  1. 11. Problems in Number Theory related to Mathematical Physics

    Författare :Rikard Olofsson; Pär Kurlberg; Nalini Anantharaman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; number theory; mathetical physics; local zeta functions; cat maps; Beurling primes; MATHEMATICS; MATEMATIK;

    Sammanfattning : This thesis consists of an introduction and four papers. All four papers are devoted to problems in Number Theory. In Paper I, a special class of local ζ-functions is studied. The main theorem states that the functions have all zeros on the line Re(s)=1/2. LÄS MER

  3. 12. Kvinnliga skolledares ledarstil i svensk grundskola

    Författare :Sten-Sture Olofsson; Utbildningsvetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Compitencies; leadership levels; management styles; responsibility and technical rationality; Pedagogy and didactics; women principals; compulsary school; Pedagogik; didaktik;

    Sammanfattning : The purpose of this study was to chart the situation of women principals. By the time the in-vestigation was made the whole amount of women principals in compulsory school was about 16 percent (90/91). Of 235 contacted women, 204 were serving as principals. 173 responded which means 85 percent. LÄS MER

  4. 13. Nanofabrication of Single Electron Transistors and Evaluation of Miniature Biosensors

    Författare :Linda G. M. Olofsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; miniaturization; nanoparticles; impedance; single electron tunneling; biosensors; surface plasmon resonance;

    Sammanfattning : This thesis deals with miniaturization in two different fields: electronics and biosensing. The first part deals with fabrication and measurements of two nanoscale structures - a self-assembled single electron transistor and a (potential) single junction device. LÄS MER

  5. 14. CFD simulation of indoor climate in low energy buildings

    Författare :Daniel Risberg; Thomas Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : In this thesis computational fluid dynamics (CFD) was used for simulation of the indoor climate of low-energy buildings in cold climate. The heat consumption in newly built houses was reduced drastically. LÄS MER

  7. 15. Energy performance of multifamily buildings : building characteristic and user influence

    Författare :Jan-Ulric Sjögren; Thomas Olofsson; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy performance; total heat loss coefficient; gain factor; benchmarking; parameter influence; multivariate method; Building engineering; Byggnadsteknik;

    Sammanfattning : Today many professional property holders use different types of software for monthly energy analyses. The data is however often limited to energy and water use, that is paid for by the property holder. In year 2001, financed by the Swedish Energy Agency, the first steps were taken to create a national web based data base, eNyckeln. LÄS MER
