Abstract. Detailed simulation of wind generation as driven by weather patterns is required to quantify the impact on electrical grid power fluctuations in offshore fleets. This paper focuses studying high-installation-density fleets since they present a growing challenge operation and planning systems Europe. The Belgian fleet studied because it has highest density installation Europe 2020, new...

Primordial fluctuations in the cosmic density are usually assumed to take the form of a Gaussian random field that evolves under the action of gravitational instability. In the early stages, while they have low amplitude, the fluctuations grow linearly. During this phase the Gaussian character of the fluctuations is preserved. Later on, when the fluctuations have amplitude of order the mean den...

Luminosity monitors were used to study density fluctuations in the cold helium-4 target of the HAPPEX-He parity violation experiment in Jefferson Lab Hall A. Helicity-correlated asymmetries were measured as beam current, beam raster size, target fan speed, and target density were varied. These studies were used to determine optimal running conditions and estimate the contribution of target dens...
