  1. 1. Toward better image reproduction in offset

    Författare :Emmi Enoksson; Nils Enlund; Ulf Lindqvist; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Images; offset; printing; ICC; color; gamut; profile; calibration; separation; GCR; UCR; characterization; gray balance; Computer science; Datalogi; Media and communication studies; Medie- och kommunikationsvetenskap;

    Sammanfattning : This thesis has focused on color reproduction processes in the graphics field and is based on theoretical research and practical studies. The purpose of this thesis was to investigate how new tools and tools adapted to a specific production set-up can be used to raise awareness regarding the quality and workflow of images and image processing for sheet-fed offset within the graphic industry.

  3. 2. Geant4 Monte Carlo Simulations of the International Space Station Radiation Environment

    Författare :Tore Ersmark; Bengt Lund-Jensen; Lembit Sihver; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space physics; Rymdfysik;

    Sammanfattning : A detailed characterization of the proton and neutron induced radiation environment onboard Columbus and the International Space Station (ISS) has been carried out using the Geant4 Monte Carlo particle transport toolkit. Dose and dose equivalent rates, as well as penetrating particle spectra corresponding to incident trapped protons, GCR protons, SPE protons and cosmic ray albedo neutrons are presented. LÄS MER

  4. 3. The type I and CCR properties for groupoids and inverse semigroups

    Författare :Gabriel Favre; Sven Raum; Fernando Llédo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Representations; groupoids; type I; Operator algebra; unitary representation;

    Sammanfattning : This licentiate thesis consists of one paper about unitary representationtheory of ample groupoids and semigroups together with generalizationsto étale and non-Hausdorff groupoids. In the paper we study algebraically the type I and CCR properties forample Hausdorff groupoids. LÄS MER

  5. 4. Evaluation of strategies to predict and improve early graft survival in clinical islet transplantation

    Författare :Torbjörn Lundgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Islets of Langerhans; clinical islet transplantation; cold storage; outcomes; PET CT; imaging; IBMIR;

    Sammanfattning : Transplantation of the islets of Langerhans as a treatment for type 1 diabetes (T1DM) is a procedure still under development. For the last decade it has been possible to obtain insulin independence by repeated infusions of islets. However, most patients must resume insulin therapy in 2-3 years. LÄS MER
