  1. 1. Harmonisation of 3D geodata : a prerequisite for a digital information flow for applications in the planning and building sector

    Författare :Helen Eriksson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data harmonisation; schema extension; 3D buildings; 3D city models; GeoBIM; lifecycle and version management; emporal information; user requirements; Guidelines; Hydrography;

    Sammanfattning : Data harmonisation is a prerequisite for smart cities, for a more efficient information flow in the planning and building process and for many applications in the urban environment. Ideally, data harmonisation will result in a digital information flow that include information from the whole lifecycle of a feature, for example for buildings, roads and tunnels. LÄS MER

  3. 2. Mapping and integration of schema representations of component specefications

    Författare :Guy Davies; Love Ekenberg; Hamid Fujita; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; specification; first order logic; verification; service integration; conceptual modeling; conflict; shema dynamics; Datavetenskap; Computer science; Datavetenskap;

    Sammanfattning : Specification for process oriented applications tends to use languages that suffer from infinite, intractable or unpredictably irregular state spaces that thwart exhaustive searches by verification heuristics. However, conceptual schemas based on FOL, offer techniques for both integrating and verifying specifications in finite spaces. LÄS MER

  4. 3. Scalable Preservation, Reconstruction, and Querying of Databases in terms of Semantic Web Representations

    Författare :Silvia Stefanova; Tore Risch; Stefan Decker; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RDF; RDFS; RDF view; SPARQL; SPARQL query processing; rewrite optimization; Topic Maps; querying of RDF views; archive relational databases; reconstruct archived databases; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : This Thesis addresses how Semantic Web representations, in particular RDF, can enable flexible and scalable preservation, recreation, and querying of databases.An approach has been developed for selective scalable long-term archival of relational databases (RDBs) as RDF, implemented in the SAQ (Semantic Archive and Query) system.

  5. 4. An architecture and a knowledge representation model for expert critiquing systems

    Författare :Jonni Harrius; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aim of an expert critiquing system (ECS) is to act as an assistant in a problem-solving situation. Once a user has presented a tentative solution to a given problem, the ECS reviews the proposed solution and then provides a critique — an evaluation of the solution. LÄS MER

  7. 5. Design and Modelling of a Parallel Data Server for Telecom Applications

    Författare :Mikael Ronström; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Telecom databases are databases used in the operation of the telecom network and as parts of applications in the telecom network. The first telecom databases were Service Control Points (SCP) in intelligent Networks. These provided mostly number translations for various sevices, such as Freephone. LÄS MER
