Substantiation of asymptotical solution of weakly nonlinear hyperbolic system
Lietuvos Matematikos Rinkinys, 2023 A hyperbolic system of first order partial differential equations with small parameter and periodical initial conditions is obtained. The uniformly valid in a long time interval asymptotical solution can be constructed using the averaging along ...

Stable schemes for second-moment turbulent models for incompressible flows
Comptes Rendus. Mécanique, 2023 A stable scheme is proposed in this paper in order to obtain approximate solutions of second-moment turbulent models for incompressible flows with or without thermal transport equation. The analysis of the convective terms, which includes the solution of

An Approach for the Generation of an Nth-Order Chaotic System with Hyperbolic Sine
Entropy, 2018 Chaotic systems with hyperbolic sine nonlinearity have attracted the attention of researchers in the last two years. This paper introduces a new approach for generating a class of simple chaotic systems with hyperbolic sine.

Modeling Heavy-Gas Dispersion in Air with Two-Layer Shallow Water Equations
Fluids, 2020 Computation of gas dispersal in urban places or hilly grounds requires a large amount of computer time when addressed with conventional multidimensional models. Those are usually based on two-phase flow or Navier-Stokes equations.

Modellierung und Derivation in der Phraseologie. Der Fall der hyperbolischen Verbalphraseme im Deutschen [PDF]
Academic Journal of Modern Philology, 2023 The paper deals with selected hyperbolic verbal phrasemes of German and their formation mechanisms. Hyperbolic metaphor and hyperbole are present as semantic rhetorical foundations of the formation of the studied phrasemes and are not only based on ...
