The efficiency and accuracy of phase equilibrium calculations are essential in compositional reservoir models. Usually, a significant part the computational effort simulations is spent on calculations. nonlinear nature requires an iterative solution procedure. Although successive substitution method (SSM) robust simple to implement, it suffers from slow convergence, especially near critical point...

This paper introduces the Aster distributed composition-based programming system that is aimed at easing the development of distributed runtime systems, customized to the application needs, in a Corba-based environment. Our approach is based on high-level customization: given the speci cation of application requirements using the Aster composition language, a distributed runtime system, customi...

Let G and H be graphs. The strong product GH of graphs G and H is the graph with vertex set V(G)V(H) and u=(u1, v1) is adjacent with v= (u2, v2) whenever (v1 = v2 and u1 is adjacent with u2) or (u1 = u2 and v1 is adjacent with v2) or (u1 is adjacent with u2 and v1 is adjacent with v2). In this paper, we first collect the earlier results about strong product and then we present applications of ...

In normally fertilized eggs the development of the aster is attributed to a substance carried into the egg by the spermatozoon. The aster first makes its appearance in the form of diminutive radiations surrounding the neck-piece of the spermatozoon within a few minutes after it has entered the egg. The writer 1 has shown that the formation of the radiations is accompanied by a jellying of the c...

In this study, ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) stereo imagery was analysed in combination with Global Positioning System (GPS) data and field observations, using Geographical Information Systems (GIS) techniques to examine the potential of satellite remote sensing to support watershed management. Terrain elevation data were derived for the region of Herakl...

Glaciers and snow in the Caucasus are major sources of runoff for populated places many parts this mountain region. These glaciers have shown a continuous area decrease; however, magnitude mass balance changes at regional scale need to be further investigated. Here, we analyzed surface elevation (or thickness) geodetic 1861 (1186.1 ± 53.3 km2) between 2000 2019 from recently published dataset o...

Abstract The assessment of flash flood hazards in the coastal zone Ras Ghareb City (RGC), Red Sea, Egypt, was accomplished through use GIS tools and spatial multi-criteria approach. presented work aims to assess, integrate, generate potential hazard maps. analytic hierarchy process utilized calculate weights vulnerability controlling factors their parameters such as topographical, geological, h...

This paper describes the use of high-spatial-resolution ASTER data to determine the accuracy of the moderate-resolution MODIS active fire product. Our main objective was to develop a methodology to use ASTER data for quantitative evaluation of the MODIS active fire product and to apply it to fires in southern Africa during the 2001 burning season. We utilize 18 ASTER scenes distributed througho...
