Driver distraction and safety concerns have been identified for new highway logo sign configurations. This study assessed driver perception of logo signs and distraction under nine-panel, overflow-combination, or standard six-panel formats. A nine-panel sign has nine business panels within a single sign; a six-panel sign has six panels within a sign; an overflow-combination consists of a standa...

In this paper we present the design and implementation of a dynamic synthesis platform for Greek Sign Language (GSL). The platform utilizes standard virtual character animation and web3d technologies for the synthesis of sign sequences/streams, exploiting digital linguistic resources of both lexicon and grammar of GSL. The input to the platform is written Greek text from early elementary school...

This paper studies two types of threshold-induced effects: a surge of new sign-ups around the time when the thresholds of group-buying deals are reached, and a stronger positive relation between the number of new sign-ups and the cumulative number of sign-ups before the thresholds are reached than afterwards. This empirical study uses a dataset that records the inter-temporal cumulative number ...

The purpose of the study was to assess the relative effectiveness of print, sign, and pictures in the transfer of reading-related information to children who are deaf. By means of personal computers, deaf children were presented CD-ROM-generated stories in four different formats: print only, print plus pictures, print plus sign language, and print plus pictures plus sign. A repeated-measure des...

This study investigated the effects of user factors and cognitive sign features on the guessability of mine safety signs. Sixty naïve participants guessed the meanings and rated the cognitive sign features of 42 Mainland Chinese mine safety signs. The results showed that some user factors were significant predictors of guessing performance, while some were not. As expected, guessability scores ...

Internal medicine residents were surveyed regarding patient sign-outs at shift change. Data were used to design and implement interventions aimed at improving sign-out quality. This quasi-experimental project incorporated the Plan, Do, Study, Act methodology. Residents completed an anonymous electronic survey regarding experiences during signouts. Survey questions assessed structure, process, a...

The Sign Language is a method of communication for deaf-dumb people. Here vision based approach has been used. This paper presents design and implementation of real time Sign Language Recognition system to recognize 26 gestures from the Indian Sign Language using MATLAB .The signs are captured by using web cam. This signs are preprocessed for feature extraction using HSV color model. The obtain...

Traffic sign recognition (TSR), taken as an important component of an intelligent vehicle system, has been an emerging research topic in recent years. In this paper, a traffic sign detection system based on color segmentation, speeded-up robust features (SURF) detection and the k-nearest neighbor classifier is introduced. The proposed system benefits from the SURF detection algorithm, which ach...

Coupling between axial and torsional degrees of freedom often modifies the conformation and expression of natural and synthetic filamentous aggregates. Recent studies on chiral single-walled carbon nanotubes and B-DNA reveal a reversal in the sign of the twist-stretch coupling at large strains. The similarity in the response in these two distinct supramolecular assemblies and at high strains su...

O the last several decades, the use of symbol signs on North American highways has increased significantly. Research has shown that older drivers have difficulty in detecting, reading and understanding symbolic traffic signs. Previous research on their comprehension indicates that some symbols are clearly understood by 90 percent or more of the drivers, while others are understood by fewer than...
