1. 1. Fish Friendly Turbines forDownstream Migration : Literature review and case studies

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Signe Rosenblad; [2023]
   Keywords : Downstream passage solutions; downstream migration of fish; small-scale hydropower; eel; trout; Nedströms passagelösningar; nedströms vandring av fisk; småskalig vattenkraft; ål; öring;

   Abstract : As the energy consumption is constantly increasing, the demand of renewable energy is increasing too. Thirtythree percent of the renewable energy production in Europe constitutes of hydropower. Hydropower is animportant energy source as it has stabilizing and storing functions, but it heavily affects biodiversity. READ MORE

3. 2. Slippery as an Eel. An analysis of the European Union's Eel Regulation Framework

   University essay from Lunds universitet/Statsvetenskapliga institutionen

   Author : Erica Allison; [2023]
   Keywords : eel; EU; legitimacy; posthumanism; stakeholders; Law and Political Science;

   Abstract : This thesis uses an evaluative approach to analyse the European Union’s Eel Regulation Framework (ERF). By using theories on both legitimacy and posthumanism, the aim of the study is to answer the question of in which ways the ERF can be considered legitimate with both human and non-human stakeholders in mind.

4. 3. Closed-Loop Control of a 3D Printed Soft Actuator with Soft Position Sensors

   University essay from KTH/Mekatronik

   Author : Jakob Jansson; Mikael Sjöberg; [2021]
   Keywords : Soft Actuators; 3D Printing; Closed-Loop Control; Strain Sensor; Soft Gripper; Mjuka Ställdon; 3D-Skrivning; Återkopplad Kontroll; Töjningssensor; Mjukt Gripdon;

   Abstract : This thesis performs closed-loop control of a 3D printed soft bending actuator with feedback from a 3D printed strain sensor. This process utilizes the Finite Element Method (FEM) to design a bellow type pneumatic bending actuator that can handle pressures up to 4 bar. READ MORE

   Abstract : This project was performed on assigment of Vattenfall R&D in Älvkarleby. The project was a first step in evaluating whether bubble curtains with vertical tubes could be suitable for diverting fish from hydro power intakes into fish passages. READ MORE

6. 5. Natural migration barriers for fish by hydropower plants : methods to assess historic passability. Case studies of migration barriers

   University essay from SLU/Dept. Of Aquatic Resources

   Author : Johansson Anders; [2016]
   Keywords : natural migration barriers; historic passablility; reference connectivity; connectivity; fish; brown trout; eel; hydropower;

   Abstract : Is it necessary to build fishways at all artificial migration barriers to restore and sustain bio-diversity? Hydropower plants have often been built at places where a difference in height has been used to gain more power, leading to the hypothesis that many hydropower dams have been built at natural migration barriers. How are Swedish running waters (not large rivers) assessed with respect to historical passability for fish at natural migration barriers and dams? How does one study a specific location with respect to the historical passability for different fish species? The methodologies that are evaluated in this thesis are relevant and specific information from a habitat mapping from Värmland County, where 2 903 km waterways already have been surveyed. READ MORE
