Article
Agriculture waste has huge potential to be used as an alternative material for constructing microwave absorber which is typically used in an anechoic chamber. The existing microwave absorbers are normally manufactured from chemical substances. This project is proposing the use of a new composite biomass material namely coconut coir, for constructin...

This paper shows findings of the application of Particle Swarm Optimization (PSO) algorithm in optimizing an Artificial Neural Network that could categorize between ripeness and unripeness stage of citrus suhuensis. The algorithm would adjust the network connections weights and adapt its values during training for best results at the output. Initia...
Article
Some of the already available prosthetic hands in the market are operated in open loop, without any feedback and expensive. This system counters those by having the prosthetic hand printed using 3D printer and consist of a feedback sensor to make it a closed loop system. The system generally consists of two sections, mainly Finger Input and Prosthe...
Article
Radiation Absorbing Material (RAM) is used to absorb radiations of electromagnetic wave surrounding us. Thus, the multiple layers’ microwave absorber using biomass composite materials could be one of the solutions to address the problem. In order to effectively absorb the radiation of electromagnetic wave, the multiple layers’ absorber is character...
Article
This paper presents a real-time and non-destructive method for capturing finger hand movement via a hand glove. From previous research, a major limitation appears to be limited portability due to presence of cloth support and less accuracy due to poor calibration (a tedious, non-automatic process). The proposed finger hand movement capturing system...
Conference Paper
In this paper, an adjustable angle sensor based on rotary potentiometer for measuring and monitoring finger flexion is proposed. Most of the current system is unadjustable, inaccurate, costly and hard to calibrate. The proposed system in this study consists of a rotary potentiometers and adjustable case, which makes it adjustable, compact and light...

This paper investigates the capacitance regression modelling performance of latex for various rubber tree clones, namely clone 2002, 2008, 2014 and 3001. Conventionally, the rubber tree clones identification are based on observation towards tree features such as shape of leaf, trunk, branching habit and pattern of seeds texture. The former method r...
Article
Communication is one of human basic necessity. People with disabilities usually use sign language to communicate with others. The study identifies the alphabet letters from the finger spelling based on American Sign Language (ASL) standard. The bending sensors were attached to three fingers of spelling glove where the bending movement of each finge...
Article
A virtual laboratory experiment has gradually growing on demand as preferable technical exposure method in many universities. This is due to time, facilities, cost and location limitation. This study focuses on the architecture, performance and effectiveness of a web-based laboratory in assisting students to relate theoretical knowledge learnt duri...
Article
In recent years, absorbing material has received great attention for various applications in electromagnetic wave, communications, radar, satellite systems, and anechoic chambers for the usage of both civil and military fields. This paper investigates the effectiveness of coconut shell-based microwave absorbing material. The absorber was prepared u...
Conference Paper
In dentistry, often dental radiography is related to teeth occlusal surface, which can be used for diagnostic and treatment purposes. Nonetheless the exposure of X-Ray dose may limit the usage of this technique. This paper presents the image construction from the occlusal surface of human teeth. The principle of the surface construction is from the...
Conference Paper

This paper presents a comparison study of two different MLP transfer functions for three different classification cases of breast cancer, thyroid disease and weather classification. The transfer functions under investigation are sigmoid and hyperbolic tangent. In the study, MLP network was trained and tested to investigate the ability of the networ...
Conference Paper

Cervical cancer been known to be the cause of many deaths each year. Screening tests, such as the Pap smear test used for the detection of the precancerous stage are able to avoid the occurrence of cervical cancer. However, the Pap smear test does have some disappointing disadvantages such as the fact that it has less effective slide preparation an...
Article
Control System Theory is a compulsory subject to be taken by engineering students in various disciplines. However to relate the theoretical knowledge with the real control system application is very challenging in a conventional faced to faced pedagogy due to the time, facilities, cost and location constraint. This paper discusses the design and im...
