  1. 1. Modeling contingency infiltration scenarios in MODFLOW : Stockholm Bypass and tunnel induced groundwater drawdown

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

    Författare :Aslan Abdo; [2019]
    Nyckelord :tunnel induced groundwater drawdown; MODFLOW; artificial recharge; land subsidence; grundvattenavsänkning; tunnel inläckage; MODFLOW; infiltration; sättning;

    Sammanfattning : Subsurface constructions, such as tunnels, create hydrogeological challenges in mitigating risk of subsidence due to groundwater drawdown. Presenting readily made precautionary mitigation plans, such as strategically planned artificial recharge applications, can help effectivise the mitigation process. LÄS MER

  2. 2. Towards using microscopic traffic simulations for safety evaluation

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Edgar Tamayo Cascan; [2018]
    Nyckelord :Calibration; Microscopic Traffic Simulation; Multiple Objective; Genetic Algorithm; Traffic Flow; Highway Safety; Kalibrering; Mikroskopisk trafiksimulering; Flera objektiv; Genetisk algoritm; Trafikflöde; Motorvägsäkerhet;

    Sammanfattning : Microscopic traffic simulation has become an important tool to investigate traffic efficiency and road safety. In order to produce meaningful results, incorporated driver behaviour models need to be carefully calibrated to represent real world conditions. LÄS MER

  3. 3. Shafts and rock mass strength : Calibration using numerical models

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Erik Tjäder; [2018]
    Nyckelord :;

    Sammanfattning : Orepasses and ventilation shafts are examples of mine infrastructure that are subjected to increasingstresses as the production in the Kiirunavaara mine moves to deeper levels. Falloutsand damages in these kind of excavations are already occurring and the problem can be expectedto increase in the future. LÄS MER

  4. 4. Sensitivity Analysis in 3D Turbine CFD

    Master-uppsats, KTH/Mekanik

    Författare :Simon Kern; [2017]
    Nyckelord :;

    Sammanfattning : A better understanding of turbine performance and its sensitivity to variations in the inletboundary conditions is crucial in the quest of further improving the efficiency of aero engines.Within the research efforts to reach this goal, a high-pressure turbine test rig has been designedby Rolls-Royce Deutschland in cooperation with the Deutsches Zentrum für Luft- und Raumfahrt(DLR), the German Aerospace Center.

  5. 5. Multi-physical Simulations of High Voltage Circuit Breakers

    Master-uppsats, KTH/Energiteknik

    Författare :Julien POUILLY; [2017]
    Nyckelord :;

    Sammanfattning : This report is the outcome of a 6-month Master’s Thesis carried out at General Electric Grid Solutions in Villeurbanne within the LTDT team in the Circuit Breaker and Bay Development (CB2D) department of the Apparatus Research Center (ARC). It presents both the innovative methodology adopted and the results obtained along the project. LÄS MER
