Asymptotic properties of statistical estimators using multivariate Chi-squared measurements
(Academic Press Inc Elsevier Science, 2020-08)
This paper studies the problem of estimating a parameter vector from measurements having a multivariate chi-squared distribution. Maximum likelihood estimation in this setting is unfeasible because the multivariate chi-squared ...
Statistical analysis of the main incremental forming-SPIF process parameters that contribute to the change the roughness in an experimental geometry
(FEDERACION ASOCIACIONES INGENIEROS INDUSTRIALES ESPANA, 2016-11-01)
Over time the process of incremental deformation of sheet metal without matrix in its variant (SPIF), has been developed in different countries with the aim of meeting the needs of flexible production with no investment ...
Treatment of automotive industry oily wastewater by electrocoagulation: statistical optimization of the operational parameters.
(IWA PUBLISHING, 2009-11-01)
An electrocoagulation process was used for the treatment of oily wastewater generated from an automotive industry in Medellin (Colombia). An electrochemical cell consisting of four parallel electrodes (Fe and Al) in bipolar ...
Generalized statistical description of adsorption of polyatomics
(Elsevier Science, 2005-12)
Multisite-occupancy adsorption is described as a fractional statistic problem, based on Haldane’s statistics. Site exclusion is characterized by a statistical exclusion parameter, g, which relates to the molecular size and ...
Astrophysical properties of star clusters in the Magellanic Clouds homogeneously estimated by ASteCA
(EDP Sciences, 2017-06)
Aims. We seek to produce a homogeneous catalog of astrophysical parameters of 239 resolved star clusters, located in the Small and Large Magellanic Clouds, observed in the Washington photometric system. Methods. The cluster ...
Extracting chemical information from high-resolution Kβ X-ray emission spectroscopy
(Pergamon-Elsevier Science Ltd, 2018-06)
High-resolution X-ray emission spectroscopy allows studying the chemical environment of a wide variety of materials. Chemical information can be obtained by fitting the X-ray spectra and observing the behavior of some ...
Tsallis' deformation parameter q quantifies the classical-quantum transition
(Elsevier Science, 2009-05)
We investigate the classical limit of a type of semiclassical evolution, the pertinent system representing the interaction between matter and a given field. On using Tsallis q-entropy as a quantifier of the ensuing dynamics, ...
The removal of the trivalent chromium from the leather tannery wastewater: the optimisation of the electro-coagulation process parameters.
(IWA PUBLISHING, 2011-02-01)
The capacity of the electro-coagulation (EC) process for the treatment of the wastewater containing Cr3+, resulting from a leather tannery industry placed in Medellin (Colombia), was evaluated. In order to assess the effect ...
