A DEVELOPMENT OF PERM POLYTECH WILL HELP TO FIND OUT THE NEEDS OF CUSTOMERS USING NEURAL NETWORKS

22 December 2021 127

Product developers and marketers need to understand how customers interact with products. To do this, eye-tracking technologies are used, namely “views direction tracking”.

“Members of the focus group wear special glasses that allow you to find out in which direction and in what sequence the buyers are looking, where their gaze stops longer. This allows you to adjust the design of the interfaces or effectively arrange the goods in the store. But the existing technologies are very expensive and can process data from only one pair of glasses. Therefore, the analysis process requires a long time”, says Alexander Knyazev, developer of the project, programmer and graduate student of the Electrical Engineering Faculty of Perm Polytech .

Unlike its analogues, the domestic development will allow one to study information from several glasses at once. This was achieved due to special algorithms based on neural networks that optimize the image processing process, as well as the use of multicore computing modules.

The attention analysis system includes several glasses with built-in cameras. Two of them are located under the eyes and follow the gaze, and the third camera is located between the eyes and shows the image that a person sees. The glasses transmit information via Wi-Fi to the server where data processing and visualization takes place. The analysis is performed by a system consisting of two parts: glasses and software for them, as well as a server and software for it. The user's computer can be used as a server.

The glasses software will be able to take video from the cameras and process it. Due to this, the direction of view will be displayed on the “picture” that the user sees. The program will be able to send data to the server.

Young researchers from Perm Polytech have already developed a prototype of glasses, a program for “tracking” views and a video analysis system. They presented the technology at the “SMART GUY” competition, where they were highly appreciated by experts and won a grant of 500 thousand rubles for 2 years.

According to the developers, the product will be interesting for implementation in the b2b market, but the technology can be adapted to solve other tasks. For example, with the help of glasses, users will be able to control a computer without a mouse.

TECHNOLOGY OF PNRPU SCIENTISTS WILL RESTORE VALUABLE ELEMENTS FROM PRODUCTION WASTE

Now more and more attention is paid to the process of restoration of nitrogen and phosphorus from industrial and agricultural waste. This is connected with the need to implement the concept of sustainable development of society, based on the circular economy. These elements are biogenic, vital for plant growth. Phosphorus reserves are limited, and the process of obtaining nitrogen is energy-consuming. Potential sources of secondary raw materials are water waste from many industries: the fertilizer industry, pharmaceutical products, semiconductor production and agriculture. The recycling of nitrogen and phosphorus allows not only to reduce the consumption of non-renewable mineral resources, but also to reduce the saturation of natural water bodies with biogenic elements, the excess of which leads to swamping of water bodies and to a decrease in the amount of drinking water. To solve this problem, PNRPU scientists have developed a new approach that has increased the efficiency of extracting ammonium (a form of nitrogen) and phosphate (a form of phosphorus) from industrial waste water to 98-99%. The traditional method does not achieve such results. Moreover, the technology of Perm scientists will make it possible to produce domestically produced long-acting fertilizer based on struvite (a phosphate mineral) and will contribute to the import substitution of foreign analogues.

THE MODEL CREATED BY PNRPU SCIENTISTS WILL PREDICT DEFECTS IN LASER POWDER SURFACING

The method of laser powder surfacing is used to restore worn-out or damaged metal parts. A powerful fiber laser creates a molten weld pool, and then metal powder is automatically fed into it. A common problem that occurs in this process is the deformation of the part, being repaired, under the action of internal stresses. This leads to a defect called warping. One of the aims of developing a technological process for the repair of parts by laser powder surfacing is the prediction of warping defects. The determination of the optimal defect-free surfacing mode for specific parts experimentally is unprofitable due to high financial and time costs and often even impossible. The researchers of the PNRPU together with JSC “UEC-Aviadvigatel” developed a mathematical model for calculating warping during laser powder surfacing to solve this problem. The scientists were able to predict with high accuracy the behavior of the part during the surfacing process thanks to numerical simulations. In the future, the development will help in choosing the optimal set of parameters for repairing parts with the most complicated parts.
