Solving fuzzy fractional differential equations using Zadeh's extension principle
(Hindawi Publishing Corporation, 2013)
We study a fuzzy fractional differential equation (FFDE) and present its solution using Zadeh's extension principle. The proposed study extends the case of fuzzy differential equations of integer order. We also propose a ...
Reductions and new exact solutions of the density-dependent Nagumo and Fisher equations
(Springer Science+Business Media Dordrecht., 2013-10)
We show that conservation laws and their corresponding multipliers can be used to reformulate systems of partial differential equations and obtain some new classes of solutions. By applying the generalized double-reduction ...
Some fuzzy techniques for staff selection process: A survey
(AIP Publishing LLC, 2013)
With high level of business competition, it is vital to have flexible staff that are able to adapt themselves with work circumstances. However, staff selection process is not an easy task to be solved, even when it is ...
The study of gravity gradient effect on attitude of low earth orbit satellite
(AIP Publishing LLC, 2013)
Simulations and mathematical models are increasingly used to assist the process of decision making in engineering design. The objective of this paper is to simulate the linear attitude dynamics of small satellites under ...
Bayesian extreme modeling for non-stationary air quality data
(AIP Publishing LLC, 2013)
The aim of this paper is to model the non-stationary Generalized Extreme Value distribution with a focus on Bayesian approach. The location parameter is expressed in terms of linear trend over the time period while constant ...
Quartic B-spline and two-step hybrid method applied to boundary value problem
(AIP Publishing LLC, 2013)
Boundary value problem of second order ordinary differential equation (ODE) has been identified as a problem. However, this work will focus on solving a special case of second order ODE. Special case of second order ODE ...
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 ...
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. ...
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 ...
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 ...
