Increasing the reliability of mechanical equipment of industrial enterprises is now increasingly associated with the creation of digital twins and predictive analytics capabilities. In technical diagnostics, one of the tasks is also related to forecasting. The question of how these two directions coincide and diverge is discussed in the article using practical examples of monitoring changes in technical condition, primarily in terms of vibration indicators of mechanical equipment of industrial enterprises. The given examples show possible directions for the development of predictive analytics approaches in real conditions.

The article discusses the main stages and methods of manufacturing semiconductor integrated circuits (ICS), starting with traditional planar technology and photolithography, and ending with modern innovative approaches. The key materials, processes and equipment used in the production of ICS are described, as well as the prospects for the development of this area are analyzed.

The article is dedicated to the classification of unmanned aerial vehicles (UAVs) and their multifunctional use. It examines the types of UAVs, their characteristics, and classification criteria. The advantages of rotorcraft UAVs in civil and military spheres are described, as well as their role in safe operation in challenging conditions. The presented classification is based on areas of application and types of construction, which aids in selecting the appropriate UAV. Further research can enhance the efficiency of developing these devices, for example, by reducing weight and increasing flight range. In conclusion, it is noted that the development of UAVs is a promising direction in science and technology, especially considering the program for their development in Russia until 2030.
