Fourier transform emission spectroscopy can make an important contribution in the observation of the Earth's atmosphere and in the investigation of atmospheric physics and chemistry. In this paper, we...
Discriminant analysis of Olomouc curd cheese by Fourier transform near infrared spectroscopy
ripening Mahalanobis distance
2014/3/28
We used the discriminant analysis of curd cheese during storage by Fourier transform near infrared spectroscopy method (FT-NIRs). Olomouc curd cheese samples were stored at 5 and at 20°C during seven ...

Homogenization Fast Fourier Transform Conjugate Gradients
2011/8/18
Abstract: The focus of this paper is on the analysis of the Conjugate Gradient method applied to a non-symmetric system of linear equations, arising from a Fast Fourier Transform-based homogenization ...
Fourier transform based iterative method for x-ray differential phase-contrast computed tomography
X-ray phase-contrast tomography, x-ray refractive index, iterative reconstruction,interior tomography
2011/9/6
Biological soft tissues encountered in clinical and pre-clinical imaging mainly consist of light element atoms, and their composition is nearly uniform with little density variation. Thus,x-ray attenu...
Lagrange-mesh calculations and Fourier transform
Lagrange-mesh calculations Fourier transform
2011/9/1
The Lagrange-mesh method is a very accurate procedure to compute eigenvalues and eigenfunctions of a two-body quantum equation. The method requires only the evaluation of the potential at some mesh po...
The su(2)_α Hahn oscillator and a discrete Hahn-Fourier transform
su(2)_α Hahn oscillator discrete Hahn-Fourier High Energy Physics
2011/7/25
Abstract: We define the quadratic algebra su(2)_{\alpha} which is a one-parameter deformation of the Lie algebra su(2) extended by a parity operator. The odd-dimensional representations of su(2) (with...
