1. 11. Extreme wave conditions and the impact on wave energy converters

   Författare :Eirini Katsidoniotaki; Malin Göteman; Vincent Neary; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extreme waves; wave energy converters; CFD; OpenFOAM; environmental contours; focused waves; breaking waves;

   Sammanfattning : The amount of energy enclosed in ocean waves has been classified as one of the most promising renewable energy sources. Nowadays, different wave energy conversion (WEC) systems are being investigated, but only a few concepts have been operated in a sea environment. LÄS MER

3. 12. Additive manufacturing of Ni-based Superalloys- an analysis of parameter and strategy driven properties in Electron Beam Melting Process

   Författare :Xiaoyu Zhao; Amir Rashid; Carolin Körner; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Electron beam melting; Super-alloys; process optimization; surface defects; subsurface defects; mechanical properties; thermal stresses; thermal deformation; Production Engineering; Industriell produktion;

   Sammanfattning : Metal AM processes produce significantly rough surfaces as compared to wrought or machined components. Currently, the as-EBM surfaces are extremely rough and consequently, the as-built components could not be directly used as commercial products. The state-of-the-art research has focused primarily on deeply machined (DM) samples. LÄS MER

4. 13. TM-rolling of heavy plate and roll wear

   Författare :Mikael Jonsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik; Heavy plate;

   Sammanfattning : The heavy plate rolling process needs accurate predictions of the process parameters. The plate thickness, flatness and rolling stability are of this direct influenced as well as the productivity. Therefore, careful calculation of the process parameters and pass schedules is necessary. LÄS MER

5. 14. A Dynamic View of Melodic Organization and Performance : Perception of Structure and Emotional Expression in Music

   Författare :Erik Lindström; Alf Gabrielsson; Andreas C. Lehmann; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; accents; emotion; expression; musical structure; tonal structure; Psykologi; Psychology; Psykologi;

   Sammanfattning : Psychology of music has shown renewed interest in how music expresses emotion to listeners. However, there is an obvious lack of research on how interactions between musical factors such as harmony, rhythm, melodic contour, loudness, and articulation may affect perceived emotion. LÄS MER

7. 15. Controlled fragmentation and contours in rock blasting : theoretical and technical approaches

   Författare :Agne Rustan; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Sammanfattning : The Swedish mining and construction industries have a large interest in improving blasting technology, in milling concerning rock fragmentation by blasting (especially underground in large diameter hole blasting, > 100 mm) and in construction and mining concerning controlled and safe contours in blasted tunnels. This doctoral thesis deals with these matters and includes a licentiate thesis (published in 1970) and five papers A-E included in the doctoral thesis and published during 1983 to 1992. LÄS MER
