Patient monitoring helps increasing the mortality by timely notification of exceeding vital signs. By using the vital sign data the critical care staff can make necessary life saving interventions. This requires the underlying network to be very robust so that timely and error free information flow can be guaranteed. Moreover there is a need for a cost effective and robust network technology fo...

The Bluetooth specification defines the notion of interconnected piconets, called scatternets, but does not define the actual mechanisms and algorithms necessary to set up and maintain them. The operation of a scatternet requires some Bluetooth units to be interpiconet units (gateways), which need to time-division multiplex their presence among their piconets. This requires a scatternet-schedul...

Society’s welfare is very dependent on the effective performance of Critical Infrastructure (CI). Nowadays, CI constitutes a network of interconnected and interdependent entities. This means that a serious event in one CI can originate cascading events in the rest, leading to a serious crisis. As a consequence, Crisis Management (CM) and Critical Infrastructure Protection (CIP) should converge ...

Catastrophic failures in power grid due to maloperation of traditional backup protection system (e.g. third zone of distance relays) was one of the main causes of many cascade trips. This paper assess a new wide-area backup protection system (WABPS) based on phasor measurement units (PMU), to improve third zone of distance relays to avoid its mal-operation. Based on this assessment, phasor meas...

This paper reports about simulation studies carried out in connection with the new pump storage power plant Goldisthal of the German power company VEAG. Two units are equipped with double fed induction machine drives and thus, they are able to vary the speed. A simulation model was developed to investigate the dynamic behavior of the units in interaction with the power system. As a result of a ...

We are seeing the advent of large scale, heterogeneous systems comprised of homogeneous general purpose cores intermingled with customized heterogeneous cores and interconnected to diverse memory hierarchies. The presence of accelerators requires support for new programming abstractions and run-time environments that can efficiently harvest platform resources comprised of general purpose and sp...

The structure of the title compound, [Sm(2)(C(4)O(4))(3)(H(2)O)(4)](n), consists of infinite-chain structural units, built from edge-sharing samarium SmO(7)(H(2)O)(2) polyhedra and linked via bis-monodendate squarate (sq1) groups. The chains extend along [100] in a zigzag mode and are interconnected by bis-chelating squarate (sq2) ligands into layers parallel to (101). Inter-layer hydrogen bond...

Most common feature ranking methods are based on the statistical approach. This paper compare several statistical methods with new method for feature ranking derived from data mining process. This method ranks features depending on percentage of child units that survived the selection process. A child unit is a processing element transforming the parent input features to the output. After train...

Web Modeling Language (WebML, http://webml.org) is a notation for visually specifying complex Web sites at the conceptual level. All the concepts of WebML are specified both graphically and in XML; in particular, navigation and composition abstractions are based on a restricted number of hypertext components (units) which are assembled into pages and interconnected by links. During implementati...

This paper presents a hierarchical approach to the problems inherent in parts of real-time strategy games. The overall game is decomposed into a hierarchy of sub-problems and an architecture is created that addresses a significant number of these through interconnected machinelearning (ML) techniques. Specifically, individual modules that use a combination of case-based reasoning (CBR) and rein...
