Application of piecewise-linear approximation of probabilistic-time characteristics of queuing systems

open access: yesКосмические аппараты и технологии, 2020
Nowadays many modern industries depend on satellite technologies to a greater or lesser extent. To build such satellite communication systems it is necessary to have estimated parameters of high service quality, one including the information delay time ...

Ising field theory in a magnetic field: φ 3 coupling at T > Tc

open access: yesJournal of High Energy Physics, 2023
We study the “three particle coupling” Γ 11 1 ξ $$ {\Gamma}_{11}^1\left(\xi \right) $$ , in 2d Ising Field Theory in a magnetic field, as the function of the scaling parameter ξ := h/(−m)15/8, where m ∼ T c − T and h ∼ H are scaled deviation from the ...

Features of the potential seismogenic zone of the Ingul and Srednepridneprovsky megablocks of the Ukrainian Shield

open access: yesГеофизический журнал, 2013
Special features of seismogenic zone of the Ingul and MiddleDnieper megablocks of the Ukrainian Shield have been analyzed. Several seismogenic zones with small areas have been subdivided within its limits, which differ by degree of contrast of ...

The red giant branch bump in rotating low-mass stars: Implication for the theory of stellar evolution

open access: yesAstronomy & Astrophysics
Context. The red giant branch bump (RGB bump) is a key diagnostic of an internal stellar structure, yet the impact of stellar rotation– which is a fundamental parameter altering chemical stratification–on its luminosity, amplitude, and morphology remains
