    • Microscopic dynamics of a large-scale pedestrian evacuation model 

      Lim, Eng Aik (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 ...

    • Incorporating optimisation technique into Zadeh’s extension principle for computing non-monotone functions with fuzzy variable 

      Muhammad Zaini, Ahmad; M. K., Hasan (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 ...

    • Implementation weather-type models of capacitated arc routing problem via heuristics 

      Zuhaimy, Ismail; Muhamad Fadzli, Ramli (Science Publications, 2011)
      In this study, we introduced a new and real-life condition of Capacitated Arc Routing Problem (CARP), a model that represents vehicle's operation in waste collection. In general, we studied the element of rain drops that ...

    • A new fuzzy version of Euler's method for solving differential equations with fuzzy initial values 

      Muhammad Zaini, Ahmad; M. K., Hasan (Universiti Kebangsaan Malaysia (UKM), 2011-06)
      This paper proposes a new fuzzy version of Euler’s method for solving differential equations with fuzzy initial values. Our proposed method is based on Zadeh’s extension principle for the reformulation of the classical ...

    • Exit-selection behaviors during a classroom evacuation 

      Lim, Eng Aik (Academic Journals, 2011-07)
      A modified version of the existing Cellular Automata (CA) model is proposed to simulate an evacuation experiment conducted in a classroom with and without obstacles. This work present the use of CA with neural network ...

    • Visual based automatic coin counting system using neural network 

      Mohd Syafarudy, Abu; Lim, Eng Aik (University Teknologi Malaysia (UTM)Department of Mathematics, 2009)
      A new intelligent coin-counting system is described in this paper. The proposed system is effective and flexible for the purpose of performing coin-counting using image captured from webcam. Image processing techniques are ...

    • A new method for computing continuous functions with fuzzy variable 

      Muhammad Zaini, Ahmad; Hasan, M.K.; De Baets, B. (Asian Network for Scientific Information (ANSInet), 2011)
      This study proposes a new method for computing f(U) where f is a real continuous function and U is a fuzzy interval. The computation of f(U) is performed by incorporating optimisation technique into Zadeh's extension ...

    • Adaptive Neuro-Controller for three axes attitude control of innovative satellite 

      Siti Maryam Sharun; Mohd Yusof Mashor, Prof. Dr.; M. N. Norhayati; W. N. Hadani; Sazali Yaacob, Prof. Dr. (Science Academy, 2011-03)
      There exists so many disturbance torques in space which may deviate the satellite from the desired attitude. To overcome the effects of the disturbance torques some stabilization has to be provided to the satellite. This ...

    • A new approach to incorporate uncertainty into Euler's method 

      Muhammad Zaini, Ahmad; M. K., Hassan (Hikari Ltd, 2010)
      Fuzzy set provides a powerful technique to introduce uncertainty into numerical methods. However, the computations of fuzzy sets often face difficult problems. This is due to non-applicability of common existing methods, ...

    • Curve analysis for real-time crowd estimation system 

      Lim, Eng Aik; Zarita, Zainuddin (European Journals Inc., 2009-06-15)
      The crowd monitoring system has been widely used in many areas such as transportation control and safety management. The aim of a crowd monitoring system is to count the number of people in a confined area. There are ...

    • Numerical solution of the boundary layer flow over an exponentially stretching sheet with thermal radiation 

      Biliana, Bidin; Roslinda, Nazar (European Journals Inc., 2009-07)
      In this paper, the problem of steady laminar two-dimensional boundary layer flow and heat transfer of an incompressible viscous fluid with a presence of thermal radiation over an exponentially stretching sheet is investigated ...

    • Improved variational many-body wave function in light nuclei 

      Qamar Nasir, Usmani, Prof. Dr.; Singh, A.; Khairul Anwar, Mohamad Khazali; Rawitscher, G. (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 ...

    • Core nucleus dynamics in Λ hypernuclei 

      Qamar Nasir, Usmani; Bodmer, A. R.; Zaliman, Sauli, Prof. Madya (World Scientific Publishing Co, 2009-06)
      We develop a Thomas Fermi theory to study the core polarization effects in Λ hypernuclei. Nuclei in the range of 10B to 243Am are included. Core polarization energies and changes in rms radii due to presence of Λ are ...
