  • A schemata model of real-time information processing systems

    Creator:
    Szulewski, Paul A.
    Abstract:
    In an attempt to provide a practical means to measure the information processing capacity of a real-time digital processing system a theoretical framework, the Real-Time Schemata, whose basis is a schematic description and a measure of "useful information," is presented. The description applies to processes that would typically be implemented...

  • 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...

  • 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...

  • Attentional flow networks : a real-time adaptive display technique

    Creator:
    Bible, John
    Abstract:
    Graphics resource allocation has often existed on the periphery of graphics research, taking second place to faster or more realistic algorithms for global illumination and modeling. Most research has focused on generating sets of images that best match the effects one might see in photographs. While this approach works well...

  • A real-time digital control system for two hydroelectric power plants

    Creator:
    Hwang, John Dzen
    Abstract:
    The objective of this paper is to describe the design of a real-time system to control two hydroelectric power plants by a digital computer. The two controlling relations are stated as the continuity of water flow and the inequality of power generation requirements. It contains the logical sequence in finding...

  • Hybrid adaptive controller for resource allocation of real-rate multimedia applications

    Creator:
    Vahia, Varin
    Abstract:
    Multimedia applications such as video streaming and Voice over IP are becoming common today with the tremendous growth of the Internet. General purpose operating systems thus are required to support these applications. These multimedia applications have some timing constraints that need to be satisfied for good quality. For example, video...
