A novel color image LSB steganography using improved 1D chaotic map
TL;DR: Simulation and performance evaluation shows that the 1D chaotic map improved by the proposed model can overcome the existing defects sufficiently and the algorithm has a better performance than the previous methods, showing an excellent performance against statistical analysis attacks.

A modeling method for vibration analysis of cracked laminated composite beam of uniform rectangular cross-section with arbitrary boundary condition
TL;DR: In this article, the authors established an analysis model to study the vibration behavior of a cracked laminated composite beam with uniform rectangular cross-section based on the Jacobi-Ritz method and the first-order shear deformation theory (FSDT).

Dynamic analysis of composite laminated doubly-curved revolution shell based on higher order shear deformation theory
TL;DR: In this article, the authors established an analysis model for dynamic analysis of composite laminated doubly-curved revolution shell based on the Higher order Shear Deformation Theory (HSDT), and the convergence, validity and dynamic characteristics of the analytical model established in this paper are given by a series of numerical examples.

A nonlinear magneto-mechanical coupling model for magnetization and magnetostriction of ferromagnetic materials
TL;DR: In this paper, a new magneto-mechanical coupling model was proposed for ferromagnetic materials under applied stress and in magnetic fields, which can accurately predict the nonlinear changes in the magnetization and magnetostriction under the applied stress.
