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.

Пространственная структура поляризационного джета по данным спутников NORSAT-1 и SWARM

Космические исследования. 2021. Т. 59. № 6. С. 489–497.

In this work, we study the spatial structure of the polarization jet based on data from the NorSat-1 and Swarm ionospheric satellites during a geomagnetic storm. A comparative analysis of the electron density and temperature dependence on the invariant latitude is carried out simultaneously according to measurements of the NorSat-1 and Swarm C satellites during their crossing of the polarization jet. The dependence of the invariant latitude of polarization jet on the auroral geomagnetic activity and on the magnetic local time is confirmed. A double structure of polarization jet is discovered as well as small-scale spatial structures inside the jet with a size of 0.1°–0.2°. It is found that spatial structures are not local and are extended in longitude for at least 2 h of magnetic local time.

In this study, we employ a unique multi‐instrumental approach for a comprehensive examination of Polarization Jet (PJ) (or, another name, Subauroral Ion Drift (SAID)). A diverse set of data is used to assess the connection between the appearance of the inhomogeneous structure of PJ/SAID and its reflection in groundbased observations during geomagnetic activity. Our approach ...

Results are presented from a study of the internal small-scale structure of the polarization jet/SAID using data from different satellites. The minimum size of irregularities and the typical internal composition of a stratified subauroral ion drift (SSAID) are confirmed. A two-peak structure is found that contains two large strata of the polarization jet/SAID. A shift ...

In this paper, the internal structuring of Polarization Jet (PJ)/Subauroral Ion Drift (SAID) is studied. It is shown that PJ/SAID consists of several Polarization Jet Strata (PJS) of electron density and temperature. A new type of phenomena has been discovered called Stratified Subauroral Ion Drift (SSAID), which is a PJ/SAID containing small-scale PJS. Internal small-scale structure of SSAIDs ...
