Calculation of Optical Characteristics of Multi-Port Single-Mode 1xN Coupler
The optical characteristics of the multi-port 1xN fiber-optic coupler have been studied as function of the optical characteristics of the single-mode 1x2 couplers which it is composed of. Analytical expressions to calculate the optical characteristics of 1xN couplers with consideration of the tolerance deviations of the optical power losses from the nominal ones, and the optical power split between the output ports of the 1x2 couplers have been obtained. In addition, the polarization sensitivity of 1x2 couplers and the scatter of optical power losses in the interconnections of 1x2 couplers within the cascaded 1xN coupler.

Fluctuations of Intensity of a Plane Wave in Environment with Large-Scale Random Heterogeneities
The problem about fluctuations of intensity of a plane wave in environment with large-scale random heterogeneities is resolved, which one is described by a Gaussian correlation function of an index of refraction. On the basis of matching outcomes of calculations conducted by two ways, the dislribution of fluctuations of a field is investigated. Is rotined, that in case of single dissipation the distribution law is normal. At average values of a distance the deviation from the normal law takes place. At large distances the distribution law comes nearer to normal.

Model Atmosphere of CP Star HD101065
The model atmosphere of extremely peculiar roAp star HD101065 is calculated. Accounting of opacity with individualized abundances is executed by "line-by-line" method. Due to lack of data for the REE lines we scaled D.R.E.A.M. data base by ten. The synthetic spectrum and indices in photometric system uvby was calculated: b-y = 0.713, m1 = 0.336, c1 = -0.121. The good agreement between an observation and modeling is obtained.

The algorithm of the relation a signal noise before extraction orders of the echelle spectrum. The heuristic approach for allocation of sites of the image, free from spectral lines is described Is used. Then on the selected sites filter Whittaker is applied to smoothing a signal in each line CCD along an axis of dispersion. Automatic recognition of defects of a matrix and tracks of space beams is in passing made.

Regularization Method in Tasks of Synthesis of a Magnetic Fields
The tasks of synthesis of a homogeneous and linearly varied field in the solenoid are considered in the work. It is shown on examples, that standard methods of the decision of such tasks yield practically unsuitable results. It is shown, that at use of a Tikhonov regularization method the task of synthesis of a field is solved satisfactorily even at small values of currents. The way of calculation of regularization parameter from a condition of a discrepancy minimum on the expanded range of definition of a field is offered.

Interferometric Atmospheric Turbulence Investigation with the Use Solar Light
A method of distant measuring of some optical non-stability and atmospheric turbulence parameters during daytime has been developed. The method is based on application of the interferometer cohercnce with a small angular aperture. Measurements of spatial coherence degree during observations of the direct solar light with the following interferogramms interpretation have been made. Measurements of atmospheric coherence diameter by Fried have been made. It is shown experimentally that light diffusion due to the Sun halo is of a partial coherency. A criterion of optical non-stability based on measurements of light coherence diffusion by Sun halo is proposed. The interferometer can be applied for investigations of light diffusion in turbulent atmosphere.

The String in a Theoretical Physics
Recent progress on string theory in curved space-time reviewed. The string and null-string dynamics in cosmological and black hole space-times is investigated. At is shown that the perfect gas of noninteracting null-strings may be considered as an alternative source of the gravity in the FRW universes with k=0. String dynamics in a curved space-time is studied on the basis of an action functional including the small parameter of rescaled tension. It is shown that in the known equation for geodesic deviation but complemented by a string oscillatory term. These equations are solved for the de sitter and FRW spaces.

On Dynamics of Spectral Atmospheric Transmission Variation in the Crimea
An observational analysis of atmospheric transmission data obtained in the Crimea is made. It is shown that in 1924 - 1932 when there was not practically any industry spectral atmospheric transmission (SAT) data can be assumed as background values. In 1972 - 1990 the anthropogenic loading was maximum. During the period a significant SAT decrease was observed. In the course of "perestroyka" beginning from 1996 SAT values returned to their former background values.
