DITKIN CONDITIONS

open access: yesGlasgow Mathematical Journal, 2017
AbstractThis paper is about the connection between certain Banach-algebraic properties of a commutative Banach algebra E with unit and the associated commutative Banach algebra C(X, E) of all continuous functions from a compact Hausdorff space X into E. The properties concern Ditkin's condition and bounded relative units.

Enhancement of reliability in condition monitoring techniques in wind turbines [PDF]

open access: yes, 2019
The majority of electrical failures in wind turbines occur in the semiconductor components (IGBTs) of converters. To increase reliability and decrease the maintenance costs associated with this component, several health-monitoring methods have been ...

Coastal conditions [PDF]

open access: yesArchitectural Research Quarterly, 2011
Houses are fascinating because they seem to occupy a pivotal position in the spectrum of human construction. They are, perhaps, located right on the watershed between what is generally understood as ‘architecture’ and what is considered as just ‘building’. They allow us to probe the very definition of what architecture is perceived to be.

Optimizing condition numbers [PDF]

open access: yes, 2009
In this paper we study the problem of minimizing condition numbers over a compact convex subset of the cone of symmetric positive semidefinite $n\times n$ matrices. We show that the condition number is a Clarke regular strongly pseudoconvex function.
