Gaussian Bases

open access: yesApplied and Computational Harmonic Analysis, 1995
Consider the functions \(\exp (-\zeta x^2)p_j(x)\) with \(p_j(x)= \sin [\pi/2 (x+1) (j+1/2)]\) and \(\text{Re} \zeta>0\). It is shown in this note that the family \(h_{j,k} (x)=h_j(x-2k)\), \(j=0,1, \dots, k\in Z\) is an unconditional basis for \(L^2(R)\). Also the dual basis for this is constructed. When \(\zeta>0\), this result is implicit in \textit{

Gaussian elimination [PDF]

open access: yesWIREs Computational Statistics, 2011
AbstractAs the standard method for solving systems of linear equations, Gaussian elimination (GE) is one of the most important and ubiquitous numerical algorithms. However, its successful use relies on understanding its numerical stability properties and how to organize its computations for efficient execution on modern computers.

Pauli Gaussian Fibonacci and Pauli Gaussian Lucas Quaternions

open access: yesMathematics, 2022
We have investigated new Pauli Fibonacci and Pauli Lucas quaternions by taking the components of these quaternions as Gaussian Fibonacci and Gaussian Lucas numbers, respectively. We have calculated some basic identities for these quaternions.

Conformations of Steroid Hormones: Infrared and Vibrational Circular Dichroism Spectroscopy

open access: yesMolecules, 2023
Steroid hormone molecules may exhibit very different functionalities based on the associated functional groups and their 3D arrangements in space, i.e., absolute configurations and conformations.

Analyses and Modeling Impulse Noise Generated by Household Appliances

open access: yesAdvances in Electrical and Electronic Engineering, 2014
This paper describes analysis of impulse noise generated by small household appliances. Furthermore we propose a new model of impulse noise based on the averaged power spectrum and the random phase generation with various phase distributions.

Kurtosis in Large-Scale Structure as a Constraint on Non-Gaussian Initial Conditions [PDF]

open access: yes, 1995
We calculate the kurtosis of a large-scale density field which has undergone weakly non-linear gravitational evolution from arbitrary non-Gaussian initial conditions.

Characterizing the performance of continuous-variable Gaussian quantum gates [PDF]

open access: yes, 2020
The required set of operations for universal continuous-variable quantum computation can be divided into two primary categories: Gaussian and non-Gaussian operations.

Mach-Zehnder Interferometer Sensor Curvature Demodulation Method Based on the Orthogonal Decomposition of Spectral Curves

open access: yesIEEE Access, 2020
This paper proposes a curvature demodulation of Mach-Zehnder interferometer (MZI) sensors based on complete spectral information. An MZI sensor composed of two waist-enlarged single mode fibers (SMFs) was fabricated.

Primordial non-Gaussianity and non-Gaussian covariance

open access: yesPhysical Review D, 2023
In the pursuit of primordial non-Gaussianities, we hope to access smaller scales across larger comoving volumes. At low redshift, the search for primordial non-Gaussianities is hindered by gravitational collapse, to which we often associate a scale $k_{\rm NL}$.

On the Dispersion of Gases Discharged to the Chimney of a Thermal Power Plant

open access: yesThe Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science
This paper presents a theoretical study on the dispersion of gaseous pollutants from a natural gas thermal power plant in the event of a malfunction. Using the Gaussian model, the dispersion of nitrogen oxides generated by such a thermal power plant was ...
