2. 1. Modelling and Experimental Verification of Direct Drive Wave Energy Conversion : Buoy-Generator Dynamics

   Author : Mikael Eriksson; Mats Leijon; Jan Isberg; Arne Wolfbrandt; Kim Nielsen; Uppsala universitet; []
   Keywords : Engineering physics; Wave energy; Potential wave theory; Linear generator; Simulations; Experiments; Point absorber; FEM; Equivalent circuit theory; Teknisk fysik; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis is focused on development of models and modelling of a wave energy converter in operation. Through the thesis linear potential wave theory has been used to describe the wave-buoy interaction. The differences lie in the generator models, in the simplest model the generator is a mechanical damper characterized by a damping factor. READ MORE

4. 2. Diving into the zebrafish locomotor network : A study on dI6 interneurons

   Author : Ana Belen Iglesias Gonzalez; Henrik Boije; Filippo Del Bene; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; danio rerio; locomotion; dmrt3a; wt1a; calretinin; transcriptome; spinal cord; morphology; dI6 neurons; knock-down out; Neuroscience; Neurovetenskap;

   Abstract : The generation and coordination of locomotion comprise of inhibitory and excitatory interneurons that govern motor neuron output to muscles. This neuronal network is known as the central pattern generator (CPG). Spinal inhibitory interneurons that originate from the dI6 population play a crucial role in the coordination of locomotor output. READ MORE

5. 3. Linear wave energy converter : Study of electromagnetic design

   Author : Erik Lejerskog; Mats Leijon; Giuseppe Passoni; Uppsala universitet; []
   Keywords : Wave energy; permanent magnets; linear generator; closed stator slots; offshore experiments;

   Abstract : The thesis presents results from synchronous linear wave energy converters developed at Uppsala University. A study is done on closed stator slots and a study presenting offshore data focusing on the power absorption from a wave energy converter (WEC). READ MORE

6. 4. A Generator Perspective on Vertical Axis Wind Turbines

   Author : Fredrik Bülow; Hans Bernhoff; Jens Sørensen; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VAWT; PM generator; Wind power; Stator core loss;

   Abstract : The wind energy conversion system considered in this thesis is based on a vertical axis wind turbine with a cable wound direct drive PM generator. Diode rectifiers are used to connect several such units to a single DC-bus and a single inverter controls the power flow from the DC-bus to a utility grid. READ MORE

7. 5. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator

   Author : Oskar Danielsson; Mats Leijon; Göran Engdahl; Uppsala universitet; []
   Keywords : Engineering physics; Finite element method; linear synchronous generator; longitudinal end effect; permanent magnet; point absorber; offshore testing; wave power; Teknisk fysik;

   Abstract : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. READ MORE
