A Stepwise Downscaling Method for Generating High-Resolution Land Surface Temperature From AMSR-E Data

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
A stepwise downscaling method is proposed for generating high-resolution land surface temperature (LST) from advanced microwave scanning radiometer for the Earth observing system (AMSR-E) data to benefit the fusion of thermal infrared and microwave data ...

Soil Erosion across Scales: Assessing Its Sources of Variation in Sahelian Landscapes under Semi-Arid Climate

open access: yesLand, 2022
Soil erosion varies in space and time. As the contributing surface area increases, heterogeneity effects are amplified, inducing scale effects. In the present study, soil erosion processes as affected by the observation scale and the soil surface ...

Scale Effects on a Tip Rake Propeller Working in Open Water

open access: yesJournal of Marine Science and Engineering, 2019
The scale effect on the accuracy of a numerical simulation in ship hydrodynamics represents an important issue of the propeller numerical analysis. To grasp a better understanding on the influence of this effect, an introspection on the performances of ...

Exact solutions of bending deflection for single-walled BNNTs based on the classical Euler–Bernoulli beam theory

open access: yesNanotechnology Reviews, 2020
At the nanolevel, a classical continuum approach seems to be inapplicable to evaluate the mechanical behaviors of materials. With the introduction of scale parameter, the scale effect can be reasonably described by the modified continuum theory.

Research on the scale effects of solute transport in a bended karst conduit

open access: yesShuiwen dizhi gongcheng dizhi, 2023
Research on the scale effect of solute transport in karst conduits is very important for the correct interpretation of breakthrough curves (BTCs), but the scale effect of solute transport in a bended conduit has not been examined.

Einstein clusters as models of inhomogeneous spacetimes [PDF]

open access: yes, 2020
We study the effect of small-scale inhomogeneities for Einstein clusters. We construct a spherically symmetric stationary spacetime with small-scale radial inhomogeneities and propose the Gedankenexperiment.

Large Scale Pressure Fluctuations and Sunyaev-Zel'dovich Effect [PDF]

open access: yes, 2000
The Sunyaev-Zel'dovich (SZ) effect associated with pressure fluctuations of the large scale structure gas distribution will be probed with current and upcoming wide-field small angular scale cosmic microwave background experiments.

On the mean field dynamo with Hall effect [PDF]

open access: yes, 2006
We study in the present paper how Hall effect modifies the quenching process of the electromotive force (e.m.f.) in Mean Field Dynamo (MFD) theories. We write down the evolution equations for the e.m.f. and for the large and small scale magnetic helicity,

Scale Effect of Sloping Landscape Characteristics on River Water Quality in the Upper Reaches of the Si River in East-Central China

open access: yesLand, 2023
Landscape composition and configuration determine the source of pollutants. They also determine the interception and pollution-holding potential of the surface landscape.
