  1. 6. 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

  2. 7. Improving Fixed Wing UAV Endurance, by Cooperative Autonomous Soaring

    Författare :Klas Andersson; Petter Ögren; Fredrik Bruhn; KTH; []

  3. 8. Perceptually motivated speech recognition and mispronunciation detection

    Författare :Christos Koniaris; Olov Engwall; Martin Cooke; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; feature extraction; feature selection; auditory models; MFCCs; speech recognition; distortion measures; perturbation analysis; psychoacoustics; human perception; sensitivity matrix; pronunciation error detection; phoneme; second language; perceptual assessment;

    Sammanfattning : This doctoral thesis is the result of a research effort performed in two fields of speech technology, i.e., speech recognition and mispronunciation detection. Although the two areas are clearly distinguishable, the proposed approaches share a common hypothesis based on psychoacoustic processing of speech signals. LÄS MER

  4. 9. Information Technology Alignment : The Role of Organisational Structure

    Författare :Gideon Mekonnen Jonathan; Lazar Rusu; Erik Perjons; Björn Johansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer and Systems Sciences; data- och systemvetenskap; informationssystem; Information Systems;

    Sammanfattning : Information technology (IT) alignment studies which focus on conceptual debates have left little room for studies investigating practical issues such as organisational structure. On the other hand, the attention paid to private and commercial organisations has resulted in findings that might not apply to public organisations. LÄS MER

    Sammanfattning : This dissertation reports on an investigation into how digital tools are used, negotiated and given meaning in Swedish pre-school teacher education. The overall aim has been to create a deeper understanding of how students’ information literacies are enacted when digital tools are used and appropriated in the daily life at a pre-school teacher education, in relation to conceptions of the digitalisation of teacher education in national policy.
