Up, close and personal: the new Front National visual strategy under Marine Le Pen

Extensive analyses of Marine Le Pen’s media interventions as leader of the French Front National have revealed mostly rhetorical differences from her father’s discourse. In particular, despite Marine Le Pen’s professed openness toward women and their policy concerns, and despite her professed intention to transform the FN into party suitable for government, there has been little progress in these directions. However, the FN’s visual discourse has been all but ignored by the scholarly analysis, despite the fact that campaign visuals encode significant social and political information. This paper finds that the FN candidates’ visual presentation has undergone major transformations from the 2007 to the 2012 legislative elections. Specifically FN candidates in 2012 are more likely to visually portray themselves like mainstream party candidates. Compared to the 2007 elections, women candidates, in particular, were more likely to visually promote their personal qualities in 2012, in some respects more than 2012 men candidates

RESTORATION TECHNIQUE FOR PLEIADES-HR PANCHROMATIC IMAGES

17th of December 2011 from Kourou Space Centre, French Guyana. Like others high resolution optical satellites, it acquires both panchromatic images, with 70cm spatial resolution, and lower resolution multispectral images with 2.8m spatial resolution. Pleiades-HR is an optimized system, which means that the Modulation Transfer Function has a low value at Nyquist frequency, in order to reduce both the telescope diameter and aliasing effects. Shannon sampling condition is thus met at first order, which also makes classical ground processing, such as image matching or resampling, more justified for a mathematical point of view. Raw images are thus blurry which implies a deconvolution stage that restores sharpness but also increases the noise level in the high frequency domain. A denoising step, based upon wavelet packet coefficients thresholding/shrinkage technique, allows controlling the final noise level. Each of these methods includes numerous parameters that have to be assessed during the inflight commissioning period: deconvolution filter that depends on MTF assessment, instrumental noise model, noise level target for denoised images, wavelet packet decomposition level. This paper aims to precisely describe the deconvolution/denoising algorithms and how their main parameters have been set up during the inflight commissioning stage. Special attention will be given to structured noise induced by Pleiades-HR on board wavelet-based compression algorith

Surface characterization of zirconium and thorium phosphate compounds

As part of a study involving sorption experiments with actinide ions sorbed onto phosphate compounds and to understand the sorption mechanisms, we have first synthesized the following three solids: ZrP2O7 (zirconium diphosphate), Zr2O(PO4)(2) (zirconium oxophosphate) and Th-4(PO4)(4)P2O7 (thorium phosphate diphosphate). These compounds have been characterized using X-ray powder diffraction, IR spectroscopy and EPMA. The specific surface areas, measured by the N-2-BET method, are 5.5 +/- 0.1, 0.9 +/- 0.2 and 1.2 +/- 0.2 m(2) g(-1) respectively. The average grain size of the powdered samples is around 10 mu m. The pH(IEP) (pH corresponding to the isoelectric point) determined by electrokinetic measurements is 3.6 for ZrP2O7, 4.0 for Zr2O(PO4)(2) and 6.8 for Th-4(PO4)(4)P2O7. By simulation of the titration curves obtained for the three solids, we have determined, using the FITEQL code (constant capacitance model), the surface acidity constants using a sorption site number close to 7 sites nm(-2) for the zirconium diphosphate, 7.5 sites nm-2 for the zirconium oxophosphate and 4 sites nm(-2) for the thorium phosphate diphosphate
