An extremely compact, all analog and fully parallel implementation of a class of shunting recurrent neural networks that is applicable to a wide variety of FET-based integration technologies is proposed. While the contrast enhancement, data compression, and adaptation to mean input intensity capabilities of the network are well suited for processing of sensory information or feature extraction ...

The invariance principle, introduced by LaSalle [40] and subsequentlygeneralized by Hale [34], gives information on the structure of w-limit sets in dynamical systems possessing a Liapunov function, and the principle and related methods have been used to determine the asymptotic behavior of solutions to a wide variety of evolution equations (see Kefs. [4, 10, 17-19, 23-29, 34, 48, 51, 55, 561)....

Consider the forward link of a mobile communications system with a single transmitter and rather arbitrary randomly time varying channels connecting the base to the mobiles. Data arrives at the base in some random way (and might have a bursty character) and is queued according to the destination until transmitted. The main issues are the allocation of transmitter power and time to the various q...

To make a discovery is to achieve one of the closest approximations to a property right that the scientific career affords. Professional prestige is often closely associated with these acquisitions. Small wonder, then, that acrimonious disputes about priority and independence in discovery have often marred the normally placid tenor of scientific communication. Even less wonder that many histori...
