A novel approach for collision-free path planning of a multiple degree-of-freedom (DOF) articulated robot in a complex environment is proposed. Firstly, based o
In this paper, some estimations of bounds for determinant of Hadamard product of H-matrices are given. The main result is the following: if A = (aij) and B = (bi
The trust region approach has been extended to solving nonlinear constrained optimization. Most of these extensions consider only equality constraints and requi
In this paper, we show how to use wavelet to discretize the boundary integral equations which are both singular and ill-conditioned. By using an explicit diagon
This paper deals with H-stability of Runge-Kutta methods with variable stepsize for the system of pantograph equations. It is shown that both Runge-Kutta method
In this paper, a dual approximate expression of the exact solution for mixed boundary value problems of second order elliptic PDE with small periodic coefficien
In this paper we introduce a primal-dual potential reduction algorithm for positivesemi-definite programming. Using the symetric preserving scalings for both pr
