In the last 25 years optical flow has become more and more important in the field of Computer Vision. Many algorithms have been published since the first paper in 1981 and a lot of concepts have been introduced facing problems which occur when the pixel displacements between frames are determined. Even though todays algorithms explicitly consider violations of their model assumptions, they stil...

Redistribution of air masses due to atmospheric circulation causes loading deformation of the Earth’s crust which can be as large as 20 mm for the vertical component and 3 mm for horizontal components. Rigorous computation of site displacements caused by pressure loading requires knowledge of the surface pressure field over the entire Earth surface. A procedure for computing 3-D displacements o...

This work concerns some features of scalar QFT defined on the causal boundary I+ of an asymptotically flat at null infinity spacetime and based on the BMS-invariant Weyl algebra W(I+). (a) (i) It is noticed that the natural BMS invariant pure quasifree state λ on W(I+), recently introduced by Dappiaggi, Moretti an Pinamonti, enjoys positivity of the self-adjoint generator of u-translations with...

Researchers demonstrate a technique that can track displacements as small 10 nm with sensitivity is independent of field-of-view.

In the first months of 2020, call for papers 2022 Special Issue Annals American Association Geographers was circulated. It invited that engage with multiple forms and meanings displacements their geographies: patterns shifting, dislocation, or putting out place; substitutions one idea another unconscious transfer intense feelings emotions; activities occurring outside normal context; replacemen...

The estimation of local and structural mechanical properties of bones with micro Finite Element (microFE) models based on Micro Computed Tomography images depends on the quality bone geometry is captured, reconstructed and modelled. The aim of this study was to validate microFE models predictions of local displacements for vertebral bodies and to evaluate the effect of the elastic tissue modulu...
