  4. 3. On Long Proofs of Simple Truths

    Författare :Kilian Risse; Per Austrin; Johan Håstad; Jakob Nordström; Benjamin Rossman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational Complexity; Lower Bounds; Proof Complexity; Datalogi; Computer Science;

    Sammanfattning : Propositional proof complexity is the study of certificates of infeasibility. In this thesis we consider several proof systems with limited deductive ability and unconditionally show that they require long refutations of the feasibility of certain Boolean formulas. LÄS MER

  5. 4. Automatic segmentation in CMR - Development and validation of algorithms for left ventricular function, myocardium at risk and myocardial infarction

    Författare :Jane Tufvesson; Lund Klinisk fysiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic segmentation; cardiovascular magnetic resonance; validation; Expectation Maximization; freely available software; myocardial infarction;

    Sammanfattning : In this thesis four new algorithms are presented for automatic segmentation in cardiovascular magnetic resonance (CMR); automatic segmentation of the left ventricle, myocardial infarction, and myocardium at risk in two different image types. All four algorithms were implemented in freely available software for image analysis and were validated against reference delineations with a low bias and high regional agreement. LÄS MER

  7. 5. Crossflow Microfiltration of particle Suspensions - The influence of hydrodynamics and physico-chemical interactions

    Författare :Ingmar Harald Huisman; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; ceramic membranes; shear-induced diffusion; crossflow microfiltration; silica particles; zeta potential; Livsmedelsteknik;

    Sammanfattning : Crossflow microfiltration is a technique to separate suspended particles (or cells or droplets) from liquids by use of a membrane that is permeable for the liquid but impermeable for the particles. The permeate flow drives particles to the membrane surface, where they may be deposited and form a fouling layer. LÄS MER
