Variance-Preserving Estimation of Intensity Values Obtained From Omics Experiments

open access: yesFrontiers in Genetics, 2019
Faced with the lack of reliability and reproducibility in omics studies, more careful and robust methods are needed to overcome the existing challenges in the multi-omics analysis.

Derivation of a Closed-Form Asymptotic Variance for the Coefficient of Variation Under the Reparameterized Birnbaum–Saunders Distribution

open access: yesAxioms
This study develops a tractable, closed-form expression for the asymptotic variance of the coefficient of variation (CV) estimator under a reparameterized Birnbaum–Saunders (BirSau) distribution. Using the method of moments, we derive analytical formulas

Experimental Comparison of Preferential vs. Common Delta Connections for the Star-Delta Starting of Induction Motors

open access: yesEnergies, 2021
Although this is a fact that is not very explored in the literature, there are two possible forms to connect the stator winding of an induction motor in the delta.

Delta Methods in Enveloping Rings, II

open access: yesJournal of Algebra, 1993
Let \(L\) be a Lie algebra over a field of characteristic 0 with universal enveloping algebra \(U(L)\) and let \(L\) act as derivations on an associative algebra \(R\). Let \(\Delta_ L\) be the join of the finite- dimensional ideals of \(L\). In the first part of this paper [ibid.

An Entropy-Based Contagion Index and Its Sampling Properties for Landscape Analysis

open access: yesEntropy, 2014
Studies of spatial patterns of landscapes are useful to quantify human impact, predict wildlife effects, or describe various landscape features. A robust landscape index should quantify two components of landscape diversity: composition and configuration.

A Hybrid Data-Differencing and Compression Algorithm for the Automotive Industry

open access: yesEntropy, 2022
We propose an innovative delta-differencing algorithm that combines software-updating methods with LZ77 data compression. This software-updating method relates to server-side software that creates binary delta files and to client-side software that ...

On the Asymptotic Normality of the Method of Moments Estimators for the Birnbaum–Saunders Distribution with a New Parametrization

open access: yesMathematics
This study investigates the asymptotic properties of method-of-moments estimators for the Birnbaum–Saunders distribution under a newly proposed parametrization.

ACCURACY OF ESTIMATES OF VOLUME FRACTION

open access: yesImage Analysis and Stereology, 2011
When estimating a volume fraction VV from point count fractions PP using Delesse's principle VV = PP, very little information on the accuracy of the estimator can be obtained from the basic theory of stereology.
