  1. 1. Trees as heat stress mitigators. The frequency of heat and cold stress in a redevelopment area in Borås, Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Simon Wiklund Wagersten; [2023-06-22]
    Keywords : Cold stress; heat stress; SOLWEIG; thermal comfort; TreePlanter;

    Abstract : As future climate is predicted to generate higher temperatures as well as more frequent extreme weather scenarios, it is essential to plan to mitigate the effects of climate change. In an attempt to mitigate one effect of climate change, this master’s thesis examines both the heat and cold stress at the area Pulsen in Borås Stad, both as the conditions are today, and after the implementation of a new detail plan.

  3. 2. The effect of autocorrelation when performing theapproximated permutation test

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Amerik Schouten; Linus Thor; [2023]
    Keywords : exchangeability assumption; Monte Carlo; temporal autocorrelation; type I error; simulation; re-sampling methods;

    Abstract : In meteorology, permutation tests are a commonly recommended tool because standard paramet-ric methods of inference often is insufficient when analysing weather. Therefore other methodswith less stringent assumptions like permutation testing is used. READ MORE

  4. 3. CFD-modeling of labyrinth weir flood discharge with ice cover

    University essay from KTH/Betongbyggnad

    Author : Erik Isberg; [2023]
    Keywords : ;

    Abstract : A labyrinth weir is a hydraulic structure built with a purpose to increase the discharge capacity compared to linear weirs, while maintaining the same water level upstream. Construction of labyrinth weirs is vital in a future with more unpredictable flows. READ MORE
