2. 16. Multi-scale analysis of mechanical phenomena in NCF composites

   Author : David Mattsson; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : Mechanical phenomenon in Non Crimp Composites is studied in this thesis using a multiscale approach. This approach is choosen due to the architecture of the composite which is heterogenic both on micro as well as mesoscale. READ MORE

4. 17. Computational homogenisation and solution strategies for phase-field fracture

   Author : Ritukesh Bharali; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; irreversibility; multi-scale; slack variable; micromorphic; quasi-brittle; brittle; phase-field fracture; homogenisation;

   Abstract : The computational modelling of fracture not only provides a deep insight into the underlying mechanisms that trigger a fracture but also offers information on the post-fracture behaviour (e.g., residual strength) of engineering materials and structures. READ MORE

5. 18. Electromagnetic Modeling and Sensitivity-Based Optimization of Medical Devices

   Author : Oskar Talcoth; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; helical conductors; optimal measurements; thin-wire approximation; inverse problems; Convex optimization; pacemakers; design of experiments; MR safety; multi-scale; magnetic resonance imaging; magnetic tracking; optimal sensor placement;

   Abstract : Electromagnetics is a fundamental part of biomedical engineering and modern healthcare due to the electromagnetic nature of several important processes in the human body and the interactions of electromagnetic fields with the human body. As a consequence, electromagnetics is exploited for diagnostic and therapeutic purposes by a multitude of medical devices. READ MORE

6. 19. Topographic Control of Groundwater Flow

   Author : Lars Marklund; Anders Wörman; Shulan Xu; Roy Haggerty; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Modeling; Topography; Spectral analysis; Fourier series; Exact solu-tions; Multi-scale; Grundvatten; Modellering; Topografi; Spektralanalys; Fourier serier; Analytisk lösning; Flerskalig; Hydrology; Hydrologi; Environmental engineering; Miljöteknik;

   Abstract : Gravity is the main driving force for groundwater flow, and both landscape topography and geology distribute the effects of gravity on groundwater flow.  The groundwater table defines the distribution of the potential energy of the water. READ MORE

7. 20. Multi-scale analyses of cycled industrial-scale packed-bed adsorbers

   Author : Adam Jareteg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Separations processes account for 10%–15% of the total energy consumed in process industries worldwide. In such separation processes, it is common to use activated carbon in packed-bed adsorbers, to remove undesired substances from a process stream. READ MORE
