Full text linkThe object of research: morphological and cultural characteristics of micromycetes: yeast Saccharomyces cerevisiae and mycelial fungi Mucorracemosus grown on agar medium.The subject of research: flax seed suspension, ultrafine powder of double oxide of divalent and trivalent ferrum, micromycetes: yeast Saccharomyces cerevisiae and mycelial fungi MucorracemosusInvestigated problem: ensuring the bacteriostatic properties of raw materials and obtaining products with an extended dates of expiry.The subject in scientific results: the impact of nanoparticles (NP FeO×Fe2O3) on the bacteriostatic (protective) properties of flax seeds against fungal infections has been studied and the dependence of bacteriostatic properties on the amount of nanomagnetite has been determined. The ability of nanomagnetite to improve the bacteriostatic properties of flax seeds has been proven: addition of 0.1 %; 0.15 %; 0.2 % of nanomagnetite suppresses the development of microflora (micromycetes) in flax seed samples by 8–20 times. A reduction in the number of micromycetes (yeast Saccharomycescerevisiae and mycelial fungi Mucorracemosus) by 8–10 times and the size by 10–20 times was established compared to the control.
The rational content of nanoparticles (NPs FeO×Fe2O3–nanomagnetite) has been determined as 0.15 % of the weight of the recipe mixture.
The proposed mathematical model makes it possible to predict the effectiveness of using NP FeO×Fe2O3 – nanomagnetite to inhibit the growth of mycelial fungi to ensure the bacteriostatic properties of raw materials, in particular, flax seeds.

Convolutional neural networks for modeling and forecasting nonlinear nonstationary processes
Full text linkThe object of research. The object of research is modeling and forecasting nonlinear nonstationary processes presented in the form of time-series data.
Investigated problem. There are several popular approaches to solving the problems of adequate model constructing and forecasting nonlinear nonstationary processes, such as autoregressive models and recurrent neural networks. However, each of them has its advantages and drawbacks. Autoregressive models cannot deal with the nonlinear or combined influence of previous states or external factors. Recurrent neural networks are computationally expensive and cannot work with sequences of high length or frequency.
The main scientific result. The model for forecasting nonlinear nonstationary processes presented in the form of the time series data was built using convolutional neural networks. The current study shows results in which convolutional networks are superior to recurrent ones in terms of both accuracy and complexity. It was possible to build a more accurate model with a much fewer number of parameters. It indicates that one-dimensional convolutional neural networks can be a quite reasonable choice for solving time series forecasting problems.

Cutting forces when grinding parts from martensite aging steels with highporous abrasive, borazon and diamond wheels
Full text linkObject of research. The article investigates the cutting forces when grinding martensitic-aging steels with highly porous grinding wheels.
The problem to be solved is the regularities of the change in the magnitude of the cutting forces when grinding maraging steels with highly porous CBN wheels.
Main scientific results. The studies were performed on martensiticaging steel H8K18M14. As a result of the experiments, it was found that when grinding wheels made of materials such as electrocorundum, CBN (borazon) and diamond, a significant role is played by the values of the cutting force, which increase during processing.
During the experiment it was found out: the cutting forces Py and Pz in the width of the allowable modes, which are most often used in circular and flat grinding, can reach the following values: with the structure of the wheel 26 come to values from 2.714N to 30.721 and with the structure of the wheel 40 come to values from 2.49N to 28.185N.
Reducing the grain size of the wheel, let’s obtain the effect of increasing the energy costs of the grinding process, by increasing the magnitude of the cutting forces.
If to compare the cutting forces that occur when grinding different wheels, it is possible to note the following: in comparison with electrocorundum wheels when using wheels with KNB cutting forces are reduced by 20-25 %, and when grinding with diamond wheels, the effect of cutting forces is reduced by 25 - 30 %. When grinding with highly porous wheels, the cutting force is 15-20 % higher than when grinding with wheels of normal porosity.
The area of practical use of research results-grinding technology for maraging steels.
Innovative technological product – relationship between processing modes and the magnitude of cutting forces when grinding maraging steels.
