The article discusses the structure and principle of operation of an improved centrifugal unit for mixing bulk materials. A special feature of which is the ability to control mixing modes. Due to its design, the selection of a rational position of the bump makes it possible to provide such conditions for the impact interaction of particle flows, in which a high-quality homogeneous mixture of components is formed, the particles of which have different sizes, shapes and other parameters. To characterize the resulting mixture, the coefficient of heterogeneity was used, the conclusion of which is based on a probabilistic approach. A computational scheme of the rarefied flow formation process is given. An expression is derived for calculating the coefficient of heterogeneity when mixing bulk media, the particles of which have different sizes, shapes and other parameters. The research conducted in the article allows not only to predict the quality of the resulting mixture, but also to identify the factors that have the greatest impact on achieving the required uniformity.

The article discusses the main methods of carbon black granulation, and compares the results with an existing industrial installation. The granulation process is necessary to convert powdered carbon black into homogeneous granules in order to simplify its further transportation and use. Despite the wide variety of granulation methods, there are problems with the uniformity of granules, equipment wear, and the formation of stagnant zones. As a result of the experiments conducted on the laboratory granulator described in the article, photos of the results are provided. Each of the methods used has a description of stagnation zones, which allows us to conclude that the most efficient method is to convert powdered carbon black into granules.

The article discusses the basic model of the formation of an emulsion layer on a rotating cylinder. Special attention is paid to the study of the influence of various parameters on the internal characteristics of the emulsion formation process. A mathematical description of the displacement layer is given and functional dependencies between the parameters characterizing the emulsion formation process are derived. Based on experimental data, the qualitative influence of "internal" and "external" factors on the formation of the emulsion layer has been studied. The result of the study were graphs, analyzing which the following conclusions can be drawn. An increase in the viscosity of the emulsion leads to a decrease in such parameters as the boundary of the fracture region of a more viscous liquid layer adjacent to the surface of the rotating cylinder, the viscosity of the emulsion in the transition layer, but there is an increase in the consumption of the emulsion. It is also established that the growth of the complex of "external" parameters leads to a decrease in all internal parameters during the formation of the emulsion. The research conducted in the article will help to take into account the obtained dependencies when calculating the operating and design parameters of devices.

This article is considered Immunological method of the railway vehicle's parts localization based on the clonal selection algorithm. The advantage of this approach is the use of one-class support vector machine, which allows classifier training with only positive examples. The suggested approach significantly reduces complexity and formation of the training sample set. Immunological localization method has high performance characteristics due to the hybrid application one-class support vector machine and clonal selection algorithm. This allows to optimize the procedure of objects finding in the analyzed image

Developed a rapid method for evaluation of the homogeneity of mixtures hardly separated granular materials, the analysis of which is the use of known methods is impossible or time-consuming. The method is based on the separation of mixture components by color using computer processing of pictures of her samples. To implement the developed computer program that can calculate the values of the coefficient of heterogeneity of the mixture, as well as other dispersion parameters.

This paper proposes a new approach to railway vehicles localization based on image processing method consists in the recognition of the railway car coupler on the graphical images obtained by cameras of versatile automatic recognition system for railway cars’ numbers (versatile ARS-RCN system). A model based on the recognition of the coupling of the real-valued negative selection algorithm with variable-sized detectors was developed. Computational experiments that showed the effectiveness of developed model in comparison with the classical support vector machine on real data collected on one the versatile ARS-RCN system object were performed. The effectiveness of the proposed approach in the duplicated mode (using two cameras) and in combination with the basic method of localization of mobile units on the basis of inductive sensors passing wheels was showed.

This paper presents a new neuroimmune-based method for block recognition of railway rolling stock inventory numbers. The advantage of such approach is  classification without using of negative samples. Developed technique combines segmentation and classification that allows to achieve higher noise robustness, segmentation possibility of fuzzy combined digits which have different fonts and typeface, and invariance of existing numbers to scale changes. Proposed method allows to constantly increase the training set for the improvement in classification accuracy by new committee classifiers statistics due to the data reduction property achieved by using the immune clustering mechanism. Research results were implemented in the software system of automatic recognition of cars numbers (ARNV), which is operated on the JSC Russian Railways.
