Koh and Sea Sand as Green Catalyst for Biodiesel Production
Research Output | Dar Al-hikmah Library | IIUM Only

Many developed countries have focused on generating energy from the earth’s resources, which is a key input for human wellbeing, social growth, economic progress and higher living standards. Biodiesel is a clean-burning, easy-tomake diesel made from fats or oils. Biodiesel can be made from either vegetable oil or animal fats, and it works in any

Comparison Study on Mechanical Properties of 3d Printed Pla and Pla/aluminium Composites Using Fused Deposition Modeling Method
Research Output | Dar Al-hikmah Library | IIUM Only

3D printing technology has been developed to produce prototype and end used parts. The demand is increasing recently making this technology a popular choice for the industry especially using fused deposition modeling (FDM) method. A common material used for this FDM technology is polylactic acid (PLA) as it is sustainable, low cost, and compatible

A Short Review on the Effect of Nozzle Geometry in 3d Printing Process Using Fdm System
Research Output | Dar Al-hikmah Library | IIUM Only

Layer-by-layer buildup of material is utilized in the process known as additive manufacturing (AM) to produce prototypes or end products. Fused deposition modelling (FDM) is one of the most commonly used AM processes. For FDM, the extruder’s nozzle plays a significant role as it is responsible for creating the build of material layer by layer. Th

The Effects of Fdm Printing Parameters on the Compression Properties of Polymethylmethacrylate (Pmma) Using Finite Element Analysis
Research Output | Dar Al-hikmah Library | IIUM Only

3D printing technology has become a favored alternative in fabricating parts due to its flexibility in product customization. Recently, an abundant number of studies have been conducted to improve the overall quality of the 3D printed parts. One of the essential qualities is to provide mechanical properties that fulfill the functionality of the fin

A Review on Modes of Failure of Rail Track Structure in Railway Transportation
Research Output | Dar Al-hikmah Library | IIUM Only

The train is one of the main transportations to move or transfer loads, including people and goods from one place to another on wheeled vehicles running on a railways track. Since, the railways were exposed to extreme conditions, the purpose of the design structure for the railways is to overcome the circumstances. Furthermore, the same train runni

Analysis of high-Density Surface Electromyogram (hd-Semg) Signal for Thumb Posture Classification from Extrinsic Forearm Muscles
Research Output | Dar Al-hikmah Library | IIUM Only

For amputees, the development of cybernetic hands that closely resembles the functions of real hands is essential for comfortability and functionality purposes. Controlled by intrinsic and extrinsic muscles, human thumb plays a major role in differentiating hand gestures. For those who have lost their intrinsic hand muscles, any information about m

Family Disputes in Administration of Estates: Analysis on Mediation as Effective Dispute Resolution Mechanism in Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

A family dispute is one of the issues that occur in the administration of the deceased’s estate. Such dispute may happen at any stage in estate administration, ranging from the application of letters of representation until the distribution of the deceased’s asset. The occurrence of family dispute tends to affect the administration adversely an

The Roles of the Personal Representative in Estate Administration in Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

The administration of an estate refers to a process of managing and distributing the deceased’s estate to the beneficiaries which take effect after his death. The tasks to administer the estate are handled by the personal representative from the beginning until the end of the administration. Appointment of a capable personal representative is the

Optimal Piezoelectric Shunt Damper Using Enhanced Synthetic Inductor: Simulation and Experimental Validation
Research Output | Dar Al-hikmah Library | IIUM Only

Piezoelectric material has the ability to convert mechanical energy to electrical energy and vice versa, making it suitable for use as an actuator and sensor. When used as a controller in sensor mode, the piezoelectric transducer is connected to an external electrical circuit where the converted electrical energy will be dissipated through Joule he

Rain Attenuation at C, Ku and Ka Bands Determined Using Earthsatellite Link Beacon Signals in Tropical Region
Research Output | Dar Al-hikmah Library | IIUM Only

Spectrum congestion in frequencies below 10 GHz is pushing satellite network operators to migrate to higher bands. Nonetheless, availability and system performance can be seriously degraded at higher frequency bands when the operating link experiences severe rainfall intensity. A study has been carried out to investigate the different consequences
