We present recent work on a dual probe system containing electromagnetic acoustic transducers (EMATs) generating and detecting surface ultrasonic waves, and a pulsed eddy current (PEC) probe. This system is able to detect and size surface and near-surface defects in electrically conducting samples by looking at changes in the detected signal for ea

This new technology is realized by Photo Resist Lithography and NiCo Electro Fine Forming Process, and enables the design of a small contact spring for applications requiring high density, high speed and high durability. The evaluation result proved the capability of Low Normal Force (0.10N-0.15N at 0.3mm) at contact point (5μm radius), durability

The use of maximum length sequence (MLS) stimuli to elicit an auditory brainstem response (ABR) has been limited, in part, by the observation that these stimuli reduce ABR wave amplitudes. This study recorded ABR waveforms from 14 normally hearing adults using MLS click stimuli (maximum stimulus rate = 250 clicks per second) at stimulus levels of 7

Phytochemical and bioactivity studies of the leaves of Melastoma malabathricum L. (Melastomataceae) have been investigated. The n-hexane extract yielded α-amyrin, patriscabatrine and auranamide, ethyl acetate extract gave quercetin and quercitrin, and methanol extract gave quercitrin and kaempferol-3-O-(2”,6”-di-O-p-trans-coumaroyl)glucoside.

The automated auditory brainstem response (AABR) is an important tool for detecting hearing impairment in newborns, but it is often hindered by unacceptably long test times. On average, it takes 3 to 5 minutes per infant to acquire sufficient data to determine if an AABR waveform is present or absent. The successful reduction of this average test t

This study was done in order to determine the presence of antioxidant and the level of antioxidant activity of garlic (Allium sativum) and shallot (Allium cepa). Garlic and shallot have been the most common ingredients in the preparation of Malaysian cuisines and it has been long-held belief that these two Allium species posses many medicinal prope

This work addresses the structural weaknesses that threaten to derail counterterrorism efforts by the Malaysian government. It also highlights the links between various pre-September 11 security issues in Southeast Asia and the terrorism threat facing Malaysia at present. The limitations of the current counterterrorism approach by the government ar

In the aircraft industry, manufacturers have to decide quickly whether an impacted sandwich needs repairing or not. Certain computation tools exist at present but they are very time-consuming and they also fail to perfectly model the physical phenomena involved in an impact. In a previous publication, the authors demonstrated the possibility of rep

This paper aims at exploring, discussing and analyzing some major issues in teaching creative thinking skills (CTS) based on IIUM experience.1 These issues are challenges encountering trainers and lectures in teaching (CTS), strategies to overcome these challenges, and future implications proposed to enhance the process. It is well recognized world
