The Internet has become the common medium for content distribution. Searching content using keywords is well-known. But there are many shortcomings to it. Users cannot search within the content and on many of the attributes of the content, i.e., other than its name. Content is also becoming increasingly decentralized. New mechanisms allowing access to complex distributed content is needed. We i...

In 1948, when Norbert Wiener published his path breaking work Cybernetics: Communication and Control in the Animal and the Machine, computer technology was in its infancy. Most computers that were needed to implement his ideas were of analog type, certainly in animals but also in machines. They were barely enough for executing simple algorithms, for example for extrapolating stationary time ser...

Large scale high-performance computing systems pose a tough obstacle for todays program analysis tools. Their demands in computational performance and memory capacity for processing program analysis data exceed the capabilities of standard workstations and traditional analysis tools. The sophisticated approaches of Vampir NG (VNG) and the Debugging Wizard DeWiz intend to provide novel ideas for...

Efficient IPv6 packet forwarding is still a major bottleneck in todays networks. Especially in the internet core we are faced with very large routing tables and a high number of high-speed links. In addition economical restrains exist in terms of manufacturing and operation costs. So demand is high for efficient IPv6 packet forwarding mechanisms. In the last few years a lot of work has been don...

Strategic planning must be provided in libraries of all kinds for their designated positioning in todays knowledge society. The following concept points out, how a systematic review and assessment is enabled. On this fundament, positioning in the knowledge society, an ongoing optimization and sustainable enhancement of the library will be possible – both nationally and internationally seen. 1 D...

High-order filters, such as inductor-capacitor-inductor ( LCL) filter, have been popular in grid-tied power converters. Although featuring small size, LCL filters are not grid friendly due to inherent resonance, especially when a large number of converters parallel operation todays electric attain modularity, reliability, and redundancy advantages. Thus, this article reconsiders the low-order L...

A massive amount of medical data is available in healthcare industry, which can be utilized to extract useful knowledge. Clinical Decision Support System (CDSS) used improve patient’s safety by minimizing errors. Heart disease one the major chronic maladies even todays’ world. Many researchers have employed different mining techniques predict heart disease. The objective proposed framework accu...

While standard processors achieve supercomputer performance, a performance gap exists between the interconnect of MPP's and COTS. Standard solutions like Ethernet can not keep up with the demand for high speed communication of todays powerful CPU's. Hence, high speed interconnects have an important impact on a cluster's performance. While standard solutions for processing nodes exist, communica...

The Guaranteed Frame Rate service category is currently under discussion for incorporation into the specification documents of the ATM-Forum. The concept of the GFR service is to provide a minimum service guarantee to classical best-effort services, taking into account the frame-based nature of todays data-traffic. In this paper we present a discrete-time analysis of the GFR service and discuss...

Todays multimodal systems, which allow full-body (3D) gestures and speech as input modalities, are quite restricted to easily interpretable coverbal gestures with a prede ned shape and meaning. In this paper, we propose methods to abstract the concrete shape of gestures by using high-level features and to integrate them with coexpressive words using their phonological attributes. The applicatio...
