real-Time Malaysian Sign Language Translation Using Colour Segmentation and Neural Network
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper we present an automatic visual-based sign language translation system. Our proposed automatic sign-language translator provides a real-time English translation of the Malaysia SL. To date, there have been studies on sign language recognition based on visual approach (video camera). However, the emphasis on these works is limited to a

Automatic Diagnosis of Diabetic Retinopathy from Fundus Images Using Digital Signal and Image Processing Techniques
Research Output | Dar Al-hikmah Library | IIUM Only

Automatic diagnosis and display of diabetic retinopathy from images of retina using the techniques of digital signal and image processing is presented in this paper. The acquired images undergo pre-processing to equalize uneven illumination associated with the acquired fundus images. This stage also removes noise present in the image. Segmentation

Robust Autopilot Design with Maximum Stability Radius
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents the robust control design for aircraft autopilot. The controller provides a maximum stability radius to the closed-loop system. The technique uses the notion of complex stability radius and the Linear Matrix Inequalities (LMI) to obtain the feedback controller gain. The technique is illustrated on a feedback controller of an aut

A New Method of Correcting Uneven Illumination Problem in Fundus Images
Research Output | Dar Al-hikmah Library | IIUM Only

Recent advancements in signal and image processing have reduced the time of diagnoses, effort and pressure on the screeners by providing auto diagnostic tools for different diseases. The success rate of these tools greatly depend on the quality of acquired images. Bad image quality can significantly reduce the specificity and the sensitivity which

Production of a Panel of Monoclonal Antibodies Against the Nucleocapsid Protein of Heat Resistant Newcastle Disease Virus
Research Output | Dar Al-hikmah Library | IIUM Only

A panel of six monoclonal antibodies against the nucleocapsid protein (NP) of Newcastle disease virus (NDV) strain AF2240 was produced by immunization of Balb/c mice with purified NP. Isotyping test revealed three of the monoclonal (mAbs) were IgG1 and the others were IgG2a. All of the mAbs recognized linearized NP epitopes. The reactivity of these

Optimization of Operating Conditions of Rotary Drum Bioreactor for Lignin Peroxidise Production by Solid State
Research Output | Dar Al-hikmah Library | IIUM Only

Solid state bioconversion of empty fruit bunches (EFB) for lignin peroxidase (LiP) by Phanerocheate chrysosporium through optimum operating conditions of a rotary drum bioreactor (RDB) was investigated. The study was carried out in the 50L of RDB fabricated locally for 6 days of treatment. The process conditions such as initial pH of 5.5, inoculum

Effectiveness of Cryogenic Machining with Modified Tool Holder
Research Output | Dar Al-hikmah Library | IIUM Only

The present study involves two processes; modification of the tool holder for use with cryogenic cooling system, and implementation of the new design and testing its effect on tool life and product quality. Liquid nitrogen, which is the most suitable fluid for cryogenic machining is used in this work. Two different flow outlets were tested for this

The Protective Effect of Hibiscus Sabdariffa Towards Liver Toxicity
Research Output | Dar Al-hikmah Library | IIUM Only

This study was carried out to investigate the effect of Hibiscus sabdariffa or roselle on the progression of acute liver injury in rats. The liver injury was induced by administration of 1000 mg/kg acetaminophen intraperitoneally and aqueous extract at low (500 mg/kg) and high (1000 mg/kg) doses of H. sabdariffa was given to rats by force feeding.

Building Consumers’ Confidence in Adopting e-Commerce: a Malaysian Case
Research Output | Dar Al-hikmah Library | IIUM Only

Consumers’ confidence on the online transactions is vital for the continuous growth and development of electronic commerce. In the present study, we experimentally investigate the measures of consumers’ perceived security and privacy over online transactions as well as the perceived trust and reliability of online vendors in order to influence

Mechanical and Fracture Toughness Behavior of Tpnr Nanocomposites
Research Output | Dar Al-hikmah Library | IIUM Only

Thermoplastic natural rubber (TPNR) nanocomposites containing organophilic layered silicates were prepared by melt blending method at 180 �C using internal mixer (Haake 600P). The aim of this study is to determine the influence of the organoclay filler on the mechanical and fracture properties. In this study, two mixing methods were employed to i
