Brightest cluster galaxies (BCGs) are very massive elliptical found at the centers of clusters. Their study gives clues on formation and evolution clusters in which they embedded. We analysed here a homogeneous way properties sample more than one thousand BCGs redshift range 0.15 < z 0.7, based images from Canada France Hawaii Telescope Legacy Survey. Based catalogue 1371 by Sarron et al. (2018...

The aim of this study was to quantify the effects different processing parameters on texture development and incidence white film tyrosine crystals in dry-cured ham. Hams were dry-salted for 0.65, 0.8 or 1.0 days/kg. After drying 45 days at 5 °C, they dried 10, 15 20 °C until reaching 33% weight loss and, thereafter, 25 36 40% loss. salting time, temperature target significantly affected crysta...

In this paper, we present a modeling and implementation of new control schemes for an isolated photovoltaic (PV) using a fuzzy logic controller (FLC). The PV system is connected to a load through a DC-DC boost converter. The FLC controller provides the appropriate duty cycle (D) to the DC-DC converter for the PV system to generate maximum power. Using FLC controller block in MATLABTM/Simulink e...

Common intervals have been defined as a modelisation of gene clusters in genomes represented either as permutations or as sequences. Whereas optimal algorithms for finding common intervals in permutations exist even for an arbitrary number of permutations, in sequences no optimal algorithm has been proposed yet even for only two sequences. Surprisingly enough, when sequences are reduced to perm...

Finding the salient regions in videos has been a very active topic. In this work we compare the modelisation of visual attention on egocentric video recordings for two different points of view. We are interested in finding the relation between the visual saliency maps of the viewer of visual content and the actors (person executing the actions). This question is of importance because the buildi...

Ever since von Neumann [Burks 1969], the question of modeling continuous physics with a discrete set of cellular automata has been raised, whether they handle discrete or continuous values. Many answers have been brought forth through, for instance, the work of Stephen Wolfram [Wolfram 1983] summarized in a recent book [Wolfram 2002]. This problem has been mostly tackled by rightfully consideri...

We introduce an extension of bag-of-words image representations to encode spatial layout. Using the Fisher kernel framework we derive a representation that encodes the spatial mean and the variance of image regions associated with visual words. We extend this representation by using a Gaussian mixture model to encode spatial layout, and show that this model is related to a soft-assign version o...

We present an approach of the problem of handwriting recognition using hidden Markov random fields and based on a trully bidimensional analysis of the handwriting. The main innovative aspect of this approah is the combination of a windowed analysis of the image, a Markovian modelisation and an implementation of the 2D dynamic programming algorithm that achieves a fast and optimal decoding of Ma...

Structural damages can result in nonlinear dynamical signatures that can significantly enhance their detection. An original nonlinear damage detection approach is proposed that is based on a cascade of Hammerstein models modelisation of the structure. This model is estimated by means of the Exponential Sine Sweep Method from only one measurement. On the basis of this estimated model, the linear...
