Wind Turbine Condition Monitoring: State-of-the-Art Review, New Trends, and Future Challenges
, 2014 As the demand for wind energy continues to grow at exponential rates, reducing operation and maintenance (OM) costs and improving reliability have become top priorities in wind turbine (WT) maintenance strategies.

Finiteness Conditions for a Group of Finite Exponent
Journal of Algebra, 1993 A periodic group \(G\) all of whose \(d\)-generator subgroups (for fixed \(d > 1\)) are solvable need not itself be solvable (Golod), and similarly for nilpotence. However if \(G\) is finite, then the solvability of every 2- generator subgroup entails the solvability of \(G\) (Thompson), and likewise for nilpotence.

, 2012 We prove that every heteroclinic saddle loop (a two-saddle cycle) occurring in an analytic finite-parameter family of plane analytic vector fields, may generate no more than a finite number of limit cycles within the family.Comment: 21 pages, 10 figures,

A finiteness condition for finitely generated semigroups
Semigroup Forum, 1989 Let S be a finitely generated semigroup all of whose subgroups are locally finite. It is shown that, if for every \(s\in S\) there exists \(n\geq 2\) such that \(s=s^ n\) (that is S is a union of locally finite groups), then S is finite. This extends a result of \textit{A. de Luca} and \textit{A.
