The KCICLO correction‐calibration method and the AOD diurnal cycle: Application to AOD data series

AIP Conference Proceedings, 2009
The aerosol optical depth (AOD) very often shows a distinct diurnal cycle pattern, which results to be an artifact arising from an incorrect calibration (or an equivalent effect, as filter degradation). The shape of this fictitious AOD diurnal cycle varies as the solar air mass (or the solar zenith angle, SZA) and the magnitude of the effect is largest

Nitrogen Control in AOD Converter

Materials Science Forum, 1999
Most stainless steel grades have certain nitrogen target. Refining in AOD is carried out in Outokumpu Polarit with six different gases or gas mixtures to minimise the production costs. The process control model uses nitrogen as inert gas instead of argon as far as possible. Just low nitrogen grades are refined using only argon-oxygen mixture.

Influence of AOD remotely sensed products, meteorological parameters, and AOD–PM2.5 models on the PM2.5 estimation

Stochastic Environmental Research and Risk Assessment, 2021
Air pollution has emerged as one of the most urgent problems worldwide over the past few years. Especially, fine particulate matter with a diameter smaller than 2.5 micrometres (PM2.5) has seriously endangered the human life and health worldwide.

AOD dans le SAPL

JMV-Journal de Médecine Vasculaire, 2020
Le syndrome des antiphospholipides (SAPL) est une thrombophilie acquise caracterisee par l’association d’antecedents thrombotique, veineux, arteriel ou microcirculatoire, ou la presence d’evenements obstetricaux a la positivite d’anticorps antiphospholipides.

Traumatic Atlantooccipital Dislocation (AOD)

2010
Atlanto-occipital dislocation (AOD) is a rare, highly unstable ligamentous injury of the craniovertebral junction (CVJ) and, as such, is associated with high mortality and neurological morbidity. It is seen in up to 31% of high velocity traffic injuries.

La Pharmacologie des AOD

Les pathologies vasculaires (anciennement ANGEIOLOGIE), 2019
es AOD et les AVK ont des profils pharmacodynamiqueet pharmacocinétique radicalement différents. Les voiesenzymatiques empruntées, le mode d’action, l’éliminationhépatique et rénale sont singulières. Cette nouvelle génération d’anticoagulants oraux ne constitue pas une simpleclasse thérapeutique mais chaque représentant a sespropres caractéristiques.

AOD-Net: All-in-One Dehazing Network

2017 IEEE International Conference on Computer Vision (ICCV), 2017
This paper proposes an image dehazing model built with a convolutional neural network (CNN), called All-in-One Dehazing Network (AOD-Net). It is designed based on a re-formulated atmospheric scattering model. Instead of estimating the transmission matrix and the atmospheric light separately as most previous models did, AOD-Net directly generates the ...

TDOA/AOD/AOA localization in NLOS environments

2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
In this paper we present a novel localization algorithm for use in non-line-of-sight environments. We use the single bounce scattering model to model the non-line-of-sight propagations and estimate the position of a mobile station when the observations are the time-difference-of-arrival, the angle-of-departure, and the angle-of-arrival.

A consistent aerosol optical depth (AOD) dataset over mainland China by integration of several AOD products

Atmospheric Environment, 2015
Abstract The Moderate Resolution Imaging Spectroradiometer (MODIS), the Multiangle Imaging Spectroradiometer (MISR) and the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) provide validated aerosol optical depth (AOD) products over both land and ocean.

Fundamental decarburisation model of AOD process

Ironmaking & Steelmaking, 2013
AbstractA mathematical fluid flow model of gas injection in an argon–oxygen decarburisation (AOD) converter process has been coupled with a high temperature thermodynamic model. The current model is a further enhancement of an earlier developed three-dimensional, three-phase model, to also include some thermodynamics of the process.
