Peak anaerobic power in master athletes

European Journal of Applied Physiology and Occupational Physiology, 1991
The age-related decline in maximal physical performance of healthy subjects may be attributed both to the aging process per se and/or to a progressive reduction in physical activity. In two groups of master athletes, power (P) or endurance (E) trained (n = 115; aged 40-78 years), the degree and rate of the age-related deterioration of the maximal ...

Peak anaerobic power in elderly men

European Journal of Applied Physiology, 1997
The relationship of maximal anaerobic power (Pmax) of the quadriceps muscle and corresponding optimal shortening velocity (vopt) with age, habitual physical activity (PA) and maximal oxygen consumption (VO2max) were assessed in 37 healthy older [71.1 (SD 3.8) years] men and compared to those of 16 young [22.7 (SD 3.4) years] men.

Methods of Keeping Down Peaks on Power Purchased on a Peak Basis

Transactions of the American Institute of Electrical Engineers, 1914
The author mentions two general ways of reducing peaks, the first being to furnish the peak power from a separate source such as a local steam turbine, and the second to store some of the power furnished by the power company, which is given up later when the peak demand comes on. In the case of the plant described by the author a mixed pressure turbine

Peak Power Minimization through Power Management Scheduling

APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006
As the design complexity continues to increase, huge peak power may lead to logic errors due to voltage drops or reliability problems due to electromigration. A widely used power management technique is to shut down unused operations. However, to enable the power management of an operation, the corresponding control operations must be scheduled before ...

Sequential signalling under a peak power constraint

IEEE Transactions on Information Theory, 1971
The error exponent for sequential signaling over the additive-Gaussian-white-noise channel subject to a peak power constraint is derived. This exponent is maximum under the assumption that information is transmitted in blocks.

High Peak Power Mamyshev oscillators

Optical Fiber Communication Conference (OFC) 2019, 2019
Recent progress in scaling the peak power of femtosecond-pulse fiber oscillators will be reviewed. So-called Mamysehv oscillators achieve peak powers an order of magnitude higher than those of prior fiber lasers.

Peak efficiency and peak power point of wireless power transfer system for electromobility applications

2016 ELEKTRO, 2016
The article deals with the analysis of series — series-compensated circuit for systems of contactless charging of electricity in electromobility applications. The article introduces an analysis of the transfer characteristics of the system depending on change of the distance and of the transmitted power.

Peak Power Control in Multicarrier Communications

2007
Peak signal power is an important factor in the implementation of multicarrier (MC) modulation schemes, like OFDM, in wireless and wireline communication systems. This 2007 book describes tools necessary for analyzing and controlling the peak-to-average power ratio in MC systems, and how these techniques are applied in practical designs.
