MATHEMATICAL MODELING OF FINANCIAL PYRAMID SCHEME. PART 2. DISCRETE MODELS
01.00.00 Physical-mathematical sciences
Description
This article analyzes the changes in the number of cases of various clients of the pyramid and the establishment of the basic rules of the pyramid schemes based on discrete models. The article is also a continuation of previous work [1], which had formulas to simulate the amount collected by the pyramid scheme

MATHEMATICAL MODELING OF FINANCIAL PYRAMID SCHEME. PART 1. DEFINITIONS
01.00.00 Physical-mathematical sciences
Description
The article analyzes the various approaches to the mathematical modeling of financial pyramids. It considered “economically rational subject”, game approach and the approach of Dubovsky. In this article, the mathematical models of the unproblematic approaches examined; we also analyzed their characteristics, including the dependence of the lifetime of the pyramid of accrued interest and the number of clients, the maximum possible profit of the founders of the pyramid, etc. This work analyzes the various options of the campaign, including whether the implicit advertising company, which arises from the spread of the financial company clients and rumors about their income

MATHEMATICAL MODELING OF FINANCIAL PYRAMID SCHEME. PART 2. CONTINUOUS MODELS
01.00.00 Physical-mathematical sciences
Description
This article is devoted to the analysis of different cases of changing the number of customers of the financial pyramid and the establishment of the basic rules of the pyramid schemes on the basis of continuous models, and it is a continuation of works [1, 2], which had formulas to simulate the amount collected by the pyramid scheme and it considers the discrete models

INTERFEROMETRIC METHOD OF LASER RADIATION TRANSMISSION USING FREE SPACE OPTICS
01.00.00 Physical-mathematical sciences
Description
The analysis of the various conditions of the two (four) laser radiation streams coherent addition was realized. It is shown that it is possible to create devices providing continuous subtraction of waves. In such radiation stream a continuous subtraction on the line can be replaced by the continuous addition on the photomultiplier by using a dispersive delay line. The research results can be used for creation of modern open atmospheric connection lines

DYNAMIC OF SANITARY CONDITION OF PINE (PINUS SILVESTRIS L.) PLANTINGS DAMAGED BY GROUND FIRE
Description
In the article we have assessed the sanitary condition of pine (Pinus silvestris L.) in the territory of Suburban forestry of Voronezh region affected by fires in 2010. The results indicate about the inevitable death of pine plantations damaged by strong ground fire
-
Description
The article demonstrates the taxation parameters of the pine plantations that was damaged by fire in 2010 in Suburban forestry of the Voronezh region and was calculated the basic ecological functions they performed before death. The intercommunication was found between increasing level of air pollution in the study areas and growing of heart and pulmonary morbidity of population

Description
In the article, we made an estimation of pine cultures’ (Pinus silvestris L.) sanitary condition in the Savalsky Forestry area of the Voronezh region. The obtained results show their considerable weakness, passing to the drying phase because of pine fungus
