  1. 1. Some Problems in Quantified Security

    Författare :Vilhelm Verendel; Chalmers University of Technology; []
    Nyckelord :computer security; quantified risk; quantified security; risk behavior; operational risk; security metrics; information security; survey; quantitative models; decision-making; risk perception;

    Sammanfattning : This thesis contains work related to quantitative representation and analysis of computer and information security. The ability to accurately describe security using quantitative methods could offer better control and evaluation of security in operational settings. LÄS MER

  2. 2. Cancer Risk Assessment of Glycidol : Evaluation of a Multiplicative Risk Model for Genotoxic Compounds

    Författare :Jenny Aasa; Margareta Törnqvist; Elaine M. Faustman; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; glycidol; 3-monochloropropane-1; 2-diol 3-MCPD ; genotoxicity; mutations; micronuclei; hemoglobin adducts; in vivo dose; multiplicative risk model; cancer risk assessment; human cancer risk; Environmental Chemistry; miljökemi;

    Sammanfattning : Humans are exposed to chemical compounds in everyday life, both from the environment and from endogenous processes. Some compounds constitute a risk for cancer development. One such compound is glycidol, which is genotoxic and an animal carcinogen. It is the model compound of this work, partly due to its presence in food. LÄS MER

  3. 3. Accident Risk and Environmental Assessment : Development of an Assessment Guideline with Examination in Northern Scandinavia

    Författare :Markus Lundkvist; Lennart Strömquist; Christer Jonasson; Rolf Nyberg; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Geography; accident; risk; hazard; environmental assessment; geomorphology; railway; road; avalanche; debris flow; rock fall; slush flow; torrent; moose; reindeer; environmental impact assessment; proposal alternatives; Kiruna; Narvik; Geografi; Other earth sciences; Övrig geovetenskap;

    Sammanfattning : In environmental impact assessment (EIA), accident risk should be considered as one impact. However, few studies have compared assessed risk levels with documented accidents. There is thus a need for assessing accuracy of risk assessment methodologies. LÄS MER

  4. 4. From data to decision - learning by probabilistic risk analysis of biological invasions

    Författare :Ullrika Sahlin; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; probabilistic models; establishment success; prediction; forecasting; uncertainty; risk; invasive species; Bayesian methods;

    Sammanfattning : Predicting an uncertain future with uncertain knowledge is a challenge. The success of efforts to preserve biodiversity, to maintain biosecurity and to reduce a negative impact from climate change, depend on scientifically based predictions of future events. LÄS MER

  5. 5. Uncertainty and Risk Analysis in Fire Safety Engineering

    Författare :Håkan Frantzich; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event tree; fire engineering design; reliability index; FOSM; Monte Carlo simulation; Risk analysis; uncertainty analysis; response surface.; Technological sciences; Teknik;

    Sammanfattning : Two Quantitative Risk Analysis (QRA) methods are presented which can be used to quantify the risk to occupants in, for example, a building in which a fire has broken out. The extended QRA considers the inherent uncertainty in the variables explicitly. LÄS MER
