  • 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...

  • 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...

  • 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...

  • 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...

  • Multi-instance multi-label learning : algorithms and applications to bird bioacoustics

    Creator:
    Briggs, Forrest
    Abstract:
    We consider the problem of supervised classification of bird species from audio recordings in a real-world acoustic monitoring scenario (i.e. audio data is collected in the field with an omnidirectional microphone, without human supervision). Obtaining better data about bird activity can assist conservation efforts, and improve our understanding of their...

  • Enabling Virtual Globes for A Visual-Auditory User Experience of Spatial Data

    Creator:
    Gune, Aditya N.
    Abstract:
    Geographical datasets are large, complex, and can be difficult for users to navigate and derive meaning from. These datasets, as well as the unique insights derived from them, provide tremendous opportunity for social change -- many of the global challenges humankind is currently facing can benefit from analytics or visualization...

  • Data Classification and Extraction of Weather Reports

    Creator:
    Qin, Rui
    Abstract:
    Severe weather in the United States causes huge insured losses to crop and property frequently.It creates major impact and elicit diverse response in the weather insurance industry. Events like hail, storm, hurricane etc. are more likely to cause catastrophe losses. So it becomes crucial to collect and analyze these extreme...

  • The display function in ALLEGRO

    Creator:
    Ege, Raimund KH
    Abstract:
    Display, which is the function for displaying the schema of the network at the conceptual level, is implemented to enhance the network database system ALLEGRO. To display the schema is one step towards modifiable schemas in the network model. The problem of updating a schema is examined at all three...

  • View based, global design of access structures for relational databases

    Creator:
    Gündem, Taflan İmre
    Abstract:
    In this dissertation we consider the problem of automating the design of access structures for relational database systems. The main considerations are effective and rigorous utilization of the users' usage patterns, global treatment of the whole design and utilizing most of the commonly known access structures. We represent the usage...
