چکیده
The explosion of the Montserrat volcano (Caribbean Sea) could trigger a major landslide and lead to the generation of a tsunami in the Caribbean Sea. In the worst case scenario, the volume of material reaching the sea has been estimated at 80 millions of cubic meters. The sliding of this mass and the generation of the associated tsunami have been simulated numerically, assuming that the debris behave like a heavy fluid flowing into the sea. The numerical model solves the 3D Navier-Stokes equations for a mixture composed of rocks and water. The generated water waves is then propagated around the coast of Montserrat by means of a shallow water model. The numerical results show that the water heights above sea level are higher than 5 meters within a radius of 5 km of the source.

The surface velocity of natural debris flows is one of the main physical parameters for developing effective disaster prevention techniques. The authors already presented the result of velocity vector field measurement of debris flow by the spatio temporal derivative space method. In this paper, we propose a multi resolution spatio temporal derivative space method, and apply the method to some ...
متن کاملOn Detecting Spatial Regularity in Noisy Images
Detecting spatial regularity in images arises in computer vision, scene analysis, military applications, and other areas. In this paper we present an O(n 5 2 ) algorithm that reports all maximal equally-spaced collinear subsets. The algorithm is robust in that it can tolerate noise or imprecision that may be inherent in the measuring process, where the error threshold is a user-speci ed paramet...

The number of information sources available through both printed and electronic media are ever increasing. Even libraries with sizable collection development budgets are having difficulties in coping with this increase. Yet with the development of new technologies, the possibilities of innovative interlibrary cooperation projects emerge: libraries combining their efforts through various consort...
