Numerical Investigation of Semiempirical Relations Representing the Local Nusselt Number Magnitude of a Pin Fin Heat Sink
Research Output | Dar Al-hikmah Library | IIUM Only

Heat transfer augmentation study using air jet impingement has recently attained great interest toward electronic packaging systems and material processing industries. The present study aims at developing a nondimensional semiempirical relation, which represents the cooling rate (Nu) in terms of different geometric and impinging parameters. The spa

Data Protection Challenges in the Internet of Things Era: an Assessment of Protection Offered by Pdpa 2010
Research Output | Dar Al-hikmah Library | IIUM Only

The Internet of Things (IoT) is an emerging technology of the 21st century. It is described as the first real evolution of the Internet that could positively or negatively affect all aspects of life. The basic idea of the IoT revolves around connecting things and objects (persons, animals, cars, trees, etc.) to the Internet and enabling them to com

Development of Fatigue Detection Technique Using Photoplethysmogram Signal
Research Output | Dar Al-hikmah Library | IIUM Only

Fatigue is a subjective feeling of tiredness which has physical or mental implications. Thus, in this study we will prove the robustness and reliability of PPG signals as a fatigue detection mechanism. Undeniably, PPG signals have the superior crite-ria which are non-invasive, small in size, low power consumption as well as low in cost. A total of

Numerical Study of Heat Transfer Augmentation Using Pulse Jet Impinging on Pin Fin Heat Sink
Research Output | Dar Al-hikmah Library | IIUM Only

Pulse jet impinging laterally on the pin fin surface have a dual effect (increment and decrement) on the heat transfer rate. The present work manifests the decrement observed in heat transfer rate because of pulse jet impinging on uniform and nonuniform dimensional pin fin heat sink compared with the steady jet. In order to justify and scale the de

Comparative Study of the Performance and Economic Value of a Small Engine Fueled with B20 and B20-lpg as an Effort to Reduce the Operating Cost of Diesel Engines in Remote Areas
Research Output | Dar Al-hikmah Library | IIUM Only

Indonesia is an archipelagic country that has remote locations. In such areas, the price of diesel fuel might be very costly. Hence, it is very burdensome for the community because this type of fuel is needed by diesel engines to drive generator sets, agricultural and production purposes. The utilization of dual-fuel diesel-gas engine is expected a

Go Green in Architecture
Research Output | Dar Al-hikmah Library | IIUM Only

The term "Go Green" is a widely used term having a wide variety of meanings depending on who uses it. Going green may be perceived in three simple steps "conserve energy, reduce pollution and save money" in our day to day chorus. More you achieve them, more you are going green. It may also be the way of life in which individuals are

Measurements of the Pp → Wz Inclusive and Differential Production Cross Sections and Constraints on Charged Anomalous Triple Gauge Couplings at S√ = 13 Tev
Research Output | Dar Al-hikmah Library | IIUM Only

The WZ production cross section is measured in proton-proton collisions at a centre-of-mass energy s√ = 13 TeV using data collected with the CMS detector, corresponding to an integrated luminosity of 35.9 fb−1. The inclusive cross section is measured to be σtot(pp → WZ) = 48.09 − 0.96 + 1.00 (stat) − 0.37 + 0.44 (theo) − 2.17 + 2.39 (s

Ternary glycerol-Based Deep Eutectic Solvents: Physicochemical Properties and Enzymatic Activity
Research Output | Dar Al-hikmah Library | IIUM Only

The present study investigates deep eutectic solvents (DESs) as potential media for enzymatic hydrolysis. A series of ternary ammonium and phosphonium-based DESs were prepared at different molar ratios by mixing with aqueous glycerol (85%). The physicochemical properties including surface tension, conductivity, density, and viscosity were measured

Effect of Laser Parameters on Sequential Laser Beam Micromachining and Micro electro-Discharge Machining
Research Output | Dar Al-hikmah Library | IIUM Only

Laser beam micromachining (LBMM) and micro electro-discharge machining (μEDM) based sequential micromachining technique, LBMM-μEDM, has drawn significant research attention to utilize the advantages of both methods, i.e., LBMM and μEDM. In this process, a pilot hole is machined by the LBMM, and subsequently finishing operation of the hole is car

A Muslim’s Brief View on the Trinity: the Doctrine of Oneness of God in Christianity
Research Output | Dar Al-hikmah Library | IIUM Only

This article tries to observe the understanding of God in Christianity. The researcher chooses Christianity because the idea of God in Christianity is unique. On the one hand, Christianity claims a monotheistic religion because Christianity follows the belief system of Abraham, who understands God as one. On the other hand, Christianity also believ
