Estimation of Pan Evaporation Coefficient using Neuro-Genetic Approach [PDF]

open access: yesAmerican Journal of Environmental Sciences, 2011
Énoncé du problème : Le coefficient d'évaporation PAN (Kp) est utilisé pour convertir l'évaporation PAN (Ep) en évapotranspiration de référence (ETo) en raison de sa simplicité et de sa pertinence pour les endroits où la disponibilité des données météorologiques est limitée.

Quality assessment by region in spot images fused by means dual-tree complex wavelet transform [PDF]

open access: yes, 2011
This work is motivated in providing and evaluating a fusion algorithm of remotely sensed images, i.e. the fusion of a high spatial resolution panchromatic image with a multi-spectral image (also known as pansharpening) using the dual-tree complex wavelet

Effects of Meteorological Factors on the Vertical Distribution of Peroxyacetyl Nitrate in Autumn in Tianjin

open access: yesAerosol and Air Quality Research, 2022
With the decrease of PM2.5 concentration, atmospheric photochemical pollution in North China Plain has attracted more and more attention. Peroxyacetyl nitrate (PAN) is an important product and reliable indicator of atmospheric photochemical reaction.

Analysis and multi-dimensional modeling of lithium-air batteries [PDF]

open access: yes, 2014
This study contributes to: 1) a multi-dimensional model framework of lithium-air (Li-air) battery, 2) incorporation of mechanisms of insoluble precipitates' impacts, and 3) analysis and discussion on oxygen supply channel for Li-air battery.

A spectral preserved model based on spectral contribution and dependence with detail injection for pansharpening

open access: yesScientific Reports, 2023
Pansharpening integrates the high spectral content of multispectral (MS) images and the fine spatial information of the corresponding panchromatic (PAN) images to produce a high spectral-spatial resolution image.

Preferential sorption versus preferential permeability in pervaporation [PDF]

open access: yes, 1985
Transport of liquids by pervaporation takes place by a solution—diffusion mechanism. In order to investigate the “solution part” of this transport model, preferential sorption has been compared with preferential permeability.
