Measuring the Pollutants in a System of Three Interconnecting Lakes by the Semianalytical Method
Research Output | Dar Al-hikmah Library | IIUM Only

Pollution has become an intense danger to our environment. The lake pollution model is formulated into the three-dimensional system of diﬀerential equations with three instances of input. In the present study, the new iterative method (NIM) was applied to the lake pollution model with three cases called impulse input, step input, and sinusoidal i

Comparative Analysis of Lqr and Robust Controller for Active Suspension
Research Output | Dar Al-hikmah Library | IIUM Only

This paper aims to investigate the performance of linear quadractic regulator (LQR), robust H∞ and passive controller for active suspension of the quarter car model. The presented approach is based on linear model well supported by computer-aided control systems design (CACSD) tool which yields faster control design approach. The linear active su

A Short Review on Electrochemical Exfoliation of Graphene and Graphene Quantum Dots
Research Output | Dar Al-hikmah Library | IIUM Only

The synthesis of graphene and graphene quantum dots (GQDs) employing various approaches with a range of precursors, chemicals, and parameters has been reported. Most of the top-down and bottom-up techniques employ strong and hazardous chemical environments, complicated and tedious procedures, are time-consuming, and often require special equipment.

Grass Waste Derived Cellulose Nanocrystals as Nanofiller in Polyvinyl Alcohol Composite Film for Packaging Application
Research Output | Dar Al-hikmah Library | IIUM Only

Cellulose nanocrystals (CNCs) have shown remarkable application prospects due to their outstanding chemical and physical properties. In this research, cellulose nanocrystals were isolated from grass waste using alkali, bleaching and acid hydrolysis treatments and further used as nanofiller in polyvinyl alcohol (PVA) films. The valorisation of the g

Zinc Based Semiconductors / Polymer Thin Films Junction for Photovoltaic Application
Research Output | Dar Al-hikmah Library | IIUM Only

Thin films of ZnO and ZnTe semiconductors were deposited on ITO conducting glass substrates by sputtering and electrodeposition techniques respectively. On the other hand thin films of ion conducting solid polymer electrolyte were prepared by solution cast technique. The polymer is a blend of 50 wt% polyethylene oxide and 50wt% chitosan. To provide

Research Output | Dar Al-hikmah Library | IIUM Only

The main objective of the Shariah is to provide a basis to govern all aspects of Muslim life socially, economically as well as politically. The ultimate goal of the Shariah is to be a blessing for mankind. This is the primary purpose for which the Prophet Muhammad (Saw) was sent to this world. There is also a common belief among all societies aroun

Bitcoin Adoption in Banking and Finance: the Critical Factors of its Implementation
Research Output | Dar Al-hikmah Library | IIUM Only

Bitcoin is a e-currency created by the computational result of blockchain technology. It is the world's first decentralized anonymous digital circulation which accepts online transactions without relying on any third-party institutions or government. Though, its technology is considered as one of the secure online ledgers with strong cryptograp

Cryptocurrency Adoption in e-Payment: Barrier of its Implementation
Research Output | Dar Al-hikmah Library | IIUM Only

Cryptocurrency is a type of cryptographic e-currency generated by the computational result of mathematical techniques throughout blockchain technology. It has bitcoin as the world's first decentralized anonymous digital currency which allows online transactions without relying on any third-party institutions or government. Though, its technolog

The Efficiency of Islamic Banks in the Southeast Asia (Sea) Region
Research Output | Dar Al-hikmah Library | IIUM Only

The Islamic banking sector has become a crucial part of the global banking industry. Despite the Islamic banking industry’s encouraging growth in the Southeast Asia (SEA) region, prior studies mostly focused on Islamic banks’ efficiency in the individual country. To fill the literature gap, this study aims to measure the efficiency and producti

Contributing Factors of Urban Heat Island- an Investigation on Surface Temperature of Ground Surface Materials in Three Plazas with Different Types of Landscape Settings : a Case Study of Plazas in Putrajaya
Research Output | Dar Al-hikmah Library | IIUM Only

Urban heat island (UHI) is a phenomenon where an urban area is significantly warmer than its surrounding rural area (VoogtandOke, 2003). During night time, more heat is being released causing a greater temperature difference between the city and countryside. The increment of the air temperature is from the modification of land surface due to urban
