1. Non-Convex Methods for Compressed Sensing and Low-Rank Matrix Problems
Abstract : In this thesis we study functionals of the type \( \mathcal{K}_{f,A,\b}(\x)= \mathcal{Q}(f)(\x) + \|A\x - \b \| ^2 \), where \(A\) is a linear map, \(\b\) a measurements vector and \( \mathcal{Q} \) is a functional transform called \emph{quadratic envelope}; this object is a very close relative of the \emph{Lasry-Lions envelope} and its use is meant to regularize the functionals \(f\). Carlsson and Olsson investigated in earlier works the connections between the functionals \( \mathcal{K}_{f,A,\b}\) and their unregularized counterparts \(f(\x) + \|A\x - \b \| ^2 \). READ MORE

4. Space-adaptive simulation of transition and turbulence in shear flows
Abstract : Transitional and turbulent shear flows are ubiquitous, from the boundary layer developing on an aeroplane wing to the flow within the aortic arch. In this thesis, we study wall-bounded and free shear flows through direct numerical simulations. READ MORE

5. Healing of marginal defects around implants
Abstract : The purpose of the present series of investigations was to study the healing of marginal defects around implants. The hard-tissue alterations following immediate implant placement in extrac-tion sites were analyzed in 18 patients (study I). READ MORE
