Detection and recognition of traffic signs is an essential task of regulating the traffic, guiding and warning driver’s pedestrians. In traffic sign detection research are categorized into three groups. The first group of researchers believes that traffic sign detection colors are important information by which traffic signs can be detected and classified. The second group believes that detecti...

This paper describes a visual sensor that is able to localize a mobile robot relatively to planar marks. In our application, the planar marks are traffic signs, very common in urban scenarios. As an application for the sensor, we also propose an approach based on Particle Filters for combining the information from the visual sensor and the robot odometry. Experimental results with an actual mob...

  Abstract   Meningeal melanocytoma is a rare tumor of nervous system, which originates from leptomeningeal   melanocytes. The locations of melanocytoma in the nervous system are most frequently in the posterior fossa or along the spinal cord, and usually appear as an extra-axial mass. The manifestations of tumor are most often due to its compressing effect on adjacent nervous structures that c...

Several authors have reported that induced hyperthermia causes new neurological signs to develop in patients with multiple sclerosis. Collins (1938) observed that a patient with multiple sclerosis while receiving fever therapy developed a series of neurological signs that reversed when the fever therapy was terminated. Simons (1937) pointed out that 62% of patients with multiple sclerosis gave ...

PURPOSE This study assessed the oral health knowledge, confidence and practices of Virginia personnel in the Special Supplemental Food Program for Women, Infants and Children (WIC). METHODS In 2009, 257 WIC personnel were electronically emailed via an investigator-designed 22-item Survey Monkey® questionnaire. Descriptive statistics, Chi-square and Fishers Exact tests compared personnel demog...

The practice of ophthalmology and psychiatry meet over in several aspects of patient diagnosis, management & therapy. The ophthalmologists should be able to recognise signs and symptoms of psychiatric disorder. Non organic disorders could have ophthalmologic manifestations related both the afferent system and motor system related symptoms. Ophthalmologist should be aware of conditions like func...

The utilization of symbols such as words and numbers as mental tools endows humans with unrivalled cognitive flexibility. In the number domain, a fundamental first step for the acquisition of numerical symbols is the semantic association of signs with cardinalities. We explored the primitives of such a semantic mapping process by recording single-cell activity in the monkey prefrontal and parie...

Semantic and lexical decision tasks were used to investigate the mechanisms underlying code-blend facilitation: the finding that hearing bimodal bilinguals comprehend signs in American Sign Language (ASL) and spoken English words more quickly when they are presented together simultaneously than when each is presented alone. More robust facilitation effects were observed for semantic decision th...

Building intelligent traffic guide systems has been an interesting subject recently. A good system should be able to observe all important visual information to be able to analyze the context of the scene. To do so, signs in general, and traffic signs in particular, are usually taken into account as they contain rich information to these systems. Therefore, many researchers have put an effort o...

The visual/gestural modality of signed languages allows meaningful form/meaning mappings (iconicity) across numerous basic concepts. Some previous studies show that iconicity affects sign language processing. However work to date does not provide a clear answer about the mechanisms driving such an effect. In three experiments we found differential effects of iconicity in British Sign Language s...
