Experimental and analytical study of the motion of a sphere falling along an inclined plane in still water
(Elsevier Science Sa, 2015-08)
In this work, the transient regime of motion of a sphere, that falls along an inclined smooth plane, submerged in still water, is studied experimentally and analytically. Several experiments were performed, with spheres ...
Transient glare: its effect on the lower threshold of motion
(Optical Society of America, 2000-08)
We measured the lower threshold of motion (LTM) of suprathreshold gratings as a function of spatial frequency and contrast, for both transient glare and no-glare conditions. A two alternatives forced choice paradigm, using ...
Thermostatistics of overdamped motion with anisotropic drag forces
(EDP Sciences, 2020-03)
We investigate the consequences of anisotropic drag forces for the thermostatistics of systems of interacting particles in the overdamped motion regime. Systems of confined particles interacting via short-range forces and ...
Learning motion: Human vs. optimal Bayesian learner
(Pergamon-Elsevier Science Ltd, 2010-02)
We used the optimal perceptual learning paradigm (Eckstein, Abbey, Pham, & Shimozaki, 2004) to investigate the dynamics of human rapid learning processes in motion discrimination tasks and compare it to an optimal Bayesian ...
The sparkling Universe: A scenario for cosmic void motions
(Oxford University Press, 2016-10)
Cosmic voids are prominent features of the Universe, encoding relevant information of the growth and evolution of structure through their dynamics. Here, we perform a statistical study of the global motion of cosmic voids ...
The Lévy fractional Brownian motion family as a new paradigm in the modeling of turbulent wave-front phase
(Society of Photo-Optical Instrumentation Engineers, 2007-09-25)
In Perez et al. [J. Opt. Soc. Am. A 21 (10), 2004] we have given a general formalism to model the turbulent wave-front phase by using fractional Brownian motion processes. Moreover, it extends classical results to non- ...
Mixed-state Markov models in image motion analysis
(Springer Verlag Berlín, 2011)
When analyzing motion observations extracted from image sequences one notes that the histogram of the velocity magnitude at each pixel shows a large probability mass at zero velocity, while the rest of the motion values ...
Forelimb muscle and joint actions in Archosauria: Insights from Crocodylus johnstoni (Pseudosuchia) and Mussaurus patagonicus (Sauropodomorpha)
(PeerJ Inc., 2017-11)
Many of the major locomotor transitions during the evolution of Archosauria, the lineage including crocodiles and birds as well as extinct Dinosauria, were shifts from quadrupedalism to bipedalism (and vice versa). Those ...
Applications of low-cost 3D imaging techniques for the documentation of heritage objects
(Sociedad Española de Óptica, 2018-05)
3D image recording has reached an increasing impact on the field of cultural heritage. Applications include documentation of the state of conservation and dimensions of an object, the archaeological survey of artefacts, ...
