At present, various types of car navigation systems are progressively entering the market. Simultaneously, mobile outdoor navigation systems for pedestrians and electronic tourist guides are already available on handheld computers. Although, the depiction of the geographical information on these appliances has increasingly improved during the past years, users are still handicapped having to in...

End-to-side neurorrhaphy constitutes an interesting option to regain nerve function after damage in selected cases, in which conventional techniques are not feasible. In the last twenty years, many experimental and clinical studies have been conducted in order to understand the biological mechanisms and to test the effectiveness of this technique, with contrasting results. In this updated revie...

A mixed graph is a graph with some directed edges and some undirected edges. We introduce the notion of mixed matroids as a generalization of mixed graphs. A mixed matroid can be viewed as an oriented matroid in which the signs over a fixed subset of the ground set have been forgotten. We extend to mixed matroids standard definitions from oriented matroids, establish basic properties, and study...

Claims have been made for associated degrees of impairment on both visual and auditory performance in unilateral neglect and extinction. Since this evidence is primarily based on different tests in each modality, it is difficult to properly quantify the degree of association between performance in vision and audition. The current study compares visual and auditory extinction and temporal order ...

A leftward spatial bias has been observed with visuospatial attention tasks, including line bisection and the greyscales task. Upper and lower visual field differences have been observed on various tasks, with a lower visual field advantage occurring for motion, global processing and coordinate spatial judgments. Upper visual field advantages occur for visual search, local processing and catego...

Four experiments examined judgements of the duration of auditory and visual stimuli. Two used a bisection method, and two used verbal estimation. Auditory/visual differences were found when durations of auditory and visual stimuli were explicitly compared and when durations from both modalities were mixed in partition bisection. Differences in verbal estimation were also found both when people ...

With the rapid development of RS and more mature and the precision of number of field surveys on the basis of Quick-Bird remote sensing data through visual interpretation of urban public green vegetation diversity survey the exits of mixed. Pixel mixed is one important factor of influence accuracy of Remote sensing image classification. In this article, combine genetic algorithm with BP propaga...

Clustering sets of histograms has become popular thanks to the success of the generic method of bag-of-X used in text categorization and in visual categorization applications. In this paper, we investigate the use of a parametric family of distortion measures, called the α-divergences, for clustering histograms. Since it usually makes sense to deal with symmetric divergences in information retr...

introduction: amblyopia is reduced vision in an eye that has not received adequate use during early childhood.  the most common cause of unilateral visual loss in children is amblyopia with prevalence rate of 1-4 percent in pre-school children . however, effective treatments may prevent intensive complication. this study was done to assess the treatment effects of amplyopia patients who have re...

Color is a critical part of objects representation as well as critical cue for recognizing objects. However, it is less clear how people represent color in memory. The present study aimed at investigating this issue. We designed a procedure based on short-term sensory memory load procedure mixed with a color-priming paradigm. Participants learned three visual stimuli (either non-words – lexical...
