The article discusses the task of detecting malicious attachments in emails used in targeted cyber attacks. An approach based on the combined use of text and file attributes of messages using machine learning methods is proposed. The models of logistic regression and the random forest method are compared according to the main classification quality metrics. Experiments on a synthetic dataset have shown that logistic regression provides a higher completeness of detection of malicious attachments, whereas a random forest is characterized by a higher classification accuracy. The results obtained confirm the effectiveness of the hybrid approach and the possibility of its integration into email protection systems.

In the article, a numerical study of the heat sink with a change in the aggregate state of the oil is carried out. Simulation was carried out in Ansys Fluent CAD for two modes, static - with constant heating of the oil at 340K and dynamic, at which the heating temperature varied with time from 340K to 270K. Heat transfer in the event of a change in the aggregate state of a substance is widely used in cases where it is necessary to achieve the maximum efficiency of heat exchange. In this case, the energy is expended on the phase transition of the substance, for example, to evaporation from the liquid phase. The advantage of the heat-sink design described in this work is a rather high rate of heat transfer, greater resistance to various influences, including mechanical ones, which is primarily ensured by the simplicity of construction, eliminating the drawbacks of classical designs, which are cumbersome (the presence of an external cooling circuit ) and the limited rate of heat transfer.

Changes in the structure of industry, caused by the process of the formation of a new phase of the feasibility of the global industry, and based on the creation and implementation in all areas of the industry of new technologies that provide higher added value. The development of new promising sectors of the feasibility stage of development should be accompanied by the creation of a new institutional structure to date, capable of providing a maximum concentration of innovation potential in terms of industrial production reshoringa. One of the most effective forms of institutional support for the development of high-tech manufacturing industries are state corporations to ensure the generation of technical, scientific and economic potential, the formation of a full cycle of "science-production" in a structural transformation of the industrial sector.
