Watermarking is one of the best solutions for copyright protection and authentication of multimedia contents. In this paper a hybrid scheme is proposed using wavelet and shearlet transforms with singular value decomposition. For better security, Arnold map is used for encryption. Examining the results and comparing with other methods show that this hybrid proposed scheme with simultaneous utili...
this paper presents a hybrid method for the optimization of forging process of an aerofoil blade. preform shape and die parting-line angle are optimized in order to minimize the volume of the unfilled die cavity, material waste, forging forces. the overall optimization scheme used in this research work includes a multi-objective approach that is combination of response surface and finite elemen...
Abstract We conduct a condition number analysis of Hybrid High-Order (HHO) scheme for the Poisson problem. find statically condensed system to be independent faces in each element, or relative size between an element and its faces. The dependence on polynomial degree is tracked. Next, we consider HHO schemes cut background meshes, which are commonly used unfitted discretisations. It well known ...
This paper proposes a hybrid control scheme for the synchronization of two chaotic Duffing oscillator system, subject to uncertainties and external disturbances. The novelty of this scheme is that the Linear Quadratic Regulation (LQR) control, Sliding Mode (SM) control and Gaussian Radial basis Function Neural Network (GRBFNN) control are combined to chaos synchronization with respect to extern...
Using the discrete fractional calculus, a novel fractional-order food chain model for case of strong pressure on preys map is proposed. Dynamical behaviors involving stability analysis its equilibrium points, bifurcation diagrams and phase portraits are investigated. It demonstrated that can exhibit variety dynamical including stable steady states, periodic quasiperiodic dynamics. Then, hybrid ...
