Comparison of Data Correction Methods for Blockage Effects in Semispan Wing Model Testing
Research Output | Dar Al-hikmah Library | IIUM Only

Wing alone models are usually tested in wind tunnels for aerospace applications like aircraft and hybrid buoyant aircraft. Raw data obtained from such testing is subject to different corrections such as wall interference, blockage, offset in angle of attack, dynamic pressure and free stream velocity etc. Since the flow is constrained by wind tunnel

Biohydrogen Production by Dark Fermentative Bacteria Using Starchy Waste: a Review
Research Output | Dar Al-hikmah Library | IIUM Only

The need of energy from fossil fuel has become a global issue that is challenging to the humanity due to its high demand. However, fossil fuel is a non renewable form of energy which, in turn, will lead to the energy scarcity. As a matter of fact, researcher has put a strong emphasize to find the alternative source of energy. Biohydrogen produced f

Effect of Side Wind on the Directional Stability and Aerodynamics of a Hybrid Buoyant Aircraft
Research Output | Dar Al-hikmah Library | IIUM Only

Directional stability characteristics explain the capabilities of a hybrid buoyant aircraft’s performance against the side wind, which induces flow separation that is chaotic in nature and may lead to oscillations of the aerodynamic surfaces. A numerical study is carried out to estimate the effect of side wind. The boundary conditions for the com

Wind Tunnel Testing on a Generic Model of a Hybrid Lifting Hull
Research Output | Dar Al-hikmah Library | IIUM Only

In this research, an experimental investigation was carried out at the International Islamic University Malaysia - Low Speed Wind Tunnel facility on a generic model of a hybrid lifting hull. Based on the historical trends of non-rigid airships, the fineness ratio of the said hull has been selected equal to 4. Free stream velocity was kept at 20 m�

Scattering of a two-Soliton Molecule by Gaussian Potentials in Dipolar Bose–einstein Condensates
Research Output | Dar Al-hikmah Library | IIUM Only

Two bright solitons in a dipolar Bose–Einstein condensate (BEC) can form stable bound states, known as soliton molecules. In this paper we study the scattering of a two-soliton molecule by external potential, using the simplest and analytically tractable Gaussian potential barriers and wells, in one spatial dimension. Collisions of soliton molecu

Case Study of Rain Attenuation at 26 GHZ in Tropical Region (Malaysia) for Terrestrial Link
Research Output | Dar Al-hikmah Library | IIUM Only

Millimeter wave (mm Wave) is today's breakthrough frontier for emerging wireless mobile cellular networks, wireless local area networks, personal area networks, and vehicular communications. In the near future, mm Wave products, systems, theories, and devices will come together to deliver mobile data rates thousands of times faster than today&#

Establishing the Analytical Relationships for Mass and Volumetric Mass Fractions for Hybrid Buoyant Aircraft
Research Output | Dar Al-hikmah Library | IIUM Only

The current data bank of operational empty mass fraction of airships is based on available data obtained from existing and historical airships. For any design related activity, regression analysis on existing data bank of airships will not be able to provide the true picture of mass fractions of hybrid airships. This situation becomes more critical

Estimation of Pitching Moment of a Hybrid Lifting Fuselage - Disguised as Hull of an Airship
Research Output | Dar Al-hikmah Library | IIUM Only

Munk-Multhop's method is usually used for estimation of pitching moment of fuselage of conventional aircraft but application of the same for hybrid lifting fuselage had not been earlier explored. CFD methods can also be applied for the said purpose but it is difficult to separate out the portion of the moment caused by the fuselage, since the w

Evaluation of Antioxidants Activity of Momordica Charantia Using lc-Ms Metabolomics Approach
Research Output | Dar Al-hikmah Library | IIUM Only

Objectives: The present study was design to identify the significant biomarkers from M.charantia that possessing antioxidant activity using liquid chromatography-mass spectrometry (LC-MS) based metabolomics approaches. Design and method: Initially, the fruit was extracted by soaking in different solvents with different concentrations of ethanol in

Characterisation of Carotenoid and Total Retinol Equivalent Content in Ulam and Medicinal Species as Alternative Food Intervention to Combat Vitamin a Deficiency
Research Output | Dar Al-hikmah Library | IIUM Only

Vitamin A deficiency (VAD) is one of the continuous leading causes of children and pregnant women death. To overcome this malnutrition which currently affected one-third of the world population, there is always renewed interest in exploring numerous dietary sources rich in carotenoids which some of them serve as pre-cursors to vitamin A (pro- vitam
