Shape classification using complex network and Multi-scale Fractal Dimension
(ELSEVIER SCIENCE BV, 2010)
Shape provides one of the most relevant information about an object. This makes shape one of the most important visual attributes used to characterize objects. This paper introduces a novel approach for shape characterization, ...
ENVIRONMENTAL CONTEXT SHAPES THE BACTERIAL COMMUNITY STRUCTURE ASSOCIATED TO PELTIGERA CYANOLICHENS GROWING IN TIERRA DEL FUEGO, CHILE
(RAPID COMMUNICATIONS OF OXFORD, 2014)
Semiautomatic dental recognition using a graph-based segmentation algorithm and teeth shapes features
Dental recognition is very important for forensic human identification, mainly regarding the mass disasters, which have frequently happened due to tsunamis, airplanes crashes, etc. Algorithms for automatic, precise, and ...
Frontal sinus recognition for human identification
(Spie - Int Soc Optical Engineering, 2008-12-01)
Many methods based on biometrics such as fingerprint, face, iris, and retina have been proposed for person identification. However, for deceased individuals, such biometric measurements are not available. In such cases, ...
Global axis shape of magnetic clouds deduced from the distribution of their local axis orientation
(Edp Sciences S A, 2013-05)
Context. Coronal mass ejections (CMEs) are routinely tracked with imagers in the interplanetary space, while magnetic clouds (MCs) properties are measured locally by spacecraft. However, both imager and in situ data do not ...
Mean shape of interplanetary shocks deduced from in situ observations and its relation with interplanetary CMEs
(EDP Sciences, 2014-05)
CONTEXT: Shocks are frequently detected by spacecraft in the interplanetary space. However, the in situ data of a shock do not provide direct information on its overall properties even when a following interplanetary coronal ...
Velocity fields using NURBS with distortion control for structural shape optimization
(SpringerNew YorkEUA, 2007)
Environmental context shapes the bacterial community structure associated to Peltigera cyanolichens growing in Tierra del Fuego, Chile
The structure of the associated bacterial community of bipartite cyanolichens of the genus Peltigera from three different environmental contexts in the Karukinka Natural Park, Tierra del Fuego, Chile, was assessed. The ...
Behavior of catalytic pellets at high reaction rates. The effect of edges
(American Chemical Society, 2006-01)
The diffusion and reaction problem in catalytic pellets of any shape subject to diffusive transport limitations is undertaken in this contribution. Effective reaction rates in three-dimensional (3D) catalysts can be evaluated ...
