  2. 1. Electromechanics of Vertical Axis Wind Turbines

    Author : Morgan Rossander; Sandra Eriksson; Hans Bernhoff; Daniel Karlsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; Diode rectification; Control; Measurement; Simulation; Electromechanical coupling; vindkraft; diodlikriktning; reglering; mätning; simulering; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Wind power is an established mean of clean energy production and the modern horizontal axis wind turbine has become a common sight. The need for maintenance is high and future wind turbines may need to be improved to enable more remote and offshore locations. READ MORE

  4. 2. High frequency electronic packaging and components : characterization, simulation, materials and processing

    Author : Christian Johansson; Mats Robertsson; Li-Rong Zheng; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dielectric loss; high frequency electrical characterization; microwave circuits; multilayer thin film technology; ORMOCER®; permittivity; printed diode; sequential build-up; silicone elastomer; Signal processing; Signalbehandling;

    Abstract : Electronic packaging continues to move towards improved performance and lower cost. Requirements of higher performance, reduced size, weight and cost of both high density interconnects and high frequency devices have led to the search for new materials, material combinations, methods, processes and production equipment.

  5. 3. Spin-diode effect and thermally controlled switching in magnetic spin-valves

    Author : Sebastian Andersson; Vladislav Korenivski; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis demonstrates two new device concepts that are based on the tunneling and giant magnetoresistance effects. The first is a semiconductor-free asymmetric magnetic double tunnel junction that is shown to work as a diode, while at the same time exhibiting a record high magnetoresistance. READ MORE

  6. 4. Multilevel Inverter for Wave Power Conversion

    Author : Remya Krishna; Uppsala universitet; []
    Keywords : ;

    Abstract : This thesis deals with the electrical system analysis of a Wave Energy Converter (WEC) for the objective of grid connection. The Linear Permanent Magnet Generator (LPMG) is modeled and validated with experimental results. The comparison studies establish that this model is useful for the subsequent system modeling and performance analysis. READ MORE

  7. 5. Studies of Nanowire Devices Enabled by Advanced Nanofabrication

    Author : Gustav Nylund; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet:2015:Nylund;

    Abstract : This thesis explores the possibility of using advanced device geometries and heterostructure engineering to manipulate, control, and study the electrical and optical properties of semiconductor nanowires. The first part of the thesis investigates the use of different gate-all-around architectures for creating new types of gate-controlled nanowire devices, primarily intended for fundamental studies of semiconductor physics.
