The study of the organic matter (OM) of rocks of the deposits of the Tersko-Caspian foredeep (TCF) on the basis of luminescent and chemical-bituminous analyzes was carried out. The increased content and geochemical characteristics of the dispersed organic matter (DOM) of the Middle Jurassic terrigenous complex within the studied territory make it possible to classify these deposits as oil and gas source rocks. According to the elemental composition of the chloroform components of OM using the Van Crevelen diagram, two genetic types of OM are identified: sapropelic and humus-sapropelic. The features of the lithological composition of the Upper Jurassic rocks, the low content of DOM associated with sedimentation conditions, do not allow considering these deposits as a petroleum complex in the context of Jurassic deposits. The conducted of the Jurassic complex rocks allow to assume the possibility of discovery of new accumulations of oil and gas in the presence of resources - reservoirs and traps for HC deposits. In order to search for reservoir scientists and local uplifts, it is necessary to carry out analytical studies, seismogeo-logical modeling and the formation of a detailed volumetric model of the geological environment based on deep seismic 2D cuts and well log data.

Fifty years have passed since the beginning of anti-hail protection (1967) provided in the Central Caucasus areas with the application of crystallizing reagent particles (CRP) of argentum iodide (Agl). The research shows that with the increase in: average annual number of sown hailrisky and hail clouds (Ncls) there is an increase in average annual number of anti-hail rockets (Nahr) supplied with CRP of Agl and leading to environmental pollution; the values of Nahr there is an increase in average annual number of cancer diseases (Ncd) on the protected territories of Andropovskyi and Kochubeevskyi districts. For the objective evaluation of the Nahr effect on the number of skin cancer (Nsc) and respiratory organs (Nro) regression equations were constructed, pair correlation and determination coefficients connecting the values of Nahr with Nsc and Nahr with Nro were calculated. As these coefficient values proved to be more than the critical value given in the Student’s allocation table they are reliable and can serve as a proof of the relation between Nahr and Nsc values and between Nahr and Nsc values of Andropovskyi and Kochubeevskyi districts. The objective method of hail breaking on the protected areas based on estimating optimal application and firing rates in these clouds has been worked out. From 2003 to 2007 the method was being experimentally checked on the stuffs of the protected area of Stavropol militarized service on active hail influencing and other geophysical processes. It was successfully implemented into operational activities of this service. The average physical efficiency of anti-hail protection was estimated at 95,7%. This method can be recommended to different countries when planning and carrying out scientific, experimental and production activities on influencing hailing.

The effect of the concentration and parameters of the sample on the intensity of phosphorescence of glassy solutions of organic compounds with high concentration has been studied. The results obtained under uniform distribution of the intensity of the exciting light in the sample have been compared with them taking into account decrease of the intensity by absorption of light during its propagation along the sample. It is shown that dependence of the intensity of phosphorescence on concentration becomes nonlinear and tends to saturation as consequence of attenuation of the exciting light under it absorption. This effect was demonstrated in a glassy solution of benzophenone in toluene in the range of concentrations from 0.05 to 0.5 mol/l and thickness of the sample 4 mm.

Recovering signals is usually called compensation of distortions that occur when they are registered. The main problem studied in the literature is the instability of the calculated estimates of the input effects to the effects of errors in the registration of responses. Therefore, various methods of regularizing the initial equations are developed on the basis of their transformation into another equation, the solution of which is calculated stably. The most famous technique is the Tikhonov A.N. method of regularization. At the same time, in this paper it is shown that some of the information on the input action may be missing in the response, that is, even if there are no measurement errors, the resulting solution will be approximate. A method for estimating non-recoverable distortions caused by the operator of the recording system is proposed, which can be used at the stage of its synthesis. A linear form of the representation of the impact component accessible for restoration through the impulse response is obtained, so that the restoration problem is reduced to the calculation of its coefficients. A method for regularizing the systems of linear algebraic equations arising on this basis is proposed on the basis of adaptive estimation of the error levels of registration directly from the registered response.

The paper presents the results of an experimental study of the magnetic properties of a magnetic fluid, the storage of a well-developed system of aggregates that have a real magnetic moment. An analysis of the magnetic state of the investigated medium was carried out by studying the processes of magnetization of a magnetic fluid in a magnetostatic and variable magnetic fields. It was determined that when the initial sample was diluted with a dispersion medium, the magnetic moments of the dispersed particles were ordered in a limited volume. This process resulted in the formation of large elastic aggregates, which possess their own magnetic moment. It was established that the processes of magnetization relaxation in such a medium are analogous to the relaxation of magnetically ordered systems with short-range order - elastic dipole glasses. When the sample temperature is lowered below the curing temperature, the system is transformed into a dipole glass, similar to the Ising one.

The Hirota method for construction of soliton solutions is applied to the complexification of the Korteweg-de Vries equation. To use the method, the complex equation is replaced by a system of two third-order equations into two real functions, which, using the Hirota differential operator, is reduced to a bilinear form that is quadratic in the functions considered. The existence of a one-soliton solution is proved, the real part of which has the form of a soliton, and the imaginary part is a kink. It is proved that the use of the classical perturbation theory approach does not make it possible to construct a two-soliton solution. A special connection between unknown functions is found, which made it possible to reduce the system to a single bilinear equation for which a two-soliton solution is constructed. It is shown that the obtained Hirota polynomial does not satisfy the required properties, which led to the impossibility of constructing a three-soliton solution.

Theory of integrable nonlinear equations possessing soliton solutions of a new type - tipper solitons. The operator examines the design proposed by O.I. Bogoyavlensky, and having attractors in the phase space. For output of a new nonlinear equation is used operator structure Li = [L,A] + P(L), that extends the design of lax, L,A - differential operators, P(L) - polynomial 1-th order. As the operator L, one considers the dierential Dirac operator of the first kind. Are defined by necessary and sufficient conditions under which the operator equation is the compatibility condition for the three linear differential equations: the irst is the eigenvalue equation of the operator L on the space variables and the spectral values parametrically dependent on time, the second describes the dynamics of the eigenfunctions of the operator L in a temporary variable, and the third one deines the spectral function. It is shown that the spectral function can have an orbit -stable subvariety or attractor.

The work analyzes the possibility of users mastering brain-computer interfaces based on SSVEP. Two variants of development were studied - stationary, where the user interacted with a monitor, on the periphery of which six light-emitting diodes were located, and mobile, where the user put on modified glasses of augmented reality with an integrated photo-stimulation system. Taking into account the high dispersion of data within the groups, using cluster analysis (K-mean), users were identified who demonstrated inability to learn from the first time and without preliminary training of BCI systems, as well as a number of users demonstrating such opportunities. In this case, two subgroups of such subjects were singled out: for some, the absorption of high frequencies of the а-rhythm is characteristic, however, the low frequencies of both а-rhythm and p-rhythm for these subjects did not give the required quality of assimilation of photostimulation, for others on the contrary, а-rhythm and p-rhythm gave the best results. In the case of AR-glasses, the subjects also gave relatively high results in the low-frequency region of the а-rhythm. The obtained results allow to state that for a significant percentage of users the development of AR-points integrated with synchronous brain-computer systems can be relatively successful already at the irst attempt.
