2. 11. Towards Technology Assessment of Ocean Energy in a Developing Country Context

   Author : Linus Hammar; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electricity; Indian Ocean; technology assessment; ocean energy; Africa; rural electrification; ocean thermal energy conversion; wave power; tidal power;

   Abstract : New technologies for the extraction of valuable ocean resources are emerging: renewable ocean energy. Ocean energy technologies have so far primarily been developed in industrialized countries but will be deployed in both industrialized and developing countries. READ MORE

4. 12. On modelling of postglacial gravity change

   Author : Per-Anders Olsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; accurate predictions of the gravity change are important for e.g. reductions of geodetic observations to a reference epoch. During the last decade; Glacial isostatic adjustment GIA is the Earth s response to glacial-induced load variations on its surface. This phenomenon can today be observed in; contribute different and complemental information on the phenomenon. Knowledge of the gravitational component is important for understanding the underlying geodynamical processes. Further; such as vertical and horizontal deformation of the crust; efforts to observe the surface gravity change in Fennoscandia have been intensified and the observational accuracy successively improved. This offers new possibilities at the same time as it puts new demands on modelling. The purpose of this thesis is to study some aspects of the modelling of GIA-induced gravity change; North America and Fennoscandia. Different observables; relative sea level change and disturbances in the gravity field; for example;

   Abstract : Glacial isostatic adjustment (GIA) is the Earth's response to glacial-induced load variations on its surface. This phenomenon can today be observed in, for example, North America and Fennoscandia. READ MORE

5. 13. Hydrokinetic Resource Assessment : Measurements and Models

   Author : Emilia Lalander; Mats Leijon; Mitsuhiro Kawase; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The conversion of kinetic energy in water currents into electricity has gained great attention the past years. The conversion systems are stand-alone units that typically consist of a turbine, driven by the water stream, with a generator connected to it. READ MORE

6. 14. Modelling the hydrokinetic energy resource for in-stream energy converters

   Author : Emilia Lalander; Ole Gunnar Dahlhaug; Uppsala universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Hydrokinetic energy, referring to the energy contained in moving water, is a renewable energy source that has gained much attention the past years. The energy is found in all moving water masses, but is only economical to convert for water masses moving with high velocity, i.e. likely around 1 m/s and above. READ MORE

7. 15. Solar Variability Assessment in the Built Environment : Model Development and Application to Grid Integration

   Author : David Lingfors; Joakim Widén; Jan Kleissl; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Variability; Photovoltaics; Grid Integration; Distributed Generation; LiDAR; GIS; Engineering Science; Teknisk fysik;

   Abstract : During the 21st century there has been a rapid increase in grid-connected photovoltaic (PV) capacity globally, due to falling system component prices and introduction of various economic incentives. To a large extent, PV systems are installed on buildings, which means they are widely distributed and located close to the power consumer, in contrast to conventional power plants. READ MORE
