This study investigates the hypothesis that variations in symbol sign legibility distance can be accounted for on the basis of a sign's dependence upon high spatial frequency contours to convey critical information. Using digital image processing techniques, highway signs were blurred to remove all high spatial frequency information. A blur recognition threshold was established for each experim...

-This paper proposes a multi-classified and self-directed learning method used for sign language recognition, which adopts statistical template matching methods to recognize sign language. As sign language expressions consist of many frames, SIFT algorithm is used to position key frames and eigenvectors of sign language vocabulary. According to these key frames, the hierarchical discriminate re...

The quantitative estimation of Sea Surface Temperatures from fossils assemblages is a fundamental issue in palaeoclimatic and paleooceanographic investigations. The Modern Analogue Technique, a widely adopted method based on direct comparison of fossil assemblages with modern coretop samples, was revised with the aim of conforming it to compositional data analysis. The new CODAMAT method was de...

Endotheliitis is a major sign of graft rejection. Recipient-derived endothelial cells found in two series of liver and kidney transplants were related to graft rejection. Here, we assessed the presence and the number of chimeric endothelial cells in lung transplants, and their relation with graft rejection. In six males grafted with female lungs out of 193 lung transplantations, endothelial chi...

A numerical algorithm is presented for solving one nonlinear equation in one real variable. Given Fx with brackets A and B, i.e., sign(T^) = -sign^g) * 0, the algorithm finds a zero of F, A < X < B. Alternately, a crossover pair is found, i.e., (X, Y): sign(Fx) = signify) * 0 where there is no floating-point number in the system between X and Y. This feature allows full use of machine precision...

In random allocation rules, typically first an optimal fractional point is calculated via solving a linear program. Lying in the feasible region of the linear program, the fractional point satisfies the underlying constraints. In effect, the point represents a fractional assignment of objects or more generally packages of objects to agents. In order to implement an expected assignment, one must...
