    A diverse set of networking technologies have been trialed in developing transport solutions for tomorrow's multimedia services. Due to the various objectives, those services are foreseen to be carried over multiparty networks, based on different transport technologies. Therefore, smooth service supply requires that operators support multiple transport systems or at least offer interconnectivity b... View full abstract»

    Software reliability is closely influenced by the creation, manifestation and impact of software faults. Consequently, software reliability can be improved by treating software faults properly, using techniques of fault tolerance, fault removal, and fault prediction. Fault tolerance techniques achieve the design for reliability, fault removal techniques achieve the testing for reliability, and fau... View full abstract»

    Indexing video data is essential for providing content based access. This paper develops a data model and a rule-based query language for video content based indexing and retrieval. The data model is based on the notion of generalized strata, which can be seen as a set of intervals. Each interval can be analyzed to extract symbolic descriptions of interest that can be put into a database. This dat... View full abstract»

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (828 KB)

    The traditional navigational design techniques do not provide a good way of handling the complexity of the navigational path of hypermedia systems, such as a learning system on the Web. When the number of pages (or nodes) of the learning system grows, the links among these pages increase exponentially. This makes the navigational design diagram of a twenty page, e.g., hypermedia learning system al... View full abstract»

    The continuing explosive growth of the web has not been matched by an adequate enhancement of the infrastructure on which it depends. Both consumers and producers are often left frustrated at the disappointingly slow speed of service. Yet there has been little systematic attempt to analyse the sources of delay experienced by users. We present a structured timing model which covers the entire perio... View full abstract»

    The location-allocation problem consists of finding the best selection of points to open facilities (location) and the way for serving the users (allocation). In most cases these problems result in being NP hard. For this reason, heuristic approaches constitute suitable tools to solve the problems. Two well known heuristic techniques are genetic algorithms and multistart search. We consider a hybr... View full abstract»

    Theoretically, conformance yields interworking and interoperability. However, experience has shown problems even when systems are conforming to the same standard. By having a glance at its methodology, conformance testing addresses the tested system as an isolated entity. Prior to real procurement on the other hand, network operators apply a set of modifications that make a system applicable to th... View full abstract»

    Many algorithms in the field of scientific visualization require high computational capacity. In general, low-end machines are not capable of delivering sufficient performance to achieve interactivity. Even worse, to generate high quality images of large data sets, the necessary time is in the order of minutes. Besides algorithmic optimizations, parallelization is necessary to quicken the computat... View full abstract»
