Formation and geophysical character of transitional crust at the passive continental margin around Walvis Ridge, Namibia [PDF]
Solid Earth, 2023 When interpreting geophysical models, we need to establish a link between the models' physical parameters and geological units. To define these connections, it is crucial to consider and compare geophysical models with multiple, independent parameters ...

Subspace Methods in Multi-Parameter Seismic Full Waveform Inversion
Communications in Computational Physics, 2020 Summary: In full waveform inversion (FWI) high-resolution subsurface model parameters are sought. FWI is normally treated as a nonlinear least-squares inverse problem, in which the minimum of the corresponding misfit function is found by updating the model parameters.

Flexible lensless endoscope with a conformationally invariant multi-core fiber [PDF]
, 2019 The lensless endoscope represents the ultimate limit in miniaturization of imaging tools: an image can be transmitted through a (multi-mode or multi-core) fiber by numerical or physical inversion of the fiber's pre-measured transmission matrix.
