A Banach spaces-based analysis of a new mixed-primal finite element method for a coupled flow-transport problem
(2020-11)In this paper we introduce and analyze a new finite element method for a strongly coupled flow and transport problem in , , whose governing equations are given by a scalar nonlinear convection–diffusion equation coupled ... -
A bibliometric analysis of aggregation operators
(2019-08)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 ... -
A bibliometric overview of the International Journal of Interactive Multimedia and Artificial Intelligence
(2018)The International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI) published its first issue ten years ago. Currently, IJIMAI is indexed in the important database Emerging Sources Citation Index. This ... -
A branch and cut algorithm for the hierarchical network design problem
(2010)The Hierarchical Network Design Problem consists of locating a minimum cost bi-level network on a graph. The higher level sub-network is a path visiting two or more nodes. The lower level sub-network is a forest connecting ... -
A branch-and-price algorithm for the Vehicle Routing Problem with Deliveries, Selective Pickups and Time Windows
(2010)In the Vehicle Routing Problem with Deliveries, Selective Pickups and Time Windows, the set of customers is the union of delivery customers and pickup customers. A fleet of identical capacitated vehicles based at the depot ... -
A Case Study on EFL Teachers’ Beliefs About the Teaching and Learning of English in Public Education
(2015)Teachers’ beliefs have been a fascinating topic for researchers for the amount of input they can provide for reflection and the improvement of the teaching and learning of English. This case study aims at identifying the ... -
A Century after! Rediscovery of the ancient catfish Diplomystes Bleeker 1858 (Siluriformes: Diplomystidae) in coastal river basins of Chile and its implications for conservation
(2020)The ancient catfish family Diplomystidae, with seven species endemic to rivers of southern South America, represents one of the oldest branches of the diverse order Siluriformes. With most species endangered, new reports ... -
A comparative analysis of intonation between Spanish and English speakers in tag questions, wh-questions, inverted questions, and repetition questions
(2013)The aim of this study was to determine the differences and similarities in intonation when producing tag questions, wh-questions, inverted questions, and repetition questions among native English speakers and ESL Spanish ... -
A comparison of modeling techniques to predict hydrological indices in ungauged rivers
(2018)Predicting the natural flow regime in ungauged rivers is an important challenge in water resource management and ecological research. We developed models to predict 16 hydrological indices in a river network covering the ... -
A compases marciales, desarrollo y vinculación social de las bandas militares del Ejécito chileno 1960-1989
(2019-01-05)Desde la existencia de las primeras civilizaciones y pueblos la música ha existido, y junto con ella se ha acompañado y desarrollado el hombre. Desde amenizar ceremonias, rituales, tradiciones y fiestas, hasta el simple ... -
A complete characterization of strong duality in nonconvex optimization with a single constraint
(2012)We first establish sufficient conditions ensuring strong duality for cone constrained nonconvex optimization problems under a generalized Slater-type condition. Such conditions allow us to cover situations where recent ... -
A conservation law with multiply discontinuous flux modelling a flotation column
(2018-06)Flotation is a unit operation extensively used in the recovery of valuable minerals in mineral processing and related applications. Essential insight to the hydrodynamics of a flotation column can be obtained by studying ... -
A contract for coordinating capacity decisions in a business-to-business (B2B) supply chain
(2015)We address the problem of coordinating the capacity decisions of two autonomous manufacturers engaged in a buyer–supplier relationship. We propose and analyze a supply contract designed to coordinate the companies׳ single ... -
A country's response to tackling plastic pollution in aquatic ecosystems: The Chilean way
(2021-02)Marine plastic pollution is worse than expected, and we are starting to realize its full extent and severity. Solving the plastic pollution problem is not easy, as it requires the action and commitment of all sectors of ... -
A decade later, reviewing floating marine debris in Northern Chilean Patagonia
(2021)Floating marine debris (FMD) were abundantly reported in the Northern Chilean Patagonia in 2009 where sea-based activities (mussel and salmon aquaculture) are responsible for most of them. Identifying the sources of FMD ... -
A design peak flow estimation method for medium-large and data-scarce watersheds with frontal rainfall
(2012)We developed a reliable peak flow estimation method for the design of hydraulic structures. The method is valid in medium-large watersheds (100-5,000 km2) located in Chile between 32°45′ and 43°50′S, with scarcity of ... -
A DFT study on the efficacy of linking agents (Sulfur and Nitrogen) to connect Trans-azobenzene Sandwiched between two Gold Electrodes
(2021)Electronic structure calculations were performed to analyze the effectiveness of linking agents (sulfur and nitrogen) in connecting the trans-azobenzene sandwiched between two gold surfaces (Au-atoms). It was analyzed the ... -
A dual-mixed finite element method for nonlinear incompressible elasticity with mixed boundary conditions
(2007)In this paper we consider the Hu-Washizu principle and propose a new dual-mixed finite element method for nonlinear incompressible plane elasticity with mixed boundary conditions. The approach extends a related previous ... -
A FEM–DtN formulation for a non-linear exterior problem in incompressible elasticity
(2003)In this paper, we combine the usual infinite element method with a Dirichlet-to-Neumann (DtN) mapping, derived in terms of an infinite Fourier series, to study the solvability and Galerkin approximations of an exterior ... -
A framework for mapping and monitoring human-ocean interactions in near real-time during COVID-19 and beyond
