Performance of SAE 52100 steel grinding using MQL technique with pure and diluted oil
(Springer, 2019-11-13)
Grinding is one of the highest dimensional accuracy machining processes in the industry. To obtain the smallest form and geometrical workpiece deviation, it is necessary to add cutting fluids as the aim of ensuring the ...
A DFT study of H solubility and diffusion in the Fe-Cr system
(Elsevier, 2018-11)
Density functional theory (DFT) has been used to study the interaction of H with the Fe-Cr system, in particular Fe15Cr. We found that the Cr substitutional atom repeals H; consistently, the H diffusion coefficient is ...
On Goppa codes and Weierstrass gaps at several points
(SpringerDordrechtHolanda, 2005)
El uso del conocimiento en la sociedad
(Facultad de Ciencias Economicas - Universidad Nacional de Colombia, 1999)
La corriente economica principal adolece de dos grandes errores: transplanta los metodos de las ciencias puras en las que se puede obtener y controlar toda la informacion pertinente al estudio de los fenomenos sociales; ...
Split-Plot and Multi-Stratum Designs for Statistical Inference
(Amer Statistical Assoc, 2017-01-01)
It is increasingly recognized that many industrial and engineering experiments use split-plot or other multi-stratum structures. Much recent work has concentrated on finding optimum, or near-optimum, designs for estimating ...
Multinational prediction of household and personal exposure to fine particulate matter (PM2.5) in the PURE cohort study
(ElsevierUSA, 2022-01-15)
Abstract
Introduction
Use of polluting cooking fuels generates household air pollution (HAP) containing health-damaging levels of fine particulate matter (PM2.5). Many global epidemiological studies rely on categorical ...

(Bucaramanga : Universidad de Santander, 2019Facultad de Ciencias de la SaludEnfermería, 2019-11-07)
Es importante reportar la fuente de validez al que se somete el instrumento porque este permite garantizar la valoración por los jueces expertos y ver el nivel de precisión de instrumentos, se evidencio en un estudio del ...
Three-way calibration using PARAFAC and MCR-ALS with previous synchronization of second-order chromatographic data through a new functional alignment of pure vectors for the quantification in the presence of retention time shifts in peak position and shape
(Elsevier Science, 2021-02-15)
In the present contribution is shown the application of the recently developed functional alignment of pure vectors (FAPV) as a proper algorithm to align second-order chromatographic data with severe retention time shifts ...
