Experimental Study on Potential Use of Photochromic Thin Film as Energy Harvester
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents the application of design of experiments (DOE) in the characterization of the photochromic thin film after irradiation to UV light and designing of a circuit as a potential energy harvester. The results from this study suggest that exposure time at high level and interaction between exposure time and thickness of thin film have

A Framework for non-Contact ECG Signal Detection Device on Smart Chair and its Implementation
Research Output | Dar Al-hikmah Library | IIUM Only

Heart disease is the top cause of death in Malaysia. Arrhythmia is a sign of heart diseases that entails abnormal heart rhythm and is detected mostly by electrocardiogram (ECG) devices, which are attached to the chest, arms or legs of an individual. This mostly requires contact with the skin, which has to be routinely examined. Unfortunately, in un

A Numerical Investigation of Explicit pressure-Correction Projection Methods for Incompressible Flows
Research Output | Dar Al-hikmah Library | IIUM Only

A numerical investigation is performed on an explicit pressure-correction projection method. The schemes are fully explicit in time in the framework of the finite difference method. They are tested on benchmark cases of a lid-driven cavity flow, flow past a cylinder and flow over a backward facing step. Comparisons of the numerical simulations have

Mobile Agent Based multi-Layer Security Framework for Cloud Data Centers
Research Output | Dar Al-hikmah Library | IIUM Only

Objective:This paper proposes a new mobile agent based cloud security framework comprising four different security and authentication layers to establish the trust relationship between two entities before using cloud services. Methods/Analysis:The proposed framework is divided into four layers with each performing authentication, verification and i

Aerodynamics and Static Stability Characteristics of a Hybrid Buoyant Aerial Vehicle at Low Speed
Research Output | Dar Al-hikmah Library | IIUM Only

It is well known that a big aviation market in the world is air transport of passengers and goods and buoyant aerial vehicles are one of the potential candidates for such applications. Aerodynamic and stability characteristics of such vehicles are critical issues of design and any new such design should exhibit longitudinal and directional stabilit

The Notion of Place, Place Meaning and Identity in Urban Regeneration
Research Output | Dar Al-hikmah Library | IIUM Only

Urban regeneration within traditional settings has transformed places and constructed meanings embedded in the existing social and cultural settings. Thus, the social and emotional meanings, attached to or evoked by the elements of the urban environment were at least as important, often more so than the structural and the physical aspects of people

power-Off Static Stability Analysis of a Clean Configuration of a Hybrid Buoyant Aircraft
Research Output | Dar Al-hikmah Library | IIUM Only

In the present study, the static stability of a hybrid buoyant aircraft is estimated using a panel method to solve the potential flow about the aircraft’s components other than the voluminous fuselage. A viscous flow solver was used to compute the flow over the fuselage to obtain the stability coefficients. A combination of the results of the two

Sense of well-Being Indicators: Attachment to Public Parks in Putrajaya, Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

In Malaysian urban areas, the issue of underutilization of public parks persists despite the apparently well-designed landscape. Face to face interviews with 30 park users in SaujanaHijau Park (SP) and Putra Perdana Park (PP) in Putrajaya were conducted to examine the role of place attachment in park utilization and social interaction. The study fo

Place Attachment and the Value of Place in the Life of the Users
Research Output | Dar Al-hikmah Library | IIUM Only

Place attachment is a form of connection between a person and the environmental setting. In the production of urban places, planners and designers mainly focus on the quality of the physical components. However, the aspects of meanings and attachment are not adequately considered in the planning and decision-making process. This study utilizes semi

The Hamiltonian three-Parameter Spaces of the Q -state Potts Model with Three Competing Interactions on a Cayley Tree
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper, we study the phase diagrams for the integer q-state (q ≥ 3) Potts model on a Cayley tree for order two with competing nearest-neighbor interactions J 1, prolonged next-nearestneighbor interactions J p and two-level triple-neighbor interactions J t . The exact phase diagrams of the Potts model with some competing interactions on a C
