   Author : Simon Lindroth [formerly Tyrberg]; Mats Leijon; Brian Holmes; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; Measurement systems; Marine technology; Energy conversion; Renewable energy; Energy absorption; Wave resource; Oceanic engineering; Linear generators; Point absorbers; Sea trials; Camera systems; Accelerometers; Offshore experiments; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Abstract : On March 13th, 2006, the Division of Electricity at Uppsala University deployed its first wave energy converter, L1, in the ocean southwest of Lysekil. L1 consisted of a buoy at the surface, connected through a line to a linear generator on the seabed. READ MORE

4. 2. Energy from Ocean Waves : Full Scale Experimental Verification of a Wave Energy Converter

   Author : Rafael Waters; Mats Leijon; Jan Sundberg; Jonny Hylander; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; wave energy converter; sea trials; ocean energy; linear generator; point absorber; search coil; wave climate; utilization; Engineering physics; Teknisk fysik;

   Abstract : A wave energy converter has been constructed and its function and operational characteristics have been thoroughly investigated and published. The wave energy converter was installed in March of 2006 approximately two kilometers off the Swedish west coast in the proximity of the town Lysekil. READ MORE

5. 3. Terrain navigation for underwater vehicles

   Author : Ingemar Nygren; Magnus Jansson; Stephen Rock; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

   Abstract : In this thesis a terrain positioning method for underwater vehicles called the correlation method is presented. Using the method the vehicle can determine its absolute position with the help of a sonar and a map of the bottom topography. READ MORE

6. 4. Assessment of Experimental, Computational, and Combined EFD/CFD Methods for Ship Performance Prediction

   Author : Kadir Burak Korkmaz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical friction line; form factor; CFD; measurement uncertainty; power prediction; EFD; verification and validation; Combined CFD EFD Methods;

   Abstract : In today’s highly competitive market, alongside increasingly stringent regulatory requirements, the precise prediction of ship performance has assumed paramount importance for both design verification and operational evaluations. This thesis addresses the need for a comprehensive assessment of Experimental Fluid Dynamics (EFD), Computational Fluid Dynamics (CFD), and their combination to enhance the accuracy of performance predictions.

7. 5. On the Hydrodynamics of a Monohull Ship in Following and Stern Quartering Seas

   Author : Olov Lundbäck; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The demand for high-speed ships has been increasing by the years and high speed monohull ships are in common use for a wide variety of applications from fast general purpose workboats, pilot boats and patrol crafts to large naval vessels and fast ferries. It has been noted that a large number of high-speed monohull ships suffer relatively high risk for seakeeping problems in following seas, such as surf riding, broaching-to and reduced manoeuvrability in following and quartering seas.
