Language Classes Generated by Tree Controlled Grammars with Bounded Nonterminal Complexity
Research Output | Dar Al-hikmah Library | IIUM Only

A tree controlled grammar is specified as a pair (G, G′) where G is a context-free grammar and G′ is a regular grammar. Its language consists of all terminal words with a derivation in G such that all levels of the corresponding derivation tree – except the last level – belong to L(G′). We define the nonterminal complexity Var(H) of H = (

Improving Performance of Mobile Ad Hoc Networks Using Efficient Tactical on Demand Distance Vector (Taodv) Routing Algorithm
Research Output | Dar Al-hikmah Library | IIUM Only

Ad hoc network is a group of wireless mobile computers (or nodes), in which individual nodes cooperate by forwarding packets for each other to allow nodes to commu- nicate beyond direct wireless transmission range. Previous research in ad hoc networking has generally studied the routing problem in a non-adversarial setting by assuming a trusted env

neuro-Fuzzy Identification of an Internal Combustion Engine
Research Output | Dar Al-hikmah Library | IIUM Only

Dynamic modeling and identification of an internal combustion engine (ICE) model is presented in this paper. Initially, an analytical model of an internal combustion engine simulated within SIMULINK environment is excited by pseudorandom binary sequence (PRBS) input. This random signals input is chosen to excite the dynamic behavior of the system o

Barriers to ICT Use in Science Teaching: a Comparative Analysis of Malaysian and Saudi Science Teachers
Research Output | Dar Al-hikmah Library | IIUM Only

Despite the efforts expended by the governments of Malaysia and Saudi Arabia to promote science teachers’ use of ICT in the classroom, the ICT uptake among these teachers remains slow and dismal. This article reports on a study undertaken to explore and understand the barriers that prevented science teachers in both countries from using ICT in th

Weighted Splicing Systems
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper we introduce a new variant of splicing systems, called weighted splicing systems, and establish some basic properties of language families generated by this type of splicing systems. We show that a simple extension of splicing systems with weights can increase the computational power of splicing systems with finite components.Weighted

Design and Development of Active Vibration Isolation System for Free Space Optics Communication
Research Output | Dar Al-hikmah Library | IIUM Only

Free Space Optics (FSO) communication is a technology widely used today. It involves transmission of data from a transmitter to a receiver. In order to achieve successful data transmission, a continuous alignment between the transmitter and receiver telescope is needed. Misalignment could happen due to many factors. Vibration at the transmitter or

Incidence of Palmaris Longus Agenesis in Second Year Medical Students of Iium, 2011/2012
Research Output | Dar Al-hikmah Library | IIUM Only

The palmaris longus (PL) is one of the most variable muscles of the human body. The individuals may have unilateral or bilateral absence of PL, varies with ethnicity, gender and side of the body. An understanding of its variations is useful as it is often used as tendon graft for reconstructive surgery because of its little functional use and short

Interactive Learning Paper Model of Inguinal Canal
Research Output | Dar Al-hikmah Library | IIUM Only

The inguinal region is one of the most complex anatomic areas of human body even though it has been the subject of great interest to anatomists and surgeons because of its clinical importance. The aims of the study are to: 1. provide a simplification and in-depth understanding of the complex and confusing inguinal canal anatomy. 2. incorporate time

Case Studies in Anatomy: Upper Limb
Research Output | Dar Al-hikmah Library | IIUM Only

Anatomy, as a part of the medical school curriculum, has always been recognized as an essential foundation for the clinical sciences. It forms a basis for the study of the normal structure for the subsequent study of surgery, medicine, pathology and the other clinical disciplines. In recent decades, despite the decrease in the number of hours stude

Improvement in Mechanical Properties of Reinforced Thermoplastic Elastomer Composite with Kenaf Bast Fibre
Research Output | Dar Al-hikmah Library | IIUM Only

This paper report on the development of thermoplastic elastomer composite reinforced with 20 vol.% kenaf fibre. Two types of impact modifier were blended with polypropylene (PP) namely; thermoplastic natural rubber (TPNR) and polypropylene/ethylene–propylene–diene–monomer (PP/EPDM). Both composites were produced via double melt blending metho
