  1. 1. On the Adaptive Array Problem

    Författare :Mats Viberg; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direction-of-Arrival; Signal to Noise Ratio; Adaptive array problem; Radio communication system;

    Sammanfattning : By an array we mean a set of coupled sensors, typically antenna elements. The array receives superimposed signals from distant sources. By combining the outputs of the sensors in different ways, one can change the array sensitivity to different Directions-of-Arrival (DOA). LÄS MER

    Författare :Mats Viberg; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subspace fitting; Sensor array processing;

    Sammanfattning : The area of sensor array processing has recently received considerable attention in the litterature. Much interest stems from the potential of applying advanced concepts from signal processing to a variety of real-world problems. LÄS MER

  3. 3. Using Pharmacokinetic and Pharmacodynamic Principles to Evaluate Individualisation of Antibiotic Dosing – Emphasis on Cefuroxime

    Författare :Anders Viberg; Marie Sandström; Otto Cars; Mats Karlsson; Hartmut Derendorf; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacokinetics Pharmacotherapy; Cefuroxime; pharmacokinetics; pharmacodynamics; dosing individualisation; NONMEM; Farmakokinetik Farmakoterapi; PHARMACY; FARMACI;

    Sammanfattning : Cefuroxime is a renally eliminated antibiotic used against a variety of different bacterial infections. The pharmacokinetics (PK) for cefuroxime was studied in 97 hospitalized patients using population analysis. To be able to measure cefuroxime in human serum a new sensitive analytical method was developed using mass spectrometry detection. LÄS MER

  4. 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 :NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; 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; Informations- och kommunikationsteknik; Information and Communication Technology; Informatik; Informatics;

    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.

  5. 5. Barns mångfaldiga språkresurser i mötet med skolan

    Författare :Barbro Hagberg-Persson; Mats Thelander; Monica Axelsson; Åke Viberg; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; heterogeneous groups; polyphonic dialogue; pupil language; small group activities; Swedish; Swedish as a second language; supportive interaction; language development; Bilingualism; Tvåspråkighet; Nordiska språk; Scandinavian Languages;

    Sammanfattning : This dissertation investigates language proficiency in children aged 6–8 in their contact with school – both from an oral and written language perspective. The study is predicated on the current situation in Sweden, where school classes today have a more heterogeneous composition than ever before. LÄS MER
