  1. 1. Between the Probe and the Pump : An experimental study on cardiac performance analysis based on Echocardiography, tissue and laser Doppler

    Författare :Laila Hübbert; Birgitta Janerot-Sjöberg; Ulf Dahlström; Sven-Erik Ricksten; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Echocardiography is an ultrasound-based bedside, non-invasive and easily available cardiac diagnostic technique visualising the heart’s morphology and function. Quantification of cardiac wall motion can be measured with the tissue Doppler Imaging (TDI) modality which provides in humans a high diagnostic capacity to differentiate healthy from diseased myocardium with reduced function.

    Sammanfattning : Background: Heart Failure is a serious condition with consequences not only for the individual patient but also for the society with a 5-year mortality rate of 45-60%, and a substantial economic burden. The estimated prevalence in Sweden is 2.2% and the age adjusted prevalence increases with higher age. LÄS MER

  4. 3. Global radial basis function collocation methods for PDEs

    Författare :Ulrika Sundin; Elisabeth Larsson; Simon Hubbert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Radial basis function (RBF) methods are meshfree, i.e., they can operate on unstructured node sets. Because the only geometric information required is the pairwise distance between the node points, these methods are highly flexible with respect to the geometry of the computational domain. LÄS MER

  5. 4. Petroleum Production and Exploration : Approaching the End of Cheap Oil with Bottom-Up Modeling

    Författare :Kristofer Jakobsson; Kjell Aleklett; Roger Bezdek; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The theme of this thesis is the depletion of petroleum (crude oil and natural gas). Are there reasons to be concerned about an ‘end of cheap oil’ in the near future? There is a lively debate regarding this issue. The debate is sometimes described as a clash of ‘concerned’ natural scientists and ‘unconcerned’ economists. LÄS MER
