Correlations between political party size and voter memory: A statistical analysis of opinion polls
Christian A. Andresen, Henning F. Hansen, Alex Hansen +2
This paper describes the application of statistical methods to political polling data in order to look for correlations and memory effects. We propose measures for quantifying the…
Optimized suppression of coherent noise from seismic data using the Karhunen-Loeve transform
Raul Montagne, Giovani L. Vasconcelos
Signals obtained in land seismic surveys are usually contaminated with coherent noise, among which the ground roll (Rayleigh surface waves) is of major concern for it can severely…
Scaling relations for diversity of languages
M. A. F. Gomes, G. L. Vasconcelos, I. J. Tsang +1
The distribution of living languages is investigated and scaling relations are found for the diversity of languages as a function of the country area and population. These results…
Complex dynamics in a one--block model for earthquakes
Raul Montagne, G. L. Vasconcelos
A two-dimensional earthquake model that consists of a single block resting upon a slowly moving rough surface and connected by two springs to rigid supports is studied. Depending o…
Single-particle model for a granular ratchet
A. J. Bae, W. A. M. Morgado, J. J. P. Veerman +1
A simple model for a granular ratchet corresponding to a single grain bouncing off a vertically vibrating sawtooth-like base is studied. Depending on the vibration strength, the sa…
