  1. 1. Querying RDF Schema Views of Relational Databases

    Författare :Johan Petrini; Tore Risch; Larry Kerschberg; Uppsala universitet; []
    Nyckelord :query processing; partial evaluation; rdf; rdf schema; view; relational databases; semantic web;

    Sammanfattning : The amount of data found on the web today and its lack of semantics makes it increasingly harder to retrieve a particular piece of information. With the Resource Description Framework (RDF) every piece of information can be annotated with properties describing its semantics. LÄS MER

  3. 2. Relations in Dependent Type Theory

    Författare :Carlos Gonzalía; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; formalized mathematics; relational systems; category theory; programming logics; constructive type theory; logical frameworks; relational database model;

    Sammanfattning : This thesis investigates how to express and reason about relational concepts and methods inside the constructive logical framework of Martin-Löf's monomorphic type theory. We cover several areas where the notion of relation is central, and show how to formalize the basic concepts of each area. LÄS MER

  4. 3. Framework For Structuring Information For Environmental Management Of Industrial Systems

    Författare :Raul Carlson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Life cycle assessment LCA ; data format; characterisation; weighting; information structuring; Design for Environment DfE ; indicator; sustainable development; industrial environmental information systems; database;

    Sammanfattning : This thesis addresses information structuring for reducing cost, facilitate understandability, increase relevance and improve quality of environmental information. The research is based in experience, practical results and syntheses from three different but related research and development projects conducted between 1994 and 2004. LÄS MER

  5. 4. Digital product catalogues : an evaluation of presentation and visualization techniques

    Författare :Anders Follin; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photorealistic visualization; three-dimensional modeling; Advanced digital product catalogue; computer animation; integrated visualization information; relational database;

    Sammanfattning : This licentiate thesis concerns advanced digital product catalogues, with the main focus on product presentation. A computer based digital product catalogue opens new possibilities for advanced product presentation and integration into the existing compute environment. Several new possibilities for product presentation become available. LÄS MER

  7. 5. Data management in control applications : a proposal based on active database systems

    Författare :Esa Falkenroth; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Active database management systems can provide general solutions to data management problems in control applications. This thesis describes how traditional control algorithms and high-level operations in a control system can be combined by using an embedded active object-relational database management system as middleware.
