Reference crop evapotranspiration or reference evapotranspiration, denoted as ETo or ETref, is the estimation of the evapotranspiration from the "reference surface. "The reference surface is a hypothetical grass reference crop with an assumed crop height of 0. 12 m, a fixed surface resistance of 70 s/m and an albedo of 0. 23. The reference surface closely resembles an extensive surface of green, well-watered grass of uniform height, actively growing and completely shading the ground. The fixed surface resistance of 70 s/m implies a moderately dry soil surface resulting from about a weekly irrigation frequency.  1, record 1, English, - reference%20evapotranspiration

The data is then analyzed by a spectrum estimation algorithm to obtain the most accurate representation of the acquired signal into frequency bands. To achieve real-time spectrum-sensing implementations, the algorithm needs to have low computational costs and be able to detect the small, quiet periods defined in various standards.  2, record 2, English, - spectrum%20estimation%20algorithm

New methods of acoustic imaging are presented that provide images with reduced reverberation noise and images of nonlinear scattering and propagation parameters of the object, and estimation methods of corrections for wave front aberrations produced by spatial variations in the acoustic propagation velocity. The methods find use in a variety of applications such as acoustic imaging of geological structures, SONAR imaging of sub-sea objects, and medical ultrasound imaging. The methods are based on processing of the received signal from transmitted dual frequency band acoustic pulse complexes with overlapping high and low frequency pulses. The high frequency pulse is used for the image reconstruction and the low frequency pulse is used to manipulate the nonlinear scattering and/or propagation properties of the high frequency pulse.  3, record 3, English, - acoustic%20imaging

A cepstrum is a spectrum of a logarithmic power spectrum. Because of this, a peak in the cepstrum indicates periodicity in the spectrum; usually, this signifies a family of harmonics at equal frequency intervals.  1, record 4, English, - cepstral%20analysis

Cepstral analysis has been widely applied to gear monitoring. The cepstrum is well suited for the detection of sidebands in vibration spectra and for the estimation of their evolution during gear life. In addition, since the cepstrum estimates the average sideband spacing over a wide frequency range, it allows very accurate measurement of the sideband periodicity. It is therefore applicable to both detection and diagnosis of gear faults.  2, record 4, English, - cepstral%20analysis
