  1. 1. Consequences of using Quantitative Risk Assessment as a verification tool

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Joey Öström; [2022]
    Keywords : Quantitative Risk Assessment; QRA; performance-based design; verification tool; performance solution; performance requirements; fire risk assessment; residential building; Technology and Engineering;

    Abstract : What are the consequences of using Quantitative risk assessment (QRA) as a verification tool? Performance-based building codes differ from prescriptive-based codes in that they define specific objectives to be met, enabling the building designer to choose which solution to use so long it meets the objectives. This master’s thesis explores the consequences of using QRA as a verification tool in comparison to existing verification methods currently in use in Australia. READ MORE

  2. 2. Free-text Informed Duplicate Detection of COVID-19 Vaccine Adverse Event Reports

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Erik Turesson; [2022]
    Keywords : Duplicate detection; Deduplication; Record linkage; Adverse Event Reports; COVID-19 Vaccines; Uppsala Monitoring Centre; VigiBase; Machine Learning; Gradient Boosted Decision Trees; BERT; Natural Language Processing; Pharmacovigilance; Individual Case Safety Reports;

    Abstract : To increase medicine safety, researchers use adverse event reports to assess causal relationships between drugs and suspected adverse reactions. VigiBase, the world's largest database of such reports, collects data from numerous sources, introducing the risk of several records referring to the same case. READ MORE

  3. 3. Fault Tree Analysis of Quick Clay Slides

    University essay from KTH/Jord- och bergmekanik

    Author : Karl Bäckström; Andreas Linder; [2021]
    Keywords : Quick clay; Quick clay slides; Risk management; Fault tree analysis; Strain-softening behaviour; Kvicklera; Kvicklereskred; Felträdsanalys; Riskhantering; Töjningsmjuknande beteende;

    Abstract : Quick clay slides are quite rare but often leads to major consequences for the society. These type of slides are complex and the true causes leading to a slide is difficult to map since the evidence is destroyed during the slide. Because of this, different theories develop of the causes of the slide based on the same information. READ MORE

  4. 4. Classification Tree Based Algorithms in Studying Predictors for Long-Term Unemployment in Early Adulthood : An Exploratory Analysis Combining Supervised Machine Learning and Administrative Register Data

    University essay from Linköpings universitet/Institutionen för ekonomisk och industriell utvecklingLinköpings universitet/Filosofiska fakulteten

    Author : Sanni Kuikka; [2020]
    Keywords : long-term unemployment; life course research; register data; cohort study; supervised machine learning; CART; random forest;

    Abstract : Unemployment at young age is a negative life event that has been found to have scarring effects for future life outcomes, especially when continuing long-term. Understanding precursors for long-term unemployment in early adulthood is important to be able to target policy interventions in critical junctures in the life course. READ MORE

  5. 5. Comparative study of risk analysis methods from a fire safety perspective - Case study of new underground facilities at CERN

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Frida Olin; Erik Isaksson; [2016]
    Keywords : Risk analysis methods; design fires; event tree analysis; preliminary hazard analysis; What-if; ROGA; Gretener method; NFPA 101; comparative analysis; CERN; technical risk analysis methods; case study; LHC; HL-LHC; complex methods; simplified methods; Technology and Engineering;

    Abstract : This report has investigated which type of risk analysis methods that can be used in an early design phase in a unique facility from a time and quality perspective. Two planned underground facilities for the HL-LHC at CERN have been used as a case study. READ MORE
