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

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 mâˆ

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

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&#

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

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

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

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

Utilization of Thermopile sensor at an early stage of human detection is challenging as there are many things produce thermal heat other than human such as electrical appliances and animals. Therefrom, an algorithm for early presence detection has been developed through the study of human body temperature behaviour with respect to the room temperat

The right of self-defense under Islamic law (Shariah) distinguishes between two concepts: private and public defense. In this article, legal and practical manifestations of the contemporary legal issue of private defense in the case of physical assaults made by non-accountable (mukallaf) offenders, such as minors and insane persons are focused.
