2. 21. Advancing Modeling and Tracking of Deformable Linear Objects for Real-World Applications

   Author : Yuxuan Yang; Todor Stoyanov; Johannes A Stork; Ville Kyrki; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Deformable Linear Object; Model Learning; Model-based Control; Tracking; Robustness;

   Abstract : Deformable linear objects (DLOs), such as cables, wires, ropes, and sutures, are important components in various applications in robotics. Although automating DLO manipulation tasks through robot deployment can offer benefits in terms of cost reduction and increased efficiency, it presents difficult challenges. READ MORE

4. 22. Numerical modelling of fluid flow and particle transport in rough rock fracture during shear

   Author : Tomofumi Koyama; Lahru Jing; Auli Niemi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; single rock fracture; coupled stress-flow test; shear displacement; fluid flow; particle; Geoengineering; Geoteknik;

   Abstract : The effects of different shearing processes and sample sizes on the fluid flow anisotropy and its impact on particle transport process in rough rock fractures are significant factors that need to be considered in the performance and safety assessments of underground nuclear waste repositories. The subjects, however, have not been adequately investigated previously in either laboratory experiments or numerical modeling. READ MORE

5. 23. Tracking and Planning for Surveillance Applications

   Author : Per Skoglar; Fredrik Gustafsson; David Törnqvist; Umut Orguner; Simon Maskell; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; target tracking; sensor control; planning; surveillance; vision sensor;

   Abstract : Vision and infrared sensors are very common in surveillance and security applications, and there are numerous examples where a critical infrastructure, e.g. a harbor, an airport, or a military camp, is monitored by video surveillance systems. READ MORE

6. 24. Laser Sheet Imaging and Image Analysis for Combustion Research

   Author : Rafeef Abu-Gharbieh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear diffusion filtering; optically dense sprays; curve evolution propagation; image sequence analysis; laser induced fluorescence; geodesic paths; level sets; LIF; optical density; spray characterization; flame propagation; laser; particle image velocimetry; spectroscopy; combustion engines; spray diagnostics; Mie scattering; flame fronts; laser attenuation; tracking; combustion diagnostics; curve matching; combustion; laser sheet imaging; PIV; time resolved imaging; segmentation;

   Abstract : This Thesis presents techniques that aim at exploiting the potential of image analysis and processing in order to solve problems of data reduction, interpolation, quantification, and interpretation within the field of experimental laser imaging of combustion processes. Combustion is the most important source of energy for power generation, heating, and transportation in the world today and its strong dominance is projected to continue in the foreseeable future.

7. 25. Particle motion, coating and drying in Wurster fluidized beds - An experimental and discrete element modeling study

   Author : Liang Li; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airflow; Wurster; coating; CFD; particle; Fluidized bed; drying; PEPT; spray; DEM;

   Abstract : This thesis focuses on developing a mathematical model that is capable of predicting the fluidized bed coating process. First a basic understanding of pellet motion in a Wurster fluidized bed was established by conducting a series of experiments using the positron emission particle tracking (PEPT) technique. READ MORE
