  1. 11. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

    University essay from Uppsala universitet/Datalogi

    Author : Lovisa Olsson; Julia Hellström; [2023]
    Keywords : hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

    Abstract : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. READ MORE

  3. 12. Development and evaluation of concepts for a high acceleration test rig : Development of a test rig, which aims to expose components to large and controllable accelerations

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Axel Jansson; [2023]
    Keywords : High acceleration; ballistics; acceleration test rig;

    Abstract : This thesis work is dedicated towards finding a feasible test rig design, which can expose small components, produced by SAAB, to a variety of accelerations under different conditions. A literature study is conducted with the objective of gathering information regarding high acceleration testing, where relevant components, designs and calculation methods are presented. READ MORE

  4. 13. Fast deep discharging using a controllable load as pretreatment for EV battery recycling : A study on efficacy, speed, and safety

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lucas Van Genechten; [2023]
    Keywords : Recycling; lithium-ion battery; deep discharging; external short-circuit; internal pressure; thermal stability; Electrochemical impedance spectroscopy; Återvinning; litiumjonbatteri; djupurladdning; extern kortslutning; internt tryck; termisk stabilitet; electrochemical impedance spectroscopy;

    Abstract : In response to the present and projected growth of the EV industry, the development of a large-scale, reliable and efficient lithium-ion battery recycling sector is vital to ensure circularity of the embedded valuable metals and ensure overall sustainability of the technology. One of the main recycling procedures under development is based on hydrometallurgy. READ MORE

  5. 14. A Novel Two-Level Inverter Design for Efficient Energy Conversion in a Maglev Train Rail

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi
