International Russian Smart Industry Conference (SmartIndustryCon)

作者： Georgi Martinov Natalia Martemianova Department of Computer-Architecture Control Systems Moscow State University of Technology "STANKIN" Moscow Russia

The paper considers the problems of manufacturing prototypes of printed circuit boards on bench-type milling machines that require the prompt production of a small batch and correction, if it’s necessary. We used modern tools from third-party manufacturers for the preparation of production and processing of single- and double-layer printed circuit boards on bench-type CNC machines. A technique is proposed that formalizes the process of preparing and verifying part programs and manufacturing printed circuit boards. The methodology was tested and an example of manufacturing a prototype of a printed circuit board for a voltage regulator on a machine with an "AxiOMA Control" CNC system was illustrated.

Trajectory representation learning (TRL) is an intermediate step in handling trajectory data to realize various downstream machine-learning tasks. While most previous TRL research focuses on modeling structured movements in large-scale urban spaces (e.g., cars or pedestrians on streets), this paper focuses on a more challenging scenario of modeling free movement in small-scale social spaces (e.g., children playing in a schoolyard). We present a TRL model, SiamCircle, to process raw trajectories without additional feature extraction to prevent information loss. SiamCircle adopts a Siamese network with Circle Loss to learn trajectory embeddings. Furthermore, SiamCircle employs a data augmentation process to enable self-supervised learning and enrich the input data to address the limited access to high-quality data and ground truth. We evaluate the performance of SiamCircle in downstream tasks using trajectory ranking and clustering performance via seven evaluation metrics collectively. Using an ablation study, we explored the impact of different loss functions on the model’s performance. Accordingly, we selected a 2-D convolutional design with Circle Loss as the best-performing model. In a comparative study, we compared our model against three other baselines. We observed up to 19% improvements in trajectory ranking tasks and achieved the highest average rank in supervised clustering tasks. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM)

作者： Georgi Martinov Petr A. Nikishechkin Department of Computer-Architecture Control Systems Moscow State University of Technology "STANKIN" Moscow Russia

The process of developing a PLC program for controlling the electromechanical units of modern machine tools with computer numerical control (CNC) has been formalized. The architecture of a two-computer CNC system with an integrated SoftPLC is given and the specifics of using the touch operator panel and virtual machine panel are considered. A set of libraries developed in the FBD (Functional Block Diagram) language for controlling the electrical automation units of a turning machine is proposed. An example of controlling the electric automation of a training lathe via the high-speed EtherCAT field bus using relatively inexpensive third-party solutions for servo drives and I/O modules that provide the required accuracy and speed is given.

The evolution of simulation and implementation of P systems has been intense since the theoretical model of computation was created. In the field of software simulation of P systems, the proposals made so far have taken advantage mainly of the parallelism of GPUs, but not of the parallelism of existing multi-core processors. This paper proposes a methodology for simulating P systems using a multi-threaded methodological approach in a multi-core processor. This proposal has been implemented and tested using a simulator programmed in C#, and its correct operation has been tested for confluent and non-confluent systems. The experimental results confirm that the simulator scales well with the number of hardware threads of a mul-tiprocessor. The results obtained suggest that the methodology is valid and that it is worth testing it with more complex systems to find the limits of the methodology. © 2024, The Authors. All rights reserved.

International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM)

作者： Georgi Martinov Alexander Zakharov Department of Computer-Architecture Control Systems Moscow State University of Technology "STANKIN" Moscow Russia

There is a justified need for a cross-platform implementation of an OPC UA server for a CNC system. The available open-source libraries that implement the OPC UA stack have been analyzed, and a solution based on open62541 has been selected. An architectural model for the interaction between the OPC UA server and the CNC system core has been proposed. In addition to the traditional mechanism for obtaining current data values from the CNC system core, the OPC UA server implements a mechanism for working with historical data and a mechanism for controlling the CNC system by sending commands through a control channel via a callback method. Class diagrams illustrating the implementation of these mechanisms have been provided. An OPC UA client has been developed in C# programming language for testing the cross-platform OPC UA server of the CNC system.

The paper deals with the issues of metamerism in multimedia and telecommunication paths. Attention is focused on the end devices of the end-To-end path. A comparison is made in the assessments using traditional coordinate systems for representing colors, and in the coordinates of modern color models CAM16, CAM20u, ZCAM. Numerical differences in the obtained data are shown under the same input conditions. Statistical data of metamer estimates using Mac Adam ellipses are presented. A study was conducted in the work, showing that the spectral compositions of colors can be perceived as one color (based on McAdam's data), but when processed, their number can be different. Based on research, we can say that the differences can reach to 15%. When processing ZCAM models, the number of colors taken into account during transmission will be greater, which makes it possible to reduce the degree of influence of metamerism on color reproduction. © 2022 IEEE.

Spherical evolution (SE) is a recently proposed meta-heuristic algorithm. Its special search approach has been proved to be very effective in exploring the search space. SE is very powerful for optimization, but still has room for improvement due to some promising solutions usually fail to survive into the next generation. To alleviate this issue, we innovatively design a novel lottery-based elite retention strategy and propose a lottery elite spherical evolution algorithm (LESE). To verify the effectiveness of the proposed LESE, we experimentally compare it with the original SE algorithm and other representative meta-heuristics algorithms. We use 30 benchmark functions from the IEEE CEC2017 benchmark as the test set for our experiments. The effectiveness of LESE is demonstrated by analyzing the experimental results from perspectives of solution accuracy, convergence speed, solution distribution, and search dynamics. © 2022 IEEE.

Globally, biomass usage as a supply of non-depletable resources materials used in the production of energy at their rawest state is an issue. Pyrolysis is a method of thermally treating biomass that as a consequence in the formation of liquid, products, both solid and gaseous. Elevated heating is required to transform the complicated composition of the biomass's underlying structure matrix into usable products. Heating with a microwave oven has the potential to become a competitive option. to more traditional methods of heating. Owing to its ease of operation and rapid heating rate, it has recently been widely employed in pyrolysis. The goals of this research are to found the principles of MW-assisted pyrolysis action and to examine some critical issues characteristics of operation that have an influence on the yield of a product. This procedure appears to be governed by a number of operational factors for instance, microwave power and temperature degree, the addition of microwave absorbers and their concentration, initial relative humidity, primary sweep gas flow rate/time spent in residence. © Published under licence by IOP Publishing Ltd.
