Some Aspects of Informations
Some aspects of synthesis of new information are investigated. The
mathematical model of bilateral information interactions is suggested.
There are given examples of the practical use of the information
interactions phenomena in nature.

The Ways of Improving Associative Properties
of Neural Network Mathematical Models in the System
of Taxation Management and Control
The purpose of the research is the problem of providing associative
properties of neural models for complex economic objects. The ideas
suggested in the paper are connected essentially with the system of taxation
management and control. The research is devoted to the problem of
creating standard adaptive models of tax-paying enterprises. The main
problem of the prediction model of stochastic object has been solved. Some
suggestions on improving associative properties of neural network are
formulated. A new principle of creating neural network model with good
associative properties ≈ principle of generalized cross-confirmation is
proposed. The principle is illustrated by a specific numeric example.

Multimodal Semantic Representation Based on
Neuronetworks
The article gives an idea of multimodal model of human knowledge
organization. It is shown that the model kernel consists of overmodal
formations the organization principles of which can be explained by means
of text information processing. There is a description of a statistical
algorithm, which allows the automatic building of such formations from a
large amount of text documents by using the hierarchical structure of
dynamic neural networks. It is proved that over-modal formations built
only on the basis of visual text modality are correct but not include another
modal conceptions giving them sense on the physical level.

electronic means, the types of electromagnetic noise originating in them. It
is reduced the review of the known systems electromagnetic compatibility
analysis of electronic means, the models of interjoins and methods of
electromagnetic processes analysis being used in the given systems.

Logic Function Decomposition Algorithm
Aimed at High-Performance Digital Units Synthesis
We present a BDD-based algorithm for logic function decomposition
that is aimed at speed-up of digital units. For synthesis of carry circuits of
arithmetic units we propose iterative use of the algorithm creating
pyramidal structures out of initial linear representation. This improves
circuit performance drastically, leading to novel improved arithmetic unit
implementation.

Multicoloreul Pixel of the Printer
In the article the problems of the information technology of
multicolorful printing are considered. In particular, the new model of a
multicolorful pixel of the color printer is developed. The offered algorithms
are intended for appropriate stages of multicolorful color separation and
allow receiving materials for the comparison of the different color printers
maintaining a dot output.
