Calculation of signal spectrum by means of stochastic inversion [PDF]

open access: yesAnnales Geophysicae, 2010
The standard method of calculating the spectrum of a digital signal is based on the Fourier transform, which gives the amplitude and phase spectra at a set of equidistant frequencies from signal samples taken at equal intervals.

Estimation of Error Variance-Covariance Parameters Using Multivariate Geographically Weighted Regression Model

open access: yesAbstract and Applied Analysis, 2020
The Multivariate Geographically Weighted Regression (MGWR) model is a development of the Geographically Weighted Regression (GWR) model that takes into account spatial heterogeneity and autocorrelation error factors that are localized at each observation

On Multivariate Quasipolynomials of the Minimal Deviation from Zero [PDF]

open access: yes, 2001
We generalize to several variables both the upper and the lower Gelfond bounds for the least uniform deviation from zero of the quasipolynomials (or Müntz–Legendre polynomials) on the segment [0, 1].

Long-term taxonomic and functional stability of the gut microbiome from human fecal samples

open access: yesScientific Reports, 2023
Appropriate storage of fecal samples is a critical step for unbiased analysis in human microbiome studies. The purpose of this study was to evaluate the stability of the fecal microbial community for up to 18 months. Ten healthy volunteers provided fecal

Effect of Mixing Condition on Rheological Behavior of Epoxy-Clay Nanocomposites [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2012
The effect of mixing on rheological behavior of 6% wt epoxy-clay nanocomposites was studied. The mixing processes were carried out by low shear mixer, homogenizer and ultrasonic and combination of different mixing techniques at medium and maximum power ...

Accuracy of maturity prediction equations in individual elite male football players

open access: yesAnnals of Human Biology, 2020
Background Equations predicting age at peak height velocity (APHV) are often used to assess somatic maturity and to adjust training load accordingly. However, information on the intra-individual accuracy of APHV in youth athletes is not available.
