Migratory processes in post-Soviet Russia and its regions get new lines which are shown in change of a migratory trend, formation of the centers of migrants attraction of different levels where Stavropol Krai is also among. Migratory processes in the region are char-acterized by both all-Russian and regional lines. According to the nature of migratory processes in the region the post-Soviet period divides into four periods. The first period is characterized by: sustained growth of balance of migration, a positive migratory growth in all cities and areas, a high share in a migratory growth of Russians, Armenians and outflow of North- Caucasus people. Dur-ing the second period the migratory growth and an area with positive balance of migration includ-ing Russians, Armenians are reduced, the positive balance of migration of Dargins, Chechens is restored. During the third period the zone with negative balance of migration extends thanks to the cities and rural areas too, Russian west and south-west migratory trend can be seen very clear, North-Caucasus ethnoses are actively settled in the cities. The fourth period - an area with posi-tive balance of migration, which includes Stavropol and Kavminvodsky agglomerations and their suburbs. Territories of preferable settling of migrants of different nationalities are allocated in the region, and areas of their settling in a varying degree coincide.

Global and regional development are two sides of the same process. In the era of globalization regional components play an important role in the process of development. Displacement and blurring of borders are global trends at the present time. Trans-border interaction results in the formation of trans-border regions as parts of multilayer system. Ethno-cultural space is one of the most important subsystems of this system. Special attention is paid to the modern stage of development, the main factor which became the state border. This article uses the results of the field research of the author

Article is devoted to the definition of a number of characteristics of the state and dynamics of specially protected natural territories of Caucasian Mineral Waters using the re-mote sensing data for the 1984-2014 years. The initial data were used satellite imagery medium spatial resolution over the summer period, obtained with apparatus Landsat. Determination of veg-etation was based on vegetation index NDVI. As a result, studies have revealed an increase in the area forest phytocenoses protected areas, however, recorded an increase in urban areas and the decline in the index NDVI for forest covered areas.

We studied the effect of heavy metal pollution on biological properties of soils cities of the Rostov region. Pollution heavy metal soil was recorded in Rostov-on-don, Gu-kovo, Taganrog. In most cases there was a direct relationship between pollutant concentration and the degree of deterioration of the studied soil properties.

This article analyzes the content of one of the fundamental geo-graphic categories of "inner periphery". As a key factor tori forming the inner periphery of Russia are con-sidered such as the decline of the village and delayed progress. The main properties of the inner periphery of the act and its relative ubiquity, areality, linear and point of development. Importance is given to the ecological role of large inner periphery.

Some methods of social sustainability was elaborated by Russian and inter-national scientists, but there is still no researches of its dynamics with reference to Russian regions. Several social statistical indicators were determined since they are representative in Russian con-ditions, are regularly observed, have easy access and official status. Russian regions integral index of social sustainability was calculated for the years 2001-2012 using evaluation methods. Analysis of distribution of social sustainability index revealed its huge inhomogeneity. Dynamics analysis shows index increasing throughout period of investigation and allows distinguishing five group of regions using mean value of index, its growth and stability of growth.

It has been established that the major environmental problems of soil edges are slitizatsiya, waterlogging, salinization, reduction of the batteries, the development of water and wind erosion, which are prevalent in the black earth and chestnut areas.

The low-temperature (77 K) photoconductivity spectra of CdS crystals has been investigated in the absorption edge region vs the scanning direction of the excitation light wavelength. It is shown that the observed hysteresis of semiconductor photoconductivity spectral dependence can be due to the optical recharge of r-center - the deep compensated acceptor as-sociated with the shallow donor.

For the problem of routing on the transport network on the basis of the criti-cal path, we have developed algorithms for constructing the shortest time path for the sound and setting the duration of the interval operations.

In this paper we investigate the behavior of the plane drops a magnetic fluid with spontaneous magnetization units in an alternating magnetic field. It was found that in a certain frequency range of the external magnetic field drop comes into rotational motion due to rotation of the magnetization effect synchronization units.

The approach has been developed for analysis and synthesis of signals based on variational principles, formed in the language of the frequency representation , which allows for adequacy in terms of reflecting the physical nature of tasks: determining the exact pro-portion of the energy values of the analyzed signal at predetermined frequency intervals; optimal filtering resulting vectors derived components are determined only by the energy of the signal in the relevant frequency interval; generation of signals with a minimum of leakage of energy outside the selected frequency band.

Using the apparatus of the approximation of functions and their derivatives corresponding singular integrals and the method of regularization convergence of the sequence of approximate solutions, which is implemented so-called generalized inverse operators. Built in the result calculation-analytical model allows to obtain a sustainable solutions to ill-posed problems.

It is shown that the motion of a free particle or wave function generates a monochrome or satisfies the rule, according to which the actual speed of the particle is related to the measured velocities of the continuous spectrum of logical multiplication.

In a paper to inspect the problem of calculation of a modular integral from a class of exponential functions is considered. The basic formula for account of a modular integral is introduced. The example of account of a modular integral is indicated. The consideration of this problem is caused by necessity of processing of signals in unitem number systems. The given direction of researches is considered perspective because there is a possibility to increase produc-tivity of computing systems.

The efficient hardware implementation of RNS particularly on field program-mable gate array (FPGA) is very important due to the use of FPGAs in some modern computing systems to achieve flexibility and low time-to-market. The residue number system (RNS) with its inherent parallelism can also be used to enhance the performance of implementation of comput-ing algorithms on FPGAs. However, complex RNS operations such as residue to binary (reverse) conversion, sign detection, scaling, magnitude comparison and overflow detection have not been efficiently implemented on FPGAs until now. In this work, we try to address an approach to increase the speed of residue to binary conversion implementation on FPGAs using parallel-prefix adders. This can be a first step towards fast implementation of complex RNS operations on FPGAs, since residue to binary conversion can also be used to solve other difficult RNS operations.
