In the work describes the extreme filtering method and the author's approaches that allow adapting it to work in real time: frame-by-frame processing and the method with signal loading. Further, solutions are presented that can be used to implement the above on real devices. The first solution is to use the Multiprocessing library for the Python language. The second approach involves creating a client-server application and sending asynchronous POST requests to implement the frame-by-frame signal processing method. The third method is also associated with the development of a client-server application, but with the WebSocket protocol, not HTTP, as in the previous approach. Then, the results are presented, and conclusions are made about the suitability of the author's approaches and solutions for working on real devices. It is noted that the solution based on the use of the WebSocket protocol is of particular interest. This solution is suitable for both the frame-by-frame signal processing method and the method with value loading. It is also noted that all approaches proposed by the author are workable, which is confirmed by the time values ​​and the coincidence of the graphs.

In the practice of hydraulic engineering construction, especially in mountainous and foothill areas, quite often there are conditions under which it is economically advantageous to build a dam reservoir from heterogeneous local materials with different filtration characteristics. As a rule, in such areas near the site of the future dam there is not enough homogeneous construction soil that meets all the requirements. However, it is possible to find soils that differ in water permeability, but in sufficient quantity for the construction of the body of this dam.

This paper presents a simulation of square bar extrusion using the finite element method in QForm software. The sequence of simulation stages is described and verified using an example of extruding AD31 alloy. The geometry of the extrusion tool (die) was improved to reduce material damage and eliminate profile distortion. It was found that rounding the corners and adding a calibrating section to the die provides improved performance. The analysis of metal heating from plastic deformation is also provided. The study highlights the importance of computer modeling for optimizing tools and increasing the efficiency of the metal forming process. Specifically, the initial and final die geometries were compared to assess the impact on product properties. Recommendations are provided for using simulation in the practice of developing metal forming process technologies. The benefits of using QForm software over alternative solutions are highlighted, including access to a comprehensive material database and robust technical support.
