1. 21. Image-based numerical modelling of heterogeneous materials

   Författare :Robert Auenhammer; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray computed tomography; image analysis; image-based modelling; Composites;

   Sammanfattning : In science there has always been a desire to visualise the invisible. Since the discovery of X-rays in 1895, imaging research has made remarkable progress. Nowadays, state-of-the-art technology allows to visualise the micro-structure of objects in three dimensions. However, merely visualising the structure is often insufficient. LÄS MER

3. 22. Deep inferior epigastric perforator flap breast reconstruction after mastectomy : An analysis of long-term outcomes and potential complications

   Författare :Andreas Svee; Maria Mani; Fredrik Wärnberg; Alberto Falk Delgado; Morten Kildal; Tine Engberg Damsgaard; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DIEP flap; breast reconstruction; Surgery; Kirurgi; Plastikkirurgi; Plastic Surgery;

   Sammanfattning : This thesis evaluated the long-term effects and satisfaction with outcomes following deep inferior epigastric perforator (DIEP)-based breast reconstruction after mastectomyPaper I is a retrospective cohort study of women who received a unilateral DIEP in 2000–2009 (n = 225) in Uppsala. These women were compared with individually matched women who underwent mastectomy without autologous reconstruction (n = 450). LÄS MER

4. 23. Simple Models for Complex Nonequilibrium Problems in Nanoscale Friction and Network Dynamics

   Författare :David Andersson; Astrid de WIjn; Supriya Krishnamurthy; Nicola Manini; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; tribology; nanofriction; 2d materials; graphene; image reconstruction; social dynamics; common-pool resource; collective action; simple models; teoretisk fysik; Theoretical Physics;

   Sammanfattning : This doctoral thesis investigates three different topics: How friction evolves in atomically thin layered materials (2D materials); How social dynamics can be used to model grand scale common-pool resource games; Benchmarking of various image reconstruction algorithms in atomic force microscopy experiments. While these topics are diverse, they share being complex out-of-equilibrium systems. LÄS MER

5. 24. An Intelligent Multi Sensor System for a Human Activities Space---Aspects of Quality Measurement and Sensor Arrangement

   Författare :Jiandan Chen; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D Reconstruction; Depth Measurement; Depth Reconstruction; Dither; Human Factor; Image Quality; Iso-disparity Surfaces; Multi-Sensor System; Quality Measurement; Sensor Arrangement; Surveillance; Tracking; Uncertainty;

   Sammanfattning : In our society with its aging population, the design and implementation of a highperformance distributed multi-sensor and information system for autonomous physical services become more and more important. In line with this, this thesis proposes an Intelligent Multi-Sensor System, IMSS, that surveys a human activities space to detect and identify a target for a specific service. LÄS MER

7. 25. Geometry and Critical Configurations of Multiple Views

   Författare :Fredrik Kahl; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; algebra; algebraic geometry; field theory; Number Theory; Matematik; Mathematics; reconstruction; image sequence; absolute conic; critical motions; critical surfaces; perspective projection; affine geometry; Euclidean geometry; multiple view geometry; projective geometry; group theory; Talteori; fältteori; algebraisk geometri; gruppteori; Mathematical logic; set theory; combinatories; Matematisk logik; mängdlära; kombinatorik;

   Sammanfattning : This thesis is concerned with one of the core problems in computer vision, namely to reconstruct a real world scene from several images of it. The interplay between the geometry of the scene, the cameras and the images is analyzed. LÄS MER
