Décomposition de spectres en motifs paramétriques par approximation parcimonieuse

We consider the decomposition of a series of spectra such as those acquired in photoelectron spectroscopy [16]: the data consist of several spectra acquired at different times. The peaks in the spectra are assumed to be Gaussian with positive amplitudes and their characteristics vary slowly between two consecutive spectra. This work aims at estimating the peak parameters and their evolution to ...

Approche bayésienne pour la décomposition conjointe d'une séquence de spectres de photo-électrons

This work deals with the decomposition of a temporal sequence of photoelectron spectra into a sum of peaks whose positions, amplitudes and widths are estimated. Since the peaks exhibit a slow evolution with time, the decomposition is performed on the whole sequence to take this temporal information into account. To this end, we have developed a Bayesian model where a Gaussian Markov random fiel...

che guevara mystery spark and its mechanism among the resistance poets

one of the different symbols of a contemporary poet is the historical characters which enjoys the hiroes of the history and has harmony with thoughts, issues and troubles. the present article studies the most imporatnt and most significant che guevara’s symbols such as: resistance symbol, jihad and resistance, awareness and knowledge, hope and wish.  other poets have applied che guevara’s chara...
