In this paper the gradient based iterative algorithm is presented to solve the linear matrix equation AXB +CXD = E, where X is unknown matrix, A,B,C,D,E are the given constant matrices. It is proved that if the equation has a solution, then the unique minimum norm solution can be obtained by choosing a special kind of initial matrices. Two numerical examples show that the introduced iterative a...
This paper presents an efficient solution approach to tackle large-scale singlefloor process plant layout problems. Based on the mixed integer linear programming (MILP) model proposed by Papageorgiou and Rotstein [1], the final layout (i.e. coordinates and dimensions) is determined from an initial feasible solution by an iterative improvement procedure using mixed integer optimisation. The appl...

the taguchi method was applied as an experimental design to determine optimum conditions for colour removal from azo dyes solutions containing remazol yellow g by electrocoagulation (ec) using iron and steel electrodes as anode and cathode, respectively. an orthogonal array (oa9) experimental design that allows to investigation the simultaneous variations of four parameters (initial remazol ye...
Abstract Introduction: The heavy metals are the most important pollutant that their concentration in environment is increasing with cities and industrials developing. One of this metals is chromium that in the trivalent and hexavalent oxidation state used in industries such as electroplating, glass, ceramic, tannery and leather. Hexavalent chromium has proven several health hazards such as a c...
In this paper , we have presented Homotopy Perturbation Method (HPM) to solve nonlinear parabolic equation with nonlocal boundary conditions. This method provides an analytical solution by utilizing only the initial condition. The HPM allows for the solution of the nonlinear parabolic equations to be calculated in the form of a series with easily computable components. The obtained results are ...
In this paper, we propose efficient method for pre-training of deep bottleneck neural network (DBNN). Pre-training is used for initial value of network weights convergence of DBNN is difficult because of different local minimums. While with efficient initial value for network weights can avoided some local minimums. This method divides DBNN to multi single hidden layer and adjusts them, then we...
In this paper we focus on the Cauchy problem for the generalized IBq equation with damped term in $n$-dimensional space. We establish the global existence and decay estimates of solution with $L^q(1leq qleq 2)$ initial value, provided that the initial value is suitably small. Moreover, we also show that the solution is asymptotic to the solution $u_L$ to the corresponding linear equa...
