Asymptotic distributions and subsampling in spectral analysis for almost periodically correlated time series
α-mixing properties almost periodically correlated time series consistency spectral analysis subsampling
2011/3/21
The aim of this article is to establish asymptotic distributions and consistency of subsampling for spectral density and for magnitude of coherence for non-stationary, almost periodically correlated t...
A Spectral Analysis of Business Cycle Patterns in UK Sectoral Output
business cycle patterns frequency domain
2010/3/9
This paper studies business cycle patterns in UK sectoral output. It analyzes the distinction between white noise processes and their non-white noise counterparts in the frequency domain and further e...
'GAB' generalised equation as a basis for sorption spectral analysis
sorption isotherm GAB food approximation polynomial water activity spectrum
2014/2/27
The transformed sorption isotherm (represented by the ratio of water activity and moisture content (d.b.) versus water activity) was approximated by polynomials of 2nd–6th order. It is shown that the ...

Separating populations with wide data: A spectral analysis
mixture of product distributions clustering small sample spectral analysis
2009/9/16
In this paper, we consider the problem of partitioning a small data sample drawn from a mixture of $k$ product distributions. We are interested in the case that individual features are of low average ...
Spectral Analysis of Reflected Soft X-ray for Detecting Foreign Materials in Foods
soft X-ray spectra transmittance reflectance
2009/6/17
A continuous soft X-ray system with a semi-conductor detector was used to detect foreign materials in food samples. Basic properties of transmitted and reflected soft X-ray for some metallic and non-m...
