MODELS OF NEURONET INFLATION IN RUSSIA
01.00.00 Physical-mathematical sciences
DescriptionThe article’s conclusion is that for adequate and effective inflation modeling in Russia by means of modern neuronet technologies it is necessary to consider tendencies of economic development. For training and forecast, it is necessary to use only those periods of time within the limits of which identical economic tendencies work. The article uses modern tool means, such as neuronet, which is offered to technology, for approximation and forecasting of rates of inflation

ISOTOPIC REDISTRIBUTION IN PRODUCTS OF PLASMA PROCESSES FOR HIGH FREQUENCY DISCHARGES
01.00.00 Physical-mathematical sciences
DescriptionResearches in plasma methods for isotopes separation and analyze of the results were done. Results show high values of separation coefficient for intermediate products during the last years. It is shown by us, that these factors will be considerably reduced in the subsequent plasma processes and a way of freezing of high value of factor of division of isotopes

01.00.00 Physical-mathematical sciences
DescriptionIn this article application of the method of computerized system-cognitive analysis and its programmatic tooling – system "Eidoses" for detection of cause and effect associations from the trial-and-error data is considered. In the capacity of a toolkit for the formal submission of cause and effect associations cognitive functions are tendered. Cognitive functions represent many-valued interval functions of many arguments in which one various value of function in a various degree match to various value of arguments, and the quantitative standard of this correspondence appears to be the knowledge, i.e. the information about cause and effect associations in the trial-and-error data, beneficial to a goal achievement

SYNERGETIC METHOD IN THE COGNITION OF MICRO- AND MACRO PHENOMENA: THE EVOLUTIONARY PICTURE OF NATURE
01.00.00 Physical-mathematical sciences
DescriptionThis article reveals a relevant idea of the evolution-al character of modern science. The validity of the unity of nature idea is shown on the concrete cos-mology and physics data. The work unites the con-ceptions of evolution and self-organization. The universe is seen as a dissipative system with period-ically removable elements (elementary dissipative systems). The cooperative evolution presupposes the presence of the circulation between the macro - and micro components of the evolving system as well as the growing complication of the evolution branches. It is stated that the fundamental role in the development of sciences about nature is played by outward factors, i. e. the common cultural back-ground and the cognition development level. At the same time, of a great methodological interest is the disclosure of the internal stimulating motives of development and the interconnection of the devel-opment stages of natural sciences

THE ANALISIS OF SAINT-VENANT EQUATION SYSYEM ANALYTICAL AND NUMERICAL METHODS
01.00.00 Physical-mathematical sciences
DescriptionDiffusion-convection equation that has been received from Saint-Venant differential equation system describing nonstationary fluid motion in a river canal is investigated. Analytical method is considered for the solution of equation with the fixed factors and finite-difference method is considered for the solution of equation system with the float factors. The results of test calculations executed for a reaches of the river Kuban are presented
