Development of a head-mounted, eye-tracking system for dogs [PDF]

open access: yes, 2011
Growing interest in canine cognition and visual perception has promoted research into the allocation of visual attention during free-viewing tasks in the dog. The techniques currently available to study this (i.e.

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

open access: yesAdvanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

Vision and Reading Difficulties Part 2: Optometric correlates of reading difficulties [PDF]

open access: yes, 2009
In this second article of the series on vision and reading difficulties, the optometric factors (for example refractive error and orthoptic function) that may be associated with reading problems are discussed in detail.

Manufacturing Continuous Fiber‐Reinforced Printing Filaments: Development of a Post‐Consolidation Unit

open access: yesAdvanced Engineering Materials, EarlyView.
A novel, temperature‐controlled post‐consolidation unit is developed to test its potential to improve the melt impregnation process used to manufacture continuous fiber‐reinforced filaments for additive manufacturing of high‐performance thermoplastics.

Prevalence of convergence insufficiency between 18 and 35 years and its relation to body mass index

open access: yesTNOA Journal of Ophthalmic Science and Research, 2019
Background: Convergence insufficiency (CI) is a common condition characterized by patient's inability to maintain binocular alignment on objects as they approach from distance to near. One study has found association between low body mass index (BMI) and

Patterns of Nonlinearity in the Ratio of Stimulus Accommodative Convergence to Accommodation

open access: yes, 1996
Background: This study disputes the assumption that the stimulus accommodative convergence to accommodation (AC/A) ratio is linear. Subjects and Methods: Accommodative convergence induced by minus lenses of varying power (-1.50 to -6.00DS, at intervals

Stereoscopic camera and viewing systems with undistorted depth presentation and reduced or eliminated erroneous acceleration and deceleration perceptions, or with perceptions produced or enhanced for special effects [PDF]

open access: yes, 1991
Methods for providing stereoscopic image presentation and stereoscopic configurations using stereoscopic viewing systems having converged or parallel cameras may be set up to reduce or eliminate erroneously perceived accelerations and decelerations by ...

Ocular Manifestations of Whiplash Injury [PDF]

open access: yesEuropean Medical Journal, 2016
Introduction: Whiplash or indirect injuries to the neck are a common occurrence because of motor vehicle collisions, in which the frequency of ocular complications is largely unknown.
