  1. 11. On the Robustness of Statistical Models: Entropy-based Regularisation and Sensitivity of Boolean Deep Neural Networks

    Författare :Olof Zetterqvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep neural networks; Noise stability; Noisy labels; Noise sensitivity; Boolean functions; Regularisation;

    Sammanfattning : Models like deep neural networks are known to be sensitive towards many different aspects of noise. Unfortunately, due to the black-box nature of these models, it is in general not known why this is the case. Here, we analyse and attack these problems from three different perspectives. LÄS MER

  3. 12. Engineering Software for Resilient Cyber-Physical Systems

    Författare :Ricardo Diniz Caldas; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Designing, implementing, and verifying resilient cyber-physical systems is challenging. Resilience is the ability to provide the required capability when facing adversity. LÄS MER

  4. 13. Tracking Theory for Preventive Safety Systems

    Författare :Lars Danielsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle tracking; sensor data fusion; automotive; active safety systems; sensor models; warning integration; motion models; fusion strategies; human machine interface; preventive safety systems;

    Sammanfattning : Preventive safety systems rely on accurate information from a sensing system regarding the current traffic situation to make decision whether to inform, warn or intervene to avoid an impeding collision or to mitigate its consequences. This thesis mainly considers tracking algorithms to enhance these systems through making the best use of the information supplied by on-vehicle sensors, such as radar and vision sensors. LÄS MER

  5. 14. Overload Control and Performance Evaluation of Web Servers

    Författare :Mikael Andersson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system; numerisk analys; Datalogi; control; systems; numerical analysis; Computer science; Content Adaptation; Admission Control; Overload Control; Web servers; Performance modeling; kontroll; Technological sciences; Teknik; Systems engineering; computer technology; Data- och systemvetenskap; Telecommunication engineering; Telekommunikationsteknik;

    Sammanfattning : We are increasingly dependent on Internet as a large aspect of our daily life is now handled via online applications. Recent years we have seen several large-scale crises. This has made crisis-related research on Internet applications important. LÄS MER

  7. 15. Beställarkompetens vid upphandling och utveckling av IT : Om kompetensframväxt i skuggan av kunskapsfragmentering

    Författare :Michel Thomsen; Sven Carlsson; Thomas Kalling; Karin Axelsson; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; knowledge; fragmentation; systems development; competence; systems acquisition; beställarkompetens; Informatics; Informatik; fragmentation; knowledge; systems development; competence; systems acquisition; beställarkompetens;

    Sammanfattning : Ever since IT started to become important and strategic assets in organizational practices, systems acquisitions have been a challenging and complex endeavor. There are seemingly never ending reports of unsuccessful IT acquisitions and lack of systems acquisition competence (beställarkompetens in Swedish). LÄS MER
