Birkhoff-James approximate orthogonality sets and numerical ranges [PDF]
In this paper, the notion of Birkhoff–James approximate orthogonality sets is introduced for rectangular matrices and matrix polynomials. The proposed definition yields a natural generalization of standard numerical range and q-numerical range (and also ...

Dimensional Lifting through the Generalized Gram–Schmidt Process
A new way of orthogonalizing ensembles of vectors by “lifting” them to higher dimensions is introduced. This method can potentially be utilized for solving quantum decision and computing problems.

Numerical Study on the Orthogonality of the Fields Radiated by an Aperture
This work studies the orthogonality of the fields radiated by the different modes of a radiating aperture. Waveguide modes exhibit an orthogonality property at the aperture cross-section that can be used to simplify calculations.
