They usually solved their problems of different language, looks and religions by conquering limited areas of land and imposing their culture on the existing people. This rough-and-ready solution was confirmed by the Roman, Scandinavian, Saxon and Norman invasions. Thro...

Beneath the Noise, Chaos

The problem of extracting a signal x from a noise-corrupted time n series y x e is considered. The signal x is assumed to be genern n n n ated by a discrete-time, deterministic, chaotic dynamical system F, in nŽ . particular, x F x , where the initial point x is assumed to lie in a n 0 0 Ž . compact hyperbolic F-invariant set. It is shown that 1 if the noise sequence e is Gaussian then it is im...

Essentially she has placed the manor-house setting within contemporary Britain, and migrated its inhabitants to Courcy Castle as a controlled experiment in sociology. In this way, James succ...

Catalog Services play a vital role on Data Grids by allowing users and applications to discover and locate the data needed. On large Data Grids, with hundreds of geographically distributed sites, centralized Catalog Services do not provide the required scalability, performance or fault-tolerance. In this article, we start by presenting and discussing the general requirements on Grid Catalogs of...
