  1. 1. Kontroll av beroende. Substitutionsbehandlingens logik, praktik och semantik

    Författare :Frida Petersson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; drug addiction; client construction; methadone treatment; accounts; disciplinary power.;

    Sammanfattning : This thesis concerns maintenance treatment with methadone or buprenorhine in Sweden. The general aim has been to contribute to an understanding of the everyday practice of maintenance treatment, how power is exercised and how clients are constructed in a local, outpatient treatment context.

  3. 2. Asymptotic Expansions for Perturbed Discrete Time Renewal Equations

    Författare :Mikael Petersson; Dmitrii Silvestrov; Ola Hössjer; Henrik Hult; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewal equation; Perturbation; Asymptotic expansion; Regenerative process; Quasi-stationary distribution; Risk process; Ruin probability;

    Sammanfattning : In this thesis we study the asymptotic behaviour of the solution of a discrete time renewal equation depending on a small perturbation parameter. In particular, we construct asymptotic expansions for the solution of the renewal equation and related quantities. LÄS MER

  4. 3. A Nonlinear Optimization Approach to H2-Optimal Modeling and Control

    Författare :Daniel Petersson; Johan Löfberg; Lennart Ljung; Roland Toth; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model reduction; LPV system; linear parameter varying; controller; control synthesis; H2; H2-norm; nonlinear optimization;

    Sammanfattning : Mathematical models of physical systems are pervasive in engineering. These models can be used to analyze properties of the system, to simulate the system, or synthesize controllers. However, many of these models are too complex or too large for standard analysis and synthesis methods to be applicable. LÄS MER

  5. 4. Fast and Accurate 4D Flow MRI for Cardiovascular Blood Flow Assessment

    Författare :Sven Petersson; Tino Ebbers; Oliver Wieben; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The study of blood flow is essential in understanding the physiology and pathophysiology of the cardiovascular system. Small disturbances of the blood flow may over time evolve and contribute to cardiovascular pathology. LÄS MER

  7. 5. Pharmacovigilance : spontaneous reporting in health care

    Författare :Elisabet Ekman; Göran Petersson; Susanna Wallerstedt; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacovigilance; adverse drug reaction; spontaneous reporting; nurses; physicians; attitudes; torsades de pointes; erectile dysfunction; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : Pharmacovigilance in healthcare is essential for safe drug treatment. Spontaneous reporting is the most common source of information in the context of implementing label changes and taking a drug off the market. However, underreporting is found to be very prevalent. LÄS MER
