Sentence examples for by spectral density using from inspiring English sources

This step was repeated twice, and peptide content was determined by spectral density using UV light at 280 nm.

Then, the epoch was subjected to power spectral density estimation, using Welsh's averaged periodogram method [ 9], and the spectral edge frequency 95% (SEF95) was computed from the power spectral density using a frequency range of 0.5 32 Hz.

This was corroborated by spectral density analysis revealing a marked reduction in ultradian frequencies upon Meth treatment.

Further, the spatial covariance function in Eq. (3) can be expressed as a power spectral density by using a three-dimensional Fourier transform (see Wheelon 2004, p.

For this work, we calculate the width of the power spectral density (Δf) using the following procedure.

It should be noted that this definition of the power spectral density function, used by Ishimaru (1997), differs in (2π)− 3 with that of Sato et al. (2012).

Our contribution in this study is to utilize both the SOM properties and the advantages of spectral clustering, by obtaining the data representatives (prototypes) with the SOM and clustering the SOM prototypes by spectral partitioning using a local density-based similarity CONN instead of a distance-based similarity, for agriculture monitoring.

In the resulting time windows, power spectral density was averaged using fast Fourier transformation.

Power spectral density was calculated using the short-time Fourier transform with a Hamming window of 1 s, without overlap, and was normalized by the total power of the signal up to 300 Hz.

Power spectral density was calculated using short-time Fourier transform with a Hamming window of 1 s and 75% overlap.

The peptide content was estimated by UV light spectral density at 280 nm using an extinction coefficient of 1.1 of 0.1 % (g/l) solution that was calculated on the basis of the frequency of tryptophan and tyrosine in vertebrate proteins [ 20, 21].
