  2. 6. Response Matrix Reloaded : for Monte Carlo Simulations in Reactor Physics

    Author : Mickus Ignas; Jan Dufek; Jaakko Leppänen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kärnenergiteknik; Nuclear Engineering;

    Abstract : This thesis investigates Monte Carlo methods applied to criticality and time-dependent problems in reactor physics. Due to their accuracy and flexibility, Monte Carlo methods are considered as a “gold standard” in reactor physics calculations. However, the benefits come at a significant computing cost. READ MORE

  4. 7. Realistic tissue dosimetry models using Monte Carlo simulations. Applications for radionuclide therapies

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

    Abstract : 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. READ MORE

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

    Author : Alexey Siretskiy; Christer Elvingson; Alexander Lyubartsev; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 9. Development of Experimental Brachytherapy Dosimetry Using Monte Carlo Simulations for Detector Characterization

    Author : Vaiva Kaveckyte; Åsa Carlsson Tedgren; Alexandr Malusek; Hamza Benmakhlouf; Jan Seuntjens; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dosimetry; brachytherapy; solid-state detectors; Monte Carlo;

    Abstract : Brachytherapy (BT) is a type of interventional radiotherapy that is advantageous due to high absorbed dose conformity and possibility to deliver high dose in few fractions. It is often used for prostate and gynecological tumors as monotherapy or a boost alongside external beam radiotherapy (EBRT). READ MORE

  7. 10. Development of New Monte Carlo Methods in Reactor Physics : Criticality, Non-Linear Steady-State and Burnup Problems

    Author : Jan Dufek; Jan Wallenius; Waclaw Gudowski; Cheikh Diop; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; reactor physics; fission source; inactive cycles; convergence; burnup; steady-state; criticality; eigenvalue; Nuclear physics; Kärnfysik;

    Abstract : The Monte Carlo method is, practically, the only approach capable of giving detail insight into complex neutron transport problems. In reactor physics, the method has been used mainly for determining the keff in criticality calculations. READ MORE
