In the present contribution, the applicability of frequencydomain Maximum Likelihood (ML) identification techniques in the field of operational modal analysis is investigated. Attention is paid to the derivation of the spectral densities and noise information required for the ML estimator. The frequency-domain ML approach is applied to a real case study and confidence intervals are derived on t...

QUANTIFICATION OF NEURAL SUBSTRATES OF VERGENCE SYSTEM VIA

Purpose: To investigate how known developmental factors can be incorporated into neural network models of the accommodation and vergence systems. To demonstrate that models of this type can learn adult-like linkages between accommodation and vergence by simple associative mechanisms. Methods: Existing linear systems models were used as a starting point for the design of a series of multi-layer ...

Prior studies have pointed toward a link between the saccadic and vergence systems, coordinating binocular saccadic movements. Recent studies have shown that vergence deficits in children induce poor binocular coordination during saccades, but none of them have studied ocular motility in children during a daily task such as reading. The present study tests whether vergence deficits in children ...

We examined the velocity dependence of the vergence and version eye movements elicited by motion stimuli that were symmetric or asymmetric at the two eyes. Movements of both eyes were recorded with the scleral search coil technique. Vergence was computed as the difference in the positions of the two eyes (left-right) and version was computed as the average position of the two eyes ((left+right)...

A number of recent studies concern algorithms for distributed control and coordination in systems of autonomous mobile robots The common theoret ical model adopted in these studies assumes that the positional input of the robots is obtained by perfectly accurate visual sensors that robot movements are accurate and that internal calculations performed by the robots on real coordinates are perfec...
