In this paper, a novel design of 8 Gbps impulse radio ultra wideband (IR-UWB) pulse generator for short distances wireless communication is presented. The proposed pulse generator is based on 250 ps pulses, which gives advantages in pulse generation and detection error reduction. The generated pulses satisfy the regulations of UWB Federal Communica

The purpose of this paper is to present the concept, development and the implementation of Islamic Management Standards in Malaysia Education Institutions particularly by the universities and community colleges. The experience from their implementations of the standards is described. This paper tried t highlight the implementation of the Islamic Ma

This study was carried out to isolate the active antibacterial compounds from marine sponge Neopetrosiaexigua. Using disc diffusion method, methanol extract of N. exigua showed a significantantibacterial activity. Sequentially, liquid-liquid extraction was performed using different polarity solvents ( n-hexane, carbon tetrachloride, dichloromethane

This study was carried out to isolate the active antibacterial compounds from marine sponge Neopetrosiaexigua. Using disc diffusion methodm methanol extract of N. exigua showed significant antibacterial activity (The inhibition zone against Staphylococcus aureus was 19.5 mm). sequesntially, liquid-liquid extraction was performed using solvenants wi

The purpose of this study is to attempt to clarify the importance of science of logic in Al-Farabi conception and its elation to the tertiary education, and to come out with method that should be employed in teaching logic. I will also explain the applicability of these methods. This may encourage students to see its importance in their education.

The questions “what is revelation?”, what does revelation tell us and what are its implications on man ?” are important questions for which we are still seeking answers even today. Does revelation give us knowledge that we cannot obtain by ourselves but once we hear it we can understand why it is true because there is some reasoning behind it

Uptake of the non-essential element, lead (Pb), by 7-days-old Arabidopsis thaliana seedlings caused inhibition of root growth. Pb accumulated mainly in the root and only a small proportion of the total uptake was transported to the shoot. At the ultrastructural level, Pb was localized mainly in the cell walls, intercellular spaces and vacuoles, whi

Problem statement: Chip shape and size varied widely in machining operations. Undesirable chip formation had a detrimental effect on surface finish, work-piece accuracy, chatter and tool life. Approach: This study included the findings of an experimental study on the instabilities of the chip formation and development of a mathematical model based

The intent of this paper is to review some timestampbased password authentication schemes using smart cards which have similar working principles. Many of the proposed timestampbased password authentication schemes were subsequently found to be insecure. Here, we investigate three schemes with similar working principles, show that they are vulnerab

A new technique was developed for the investigation of chatter formation considering the instability of the closed-loop system formed by machine tool structure and metal-cutting process. Machine tool structure indicates the importance of different system components and it’s dominating mode frequencies whereas the metal cutting process indicates t
