Flow separation is relevant to many industrial applications, since it is detrimental to the aerodynamic performance of vehicles, induces vibrations in mechanical structures, but can also contribute to improve mixing in combustion devices. In this thesis, t ...
This dissertation develops geometric variational models for different inverse problems in imaging that are ill-posed, designing at the same time efficient numerical algorithms to compute their solutions. Variational methods solve inverse problems by the fo ...
Several Hall sensor configurations have been integrated in CMOS 0.35 mu m technology and analyzed in terms of offset at room temperature and offset drift. We searched for the best geometry that would minimize the offset and its corresponding drift. The tar ...
Smart Morphable Surfaces enable switchable and tunable aerodynamic drag reduction of bluff bodies. Their topography, resembling the morphology of golf balls, can be custom-generated through a wrinkling instability on a curved surface. Pneumatic actuation o ...
In rivers riparian vegetation can have not only strong interaction with the flow but also with the ecological services of the aquatic system. In wetlands and along riverbanks often tree-like vegetation with quite stiff trunks can be found. The study of the ...
Dynamics is a central aspect of ski jumping, particularly during take-off and stable flight. Currently, measurement systems able to measure ski jumping dynamics (e.g., 3D cameras, force plates) are complex and only available in few research centres worldwi ...
The finite cell method (FCM) belongs to the class of immersed boundary methods, and combines the fictitious domain approach with high-order approximation, adaptive integration and weak imposition of unfitted Dirichlet boundary conditions. Its main idea con ...
We investigate the error made by the pairwise summation (PWS) approximation in three geometries where the exact formula for the Casimir interaction is known: atom-slab, slab-slab, and sphere-slab configurations. For each case, the interactions are calculat ...
A big challenge in the last few years is to perform simulations of cardiovascular systems. Since it would be too computational expensive and complicated to simulate an entire blood circuit, an idea is to use a Domain Decomposition (DD) technique and to spl ...
High-concentration solar-power optics require precise two-axis tracking. The planar micro-optic solar concentrator uses a lenslet array over a planar waveguide with small reflective facets at the focal point of each lenslet to couple incident light into th ...
