Dynamic Cosine Method for Normalizing Incidence Angle Effect on C-band Radar Backscattering Coefficient for Maize Canopies Based on NDVI

open access: yesRemote Sensing, 2021
Wide mode SAR images have an apparent incidence angle effect. The existing incident angle normalization methods assume that the relationship between the incident angle (θ) and the backscattering coefficient (σPQ) does not change with the growth stage of ...

Soil Moisture Model with Multi Angle and Multi Polarisation Risat-1 Data [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Multi dimensional data (multi frequency, incident angle and polarisation) measurements of σ0 provided better estimates of soil moisture over those derived from single. This particular paper explains a new methodology for soil moisture estimation with the

The strengthening role of micro-sized phases and nano-precipitates in Al–Mg2Si–Cu(–Ni) alloys at 25 °C and 350 °C

open access: yesJournal of Materials Research and Technology, 2023
The strengthening of micro-sized phases and nano-precipitates to the Al–Mg2Si–Cu(–Ni) alloys was studied at 25 °C and 350 °C. In the Al–15%Mg2Si–5%Cu alloy, lots of nano-precipitates (θ″, θ′, σ and Q′ precursor) are formed with the dissolution of Cu-rich

A new class between theta open sets and theta omega open sets

open access: yesHeliyon, 2021
We define θN-closure operator as a new topological operator which lies between the θ-closure and the θω-closure. Some relationships between this new operator and each of θ-closure, θω-closure, and usual closure are obtained.

Study on Dynamic Recrystallization Models of 21-4N Heat Resistant Steel [PDF]

open access: yesArchives of Metallurgy and Materials, 2020
The high-temperature deformation process and dynamic recrystallization (DRX) process of 21-4N were investigated under the conditions of the deformation temperature range of 1273~1453K, the strain rate range of 0.01~10s–1 and the deformation degree of 60%

Involution factorizations of Ewens random permutations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
An involution is a bijection that is its own inverse. Given a permutation $σ$ of $[n],$ let $\mathsf{invol}(σ)$ denote the number of ways $σ$ can be expressed as a composition of two involutions of $[n].$ We prove that the statistic $\mathsf{invol}$ is ...
