  • Interesting fact: In 1978, the World Water Speed record was made by Ken Warby from Australia. His average speed was 317.6 mph, and his jet-powered hydroplane was 27 feet long called "Spirit of Australia." Warby built the boat himself in his back yard
    • powered Having power (of a specified kind or degree): used especially in composition: as, high-powered or low-powered rifles or guns. The measure of a gun's power is its muzzle-velocity, or the velocity with which the projectile leaves the muzzle. This in modern guns is about 2,000 feet per second, but there is no exact dividing-line between guns of high power and those of low power.

In science:

The value of this power depends essentially on the assumptions underlying the data analysis: a single power law or a power law behaviour with a subdominant correction.
The 3-d Random Field Ising Model at zero temperature
An important property of the SF is that the SF of a time series whose Fourier power spectrum follows a power-law also follows a power-law.
Very rapid optical variability of PKS 2155-304
Power Spectra In the ACDM model the primeval mass density fluctuation (defined as the most rapidly growing density perturbation mode in time-orthogonal coordinates) has a close to power law power spectrum, P ∝ kn .
Issues for the Next Generation of Galaxy Surveys
Each experiment quotes one (or in the best cases several) measures of power over a range of multipoles, and these can be quoted as ‘band powers’ or equivalent amplitudes of a flat power spectrum through some ‘window function’.
New physics from the Cosmic Microwave Background
The bound is obviously in conflict with a fixed power behaviour, so the power s0.08 can only be an effective power, which must reduce as s increases.
Pomeron physics: an update
The two power spectra differ increasingly with scale at k > 500 Mpc−1 , but the Peacock and Dodds (1996) power spectrum is not reliable there due to the resolution limit of the simulations from which the non-linear power spectrum was derived.
Applications of Halo Approach to Non-Linear Large Scale Structure Clustering
We also refer the reader to Seljak 2000 for a discussion of the detailed properties of galaxy power spectra due to halos; we briefly discuss the sub ject of galaxy power spectra in § 1.7 using the PCSZ redshift-space galaxy power spectrum from Hamilton & Tegmark (2000).
Applications of Halo Approach to Non-Linear Large Scale Structure Clustering
Since the lensing power spectrum is simply a pro jected measure of the dark matter power spectrum, the variations in the weak lensing angular power spectra are consistent with the behavior observed in the dark matter power spectrum.

Applications of Halo Approach to Non-Linear Large Scale Structure Clustering
The power spectra here represent the baryon field power spectrum and the velocity field power spectrum; the former assumed to trace the dark matter density field while the latter is generally related to the linear dark matter density field through the use of linear theory arguments.
Applications of Halo Approach to Non-Linear Large Scale Structure Clustering
Under the halo model, a halo power spectrum equal to the nonlinear mass power spectrum is the extreme limit since there would then be no room for intrahalo power associated with their profiles.
Applications of Halo Approach to Non-Linear Large Scale Structure Clustering
For example in a PC, the processors on a motherboard all have the same type, the ram units have the same wait times, the total power of a power supply must exceed the total power demand of all the devices.
Pruning Isomorphic Structural Sub-problems in Configuration
Thus, if the large scales have too little power intrinsically (i.e., if n > 4 ), then the long wavelength power will soon be dominated by the “k4 - tail” of the short wavelength power arising from the nonlinear clustering.
Gravitational clustering in Static and Expanding Backgrounds
Both the synchrotron and high energy peak are similar in power output, unlike the EGRET-detected flat spectrum radio sources which can have their “Compton” power peaks well above the synchrotron power peaks.
