(ELSEVIER, 2005-07-15)This review paper aims to present a practical, integrated procedure for the prediction of sediment transport rates in both the continental and marine environment, based on the settling velocity of particles. Such studies ...
-
(Routledge, 2017)The purpose of this paper is to comprehend the importance that grammar has in the teaching of writing in the Hispanic American countries and Spain. To achieve this, the discussion that has taken place in these countries ...
-
(Elsevier, 2017)Sequence representations supporting not only direct access to their symbols, but also rank/select operations, are a fundamental building block in many compressed data structures. Several recent applications need to represent ...

-
(Springer, 2022)Compared to other features of the human body, voice is quite complex and dynamic, in a sense that a speech can be spoken in various languages with different accents and in different emotional states. Recognizing the gender, ...
-
(Universidad de Chile, 2019)Los granitoides orbiculares son rocas inusuales. Se caracterizan por el crecimiento radial y/o tangencial de capas concéntricas de minerales félsicos y/o máficos alrededor de núcleos centrales de textura y mineralogía ...

(Association for Computing Machinery, 2017)Graph databases make use of logics that combine traditional first-order features with navigation on paths, in the same way logics for model checking do. However, modern applications of graph databases impose a new requirement ...
-
(Elsevier, 2020)In this paper we study the reconstruction problem in the congested clique model. Given a class of graphs g, the problem is defined as follows: if G is not an element of g, then every node must reject; if G is an element ...
-
(Universidad de Chile, 2018)Chile es el país mas largo del mundo con sobre 4300 km de longitud y un ancho promedio de 180 km. Armar una red que abastezca de internet al país naturalmente tiende a unir del extremo norte al extremo sur. Esta tendencia ...
-
(Elsevier, 2020)Highly pure zinc oxide nanoparticles (ZnO NPs) and graphene-zinc oxide nanocomposites (G-ZnO NCs) were synthesized via chemical precipitation method. The structure, morphology, and composition of the synthesized ZnO NPs ...
-
Graphene/nickel oxide nanocomposites against isolated ESBL producing bacteria and A549 cancer cells (Elsevier Ltd, 2019)The synthesis of nickel oxide nanoparticles (NiO NPs)and graphene/nickel oxide nanocomposites (Gr/NiO NCs)was performed using a simple chemical reduction method. Powder X-ray diffraction (XRD)and thermogravimetric analysis ...
-
(Springer, 2015)The paper concerns parameterized equilibria governed by generalized equations whose multivalued parts are modeled via regular normals to nonconvex conic constraints. Our main goal is to derive a precise pointwise second-order ...
-
(Elsevier, 2017)A connected graph G=(V,E) with m edges is called universal antimagic if for each set B of m positive integers there is an bijective function f:E→B such that the function f˜:V→N defined at each vertex v as the sum of all ...
-
(Elsevier, 2020)Hartsfield and Ringel in 1990 conjectured that any connected graph with q >= 2 edges has an edge labeling f with labels in the set {1,..., q}, such that for every two distinct vertices u and v, f(u) not equal= f(v), where ...
-
(Universidad de Chile, 2016)SLAM (Simultaneous Localization and Mapping) es el problema de estimar la posición de un robot (u otro agente), y simultáneamente, generar un mapa de su entorno. Es considerado un concepto clave en la robótica móvil, y ...
-
(Wiley, 2017)Subduction zones provide direct insight into plate boundary deformation and by studying these areas we better understand tectonic processes and variability over time. We studied the structure of the offshore subduction ...
-
(IOP PUBLISHING LTD, 2013-06-20)We study the gravitational stability of gaseous streams in the complex environment of a galaxy merger, because mergers are known to be places of ongoing massive cluster formation and bursts of star formation. We find ...
