CALCULATION OF MAGNETIC CHARACTERISTICS OF TRACTION ELECTRIC ENGINE WITH THE USE OF IMPROVED UNIVERSAL MAGNETIC CHARACTERISTICS

open access: yesNauka ta progres transportu, 2017
Purpose. The article is aimed to develop a technique for calculating the magnetic characteristics of uncompensated traction electric motors (TEM) at any degree of attenuation of excitation based on the approximating expression for improved universal ...

Universalities of earthquake-network characteristics [PDF]

open access: yesChinese Science Bulletin, 2011
The scale-free and small-world properties are studied in detail for the complex earthquake networks constructed from the seismic data sets taken from California (USA), Japan, Iran and Chile. It is found that, in all these geographical regions, both the exponent γ of the power-law connectivity distribution and the clustering coefficient C take the ...

Classification of linearly compact simple Nambu-Poisson algebras [PDF]

open access: yes, 2015
We introduce the notion of universal odd generalized Poisson superalgebra associated to an associative algebra A, by generalizing a construction made in [5].

Transition Events in Butane Simulations: Similarities Across Models [PDF]

open access: yes, 2001
From a variety of long simulations of all-atom butane using both stochastic and fully-solved molecular dynamics, we have uncovered striking generic behavior which also occurs in one-dimensional systems.

Periodic Patterns in Orbits of Certain Linear Cellular Automata [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
We discuss certain linear cellular automata whose cells take values in a finite field. We investigate the periodic behavior of the verticals of an orbit of the cellular automaton and establish that there exists, depending on the characteristic of the ...

Hesse Pencils and 3-Torsion Structures [PDF]

open access: yes, 2018
This paper intends to focus on the universal property of this Hesse pencil and of its twists. The main goal is to do this as explicit and elementary as possible, and moreover to do it in such a way that it works in every characteristic different from ...

The Current State of the Engineering Method for the Optimal Gas-Dynamic Design and Calculation of Centrifugal Compressor

open access: yesEnergies, 2020
In the practice of centrifugal compressor designing, different engineering techniques are widely used because flow motion differential equations cannot be integrated, and Computational fluid dynamics cannot resolve the problem as a whole.

Universal characteristic factors and Furstenberg averages [PDF]

open access: yesJournal of the American Mathematical Society, 2006
Let X = ( X 0 , B , μ , T ) X=(X^0,\mathcal {B},\mu ,T) be an ergodic probability measure-preserving system. For a natural number k k we consider the averages (*)

University Program Characteristics and Education-Job Mismatch [PDF]

open access: yesThe B.E. Journal of Economic Analysis & Policy, 2019
Abstract Over-education has been demonstrated to be frequent and persistent across countries. It often goes together with working in a job not related to the field of study (horizontal mismatch) or in a job that requires lower skills than acquired (skill mismatch).
