  1. 1. Matter and damping effects in neutrino mixing and oscillations

    Författare :Mattias Blennow; Tommy Ohlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Neutrino oscillations; neutrino mixing; matter effects; damping effects; the day-night effect; solar neutrinos; Teknisk fysik; Engineering physics; Teknisk fysik;

    Sammanfattning : This thesis is devoted to the study of neutrino physics in general and the study of neutrino mixing and oscillations in particular. In the standard model of particle physics, neutrinos are massless, and as a result, they do not mix or oscillate. LÄS MER

  3. 2. Good to use! : Use quality of multi-user applications in the home

    Författare :Mattias Arvola; Kjell Ohlsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software; computer interaction; laidback interaction; face management; ante-use; quality values; quality objectives; Computer science; Datavetenskap;

    Sammanfattning : Traditional models of usability are not sufficient for software in the home, since they are built with office software in mind. Previous research suggest that social issues among other things, separate software in homes from software in offices. LÄS MER

  4. 3. Shades of Use : The Dynamics of Interaction Design for Sociable Use

    Författare :Mattias Arvola; Kjell Ohlsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interaction design; customer meetings; design studios; domestic environments; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : Computers are used in sociable situations, for example during customer meetings. This is seldom recognized in design, which means that computers often become a hindrance in the meeting. LÄS MER

  5. 4. Theoretical and Phenomenological Studies of Neutrino Physics

    Författare :Mattias Blennow; Tommy Ohlsson; Eligio Lisi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neutrino mass; neutrino mixing; neutrino oscillations; matter effects; non-standard effects; the day-night effect; solar neutrinos; accelerator neutrinos; exact solutions; three-flavor effects; large density; neutrino decay; neutrino decoherence; neutrino absorption; non-standard neutrino interactions; seesaw mechanism; stability criteria; leptogenesis; Physics; Fysik;

    Sammanfattning : This thesis is devoted to the theory and phenomenology of neutrino physics. While the standard model of particle physics has been extremely successful, it fails to account for massive neutrinos, which are necessary to describe the observations of neutrino oscillations made by several different experiments.

  7. 5. Machine Learning Survival Models : Performance and Explainability

    Författare :Abdallah Alabdallah; Mattias Ohlsson; Thorsteinn Rögnvaldsson; Sepideh Pashami; Erik Frisk; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Survival Analysis; Explainable Artificial Intelligence; Survival Patterns; Counterfactual Explanations; Evaluation Metrics; Concordance Index;

    Sammanfattning : Survival analysis is an essential statistics and machine learning field in various critical applications like medical research and predictive maintenance. In these domains understanding models' predictions is paramount. LÄS MER
