Identification of Instabilities of the Chip Formation and It’s Prediction Model During End Milling of Medium Carbon Steel (S45c) New
Research Output | Dar Al-hikmah Library | IIUM Only

Problem statement: Chip shape and size varied widely in machining operations. Undesirable chip formation had a detrimental effect on surface finish, work-piece accuracy, chatter and tool life. Approach: This study included the findings of an experimental study on the instabilities of the chip formation and development of a mathematical model based

A Review and Cryptanalysis of Similar timestamp-Based Password Authentication Schemes Using Smart Cards New
Research Output | Dar Al-hikmah Library | IIUM Only

The intent of this paper is to review some timestampbased password authentication schemes using smart cards which have similar working principles. Many of the proposed timestampbased password authentication schemes were subsequently found to be insecure. Here, we investigate three schemes with similar working principles, show that they are vulnerab

A New Technique for the Investigation of Chatter Formation During End Milling of Medium Carbon Steel (Aisi 45) New
Research Output | Dar Al-hikmah Library | IIUM Only

A new technique was developed for the investigation of chatter formation considering the instability of the closed-loop system formed by machine tool structure and metal-cutting process. Machine tool structure indicates the importance of different system components and it’s dominating mode frequencies whereas the metal cutting process indicates t

Denial of Service in Wireless Sensor Networks: Issues and Challenges New
Research Output | Dar Al-hikmah Library | IIUM Only

Wireless Sensor Network (WSN), composed of a huge number of resource-constrained sensors can be used for a large number of securitysensitive applications. Regardless of the type of application, smooth collection and delivery of data from this type of network is one of the critical requirements. If the data supply process is hampered and thus the ex

رسالة الإمام الشافعي : بحث في دواعي التأليف (Risalah al-Imam al-Shafi'i : Bahth Fi Dawa'i al-Ta'lif) New
Research Output | Dar Al-hikmah Library | IIUM Only

المستخلص تهدف هذه الدراسة إلى بحث دواعي تأليف كتاب الرسالة للإمام محمد بن إدريس الشافعي. وقد وضعت الباحثة مجموعة فرضيات للبحث منها أن تأليف الرسالة كان بسبب طلب عبد الرحمن بن مهدي ومنها والرد �

Improving Performance of Mobile Ad Hoc Networks Using Efficient Tactical on Demand Distance Vector (Taodv) Routing Algorithm New
Research Output | Dar Al-hikmah Library | IIUM Only

Ad hoc network is a group of wireless mobile computers (or nodes), in which individual nodes cooperate by forwarding packets for each other to allow nodes to commu- nicate beyond direct wireless transmission range. Previous research in ad hoc networking has generally studied the routing problem in a non-adversarial setting by assuming a trusted env

Secured Knowledge Sharing and Creation Using Rbac Model for e-Village New
Research Output | Dar Al-hikmah Library | IIUM Only

This paper introduces a Role Based Access Control (RBAC) model for e-Village in creating and sharing knowledge in a secure way. This includes secure information about marketing to help the products become an innovation and highly valuable. As a case study, the Pasir Region, East Kalimantan, has the 100 families who moved were originally from Jepara

Design of Environmental Friendly Hybrid Electric Vehicle New
Research Output | Dar Al-hikmah Library | IIUM Only

Hybrid electric vehicles (HEVs) powered by electric machines and an internal combustion engine (ICE) are a promising mean of reducing emissions and fuel consumption without compromising vehicle functionality and driving performances. This paper presents the design of an environmental friendly hybrid car that feature the gasoline engine and batterie

The Competing Interactions on a Cayley tree-Like Lattice: Pentagonal Chandelier New
Research Output | Dar Al-hikmah Library | IIUM Only

Different types of lattice spin systems with competing interactions have rich and interesting phase diagrams. In this study we present some new results for such systems involving the Ising spin system (i.e. � = �1) using a generalization of the Cayley tree-like lattice approximation. We study the phase diagrams for the Ising model on a Cayley t

Comparison of Microwave Path Lengths Between Temperate and Tropical Region Based on Effects of Rain New
Research Output | Dar Al-hikmah Library | IIUM Only

Rain is a major source of attenuation for microwave propagation above 7 GHz. The problem of rain attenuation prediction has been studied along the years. In spite of the e®ort developed in di®erent parts of the world, there are yet some points to be clari¯ed. This problem is quite di±cult to be solved, mainly due to the complexity of rain struc
