Radiolysis of water confined in porous silica: A simulation study of the physicochemical yields
H. Ouerdane, B. Gervais, H. Zhou +2
We investigate the radiolysis of liquid water confined in a porous silica matrix by means of an event-by-event Monte Carlo simulation of electron penetration in this composite syst…
Low-complexity Pruned 8-point DCT Approximations for Image Encoding
V. A. Coutinho, R. J. Cintra, F. M. Bayer +2
Two multiplierless pruned 8-point discrete cosine transform (DCT) approximation are presented. Both transforms present lower arithmetic complexity than state-of-the-art methods. Th…
Energy-efficient 8-point DCT Approximations: Theory and Hardware Architectures
R. J. Cintra, F. M. Bayer, V. A. Coutinho +2
Due to its remarkable energy compaction properties, the discrete cosine transform (DCT) is employed in a multitude of compression standards, such as JPEG and H.265/HEVC. Several lo…
Octal Games on Graphs: The game 0.33 on subdivided stars and bistars
Laurent Beaudou, Pierre Coupechoux, Antoine Dailly +4
Octal games are a well-defined family of two-player games played on heaps of counters, in which the players remove alternately a certain number of counters from a heap, sometimes b…
Sparse Geometric Representation Through Local Shape Probing
Julie Digne, Sébastien Valette, Raphaëlle Chaine
We propose a new shape analysis approach based on the non-local analysis of local shape variations. Our method relies on a novel description of shape variations, called Local Probi…
Anytime Discovery of a Diverse Set of Patterns with Monte Carlo Tree Search
Guillaume Bosc, Jean-François Boulicaut, Chedy Raïssi +1
The discovery of patterns that accurately discriminate one class label from another remains a challenging data mining task. Subgroup discovery (SD) is one of the frameworks that en…
