Afonin S. M. Static and dynamic characteristics of a piezoelectric scanning device

Static and dynamic characteristics of a piezoelectric scanning device are investigated; the problems of calculating the characteristics of a compound piezoelectric motor for a scanning device are discussed.

Zyubin V. E. Reflex Language. A mathematical model of control algorithms

The paper describes a mathematical model of the programs in Reflex problem-oriented language which is a dialect of C intended for control algorithms programming as a set of weakly dependent concurrent run-units. The specificity of control systems software is considered. Existing approaches are overviewed and the requirements to the language tools for describing industrial automation objects operation are formulated. A new type of functional polymorphism named event polymorphism is discerned.
