On contents search of equivalent textsThe article shows an approach to design a set, used for text equivalent search. Similar tasks are
analogous to duplicate searching, evaluation of authority and plagiarism, library search organizing
and Internet search systems. To solve this task there are different approaches, focused to meaningfulness,
philological features of a natural language and stylistics. This approach takes into account a set
of features: word frequency, punctuation, morphemic word structure, letter case and artifacts of texts
(letter-digital compositions). Every text, which used for comparison, previous processed according to
the set of features. As a result is formed mask of a text, used as a basis of data for a comparison algorithm.
The software for text equivalent search and the comparison algorithm are implemented on the
Java programming language. Computational experiments included different variants of the algorithm
of search set designing are attended. The software is tested on a set of texts, which includes both original
texts and modifications of them. As a result of computational experiments, areas of growth are defined
and a pattern of software modules communication is showed.

On computer-aided adjustment of automatics for elimination of asynchronous operation with trapezoidal characteristic
The article shows algorithms to determine a position of directional element and compute lengths
of bases of the trapezoidal characteristic of automatics for elimination of asynchronous operation.
Computing of trapezoidal characteristic is the recurrent process, which is focused on determining of directional
element location, trapeze altitude, lengths of trapeze bases. Determining of initial position of
the directional element is based on modified edition of mass center method, and correcting of the slope
angle of directional element is based on split-half method. These algorithms and methods are implemented
as software. Basic data for the software is set of time values, reactance and resistance values,
which is a computing result of transient processes with asynchronous operations. Computational experiment
shows that correctly determined initial position of the directional element is important point
in the problem. If the slope angle of the directional element is a long way from optimal angle, we get
a time increment of the problem solving. The computerization of routine is allowed the electric-powered
modes specialist to cut problem solving time and to simplify decision making in choosing of the
best characteristic for automatics for elimination of asynchronous operation.
