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 lightweight with the ability to produce a better measurement...
This paper presents an investigation of the reflectivity performance for hollow pyramidal shape microwave absorbers. The pyramidal absorbers used in this study is constructed using four 15cm-pyramidal absorbers stacked on each other to equal the height of one single 45cm-absorber. The wave frequency ranging from 8GHz to 12 GHz was chosen for simulation and measurement of the absorber performance....
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 finger contributes different resistance value of the bending...
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 during lecture session with real application. With the...
An anechoic chamber is considered good when there is no signal reflection inside the chamber and also when there is no incoming signal from outside the chamber. The key element inside an anechoic chamber is the absorbing material. The evaluations of mini anechoic chamber fitted with coated absorbers were carried out by analyzing the absorption performance. The study includes the comparison of measurement...
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 and also that it is laden with human error. Therefore,...
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 network to classify the breast cancer correctly between...
