Redundancy optimization of k-out-of-n system with Common-Cause Failures (CCFs) using the inspection period
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
Redundancy optimization of k-out-of-n:G system with Common-Cause Failures (CCF) are often determined by two things, level of cost (mean cost rate) of the resulting system configuration and the failure rate of each unit in ...
Effectiveness of the Morlet wavelet in generating new shortened fatigue strain signal
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
A Morlet wavelet algorithm was developed for eliminating lower wavelet coefficient amplitude hence to retain higher wavelet coefficient amplitude. The 44.8 second original fatigue strain signal was edited based on Cut Off ...
Implementation of simulated annealing for two variables non-linear function
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
Stochastic optimisation is a technique that refers to
minimisation or maximisation of a certain functions and this
algorithm has been used widely in industry, business and
computer science. In mathematic algorithm, ...
Mathematical modeling and simulation for satellite attitude control
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
In this paper, a linear mathematical model of the satellite attitude control is derived for the Gravity Gradient (GG) controls method, which represents a passive control design. Natural physical properties of the satellite ...
Linear programming model for ferry service scheduling
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
The aim of the study is to apply linear programming formulation in minimizing the number of excess passengers that used ferry services from Kuala Perlis to Kuah and vice versa during peak season. High demand of ferry ...
On some structural properties of diassociative algebras
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
The paper deals with diassociative algebras (or simply dialgebras) introduced by Loday at the end of last century. The motivation to study comes from the following fact: there are links between them and classical algebras ...
Solving a system of nonlinear equations by particle swarm optimization
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
The solution of a system of nonlinear equations is a difficult problem in numerical computation. For many numerical approaches, the convergence and performance characteristics can be highly sensitive to the initial guess ...
Lagrangian dual function solved with surrogate subgradient method: An analysis of step size rules
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
Lagrangian relaxation dual function is a technique commonly used to optimize non-convex problems. The difficulty in obtaining a solution method for the dual function is normally due to the function’s non-differentiable ...
Using MS Excel in numerical solution of ordinary differential equations
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
In this paper we focus on solving numerical ordinary differential equations (ODEs), specifically Euler and Runge-Kutta methods by writing a few small formulae and click and drag in Microsoft Excel. We study and compare the ...
Analysis flux on transformer core lamination assembled with mix between 60o- 45o T-joint using 2DFEM
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
This paper describes analysis 2DFEM on 100kVA 3phase distribution transformer assembled with mix between 60-45 T-joint and mitred lap corner joint with stagger yoke and limb for one lamination. The simulation involves the ...
