Recognition of Acoustic Signals of Commutator Motors
Most faults can stop a motor, and time is lost in fixing the damaged motor. This is a reason why it is essential to develop fault-detection methods. This paper describes the acoustic-based fault detection of two commutator motors: the commutator motor of

Eulerian dynamics with a commutator forcing [PDF]
: We study a general class of Euler equations driven by a forcing with a commu-tator structure of the form [L; u]() = L(u)L()u, where u is the velocity eld and L isthe \action which belongs to a rather general class of translation invariant operators ...

Generating Sets and a Structure of the Wreath Product of Groups with Non-Faithful Group Action
Given a permutational wreath product sequence of cyclic groups, we investigate its minimal generating set, the minimal generating set for its commutator and some properties of its commutator subgroup.

Commutator identities on associative algebras and integrability of nonlinear pde's
It is shown that commutator identities on associative algebras generate solutions of linearized integrable equations. Next, a special kind of the dressing procedure is suggested that in a special class of integral operators enables to associate to such ...

Writing commutators of commutators as products of cubes [PDF]
It is known that commutators of commutators can be written as products of cubes, with the current upper bound on the number of cubes being 60. We discuss how proofs extracted via coset enumeration can be used to investigate this problem, and exhibit a rewriting using only 14 cubes.

Characterizations for the Riesz potential and its commutators on generalized Orlicz-Morrey spaces
In the present paper, we shall give a characterization for the Spanne and Adams type boundedness of the Riesz potential and its commutators on the generalized Orlicz-Morrey spaces, respectively.

On the structure of certain nontransitive diffeomorphism groups on open manifolds [PDF]
It is shown that in some generic cases the identity component of the group of leaf preserving diffeomorphisms (with not necessarily compact support) on a foliated open manifold is perfect. Next, it is proved that it is also bounded, i.e.

Commutators and Anti-Commutators of Idempotents in Rings
We show that a ring $\,R\,$ has two idempotents $\,e,e'\,$ with an invertible commutator $\,ee'-e'e\,$ if and only if $\,R \cong {\mathbb M}_2(S)\,$ for a ring $\,S\,$ in which $\,1\,$ is a sum of two units. In this case, the "anti-commutator" $\,ee'+e'e\

Weighted Morrey estimates for Hausdorff operator and its commutator on the Heisenberg group [PDF]
In this paper, we study the high-dimensional Hausdorff operators, defined via a general linear mapping $A$, and their commutators on the weighted Morrey spaces in the setting of the Heisenberg group. Particularly, under some assumption on the mapping $A$,
