The physics of non-equilibrium many-body systems is one of the most rapidly expanding areas of theoretical physics. Traditionally used in the study of laser physics and superconducting kinetics, these techniques have more recently found applications in the study of dynamics of cold atomic gases, mesoscopic and nano-mechanical systems. The book gives a self-contained presentation of the modern f...

Goal modelling usually takes place during the early information systems development phase known as requirements engineering (RE). RE is a key factor for project success where a good tool support is necessary. Several goal-modelling tools exist and several approaches can be used to evaluate them. In this paper, we report on an experiment to evaluate two goal-modelling tools KAOS/Objectiver and i...

Several misconceptions about the application of information theory in natural science are widespread in philosophy. It is therefore necessary to clarify the assumptions required for informational measurements to have significance. Contemporary accounts of informational measurements in the natural sciences are stuck between “the Scylla of meaning and the Charybdis of causation.” [26, p. 191]. He...

This paper is concerned with the problem of exponential stabilization for a class of uncertain nonlinear systems with state delay by means of periodically intermittent control. Based on the Lyapunov-Krasovskii functional approach, several sufficient conditions of exponential stabilization for this class of uncertain nonlinear systems with state delay are proposed, which have been expressed in t...

In this paper two external schema generation algorithms are presented. These algorithms are defined in the framework of the new external schema definition methodology for OODBs put forward in (Samos, 1995); they generate an external schema from a set of classes selected from those existing in an external schema definition repository. Their main characteristic is that they avoid the generation o...
