This paper focused on experimental data and study for the testing of the material mechanical properties using vibration technique. By applying vibration analysis and testing on the material, we could determine the natural frequencies, the damping ratio and mode shapes of the structure. However, in this study, we only considering the natural frequencies of the material as the input data needed for training. As an extension for the study, the system tested with various method of neural network training algorithm. The Levenberg-Marquardt Backpropagation used as the algorithm in an artificial neural network system developed.

One of the important problems in ceramic tile industry is tiles' quality classification with automatic systems by applying machine instead of human. Tiles' quality can be divided into color analysis, dimension verification, and surface defect detection. It's very difficult for human to control all of them, because of harsh industrial environment with noise, extreme temperature and humidity. In this paper, we present a method for visual inspection of ceramic tile corners. We use a method based on image processing techniques and dot product vectors if angle was more than 92 degree or less than 89 degree. Our ceramic is a defective tile. Our algorithm is evaluated on a set of images which has been taken of a Flaw master system in a tile factory and has 12.5% error in both normal and defective tile. The obtained results show efficiency our approach in corner defect detection.

High and accelerating rates of the urban changes and the urban area growth especially in developing countries needs for efficient and fast techniques for map production and revision with the appropriate accuracy. The used of high resolution with ground resolution had changed mapping perception due to its unique characteristics and have a good potential as a data sources for map production. Thus, the mapping potentials of the single IKONOS image had been thoroughly examined on 2D geometric accuracy assessment. Based on overall evaluation, it is found the amount of error and the entire image is have a good geometric planimetric accuracy that regardless to its standard requirement and it is suggested and recommended to be used for large scale map production. Otherwise, the experience gain from this research will eventually highlight the future role of existing technology towards the mapping production in large scale specification for various mapping applications and also may contribute significantly to the topographical data collection process.

This paper presents a study of EEG pattern for different levels of nicotine dependence for smokers based on Theta, Alpha and Beta Band power using Power Spectral Density (PSD). 33 male smokers participated for this research. Participants were asked to fill in the Fagerstrom Test for Nicotine Dependence Questionnaire and EEG data was recorded for 5 minutes. Results show some difference in the Theta, Alpha and Beta Band power of smokers from different levels of nicotine dependence, where medium dependence smokers have a higher Theta, Alpha and Beta Band power compared to low dependence smokers.

This paper discusses about the use of low cost digital camera or known as non metric camera as photogrammetry tool for speeding up the process of acquiring aerial data. Digital camera can also be categorized as non metric camera. In photogrammetry, digital camera has been used for many diversified applications either in aerial photogrammetry or close range photogrammetry. The digital camera also has the potential to be used for landslide mapping and monitoring. In this study, a low cost digital camera has been used to acquire digital images of a simulated model build from sand and cement (dimension of 1m × 3m) which represent some form of topographic surface. In the simulated model, an area was excavated to simulate landslide occur in the area. The acquired digital images of the simulated model were then processed using photogrammetric technique to the final photogrammetric output that is the digital orthophoto. The digital camera used is of high resolution and suitable for large scale mapping which does not involve large study area, require moderate accuracy and limited budget. The objective of this study is to investigate the capability of a low cost digital camera in generating three dimensional models, digital elevation model (DEM) and finally the digital orthophoto. The other objective of this study is to investigate whether the data captured using the digital camera can be used for volume determination that was excavated from an area in the simulated model. The results of the study showed that the low cost digital camera is capable of producing digital orthophoto and capable of determining the excavated volume of the simulated model.

Recently, Template matching approach has been widely used to locate faces with various pose, illumination and clutter background. Normalized Cross-correlation (NCC) is an effective and simple measurement method to compute the similarity matching between the stored faces templates and the rectangular blocks of the input image to locate the face position. However, localization error occurs very often due to some rectangular blocks which have more face than correct blocks because of the effect of matrices values of these blocks. In this paper we proposed a simple preprocessing method before the use of NCC. This is to reduce the effects of such problems by increasing the values of the input image pixels. The result showed a significant improvement in localization accuracy compared with the use of NCC alone which is only up to 11%. Yale University database was used to evaluate our proposed method.

This paper presents the performances of Proportional (P), proportional-integral (PI) and proportional-integral-derivative (PID) modes controller to control an automatic water level control system. This project is developed to verify the performance of water level control system using PID control modes. The measurements of water level control system were collected from process plant which is located at Process Laboratory, UiTM Pulau Pinang. The measurements that have been carried out were analyzed based on three modes controlled that are Proportional, Proportional-Integral and Proportional-Integral-Derivative. The response of each control mode has been determined to identify the time constant, rise time, peak time and percentage overshoot. The evaluation of the output has been carried out and compared by software simulation using MATLAB toolbox. The results indicate that measured data and simulated data were showing a similarity in the responses and time constant.

Recent research in the field of Human Computer Interaction aims at recognizing the user's emotional state in order to provide a smooth interface between humans and computers. This would make life easier and can be used in vast applications involving areas such as education, medicine etc. Human emotions can be recognized by several approaches such as gesture, facial images, physiological signals and neuro imaging methods. Most of the researchers have developed user dependent emotion recognition system and achieved maximum classification rate. Very few researchers have tried to develop a user independent system and obtained lower classification rate. Efficient emotion stimulus method, larger data samples and intelligent signal processing techniques are essential for improving the classification rate of the user independent system. In this paper, we present a review on emotion recognition using physiological signals. The various theories on emotion, emotion recognition methodology and the current advancements in emotion research are discussed in subsequent topics. This would provide an insight on the current state of research and its challenges on emotion recognition using physiological signals, so that research can be advanced to obtain better recognition.
