  1. 1. Exponential integrators for stochastic partial differential equations

    Författare :Rikard Anton; David Cohen; Christian Engström; Stig Larsson; Annika Lang; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stochastic partial differential equations; numerical methods; stochastic exponential integrator; strong convergence; trace formulas;

    Sammanfattning : Stochastic partial differential equations (SPDEs) have during the past decades become an important tool for modeling systems which are influenced by randomness. Because of the complex nature of SPDEs, knowledge of efficient numerical methods with good convergence and geometric properties is of considerable importance. LÄS MER

  4. 3. Calcified carotid artery atheromas in panoramic radiographs : diagnostic reliability and association to cardiovascular disease, diabetes and periodontitis

    Författare :Nils Gustafsson; Eva Levring Jäghagen; Jan Ahlqvist; Ulf Näslund; Per Wester; Annika Ekestubbe; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Panoramic radiographs; cardiovascular disease; carotid artery atheromas; diabetes mellitus; oral health; periodontitis; diagnostic accuracy; myocardial infraction; odontologi; Odontology;

    Sammanfattning : Objective: Incidental findings of Calcified Carotid Artery Atheromas (CCAA) on Panoramic Radiographs (PRs) of the jaws can be a risk marker for cardiovascular disease. The objectives for the thesis were to investigate the association between CCAA and 1) Myocardial Infarction (MI), 2) periodontitis, 3) diabetes and 4) estimated cardiovascular risk. LÄS MER
