The study of particle filter for satellite angular rate estimation without rate sensor measurement
(EDP Sciences, 2018)This paper studies particle filter algorithm to estimate the angular rate of a satellite without the rate sensor measurements. In this work, the performance of the algorithm is studied in terms of capability to estimate ... -
Bioinformatics: prospect, application and the way forward
(Universiti Malaysia Perlis, 2008)The world of bioinformatics is fast expanding into the mainstream of both molecular and computational biology. Bioinformatics is a new discipline that can be described as the science of collecting, modelling, storing, ... -
Unsteady viscous flow and heat transfer due to a permeable stretching/shrinking cylinder
(AIP Publishing LLC, 2013)An analysis is carried out to investigate the unsteady viscous flow and heat transfer due to a permeable stretching/shrinking cylinder. The unsteady Navier-Stokes equations are first transformed to nonlinear ordinary ... -
Stretching surface in rotating viscoelastic fluid
(Shanghai University and Springer-Verlag Berlin Heidelberg, 2013-08)The boundary layer flow over a stretching surface in a rotating viscoelastic fluid is considered. By applying a similarity transformation, the governing partial differential equations are converted into a system of nonlinear ... -
Unsteady viscous flow over a shrinking cylinder
(Elsevier, 2013-04)The unsteady viscous flow over a shrinking cylinder with mass transfer is studied. Using a similarity transformation, the unsteady Navier-Stokes equations are reduced to nonlinear ordinary differential equations. Numerical ... -
A hybrid method for solving fuzzy differential equations
(Medwell Journals, 2013)This study proposes a hybrid method called Particle Swarm Optimization-Fuzzy Euler Method (PSOFEM) for solving fuzzy differential equations. The PSOFEM is obtained by embedding a particle swarm optimization technique in a ... -
Nuclear matter and surface clustering
(IOP Publishing Ltd, 2013)We demonstrate that the binding energy per nucleon of symmetric nuclear matter (SNM) (with Coulomb interaction switched off and N Z) in the limit of zero density approaches to its value, uv, at the saturation density, where ... -
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 ... -
Solving standard traveling salesman problem and multiple traveling salesman problem by using branch-and-bound
(AIP Publishing LLC, 2013)The standard Traveling Salesman Problem (TSP) is the classical Traveling Salesman Problem (TSP) while Multiple Traveling Salesman Problem (MTSP) is an extension of TSP when more than one salesman is involved. The objective ... -
Staff selection problem under uncertainty condition
(Medwell Journals, 2013)Hiring the right person for the right position is the core to the success of an organisation. Some organizations have suggested to create an ideal candidate that fulfilled all requirements which needed for a particular ... -
Hamming and hausdorff distance measures for staff selection problem: A comparison
(Medwell Journals, 2013)Selecting the right person to a particular job needs a lot of considerations, especially in a growth company. To solve this problem, many organisations have created an ideal candidate that fulfils all requirements for a ... -
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 ... -
The effect of magnetisation and Lorentz forces in a two-dimensional biomagnetic channel flow
(AIP Publishing LLC, 2013)The present paper studies the fundamental problem of a Magnetohydrodynamics (MHD) behaviour of the biomagnetic fluid flow in a channel under the influence of a spatially varying magnetic field. The governing equation ... -
Projection of postgraduate students flow with a smoothing matrix transition diagram of Markov chain
(AIP Publishing LLC, 2013)This paper presents a case study of modeling postgraduate students flow at the College of Art and Sciences, Universiti Utara Malaysia. First, full time postgraduate students and the semester they were in are identified. ... -
Optimisation of acoustical comfort in vehicle cabin using goal programming
(Inderscience Enterprises Ltd., 2013)Car cabin acoustical comfort is one of the main features that may attract customers to purchase a new vehicle. The noise in a passenger car cabin is closely related to the vibration generated in the vehicle system. In this ... -
Noise annoyance fuzzy index in passenger car cabin
(Inderscience Enterprises Ltd., 2013)Vehicle acoustical comfort and vibration in passenger car cabin are the factors which attract buyers to a vehicle, in order to have a comfortable driving environment. The comfort of the driving will affect the driver by ... -
Formulation of weighted goal programming using the data analysis approach for optimising vehicle acoustics levels
