Physics

Fluorescein and eosin as sensitizing chromophores in near-infrared luminescent ytterbium(III), neodymium(III) and erbium(III) chelates

Near-infrared luminescent ytterbium(III), neodymium(III) and erbium(III) chelates containing organic chromophores derived from fluorescein and eosin have been synthesized and studied spectroscopically. The complexes can be efficiently excited with…

Backscattering behavior and simulation comparison over bare soils using SIR-C/X-SAR and ERASME 1994 data over Orgeval

During April 1994, the three-frequency radar system flew on the Space Shuttle Endeavour, known as SIR-C/X-SAR mission (Shuttle Imaging Radar C/X-Synthetic Aperture Radar). Over the Orgeval watershed (France), the ground condition stayed very wet…

Modèles électriques du transformateur électromagnétique

Le transformateur est un composant fondamental en électrotechnique, son étude constitue l'un des piliers de cette discipline. Nous sommes habitués aujourd'hui à utiliser, pour décrire le fonctionnement des transformateurs, des modèles électriques…

Physics

Single molecule spectroscopy. Perylene in the Shpol'skii matrix n-nonane.

Single perylene molecules in the Shpol'skii matrix n-nonane have been investigated at 1.7 K using a frequency-doubled cw Ti: sapphire laser as an excitation source. Fluorescence excitation spectra within the inhomogeneously broadened 0-0 absorption…

Problème de la motorisation d'un véhicule électrique, 2ème partie

Cet article, en 2 parties, est issu d'une conférence donnée en 1994 (club EEA). Il pose le problème de la motorisation des véhicules électriques à l'échelle du système. Toute la chaîne de traction est prise en compte en intégrant les moteurs…

Propagation of A-waves in a plane plate : An experimental study

The propagation of the A-wave is investigated theoretically on a plane brass plate completly immersed in water or in contact with water on one side and air on the other side. The main characteristics of this wave are calculated: group and phase…

Modelling, Analysis of Parameters and Tests of a Small Electronically Commutated Single-Phase Permanent-Magnet Reluctance Motor

The aim of this study is to evaluate the field flux in a small electronically commutated single-phase permanent magnet reluctance motor. Its structure is inherently three-dimensional. An analytical model is built so that an analysis of parameters…
