  3. 12. Probabilistic treatment planning based on dose coverage : How to quantify and minimize the effects of geometric uncertainties in radiotherapy

    Författare :David Tilly; Anders Ahnesjö; Erik Grusell; Uwe Oelfke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radiotherapy; treatment simulation; probabilistic planning; dose calculation; probabilistic optimization; statistical shape model; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Traditionally, uncertainties are handled by expanding the irradiated volume to ensure target dose coverage to a certain probability. The uncertainties arise from e.g. the uncertainty in positioning of the patient at every fraction, organ motion and in defining the region of interests on the acquired images. LÄS MER

  4. 13. Probabilistic and Experimental Analysis of Heuristic Algorithms for the Multiple-Depot Vehicle-Routing Problem

    Författare :Libertad Tansini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; probabilistic analysis; Multi-Depot Vehicle-Routing problem; heuristics; Time-Windows;

    Sammanfattning : The aim of this thesis is to analyze different heuristic algorithms for solving the Multi-Depot Vehicle-Routing problem (MDVRP) with k depots and n points to be serviced (customers). The objective is to produce a set of service routes which minimizes the total distance traveled. Heuristic approaches are essential since the problem is NP-hard. LÄS MER

  5. 14. Uncertainty, variability and environmental risk analysis

    Författare :Monika Filipsson; Tomas Öberg; Bo Bergbäck; Lars Rosén; Linnéuniversitetet; []
    Nyckelord :Contaminated land; exposure assessment; exposure factors; risk analysis; risk perception; uncertainty; variability; probabilistic risk assessment; NATURAL SCIENCES; NATURVETENSKAP; Miljövetenskap; Environmental Science;

    Sammanfattning : The negative effects of hazardous substances and possible measures that can be taken are evaluated in the environmental risk analysis process, consisting of risk assessment, risk communication and risk management. Uncertainty due to lack of knowledge and natural variability are always present in this process. LÄS MER

  7. 15. A probabilistic approach to risk analysis : a comparison between undesirable indoor events and human sensitivity

    Författare :Katarina Ljungquist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : The main objective of this thesis is to develop a probabilistic procedure similar to the one used in modern design codes for building structures. The purpose of the procedure is to estimate the risk of an unhealthy indoor environment to occur, i.e. LÄS MER
