  1. 1. Terrain Object recognition and Context Fusion for Decision Support

    Författare :Fredrik Lantz; Erland Jungert; Per Svensson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Fusion; Terrain Elevation Model; Driveability; Context Fusion; Terrain Object Recognition; Computer science; Datalogi;

    Sammanfattning : A laser radar can be used to generate 3D data about the terrain in a very high resolution. The development of new support technologies to analyze these data is critical to the effective and efficient use of these data in decision support systems, due to the large amounts of data that are generated.

  3. 2. Information Acquisition in Data Fusion Systems

    Författare :Ronnie Johansson; KTH; []
    Nyckelord :information acquisition; information fusion; data fusion; sensor management; perception management; game theory; target tracking; mobile sensors;

    Sammanfattning : By purposefully utilising sensors, for instance by a datafusion system, the state of some system-relevant environmentmight be adequately assessed to support decision-making. Theever increasing access to sensors o.ers great opportunities,but alsoincurs grave challenges. As a result of managingmultiple sensors one can, e. LÄS MER

  4. 3. Synchrotron radiation from runaway electrons in plasmas

    Författare :Adam Stahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; runaway electrons; critical electric field; fusion plasma physics; tokamak; synchrotron radiation;

    Sammanfattning : Highly relativistic runaway electrons are of great concern in the area of fusion energy research, since their presence in tokamak plasmas have the potential to hinder the successful and stable operation of the device, and potentially cause severe structural damage. In this thesis, runaway electron generation dynamics is investigated using the newly developed efficient computational tool CODE. LÄS MER

  5. 4. The role of magnetic perturbations in runaway electron and sawtooth dynamics

    Författare :Gergely Papp; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic perturbation; fusion plasma physics; runaway mitigation; sawtooth oscillation; tokamak; runaway electrons;

    Sammanfattning : As the world's fusion energy program is increasingly focused towards burning plasma experiments, it is important to address the remaining theoretical issues. In this thesis we focus on the effect of magnetic perturbations on the radial plasma transport. LÄS MER

  7. 5. Ontology Integration with Non-Violation Check and Context Extraction

    Författare :Dan Wu; Anne Håkansson; Carl-Gustaf Jansson; Paul Johannesson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ontology matching and integration; semantic and pragmatic matching; semantic techniques; context; ontology and rules; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Matching and integrating ontologies has been a desirable technique in areas such as data fusion, knowledge integration, the Semantic Web and the development of advanced services in distributed system. Unfortunately, the heterogeneities of ontologies cause big obstacles in the development of this technique. LÄS MER
