 The analysis of a new physical method
for measuring the fluid mass flow rate and density This paper gives the preliminary analysis of a new physical method of measuring the fluid’s mass flow rate and density which has been discovered by other authors. The need for exploration and development of the method is defined by its advantages in comparison with other currently existing systems for mass flow rate measuring such as Coriolis flowmeter. The new physical method under consideration is based on measuring the alternating pressure difference which would occur along the flow due to harmonic oscillations of the crosssection area of the pipeline which has flexible walls. It is shown that the new physical method gives the opportunity of simultaneous measurement of mass flow rate and liquid’s density. A mathematical model of the process of nonstationary flow of a liquid is built. The problem of nonstationary flow of a liquid is considered and solved as to be onedimensioned one. The detailed and thorough derivation of the formulae of the mathematical model is performed. Some inaccuracies in formulae permitted by authors of the method are indicated at. The limitations in applicability of the method which had been indicated at by its authors are also essentially weaken. The theoretical examination and approval of conclusions about the applicability of the new method are made. Liquid, density, mass flow rate, pipeline, oscillations, measuring.

 Functional connection (binding), essential elements and rating as tools
for developing a semantic correct scheme for databases The paper considers an ambiguous representation of the subject area reality in data modelling in terms of the relation scheme. There were some attempts to rectify the relational model drawbacks by determining functional dependences among the relation attributes. Those attempts did not tackle the issue completely due to the specific nature of determining functional dependences during standardization of database scheme. The standardization allows eliminating an anomaly of operation updating caused by incorrect models of the subject area associated with the lack of semantic information in the relation model. To improve the representation process of semantic information, which is applied in designing of subject area, the authors suggest using such terms as essential elements and rating. These terms had been scrutinized ever since the hardcopy document workflow, when they were applied to formalize the document contents. To this purpose, the article describes the main components of the relational model in terms of essential elements and rating. For accomplishing aggregation and generalization operations used in developing the relational model and based on the description, the paper identifies formal criteria enabling to reduce the subjective factor while designing a conceptual database scheme. Relation, essential element, rating, aggregation, generalization, functional connection, meaning, semantics, object, nature, components essence.

 Word2vec and BERT language models used for a sentiment analysis of text posts in social networks The paper proposes an original algorithm for the formation of a training sample for a neural network that provides a sentiment analysis of text posts in social networks. A feature of the algorithm is the use of the extended Russianlanguage semantic thesaurus WordNetAffect and the expert dictionary of author’s symbols for expressing emotions. In addition, the paper describes the application of a neural network based on the LSTM architecture to determine the emotional coloring of text messages on a social network using two text vectorization algorithms “word2vec” and “BERT”. As a result of the experiments, an indicator of the accuracy of determining the emotional coloring of messages of 87% was achieved using lemmatization as a text preprocessing algorithm and the BERT algorithm when converting it into a vector.

 Synthesis of the target echo signal with the required parameters to model radar blip and assess tactical characteristics of radars The article deals with the problem of modelling radar blips by reproducing an echo signal of true targets to assess tactical characteristics of radars. A softwaredefined vector generator with incorporated computer and receiver is placed at given angular coordinates and at some distance from radar. The computer generates a digital representation of the waveform; the generator emits a signal corresponding in structure to the radar one. Trigger input of the generator obtains a signal on the period start coming from receiver and computer to ensure interperiod synchronization. The receiver obtains and processes pulses coming from radar. When the strength threshold of received signal is exceeded, the computercontrolled generator receives a signal informing that emitting of prepared echo template has started. As a result, the generator emits an echo signal from the given coordinates, which corresponds to the echo signal of the desired radar blip. The article discusses conditions for generating these blips and characteristics of simulated blips based on characteristics of the equipment used and the radars tested. The author also gives an example of calculating the characteristics of simulated radar blips. Pulse radar, radar blip, radar target, vector signal generator, radar blip profile.

 Software for determining features of a mobile robot’s path with the use of neural networks The article describes an approach to the implementation of a software package for determining the probability of a collision of a mobile robot with obstacles. This approach is based on a neural network model with attention. Key feature is the method of the training dataset generation: the labeling of obstacles and the values of the probability of collision with them is performed not in manual mode, but using a deterministic algorithm that uses the result of semantic segmentation using another pretrained neural network. This method allows to use a poorly detailed description of the external environment for training convolutional neural networks with attention on the example of recognizing obstacles when a mobile robot moves in simulation mode. At the same time, low detail allows to reduce the timeconsuming process of manual data labeling due to automatically generated sampling in the NVIDIA Isaac environment, and the attention mechanism allows to increase the interpretability of the analysis results.

 The study of the stability of aeroelastic systems by linear approximation This paper proposes an approximate method of studying the stability of solutions of nonlinear differential equations with partial derivatives, describing the dynamics of one class of aeroelastic systems. Based on the Galerkin (KrylovKantorovich) method, when presenting the desired deformations in the form (formula), the study of problems for differential equations with partial derivatives for w(x,t) reduces to the study of problems for nonlinear systems of ordinary differential equations for functions (formula) . It is shown that the structure of these systems allows using the known stability theorems by linear approximation. Thus, the study of the dynamic stability of aeroelastic systems is reduced to the study of uniform problems combined by a common approach to solving them. As examples, vibration stability conditions of a pipeline with liquid flowing inside it and a plate streamlined by a supersonic gas flow are obtained. Pipeline, plate, deformation, dynamics, aerohydroelasticity, stability, nonlinear model, partial differential equations.

 Improving the efficiency of statistical control of hydrounit vibrations Some techniques of statistical process control can be applied in investigating an object for likely defects. In this regard, the multidimensional scattering is monitored with the use of a generalized variance algorithm. At fixed time intervals samples of observations are recorded, according to which the values of the determinant of covariance matrix (the generalized variance) are calculated. The corresponding point, falling outside the borders of control chart, indicates the process failure. The test results based on vibration data obtained from the hydraulic unit at the Krasnopolianskaia Hydroelectric Power Station showed that the algorithm of the generalized variance has an insufficient quick response relating to both gradual and spasmodic changes in the scattering level. To make the monitoring process more efficient, the following techniques have been suggested. The first one detects defects by analyzing special kind structures on the generalized variance chart. The second technique applies the warning borders on the chart and the third one implies an algorithm of exponentially weighted moving averages for generalized variance. All the tests revealed that the search for nonrandom structures on the generalized variance chart is most effective for the early detection of changes in the scattering process Generalized variance, average run length, hydraulic unit vibrations, warning borders, exponentially weighted moving averages.

 Simulation and bifurcation analysis
of geotechnical system stability under vibration The automation of control processes for the stability of geotechnical systems is a great challenge involving the development of methods for multivariate analyzing and forecasting the stability with the subject to the nonlinearity of material stiffness parameters. The aim of the study is to improve the efficiency of automated control systems for geotechnical stability by developing an approach to detect negative changes in bifurcation diagrams of vibration displacement parameters of object structures. The authors present a mathematical model of the dynamic behavior of structural elements of an object as an elementary unit of a geotechnical system that describes a response to an external vibration action. An algorithm of bifurcation analysis is presented, which allows authors to determine the initial transition stage of the object structure to an unstable state by the acceleration values of forced oscillations exceeding the model parameters. A bifurcation diagram of stability changes in the structure of object at the displacement resulting from the load increase under vibration action has been constructed. This diagram, which type of codimensionone bifurcations is merging, enabled to determine the critical load values resulting in an unstable state transition of a system due to the influence of a combination of vibration factors. The efficiency evaluation of the proposed approach was carried out by the comparison with the results of construction stability calculations obtained by the use of the dynamic coefficient. The difference between the values of the maximum object displacement without loss of the stability under vibration action, obtained by the standard calculation method and using the developed model, is 32.5%, and it is significant in the theory of structure stability. When exogenous vibration noise is used as a source of a sounding signal, the application of the developed approach in automated control systems for geotechnical stability enable to change the permissible stability thresholds of objects being exploited depending on the level and combination of influencing factors.

 Analysis of the mathematical model of the waste oil purification in a diesel locomotive engine The article analyses a mathematical model of the waste oil purification in the oil system of a diesel locomotive engine. Waste oil purification takes place directly in the engine during its operation, which enables to reduce considerably the time taken to purify, and to decrease the concentration of impurities in the oil. In the proposed system for automatic control of waste oil purification, the main monitored parameters are pressure and temperature of the oil being purified. During analyzing the analytical solution of the system, the authors studied an increase in the concentration of impurity particles, the behavior of particle velocities in the centrifuge, and determined assumptions, within the framework of which the velocity of impurity particles was simulated. The influence of the impurity particle shape in the oil was taken into account in making these assumptions.
