  1. 11. Model on Demand : Algorithms, Analysis and Applications

    Författare :Anders Stenman; Fredrik Gustafsson; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : System identification deals with the problem of estimating models of dynamical systems from observed data. In this thesis, we focus on the identification of nonlinear models, and, in particular, on the situation that occurs when a very large amount of data is available. LÄS MER

  2. 12. Undersökningar av sociovetenskapliga samtal i naturvetenskaplig utbildning

    Författare :Barbro Gustafsson; Lena Fritzén; Per Gerrevall; Anders Jakobsson; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Science education; argumentation; socioscientific; SSI; values; teacher education; democracy; deliberations; meaning-making; Dewey; Habermas; Education; Pedagogik; Education; Pedagogik;

    Sammanfattning : The thesis examines the potential of students’ group discussions in science education in the context of a communicative perspective on democracy and meaning-making. The group discussions in focus are about socioscientific issues (SSI), i.e. controversial and complex issues with scientific as well as sociological aspects. LÄS MER

  3. 13. Development of sensitive EPR dosimetry methods

    Författare :Håkan Gustafsson; Eva Lund; Anders Lund; Dag Rune Olsen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electron paramagnetic resonance EPR ; Formic acids; pharmacology; Lithium; Nickel; Radiometry; Rhodium; Pharmaceutical chemistry; Farmaceutisk kemi;

    Sammanfattning : Electron paramagnetic resonance (EPR) dosimetry using the well established dosimeter material alanine is a generally accepted dosimetric method for measurements of high absorbed doses. Alanine EPR dosimetry is however not sensitive enough for high precision measurements of low (< 5 Gy) absorbed doses using reasonably measurement times and small dosimeters. LÄS MER

  4. 14. Ventricular rotation and the rotation axis : a new concept in cardiac function

    Författare :Ulf Gustafsson; Anders Waldenström; Per Lindqvist; Alan Fraser; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular function; right ventricular function; rotation; twist; rotation axis; transition plane; ischemia; speckle tracking echocardiography; Cardiology; Kardiologi; Cardiology; kardiologi;

    Sammanfattning : Background: The twisting motion of the left ventricle (LV), with clockwise rotation at the base and counter clockwise rotation at the apex during systole, is a vital part of LV function. Even though LV rotation has been studied for decades, the rotation pattern has not been described in detail. LÄS MER

  5. 15. Nanomaterials : respiratory and immunological effects following inhalation of engineered nanoparticles

    Författare :Åsa Gustafsson; Anders Bucht; Thomas Sandström; Johnny Lorentzen; Mikael Adner; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanoparticles; nanomaterials; inhalation; lung; metalloxides; immunologi; Immunology; Toxicology; toxikologi; lungmedicin; Lung Medicine; Occupational and Environmental Medicine; arbets- och miljömedicin; nanopartiklar; nanoparticles; nanotoxikologi; nanotoxicology;

    Sammanfattning : Background Nanotechnology is an important and promising field that can lead to improved environment and human health and contribute to a better social and economic development. Materials in nanoscale have unique physiochemical properties which allow for completely new technical applications. LÄS MER
