New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    Methodology and Software Prototype for Ontology-Enabled Traceability Mechanisms
    (2006-12-11) Bever, Cari E.; Austin, Mark; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Due to the rapid advancement of technology, industrial-aged systems are being replaced by information-based models through system integration, where hardware and software are combined by a variety of communication means. As engineering systems become progressively complex, the challenge is to fully understand and implement the connectivity relationships among various models of visualization so that catastrophic and expensive failures of engineering systems can be avoided. In order to achieve these connectivity relationships, this project inserts a new notion called "Design Concepts" in the traceability link between the already connected requirements and engineering objects, where rule-checking may be embedded into the design concepts. A software prototype of the Washington, D.C. Metro System has been built to illustrate the feasibility of connectivity between requirements, UML class diagrams and an engineering model. The software makes use of listener-driven events, which are a scalable and efficient method for establishing traceability links and responding to external user events.
