    The numerical studies are performed to examine the MHD free convection and mass transfer flow with thermal diffusion and dufour effects past an infinite vertical porous plate. Method of Superposition and the Shooting method ...
  • Islam, Mohammad Rafiqul (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh., 2007-06)
    Combined heat and mass transfer by mixed convection flow from a vertical porous plate with induced magnetic field, constant heat and mass fluxes has been studied. Nachtsheim Swigert iteration technique is used as the main ...
  • Molla, Md. Yahia (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh., 2007-11)
    American Mathematician Lotfi A. Zadeh in 1965 first introduced the concept of fuzzy set. He interpreted a fuzzy set on a set as a mapping from the set into the unit interval I= [0.1], which is a generalization of the ...
  • Haque, B. M. Ikramul (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh., 2008-01)
    Krylov and Bogoliubov introduced a perturbation method named "asymptotic averaging method". The method was developed only to obtain the periodic solution of second order nonlinear differential systems. Now the method is ...
  • Islam, Md. Rashidul (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh., 2008-04)
    This thesis studies extensively the nature of modular lattices and Boolean algebras. The modular lattices have been study by several authors including Abbott [2] , Birkhoff [ 3] and Rutherford [19 ]. A poset is said to ...
  • Rahman, Khaki Masudur (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh., 2008-06)
    This thesis studies the nature of Pseudocomplemented lattice. We can define a lattice in two ways; (i) Set theoretically and (ii) Algebraically. Set theoretically: A poset <L; ≤ > is a lattice if for every a, b ϵ L both ...
  • Rahman, Md. Habibur (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh., 2009-03)
    At first Krylov and Bogoliubov prcseflted a perturbation method known as the asymptotic averaging method' in the theory of nonlinear oscillations. Primarily, the method was proposed only to get the periodic solutions of ...
