  1. 1. Modeling, analysis, state and parameter estimation of faulty induction machines

    Författare :Mikael Stocks; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : This thesis covers a broad range of subjects pertaining to induction machines, faulty as well as healthy ones. Firstly, a completely new and unconventional methodology for deriving simplest possible, yet sufficiently accurate, mathematical models for induction machines with general electrical faults is presented.

  3. 2. Neutral and Adaptive Processes Shaping Genetic Variation in Spruce Species

    Författare :Michael Stocks; Martin Lascoux; Renaud Vitalis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spruce; population genetics; adaptation; evolution; picea; approximate bayesian computation; cline;

    Sammanfattning : Population genetic analyses can provide information about both neutral and selective evolutionary processes shaping genetic variation. In this thesis, extensive population genetic methods were used to make inferences about genetic drift and selection in spruce species. LÄS MER

  4. 3. Stator fault detection and parameter estimation in induction machines

    Författare :Mikael Stocks; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : In this licentiate thesis the fascinating area of induction machines is considered. Three different problems are treated, each one of them being more or less unsolved although many researchers around the world have addressed them extensively. LÄS MER

  5. 4. Dynamic Modelling of Communicable and Non-Communicable Diseases

    Författare :Theresa Stocks; Michael Höhle; Tom Britton; Niel Hens; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of two papers dealing with the stochastic dynamic modelling of one communicable and one non-communicable disease respectively. In the first paper we derive a patient- and organ-specific measure for the estimated negative side effects of radiotherapy using a stochastic logistic birth-death process. LÄS MER

  7. 5. Metabolic factors and cancer risk : prospective studies on prostate cancer, colorectal cancer, and cancer overall

    Författare :Tanja Stocks; Pär Stattin; Håkan Jonsson; Annie Lukanova; Jaap Seidell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urology and andrology; Urologi och andrologi; epidemiologi; Epidemiology;

    Sammanfattning : Background: A large number of prospective studies have shown that overweight and diabetes are related to an increased risk of many cancers, including colorectal cancer. In contrast, diabetes has been related to a decreased risk of prostate cancer, and overweight has been related to an increased risk of fatal, but not of incident, prostate cancer. LÄS MER
