(Blackwell Publishing Inc., 2019)© 2019 Special Care Dentistry Association and Wiley Periodicals, Inc.Cerebral palsy (CP) is a condition caused by brain damage before, during, or shortly after birth. Communication can be a challenge when treating patients ...
-
(IOP Publishing, 2018)Star formation is a multi-scale process that requires tracing cloud formation and stellar feedback within the local (less than or similar to kpc) and global galaxy environment. We present first results from two large ...
-
(Springer, 2018)The main goal of this paper is to propose a Bayesian based methodology for implementing robot informed search for objects. The methodology uses convolutions between observation likelihoods of secondary objects and spatial ...
-
(IEEE, 2017)The interferometry problem addresses the estimation of an unknown quantity exploiting the interference among measurements from different sources. These measurements are obtained from the Fourier domain but are sparse and ...
-
(Editorial Board EJTIR, 2020)In a rapidly changing world, transportation is a big determinant of quality of life, financial growth and progress. New challenges (such as the emergence of the COVID-19 pandemic) and opportunities (such as the three ...
-
(Elsevier Ltd, 2019)Aggregation operators consist of mathematical functions that enable the combining and processing of different types of information. The aim of this work is to present the main contributions in this field by a bibliometric ...
-
(Routledge, 2019)Purpose: As part of the recognition of the 25th anniversary of the Journal of Business-to-Business Marketing (JBBM), this paper presents an overview of the JBBM through a bibliometric analysis (BA) of its content from 1992 ...
-
(Elsevier, 2017)Mixed integer optimization formulations are an attractive alternative to solve Stackelberg Game problems thanks to the efficiency of state of the art mixed integer algorithms. In particular, decomposition algorithms, such ...
-
(PERGAMON-ELSEVIER, 2012-09)A multi-period stochastic model and an algorithmic approach to location of prison facilities under uncertainty are presented and applied to the Chilean prison system. The problem consists of finding locations and sizes of ...
-
(EDP Sciences, 2021)The frequency of Earth-sized planets in habitable zones appears to be higher around M-dwarfs, making these systems exciting laboratories to investigate planet formation. Observations of protoplanetary disks around very ...
-
(Universidad de Chile, 2019)Dentro de la ingeniería estructural, el monitoreo de condición usando diferentes tipos de sensores ha sido importante en la prevención de fallas y diagnóstico del estado de salud. El desafío actual es aprovechar al máximo ...
-
(Elsevier, 2017)In this paper, a family of high-order space-time polynomials in the context of continuous and discontinuous Galerkin methods is proposed. The resulting Galerkin schemes are used as a building block in ADER methods for ...
-
(WILEY-BLACKWELL, 2007-12-21)We report a centimetre-wave (cm-wave, 5-31 GHz) excess over free-free emission in planetary nebulae (PNe). Accurate 31- and 250-GHz measurements show that the 31-GHz flux densities in our sample are systematically higher ...
-
(2007)Let (Xn) be a sequence of nonnegative, integrable, independent and identically distributed random variables, with common distribution function F. We consider the problem of finding all distribution functions F such that ...
-
(Elsevier B.V., 2018)This research describes the development of a very cheap mesoporous silica material similar to hexagonal mesoporous silica (HMS) and using a silicate extract as precursor. This precursor is obtained from cheap fly ash by ...
-
(IOP Publishing, 2018-09)IC 166 is an intermediate-age open cluster (OC) (similar to 1 Gyr) that lies in the transition zone of the metallicity gradient in the outer disk. Its location, combined with our very limited knowledge of its salient ...
-
(Nature Publishing Group, 2018)Every star-forming galaxy has a halo of metal-enriched gas that extends out to at least 100 kiloparsecs(1-3), as revealed by the absorption lines that this gas imprints on the spectra of background quasars(4). However, ...
-
(Nature, 2021)The Chile Triple Junction, where the hot active spreading centre of the Chile Rise system subducts beneath the South American plate, offers a unique opportunity to understand the influence of the anomalous thermal regime ...
-
(Elsevier B.V., 2019)In this paper we formulate an integer programming model for the Location and Routing Problem with Pickup and Delivery. We propose a column generation scheme and implement, for the subproblem, a label-setting algorithm for ...
-
(Elsevier, 2016)The high penetration of renewables envisaged for future power systems will significantly increasethe need for flexible operational measures and generation technologies, whose associated investmentdecisions must be properly ...
