A key technique for the verification of programs is counterexampleguided abstraction refinement (CEGAR). In a previous approach, we developed a CEGAR-based algorithm for the modal μ-calculus, where refinement applies only locally, i.e. lazy abstraction techniques are used. Unfortunately, our previous algorithm was not completely lazy and had some further drawbacks, like a possible local state e...

Abstract: Robust decoupling of the lateral and yaw motions of a car has been achieved by feedback of the integrated yaw rate into front wheel steering. In the present paper the yaw disturbance attenuation is analyzed for a generic single-track vehicle model. The frequency limit, up to which yaw disturbances are attenuated, is calculated. For specific vehicle data, it is shown that this control ...

In this paper we develop an automata-theoretic framework for reasoning about infinite-state sequential systems. Our framework is based on the observation that states of such systems, which carry a finite but unbounded amount of information, can be viewed as nodes in an infinite tree, and transitions between states can be simulated by finite-state automata. Checking that a system satisfies a tem...

Let G= (V,E,σ,μ) be a simple connected undirected fuzzy graph. In this paper, we use a fuzzy graph model to represent a traffic network of a city and discuss a method to find the different type of accidental zones in a traffic flows. This paper is based on fuzzy coloring of fuzzy graphs and fuzziness of vertices. Using this approach, we can minimize the total waiting time of a traffic flow. It ...

As more easily mined deposits are depleted, the reserves are becoming more limited and less favorable. Deposits of coal or trona that are being longwall mined are deep and are getting deeper. Coal bursts and bumps frequently occur within development entries in longwall mining of deep mines due to high stresses. This paper presents a novel patented longwall mining layout “Longwall Mining with Sp...

A new approach to producing a composite material with negative refraction index is demonstrated. It is shown that a photonic structure which consists of two dielectric materials, with positive and negative dielectric permittivities, can support electromagnetic waves which exhibit the unusual electromagnetic property of left-handedness (or negative refraction index). These electromagnetic waves ...
