How to Assess Students Knowledge in the Age of AI
A researcher at HSE University has proposed a flowchart to help lecturers decide how to assess students who use artificial intelligence. It shows where the use of AI should be restricted and where it can be incorporated into the learning process. The article has been published in IT Professional.

‘Balkan Hospitality Opens Doors: Studying Dialects on the Verge of Extinction
You cannot study spoken dialects from books. Instead, you need to go to a village, seek out its elders, and earn the trust of local residents before you can record hours of spontaneous stories. This is how Natalia Muravleva, Associate Professor at the Faculty of Humanities, conducts her research. Her internship in Serbia continued her long-standing study of dialects spoken by Macedonian settlers. In this interview, she discusses how diaspora cultural centres help researchers reach informants, why native speakers need to be interviewed only in their own language (otherwise, as she puts it, they may 'break'), and how a single field season helped her finalise her monograph. She also shares warm memories of autumn in Belgrade and of colleagues with whom grammar can be discussed in three languages at once.

Scientists Train Neural Network to Generate Process Plans from 3D Models
Researchers at the HSE FCS AI and Digital Science Institute have developed CAD2TechSpec, a framework that converts 3D models of mechanical parts into machining process plans—step-by-step instructions for machine tools. The solution aims to reduce the time required for the design and preparation of technical process documentation in mechanical engineering, aircraft manufacturing, and other high-tech industries. The study findings have been published in PeerJ Computer Science.

On a conservative finite-difference method for 1D shallow water flows based on regularized equations

P. 3–18.
Zlotnik Alexander, Gavrilin Vladimir
In press

We deal with the 1d shallow water system of equations and exploit its special parabolic regularization satisfying the energy balance law. We construct a three-point symmetric in space discretization such that the discrete energy balance law holds and check that it is well-balanced. The results of numerical experiments for the associated explicit finite-difference scheme are also given for several known tests to confirm its reliability and some advantages. The practical error behavior is also analyzed.

Ioann Melnikov, Pelinovsky E., Physics of Fluids 2024 Vol. 36 No. 7 Article 076609
A method for the transformation of linear shallow water equations based on a generalization of the Carrier–Greenspan transform, well known in the theory of wave rolling on a flat slope, is presented. Thanks to it, the initial equations for waves over arbitrary bathymetry are reduced to a wave equation, from which both the displacement of ...

Properties of regularized equations for barotropic gas mixtures
Fedchenko A., Journal of Mathematical Sciences 2023 Vol. 270 No. 6 P. 815–826
We consider regularizations of systems of equations for a multicomponent gas mixture dynamics in the barotropic multi-velocity and one-velocity cases. Energy balance equations are derived for them. For the system of equations in the one-velocity case, the system linearized on a constant solution is studied, and, for the weak solutions to the initial-boundary value problem with ...

Robust computations of runup in inclined U-shaped bays
Hartle H., Rybkin A., Pelinovsky E. et al., Pure and Applied Geophysics 2021 Vol. 178 No. 12 P. 5017–5029
We present an exact analytical solution for computations of runup in constantly inclined U- and V-shaped bays. The provided solution avoids integration of indefinite double integrals in (Rybkin et al., Water Waves 3(1):267–296, 2021) and is based on a simple analytic expression for the Green’s function. We analyze wave runup in parabolic and certain V-shaped bays, for which a particularly wide ...

On conditions for weak conservativeness of regularized explicit finite-difference schemes for 1D barotropic gas dynamics equations

We consider explicit two-level three-point in space finite-difference schemes for solving 1D barotropic gas dynamics equations. The schemes are based on special quasi-gasdynamic and quasi-hydrodynamic regularizations of the system. We linearize the schemes on a constant solution and derive the von Neumann type necessary condition and a CFL type criterion (necessary and sufficient condition) for weak conservativeness in L2 for ...

On the energy dissipative spatial discretization of the barotropic quasi-gasdynamic and compressible Navier-Stokes systems of equations in polar coordinates
Zlotnik A., Russian Journal on Numerical Analysis and Mathematical Modelling 2018 Vol. 33 No. 3 P. 199–210
The barotropic quasi-gasdynamic system of equations in polar coordinates is treated. It can be considered a kinetically motivated parabolic regularization of the compressible Navier-Stokes system involving additional 2nd order terms with a regularizing parameter $\tau>0$. A potential body force is taken into account. The energy equality is proved ensuring that the total energy is non-increasing ...

Hydrodynamical aspects of the formation of spiral–vortical structures in rotating gaseous disks
Elizarova T.G., Zlotnik A.A., Istomina M. A., Astronomy Reports 2018 Vol. 62 No. 1 P. 9–18
This paper is dedicated to numerical simulations of spiral–vortical structures in rotating gaseous disks using a simple model based on two-dimensional, non-stationary, barotropic Euler equations with a body force. The results suggest the possibility of a purely hydrodynamical basis for the formation and evolution of such structures. New, axially symmetric, stationary solutions of these equations ...

О балансе энтропии для одномерной гиперболической квазигазодинамической системы уравнений
Злотник А.А., Четверушкин Б. Н., Доклады Российской академии наук. Математика, информатика, процессы управления (ранее - Доклады Академии Наук. Математика) 2017 Т. 474 № 1 С. 22–27
Выполняется анализ баланса энтропии для одномерной гиперболической квазигазодинамической (ГКГД) системы уравнений. В частности, выясняется, что при регулярных режимах течения поведение энтропии в основном определяется слагаемыми естественной вязкости и теплопроводности. Отличие в производстве полной энтропии по сравнению с уравнениями Навье-Стокса вязкого сжимаемого теплопроводного газа составляют слагаемые порядка $O(\tau^2)$, где $\tau$ - параметр релаксации. Дополнительно для более ...

We derive new axially symmetric stationary solutions to the barotropic Euler equations with a body force in the isentropic and isothermal cases. They are used as the initial distributions in the related non-stationary problem. Basing on a quasi-hydrodynamic approach, we perform numerical experiments on the development of small initial perturbations of the azimuthal velocity and ...
