  1. 1. Simulation of flooding and flood mitigation in the town of Söderköping using HEC-RAS : An investigation of floods and mitigation measures

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

    Författare :Andreas Hoppe; [2024]
    Nyckelord :;

    Sammanfattning : This study examines the effects of flood management systems in an HEC-RAS simulation of recorded discharge in the town of Söderköping in Sweden by using easy-to-access and publicly available hydrological, landcover, and soil data. Two rivers and the precipitation of a chosen area are studied. LÄS MER

  3. 2. Robust Portfolio Optimization

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Anna Mårtensson; Edith Frisk Gärtner; [2023]
    Nyckelord :Mathematics; Optimization and Systems Theory;

    Sammanfattning : The objective of robust portfolio optimization is to find a way to allocate capital to some financial assets such that portfolio return is maximized in the worst-case scenario, which is desirable for investors with a low tolerance for risk. This study aims to apply the robust approach to asset allocation based on 30 of the biggest stocks on the Stockholm Stock Exchange. LÄS MER

    Sammanfattning : Cybersäkerhet är ett konstant växande hot mot organisationer, genom det ständigt ökade digitaliserade samhället, dock finns tecken på att medvetenheten hos organisationer ökar vad gäller cyberattacker och cybersäkerhet. Cyberattacker kan skapa konsekvenser som kan förhindra organisationens verksamhet. LÄS MER

  5. 4. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Nadja Rabizadeh; [2023]
    Nyckelord :CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

    Sammanfattning : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. LÄS MER

  7. 5. Exploring the Feasibility of Using Fire Dynamics Simulator to Improve the Calculation of the Wildfire Available Safe Egress Time

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Alfred El Haddad; [2023]
    Nyckelord :Wildfire; Trigger buffer; WUI; WASET; FDS; QGIS; Level set; WUI evacuation.; Technology and Engineering;

    Sammanfattning : Wildland-Urban Interface (WUI) fires pose a significant threat to public safety and property in areas where urban development encroaches upon natural landscapes. This thesis aims to investigate the effect of smoke from a WUI fire on the tenability conditions of a small village and to establish a worst-case-scenario trigger boundary around it as an improved basis for the WUI available safe egress time (WASET).
