Images from the IMAGE Wide-band Imaging Camera (WIC) and Spectrographic Imager (SI) channels SI-12 and SI-13 were compared to in situ data taken by FAST during several substorms. FAST spacecraft observations have shown that the high latitude auroral ionosphere has several distinct regions. Intense auroras are seen in regions of upward directed quasi static electric fields and of Alfven wave accelerated superthermal electrons. In two of the cases presented, the satellite passed through an active poleward propagating substorm surge on its duskward flank. Both show that the superthermal wave accelerated component to be on the polar cap boundary of the surge, and that it could be distinguished from quasi static field ``inverted V'' precipitation which occurred at the more equatorward parts of the auroral oval. In one of these cases, the surge was accompanied by intense ion outflow. Three cases showed the FAST satellite passing through the substorm aurora at midnight or the dawn side outside of the surge and the wave accelerated electrons were less clearly separated from the inverted V type precipitation. The wave accelerated electrons were seen to be part of very short-lived transient events, i.e., bursts. The region of auroral forms, associated with Alfven waves exhibit relatively soft auroral precipitation with very intense electron fluxes. By comparing the intensity of the WIC and SI-13 channels of IMAGE FUV, it is possible sometimes to distinguish optically between the two types of regions. Global imaging of the two regions would allow the separation of quasi-static plasma convection regions containing inverted V-s from regions of Alfven wave driven electrons signifying substorm related magnetic field dynamics.

Narguant les douces utopies démocratiques projetées sur les dispositifs des NTIC, les nouvelles pratiques liées à l’Internet font la part belle au divertissement, et la politique n’y échappe guère ; en témoigne notamment la fréquentation considérable des formes virtuelles du bêtisier politique (vidéos Youtube, etc.), devançant de loin celle des sites politiques ou citoyens. À cet égard, le cas de la « Daerdenmania » est particulièrement interpellant. Le socialiste belge Michel Daerden, baptisé « le Gainsbourg de la politique », connaît grâce à Internet une popularité internationale surprenante qui ne doit rien assurément à ses qualités proprement politiques, mais plutôt à ses qualités de pitre qui en font le héros d’une foultitude de plaisanteries. Or ce phénomène, bien plus qu’une exception à la belge, ne serait-il pas le révélateur d’un mouvement plus général, lié à une personnalisation du politique à la fois exacerbée et transfigurée par les usages émergents des NTIC ? L’exemple des images « daerdenmaniaques » permet d’explorer quelques modalités du rapport contemporain à la politique et témoignerait, non d’un renouveau de l’engagement citoyen dans les rapports de force politiques, mais au contraire d’un désengagement en termes de rapport de farce à la chose politique. En ce sens, ces formes communes de dérision signifieraient l’endormissement croissant de la possibilité du jugement critique, proprement politique, au profit d’une communauté émotionnelle. [less ▲]

A methodology to locate automatically limits or boundaries between different geological bodies in 2D electrical tomography is proposed, using a crest line extraction process in gradient images, This method is applied on several synthetic models and on field data set acquired on three experimental sites during the European project PALEOSIS where trenches were dug. The results presented in this work are valid for electrical tomographies data collected with a Wenner-alpha array and computed with an 1(1) norm (blocky inversion) as optimization method, For the synthetic cases. three geometric contexts are modelled: a vertical and a dipping fault juxtaposing two different geological formations and a step-like structure. A superficial layer can cover each geological structure. In these three situations, the method locates the synthetic faults and layer boundaries, and determines fault displacement but with several limitations. The estimated fault positions correlate exactly with the synthetic ones if a conductive (or no superficial) layer overlies the studied structure. When a resistive layer with a thickness of 6 in covers the model, faults are positioned with a maximum error of 1 m. Moreover, when a resistive and/or a thick top layer is present, the resolution significantly decreases for the fault displacement estimation (error up to 150%). The tests with the synthetic models for surveys using the Wenner-alpha array indicate that the proposed methodology is best suited to vertical and horizontal contacts. Application of the methodology to real data sets shows that a lateral resistivity contrast of 1:5 1:10 leads to exact faults location. A fault contact with a resistivity contrast of 1:0.75 and overlaid by a resistive layer with a thickness or 1 m gives an error location ranging from 1 to 3 m. Moreover, no result is obtained for a contact with very low contrasts (similar to 1:0.85) overlaid by a resistive soil. The method shows poor results when vertical gradients are greater than horizontal ones. This kind of image processing technique should be systematically used for improving the objectiveness of tomography interpretation when looking for limits between geological objects.
