In this paper, we investigate the robust stability problem of a class of LTI discrete uncertain singularly perturbed time-delay systems. If the singular perturbation parameter of these systems is sufficiently small, they can be separated into two reduced-order subsystems, the slow subsystem and fast subsystem. Two stability criteria for the slow and fast subsystem of the uncertain system are th...

The problem of unbounded uniaxial chiral omega media in the presence of both static electric and magnetic point charges is investigated. For this purpose scalar electric and magnetic potentials in these media are introduced. Using these potentials, the corresponding electric and magnetic fields are determined. The similar problem of static electric and magnetic current sources with the goal of ...

At the upcoming SPS/IPC/Drives 2013 exhibition for electric automation technology experts from the Christian Doppler research laboratory CDL-Flex at the Vienna University of Technology will present and discuss applications for industry partners based on the Automation Service Bus® (ASB) for the integration of software tools, data, and engineering processes and added-value components, e.g., sema...

Currently, several offline digital simulation software tools are available, with varying degrees of modeling and simulation capabilities. This paper aims to compare the capabilities of two program packages for electric network simulation: ATP-EMTP and PSCAD/EMTDC for modeling lightning overvoltages. 2000 Mathematics Subject Classification: 68Uxx/Subject Classification for Computer Science. 281,...

We present a tool for annotation of se­ mantic inter­sentential discourse rela­ tions on the tectogrammatical layer of the Prague Dependency Treebank (PDT). We present the way of helping the annotators by several useful features implemented in the annotation tool, such as a possibility to combine surface and deep syntactic representation of sen­ tences during the annotation, a possibili­ ty to ...

Essentially all current software engineering tools share a common technological approach: They use a shallow representation of software objects and manipulate this representation using procedural methods. This approach has the benefit that it allows one to get off to a fast start and quickly provide a tool that delivers benefits. In addition, software engineering tools can undoubtedly be extend...
