The paper deals with blind deconvolution algorithm for the images distorted in the vector channel. The obtained algorithm is compared to one of the most effective pre-existing algorithms. The article shows the results of the simulation and the images of different noise levels restored by each of the algorithms.

The impact of micrometeoroids and space debris on materials and structural elements of the open space vehicles in long-term use leads to degradation of their characteristics. For the experimental simulation of the meteor and human impact on the surface of optical glass is designed and manufactured unit, which includes an electro-accelerator system of registering and processing information. Experimental stand allows the following tasks: identify the main mechanisms leading to the degradation of materials; determination of the experimental curves of degradation characteristics of the mass and velocity of the particles.

The article presents a comparative analysis of three approaches to the calculation of standard solutions for the Tikhonov regularization problem: Based on the normal system of equations, singular value decomposition and extended the normal system. Comparison is carried out in these classes of problem: joint defined systems with ill-conditioned matrix, systems in which the right-side vector is set with an inaccuracy and the system of deficient engine rank.

The theory, design parameters and construction details of a cyclic accelerator in Zvolen accelerate charged microparticle diameter 0.1 ... 10 mm up to velocities of 25 km / s are presented. The total effective accelerating voltage of 5 MV. The essential difference from the accelerator of the existing is that all of the drift tube of the dynamic circuit made the same, and in-phase motion of the particle to the voltage across the drift tubes is accomplished by forming the accelerating voltage as a function of particle velocity and its specific charge, as well as in cyclic accelerator circuit.

This article provides a brief description of existing TOF ion focusing methods in mass spectrometers, we compare the mass spectrometer using ion mirrors with linear and nonlinear distribution of axial potential. Researchers have considered the basic equations for the calculation of the ion-optical systems, the results of simulations of two types of spectrometers, the results of calculations depending on the resolution of the instruments of mass and initial energy spread of ions. We derive the advantages of mass spectrometers with nonlinear distribution of axial potential ion mirrors based on these obtained data.
