Delay-Dependent Robust Asymptotically Stable for Linear Time Variant Systems
In this paper, the problem of delay dependent robust asymptotically stable for uncertain linear time-variant system with multiple delays is investigated. A new delay-dependent stability sufficient condition is given by using the Lyapunov method, linear matrix inequality (LMI), parameterized first-order model transformation technique and transformation of the interval uncertainty in to the norm ...
متن کاملConductivity Cusp in a Disordered Metal
true for the study of localization in one dimension, for which the T ' dependence of the resist3nce predicted by Thouless remains to be observed. Copper wires, with thicknesses of 100 A, widths of 1 pm, and lengths of 1 cm would seem to be well suited for that purpose. We thank the Belgian Interuniversitair Instituut voor Kernwetenschappen for financial support, and the Nuclear Research Center,...
متن کاملSample-dependent first-passage-time distribution in a disordered medium.
Above two dimensions, diffusion of a particle in a medium with quenched random traps is believed to be well described by the annealed continuous-time random walk. We propose an approximate expression for the first-passage-time (FPT) distribution in a given sample that enables detailed comparison of the two problems. For a system of finite size, the number and spatial arrangement of deep traps y...
متن کاملScale-dependent correction to the dynamical conductivity of a disordered system at unitary symmetry
Anderson localization has been studied extensively for more than half a century. However, while our understanding has been greatly enhanced by calculations based on a small expansion in d = 2 + dimensions in the framework of nonlinear sigma models, those results cannot be safely extrapolated to d = 3. Here we calculate the leading scale-dependent correction to the frequency-dependent conductivi...
متن کاملOFFPRINT Transmission thresholds in time-periodically driven nonlinear disordered systems
We study energy propagation in locally time-periodically driven disordered nonlinear chains. For frequencies inside the band of linear Anderson modes, three different regimes are observed with increasing driver amplitude: 1) below threshold, localized quasiperiodic oscillations and no spreading; 2) three different regimes in time close to threshold, with almost regular oscillations initially, w...
