    • Helioseismic diagnostics of solar dynamics in the near-surface layers 

      Poulier, Paul-Louis (2022-02-08)
      This thesis proposes to develop new helioseismic diagnostics of solar near-surface flows. In a first part, we discuss the interaction of solar seismic waves (sound waves) with small-scale turbulent convection. The treatment ...
    • Inverse Problems in Local Helioseismology 

      Pourabdian, Majid (2020-08-04)
      Helioseismology is the main tool to infer the physical properties in the solar interior. In time-distance helioseismology, measurements of wave travel times are extracted from the cross-correlation of the oscillation signal ...
    • isoSTED microscopy for live cell imaging 

      Siegmund, René (2019-05-08)
      Far-field fluorescence microscopy is a versatile tool for the non-invasive investigation of intracellular structures and thus for live cell imaging. This is a major advantage over other microscopy methods such as electron ...
    • Real-time MRI and Model-based Reconstruction Techniques for Parameter Mapping of Spin-lattice Relaxation 

      Wang, Xiaoqing (2017-09-05)
      Magnetic resonance imaging (MRI) is a non-invasive technique widely used for imaging of humans and animals. It came into existence based on several fundamental inventions made in the 1970s. Since then, MRI has evolved into ...
