Meaning of quadratic structure functions
Journal of the Optical Society of America, 1980Quadratic structure functions are sometimes used to describe the phase of partially coherent waves. The physical significance of such structure functions, that they describe a tilted but unwarped phase, limits their applicability to propagation calculations.

Quadratic mean function of entire Dirichlet series
2012Let \(E\) be the set of all entire functions \(f(s)= \sum a_ n e^{s\lambda_ n}\) defined by an everywhere convergent Dirichlet series, where \[ \limsup_{n\to+\infty} {\log n\over \lambda_ n}= D\in \mathbb{R}_ +\cup \{0\}. \] Let \[ I_ 2(\sigma,f)= \lim_{T\to+\infty} {1\over 2T} \int^ T_{-T} | f(\sigma+ it)|^ 2 dt.

MEAN–VARIANCE PORTFOLIO CHOICE: QUADRATIC PARTIAL HEDGING
Mathematical Finance, 2005In this paper we investigate the problem of mean–variance portfolio choice with bankruptcy prohibition. For incomplete markets with continuous assets' price processes and for complete markets, it is shown that the mean–variance efficient portfolios can be expressed as the optimal strategies of partial hedging for quadratic loss function.

Measurement of quadratic mean deviations by means of a cathode-ray tube
Measurement Techniques, 1962The above method can be applied not only to processes with a normal distribution law. If the signal amplitudes are distributed according to an equal probability law, which is apparent from the glowing of the screen, the quadratic mean deviation in this instance can be determined from the width Δ of the uniformly glowing strip on the screen by ...
