  1. 1. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies

    Författare :Prabhat Pant; Ru Peng; Johan Moverare; Kjell Simonsson; Thomas Niendorf; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM; Scan strategies; Build orientations;

    Sammanfattning : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. LÄS MER

  3. 2. Acquisition strategies for fat/water separated MRI

    Författare :Henric Rydén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis focuses on new ways to more efficiently acquire the signal for fat/water separated MRI, also known as Dixon methods. In paper I, the concept of dual bandwidths was introduced to improve SNR efficiency by removing dead times in a spin echo PROPELLER sequence. LÄS MER

  4. 3. Optimal strategies and information in foraging theory

    Författare :Emma Sernland; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian foraging; information use; public information; prior information; negative binomial distribution; group foraging; decision-making; information updating; leaving strategy; Ecology; Ekologi; NATURAL SCIENCES; NATURVETENSKAP; Other biology; Övrig biologi; Naturvetenskap; Natural sciences; information use; Bayesian foraging; public information; prior information; negative binomial distribution; group foraging; decision-making; information updating; leaving strategy; Ecology; Ekologi;

    Sammanfattning : In this thesis, I present both theoretical and empirical work where we have studied how humans and animals use information in situations where they need to continually update their information on the density of a resource. We have found that the amount of information, and the way the information is presented, are important factors for how well decisions are adapted to current circumstances. LÄS MER

  5. 4. Novel strategies to increase throughput and differentiate lipid isomers in mass spectrometry imaging : Development of computational tools and complex mass spectrometric methods for nanospray desorption electrospray ionization

    Författare :Johan Lillja; Ingela Lanekoff; Daniel Globisch; Orešič Matej; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; Mass spectrometry imaging; Tandem mass spectrometry; Silver cationization; Mathematical modeling; Lipid; Lipid isomer; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : In this thesis, method development for improved analyte identification and throughput in mass spectrometry imaging (MSI) is discussed. In MSI, the spatial distribution of analytes from a sample is determined and visualized, information about the detected molecules interaction within the sample can thereby the deduced. LÄS MER

  7. 5. Genetic epidemiology of prostate cancer

    Författare :Fredrik Wiklund; Henrik Grönberg; Douglas Easton; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; prostate cancer; epidemiology; genetics; linkage analysis; genome-wide scan; Onkologi; Oncology; Onkologi; Oncology; onkologi;

    Sammanfattning : Prostate cancer is a major health burden throughout the world, yet the etiology of prostate cancer is poorly understood. Evidence has accumulated supporting the existence of a hereditary form of this disease. LÄS MER
