For nearly a century after the publication of Darwin's Origin (1) no well-defined schools of classifiers were recognizable. There were no competing methodologies. Taxonomists were unanimous in their endeavor to establish classifications that would reflect "degree of relationship." What differences there were among competing classifications concerned the number and kinds of characters that were ...

We have studied the formation of relativistic solitary waves due to nonlinearinteraction of strong electromagnetic wave with the plasma wave. Here, our plasma isrelativistic both in temperature and in streaming speed. A set of equations consisting ofscalar and vector potentials together with a third order equation for the enthalpy inphoton gas plasma is obtained analytic...

Abstract BBoxDB Streams is a distributed stream processing system, which allows the handling of multi-dimensional data. Multi-dimensional streams consist n -dimensional elements, such as position data (e.g., two-dimensional positions cars or three-dimensional aircraft). The software an enhancement BBoxDB, key-bounding-box-value store that big supports continuous range queries and spatial joins;...
