We propose a novel technique of automated camera calibration method to obtain internal camera parameters, which enables us to compensate the distortion of an image taken by a camera with zooming lens. The proposed method is based on image registration. First a calibration pattern is transformed onto the distorted image of the pattern using affine transformation. Then the registration of the two...

In this paper, a new approach to analyze the asymptotic, exponential and robust stability of the master-slave synchronization for Lur’e systems using time-varying delay feedback control is proposed. The discussion is motivated by the problem of transmitting information in optical communication systems using chaotic lasers. The approach is based on the Lyapunov–Krasovskii stability theory for fu...

After reviewing the source-type solution of Burgers equation with standard dissipativity, we study hypoviscous counterpart equation. 1) We determine an that governs near-identity transformation underlying its self-similar solution. 2) develop approximation scheme and construct first-order approximation. 3) obtain numerically by Newton-Raphson iteration find it to agree well Implications are giv...

General thermo-mechanical behavior of composites reinforced by shape memory alloy fibers is predicted using a three-dimensional analytical micromechanical method to consider the effect of fibers activation. Composite due to the micromechanical method can be exposed to general normal and shear mechanical and thermal loading which cause to activate the shape memory alloy fibers within polymeric m...

We consider a family of damped quasi-Newton methods for solving unconstrained optimization problems. This family resembles that of Broyden with line searches, except that the change in gradients is replaced by a certain hybrid vector before updating the current Hessian approximation. This damped technique modifies the Hessian approximations so that they are maintained sufficiently positive defi...

Abstract This paper examines a number of extrapolation and acceleration methods introduces few modifications the standard Shanks transformation that deal with general sequences. One goals is to lay out framework encompasses most known strategies.
