  1. 1. Decision Analysis in Fire Safety Engineering - Analysing Investments in Fire Safety

    University dissertation from Department of Fire Safety Engineering and Systems Safety, Lund University

    Author : Henrik Tehler; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Safety technology; Byggnadsteknik; Building construction; investment appraisal; epistemic uncertainties; fire safety; Decision analysis; risk analysis; Säkerhetsteknik;

    Abstract : The application of decision analytical methods to the evaluation of investments in fire safety was investigated, particularly with the aim of being able to suggest a method for analysing a specific investment in fire safety for a specific factory. Attention was directed above all at the handling of cases of large epistemic uncertainty regarding both probabilities and utilities, Bayesian decision theory serving as a basis for the development of the method.

  2. 2. Probabilistic Stability Analysis of Underground Mine Excavations

    University dissertation from Luleå tekniska universitet

    Author : Musa Adebayo Idris; Luleå tekniska universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : The creation of underground mine excavation disturbs the original state of the rock mass surrounding the excavation which often leads to instability of the excavation. This poses a threat to the safety of personnel and equipment in and around such excavations. READ MORE

  3. 3. Water and Carbon Balance Modeling: Methods of Uncertainty Analysis

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : John Juston; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; uncertainty analysis; water balance; carbon balance; GLUE; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Abstract : How do additional data of the same and/or different type contribute to reducing model parameter and predictive uncertainties? This was the question addressed with two models – the HBV hydrological water balance model and the ICBM soil carbon balance model – that were used to investigate the usefulness of the Generalized Likelihood Uncertainty Estimation (GLUE) method for calibrations and uncertainty analyses.  The GLUE method is based on threshold screening of Monte Carlo simulations using so-called informal likelihood measures and subjective acceptance criterion.

  4. 4. Influences on toxicological risk assessments

    University dissertation from Stockholm : KTH

    Author : Birgitte Wandall; KTH.; [2007]
    Keywords : HUMANIORA; HUMANITIES; risk assessment; toxicology; values; bias; HUMANITIES and RELIGION History and philosophy subjects Philosophy subjects; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Filosofiämnen;

    Abstract : The aim of this thesis is to characterize and discuss two kinds of influences on the outcome of a toxicological risk assessment. One kind of influence has to do with values and the role played by value-based judgment. Currently, many toxicological risk assessments are characterized by scientific uncertainties. READ MORE

  5. 5. Application of Uncertainty Quantification Techniques to Studies of Wall-Bounded Turbulent Flows

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Saleh Rezaeiravesh; Uppsala universitet.; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty Quantification; Large Eddy Simulation; Wall-Bounded Turbulent Flows; Wall Modeling; OpenFOAM; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : Wall-bounded turbulent flows occur in many engineering applications. The quantities of interest (QoIs) of these flows can be accurately obtained through experimental measurements and scale-resolving numerical approaches, such as large eddy simulation (LES). READ MORE
