1. 16. Solutions and their ambiguities for structure and motion problems

   Författare :Magnus Oskarsson; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surveying; navigation; autonomously guided vehicles; motion; Computer vision; structure; Mathematics; Matematik;

   Sammanfattning : This thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. LÄS MER

3. 17. Structuring and use of motion data for computer manikin work task simulations

   Författare :Ali Keyvani; Roland Örtengren; D. Lämkull; Gunnar Bolmsjö; Keith Case; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Human Modelling; Computer Manikins; Motion Capture Data Management; Virtual Production Tools; Human Motion Simulation; Motion Synthesis; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Modelling and simulation of human motions are of great interest for a number of industrial applications such as ergonomics and production planning. Over time, efforts have been made to provide computerized human models with biomechanically accurate underlying skeleton and realistically rendered volumetric representation of muscles, skin, clothes, etc. LÄS MER

4. 18. Tilting trains : Technology, benefits and motion sickness

   Författare :Rickard Persson; Evert Andersson; Karl Kottenhoff; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; motion sickness; ride comfort; running time; track geometry; Vehicle engineering; Farkostteknik;

   Sammanfattning : Carbody tilting is today a mature and inexpensive technology allowing higher speeds in curves and thus reduced travel time. The technology is accepted by most train operators, but a limited set of issues still holding back the full potential of tilting trains. LÄS MER

5. 19. Motion Vision Processing in Fly Lobula Plate Tangential Cells

   Författare :Yu-Jen Lee; Karin Nordström; Holger Kraap; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hoverflies; EMD; higher order motion; octopamine; cSIFE; figure-ground discrimination; motion vision; lobula plate tangential cells;

   Sammanfattning : Flies are highly visually guided animals. In this thesis, I have used hoverflies as a model for studying motion vision. Flies process motion vision in three visual ganglia: the lamina, the medulla, and the lobula complex. In the posterior part of lobula complex, there are around 60 lobula plate tangential cells (LPTCs). LÄS MER

7. 20. Sound for Multisensory Motion Simulators

   Författare :Alexander Väljamäe; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; auditory scene synthesis; spatial audio; presence; virtual reality; cognitive acoustics; illusory self-motion; vection ; multisensory optimization;

   Sammanfattning : Interaction in a virtual reality environment often implies situations of illusory self-motion, like, for example, in flight or driving scenarios. Striving for pictorial realism, currently available motion simulators often exhibit relatively poor sound design. LÄS MER
