  1. 1. Recommendations for Improving the Use of Risk Matrices in Coarse Risk Analyses

    Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Olga Selitski; Esko Roos; [2023]
    Nyckelord :Risk Matrix; Coarse Risk Analysis; Risk Assessment; Probability-Consequence Diagram; Guidance; Guidelines; Recommendations; Improvement.; Technology and Engineering;

    Sammanfattning : Risk matrices are tables with rows representing consequences, and columns representing frequencies. The risk matrix is considered a simple and convenient tool for visualizing risk. However, it has faced critique from the scientific community. LÄS MER

  3. 2. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Lorenzo Contini; [2022]
    Nyckelord :Human behaviour; crowd evacuation; mesoscopic modelling; hydraulic model; large gatherings; fire safety; performance-based design; quantitative risk assessment; consequence analysis; uncertainty analysis; probabilistic modelling; Technology and Engineering;

    Sammanfattning : This study presents a mesoscopic model that predicts pedestrian evacuation in large gatherings with probabilistic methods. The model is based on a coarse network representation of buildings, where occupants are treated at a different scale according to their location. LÄS MER

  4. 3. Post-Wildfire Debris Flows: Mapping and Analysis of Risk Factors in Western North America

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Annejet Tuinstra; [2021]
    Nyckelord :wildfires; debris flows; water repellent soil; North America; skogsbränder; jordskred; vattenavvisande jordlager; Nordamerika;

    Sammanfattning : Climate change is leading to in an increase in frequency and severity of wildfires, which in turn can result in the formation of runoff-initiated post-wildfire debris flows. This type of debris flows is, like most debris flows, triggered by heavy precipitation events. LÄS MER

  5. 4. Probabilistic Analysis of Brake Noise : A Hierarchical Multi-fidelity Statistical Approach

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Sreedhar Venkatesan; Hariprasad Banglore Hanumantha Raju; [2018]
    Nyckelord :Uncertainty and variability; probabilistic analysis; hierarchicalmultifidelity statistical approach; probability of design failure; creep groan;

    Sammanfattning : Computer Aided Engineering driven analysis is gaining grounds in automotive industry. Prediction of brake noise using CAE techniques has become populardue to its overall low cost as compared to physical testing. LÄS MER

  7. 5. Sustainable Aquifer Management in Small Island Developing States : A case study of Mauritius

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Akshay Kowlesser; [2018]
    Nyckelord :groundwater modelling; coastal aquifers; small islands; saltwater intrusion; Mauritius; climate change;

    Sammanfattning : Small Island Developing States (SIDS) are amongst the most vulnerable states in the world. They are subject to a number of stresses including economical, climatic and spatial restraints. This thesis investigates the effects that certain critical ‘stresses’ will have on the groundwater reserves of SIDS. LÄS MER
