HEAP VERIFICATION OF OBJECT-ORIENTED PROGRAMS IN A POINTS-TO LOGIC


In this paper a verification technique is presented based on the logical
programming language "PROLOG" for object-oriented programs based on the
points-to heap model. The terms "heap", "heap interpretation" and a heap
theory are introduced, and a generalised approach in PROLOG allows to
bridge expressibility gaps as well as other research problems in this
field as discussed in the paper. The chosen model was validated against
[1], which also provides facilities to transform imperative programming
languages with objects into an intermediate representation in PROLOG.

THE METHOD OF DETECTING ERRORS OF THE HUMAN-OPERATORS, BASED
ON THEIR PSYCHOLOGICAL TYPES USING GAME PROGRAMS SIMULATED
THE WORKING PROCESS ON WORKSTATION


This article describes a method of detecting errors of the human-
operators, based on their psychological types using game programs
simulated the working process on workstation. Given technique will help
one to improve methods of professional selection due to the fact that
errors will no longer be random and will be predictable and avoidable.

MODIFICATION OF AREAS HATCHING USING A PARAMETRIC MODEL
OF THE GRID DRAWINGS

The features of the description of the hatch in the files of information
exchange drawings and algorithms of forming areas of hatching in the
modification of design drawings of parts in accordance with the specified
constructions-dimensional torus new values designations. It is shown that
on the basis of the parametric model grid created source electronic file
describing the details of the drawing, with the drawing describing the
conversion hatching areas can be done automatically.

ADAPTIVE CONTROL ALGORITHM FOR A NON-LINEAR OBJECT
WITH A FORCE LIMITED ACTUATING DEVICE


A problem of uncertainties in the control channel and a possible way of
its solution using the adaptive control methods are described. As an
example, a control problem of the flatter is considered, for which it is
essential to suppress vibrations at a high speed. The algorithm is based
on a neural network.

Neural network control system, flatter, uncertainties in control channel,
limitations in the control channel
