Postural control: Visual and cognitive manipulations
… utilization of sensory information for postural control. Past research establishes the possibility that cognitive tasks requiring visual perception may affect the processing of visual information for postural control. The purpose of this study was to investigate the effects of varying demands of …

Control visual de robots paralelos : análisis, desarrollo y aplicación a la plataforma RoboTenis
… trabajo y la ubicación de los objetos no puede controlarse exactamente. Esta limitación se debe implícitamente a la falta de capacidad sensorial en los sistemas robóticos comerciales. La integración sensorial es fundamental para incrementar la versatilidad y el dominio de aplicación de los …

Control visual de un vehiculo aereo autonomo usando deteccion y seguimiento de caracterısticas en espacios exteriores
… concerns in most applications. We address the visual servoing problem for an Unmanned Aerial Vehicle (UAV) in outdoor environments, specifically an autonomous robotic helicopter. We propose vision-based techniques which allow an UAV to perform maneuvers towards features of interest when GPS has …

Control visual basado en características de un sistema articulado. Estimación del jacobiano de la imagen utilizando múltiples vistas
En la presente tesis se aborda el control visual de un sistema de tres grados de libertad utilizando dos cámaras fijas débilmente calibradas. Se trabaja con un esquema de Control Basado en Imagen, y más específicamente en la estimación en línea del jacobiano de la imagen. Se proponen nuevos …

Tácticas, técnicas y protocolos para las fuerzas y cuerpos de seguridad: Un estudio de la praxis profesional, desde un análisis jurídico, sociológico y opertivo.
… sistemas formales e informales de control social, donde intervienen los propios agentes policiales, los sujetos a quien va dirigida la intervención policial y terceras personas que directa o indirectamente se encuentran en el lugar. Modelo dinámico pues los sujetos intervinientes y …

Effect of Age on Visual Dependence for Spatial Orientation and Postural Control
Effective spatial orientation and postural control requires the integration of proprioceptive, vestibular and visual inputs. Increased visual dependence has been reported in older adults but the underlying mechanisms remain unknown. The aims of this research were to investigate the methodological …

Computations of object motion in the visual cortex of the ferret
… a moving stimulus with eyes fixed. Since the visual cortex is retinotopically organized the cortical representations can be expected to move accordingly. In this study we investigated the population membrane potential (PMP) and spiking activity (SA) of the neurons in the visual cortex of 6 …

A framework for energy-efficient housing satisfying socio-cultural aspects in the Kingdom of Bahrain
… be achieved through the design of houses that control visual access to the house by strangers and neighbours, noise transmission from outside to the house and from the inside to the outside of the house and the olfactory. In order to achieve this aim, this research uses mixed research methods …

High-Speed Vision and Force Feedback for Motion-Controlled Industrial Manipulators
… This thesis considers a number of dynamic visual tracking and control problems, as well as the integration of these techniques with contact force control. Different topics ranging from basic theory to system implementation and applications are treated. A new interface developed for external …

The role of peripheral visual cues in planning and controlling movement :|ban investigation of which cues provided by different parts of the visual field influence the execution of movement and how they work to control upper and lower limb motion.
Visual cues have previously been classified as visual exproprioceptive, when defining the relative position of the body within the environment and are continuously updated while moving (online), and visual exteroceptive when describing static features of the environment which are typically …

Postural control and adaptation to threats to balance stability
Postural control is the ability to maintain equilibrium and orientation in a gravitational environment. It is dependent on feedback and feedforward mechanisms that generate appropriate corrective movement based on body-sway motion detected primarily by visual, vestibular, and proprioceptive sensory …
