We investigate experimentally a Fermi golden rule in two-edge and five-edge microwave networks with preserved time reversal invariance. A gives rates of decay states obtained by perturbing embedded eigenvalues graphs networks. show that the are connected topological resonances analyzed systems we find trajectories complex plane.

A novel Markov random field (MRF) model is proposed for roof-edge (as well as step-edge) preserving image smoothing. Image surfaces containing roof-edges are represented by piecewise continuous polynomial functions governed by a few parameters. Piecewise smoothness constraint is imposed on these parameters rather than on the surface heights as is in traditional models for step-edges. In this wa...

In recent years, digital cameras have become the dominant image capturing devices. They are now commonly included in other digital devices such as mobile phones and PDAs, and have become steadily cheaper, more complex and powerful. In such devices, in order to keep costs down, only incomplete color information is recorded at each pixel location. Interpolating a full three-color image by estimat...

Herding defines a deterministic dynamical system at the edge of chaos. It generates a sequence of model states and parameters by alternating parameter perturbations with state maximizations, where the sequence of states can be interpreted as “samples” from an associated MRF model. Herding differs from maximum likelihood estimation in that the sequence of parameters does not converge to a fixed ...

Constructing a sparse spanning subgraph is a fundamental primitive in graph theory. In this paper, we study this problem in the Centralized Local model, where the goal is to decide whether an edge is part of the spanning subgraph by examining only a small part of the input; yet, answers must be globally consistent and independent of prior queries. Unfortunately, maximally sparse spanning subgra...

in recent years due to improvements of technology within automobile industry, design process of advanced driver assistance systems for collision avoidance and traffic management has been investigated in both academics and industrial levels. detection of traffic signs is an effective method to reach the mentioned aims. in this paper a new intelligent driver assistance system based on traffic sig...
