing Repetitive Observation Strategy (ROS) using a sonar sensor array. ROS is a method that collects observation data taken from different observer positions for anomaly detection purposes. This strategy had never been implemented using sonar sensor. The study is conducted using simulation in MATLAB. The simulation is run by varying the angular resolution of the sonar sensor array which covered 180 degrees. The performance of anomaly detection is analyzed using Receiver Operating Characteristic (ROC) curve. Result shows that the performance of anomaly detection decrease as the angular resolution of sensor increases.

The ability to screen between normal and abnormal bone marrow slide images with high accuracy rate is very much needed before going for the classification of the types and subtypes of Leukemia. Beforehand, the bone marrow slide images will be implemented with digital image processing techniques which include image enhancement, image segmentation and feature extraction. They are 13 features that have been extracted from every white blood cell on both normal and abnormal bone marrow slide images. These extracted features include area, perimeter, radius, circularity, mean value for red, blue and green respectively, standard deviation and variance also from red, blue and green respectively. In this paper, the neural network based classifier, Multilayer Perceptron (MLP) is used for screening task. The MLP network is trained using the Levenberg Marquardt (LM) training algorithm. The extracted features were assigned as data input to the network and the result of the screening has been proven to have high accuracy rate which is 98.667% for training dataset and 94.5% for testing dataset.

This paper proposes an architecture based on Space Vector Pulse-Width Modulation (SVPWM) for fault-tolerant motor controller. The proposed architecture integrates Scalar Control with SVPWM to increase area-efficiency and functionality of the module. The implementation on Field Programmable Gate Array (FPGA) using Verilog increase the area utilization to only 1.5 times compared to the SVPWM and maximum operating frequency of around 60 MHz. The functionality of the design is tested in simulation for constant and variable motor speed and has shown a promising result with error of 0.97% for constant speed and 1.98% for variable speed. Based on the result, the proposed architecture for SVPWM with Scalar Control capability is proven to be a viable option for fault-tolerant design for motor controller when the feedback is absent.
