Absolute Nitrogen Atom Density Measurements By Two-Photon Laser-Induced Fluorescence Spectroscopy In Atmospheric Pressure Dielectric Barrier Discharges Of Pure Nitrogen, Et-Touhami Es-Sebbar, Christian Sarra-Bournet, Nicolas Naudé, Françoise Massines, Nicolas Gherardi
Absolute Nitrogen Atom Density Measurements By Two-Photon Laser-Induced Fluorescence Spectroscopy In Atmospheric Pressure Dielectric Barrier Discharges Of Pure Nitrogen, Et-Touhami Es-Sebbar, Christian Sarra-Bournet, Nicolas Naudé, Françoise Massines, Nicolas Gherardi
Dr. Et-touhami Es-sebbar
In this paper, two-photon absorption laser induced fluorescence spectroscopy is used to follow the nitrogen atom density in flowing dielectric barrier discharges fed with pure nitrogen and operating at atmospheric pressure. Two different dielectric barrier discharge regimes are investigated: the Townsend regime, which is homogeneous although operating at atmospheric pressure, and the more common filamentary regime. In both regimes, densities as high as 3x1014 /cm3 are detected. However, the N atoms kinetic formation depends on the discharge regime. The saturation level is reached more rapidly with a filamentary discharge. For a given discharge regime, the N atom density depends strongly …

Titan's atmosphere mainly made of nitrogen and methane is rich in organic molecules. Hydrocarbons are formed from the photolytic dissociation of CH4 and nitriles are created by dissociation of N2 followed by reactions with hydrocarbons. In order to understand the physicochemical mechanisms responsible for the evolution of Titan's atmosphere, photochemical models are built. The latter need constrains for vertical profiles of organic compounds from the high thermosphere down to the low stratosphere as well as photodissociation rates. Those profiles over the entire atmosphere can be retrieved from Cassini observations, in particular by limb sounding, coupling infrared and ultraviolet spectroscopy. However, …

Characterization Of An N2 Flowing Microwave Post-Discharge By Oes Spectroscopy And Determination Of Absolute Ground-State Nitrogen Atom Densities By Talif, Et. Es-Sebbar, Y. Benilan, A. Jolly, M-C. Gazeau
Characterization Of An N2 Flowing Microwave Post-Discharge By Oes Spectroscopy And Determination Of Absolute Ground-State Nitrogen Atom Densities By Talif, Et. Es-Sebbar, Y. Benilan, A. Jolly, M-C. Gazeau
Dr. Et-touhami Es-sebbar
A flowing microwave post-discharge source sustained at 2.45 GHz in pure nitrogen has been investigated by optical emission spectroscopy (OES) and two-photon absorption laser-induced fluorescence (TALIF) spectroscopy. Variations of the optical emission along the post-discharge (near, pink and late afterglow) have been studied and the gas temperature has been determined. TALIF spectroscopy has been used in the late afterglow to determine the absolute ground-state nitrogen atomic densities using krypton as a reference gas. Measurements show that the microwave flowing post-discharge is an efficient source of N (4S) atoms in late afterglow. In our experimental conditions, the maximum N (4S) density …

Vers Un Développement Orienté Services Des Applications Interactives Dans Le Domaine De La Logistique, Étude De Cas, Djilali Idoughi, Christophe Kolski
Professor Djilali IDOUGHI
Cet article contribue au domaine de l’interaction homme-machine (IHM), en proposant un cadre méthodologique global en vue de la spécification de systèmes interactifs dans le domaine de la logistique, pouvant aller jusqu’à la e-logistique. La logistique est vue au sens large en étudiant les besoins des différents acteurs d’une organisation complexe, vis-à-vis de l’exploitation de nouvelles technologies où l’accent est mis sur les services web et l’architecture orientée services. Le cadre proposé a été appliqué sur une étude de cas complexe représentative, relative à la fonction logistique d’un groupe agro-alimentaire.

Dans ce papier, nous discutons du rôle du persona comme outil de modélisation et d’analyse de l’expérience utilisateur. Ce concept est issu des travaux de recherche de marketing sur le comportement du consommateur. Sa finalité est une meilleure compréhension et une prise en compte de l’expérience de l’utilisateur final. L’Expérience Utilisateur ou client (UX) est un terme générique désignant une collection d’information couvrant le comportement de l’utilisateur, incluant les connaissances, l’expertise, et les attributs décrivant la personnalité de l’usager. Un cas d’exemple en logiciel comme service pour la e-maintenance illustre l’approche persona. Le Software as a Service (SaaS, logiciel comme …
