in ecological monitoring tasks"


approved by 18-th Scientific Advisory Committee (18-19 May 2000)

Full title of the project: "Development of self-organization methods in complex systems for exploring problems of physical structures formation and signal recognition in ecological monitoring tasks" (Â-477 ISTC);

Brief name of the project: "Self-organization processes in ecological applications"

Project manager : Professor, DSc Krot A.M. ( tel. (375 17) 284 20 86);


Participated institutes:

Leading Institute: The United Institute of Informatics Problems of National Academy of Sciences of Belarus


Subcontracted institutes:


Institute of Physics of National Academy of Sciences of Belarus

Belarusian State University

Military Academy of Republic of Belarus (MA RB)


The purpose of the project is the development of self-organization methods in complex systems for exploring problems of physical structures formation and signals recognition in ecological monitoring tasks (Fig.1).


As concrete object of researches in the project two natural systems (media) are investigated: the stratosphere aerosol layer representing a global system, the changes in which happen on distances in hundreds and thousands kilometers during from several weeks till several years, and the aerosol clouds derivated as a result of technogenic emission in low layers of atmosphere (Fig.2).


According to the official invitation letter of ISTC Secretariat Professor, D.Sc. A.M. Krot took part at the work of the European Workshop ISTC-EuroCenter Event "Danish IT Enterprises Visits by CIS Scientists", (Copenhagen, Denmark, 25 February - 1 March 2002). In accordance with the technical program of the Workshop he presented the report "Development of nonlinear dynamics system methods for analysis and recognition of complex signals (including speech, medical and ecological monitoring ones)", having been prepared on the basis of B477 ISTC project proposal. This report has been high estimated by the Organizing Committee of Workshop.


Manager of the project DSc, Professor A.M. Krot is a subject of the biographical record in the world-wide Editions "Who is Who in the World"and "Who is Who in Science and Engineering" from 1995 till now.


During this project fulfilment the following results will be obtained:



a) For the first time, the Boltzmann equation for the operators of density in configuration and momentum (impulse) spaces, which assumes the use of singular potentials of interparticle interaction will be used for learning dynamic behavior of large Poincare systems (LPS) models one- and multi-component gas media;

b) The evolutional equations describing the process of slow flowing gravitational tightening of the spheroidal body based on LPS model, and also the equation of a weak gravitational field will be obtained. On the basis of these equations the capabilities of origin of evolutional structures in the gravitating spheroidal body will be researched. However, besides only scientific sphere of application, measurable results and statistical data processing obtained during experiments with the use of gravimeter, will have priority meaning in the world practice of ecological situation monitoring;

c) The method of definition of self-organization conditions in chaotic dynamical systems will be offered and it will be shown, that by means of methods of Lyapunov stability theory it is possible not only to define the self-organization conditions but also to calculate bifurcation parameter values of researched systems with a high accuracy.

d) New algorithms for proceeding and recognition of lidar signals based on non-linear dynamics methods and neural networks will be developed.

The scientific results obtained within the framework of the given project, will have two important areas of practical application. At first, they will be directed at creation of regional systems of the Earth's atmosphere monitoring, secondly, they will be directed at creation of hard-software for diagnostic and detection of a pathology of different people's diseases.
