  1. 11. Monte Carlo Simulations of Homogeneous and Inhomogeneous Transport in Silicon Carbide

    Författare :Mats Hjelm; KTH; []
    Nyckelord :simulation; Monte Carlo; SiC; charge transport; MOSFET; MESFET;

    Sammanfattning : The importance of simulation is increasing in the researchon semiconductor devices and materials. Simulations are used toexplore the characteristics of novel devices as well asproperties of the semiconductor materials that are underinvestigation, i.e. generally materials where the knowledge isinsufficient.

  3. 12. Realistic tissue dosimetry models using Monte Carlo simulations. Applications for radionuclide therapies

    Författare :Erik Larsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; internal dosimetry; radionuclide therapy; Monte Carlo; small scale dosimetry;

    Sammanfattning : Radionuclide therapy (RNT) is a generic term for treatment modalities that use a radionuclide labeled to a target-specific molecule. This so-called radiopharmaceutical accumulates in the target, where the ionizing radiation damages the cells. At sufficient levels of radiation, the cells cannot repair themselves. LÄS MER

  4. 13. Studies of clinical proton dosimetry using Monte Carlo simulation and experimental techniques

    Författare :Joakim Medin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proton dosimetry; Proton stopping power; Monte Carlo; Proton stopping-power ratios; Ionization chamber calibration; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : The present work aims at improving clinical proton dosimetry based on ionization chambers, and to bring its state of development closer to the corresponding status of conventional photon and electron dosimetry. In order to accomplish this, both theoretical and experimental methods have been used. LÄS MER

  5. 14. Monte Carlo Simulations of the Equilibrium Properties of Semi-stiff Polymer Chains : Efficient Sampling from Compact to Extended Structures

    Författare :Alexey Siretskiy; Christer Elvingson; Alexander Lyubartsev; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymers; equilibrium properties; statistical mechanics; computer simulation; Monte Carlo; Wang-Landau; compact structures; parallel computations; Physical chemistry; Fysikalisk kemi; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : Polymers is a class of molecules which can have many different structures due to a large number of degrees of freedom. Many biopolymers, e.g. DNA, but also synthetic macromolecules have special structural features due to their backbone stiffness. LÄS MER

  7. 15. Monte Carlo Results for Bootstrap Tests in Systems with Integrated-Cointegrated Variables

    Författare :Panagiotis Mantalos; Statistiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; programming; operations research; Statistics; Granger-causality; Monte Carlo; Cointegration; Bootstrap; Statistik; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : When we study the properties of a test procedure, two aspects are of prime importance. Firstly, we wish to know if the actual size of the test (i.e., the probability of rejecting the null when true) is close to the nominal size (used for calculating the critical values). LÄS MER
