Surface roughness (Ra) and kerf taper ratio (TR) characteristics of an abrasive water jet machined surfaces of glass/epoxy composite laminate were studied. Taguchi’s design of experiments and analysis of variance were used to determine the effect of machining parameters on Ra and TR. Hydraulic pressure and type of abrasive materials were consider

This paper describes the design, analysis and comparison of two ∞ H controllers that use two different uncertainty model representations; unstructured and structured (parametric) uncertainties. The later is usually considered as less conservative. However, the application of intelligent techniques like Adaptive Neural Fuzzy Inference System (ANFI

This research seeks to identify the ways in which land use planning system can be used to improve public health in Malaysia. the present state of Malaysian environment has been deteriorating owing to the priority accorded to economic development is rather worrying. This study seeks to examine the role assumed by the land planning and development pr

IFSB’s Guiding Principles on Shari'ah Governance Systems for Institutions Offering Islamic Financial Services defines “Shari'ah governance system” as the set of institutional and organisational arrangements through which an institution offering Islamic financial services oversees Shari'ah compliance, i.e., that Islamic banking pro

In this study, biodiesel was produced from sludge palm oil (SPO) using tolune-4-sulfonic monohydrate acid (PTSA) as an acid catalyst in different dosages in the presence of methanol to convert free fatty acid (FFA) to fatty acid methyl ester (FAME), followed by a transesterification process using an alkaline catalyst. In the first step, acid cataly

In this study sulphuric acid has been used in pre-treatment of sludge palm oil for biodiesel production by esterification process. The purpose of pre-treatment process was reducing the free fatty acids (FFA) content in the sludge palm oil (SPO) to a minimum level for biodiesel production. Esterification process of SPO was carried out to evaluate su

A reverse phase high performance liquid chromatographic method for the detection of the neurotransmitters namely serotonin, tryptophan and dopamine in human blood samples has been developed. Spiked standard samples were analysed using a fluorescence detector after chromatographic separation. For the analytes a working range of 2.5 ng/mL to 25 ng/mL

The reduction of free fatty acids (FFAs) in sludge palm oil (SPO) was measured at different sonication time from 30 to 300 min and the optimum time was determined. It is reasonable to indicate that the pretreatment of SPO by applying ultrasonic energy is related to long sonication time. The results showed that the FFA content of SPO reduced from 24

Computer generated speech replaces the conventional text based interaction methods. Initially, speech synthesis generated human voice that lacked emotional expression. This kind of speech does not encourage users to interact with computers. Emotional speech synthesis is one of the challenges of speech synthesize research. The quality of emotional s

Herbal or traditional remedies have been used to cure different ailments since pre- historic times. The use of recorded herbal medicines can be traced back to about 5000 years ago when the Sumerian's used plants such as thyme and laurel as a remedy for ailments. According to the WHO report at present about 70 to 80 percent of world population i
