Often, the description of the physical effect in the 'primary' sources of information (patent documents, journal articles of a physical profile, dissertations in physics) contains graphs of dependencies linking the physical quantities of the input and output impacts of the physical effect (PhE). The analysis of this information and its use to expand the description of the physical effect is an urgent task. A modification of the model for describing the physical effect was carried out, taking into account the graphical representation of the functional dependence of the physical quantities of the PhE. CNN, LSTM, Visual Transformer (ViT) neural networks and machine learning methods of Naive Bayes, SVM have been tested in relation to classification and recognition tasks on images of dependency graphs. A comparative analysis of the approaches (accuracy of definition, complexity of data preparation, fault tolerance, equipment requirements) was carried out using criteria of precision, recall, F-measure, AUC-ROC. © 2024 IEEE.

Currently, patent documents contain graphic images of device drawings, graphs, chemical and mathematical formulas, and the formulas often need to be recognized and brought to a unified standard. This work analyzes graphic images extracted from the descriptions of FIPS Rospatent patents. Thematic filtering of mathematical and chemical formulas contained in patent documents and their recognition is provided. The theoretical value lies in the developed patent parsing algorithms in the *** system;recognition of chemical and mathematical formulas among graphic patent images;converting graphic images of chemical formulas into SMILES format;converting graphic images of mathematical formulas into LaTeX format. The practical significance of the work lies in the developed software module for analyzing graphic images from patent documents. The scope of the developed module is the study of patents and the reduction of graphic images to a unified standard for solving patent examine problems. © 2024 IEEE.

In the paper, hardware and software of the Arduino based pure sine wave inverter with overload and overheating protection have been developed. The inverter constantly monitors the consumption current, the battery voltage, the temperature of the power switches (radiator) and, if their parameters are normal, forms a sinusoidal voltage of 230 V, 50 Hz at the output of the inverter, similar to the network voltage. The inverter provides the display of information on the LCD screen about current and power consumption, battery voltage, temperature of the inverter power switches, as well as display of emergency icons when the permissible operating parameters are exceeded. The inverter generates sound and visual warning messages with LED indicators and buzzer. The inverter can be used as a lightweight low-power 100 W network inverter with sine-wave voltage for autonomous power supply of low-power electronics. © 2024 IEEE.

A fuzzy collaborative forecasting approach based on XAI applications for cycle time range estimation

Estimating the cycle time ranges of jobs is a critical task in a factory. this study proposes a fuzzy collaborative intelligence (FCI) approach to improve the precision of cycle time range estimation. In the proposed methodology, a DNN is first built to accurately predict the cycle time of a job. A random forest (RF) is then constructed to explain the DNN. Each decision tree of the RF is fuzzified to estimate the cycle time ranges of the jobs learned by the decision tree. A fuzzy collaboration mechanism is also established between decision trees to narrow the cycle time ranges. The proposed methodology is novel because the RF is not applied to predict job cycle times but used to explain and fuzzify the DNN without solving complex nonlinear programming problems. The proposed methodology has been applied to a real case. According to the experimental results, the FCI approach improved the estimation precision by 18%. © 2023 Elsevier B.V.

Studies have been conducted on anodized aluminum oxide (AAO) nanomatrices manufactured by SmartMembranes (SM) (Germany) and InRedox (USA). An X-ray fluorescence analyzer determined the quantitative and qualitative composition of AAO matrices. It is shown that the AAO matrices have a large transparency window (250 - 2750 nm) and the dependence of the second harmonic generation (SHG) signal on the pore size. The parameters of the porous structure of the samples were estimated by isothermal processes of nitrogen adsorption/desorption at its boiling point (T = 77 K). © 2024 IEEE.

In the paper, the model and prototype of the AC stabilizer have been developed based on the AVR ATmega328P microcontroller. The block diagram of the device, the electronic circuit and the algorithms of the system operation have been developed. In particular, the algorithm includes software in C in the Arduino IDE. The AC voltage stabilizer is designed using the modular principle, which makes it possible to quickly upgrade. The AC voltage stabilizer makes it possible to maintain the supply voltage on the load within acceptable limits with significant deviations, has the ability to adjust the voltage range of the network to operate the stabilizer, manual adjustment potentiometers.
