  1. 21. Treatment Planning of High Dose-Rate Brachytherapy - Mathematical Modelling and Optimization

    Författare :Björn Morén; Torbjörn Larsson; Åsa Carlsson Tedgren; Bram Gorissen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cancer is a widespread class of diseases that each year affects millions of people. It is mostly treated with chemotherapy, surgery, radiation therapy, or combinations thereof. High doserate (HDR) brachytherapy (BT) is one modality of radiation therapy, which is used to treat for example prostate cancer and gynecologic cancer. In BT, catheters (i. LÄS MER

  3. 22. Computer Vision Based Analysis of Animal Behavior

    Författare :Tobias Palmér; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Datorseende; bildanalys; djurbeteende; neurofysiologi; tillämpningar; refraktion; Computer vision; animal tracking; behavioral analysis; refractions; underwater images; relative pose;

    Sammanfattning : The behavior of animals is commonly studied in medicine and biology. There is a large variation in what animals are studied, in experimental paradigms and purpose.However, many studies on animal behavior have at least one thing in common - it typically involves measuring or studying the kinematics of the animal.

  4. 23. Parameter estimation in heterogeneous catalysis

    Författare :Jonas Sjöblom; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microkinetic modelling; Jacobian; Parameter estimation; Latent Variable models; Design of experiments; heterogeneous catalysis; sensitivity analysis; Experimental design;

    Sammanfattning : The detailed modelling of heterogeneous catalytic systems is challenging due to the unknown nature of new catalytic materials as well as the often required transient nature of the resulting models. Thus, this thesis deals with the methodologies involved in the kinetic modelling of heterogeneous catalysis and in particular NOx reduction systems. LÄS MER

  5. 24. Some Markov Processes in Finance and Kinetics : Markov Processes

    Författare :Mattias Sunden; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CGMY process; Collision kernel; Direct simulation Monte Carlo; Diffusion approximation; Extreme value theory; Feller process; Generalized hyperbolic process; Generalized $z$-process; Infinitesimal generator; Laplace-Beltrami operator; L evy Processes; Long-tailed distribution; Kac equation; Kac model; Markov process; Semigroup; Semi-heavy tailed distirbution; Spectral gap; Subexponential distibrution; Superexponential distribution; Tauberian theorem; Thermostat.; Diffusion approximation;

    Sammanfattning : This thesis consists of four papers. The first two papers treat extremes for L\'evy processes, while papers three and four treat the Kac model with unbounded collision kernel. LÄS MER

  7. 25. Inget klöver utan matematik : En studie av matematik i yrkesutbildning och yrkesliv

    Författare :Karolina Muhrman; Per Andersson; Song-ee Ahn; Viveca Lindberg; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics; vocational education; work life; curriculum; agriculture; curriculum theory; educational code; ethno-mathematics; Matematik; yrkesutbildning; yrkesliv; läroplan; lantbruk; läroplansteori; pedagogisk kod; transformeringsarena; etnomatematik;

    Sammanfattning : Syftet med avhandlingen är att öka förståelsen för aspekter som inverkar på relationen mellan yrkeselevers kunskaper och de kunskaper som behövs i yrkeslivet. Detta görs genom att undersöka olika aktörers perspektiv på yrkeslivets behov av  matematikkunskaper, matematikundervisning på yrkesprogram och utformningen av läroplanen Gy11. LÄS MER
