Vernier acuity of illusory contours defined by motion
(Association for Research in Vision and Ophthalmology, 2006-08)
We present here a series of experiments exploring a special class of visual completion that is strictly tied to the perception of apparent motion. The stimuli consist of sparse random-dot arrays, in which dots remain in ...
High order computation of the history term in the equation of motion for a spherical particle in a fluid
(Springer/Plenum Publishers, 2004-12)
The historical evolution of the equation of motion for a spherical particle in a fluid and the search for its general solution are recalled. The presence of an integral term that is nonzero under unsteady motion and viscous ...
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 ...
Solar motion and discharge of Paraná River, South America: Evidence for a link
(American Geophysical Union, 2011-10)
A link between climate and the motion of the Sun around the barycenter of the solar system has been suggested, mostly on the basis of interannual cycles observed in climatological data from the Northern Hemisphere. This ...
Parametric decomposition of optic flow by humans
(Pergamon-Elsevier Science Ltd, 2005-09)
Ego motion and natural motions in the world generate complex optic flows in the retina. These optic flows, if produced by rigid surface patches, can be decomposed into four components, including rotation and expansion. We ...
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 ...
Wavelet entropy and fractional Brownian motion time series
(Elsevier, 2006-06-15)
We study the functional link between the Hurst parameter and the normalized total wavelet entropy when analyzing fractional Brownian motion (fBm) time series—these series are synthetically generated. Both quantifiers are ...
The time course of the lower threshold of motion during rapid events of adaptation
(Pergamon-Elsevier Science Ltd, 2001-04)
To examine how the time course of rapid events of adaptation affect motion vision, the lower threshold of motion (LTM) was measured for suprathreshold sinusoidal gratings in presence of transient and steady glare. In the ...
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 ...
Modeling the dynamics of black holes through balanced equations of motion in the null gauge
(World Scientific, 2019-09)
We develop further the general framework for modeling the dynamics of the motion of black holes, presented in [E. Gallo and O. M. Moreschi, Modeling the dynamics of black holes through balanced equations of motion, Int. ...
