Non-Singular Transformation for Inverting Gravity Anomalies Using Satellite Altimetry Data

IEEE Access, 2021
Traditional measurement methods, like shipborne and aerial gravity measurements, cannot cover the entire sea area. Satellite altimetry provides large-scale and high-precision observational data, which can be inverted to give high-precision and high ...

Reconciling surface deflections from simulations of global mantle convection [PDF]

Geoscientific Model Development
The modern state of the mantle and its evolution on geological timescales are of widespread importance for the Earth sciences. For instance, it is generally agreed that mantle flow is manifest in topographic and drainage network evolution, glacio-eustasy,

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Analysis of vertical deflection periodic variations [PDF]

The 9th International Conference "Environmental Engineering 2014", 2014
Most of the geodetic measurements are related with the direction of gravity or vertical. Angular, height difference measurements are performed in horizontal coordinate system. Geodetic measurement data are reduced to a uniform coordinate system prior to processing, taking into account gravity field nonhomogenity.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
