Vibrations of defective gearboxes show great complexities. Therefore, dynamics and noise levels of vibrations of gearboxes vary with operation of gearboxes. As a result, nonlinearity and determinism of data can serve to describe running conditions of gear... see more

En este trabajo se muestra la tendencia de escala de las fluctuaciones de registros de concentración contaminante del aire tomados de la estación de monitoreo Merced (MER) de la zona metropolitana del valle de México (ZMVM). La función de estructura de or... see more

Turbulent atmosphere produces random wavefront tilt in the propagating laser beam and the dynamics of turbulence is largely depend on the receiving optics aperture size. In this paper, wavefront tilt variance is studied with various telescope aperture siz... see more

The features of Hurst exponent H of the classical Brownian motion trajectory calculated by the R/S-analysis has been studied, where R is a range of a cumulative deviations of the chosen fragment of the trajectory within the time interval  (from the m... see more

Nonlinear time series analysis of data related to the radioactivity profile of a hot spring area can explore the dynamics of the geothermal activities along with other different nonlinear features of the Earth system. However, not much work in this field ... see more

El mercado bursátil constituye un sistema social, dinámico y complejo. Por tanto, para caracterizarlo y modelarlo es necesario contar con herramientas que nos permitan estudiar de qué manera se producen las diferentes interrelaciones entre los elementos d... see more

The development of methods describing time series using stochastic processes took place in the 20th century. Among others, stationary processes were modelled with Hurst exponent, whereas non-stationary processes with Hölder function. The characteristic fe... see more

A fractal analysis from rainfall events registered in a semiarid region was carried out. The analysis was executed for Baja California, Mexico, a region that presents a high climatological variability. Rainfall data from 92 climate stations distributed al... see more
