3. 2. Multi-View Reconstruction and Camera Recovery using a Real or Virtual Reference Plane

   Författare :Carsten Rother; KTH; []
   Nyckelord :Computer Vision; 3D Reconstruction; Virtual Model; Virtual Reality; VR; Augmented Reality; Synthetic Models; Image based Rendering;

   Sammanfattning : Reconstructing a 3-dimensional scene from a set of2-dimensional images is a fundamental problem in computervision. A system capable of performing this task can be used inmany applications in robotics, architecture, archaeology,biometrics, human computer interaction and the movie andentertainment industry.

5. 4. On the wood chipping process : a study on basic mechanisms in order to optimize chip properties for pulping

   Författare :Lisbeth Hellström; Torbjörn Carlberg; Per Engstrand; Sören Östlund; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood chipping; Chip formation; Digital Speckle Photography; Friction; Fracture Processes; Analytical model; Laboratory Wood Chipper; Force Measurement; Vibration Synthesis; Energy Efficiency; Chip Damage; TMP; CTMP; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between process parameters and the quality of the chips. LÄS MER

7. 5. Worse than Complex

   Författare :Petter Törnberg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolutionary Developmental Theory; Complexity; Transitions; Naturalism; Innovation; Wicked Systems; Social Movements; Digital Trace Data; Innovation Society; Critical Realism;

   Sammanfattning : This thesis engages with questions on the boundary between what has traditionally been understood as social and natural. The introductory essay contextualizes the specific contributions of the included papers, by noting and exploring a reinvigoration of "naturalism" (the notion of a continuity between the human realm and the rest of natural phenomena) under the banner of Complexity Science.
