Web1 de abr. de 2024 · The gradient neural network (GNN) method is a novel approach to solving matrices. Based on this method, this paper improves the gradient neural network (IGNN) model with a better effect. The convergence speed is increased by replacing the X i − 1 ( k) matrix in the original gradient neural network with the current matrix X i − 1 ( k + 1).

On ADI Method for Sylvester Equations

WebWe propose a fast algorithm for computing optimal viscosities of dampers of a linear vibrational system. We are using a standard approach where the vibrational system is first modeled using the second-order structure. This structure yields a quadratic eigenvalue problem which is then linearized. Optimal viscosities are those for which the trace of the … Web10 de abr. de 2024 · The method is based on the concept of the analog equation, which in conjunction with the boundary element method (BEM) enables the spatial discretization and converts a partial FDE into a system ... chillcap mountain
