    This paper presents a real-time entropy compression/decompression unit for disparity map information used in 3D teleconferencing systems. The disparity map data form a constant bit rate data stream which has to be transmitted through an ATM channel supporting lower data rates. The selection of the proper compression algorithm must be based on the durability of the regenerated data to various types... View full abstract»

    The paper presents the PROMIS tool, a new network management tool based on a distributed architecture of traffic probes. PROMIS allows authorized users to monitor traffic from any WAN segment using a WWW console or a Tcl/Tk graphic interface. In contrast to current network monitoring platforms based in SNMP (Simple Network Management Protocol) or RMON (Remote network MONitor), PROMIS is based on a... View full abstract»

    This paper is divided into two parts to reveal the interconnection between asynchronous transfer mode (ATM) and Ethernet, and to guarantee quality of service (QoS) for the multimedia data transmission. First, we have to solve the addressing problem. We discuss the addressing model for classical IP over ATM, LAN emulation, Peer model and Next Hop Resolution Protocol (NHRP). We then propose our addr... View full abstract»

  • A fast metric approach to feature subset selection

    Publication Year: 1998, Page(s):733 - 736 vol.2

    A simple approach to feature subset selection is proposed. During the training stage, the method selects the features that simultaneously minimize the within-class distance and maximize the between-class distance. Experiments performed on the Iris Plants Database and the Pima Indians Diabetes Database show that the approach is practical because it is fast and yet the correct classification rates a...

    The World Wide Web consists not only of informational, but also computational resources. However these resources, especially computational ones are underutilized. One characteristic of the Web is its ever changing structure; for instance, nodes are dynamically added and removed. This makes it difficult, if not impossible, to draw a complete and accurate picture of available resources. We consider ... View full abstract»

  • Retransmission scheme for MPEG streams in mission critical multimedia applications

    Publication Year: 1998, Page(s):574 - 580 vol.2
    Cited by:  Papers (2)  |  Patents (14)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (856 KB)

    Since multimedia data are characterized by continuity and massive volume, compression techniques such as MPEG are used for efficient transmission. However, transmission error occurring at a frame tends to be propagated to other frames because MPEG frames cross-reference one another upon presentation. Due to time constraints, it is usual to discard without retransmission the data which have transmi... View full abstract»

    This paper discusses an experimental application which utilises sound (structured musical stimuli) to communicate aspects in the execution of a sorting algorithm. The musical properties investigated are the perception of variable rhythmic patterns (within a list of 13 elements communicated with a sequence of 13 notes in the Diatonic scale), the use of triads whose root position dependent on the lo...

    Distributed computer integrated manufacturing systems (CIM) developed by integrating commercial and off-the-shelf software components, have to fulfil the needs of flexibility required by the end-users and the production line itself. A software architecture designed for a product family and standard interface technologies are a good basis for extendible and scalable systems that can be connected to... View full abstract»

    The main function of a continuous media server is to concurrently stream data from storage to multiple clients over a network. The resulting streams will congest the host CPU bus, reducing access to the system's main memory, which degrades CPU performance. The purpose of this paper is to investigate ways of improving I/O subsystems of continuous media servers. Several improved I/O subsystem archit... View full abstract»

  • Where is knowledge in computational intelligence?: On the reduction of the knowledge level to the level below

    The fundamental conjecture in the present work is that it is actually possible to find effective procedures for reducing the knowledge level to the level below (from natural language to code) and vice versa, if the knowledge is structured. In order to support this conjecture, we prove that this procedure exists and is reversible at least for the case of hierarchical classification and its associat... 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»

    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»

    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»

    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»

    Software reuse demands that existing components must be readily incorporated into new products. These components need to be suitably classified to enable efficient retrieval, and if necessary, adaption. Typically, four schemes have been previously employed: Tree Text, Enumerated, Attribute Value and Faceted classification. The individual classification schemes are unable to solve the problems asso... View full abstract»

    A novel methodology for efficient offline training of multilayer perceptrons (MLPs) is presented. The training is formulated as an optimization problem subject to box-constraints for the weights, so as to enhance the network's generalization capability. An optimization strategy is used combining variable metric, conjugate gradient and no-derivative pattern search methods that renders the training ... View full abstract»
