Geodesy: Self-rising 2.5D Tiles by Printing along 2D Geodesic Closed Path

International Conference on Human Factors in Computing Systems, 2019
Thermoplastic and Fused Deposition Modeling (FDM) based 4D printing are rapidly expanding to allow for space- and material-saving 2D printed sheets morphing into 3D shapes when heated.

Improved mapping functions for atmospheric refraction correction in SLR [PDF]

, 2002
[1] We present two new mapping functions (MFs) to model the elevation angle dependence of the atmospheric delay for satellite laser ranging (SLR) data analysis.

Magma chambers: what we can, and cannot, learn from volcano geodesy

Philosophical Transactions of the Royal Society A, 2019
Geodetic observations on volcanoes can reveal important aspects of crustal magma chambers. The rate of decay of deformation with distance reflects the centroid depth of the chamber.

Normal gravity field in relativistic geodesy

, 2018
Modern geodesy is subject to a dramatic change from the Newtonian paradigm to Einstein's theory of general relativity. This is motivated by the ongoing advance in development of quantum sensors for applications in geodesy including quantum gravimeters ...

Numerical simulations of the nonlinear Molodensky problem [PDF]

, 2013
We present a boundary element method to compute numerical approximations to the non-linear Molodensky problem, which reconstructs the surface of the earth from the gravitational potential and the gravity vector.

Fusion of GNSS and Satellite Radar Interferometry: Determination of 3D Fine-Scale Map of Present-Day Surface Displacements in Italy as Expressions of Geodynamic Processes

Remote Sensing, 2019
We present a detailed map of ground movement in Italy derived from the combination of the Global Navigation Satellite System (GNSS) and Satellite Synthetic Aperture Radar (SAR) interferometry.

Recent Progress in Geodesy [PDF]

Science, 1900
Let us consider the present status and scope of geodesy and look at its problems with a view to making the best progress possible in the near future. The recent past to be brought under review should not be limited to a single year, but to a few years.

Operando Characterization of Uranium Dendrite Growth in High‐Temperature Molten Salt Electrochemistry by Synchrotron X‐Ray Tomography and Diffraction

Advanced Science, EarlyView.
An operando methodology combining synchrotron X‐ray micro‐computed tomography (SR‐µCT) and high‐energy X‐ray diffraction (HEXRD) investigates uranium dendrite electrodeposition in LiCl‐KCl‐UCl3 molten salt. This enabled in‐situ visualization of dendrite growth and ion diffusion dynamics.
