Non-exhaustive tests for critical power estimation
Science & Sports, 2009Objective The aim of this study was to propose a new method that allows for the estimation of critical power (CP) from non-exhaustive tests using ratings of perceived exertion (RPE). Methods Twenty-two subjects underwent two practice trials for ergometer and Borg 15-point scale familiarization, and adaptation to severe exhaustive exercise.

The DTT device: Power and particle exhaust
Fusion Engineering and Design, 2017Abstract The possible scenarios at full power of the DTT (Divertor Test Tokamak) device with the standard single null (SN) and X divertor (XD) configurations have been analysed for the aspect of safely handling the power to be exhausted on the divertor targets.

ELM-averaged power exhaust on JET
Nuclear Fusion, 2005This paper describes experiments performed on JET over the past two years dedicated to characterizing ELM-averaged power exhaust (based on time-averaged divertor power deposition profiles), with an emphasis on unfuelled, Type-I ELMy H-mode. Radial energy transport in the scrape-off layer (SOL) is found to behave differently in the ion and electron ...

Exhaustible-renewable wind power
2017Wind energy is commonly thought as part of renewable energies. “Renewable” points to the idea that wind, being a flow-energy, is not exhaustible. In economic terms, it is thought as non-rival: harnessing the energy of the wind does not deprive others from the possibility of doing so.

Radiative Power Exhaust from ITER
Contributions to Plasma Physics, 1996AbstractRadiative plasma power exhaust from the core, mantle, and SOL/divertor regions has been evaluated for ITER, with emphasis upon establishment of a radiative mantle by impurity seeding in the SOL. The simulations investigated different seeded impurities, compatibility with the H‐mode, and sensitivity to different impurity pinch velocities.

Power and particle exhaust in an ST-FNSF
2013 IEEE 25th Symposium on Fusion Engineering (SOFE), 2013A spherical tokamak (ST) configuration is favorable for a Fusion Nuclear Science Facility (FNSF), due to its small size and relatively low cost. However, the compactness of the ST also exacerbates the power and particle handling problems anticipated in next-step devices, since local fluxes are higher and less space is available for optimizing plasma ...

Physiological responses during exercise to exhaustion at critical power
European Journal of Applied Physiology, 2002Critical power (CP) is a theoretical construct derived from a series of constant load tests to failure. Many studies have examined the methodological limitations of deriving CP, but few studies have examined the responses to exercise at CP in well-trained individuals.

UPQC: An Exhaustive Solution to Improve Power Quality
2020 4th International Conference on Electronics, Communication and Aerospace Technology (ICECA), 2020To improve power quality in the distribution system, various custom power devices like dynamic voltage restorer (DVR), distribution static synchronous compensator (D-STATCOM), and unified power quality conditioner (UPQC) are used. DVR takes care of voltage related problems viz. voltage sag, swell, interruption. D-STATCOM either generates or absorbs the

Exhaust means for pneumatic power tool
The Journal of the Acoustical Society of America, 1991A sound depressing exhaust means for a pneumatic power tool with a substantially cylindrical housing (10) and a vane motor (11) with exhaust port means (23), has an annular casing (41) surrounding a portion of the housing (10), and four expansion chambers (31-32, 34, 36, 39) arranged in series and combined with four flow restrictions (33, 37, 30, 35 ...

Exhaust Port Shapes for Sound and Power
SAE Technical Paper Series, 1973<div class="htmlview paragraph">A theoretical analysis is presented that predicts significant reductions in exhaust pulse amplitudes and hence exhaust noise levels by varying the shape of the exhaust port in a spark-ignited 2-cycle engine. Verification and correlation with experimental results are also presented.</div>
