1. Marine Current Resource Assessment : Measurements and Characterization
Sammanfattning : 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
2. Resource characterization and variability studies for marine current power
Sammanfattning : Producing electricity from marine renewable resources is a research area that develops continuously. The field of tidal energy is on the edge to progress from the prototype stage to the commercial stage. LÄS MER
3. A Novel Signal Model and Estimation Method for Acoustic Doppler Current Meters
Sammanfattning : This thesis deals with the process of estimating underwater current from the backscattering signal transmitted from an ultrasonic transducer. The narrowband sinusoidal burst signal is Doppler-shifted due to the current, and this information is converted into current. LÄS MER
4. Modeling rating curves from close-range remote sensing data : Application of laser and acoustic ranging instruments for capturing stream channel topography
Sammanfattning : A rating curve provides a functional relationship between water height (i.e. stage) and discharge at a specified cross-section in a river. Used in combination with a time series of stage, rating curves become one of the central components for generating continuous records of streamflow. LÄS MER
5. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes
Sammanfattning : This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamermics and finally sea ice monitoring. Common site for all the studies are the Baltic Sea. LÄS MER
