This paper presents an implementation of a modified parallel-pyramidal algorithm for efficient image processing and identification. The method involves the creation of a system model that supports the integration of spatial, temporal and network data to form a dynamic pyramidal-hierarchical network. The paper details vector sorting techniques, Gtransformations for modifying vector elements, and a shifting procedure that facilitates efficient data transformation. The procedures described are integrated into a general data processing sequence that involves iterative application of these methods until the final result is achieved. How the algorithm works is shown in the example of laser beam projection analysis.
This work is aimed at generalizing the methods of laser polarimetry in the case of partially depolarizing optically anisotropic polymer layers. A method of differential Mueller-matrix mapping was proposed and substantiated for reproducing the distributions of the parameters of linear and circular birefringence and dichroism of methyl acrylate layers under various temperature conditions (200 ‒ group 1) and (450 ‒ group 2).
A method of 3D Mueller-matrix reproduction of the distributions of the parameters of linear and circular birefringence and dichroism of partially depolarizing methyl acrylate layers is proposed and substantiated. The dynamics of the change in the value of the statistical moments of the 1st - 4th orders characterizing the distributions of the optical anisotropy parameters of the polycrystalline structure of the partially depolarizing methyl acrylate layer in various "phase" sections of its volume is investigated and analyzed.

The article identifies invariance to image rotation as one of the main problems in image processing. A pyramidal method of generalized spatial processing was proposed as a means to solve the problem specified. The principle of signal processing according to the developed method is presented with an example of its implementation. A comparison of the developed preparation method with the contour preparation method was carried out. As a result, the level of immunity of the developed method to disturbance under Gaussian noise was determined.
The paper presents a model of light passing through translucent materials. The model allows you to effectively model effects that models of the bi-beam reflectivity function cannot provide, such as color propagation within materials and light diffusion across shadow boundaries. The method is effective for anisotropic, highly scattering material that is difficult to simulate using existing approaches. The proposed model combines an exact solution for single light scattering with a point source of approximate diffusion for multiple scattering. An image-based method for determining the optical properties of light-transparent materials is described. The method of data sampling using the ray-tracing method is considered. A method for displaying mirror and glossy surfaces is proposed. The use of aspect measurements for displaying metallic and mother-of-pearl colors of surfaces is considered. The implementation of an intuitive choice of model reflection parameters and a method of appearance refinement independent of the reflection model is proposed. An important aspect of the method is the ability to quickly display homogeneous and pseudo-homogeneous objects, for which it is not necessary to completely scan the volume, reaching the last level of recursion, but it is necessary to ‘skip’ homogeneous areas along the Z coordinate, and immediately calculate the color and overall transparency.
This work is devoted to the design and development of an intelligent information system for predicting the phase stability of solid solutions. Such solutions are used as a base for new luminescent materials. The main trends in the development of intelligent information systems were analyzed that led to a modification of a model for predicting the phase stability of solid solutions. The paper presents a variant review and selection of software design and development methods. Oracle Application Express (programming languages javascript, HTML, pl/SQL) and pl/SQL developer (programming language pl/SQL) were chosen as the software design environment. The paper also contains the analysis of database design methods with the software developed, including a definition of the main functions of the system.
(Ga0.4In0.6)2Se3 thin films were deposited by thermal evaporation technique. Refractive index and extinction coefficient dispersions were obtained from the spectral ellipsometry measurements. The dispersion of refractive index is described in the framework of Wemple-DiDomenico model. The energy pseudogap and Urbach energy were determined from the optical absorption spectrum of (Ga0.4In0.6)2Se3 thin film. Optical parameters of (Ga0.4In0.6)2Se3 thin film and single crystal were compared.

Transformations of geometric objects are described for offsetting. This paper presents the real-time synthesis of highquality images – a method of defining free forms without approximating them with polygons or patches, issues of using perturbation functions for real-time animation of the surfaces of three-dimensional objects. The method for visualizing functionally defined objects adapted for graphics processing units is proposed, as well as methods of transforming the describing function are implemented for geometric operations, such as deformation, displacement, morphology operation, also for nonhomeomorphic objects.
The article presents the determination of limitations of automated speaker recognition systems for critical use. The system, unlike the existing speaker recognition systems, allows predicting the authenticity of the recognition results. It was obtained due to the recognition of matrices with values estimates of interclass relations and interclass distances in the space of classes of speakers, which had fallen to the formulated universal criteria of authenticity evaluation of speaker recognition. The obtained theoretical results were embodied in a modification of the input layer of the threelayered perceptron, which finalizes speaker recognition process by convolution deep neural network.
