Using the multi-response method with desirability functions to optimize the zinc electroplating of steel screws
(MDPI, 2018)
info:eu-repo/semantics/article,
Zinc electroplating is a coating process controlled by several input process parameters. However, the commonly used input parameters for setting the process of zinc deposition are current density, temperature of the coating ...
α-Hydroxy ketones as masked ester donors in Brønsted base catalyzed conjugate additions to nitroalkenes
(Wiley, 2018)
Artículo / Artikulua,
The catalyst-controlled enantioselective direct addition reaction of enolizable esters and related carboxylic
acid derivatives to p electrophiles remains a difficult synthetic transformation. In this study, the suitability ...
Normalization through invariants in n-dimensional Kepler problems
(Pleiades Publishing, 2018)
Artículo / Artikulua,
We present a procedure for the normalization of perturbed Keplerian problems in n dimensions based on Moser regularization of the Kepler problem and the invariants associated to the reduction process. The approach allows ...
Oscillatory motions in restricted N-body problems
(Elsevier, 2018)
Artículo / Artikulua,
We consider the planar restricted N-body problem where the N−1 primaries are assumed to be in a central configuration whereas the infinitesimal particle escapes to infinity in a parabolic orbit. We prove the existence of ...
Orness measurements for lattice m-dimensional interval-valued OWA operators
(Elsevier, 2018)
Artículo / Artikulua,
Ordered weighted average (OWA) operators are commonly used to aggregate
information in multiple situations, such as decision making problems or image
processing tasks.
The great variety of weights that can be chosen to ...
Dynamics of axially symmetric perturbed Hamiltonians in 1:1:1 resonance
(Springer, 2018)
Artículo / Artikulua,
We study the dynamics of a family of perturbed three-degree-of-freedom Hamiltonian systems which are in 1:1:1 resonance. The perturbation consists of axially symmetric cubic and quartic arbitrary polynomials. Our analysis ...
Especificidades ion–macromolécula observadas con diversas sales y clara de huevo cocida
(Universidad del País Vasco, 2018)
info:eu-repo/semantics/article,
En este artículo se presentan los resultados de unos sencillos ensayos de solubilidad de la clara de huevo cocido en medios tanto básico como ácido en presencia de distintas sales tales como haluros sódicos y varios cloruros ...
Application of industrial wastes from chemically treated aluminum saline slags as adsorbents
(American Chemical Society, 2018)
info:eu-repo/semantics/article,
In this study, industrial wastes, which remain after aluminum extraction from saline slags, were used as adsorbents. The aluminum saline slags were treated under reflux with 2 mol/dm3 aqueous solutions of NaOH, H2SO4, and ...
Small area estimation of gender-based violence: rape incidence risks in Uttar Pradesh, India
(Society of Statistics, Computer and Applications, 2018)
info:eu-repo/semantics/article,
Violence against women is considered an endemic problem in communities and countries
around the world, and it has been declared an issue of epidemic proportions by the World Health
Organization (WHO). In India, where the ...
Weightable quasi-metrics related to fuzzy sets
(Hacettepe University (Turquía), 2018)
info:eu-repo/semantics/article,
We show that the definition of a fuzzy set is directly related to the existence of a weightable quasi-metric on a universe. This relationship is also explored in terms of functional equations coming either from the membership ...
