  1. 1. Inference of Effective Pairwise Relations for Data Processing

    Författare :Fazeleh Sadat Hoseini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Motion trajectory clustering; Concurrent programming; Representation Learning; Pairwise Relations; Memory Efficiency; Minimax Distance; Performance Modeling;

    Sammanfattning : In various data science and artificial intelligence areas, representation learning is a performance-critical step. While different representation learning methods can detect different descriptive and latent features, many representation learning methods reflect on pairwise relations. LÄS MER

    Sammanfattning : In recent decades, Rwanda has been affected by the loss and fragmentation of natural habitats for native species of animals and plants. As a consequence, landscape connectivity—i.e. LÄS MER

  4. 3. Effective Charges Near 56Ni and Production of Anti-Nuclei Studied with Heavy-Ion Reactions

    Författare :Rickard du Rietz; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RDDS; Nuclear physics; Kärnfysik; PHENIX; RHIC; mirror nuclei; shell-model calculations; fusion-evaporation reactions; effective charges; anti-deuteron; Heavy-ion reactions; Fysicumarkivet A:000;

    Sammanfattning : This thesis presents the research performed within two different research groups using heavy-ion induced nuclear reactions. They offer the opportunity to investigate different properties of nuclear matter. The results are based on measurements using a variety of different experimental techniques. LÄS MER

  5. 4. Design and use of mobile technology in distance language education : Matching learning practices with technologies-in-practice

    Författare :Olga Viberg; Åke Grönlund; Mats Tegmark; Annika Andersson; Victor Kaptelinin; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; online distance education; mobile learning; mobile-assisted language learning; information systems artefact; design science research; learning practices; structuration; self-regulation; technology-in-practice; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys; Informatik; Informations- och kommunikationsteknik;

    Sammanfattning : This thesis focuses on the adaptation of formal education to people’s technology- use patterns, theirtechnology-in-practice, where the ubiquitous use of mobile technologies is central. The research question is: How can language learning practices occuring in informal learning environments be effectively integrated with formal education through the use of mobile technology? The study investigates the technical, pedagogical, social and cultural challenges involved in a design science approach.

  7. 5. Flexibel utbildning - för vem? : Framgångsfaktorer i en universitetskurs

    Författare :Ulf Olsson; Bo Dahlin; Hugo Wikström; Yngve Nordkvelle; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Open distance learning; Prediction of study success; Study approaches; ; Distance education; Flexible learning; Higher education; Learning strategies; Distansutbildning; Flexibelt lärande; Flexibel utbildning; Förutsägelse av studieresultat; Högre utbildning; Studiemönster; ; Education; Pedagogik; Pedagogik; Pedagogy;

    Sammanfattning : Open and flexible learning can offer the prospective student a smorgasbord of possible learning activities. This study will investigate if this form of education really suits all students through an examination of relevant factors such as learning process expectations, attendance motives, study approaches (Biggs SPQ), communication initiative, expectation-based study and, finally, background variables such as socioeconomic status.
