Aug 9, 2021 · As the beam exits the x-ray tube the beam will 'diverge' while the center point (central ray) of the beam will not suffer from any divergence.

Dec 22, 2021 · The discrepancy in the time scales has been demonstrated by the nonuniqueness of hydrodynamic dispersion coefficient versus injection rate (Péclet number).

We present uniqueness and non-uniqueness results for both the linearized and the non-linear problem; as well as a Hölder stability estimate. 1. INTRODUCTION.

Dec 22, 2021 · Here, we used fast, 4D, synchrotron x-ray imaging of single-phase flow experiments to provide two critical contributions that can lead to ...

Flat-field correction methods are implemented in order to eliminate non-uniformities in X-ray imaging sensors. If the compensation is perfect, ...
