Coherent Modelling of Backscatter and Propagation of Precipitation [PDF]

, 2002
In order to improve knowledge about scattering processes and their effects on the backscattered signal, accurate modelling of radar backscatter is required. In this paper we present a stochstic, coherent and fully-polarimetric scattering model which simulates the propagation of an electromagnetic wave through a medium containing raindrops of various ...

Mechanism for enhanced precipitation strengthening due to the addition of copper to Al-Zn-Mg alloys with high Zn/Mg ratio

Materials & Design, 2023
The mechanism for enhanced precipitation strengthening due to the addition of copper to Al-9.0Zn-1.5Mg (wt.%) alloys has been investigated by means of tensile test, transmission electron microscopy, anomalous small-angle X-ray scattering and three ...

Optimising predictor domains for spatially coherent precipitation downscaling [PDF]

Hydrology and Earth System Sciences, 2013
Statistical downscaling is widely used to overcome the scale gap between predictors from numerical weather prediction models or global circulation models and predictands like local precipitation, required for example for medium-term operational forecasts

A Coherent Approach to Evaluating Precipitation Forecasts over Complex Terrain

Atmosphere, 2022
Precipitation forecasts provided by high-resolution NWP models have a degree of realism that is very appealing to most users of meteorological data. However, it is a challenge to demonstrate whether or not such forecasts contain more skillful information

Shear band-driven precipitate dispersion for ultrastrong ductile medium-entropy alloys

Nature Communications, 2021
Precipitation hardening, used as an effective strengthening strategy in various alloy systems, has been usually achieved by coherent precipitates.

Synergism between coherent precipitation strengthening and FCC-HCP type transformation-induced plasticity

Materials & Design, 2022
It is becoming a trend that many strengthening methods are applied at the same time to overcome the strength-ductility trade-off. However, the combination of precipitation strengthening and transformation-induced plasticity (TRIP) is rarely used ...

TEM Study of High-Temperature Precipitation of Delta Phase in Inconel 718 Alloy [PDF]

, 2011
Inconel 718 is widely used because of its ability to retain strength at up to 650◦C for long periods of time through coherent metastable γ” Ni3Nb precipitation associated with a smaller volume fraction of γ’ Ni3Al precipitates.
