Viabilidad de la reutilización de aerogeneradores en el noroeste español - Carreño Morales, Rafael María; Comesaña Campos, Alberto; Bouza Rodriguez, Jose Benito; González Piñeiro, Luis
Wind energy is a renewable system of power generation with great potential to be used and it is a sector with good growth prospects. The development of new wind turbine models assumed that the lifetime of machines is constrained; as the power supplied by the turbine is considered small for the state of wind technology. This involves replacing obsolete turbines to adjust production of wind energy to a growing demand. However; these turbines which are considered obsolete still have good performance for reuse in areas with adequate energy demand. An opportunity to reuse these machines is the isolated rural areas...

Micro-world of "the airplane of the muda": A systemic approach to lean - Pérez Rave, Jorge Iván; Cortés Zapata, Sebastián; Restrepo Rico, Daniel
“The airplane of the muda” is a game on a production line, used for practical training on Lean Manufacturing (LM). The aim of this paper is to provide a computer model for the game that approaches it from a systems perspective, to broaden its scope beyond the traditional tactical and operational end, to understanding and strategic decision making. The integration of all this with a challenging case (i.e. maximising cash flow) on an interface in which users can make line balancing decisions, 5S and 5 whys, makes for a computer micro-world on system dynamics. Users can test their hypotheses, receive...

Nuclear quadrupole resonance for explosive detection - Cardona, Lorena; Jiménez, Jovani; Vanegas, Nelson
Nuclear quadrupole resonance (NQR) is a spectroscopic technique that can detect explosives of high
chemical specificity and therefore it is very suitable for the landmine detection problem. There are several
factors affecting the relation of noise signal ratio with NQR: molecular dynamics of relaxation, interference
signals, thermal noise, explosive amount, distance, temperature and the design of the detecting system.
Literature has searched ways for solving one or more of these factors, but since not all the work has been
focused on landmine detection, many have only been tested in simulation or with data obtained under
controlled laboratory conditions, where the detection is not remote (there is...
Extracción de información desde la "web" para identificar acciones de un modelo de dominio en planificación automática - Henríquez Miranda, Carlos; Guzmán Luna, Jaime Alberto
La Planificación Automática (PA) es la disciplina de la Inteligencia Artificial que busca la producción
de una secuencia de acciones que permiten alcanzar un objetivo específico, y que requiere la definición
de un modelo de acción como flujo de entrada. Sin embargo, comenzar la construcción de un modelo de
este tipo es una tarea difícil incluso para expertos. Este trabajo propone extraer información desde la web
para luego identificar los elementos que corresponden a un modelo de acción para tareas de PA, lo que
se busca es analizar un conjunto de páginas web donde se encuentra información en relación con planes
ya producidos que resuelven un...
Evaluation of combustion models for determination of refinery furnaces efficiency - Cala, O. M.; Meriño Stand, L.; Kafarov, Viatcheslav; Saavedra, J.
The efficiency of combustion in furnaces is the measure of heat released in the flame absorbed by the
fluid to be heated and is considered one of the most important variables when conducting studies on
processes that occur in continuous process industries. The furnace efficiency is calculated using various
mathematical models proposed in the literature; these models vary in complexity depending on the
analyzed variables. The models I and II are based on the amount of energy absorbed by the furnace using
the heating value, the model III contains variables such as air excess, stack gas temperature and adiabatic
flame temperature, meanwhile the model IV contains...
Optimización de sistemas simulados a través de técnicas de superficie de respuesta - Oviedo Trespalacios, Óscar Hernándo; Peña-Baena Niebles, Rita Patricia
The purpose of this article is to show the applicability and benefits of the techniques of design of
experiments as an optimization tool for discrete simulation models. The simulated systems are computational
representations of real-life systems; its characteristics include a constant evolution that follows the
occurrence of discrete events along the time. In this study, a production system, designed with the business
philosophy JIT (Just in Time) is used, which seeks to achieve excellence in organizations through waste
reduction in all the operational aspects. The most typical tool of JIT systems is the KANBAN production
control that seeks to synchronize demand with flow of materials, minimize...
Monitoring of carbon steels welded joints by magnetic "Barkhausen" noise - Serna Giraldo, Claudia Patricia; Padovese, Linilson R.
When a variable magnetic field is applied to a ferromagnetic material, it has been observed that, next
to the coercive field (Hc), rise in induction (B) takes place through abrupt jumps known as Barkhausen
jumps. In this research, the microstructure variation in carbon steel welded joints was monitored by the
Magnetic Barkhausen Noise (MBN). The samples were welded by SMAW process, in which both one-pass
and two-pass were applied. Microhardness and microstructure were also characterized. The MBN signal
was measured and analysed by means of several frequency and time domain parameters. Furthermore,
maps of the welded steel surfaces were plotted. The variation of the MBN parameters...
Computational model of Savonius turbine - Palencia Diaz, Argemiro; Jiménez Pajaro, Giovanni; Utria, Khriscia
Although vertical axis turbines have long existed, it was not until the beginning of the twentieth century
when the Darrieus (1921) and Savonius rotors (1924) appeared; the two most used models nowadays.
Savonius rotor was invented by the Finnish engineer Sigurd J Savonius with two half cylinders basic design
that rotate around an axis. In this research, four different models of Savonius rotor blades are analyzed,
as well as the traditional rotor. The principal aim of this research is to find the best Power Coefficient
(Cp) and the best torque coefficient (Cm) for different models. In order to achieve the objective, a CFD
computational model was...
The behavior of West Texas Intermediate crude-oil and refined products prices volatility before and after the 2008 financial crisis: an approach through analysis of futures contracts - Azevedo, Thaís C.; Aiube, Fernando L.; Samanez, Carlos P.; Bisso, Claudio S.; Costa, Letícia A.
By analyzing futures contracts, this paper examines the volatility of West Texas Intermediate (WTI) crude
oil and refined product prices (short, medium and long-term) before and after the financial crisis of 2008.
Daily historical data from January 2000 to June 2008 (pre-crisis period) and from May, 2009 to October,
2012 (post-crisis period) were evaluated. AR-GARCH models were adjusted to these series, with the
purpose of estimating volatilities and the persistence of shocks. After the crisis, the short-term volatility
of the three commodities diminished. The persistence of shocks increased for most contracts after the
2008 crisis. The relevance of this type of analysis is related to the...
A gestão da competitividade industrial por meio da aplicação dos métodos UP e multicritério no setor frigorífico de bovinos - Costa, R.; Siluk, Julio Cezar Mairesse; Neuenfeldt Júnior, A.; Soliman, M.; Nara, E.
The dynamism of the modern world has forced companies to develop many tools and techniques to assist
in the administration. In this sense, the present work aims to show the development of a model capable of
revealing the costs expended to manufacture on a coil cold storage sector, through the application of the
Unit of Production Method, in conjunction with concepts about multi-criteria methods. In order to verify
the behavior in practice, we sought to apply the model in a company located in the state of Rio Grande
do Sul, Brazil between the period from March to August 2012, visualizing in the end that �Sidecut�...
