Background: The priniciple objective here is to analyze cardiovascular dynamics in diabetic subjects by actions related to heart rate variability (HRV). The correlation of chaotic globals is vital to evaluate the probability ...

Scaling relationships (where body size features as the independent variable) and power-law distributions are commonly reported in ecological systems. In this review we analyze scaling relationships related to energy ...

Wind profiles measured with the Arecibo Observatory 430 MHz radar during 1979 and 1980 have been used to calculate frequency and radial wavenumber power spectra. Periods between 2 min and 6 h and vertical wavelengths between ...

Assessing the wave energy resource in zones without spectral data leads to assumptions based on theory to estimate wave parameters such as the energy period. The energy period has been regularly approximated using a ...

This paper presents a study of power quality in the electrical system of a food industry, focusing on detecting harmonics generated by nonlinear loads present in installation. Data collection was done using an electrical ...

There are two kinds of fast activity in the ERG: fast retinal potentials (FRP), an irregular series of spiky wavelets and oscillatory potentials (OP), a rhythmic sequence of events. Corneal ERG from nine intact young carps, ...
