In this paper we compare computational power of two models of analog and classical computers. As a model of analog computer we use the model proposed by Rubel in 1993 called the Extended Analog Computer (EAC) while as a model of classical computer, the Turing machines. Showing that the Extended Analog Computer can robustly generate result of any Turing… (More)

Three simulation algorithms of Turing machines by means of real recursive functions are proposed. Moore’s shifting mapping GS is used to this end. The relationship between a simulation dimension and classes of η -hierarchy is established.

A simple and rapid procedure for the determination of plutonium isotopes in the environment is presented. The procedure combines alpha spectrometry, solvent extraction and liquid scintillation measurements to ensure that both alphaand beta-emitting isotopes are determined. Of five tested extractants, bis-(2-ethylhexyl) phosphoric acid was found to be the… (More)

Analog computation as the study of computation capabilities of continuoustime dynamical systems described by means of differential equations got a resurgence of interest in the last decade after a new glimpse of Cris Moore in [A] on the work of Shanon ([21]), Marion B. Pour-El ([15]), and Lee A. Rubel ([20]). Papers such as [9], [7] and [8], but others not… (More)
