Meshcheryakov V.A., Letopolsky A.B., Nikolaev D.I., Teterina I.A.  Designing intelligence control system for excavator’s working equipment and developing reference signals based on fuzzy logical inference

The paper offers the structure of an intelligence control system based on the readings from a lidar, a stereocamera, and IMB sensors. The system’s information flows are described. The control device allows for the information about the actions of a qualified operator. The system comprises neural network decision-making models for selecting an excavation start point and predicting operation parameters, a machine vision subsystem, and a reference signal conditioner. The latter generalizes the information about the required setting and rotation angles of the excavator’s boom, stick, and bucket on the basis of fuzzy logic.

Cherepashkov A.A., Voronin V.N.  Process simulator in the virtual tutorial plant environment

The efficiency of computer-aided design systems is substantially determined by the qualification of CAD specialists. Therefore, their training is a necessary stage in automated system implementation projects. Specialized PLM solutions are developed for training complex CAD personnel in the integrated information environment (IIE) of present-day industrial enterprises. These solutions are implemented on the basis of training centers in the form of training and research virtual enterprises (TRVE). The latter are aimed at intensive task-oriented training and should simulate the IIE of a real-life plant, but they feature significant differences from industrial enterprises in the tools involved, primarily the informational and methodological content. Thus, the TRVE can successfully employ engineering simulators for target-oriented training the skills of of computer-aided design at key phases of design activities in the IIE. The paper discusses a digital procedure of process engineer training at the stage of engineering product workability testing.

Keywords: CAD, training, virtual tutorial plant, integrated information environment, training simulator, product workability testing.

Larionov R.V., Sennikov A.V., Khryashchev V.V.  Forest canopy changes modeling on the basis of remote surface sensing data

The paper presents an algorithm for detecting forest canopy changes during a certain period of time based on satellite images. Forest coupes are considered as canopy changes as the most typical ones for the Russian middle band. The solution proposed is based on the usage of the paired images comprising two satellite pictures of the same territory at different time points. The images are processed by neural network models for obtaining a binary segmentation mask relevant to the previous coupes. A set of 109 paired images was chosen for the experiment. Three neural network models with ResNet-34+U-Net, SegFormer_b5, and SegNeXt_l architectures were applied. For their validation, Sørensen coefficient, F-score, precision, and recall were used. The SegNeXt_l network has demonstrated the best Sørensen coefficient and recall values (0.84 and 0.8 respectively), while the ResNet-34+U-Net has showed the best accuracy and F-score (0.71 and 0.74 respectively).
