Many commercial microprocessor architectures support translation lookaside buffer (TLB) entries with multiple page sizes. This support can be used to substantially reduce the overhead introduced by TLB misses incurred when the processor runs an application with a large working set. Applications are currently not able to take advantage of this hardware feature because most commercial operating s...

As electronics and computers become an ever-bigger part of our life there is a growing need for creating higher-quality software faster. Visualizing the structure, execution and model of programs can improve the development process. Numerous methods and styles exist for visualizing different software artifacts but, despite previous efforts, visual programming has only very limited use in indust...

Recently DLR has developed and constructed a new experimental radar instrument for various applications like radar signature collection, SAR/ISAR imaging, motion detection, tracking, etc., where high performance and high flexibility have been the key drivers for system design. Consequently a multipurpose and multi-channel radar called GigaRad is operated in X band and allows an overall bandwidt...

Recent work has explored the idea of using trust networks to supplement ratings information in community-based information systems, including algorithms to infer missing values in the trust network. Current trust inference algorithms sometimes make undesirable inferences because they do not fully use information about distrust and sometimes make inferences based on weak support. Further, many a...

This paper describes the part of a recommendation system designed for the recognition of film reviews (RRSS). Such a system allows the automatic collection, evaluation and rating of reviews and opinions of the movies. First the system searches and retrieves texts supposed to be movie reviews from the Internet. Subsequently the system carries out an evaluation and rating of the movie reviews. Fi...

Many programs could improve their performance by adapting their memory use according to availability. If memory is available, a web browser or DNS server could use a larger cache; if there is memory pressure, they could use a smaller one. Memory adaptations are also becoming increasingly important for scalability: server consolidation is being done more aggressively and end-users want to run th...

Video security is becoming more and more important today. CCTV (closed circuit television), after broadcast television, is currently migrating from analogue to digital. At the same time, electronics have rapidly progressed in miniaturizing components and standardization initiatives have became popular in the IT world. Due to these innovations, it is now possible to deploy easily and rapidly CCT...

This report describes the MILOS Multimedia Content Management System: a general purpose software component tailored to support design and effective implementation of any digital library application. MILOS supports the storage and content based retrieval of any multimedia documents whose descriptions are provided by using arbitrary metadata models represented in XML. MILOS is flexible in the man...
