Power Comparisons of EDF Goodness-of-Fit Tests
(Сибирский федеральный университет. Siberian Federal University, 2023-06)In this article, the power of common goodness-of-fit (GoF) statistics is based on the em- pirical distribution function (EDF) where the critical values must be determined by simulation. The statistical power of ... -
Definition of Lifetime due to Wave-Particle Interactions for the Pitch Angle of 90 Degrees
(Сибирский федеральный университет. Siberian Federal University, 2023-06)One of very important, but still it is not enough the investigated problems in the theoretical physics of the Earth’s magnetosphere is the definition of lifetime of the charged particles due to wave- particle interactions. ... -
The Fredholm Navier-Stokes Type Equations for the de Rham Complex over Weighted H¨older Spaces
(Сибирский федеральный университет. Siberian Federal University, 2023-06)We consider a family of initial problems for the Navie–Stokes type equations generated by the de Rham complex in Rn [0; T], n > 2, with a positive time T over a scale weighted anisotropic H¨older spaces. As the weights ... -
Identities Related to Homo-derivation on Ideal in Prime Rings
(Сибирский федеральный университет. Siberian Federal University, 2023-06)This study aims to investigate the commutativity of a prime ring R with a non-zero ideal I and a homo-derivation # that satisfies certain algebraic identities. We also provided some examples of why our results hypothesis ... -
Soft Tripled Coincidence Fixed Point Theorems in Soft Fuzzy Metric Space
(Сибирский федеральный университет. Siberian Federal University, 2023-06)In this work, we are going to prove the fixed point theorems (FPT’s) for the existence and uniqueness of soft tripled coincidence point for contractive maps in the setting of soft fuzzy metric space (SFMS). We have also ... -
On the Calculation of the Poiseuille Number in the Annular Region for Non-isothermal Gas Flow
(Сибирский федеральный университет. Siberian Federal University, 2023-06)A slow longitudinal non-isothermal gas flow in the annular region caused by small pressure and temperature drops across a long micro-channel is considered in the paper. A method for calculating the values of the Poiseuille ... -
MD Investigations of of Heat Flow throw Interfaces in 1D Systems
(Сибирский федеральный университет. Siberian Federal University, 2023-06)Molecular dynamic calculations (MD) of heterogeneous 1D periodical systems are presented. It is proposed the new technique of direct calculations of thermal conductivity, where there is only one thermostat in one piece ... -
Boubaker Operational Matrix Method for Fractional Emden-Fowler Problem
(Сибирский федеральный университет. Siberian Federal University, 2023-06)In this paper the singular Emden-Fowler equation of fractional order is introduced and a computational method is proposed for its numerical solution. For the approximation of the solutions we have used Boubaker polynomials ... -
On the Sharp Estimates for Maximal Operators
(Сибирский федеральный университет. Siberian Federal University, 2023-06)The paper deals with boundedness problem for the maximal operators associated with hypersurfaces in the space of square integrable functions. A necessary condition for boundedness is given in the case of one nonvanishing ... -
Parametrizations of Limit Positions for the Discriminant Locus of a Trinomial System
(Сибирский федеральный университет. Siberian Federal University, 2023-06)The paper deals with the discriminant of the reduced system of n trinomial algebraic equa- tions. We study zero loci of truncations of the discriminant on facets of its Newton polytope. The basis of the study is the ... -
On the Effect of Delays in Self-oscillating System with Ex- ternal Influence
(Сибирский федеральный университет. Siberian Federal University, 2023-06)Self-oscillating system that interacts with energy source of limited power is considered in the presence of external force and joint action of delays in damping and elasticity. On the basis of the direct linearisation ...
