Our work has proceeded from the grossly simplified neural model of McCulloch and Pitts, 1943,1 which ignored the effects of disturbances both in the functioning of individual neurons, and in the organization of the neurons into networks. Our recent efforts have been directed to constructing more sophisticated models, albeit still grossly abstracted from neurology, which are designed to combat s...

We present a McCulloch-Pitts neural net to recognize even linear languages. The language class is studied in order to define the net topology. Finally, the equivalence between the language class and the languages recognized by the net is proved.

A Lasting Legacy for London?, a document produced by the London Assembly,2 has highlighted key points of the legacy of previous Games. The legacy left by the Games in four previous host cities – Barcelona in 1992, Atlanta in 1996, Sydney in 2000 and Athens in 2004 – was assessed for nine key sectors.
