  1. 1. Hur avrinningskoefficienten varierar med återkomsttid - En jämförelse mellan fyra olika områden i Sverige

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Nina Enger; [2024]
    Nyckelord :Runoff coefficient; Return period; Modelling; MIKE ; Floodings; Technology and Engineering;

    Sammanfattning : As climate change progresses, heavy rainfall in Sweden is becoming more frequent and intense, coinciding with an increase in impermeable surfaces in urban areas. This raises the risk of flooding as drainage networks may exceed their capacity due to increased runoff. LÄS MER

  3. 2. BIDRAGSBROTTSLIGHETEN I MALMÖ

    Kandidat-uppsats, Malmö universitet/Institutionen för kriminologi (KR)

    Författare :Amanda Engstrand; Emma Andersson; [2023]
    Nyckelord :Keywords: Crime development; Factors; Situational Action theory; Social welfare crime; Strain theory; Nyckelord: Bidragsbrott; brottsutveckling; faktorer; Situationell handlingsteori; Strainteorin;

    Sammanfattning : Denna studie undersöker bidragsbrottsligheten i Malmö och dess utveckling. Utifrån en kvantitativ ansats med tvärsnittsdesign syftar studien till att belysa utvecklingen av bidragsbrott samt hitta bidragande faktorer till utvecklingsförloppet. LÄS MER

  4. 3. Investigating the effect of grinding method on ore beneficiation behaviour

    Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgi

    Författare :Mellisa Tanaka Mundida; [2023]
    Nyckelord :flotation; grinding; liberation; chalcopyrite; beneficiation; grinding method; selectivity index; VRM; Aitik ore; rodmill; particle shape;

    Sammanfattning : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. LÄS MER

  5. 4. Joinpoint regression analysis of the COVID-19 epidemic curve in Sweden : A descriptive trend analysis of the different regions in Sweden

    Kandidat-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Sebastian Bergwall; Duc Tran; [2023]
    Nyckelord :COVID-19; time series; descriptive analysis; grid search; joinpoint regression;

    Sammanfattning : Since the beginning of the global outbreak, the Swedish Public Health Agency has been closely monitoring the situation regarding COVID-19. Understanding and mapping the behaviour of the COVID-19 epidemic curve in Sweden is of great interest and conducting a descriptive analysis may yield additional important insights. LÄS MER

  7. 5. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Adam Jacobsson Trönndal; [2023]
    Nyckelord :Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

    Sammanfattning : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. LÄS MER
