A Comparison of Energy Absorbing Capabilities of Paper and Steel Structures Subjected to Progressive Failure Under Free Falling Objects
Research Output | Dar Al-hikmah Library | IIUM Only

An inverted paper cup of 0.26 mm thickness was subjected to deformation under a freely falling steel ball at a velocity of 2.77 m/sec. The deformed features of the paper cup were measured. The dynamic loading event was simulated using piecewise linear plasticity material model in LSDYNA. Deformed shape of the paper cup in finite element model match

Energy and Thermodynamic Performance of Refrigerator Using Pure Hydrocarbon and Mixture of Hydrocarbons as Refrigerants
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents an experimental investigation on the performance of a domestic refrigerator using pure butane and mixture of propane, butane and isobutene as refrigerants. The experiment was conducted with a refrigerator designed to work with HFC-134a under the same no load condition at a surrounding temperature of 25°C and 28°C. The refriger

Development of gis-Based Traffic Simulation on the Jakarta’s Highway
Research Output | Dar Al-hikmah Library | IIUM Only

One serious problem in Jakarta megacity is the daily traffic jam. Recently, according to the ever increasing amount of newly registered vehicles in Jakarta, the time interval needed to across some districts in Jakarta tends to be longer. The main reason for the traffic jam is the condition in which the road capacity and the arrival rate of vehicles

Modified Pet / Spect Cylindrical Phantom
Research Output | Dar Al-hikmah Library | IIUM Only

It is mandatory to assess / evaluate performance parameters of all medical imaging systems employed in diagnostic imaging modalities before their use in patient studies. For such evaluations a number of commercially available test phantoms exist, e.g., in nuclear medicine tomography - PET/SPECT phantoms. A cylindrical PET/SPECT phantom (R A Carlson

Antioxidant Properties of Methanolic and Ethanolic Extracts of Malaysian Aromatic Plants’ Leaves: a Comparative Study
Research Output | Dar Al-hikmah Library | IIUM Only

This study was done to determine the antioxidant properties of methanolic and ethanolic extracts of four Malaysian aromatic plants’ leaves, namely knotweed (Polygonum minus), curry (Murraya koenigii), kaffir lime (Citrus hysrix) and fragrant screwpine (Pandanus odorus). Total phenolic content (TPC) assay using Folin-Ciocalteu method was used to a

Desirable Airfoil Features for smaller-Capacity straight-Bladed Vawt
Research Output | Dar Al-hikmah Library | IIUM Only

In the small scale wind turbine market, the simple straight-bladed Darriues types vertical axis wind turbine (SB-VAWT) is very attractive for its simple blade design. A detailed aerodynamic performance analysis of the main aerodynamic challenges of this type of wind turbine were first discussed and subsequently the authors conducted further literat

Design of a special-Purpose Airfoil for smaller-Capacity straight-Bladed Vawt
Research Output | Dar Al-hikmah Library | IIUM Only

Selection of airfoil is one of the most critical factors in achieving better aerodynamic performance and in determining the optimum dimensions of a fixed-pitch straight-bladed Darrieus type vertical axis wind turbine (SB-VAWT), along with solidity, radial arm parasitic drag, aspect ratio etc. Airfoil related design changes also have the potential f

Pediatric Auricular Chondrocytes Gene Expression Analysis in Monolayer Culture and Engineered Elastic Cartilage
Research Output | Dar Al-hikmah Library | IIUM Only

Objectives: This study was aimed at regenerating autologous elastic cartilage for future use in pediatric ear reconstruction surgery. Specific attentions were to characterize pediatric auricular chondrocyte growth in a combination culture medium and to assess the possibility of elastic cartilage regeneration using human fibrin. Study design: Labora

Application of Response Surface Methodology Coupled with Genetic Algorithm in the Optimization of Cutting Conditions for Surface Roughness in end-Milling of Inconel 718 Using Coated wc-Co Inserts
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents an efficient method of optimisation of surface roughness in end milling of Inconel 718 using TiAlN coated inserts under dry conditions by coupling response surface methodology (RSM) with genetic algorithm (GA). RSM has been utilized to develop an efficient mathematical model for surface roughness in terms of cutting parameters.

Encryption in Tecb Mode: Modeling, Simulation and Synthesis
Research Output | Dar Al-hikmah Library | IIUM Only

The growth of the Internet as a vehicle for secure communication has resulted in Data Encryption Standard DES) no longer capable of providing high-level security for data protection. Triple Data Encryption Standard (3DES) is a symmetric block cipher with 192 bits key proposed to further enhance DES. Many applications crave for the speed of a hardwa
