(PERGAMON-ELSEVIER SCIENCE LTD, 2004-03)The roasting in air of pellets consisting of copper-iron sulphides and limestone and activated limestone has been investigated to explore the possibility of developing a metal production process that eliminates sulphur ...
-
(IOP PUBLISHING LTD, 2006-09)Consider a topological Markov subgroup which is p(s)-torsion (with p prime) and an affine cellular automaton defined on it. We show that the Cesaro mean of the iterates, by the automaton of a probability measure with ...
-
(BLACKWELL, 2006-03-01)According to the latest evidence, the Universe is entering an era of exponential expansion, where gravitationally bound structures will get disconnected from each other, forming isolated 'island universes'. In this scenario, ...
-
(Elsevier Science SA, 2018)This article reports, synthesis and characterization of the ternary Ag/CeO2/ZnO nanostructure which was tested for visible light photocatalytic degradation of industrial textile effluent. The HR-TEM and XPS results confirms ...
-
(Universidad de Chile, 2021)El presente trabajo de investigación consiste en la elaboración de una propuesta de lineamientos para el diseño de edificios de muros prefabricados de hormigón que emulan el comportamiento de las estructuras construidas ...
-
(Universidad de Chile, 2023)La evaluación del desempeño docente pretende la identificación oportuna de fortalezas y debilidades de los profesionales encargados de educar a la ciudadanía de un país para apoyar el desarrollo profesional y mejorar ...

(De Gruyter, 2015)Linear and projective boundaries of Cayley graphs were introduced in [6] as quasi-isometry invariant boundaries of finitely generated groups. They consist of forward orbits g1 D ¹gi W i 2 Nº, or orbits g 1 D ¹gi W i 2 ...
-
(Springer, 2013)This paper is devoted to the study of the symmetric cone linear complementarity problem (SCLCP). Specifically, our aim is to characterize the class of linear transformations for which the SCLCP has always a nonempty and ...
-
(Springer, 2017)We propose a method for simulating linear elastic crack growth through an isogeometric boundary element method directly from a CAD model and without any mesh generation. To capture the stress singularity around the crack ...
-
(Wiley, 2017)The strain smoothing technique over higher order elements and arbitrary polytopes yields less accurate solutions than other techniques such as the conventional polygonal finite element method. In this work, we propose a ...
-
(Society for Industrial and Applied Mathematics Publications, 2019)In this paper we establish that the set of Lipschitz functions f : U → R (U a nonempty open subset of ` 1 d ) with maximal Clarke subdifferential contains a linear subspace of uncountable dimension (in particular, an ...
-
(Elsevier Science BV., 2016-08)Linearity and contiguity are two parameters devoted to graph encoding. Linearity is a generalization of contiguity in the sense that every encoding achieving contiguity k induces an encoding achieving linearity k, both ...
-
(Wiley, 2020)The line generated by two distinct points, x and y, in a finite metric space M=(V,d), is the set of points given by {z is an element of V:d(x,y)=|d(x,z)+d(z,y)|ord(x,y)=|d(x,z)-d(z,y)|}. It is denoted by xy over bar M. A ...
-
(IOS Press, 2015)Traditional approaches for querying the Web of Data often involve centralised warehouses that replicate remote data. Conversely, Linked Data principles allow for answering queries live over the Web by dereferencing URIs ...
-
(Universidad de Chile, 2021)La Web es una enorme plataforma de información, que ha crecido a pasos agigantados durante este milenio. Pero esta información es legible en la medida de que quién la lea sea un humano; las máquinas encargadas de transportar, ...
-
(Springer International Publishing, 2019)© 2018, Swiss School of Public Health (SSPH+).Objectives: To describe and compare the profile of female sex workers (FSWs) that access or do not access sexual health checkups (SHC). The research question was what are the ...
-
(2013)Censuses are one of the most relevant types of statistical data, allowing analyses of the population in terms of demography, economy, sociology, and culture. For finegrained analysis, census agencies publish census microdata ...

(IOP Publishing, 2016-06-10)In a survey of 65 galaxies, Gao & Solomon found a tight linear relation between the infrared luminosity (L-IR, a proxy for the star formation rate) and the HCN(1-0) luminosity (L-HCN). Wu et al. found that this relation ...
