Limitations on Position Coding Imposed by Undersampling and Univariance
Position judgements, which are exquisitely precise in the fovea, are markedly degraded in the periphery. In a recent article [Hess & Field (1993) Vision Research, 33, 2663-2670] argue that the poor representation of positional information in peripheral vision is a consequence of uncalibrated spatial disorder of cortical connections rather than due to undersampling of the retinal image. Specific...
متن کاملLimitations imposed by wearing armour on Medieval soldiers' locomotor performance.
In Medieval Europe, soldiers wore steel plate armour for protection during warfare. Armour design reflected a trade-off between protection and mobility it offered the wearer. By the fifteenth century, a typical suit of field armour weighed between 30 and 50 kg and was distributed over the entire body. How much wearing armour affected Medieval soldiers' locomotor energetics and biomechanics is u...
متن کاملLimitations imposed by single DOF actuators on discrete actuator arrays
The Modular Distributed Manipulator System (MDMS) is an array of actuators that is capable of manipulating objects in the plane [1]. Each actuator in the array consists of two closely spaced, orthogonally mounted motorized roller wheels whose combined action approximates a programmable vector force. This paper first derives the equations of motion for transported objects by explicitly consideri...
متن کاملPosition jitter and undersampling in pattern perception
The present paper addresses whether topographical jitter or undersampling might limit pattern perception in foveal, peripheral and strabismic amblyopic vision. In the first experiment, we measured contrast thresholds for detecting and identifying the orientation (up, down, left, right) of E-like patterns comprised of Gabor samples. We found that detection and identification thresholds were both...
متن کاملLimitations Imposed by Beam-beam Effects and Their Remedies
E ects that limit the luminosities of a general purpose linear collider or GLC capable of ~e ~e , ~ ~e and ~ ~ incident channels are discussed together with potential mitigations. The relative characteristics of such channels and their luminosities are predicted based on di ering assumptions { including those for the current con gurations for the NLC at p s ee = 0.5 and 1.0 TeV. Disadvantages r...
