  1. 21. How variations of the duration and time to peak of the Chicago Design Storm affect the hydraulic response, as well as the areas contributing to peak runoff, of a synthetic urban catchment area

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Oskar Ahlstedt; [2022]
    Nyckelord :Avrinningsområde; översvämningsmodellering; peak-bidragande område; hydrograf; hyetograf; MIKE 21; regnintensitet; CDS-regn; Chicago Design Storm;

    Sammanfattning : With an expanding urbanization in the world, and thus the expansion of impermeable surfaces, the risk of pluvial floods is an increasing factor that needs to be considered. This, in combination with increasing rain intensities and frequency of rain events indicates a problem both today and for the future. LÄS MER

  3. 22. Direct Signal Interference Suppression and Target Detection for Low-Cost SDR-Based Passive Bistatic Radar

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Oskar Jonsson; [2022]
    Nyckelord :passive radar; ECA; LMS; software-defined radio;

    Sammanfattning : Passive radar is a technology for detection of targets using echoes of existing radio transmitter, such as FM-radio. Since only receivers are needed for operation, a passive radar system has the possibility of being implemented using low-cost hardware. LÄS MER

  4. 23. Hydrodynamic Modelling of Spread of Perfluoroalkyl Octanoic Sulphonate and Perfluoroalkyl Hexanoic Sulphonate in Lake Ekoln

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Prajwol Prajapati; [2022]
    Nyckelord :Hydrodynamic modelling; water quality; PFAS; PFOS; PFHxS; MIKE 3 FM; Ekoln; Fyrisån;

    Sammanfattning : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. LÄS MER

  5. 24. Unemployment Disparities in Southern Africa : Empirical Evidence from Southern African Development Community Member States

    Magister-uppsats, Södertörns högskola/Nationalekonomi

    Författare :Atusaye Zgambo; [2022]
    Nyckelord :Unemployment rate; Southern Africa; SADC; SACU; panel data;

    Sammanfattning : The unemployment rate is one of the most important indicators of economic growth. Reducing unemployment is crucial to ensuring inclusive growth in a country. This paper analyses the relationship between the unemployment rate and other macroeconomic variables in the Southern African Development Community (SADC). LÄS MER

  7. 25. The influence of spatial variations in rain intensity for cloudburst modelling : a case study of the Gävle cloudburst

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Fanny Jeppsson Stahl; [2022]
    Nyckelord :Flood modelling; pluvial flooding; spatial variations in rain intensity; design storms; MIKE 21 Flow Model FM; 2D hydraulic modelling; Skyfallsmodellering; pluviala översvämningar; spatiala variationer i regnintensitet; typregn; MIKE 21 Flow Model FM;

    Sammanfattning : With an intensification of heavy rain events in a changing climate and a rapid urbanization the risk for pluvial flooding is increasing in our societies. Pluvial flooding, which is formed when the rainfall rate exceeds the infiltration or drainage rate, can occur rapidly and cause great damages, large economic losses and possibly risk human lives.
