The role of geoinformatics techniques in predicting the urban growth of the city of Suez, Egypt, using the frequency ratio model. [PDF]
The International Journal of Informatics, Media and Communication Technology, 2023 Geoinformatics techniques help solve the most important real problems facing the city of Suez, perhaps the most prominent of which is the problem of population increase and the pressure on the current urban area.

Estimating Diversity via Frequency Ratios [PDF]
Biometrics, 2015 SummaryWe wish to estimate the total number of classes in a population based on sample counts, especially in the presence of high latent diversity. Drawing on probability theory that characterizes distributions on the integers by ratios of consecutive probabilities, we construct a nonlinear regression model for the ratios of consecutive frequency ...

Ultraprecise Measurement of Optical Frequency Ratios [PDF]
Physical Review Letters, 2002 We developed a novel technique for frequency measurement and synthesis, based on the operation of a femtosecond comb generator as transfer oscillator. The technique can be used to measure frequency ratios of any optical signals throughout the visible and near-infrared part of the spectrum. Relative uncertainties of $10^{-18}$ for averaging times of 100

Discrimination of frequency ratios [PDF]
The Journal of the Acoustical Society of America, 1986 Recent work on spectral profile analysis demonstrates that observers can extract amplitude relationships between components in complex stimuli. The experiments to be discussed demonstrate that observers also can extract frequency relationships, specifically, they can discriminate frequency ratios of components in a two-tone complex.

Ratcheting occurrence conditions of piping under sinusoidal excitations
Mechanical Engineering Journal, 2020 Ratcheting is one of the dominant failure modes under excessive earthquakes and may cause extreme failures of structures (e.g., collapse). We focused on clarifying the ratcheting mechanism of piping under sinusoidal excitations.
