The Impact of Randomness on High Speed Wireless Campus Network in Ieee802.11e
Research Output | Dar Al-hikmah Library | IIUM Only

The enhancement of channel access mechanism assures to provide Quality of Service (QoS) using the service differentiation mechanism over WLAN in IEEE802.11e. The service differentiation scheme is used in the Enhanced Distributed Channel Access (EDCA) MAC layer protocol and this protocol is used the random back-off window algorithm to provide QoS fo

Isolation and Characterization of Antithrombin Peptides from the Saliva of Malaysian Leeches
Research Output | Dar Al-hikmah Library | IIUM Only

Purpose: To isolate and characterize the antithrombin compounds of Malaysian leeches’ saliva collection (LSC) for use as anticoagulant proteins and peptides. Method: Reversed phase - high performance liquid chromatography (RP-HPLC) was used to isolate all proteins from LSC. All isolated proteins were tested for anticoagulant activity by applying

key-Dependent s-Box in Lightweight Block Ciphers
Research Output | Dar Al-hikmah Library | IIUM Only

This paper introduces new methods of how to generate a suitable key-dependent substitution boxes (Sboxes) for use in lightweight block ciphers. An S-box is commonly used in block ciphers to provide the crucial property of nonlinearity. And one of the advantages of using key-dependent S-boxes is that it is difficult for an attacker to perform attack

Effect of Dewatering Aid Dosage in Electroforced Sedimentation
Research Output | Dar Al-hikmah Library | IIUM Only

Nowadays wastewater treatment plants are producing huge amount of sludge. The water content of the traditionally dewatered sludge, resulting from drying beds, centrifuges, vacuum filters, screw press filters and pressure filters, remains a critical factor affecting the choice of transportation vehicles, transportation costs, and suitability of slud

Highly Cytotoxic Agents from Luvunga Scandens Against Human Breast Adenocarcinoma Cell Line (Mcf7)
Research Output | Dar Al-hikmah Library | IIUM Only

Breast cancer is among of the frequently diagnosed cancer and major of death in the most of country in the world. These led to the necessity for the development of potential chemotherapeutic agents against breast cancer cells with novel mechanisms of actions. The plant-derived triterpeniods commonly used due to its ability to exhibit cytotoxicity a

Novel Packet Scheduling Algorithm Based on Cross Component Carrier in lte-Advanced Network with Carrier Aggregation
Research Output | Dar Al-hikmah Library | IIUM Only

LTE-Advanced provides considerably higher data rates than the early releases of LTE. The carrier aggregation CA) technology allows scalable expansion of effective bandwidth provided to user equipment (UE) through simultaneous utilization of radio resources across multiple carriers. In this paper we propose a new packet scheduling (PS) criterion alg

Bioimpedance Spectroscopy System for Characterization of Cancer Cells
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents a design for a Bioimpedance spectroscopy system on an FPGA board for characterization of cancer cells. The proposed hardware uses a digital auto balance bridge implemented in Verilog. Using an FPGA allows the system to be designed to have a multichannel signal acquisition from two or more sources, and to be smaller than commerci

Challenges in non-Point Source Pollution — Sampling and Testing
Research Output | Dar Al-hikmah Library | IIUM Only

Point pollution sources are usually noticeable, confined and the pollution loads are relatively easy to estimate. Therefore, the treatment technologies can be easily applied to abate pollution from the point sources (PS). On the contrary, non-pointsource (NPS)pollution is generated due to precipitation process, and it is usually difficult to estima

Adsorption of Chlorine from Drinking Water by Granular Activated Carbon
Research Output | Dar Al-hikmah Library | IIUM Only

The effects of GAC dosage, contact time, agitation speed and the initial concentration of free chlorine were investigated at the room temperature ranges between 23-27˚C with a constant pH of 7.0±0.10. The statistical optimization of the experimental condition was carried out using Central Composite Design (CCD) to develop the regression models fo

Olbca: a New Lightweight Block Cipher Algorithm
Research Output | Dar Al-hikmah Library | IIUM Only

Lightweight block cipher algorithms are vital for constrained environment. It is easy to propose an algorithm that optimize any two factors like (security and cost), (security and performance) and (cost and performance) but it is difficult to optimize three factors together at the same time. In this paper, we propose a new lightweight block cipher
