Improved variational many-body wave function in light nuclei
(American Physical Society, 2009-09-10)We propose and implement a simple method for improving the variational wave function of a many-body system. We have obtained a significant improvement in the binding energies, wave functions, and variance for the light ... -
Improvement of signature scheme based on the hybrid of two problems
(AIP Publishing LLC, 2013)This paper proposed an improvement of an existing signature scheme based on the hybrid of two problems. The security of this improved signature scheme is based on a hybrid of factorisation (FAC) and elliptic curve discrete ... -
Incorporating optimisation technique into Zadeh’s extension principle for computing non-monotone functions with fuzzy variable
(Penerbit Universiti Kebangsaan Malaysia (UKM), 2011-06)This paper proposes a new computational method for computing non-monotone functions that take a fuzzy interval as their arguments. The proposed method represents an implementation of optimisation technique into Zadeh’s ... -
Intelligent exit-selection behaviors during a room evacuation
(Chinese Physical Society and IOP Publishing Ltd., 2012-01)A modified version of the existing cellular automata (CA) model is proposed to simulate an evacuation procedure in a classroom with and without obstacles. Based on the numerous literature on the implementation of CA in ... -
Investigation of surface roughness on platinum deposited wafer after reactive ion etching using SF₆+Argon gaseous
(Trans Tech Publications, 2014)This paper investigates the factors that affect the surface roughness on a Platinum deposited wafer after reactive ion etching (RIE) using a combination of SF₆ and Argon gaseous. A total of three controllable process ... -
Investigation of water hammer effect through pipeline system
(Indonesian Society for Knowledge and Human Development (INSIGHT), 2012)This paper we study the condition where the water hammer effect is occurs in pipe line. Water hammer can cause the pipe to break if the pressure is high enough. The experiment will be set-up to investigate the water hammer ... -
Magnetic field effects on 3D blood flow patterns of straight and stenotic arteries
(American Scientific Publishers All rights reserved., 2013-09)This paper investigates the mathematical modeling of the biomagnetic fluid (human blood) flow in arteries with different geometries, subjected to various externally applied non-uniform magnetic fields. In allowing for the ... -
Marangoni mixed convection boundary layer flow with suction and injection
(AIP Publishing LLC, 2013)The mixed Marangoni convection boundary layer flow over a permeable surface in the presence of thermal-diffusion and diffusion-thermo effects is investigated. The governing partial differential equations are converted into ... -
MHD mixed convection stagnation point flow over a permeable surface
(AIP Publishing LLC, 2013)In this paper, the effects of suction and injection parameters on magnetohydrodynamic (MHD) mixed convection stagnation point flow are studied numerically. Using appropriate similarity transformations, the governing system ... -
Microscopic dynamics of a large-scale pedestrian evacuation model
(Academic Journals, 2012-01-09)Numerous models have been developed for estimating the time required to evacuate from a variety of places under various conditions. For high-traffic places, such as commercial and industrial buildings, it is vital to be ... -
