  • An experimental string processing extension to Pascal

    Creator:
    Weems, Charles Chilton
    Abstract:
    The need for and problems related to string processing are discussed and a definition of the term "string" is derived. A brief review of some existing string processing systems leads to the presentation of a design for a string processing extension to the programming language Pascal. A rationale for the...

  • SES: a real time message oriented system for easy intertask communication

    Creator:
    Saedi-Faez, Sheida
    Abstract:
    In process control systems where an entire process is being controlled by a computer, the component tasks of the system have to be monitored. An efficient message oriented environment could be an important factor in the optimization of such systems. In this paper we discuss the design of a real...

  • Robustness in a distributed storage server for engineering design data with versions

    Creator:
    Ecklund, Denise J.
    Abstract:
    Traditional database management systems have been deemed unsuitable for use in the Computer Aided Engineering environment Object-oriented data models with project management features have been proposed as an alternative. The Distributed Hypothetical Storage System is intended to serve as the underlying storage mechanism for an object-oriented data model. The storage...

  • Design and analysis of hard real-time systems

    Creator:
    Zhu, Jiang
    Abstract:
    First, we study hard real-time scheduling problems where each task is defined by a four tuple (r, c, p, d): r being its release time, c computation time, p period, and d deadline. The question is whether all tasks can meet their deadlines on one processor. If not, how many...

  • Algorithms for string matching with applications in molecular biology

    Creator:
    Holloway, James Lee
    Abstract:
    As the volume of genetic sequence data increases due to improved sequencing techniques and increased interest, the computational tools available to analyze the data are becoming inadequate. This thesis seeks to improve a few of the computational methods available to access and analyze data in the genetic sequence databases. The...

  • Optimization of machine allocation in RingLeader

    Creator:
    King, Jonathan B.
    Abstract:
    Many different types of distributed batch scheduling systems have been developed in the last decade to take advantage of the decentralization of computers and the enormous investments that many companies and educational institutions have in desktop workstations. Based on the premise that the majority of desktop workstations are significantly underutilized,...

  • On resource placements and fault-tolerant broadcasting in toroidal networks

    Creator:
    AlMohammad, Bader Fahed AlBedaiwi
    Abstract:
    Parallel computers are classified into: Multiprocessors, and multicomputers. A multiprocessor system usually has a shared memory through which its processors can communicate. On the other hand, the processors of a multicomputer system communicate by message passing through an interconnection network. A widely used class of interconnection networks is the toroidal...

  • A factoring approach for probabilistic inference in belief networks

    Creator:
    Li, Zhaoyu
    Abstract:
    Reasoning about any realistic domain always involves a degree of uncertainty. Probabilistic inference in belief networks is one effective way of reasoning under uncertainty. Efficiency is critical in applying this technique, and many researchers have been working on this topic. This thesis is the report of our research in this...

  • Knowledge-based decision model construction for hierarchical diagnosis and repair

    Creator:
    Yuan, Soe-Tsyr
    Abstract:
    Knowledge-Based Model Construction (KBMC) has generated a lot of attention due to its importance as a technique for generating probabilistic or decision-theoretic models whose range of applicability in AI has been vastly increased. However, no one has tried to analyze the essential issues in KBMC, to determine if there exists...

  • Automatic scheduling and dynamic load sharing of parallel computations on heterogeneous workstation clusters

    Creator:
    Jacob, Joseph, 1971-
    Abstract:
    Parallel computing on heterogeneous workstation clusters has proved to be a very efficient use of available resources, increasing their overall utilization. However, for it to be a viable alternative to expensive, dedicated parallel machines, a number of key issues need to be resolved. One of the major challenges of heterogeneous...
