Damage assessments in three dimensional (3D) textile composites subjected to mechanical loading can be performed by non-destructive and destructive techniques.T
The symmetric and the asymmetric double-chain Bose-Hubbard Models (BHMs) are studied by the mean-field theory. By using Landau s quantum phase transition theory
We construct one multi-sender authentication code by algebraic combination method from eigenvalues and eigenvectors of the matrix over nite elds. Some parameter
