1. Broadband and HF Radiation from Cloud Flashes and Narrow Bipolar Pulses
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : Remote measurement of electric field generated by lightning has played a major role in understanding the lightning phenomenon. Even though other measurements such as photographic and channel base current have contributed to this research field, due to practical reasons remote measurements of electric field is considered as the most useful tool in lightning research.

2. Electromagnetic Analysis of Hydroelectric Generators
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : Hydropower maintains its position as the most important source of renewable electric energy in the world. The efficiency of large hydropower plants is unsurpassed, and after more than hundred years of development, the technology is mature and highly reliable. LÄS MER
3. Positive streamer discharges in air and along insulating surfaces: experiment and simulation
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : The power quality of modern society relies on the electrical properties of the dielectric insulators used in the power industry. Much research work has been conducted with an aim to understand and predict the insulating behaviour of such materials under different kinds of atmospheric conditions, but still there are many unsolved problems.

4. Dynamic Processes and Active Power Control of Hydropower Plants
Detta är en avhandling från Uppsala : Institutionen för teknikvetenskaper; ElektricitetsläraSammanfattning : Hydro-electricity plays an important role in the safe, stable and efficient operation of electric power systems. Frequency stability of power systems refers to the ability to maintain steady frequency following a severe system upset resulting in a significant imbalance between generation and load. LÄS MER
5. Marine Current Resource Assessment Measurements and Characterization
Detta är en avhandling från Uppsala : Institutionen för teknikvetenskaperSammanfattning : The increasing interest in converting energy from renewable resources into electricity has led to an increase in research covering the field of marine current energy, mainly concerning tidal currents and in-stream tidal turbines. Tides have the advantage of being predictable decades ahead. LÄS MER
