Investigation of Three Dimensional Empirical Indoor Path Loss Models for Femtocell Networks
Research Output | Dar Al-hikmah Library | IIUM Only

Femtocell which is a home access point that installed by end consumers inside their houses is an important parameter and a promising technology in future wireless networks. It was proposed as a solution to the indoor propagation problems and to increase the indoor bandwidth. However, many challenges need to be addressed before deployment of femtoce

Comparison of Empirical Indoor Propagation Models for 4g Wireless Networks at 2.6 GHZ
Research Output | Dar Al-hikmah Library | IIUM Only

Indoor path loss models are playing an important role in the design and planning of the 4th generation of the mobile networks. Moreover, it is an important component of system level simulators used to evaluate and test the network performance before it has been established. Many propagation models were proposed for this purpose. Most of these model

s-Band Multiwavelength Brillouin/raman Distributed Bragg Reflector Fiber Lasers
Research Output | Dar Al-hikmah Library | IIUM Only

A multiwavelength Brillouin/Raman distributed Bragg reflector fiber laser operating in the S-band region is proposed and demonstrated. The laser uses a 7.7 km long dispersion-shifted fiber with an effective mode area of 15 μm2 as the Brillouin and Raman gain media simultaneously. Two 1420 nm laser diodes with a combined power of 372 mW are used as

Extraction of a Single Stokes Line from a Brillouin Fibre Laser Using a Silicon Oxynitride Microring Filter
Research Output | Dar Al-hikmah Library | IIUM Only

Extraction of a single channel Brillouin Stokes line generated by pumping a length of single mode fibre is demonstrated using a silicon oxynitride microring resonator. The high Q-factor microring resonator has a steep slope transmission profile with an extinction ratio of 20 dB and a free spectral range of 0.4 nm. Experimental results show that ext

Islamic Environmental Ethics and Green Technology Practices for Park Design: Potential of the Adaptation in Taman Tasik Titiwangsa
Research Output | Dar Al-hikmah Library | IIUM Only

Current global environmental problems such as global warming, urban heat island impact, water contamination and deforestation lead towards a great challenge to present and future generation in providing its solution. The role of design intervention in minimizing and mitigating such problems seems to be vital. Therefore, developing an environmental

محددات الشخصية الإبداعية عند الإمام الشافعي = the Determinants of Personal Creativity of Imam al-Shafii
Research Output | Dar Al-hikmah Library | IIUM Only

يهدف هذا البحث إلى دراسة محددات الشخصية الإبداعية عند الإمام محمد بن إدريس الشافعي، وذلك من خلال فحص أهم جوانب حياة هذا الإمام التي ساهمت مجتمعة في صقل شخصيته الإبداعية التي أثمرت صياغة رصينة

vision-Based Hand Posture Detection and Recognition for Sign Language - a Study
Research Output | Dar Al-hikmah Library | IIUM Only

Unlike general gestures, Sign Languages (SLs) are highly structured so that it provides an appealing test bed for understanding more general principles for hand shape, location and motion trajectory. Hand posture shape in other words static gestures detection and recognition is crucial in SLs and plays an important role within the duration of the m

Fighting Cyberterrorism with Legislative Bullet: are We Really Ready?
Research Output | Dar Al-hikmah Library | IIUM Only

National governments around the world have taken legislative steps to provide for stronger measures for fear of being struck by cyber-terrorists. Malaysia is not excluded. This paper examines the nature, scope of cyberterrorism and how it threatens the critical information infrastructure and national security. A brief survey is presented on cyberte

Modeling of Human Upper Body for Sign Language Recognition
Research Output | Dar Al-hikmah Library | IIUM Only

Sign Language Recognition systems require not only the hand motion trajectory to be classified but also facial features, Human Upper Body (HUB) and hand position with respect to other HUB parts. Head, face, forehead, shoulders and chest are very crucial parts that can carry a lot of positioning information of hand gestures in gesture classification
