  1. 1. Dynamic minimum flows in the bypass reach of Juktån : A post-implementation evaluation of the effects on riparian vegetation

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Walter Gezelius Gezelius; [2024]
    Keywords : Restoration; Environmental flows; riparian vegetation;

    Abstract : The purpose of the paper was to evaluate the effects of the restoration efforts in Juktån on the plant species richness and composition, vegetation zonation and soil composition. The restoration involved implementation of a dynamic flow, in addition to hydro-geomorphological alterations. READ MORE

  3. 2. Sustainable Production Patterns for Hydropower Units

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Hannington Kayanja; [2023]
    Keywords : Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

    Abstract : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. READ MORE

  4. 3. Evaluating the feasibility of implementing ecological flows at Fridafors Hydropower plant

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Michelle Eriksson; [2023]
    Keywords : ;

    Abstract : Sweden’s almost 2200 hydropower plants and their attached dams are going to be re-licensed with regards to the new environmental legislations made by the government and EU’s water framework directive. As a solution to restore and improve the health of the Swedish riverine systems, a number of different mitigation measures are suggested. READ MORE

  5. 4. System modelling and evaluation of main battle tank fire precision

    University essay from KTH/Fordonsdynamik

    Author : Viktor Hallbeck; [2021]
    Keywords : Mechanics; MBT; Tracked vehicle; Precision; Mekanik; Stridsvagn; Bandfordon; Precision;

    Abstract : This master thesis describes a study of the main battle tank dynamics in order to investigate the fire precision when a tank is driving in terrain. A model has been developed to simulate the dynamic interaction between the tank's hull and the ground irregularity in MATLAB and SIMULINK through the modelling of the tank's dynamics. READ MORE

  6. 5. Modeling the impact of variable renewable energy sources penetration on supply-demand balance : Analysis of France from 2021 to 2025

    University essay from KTH/Skolan för industriell teknik och management (ITM)
