Considering a cartesian grid we reinterpret Dijkstra’s famous algorithm as an upwind finite difference scheme. The scheme is able to compute approximations of static Hamilton-Jacobi PDEs which arise in front propagation. The method which manage the update of the grid points has the particularity to highly fit parallel purpose. We develop a multi-level parallel strategy which can target a wide r...
Risk management is an important part of system assurance and it is widely used in safety-related system. Railway signal system is one kind of safety-related system and its most important goal is to guarantee the safety of railway system. The method based on risk management can find and solve the security issues of railway signal system more effectively. This paper introduces the basic conceptio...
FIGURE 1 Two-dimensional representation of a spherical structure presenting a morphological particularity on a portion of its surface . AB, arc corresponding to the cross-section of the cap of the sphere presenting the characteristic ; OA = OB = R; 0, angle defining the cap ; v, vector defining the secant planes. S I and S2 are two-dimensional representation of secant planes which intersect (S2...
Starting from reviewing the transnational venture capital investment phenomena, this article points out the necessity to study the transnational venture capital investment, and establish a theoretical framework about the research of the transnational venture capital investment. The framework is composed by the entry system that both investors and attractors find the values of the venture capita...
As part of the DocumentToText project, which is being piloted by TIME University and Horizon data society, we are working to develop an Optical Character Recognition engine to convert all scanned books that exist in Tunisian University into editable textual documents . In this article we present our approach for the development of an OCR system as well as the presentation of the utility of usin...
A dinoflagellate bloom ("red tide" event) dominated by the toxic Gymnodinium catenatum Graham (Gymnodiniales, Dinophyceae; 99.7%) and the noxious Noctiluca scintillans (Mcartney) Kofoid (Noctilucaceae, Dinophyceae; 0.3%) was observed in Bahia de Mazatlán Bay, México, on 24-26 January 2000. Photographic and microscopic analysis of samples during such an event, allowed us to collect evidence of a...
The map of a city’s streets constitutes a particular case of spatial complex network. However a city is not limited to its topology: it is above all a geometrical object whose particularity is to organize into short and long axes called streets. In this article we present and discuss two algorithms aiming at recovering the notion of street from a graph representation of a city. Then we show tha...
Magnetic resonance imaging has revolutionized the diagnosis of shoulder lesions, in many cases becoming the method of choice. However, anatomical variations, artifacts and the particularity of the method may be a source of pitfalls, especially for less experienced radiologists. In order to avoid false-positive and false-negative results, the authors carried out a compilation of imaging findings...
Two amphibian species from China are designated by the specific nomen shuichengensis, which refers to the Shuicheng County (26°34'N, 104°51'E), south of the city of Liupanshui in the province of Guizhou: Megophrys shuichengensis (Amphibia, Anura) and Pseudohynobius shuichengensis (Amphibia, Urodela). The holotypes (holophoronts) of both species were deposited in Department of Biology of the Liu...
The terms oral lichenoid reactions or oral lichenoid lesions refer to lesions histologically and clinically similar to oral lichen planus, though with the particularity that in these cases the underlying cause is identifiable. In addition, these lesions are described according to the causal factor involved, including alterations resulting from direct contact with dental restoration materials, d...
