MONITORING NOISE LEVELS ALONG THE GREATER CAIRO URBAN REGION RING ROAD IN EGYPT

Journal of Environmental Science, 2020
In this study, the noise levels were monitored at Cornish EL Maadi (A), Gezirat El Dahab (B) and Al-Marioteya (C). The data revealed that the noise levels at Corniche El Maadi Street (A) and Al-Marioteya (C) (all day) as well as at Gezirat El Dahab (B) (evening) exceeded the set noise regulations in Egypt.

Measuring the broadband power spectra of active galactic nuclei with RXTE [PDF]

, 2002
We have developed a Monte Carlo technique to test models for the true power spectra of intermittently sampled lightcurves against the noisy, observed power spectra, and produce a reliable estimate of the goodness of fit of the given model.
