In this paper, we concern the generation of attractive net motion with respect to location external wave source for active spherical carriers. Here recall that exerted acoustic radiation force in an field resulting from incident wave, a scattered and radiated carrier, can be positive, negative, or zero based on object field. Thus, general case, sustainable pulling is not guaranteed. work, by co...

When spatially segregated visual stimuli are presented in alternation, subjects may perceive a single stimulus moving between the two positions (apparent motion). By adjusting spatial and temporal parameters, an ambiguous condition can be created in which perception of back-and-forth motion alternates with the perception of two stationary blinking stimuli. We presented subjects with such ambigu...

Passive haptic displays have several advantages when compared to active devices. Safety elements associated with active haptic displays may make them undesirable for certain applications. One method of actuation for passive haptic robots is through the use of brakes and clutches. Traditionally, friction brakes have undesirable behavior, such as stiction and delay in response time due to mechani...

As urbanization progresses worldwide, earthquakes pose serious threat to livesand properties for urban areas near major active faults on land or subduction zonesoffshore. Earthquake Early Warning (EEW) can be a useful tool for reducing earthquakehazards, if the spatial relation between cities and earthquake sources is favorable for suchwarning and their citizens are properly trained to respond ...

This paper presents new active calibration techniques capable of handling the strong distortions of lenses that exhibit critical features of human-like vision: a wide eld of view for global detection and high resolution at the fovea for precise observation. Those techniques can be achieved online and are based on the combination of controlled camera motion and tracking of environmental features...

Dynamical systems with controlled singularities, such as mechanical systems with active unilateral constraints, are characterized by the admission of the impulsive control actions within their singular motion phases. In a series of our recent works a novel physically based methodology for the singularity description in this class of systems was proposed. The present work introduces a new optima...
