Line asymmetry of solar p-modes: Reversal of asymmetry in intensity power spectra [PDF]

open access: yes, 1999
The sense of line asymmetry of solar p-modes in the intensity power spectra is observed to be opposite of that seen in the velocity power spectra. Theoretical calculations provide a good understanding and fit to the observed velocity power spectra ...

Concurrent validity of Myotest for assessing explosive strength indicators in countermovement jump

open access: yesActa Gymnica, 2018
Background: Previous research has determined the validity and reliability of accelerometer-based devices, but the findings are not consistent. Objective: The purpose of this study was to determine the validity of an accelerometer (Myotest PRO) for ...

Inertial Energy Storage for Spacecraft [PDF]

open access: yes, 1984
The feasibility of inertial energy storage in a spacecraft power system is evaluated on the basis of a conceptual integrated design that encompasses a composite rotor, magnetic suspension and a permanent magnet (PM) motor/generator for a 3-kW orbital ...

Peak-to-average power ratio of good codes for Gaussian channel [PDF]

open access: yes, 2014
Consider a problem of forward error-correction for the additive white Gaussian noise (AWGN) channel. For finite blocklength codes the backoff from the channel capacity is inversely proportional to the square root of the blocklength.

Effects of different rest intervals in high intensity interval training programs on VO2max, body composition, and isokinetic strength and power [PDF]

open access: yesJournal of Men's Health
The aim of this study was to evaluate the effect of 8 weeks of short and long rest running-based high-intensity training (HIIT) on body composition, isokinetic strength, and maximal oxygen uptake (VO2max). Nineteen physically active men were recruited

Peak-power-point monitor for solar panel [PDF]

open access: yes, 1972
Attempt was made to determine solar cell panel peak power capability without disrupting power flow from panel. Separate solar cell strings were switched from panel circuits, and increasingly larger loads were added rapidly until peak power points were ...

Capacity and Modulations with Peak Power Constraint [PDF]

open access: yes, 2011
A practical communication channel often suffers from constraints on input other than the average power, such as the peak power constraint. In order to compare achievable rates with different constellations as well as the channel capacity under such ...

Polynomial Curve Slope Compensation for Peak-Current-Mode-Controlled Power Converters [PDF]

open access: yes, 2019
Linear ramp slope compensation (LRC) and quadratic slope compensation (QSC) are commonly implemented in peak-current-mode-controlled dc-dc converters in order to minimize subharmonic and chaotic oscillations.
