Discriminant analysis of concentrations of trace elements in Ulaanbaatar soil

Proceedings of the Mongolian Academy of Sciences
In this work we investigated, through discriminant analysis, the spatial variability and pollution sources of potential toxic elements in Ulaanbaatar surface soil.

A Polynomial Spectral Calculus for Analysis of DG Spectral Element Methods

, 2017
We introduce a polynomial spectral calculus that follows from the summation by parts property of the Legendre-Gauss-Lobatto quadrature. We use the calculus to simplify the analysis of two multidimensional discontinuous Galerkin spectral element ...

Spectral analysis of the free orthogonal matrix [PDF]

, 2009
We compute the spectral measure of the standard generators $u_{ij}$ of the Wang algebra $A_o(n)$. We show in particular that this measure has support $[-2/\sqrt{n+2},2/\sqrt{n+2}]$, and that it has no atoms.

Spectral Analysis of the Stromlo-APM Survey I. Spectral Properties of Galaxies

, 1999
We analyze spectral properties of 1671 galaxies from the Stromlo-APM survey, selected to have 15 < b_J < 17.15 and having a mean redshift z = 0.05. This is a representative local sample of field galaxies, so the global properties of the galaxy population

Knowledge Transfer Between Artificial Intelligence Systems

Frontiers in Neurorobotics, 2018
We consider the fundamental question: how a legacy “student” Artificial Intelligent (AI) system could learn from a legacy “teacher” AI system or a human expert without re-training and, most importantly, without requiring significant computational ...

Wavelet analysis as a p-adic spectral analysis

, 2001
New orthonormal basis of eigenfunctions for the Vladimirov operator of p-adic fractional derivation is constructed. The map of p-adic numbers onto real numbers (p-adic change of variables) is considered. This map (for p=2) provides an equivalence between
