A comparison of trajectory granular based algorithms for the location-routing problem with heterogeneous fleet (LRPH)
(Universidad Nacional de Colombia, 2017)We consider the Location-Routing Problem with Heterogeneous Fleet (LRPH) in which the goal is to determine the depots to be opened, the customers to be assigned to each open depot, and the corresponding routes fulfilling ... -
A conceptual study of a self-centering semi-rigid connection with energy dissipation for wooden frames
(Brazilian Association of Computational Mechanics, 2020)A proposal of a semi-rigid self-centering connection for the seismic protection of wooden structures is studied. An analytical model for the characterization of the response of the connection is developed. Quasi-static ... -
A crowdsourcing-based system for monitoring em radiation exposure in Chile
(CEUR-WS, 2018-10)Public concern about the possible effects on health due to electromagnetic (EM) radiation exposure has led to the definition of regulations worldwide. In Chile, the so-called "Ley de Antenas" provides a regulatory framework ... -
A dynamic linguistic decision making approach for a cryptocurrency investment scenario
(Institute of Electrical and Electronics Engineers Inc., 2020-12)Cryptocurrencies have been receiving the sustained attention of investors since 2009. These new investment vehicles are digitally native, meaning that they are traded exclusively on 24/7 digital platforms. Consequently, ... -
A flexible mathematical model for the planning and designing of a sporting fixture by considering the assignment of referees
(Growing Science, 2019-04)This paper deals with the problems faced with the designing and planning of a sporting fixture considering correct referee assignments. A non-linear binary program model is proposed to solve the problems, which aims to ... -
A geodynamic model linking Cretaceous orogeny, arc migration, foreland dynamic subsidence and marine ingression in southern South America
(Elsevier B.V., 2018-10)This study synthesizes the tectonomagmatic evolution of the Andes between 35°30′S to 48°S with the aim to spotlight early contractional phases on Andean orogenic building and to analyze their potential driving processes. ... -
A Hybrid FCS-MPC With Low and Fixed Switching Frequency Without Steady-State Error Applied to a Grid-Connected CHB Inverter
(Institute of Electrical and Electronics Engineers Inc., 2020-12)This paper presents a new finite control set model predictive control strategy that, contrary to conventional approaches, achieves (i) zero steady-state error in the converter's AC current, and (ii) both fixed and lower ... -
A Late Eocene age proposal for the Loreto Formation (Brunswick Peninsula, southernmost Chile), based on fossil cartilaginous fishes, paleobotany and radiometric evidence
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2012-01)ABSTRACT. We present new data on the paleoichthyology, paleobotany and radiometric results of the Loreto Formation in the Brunswick Peninsula of southernmost Chile, that allow us to propose a Late Eocene age. The rich ... -
A middleware for creating physical mashups of things
(CEUR-WS, 2017)Nowadays, “things” deployed in cities are crucial to gather data to support decision making systems. Unfortunately, there is a low level of reuse of “things” between smart city applications of different organizations because ... -
A model for solving the dynamic vehicle dispatching problem with customer uncertainty and time dependent link travel time
(Facultad de Ingeniería, Universidad de Antioquia, 2012)In a real world case scenario, customer demands are requested at any time of the day requiring services that are not known in advance such as delivery or repairing equipment. This is called Dynamic Vehicle Routing (DVR) ... -
A Novel Constraint Programming Decomposition Approach for the Total Flow Time Fixed Group Shop Scheduling Problem
(MDPI, 2022-02)This work addresses a particular case of the group shop scheduling problem (GSSP) which will be denoted as the fixed group shop scheduling problem (FGSSP). In a FGSSP, job operations are divided into stages and each stage ... -
A practical methodology of design of off-line reservoirs for reducing maximum water levels in urban channels
(Elsevier B.V., 2020-08)Flooding can often occur in many places due to the increasing trend of rainfall events (climate change), the urbanization process of a catchment area, or by an undersized urban channel. Reservoirs are used for limiting ... -
A revised interpretation of the Chon Aike magmatic province: Active margin origin and implications for the opening of the Weddell Sea
(Elsevier B.V., 2021-04)Late Triassic – Jurassic igneous rocks of the Antarctic Peninsula and Patagonia provide evidence for the evolution of the margin of southwestern Gondwana. We present new geochronological (LA-ICP-MS zircon U—Pb dates) ... -
El abate Juan Ignacio Molina: una vida dedicada a la historia natural y civil del reino de Chile
(Asociación Geológica Argentina, 2011-09)Juan Ignacio Molina (1740-1829) nació cerca de Talca, Chile, y falleció en Bolonia, Italia. Es el primer científico chileno. Desde pequeño se interesó por la naturaleza. Se educó con la Compañía de Jesús en diversos lugares ... -
Activity of alumina supported fe catalysts for N2O decomposition: Effects of the iron content and thermal treatment
(Sociedad Chilena de Quimica, 2017)The activity of Fe2O3/Al2O3 catalysts prepared by impregnation of Al2O3 with different amounts of Fe and calcination temperatures (650 and 900 °C) in the direct N2O decomposition reaction was studied. High calcination ... -
Adsorption of biosolids and their main components on chalcopyrite, molybdenite and pyrite: Zeta potential and FTIR spectroscopy studies
