  1. 1. Neutron Spectroscopy : Instrumentation and Methods for Fusion Plasmas

    Författare :Henrik Sjöstrand; Göran Ericsson; Johan Frenje; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron spectroscopy; plasma diagnostics; fusion power; fusion; plasma heating; MPRu; JET; triton burn-up; ITER; neutron yield; calibration; Fusion; Fusion;

    Sammanfattning : When the heavy hydrogen isotopes deuterium (D) and tritium (T) undergo nuclear fusion large amounts of energy are released. At the Joint European Torus (JET) research is performed on how to harvest this energy. Two of the most important fusion reactions, d+d→3He+n (En = 2.5 MeV) and d+t→4He+n (En = 14 MeV), produce neutrons. LÄS MER

  3. 2. Mind the Gap : Human Decision Making and Information Fusion

    Författare :Maria Nilsson; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Fusion; Decision Making; Distributed Cognition; Decision Support; Information technology; Informationsteknik; Teknik; Technology;

    Sammanfattning : Information fusion, i.e., the automatic integration of information from multiple sources, is an advancing research area which can assist decision makers in enhancing their decisions. Most information fusion research so far has had a technical focus and has paid relatively little attention to human decision making processes. LÄS MER

  4. 3. Predictive Techniques and Methods for Decision Support in Situations with Poor Data Quality

    Författare :Rikard König; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Rule Extraction; Genetic Programming; Uncertainty estimation; Machine Learning; Artificial Neural Networks; Data Mining; Information Fusion; Information technology; Informationsteknik; Teknik; Technology;

    Sammanfattning : Today, decision support systems based on predictive modeling are becoming more common, since organizations often collect more data than decision makers can handle manually. Predictive models are used to find potentially valuable patterns in the data, or to predict the outcome of some event. LÄS MER

  5. 4. Utilizing Diversity and Performance Measures for Ensemble Creation

    Författare :Tuve Löfström; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ensemble Learning; Machine Learning; Diversity; Artificial Neural Networks; Data Mining; Information Fusion; Computer science; Datavetenskap; Teknik; Technology;

    Sammanfattning : An ensemble is a composite model, aggregating multiple base models into one predictive model. An ensemble prediction, consequently, is a function of all included base models. Both theory and a wealth of empirical studies have established that ensembles are generally more accurate than single predictive models. LÄS MER

  7. 5. Large-Scale Information Acquisition for Data and Information Fusion

    Författare :Ronnie Johansson; Henrik I. Christensen; David Nicholson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sensor management; perception management; data fusion; information fusion; large-scale information acquisition; multi-agent coordination protocol; axiomatic bargaining theory; particle filter tracking; pyro-electric infrared sensor; multi-robot system; Computer science; Datalogi;

    Sammanfattning : The purpose of information acquisition for data and information fusion is to provide relevant and timely information. The acquired information is integrated (or fused) to estimate the state of some environment. LÄS MER
