Nonparametric density estimation using a multidimensional mixture model of Gaussian distributions
Lietuvos Matematikos Rinkinys, 2005 This paper algorithmically and empirically studies five major types of nonparametric multivariate density estimation techniques, where no assumption is made about data being drawn from any of known parametric families of distribution. There is developed

Geometry of conformal manifolds and the inversion formula
Journal of High Energy Physics, 2023 Families of conformal field theories are naturally endowed with a Riemannian geometry which is locally encoded by correlation functions of exactly marginal operators.

A Unified Depletion/Inversion Model for Heterojunction Trigate FinFETs DC Characteristics
IEEE Access, 2021 This paper presents a comprehensive $I-V$ model for the evaluation of above threshold DC characteristics of trigate AlGaN/GaN FinFETs for both depletion and inversion mode of operations. For the depletion mode, 2DEG carrier concentration, $n_{s}$ , is

A double inversion formula [PDF]
Pacific Journal of Mathematics, 1980 Let \(G\) be an abelian group and \(\{a_n\}\) and \(\{b_n\}\), \(n\ge 1\), be sequences in \(G\). Let \(p\) be an odd prime and \(\eta_e = \left(\frac{e_1}{p}\right)\), the Legendre symbol, where \(e = p^s e_1\), \(s\ge 0\), \(p\nmid e_1\). Set \(\chi_e^{\pm} = (1 \pm \eta_e)/2\). Define the sequence \(\{c_n\}\) and \(\{d_n\}\), \(n\ge 1\), by \[ c_n =

Integral geometry on discrete matrices
Moroccan Journal of Pure and Applied Analysis, 2021 In this note, we study the Radon transform and its dual on the discrete matrices by defining hyperplanes as being infinite sets of solutions of linear Diophantine equations. We then give an inversion formula and a support theorem.

Sensors, 2021 Horizontal-to-Vertical Spectral Ratios (HVSR) and Rayleigh group velocity dispersion curves (DC) can be used to estimate the shallow S-wave velocity (VS) structure. Knowing the VS structure is important for geophysical data interpretation either in order

Inversion of Gamow’s formula and inverse scattering
American Journal of Physics, 2006 Gamow’s tunneling formula is inverted and the issue of the uniqueness of the solution is compared with the solution obtained by the method of Gel’fand and Levitan. Some insight is gained into the key differences between classical and quantum inverse scattering, which account for the fact that a potential can be uniquely determined in the latter but ...

Complimentary information using in the task of averaging operators inversion in function space [PDF]
Компьютерные исследования и моделирование, 2011 The dual task of integral geometry - to define for a given averaging operator the function class where inversion of that operator is possible - is solved. Those classes are defined ambiguously.
