Les plans de symtrie sont souvent identifis par lÕexistence dÕune polarisation pure perpendiculaire ces plans. Cependant, ce type de polarisation peut apparatre sans que le plan soit un plan de symtrie. Les plans qui prsentent une polarisation pure suivant leurs normales sont appels Ç plans de dcouplage È, car le systme de trois quations linaires couples par les cosinus directeurs ...

In this study, we investigate the potential of sea ice segmentation by Cand X-band multi-polarisation synthetic aperture radar (SAR) features during late summer. Five highresolution satellite SAR scenes were recorded in the Fram Strait covering iceberg-fast first-year and old sea ice during a week with air temperatures varying around 0 C. Sea ice thickness, surface roughness and aerial photogra...
Circular type’ interferometric system for quantum key distribution is proposed. The system has naturally self-alignment and compensation of birefringence and also has enough efficiency against polarisation dependence. Moreover it is easily applicable to multi-party. Key creation with 0.1 photon per pulse at a rate of 1.2KHz with a 5.4% QBER over a 200m fiber was realized. Quantum key distributi...
We present ROMA, a parallel code to produce joint optimal temperature and polarisation maps out of multidetector CMB observations. ROMA is a fast, accurate and robust implementation of the iterative generalised least squares approach to map-making. We benchmark ROMA on realistic simulated data from the last, polarisation sensitive, flight of BOOMERanG.
background: the poly-allyl diglycol carbonate (padc) detector is of particular interest for development of a fast neutron dosimeter. fast neutrons interact with the constituents of the cr-39 detector and produce h, c and o recoils, as well as (n, α) reaction. these neutron- induced charged particles contribute towards the response of cr-39 detectors. material and methods: electrochemical etchin...
It is shown, that the new phenomena of the T-violating photon polarization plane and neutron spin rotation appear under diffraction in a noncentrosymmetrical diffraction grating. The equations describing the T-violating photon scattering by a diffraction grating and neutron interaction with noncentrosymmetrical crystal have been obtained. These phenomena may be used for time-violating interacti...
