1. Spectral Mammography with X-Ray Optics and a Photon-Counting Detector
University dissertation from Stockholm : KTHAbstract : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. READ MORE

2. Autonomous power systems based on renewables On generation reliability and system control
University dissertation from Göteborg : Chalmers University of TechnologyAbstract : Today one billion people are living in non-electrified areas. A majority of the people are living in rural areas in developing countries where there are no possibilities, neither economical nor technical, for grid extension. Instead energy sources like wood and fossil fuels are used. READ MORE

3. Wind-turbine harmonic emissions and propagation through a wind farm
University dissertation from Luleå : Luleå tekniska universitetAbstract : The increasing demand for sustainable energy is one of the driving forces behind the increasing use of wind power by means of wind-turbines in electric power systems. Modern wind turbines commonly employ variable-speed-generator technology associated with a power-electronic converter as part of the grid connection. READ MORE

4. Increasing the hosting capacity of distributed energy resources using storage and communication
University dissertation from Luleå : Luleå tekniska universitetAbstract : The use of electricity from Distributed Energy Resources like wind and solar powerwill impact the performance of the electricity network and this sets a limit to theamount of such renewables that can be connected. Investment in energy storage andcommunication technologies enables more renewables by operating the networkcloser to its limits. READ MORE
