Discontinuous Transmission and Multiplexing
Research Output | Dar Al-hikmah Library | IIUM Only

Discontinuous Transmission (DTX) is a concept used in some mobile standards, mostly in Groupe Special Mobile (GSM) systems. In DTX systems, Voice Activity Detection (VAD) and comfort noise are essential element. The usage of DTX in the systems allo\vs transmissions during activity periods and remains silent during non-activities. This chapter is de

Proximate Composition, Minerals Contents, Functional Properties of Mastura Variety Jackfruit (Artocarpus Heterophyllus) Seeds and Lethal Effects of its Crude Extract on Zebrafish (Danio Rerio) Embryos
Research Output | Dar Al-hikmah Library | IIUM Only

Jackfruit (Artocarpus heterophyllus) is a popular and valuable fruit in Malaysia. The present study aims to determine the proximate composition, mineral contents and functional properties of jackfruit seed powder (JSP) of Mastura cultivar and assess the toxicity of the jackfruit seed crude extract using embryonic zebrafish model. The proximate anal

Lack of Kudrat: a Physical Illness Experience of Young Malay Breast Cancer Patients
Research Output | Dar Al-hikmah Library | IIUM Only

This qualitative study aims at exploring the illness experiences of young Malay breast cancer patients in relation to the symptoms they suffered from. Thirteen young Malay breast cancer patients in Kuala Lumpur and several selected areas of Selangor were selected through purposive snowballing technique. In relation to this, an ethnographic fieldwor

Performance Evaluation on Error Probabilities of Coded Bpsk System Using the Linear (23, 12) Golay Code with hard-Decision Decoding
Research Output | Dar Al-hikmah Library | IIUM Only

Channel impairment due to the existence of noise and interference is a major problem in the communication system. To combat this problem, channel coding technique is often used. In this paper, Bit Error Rate (BER) performance is evaluated by a simulation in a MATLAB program using the linear (23,12) Golay Code with coded BPSK system for the fading c

Alkaloids from Popowia Perakensis and their Dipeptidyl Peptidase Iv(Dpp Iv) Inhibitors
Research Output | Dar Al-hikmah Library | IIUM Only

A study on the alkaloidal composition on the Malaysian Annonaceae species, i.e Popowia perakensis King has been carried out. Barks of Popowia perakensis were extracted with hexane, dichloromethane and methanol, respectively. Dichloromethane extract further underwent the acid base treatment to give the alkaloidal crude extract. Isolation of compound

Wireless Connectivity Predicaments in gsm-Based Amr System : an Empirical Research
Research Output | Dar Al-hikmah Library | IIUM Only

The convergence of Global System for Mobile Communication (GSM) and Information Communication Technology (ICT) allows the mobile and wireless application to be implemented in Automatic Meter Reading (AMR) system. In addition to the advancement of cellular technology and spectrum refarming, GSM-based AMR system is continuously facing propagation cha

Aerodynamics of a Circular Planform Wing
Research Output | Dar Al-hikmah Library | IIUM Only

This paper investigates the aerodynamics of a circular plan form wing at high Reynolds numbers numerically. Commercial software STAR-CCM+ has been used for the study. The numerical results were presented in terms of flow visualization, pressure over the wing, velocity contour and streamlines, lift and drag coefficients for angle of attacks ranging

A Case Study on Vocabulary Learning Strategies in Malaysia: Implications for Teaching and Learning
Research Output | Dar Al-hikmah Library | IIUM Only

Within the context of learning English for specific purposes (ESP), vocabulary acquisition plays a crucial role in the development of written and spoken communication in both technical and non-technical industries. Thus, the use of vocabulary learning strategies would determine both learners' fluency as well as confidence in communicating. This

Fake News, Media Credibility and Trust on Institutions
Research Output | Dar Al-hikmah Library | IIUM Only

Community leaders often speak about the merits and significance of Trust as Trust is deemed fundamental to the workings of institutions in society. Trust is researched in management, politics, sociology, communication and in other subjects but the underlying reasons for the lack of trust are still far from satisfactory.
