preload-Based starling-Like Control for Rotary Blood Pumps: Numerical Comparison with Pulsatility Control and Constant Speed Operation
Research Output | Dar Al-hikmah Library | IIUM Only

In this study, we evaluate a preload-based Starling-like controller for implantable rotary blood pumps (IRBPs) using left ventricular end-diastolic pressure (PLVED) as the feedback variable. Simulations are conducted using a validated mathematical model. The controller emulates the response of the natural left ventricle (LV) to changes in PLVED. We

Adaptive Fault Tolerant Checkpointing Algorithm for Cluster Based Mobile Ad Hoc Networks
Research Output | Dar Al-hikmah Library | IIUM Only

Mobile Ad hoc NETwork (MANET) is a type of wireless network consisting of a set of self-configured mobile hosts that can communicate with each other using wireless links without the assistance of any fixed infrastructure. This has made possible to create a distributed mobile computing application and has also brought several new challenges in distr

Identification of Incomplete Contract Provision in Pfi Contract in Asean Countries: a Case Study on Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

Recently, ASEAN countries had called for a more enhanced infrastructure investment to cater the rising economic and social growth in the region. Private Finance Initiative (PFI) has been adopted by many to serve the purpose. However, there is lack of standard procedure for PFI implementation among the ASEAN countries. Every country adopted their ow

A New Efficient Checkpointing Algorithm for Distributed Mobile Computing
Research Output | Dar Al-hikmah Library | IIUM Only

Mobile networks have been quickly adopted by many companies and individuals. However, multiple factors such as mobility and limited resources often constrain availability and thus cause instability of the wireless environment. Such instability poses serious challenge for fault tolerant distributed mobile applications. Therefore, the classical check

A non-Blocking Coordinated Checkpointing Algorithm for message-Passing Systems
Research Output | Dar Al-hikmah Library | IIUM Only

This paper proposes an efficient non-blocking coordinated checkpointing algorithm for distributed message passing system which uses transitive dependency information. The processes synchronize their checkpointing activities so that a globally consistent set of checkpoints is always maintained in the system. These algorithms do not require channels

Incomplete Contract in Private Finance Initiative (Pfi)contracts: Causes, Implications and Strategies
Research Output | Dar Al-hikmah Library | IIUM Only

An incomplete contract is a contract that fails to state all the parties’ rights and obligations, has gaps, missing provisions, and ambiguities in its terms and conditions. In theory, complete contracts cannot be achieved, and many contracts inevitably remained incomplete. This also applies to Private Finance Initiative (PFI) contracts. Human fac

Applying Frbr Model to Bibliographic Works on al-Quran
Research Output | Dar Al-hikmah Library | IIUM Only

This study explores the feasibility of applying the object-oriented Functional Requirements for Bibliographic Records (FRBR) model to MARC-based bibliographic records on the Al-Quran. Based on the content analysis of 127 MARC-based bibliographic records on Al-Quran from the International Islamic University Malaysia (IIUM) OPAC system, this paper re

Residents’ self-Perceived Health and its Relationships with Urban Neighborhood Green Infrastructure
Research Output | Dar Al-hikmah Library | IIUM Only

Research has established that being in green elements in the landscape affect health and well-being. This paper presents the findings whether neighborhood green infrastructure (GI) in a community’s living environment is an underlying mechanism for urban residents’ self-perceived health. To study this, we seek residents’ participations through

Vertical Greenery as Public Art: the Public’s Perspectives
Research Output | Dar Al-hikmah Library | IIUM Only

VG is greenery where plants can be grown on, up, or against internal or external walls of buildings or as freestanding structures. PA is a structure or form that contains an artistic expression. It is placed in a freely accessible public space for people to view. VG has gained tremendous popularity in recent years, and this offers an opportunity to

Key Revocation in Wireless Sensor Networks: a Survey on a less-Addressed yet Vital Issue
Research Output | Dar Al-hikmah Library | IIUM Only

Key management in wireless sensor network (WSN) includes two important aspects namely key distribution, which constitutes the task of distributing secret keys to nodes in the network, and key revocation, which refers to the task of securely withdrawing the key information relating to any compromised node or because of tactical reasons. While in the
