HSE Scientists Train Neural Network to 'Hear' Faults in Electric Motors
Researchers at the AI and Digital Science Institute of the HSE Faculty of Computer Science have developed a new method—the Signature-Guided Data Augmentation (SGDA) framework—that achieves 99% accuracy in motor fault detection and 86% accuracy in fault classification. The application of this approach can reduce industrial equipment repair costs, minimise downtime, and improve production safety. The study results have been published in Engineering Applications of Artificial Intelligence.

'The Humanities Serve as a Conscience'
Maria Mizernaia studies Soviet literature and the history of book publishing. In this interview for the HSE Young Scientists project, she discusses plans to publish a novel about besieged Leningrad, AI-provoked reflections on what it means to be human, and how novels can help satisfy our dopamine hunger.

Is It Possible to Predict a Citys Life Based on the Shape of Its Neighbourhoods?
Is it possible to predict, based on the configuration of streets and buildings, where a café will open or where traffic congestion will occur? Participants in the Spatial Analysis and Modelling of Urban Processes research and study group use open data and machine learning to identify universal patterns. Alexander Sheludkov and Eduard Somov discuss the purpose of comparing cities, the need for new forms of urban statistics, and how open data is transforming approaches to urban studies.

Wave Spectrum of Flowing Drops
Maria Guskova, Shchur L., , in: Supercomputing Book Subtitle 7th Russian Supercomputing Days, RuSCDays 2021, Moscow, Russia, September 27–28, 2021, Revised Selected Papers Series Title Communications in Computer and Information Science.: Springer, 2021.
We simulate the drop-chain movement in the two-dimensional channel using the lattice Boltzmann method coupled with the Immersed Boundary approach. We choose the asymmetric initial state of the drop chain to generate drop oscillations and calculate the wave spectrum. The numerical results coincide qualitatively with the experimental results obtained in the quasi-two-dimensional microfluidic device. ...

Algorithm for Adaptive Mesh Redistribution in Lattice Boltzmann Simulations
Ziganurova L., Shchur L., Lobachevskii Journal of Mathematics 2022 Vol. 43 No. 2 P. 513–518
The Lattice Boltzmann method (LBM) is the alternative approach for hydrodynamic equation solving. Two factors make it a favorite approach nowadays. Firstly, the attractive feature of LBM is that it is intrinsic for parallel simulations due to the linear structure of the algorithm. Secondly, what makes LBM special for the research, it is well applicable to the simulations ...

Simulation of the Particle Dynamics in the Two-Dimensional Poiseuille Flow with Low Reynolds Number
Guskova M., Burovskiy E., Shchur V. et al., Lobachevskii Journal of Mathematics 2022 Vol. 43 No. 2 P. 381–385
A particle moving in the Poiseuille flow in a channel experiences the influence of the velocity gradient and the channel walls. Several effects happen with the particle – velocity retardation, rotation, and migration transversal to the main flow direction. We simulate dynamics of a hard particle in a narrow two-dimensional channel and estimate the variation with the channel width ...

Drop Oscillation Modeling
Shchur L., Guskova M., Communications in Computer and Information Science 2021 Vol. 1131 P. 198–206
The classical problem of oscillations of liquid droplets is a good test for the applicability of computer simulation. We discuss the details of our approach to a simulation scheme based on the Boltzmann lattice equation. We show the results of modeling induced vibrations in a chain of three drops in a closed tube. In the ...

Immersed boundary simulation of drop stability
Guskova M., Shchur L., Journal of Physics: Conference Series 2021 Vol. 1740 P. 1–6
The stability of the quasi-two-dimensional droplet flow is of great importance in microfluidic devices. We check the drop's stability in the square box using the immersed boundary and lattice Boltzmann methods. We implement two-dimensional equations within the immersed boundary approach in the Palabos programming platform. We check the influence of the boundaries on the drop movement. ...

We discuss the applicability of multiphase lattice Boltzmann method for the simulation of the drop oscillation. We demonstrate that the simulation of the single drop excited to the first eigenmode does follow Rayleigh formula. Simulations show no sensitivity to the number of the discrete velocities with D3Q19 and D3Q27 representations of the distribution function in three dimensions. The ...

Exploring the accuracy of the Lattice Boltzmann method
Zagvozdina K., Burovskiy E., Journal of Physics: Conference Series 2021 Vol. 1740 Article 012027
Lattice Boltzmann method is a mesoscopic method used for solving hydrodynamics problems of both incompressible and compressible fluids. Although the method is widely used, reliability of the results is unclear. Therefore, we use the method to solve a fundamental problem with a known analytical solution, the Couette flow. We estimate the accuracy of the simulation ...

Simulation of drop oscillation using the lattice Boltzmann method
Guskova M., Shchur V., Shchur L., Lobachevskii Journal of Mathematics 2020 Vol. 41 No. 6 P. 992–995
We simulate the oscillation of the viscous drop in the viscous liquid. We combine methods of chromodynamics model and Shan-Chen pseudo-potential for the immiscible fluids. We measure the frequency of the first nontrivial eigenmode using the initial ellipsoid form of the drop. Drop oscillates about the equilibrium spherical form of radius $R$. Computed frequency as ...
