Abstract In this paper we study two operations of merging components in a chain graph, which appear to be elementary operations yielding an equivalent graph in the respective sense. At first, we recall basic results on the operation of feasible merging components, which is related to classic LWF Markov equivalence of chain graphs. These results are used to get a graphical characterisation of fa...

Previous studies on reaching movements have shown that people can adapt to distortions that are either visuomotor (e.g., prism glasses) or mechanical (e.g., force fields) through repetitive training. Other work has shown that these two types of adaptation may share similar neural resources. One effective test of this sharing hypothesis would be to show that one could teach one using the other. ...

PURPOSE When observers focus their stereoscopic visual system for a long time (e.g., watching a 3D movie) they may experience visual discomfort or asthenopia. We tested two types of models for predicting visual fatigue in a task in which subjects were instructed to discriminate between 3D characters. One model was based on viewing distance (focal distance, vergence distance) and another in visu...

Is it advantageous to be strongly lateralized? The current study investigated this question by examining the relationship between visual field asymmetries for lexical tasks and reading performance in a sample of 200 young adults. Larger visual field asymmetries were associated with better reading performance, but this relationship was obtained primarily in those with strong and consistent hand ...

Mobile robotic systems have evolved to include sensors capable of truthfully describing robot status and operating environment as accurately reliably never before. This possibility is challenged by effective sensor data exploitation, because the cognitive load an operator exposed to, due large amount time-dependency constraints. paper addresses this challenge in remote-vehicle teleoperation pro...
