In this paper, the dispersion of carbon nanotubes (CNTs) in cement matrix was analyzed by Three-dimensional Monte Carlo Simulation. A Hard core model was employed which was not allow the intersection among CNTs in a simulated three-dimensional representative volume element (3-D RVE). The position and the orientation of CNTs were assumed to follow the uniformly random distribution. The results showed that CNTs were dispersed randomly and it was helpful for the further simulation calculation about mechanical, conductivity and piezoresistivity properties.

A novel method based on Euclidean algorithm is proposed to solve the problem of blind recognition of binary Bose–Chaudhuri–Hocquenghem (BCH) codes in non‐cooperative applications. By carrying out iterative Euclidean divisions on the demodulator output bit‐stream, the proposed method can determine the codeword length and generator polynomial of unknown BCH code. The computational complexity is derived as O (n 3 ). Simulation results show the efficiency of the proposed method.
