Development of low wind speed anemometer
(Indonesian Society for Knowledge and Human Development (INSIGHT), 2012)Anemometer is a measuring device used to measure the wind speed of an area. Before design or installing a wind turbine, it is important to determine the average wind speed of that particular area throughout the year. But ... -
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 ... -
Effects of radiation, joule heating and viscous dissipation on MHD Marangoni convection over a flat surface with suction and injection
(International Digital Organization for Scientific Information (IDOSI) Publications, 2013)In this paper, we studied the effects of thermal radiation, Joule heating and viscous dissipation on magnetohydrodynamics (MHD) Marangoni convection boundary layer over a flat surface. We also investigated the influence ... -
Enhancement of algorithm and investigation of heat transfer through fins
(Praise Worthy Prize S.r.l., 2013-09)Finite Element Method (FEM) and Differential Quadrature Method (DQM) are two very important numerical solution techniques to solve engineering and physical science problems. Usually elements are sub-divided uniformly in ... -

(Trans Tech Publications, 2014)The light inspection on surface finishing of most product measurement is an important feature in the industries. In this study, a lab module tester for examination on the different type quality of tissue paper quality was ... -
Formulation of weighted goal programming using the data analysis approach for optimising vehicle acoustics levels
(International Journal of Acoustics and Vibration., 2013-09)Two factors for customers to consider when purchasing a vehicle are the vehicle acoustical comfort and the vibration in the vehicle cabin, both of which contribute to a comfortable driving environment. The amount of ... -
Frequency band analysis of electrocardiogram (ECG) signals for human emotional state classification using discrete wavelet transform (DWT)
(Society of Physical Therapy Science, 2013-06)[Purpose] Intelligent emotion assessment systems have been highly successful in a variety of applications, such as e-learning, psychology, and psycho-physiology. This study aimed to assess five different human emotions ... -
Further improvement in the variational many-body wave functions for light nuclei
(American Physical Society, 2012-09)An improved variational ansatz is proposed and implemented for variational many-body wave functions for light nuclei with nucleons interacting through Argonne (AV 18) and Urbana IX (UIX) three-nucleon interactions. The new ... -
G1 scattered data interpolation with minimized sum of squares of principal curvatures
(Institute of Electrical and Electronics Engineering (IEEE), 2005-07)One of the main focus of scattered data interpolation is fitting a smooth surface to a set of non-uniformly distributed data points which extends to all positions in a prescribed domain. In this paper, given a set of ... -
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 ... -
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 ... -
