Published: December 2019

Abstract
The work is devoted to the use of artificial neural networks to solve the problem of recognition and isolation of objects (cells) in digital micrographs used in the practice of microbiological research. This task is relevant due to a combination of two factors: a large amount of data (hundreds and thousands of photographs, hundreds of objects on each) arising from such studies, as well as the high complexity of manual image processing and the risk of operator errors. To solve the problem of recognition and separation of objects (cells) in digital biomedical micrographs, artificial convolutional neural networks are used. However, in most cases, the use of artificial neural networks requires selection of the network architecture and its training for each task individually. Each time when solving the problem of training the network, it is necessary to collect huge training samples, the more complex the more complex the architecture. The task of cell isolation was solved using a convolutional neural network. The neural network architecture of Mask R-CNN Facebook Research was used. We used a pretrained neural network, retrained in digital micrographs obtained and marked out by the authors. The solution is implemented in Python using TensorFlow, an open source machine learning software library developed by Google. As a result of testing the system, on the available data, the correctness of cell recognition in microphotographs was more than 95%, despite the small size of the digital images used. The applied approach definitely showed its efficiency on the available experimental data and has development prospects in the direction of increasing the size of processed images, increasing recognition accuracy, expanding the composition of secreted objects, working not only with cells, but also with structures in tissues.

Published: December 2019

Abstract
Crimes in the field of bankruptcy of enterprises (organizations) are associated not only with the actions of the leadership, but also with the actions of those who control them, that is, arbitration managers. This necessitates the development and analysis of methods for investigating the crimes of these persons. For this purpose, it is necessary to highlight the signs of offenses and the corresponding penalties existing in the legislation. The analysis revealed the following signs of crime committed by persons controlling the debtor: the process of withdrawing property from economic management by the founder of the enterprise; lack of primary accounting documentation and acts of completion; improper performance of work; disappearance of the head of the controlled organization; failure by the person controlling the debtor to take preventive measures in a pre-bankrupt state; active withdrawal of liquid assets within 3 years preceding the bankruptcy procedure, etc. There may also be signs of fictitious and intentional bankruptcy. If proved, each of these signs is classified according to specific articles of the Criminal, Tax Codes or the Code of Administrative Offenses.

Authors: Alekseev V V , Yakovlev A V , Aminova F E , Sergeev M Ju 
Published: December 2019

Abstract
An approach to the analysis of the topological structure of a system on the basis of the coefficient of structural uncertainty, which allows to assess an ability to modify the structure and compare different topologies, is considered in this paper. The coefficient is defined by the number of transit and end vertices of a graph, which describes the system under consideration. The task is to find a system structure with the greatest value of the coefficient of structural uncertainty. The limits regarding information loss during destruction of one system element with a fixed number of elements is taken into account. The results of research on interelement communication recombination and a number of elements within a level of the hierarchy that both influence the structural uncertainty parameter are provided. A sensitivity analysis of the coefficient of structural uncertainty related to a transit vertex topology is carried out.

Abstract
Long-term operation of wood-drying plants manufactured by the China in the Siberian region made it possible to establish that the basic design of chambers offered by manufacturers often does not ensure the high quality of dry sawn timber and the estimated drying cycle time, especially in winter. Among the measures aimed at improving the quality of drying, the productivity of drying plants while reducing energy consumption, we can single out the direction associated with improving the design of chambers and their heat supply systems. Thus, the relevant areas of improving the energy efficiency of drying lumber is the use of the heat engineering method to improve the functional characteristics of the heat supply systems of the chambers. The analysis of various types of heat supply schemes of chambers with water coolant was made. The advantage of using a heat supply scheme with high-quality control of the coolant flow in the chamber is substantiated. The results of the introduction of design and technological solutions of the heat engineering method are presented, which made it possible to technically re-equip existing and new drying chambers of the China.

Published: December 2019

Abstract
The problem of improving the safety of the use of lifting machinery is particularly relevant for regions where intensive industrial and civil construction is carried out. To date, a significant amount of work has been done, designed at the theoretical level to justify the design and safe operation of lifting machinery. However, the existing methods of control of the total weight of the cargo transported by the lifting machinery are based mainly on the strain measurement methods developed in the second half of the twentieth century. The main disadvantage of systems that implement the strain measurement method is the need to integrate the weighing module directly into the design of the lifting machinery. A significant number of accidents of hoisting machines indicates the fuzzy operation of the protection systems of hoisting machines from overload, made on the basis of tensometric methods. As shown by the results of studies in the operation of various types of electric motors under load torque fluctuations occur at the rated speed. The use of this pattern allows weighing the cargo by the dynamic method transported by a lifting machinery. This article is devoted to the development and scientific and technical substantiation of the method of dynamic control of the weight of the cargo transported by the lifting machinery, based on the analysis of the dynamics of the angular accelerations of the rotor of the electric motor of the lifting drive.
