Obstacle Crossing Differences Between Blind and Blindfolded Subjects After Haptic Exploration
Little is known about the ability of blind people to cross obstacles after they have explored haptically their size and position. Long-term absence of vision may affect spatial cognition in the blind while their extensive ...
A fast gradient approximation for nonlinear blind signal processing
When dealing with nonlinear blind processing algorithms (deconvolution or post-nonlinear source separation) complex mathematical estimations must be done giving as a result very slow algorithms. This is the case, for ...
Genesis and sedimentary record of blind channel and islands of the anabranching river: An evolution model
Blind channel (BC) is a fluvial feature formed by attachment of a lateral sand bar to an island or riverbank. It consists of a 10- to 20-m wide and hundreds to thousands meters long channel, parallel to the island or bank, ...

Relationship of color blindness to alcoholic liver damage
Farnsworth-Munsel 100 Hue, Ishihara and hardy-Rand-Ritler tests were performed in a group of 140 alcoholics, who were also studied with routine ’liver tests’ and hepatic biopsy. The high prevalence of color blindness in ...
Irreversible blindness in juvenile systemic lupus erythematosus
(SAGE PUBLICATIONS LTD, 2011)
Blindness caused by severe vasculitis or uveitis is rare in juvenile systemic lupus erythematosus (JSLE) patients. In a 27-year period, 5367 patients were followed at our Paediatric Rheumatology Division and 263 (4.9%) ...
Exploring smart environments through human computation for enhancing blind navigation
In this paper the orchestration of wearable sensors with human computation is explored to provide map metadata for blind navigation. Technological navigation aids for blind must provide accurate information about the ...
