CONTROL OVER «BRUSH-COMMUTATOR» SPARKING IN DC MACHINES USING OPTOELECTRONIC SPARKING ANALYZER
Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2005 A «brush-commutator» contact is one of the factor that affects commutative properties and commutation. The paper presents a new method for estimation of a commutation.

n-complete crossed modules and wreath products of groups
Journal of New Results in Science, 2021 In this paper we examine the $n$-completeness of a crossed module and we show that if $X=(W_1,W_2,\partial)$ is an $n$-complete crossed module, where $W_i=A_i wr B_i$ is the wreath product of groups $A_i$ and $B_i$, then $A_i$ is at most $n$-complete ...

On commuting and semi-commuting positive operators [PDF]
Proceedings of the American Mathematical Society, 2014 Let K K be a positive compact operator on a Banach lattice. We prove that if either [ K ⟩ [K\rangle or ⟨ K ] \langle K] is ideal irreducible, then [ K ⟩ = ⟨ K ] = L +

Commutators and Squares in Free Nilpotent Groups
International Journal of Mathematics and Mathematical Sciences, 2009 In a free group no nontrivial commutator is a square. And in the free group F2=F(x1,x2) freely generated by x1,x2 the commutator [x1,x2] is never the product of two squares in F2, although it is always the product of three squares.

On monogenic functions defined in different commutative algebras [PDF]
arXiv, 2018 A correspondence between a monogenic function in an arbitrary finite-dimensional commutative associative algebra and a finite set of monogenic functions in a special commutative associative algebra is established.

Magnitude control of commutator errors [PDF]
, 2006 Non-uniform filtering of the Navier-Stokes equations expresses itself, next to the turbulent stresses, in additional closure terms known as commutator errors.

Characterization of the Spin and Crystal Field Hamiltonian of Erbium Dopants in Silicon
Advanced Quantum Technologies, EarlyView.Erbium in silicon is a promising platform for scalable quantum information processing, as it combines optically addressable spins in the telecom regime with the mature, wafer‐scale nanofabrication techniques available for silicon. In this work, the point symmetry and magnetic interaction of two particularly promising erbium sites are investigated.

Gröbner-Shirshov Bases for Commutative Algebras with Multiple Operators and Free Commutative Rota-Baxter Algebras [PDF]
arXiv, 2013 In this paper, the Composition-Diamond lemma for commutative algebras with multiple operators is established. As applications, the Gr\"obner-Shirshov bases and linear bases of free commutative Rota-Baxter algebra, free commutative $\lambda$-differential algebra and free commutative $\lambda$-differential Rota-Baxter algebra are given, respectively ...

Photon Number Coherence in Quantum Dot‐Cavity Systems can be Enhanced by Phonons
Advanced Quantum Technologies, EarlyView.Photon number coherence (PNC) is important for quantum cryptography. Because of that, the PNC within a quantum dot‐cavity system is investigated theoretically. Phonons, which interact with the quantum dot, surprisingly do not necessarily decrease PNC. It is demonstrated that it is possible to optimize other figures of merit without significant penalty ...
