In this paper, we propose a universal two-dimensional (2D) absolute-cosine chaotic model (ACCM). The 2D-ACCM is composed of a nonlinear bounded cosine function and an absolute value function. It can ...

Abstract: In this paper, a novel modulation scheme called two-dimensional discrete cosine transform orthogonal frequency-division multiplexing (2D-DCT-OFDM), which extends the principles of OFDM ...

We propose a MATLAB implementation of the P 1 finite element method for the numerical solutions of the Poisson problem and the linear elasticity problem in two-dimensional (2D) and three-dimensional ...
