  1. 41. Dose Management in Diagnostic Radiology - application of the DICOM imaging standard and a Monte Carlo dose engine for exposure surveillance

    Författare :Hans-Erik Källman; Anders Ahnesjö; Hilde M. Olerud; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; metadata; DICOM; radiation safety; Monte Carlo; source model; patient model; optimization; justification; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Ionizing radiation is used in diagnostic radiology with a large contribution to the health of the patients. The regulations to limit the detrimental effects, e.g. cancer induction, are based on recommendations from the International Commission on Radiological Protection (ICRP). LÄS MER

  3. 42. Free Energy and Surface Forces in polymer systems: Monte Carlo Simulation Studies

    Författare :Andrei Broukhno; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polyelectrolytes; electrostatic interactions; phase transitions; colloidal stability; surface forces; Monte Carlo simulation; free energy evaluation; polyampholytes; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The thesis is focused on two major subjects: - Calculation of free energy is of great help in the study of any molecular system. The free energy determines phase behaviour of colloids and polymer solutions. It also controls the conformational properties of single macromolecules, e.g. LÄS MER

  4. 43. Sequential Monte Carlo Filters and Integrated Navigation

    Författare :Per-Johan Nordlund; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis we consider recursive Bayesian estimation in general, and sequential Monte Carlo filters in particular, applied to integrated navigation. Based on a large number of simulations of the model, the sequential Monte Carlo filter, also referred to as particle filter, provides an empirical estimate of the full posterior probability density of the system.

  5. 44. Structure Modeling with X-ray Absorption and Reverse Monte Carlo: Applications to Water

    Författare :Mikael Leetmaa; Lars G M Pettersson; John Rehr; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water structure; x-ray absorption; spectroscopy; diffraction; reverse monte carlo; XAS; EXAFS; XANES; RMC; TP-DFT spectrum calculations; Physics; Fysik; kemisk fysik; Chemical Physics;

    Sammanfattning : Water is an important substance. It is part of us, of our environment, and is a fundamental prerequisite for the existence of life as we know it. The structure of water is still, after over 100 years of research on the subject, however under debate. LÄS MER
