Illumination of Orthogonal Polygons with Orthogonal Floodlights

International Journal of Computational Geometry & Applications, 1998
We provide the first tight bound for covering an orthogonal polygon with n vertices and h holes with vertex floodlights (guards with restricted angle of vision). In particular, we provide tight bounds for the number of orthogonal floodlights, placed at vertices or on the boundary, sufficient to illuminate the interior or the exterior of an orthogonal ...

Atrial Fibrillation Prediction With Residual Network Using Sensitivity and Orthogonality Constraints

IEEE journal of biomedical and health informatics, 2019
Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia. The atrial beat is irregular during AF, which causes blood flow hardly. This may cause blood clot formation and cardioembolic strokes.

On orthogonal polynomials

Analysis Mathematica, 1975
Пустьw(х)∈L[-1, +1] — неотрица тельная функция така я, что $$\frac{{\log ^ + \frac{1}{{w(x)}}}}{{\sqrt {1 - x^2 } }} \in L[ - 1, + 1]$$ и пусть {(рn(х)} — много члены, ортогональные и нормированные с весо мw(x). Мы доказываем следующие две теорем ы, являющиеся обобщен ием одного известного результа та Н. Винера. I.

Orthogonal and non-orthogonal hybrids

Journal of Molecular Structure: THEOCHEM, 1988
Abstract Ab initio MO wave functions for XHn molecules are analyzed in terms of the hybridization concept. It was found that for X from the first row (especially for carbon) the hybrid-AOs so obtained are close to orthogonal. If X is from the second row, different hybrids on the same atom overlap strongly and the well-known relations between degree ...

A complete characterization of Birkhoff-James orthogonality in infinite dimensional normed space

, 2017
In this paper, we study Birkhoff-James orthogonality of bounded linear operators and give a complete characterization of Birkhoff-James orthogonality of bounded linear operators on infinite dimensional real normed linear spaces.

Algebraic orthogonality and commuting projections in operator algebras

, 2017
We provide an order-theoretic characterization of algebraic orthogonality among positive elements of a general C*-algebra by proving a statement conjectured in [12].

Orthogonalization Methods

Journal of Mathematical Physics, 1970
An essentially unique method of forming an orthonormalized set of vectors from an independent set of n vectors is presented. The resulting set is proven to maximize a certain quartic form in the original vectors.

Univocal or Orthogonal Estimators of Orthogonal Factors

Psychometrika, 1963
The defects of the least-squares or multiple-regression equation approach to estimating orthogonal factors are discussed and transformations of the beta weights are derived which remove these defects with minimum loss in correlations between estimators and true factor scores.
