Most cosmologists don't dispute the primordial nature of the fluctuations seen by COBE and other large-angle experiments.
To examine the smaller angularscale variations associated with the evolution of galaxy superclusters, clusters, or individual galaxies, researchers turn to larger antennas, which can resolve fluctuations on a liner spatial scale.
Temperature fluctuations recorded on the COBE and balloon maps are so faint that the charted hot and cold spots which vary a mere 30 millionths of a kelvin from the background -- represent only average variations over a large scale rather than particular hot and cold regions of the sky, Cheng explains.
By using the more predictable component, which displays less extreme fluctuations than even the vacuum, researchers can substantially improve the sensitivity of their measurements (SN: 3/10/90, p.
But because the plants still fall within the same long time-scale eddy, the power they produce will have correlated fluctuations at low frequencies, which generate the most power.
Fluctuations of the magnetic field will be monitored by a set of 16 optically-pumped alkali-vapor magnetometers (OPM), using the property that the oscillation frequency of an OPM is proportional to the modulus of the local magnetic field.
Much of the research on Holocene glacier and climate fluctuations in western Canada has been done in the southern Canadian Rocky Mountains (see Luckman, 2000, for references).
Large fluctuations in the solar wind affect our local space weather, predicting these is as challenging as predicting large changes in stock prices.
This results in a higher conveying efficiency and a significant reduction of pressure fluctuations.
Real-time measurements on the spatial and temporal fluctuations of single molecules in living cells, which are not possible using other methods, are a major goal of this initiative.

At the same time, strong fluctuations occurred in the power-distribution grid in southern Sweden, damaging capacitors and power cables.
