an opportunity to run CPU in any algorithm, and many industrial controllers, are part of the automatic control system technological process (ACSTP), allow optimizing the operation of the centrifugal pumping unit and help determine the requirements for the development of digital automatic control system for CPU
Some Qualitative Properties of Multirate Digital Control Systems
- IEEE Trans. Automat. Contr
, 1999
"... We consider multirate digital control systems which consist of an interconnection of a continuous-time nonlinear plant (described by ordinary differential equations), a digital controller (described by ordinary difference equations) which has quantizers (but is otherwise linear), along with the requ ..."

The illusion of Control
- Journal of Personality and Social Psychology
, 1975
"... A series of studies was conducted to elucidate a phenomenon here referred to as the "illusion of control. " An illusion of control was denned as an ex-pectancy of a personal success probability inappropriately higher than the ob-jective probability would warrant. It was predicted that fact ..."

Static Scheduling of Synchronous Data Flow Programs for Digital Signal Processing
- IEEE TRANSACTIONS ON COMPUTERS
, 1987
"... Large grain data flow (LGDF) programming is natural and convenient for describing digital signal processing (DSP) systems, but its runtime overhead is costly in real time or cost-sensitive applications. In some situations, designers are not willing to squander computing resources for the sake of pro ..."

A method for obtaining digital signatures and public-key cryptosystems.
- Communications of the ACM,
, 1978
"... Abstract An encryption method is presented with the novel property that publicly revealing an encryption key does not thereby reveal the corresponding decryption key. This has two important consequences: 1. Couriers or other secure means are not needed to transmit keys, since a message can be encip ..."

LIFETIME OF TRANSIENT CHAOTIC PHENOMENA IN DIGITALLY CONTROLLED SYSTEMS
"... We analyse the digitally controlled motion of a 1 DOF mechanical system, that serves as a model of lathe tool carriages. Our mechanical model consists of a block sliding on a surface near a prescribed velocity, v0, under the action of an electric motor. Because of the mixed viscous and dry friction, ..."
