Some new hybrid power mean formulae of trigonometric sums

open access: yesAdvances in Difference Equations, 2020
We apply the analytic method and the properties of the classical Gauss sums to study the computational problem of a certain hybrid power mean of the trigonometric sums and to prove several new mean value formulae for them.

One Kind New Hybrid Power Mean and Its Computational Formulae

open access: yesJournal of Mathematics, 2022
The main purpose of this study is to use the elementary and analytic methods and the properties of the classical Gauss sums to study the calculation problems of one kind of hybrid power mean involving the quadratic character sums and the two-term ...

Steps toward the power spectrum of matter. I.The mean spectrum of galaxies

open access: yes, 1998
We calculate the mean power spectrum of galaxies using published power spectra of galaxies and clusters of galaxies. On small scales we use the power spectrum derived from the 2-dimensional distribution of APM galaxies, on large scales we use power ...

On the Peak-to-Mean Envelope Power Ratio of Phase-Shifted Binary Codes [PDF]

open access: yes, 2007
The peak-to-mean envelope power ratio (PMEPR) of a code employed in orthogonal frequency-division multiplexing (OFDM) systems can be reduced by permuting its coordinates and by rotating each coordinate by a fixed phase shift.

Scattering a pulse from a chaotic cavity: Transitioning from algebraic to exponential decay

open access: yes, 2008
The ensemble averaged power scattered in and out of lossless chaotic cavities decays as a power law in time for large times. In the case of a pulse with a finite duration, the power scattered from a single realization of a cavity closely tracks the power

Exact inequalities involving power mean, arithmetic mean and identric mean

open access: yesJournal of Numerical Analysis and Approximation Theory, 2011
For \(p\in \mathbb{R}\), the power mean \(M_{p}(a,b)\) of order \(p\), identric mean \(I(a,b)\) and arithmetic mean \(A(a,b)\) of two positive real numbers \(a\) and \(b\) are defined by \begin{equation*} M_{p}(a,b)= \begin{cases} \displaystyle\left(

Wingate normative-reference values for a large cohort of Canadian university students

open access: yesBiomedical Human Kinetics
Study aim: The Wingate Anaerobic Test evaluates anaerobic power and capacity. Used to assess performance, historically among athletic populations, its evaluative capacity for individuals of varying athletic abilities is limited by a lack of normative ...
