Feedback controlling against chaos
(2000)
A P-D (Proportional plus Derivative) feedback controller is proposed for the control of chaotic dynamic systems. Using this feedback law the design requirement of command matching is satisfied independently of the perturbations ...
Numerical integration of fluid dynamics problems by discrete dynamical systems
(2000)
A discrete time algorithm for the numerical solution of the Navier-Stokes equations, namely the set of nonlinear partial differential equations (PDEs) characterizing the how of viscous and compressible fluids is presented. ...
On the Julia set of the perturbed Mandelbrot map
(2000)
In this work, we present numerical results which support the smooth decomposition method of the generalized Julia set by Peintge et al., in the case of other perturbations of the Mandelbrot map studied in our previous work ...
On perturbations of the Mandelbrot map
(2000)
In this work, we propose new applications of analytic and non-analytic perturbations of the Mandelbrot map as expressed in a two-parameter deformation family of it. The influence of alternative applications of noise for ...
Evaluation of the ductility features in steel structures with softening moment-rotation behaviour based on a nonconvex optimization formulation
(2000)
In order to determine the ductility features of steel structures, several approaches have been introduced in the bibliography. In this paper a certain method is proposed which considers the actual form of the moment-rotation ...
