  2. 1. Experimental Results of a Load-Controlled Vertical Axis Marine Current Energy Converter

    Author : Johan Forslund; Mats Leijon; Karin Thomas; Jan Sundberg; Tom Blackmore; Uppsala universitet; []
    Keywords : Marine Current; Vertical Axis; Load Control; ; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : This thesis investigates the load control of a marine current energy converter using a vertical axis turbine mounted on a permanent magnet synchronous generator. The purpose of this thesis is to show the work done in the so far relatively uncharted territory of control systems for hydro kinetic energy conversion. READ MORE

  4. 2. Studies of a Vertical Axis Turbine for Marine Current Energy Conversion : Electrical system and turbine performance

    Author : Johan Forslund; Karin Thomas; Cameron Johnstone; Uppsala universitet; []
    Keywords : Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Ocean energy is a field of growing interest when it comes to renewable energy thanks to its high density of energy per unit area, and to the high predictability. Conversion of hydrokinetic energy, found in marine currents, is the utilization of the energy in free-flowing water for conversion to electric energy. READ MORE

  5. 3. Childhood Obesity and Islet Function

    Author : Johan Staaf; Peter Bergsten; Anders Forslund; Hindrik Mulder; Uppsala universitet; []
    Keywords : type 2 diabetes mellitus; Uppsala Longitudinal Study of Childhood Obesity; palmitate; glucose-stimulated insulin secretion; hyperinsulinemia; hyperglucagonemia; GLP-1; glicentin; magnetic resonance imaging; metabolic syndrome; oral glucose tolerance test; centroid; Pediatrik; Pediatrics;

    Abstract : The prevalence of childhood obesity and Type 2 Diabetes Mellitus (T2DM) has increased during recent decades. T2DM is accompanied with functional changes in the islets of Langerhans, which can be identified early in the pathogenesis. READ MORE

  6. 4. Control strategies for various grid conditions in wave energy system

    Author : Md Imran Ullah; Irina Temiz; Johan Forslund; Cecilia Boström; Deepak Elamalayil Soman; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The imperative goal of reducing carbon emissions and reaching net zero emissions in electricity generation has driven various renewable technologies, including wind energy, solar energy, and wave energy, among others. Even though wave energy is a recent addition to the already existing renewable energy technologies, it offers distinct advantages, such as a high power density and lower inter-annual variability compared to wind energy.
