APPROXIMATION OF THE NONLINEAR DEPENDENCIES IN HARMONIC BALANCE EQUATIONS [PDF]
Proceedings on Engineering Sciences, 2023 A new algorithm is presented to reduce computational costs in solving harmonic balance equations obtained by separating state variables. In the author's previous works, an approach was proposed where the vector (matrix) of unknowns is replaced by two ...

On the Positive Definite Solutions of a Nonlinear Matrix Equation [PDF]
Journal of Applied Mathematics, 2013 Summary: The positive definite solutions of the nonlinear matrix equation \(X^s + A^\ast f(X)A = Q\) are discussed. A necessary and sufficient condition for the existence of positive definite solutions for this equation is derived. Then, the uniqueness of the Hermitian positive definite solution is studied based on an iterative method proposed in this ...

A collocation method to the solution of nonlinear fredholm-hammerstein integral and integro-differential equation [PDF]
Journal of Hyperstructures, 2013 This paper presents a computational technique for the solution of the nonlinear Fredholm-Hammerstein integral and integrodifferential equations. A hybrid of block-pulse functions and the second kind Chebyshev polynomials (hereafter called as HBC) is used
