Ítem Un acercamiento intertextual al discurso histórico-literario en los cuentos “El historiador problemático" y “Tierra” de Pedro Gómez Valderrama(Universidad EAFIT, 2011) Arroyave Rave, Yovany AlbertoThe work presented below is limited in the debate ancient history / literature. The article suggests as a hypothesis: The proposal of Pedro Gomez Valderrama historical tale, historical discourse and literary discourse is interwoven through the intertext, an intertext that is a mark of the first discourse, immersed and subverted in the second, by their common denominator, the narrative act. In this sense, his short stories evocative historical artifact or work as a mnemonic reference mark of history itself, producing in turn an effect of identity, but, once inserted the historical record (the intertext) in the statute itself acquire literary discourse other colors, other meanings, not far removed from material reality, but confined himself to the status of fictionalization.Ítem Adaptaciones de workflows para administración de seguridad mediante MDD y aspectos(Universidad EAFIT, 2011-06) Giraldo Velásquez, Fáber Danilo; Anaya de Páez, RaquelThis document present a proposal for addressing the problem of workflows adaptation, through the inclusion of security properties at a business modeling level, controlling its impact on the business processes that are intervened, and the management of crosscutting concerns that are woven with each other. The proposal defines how concerns derived from security properties can be managed in a maintainable, reusable and extensible way at model level, according to the context, variations of rules and requirements of business processes, and security standars formulated by distributed services enviroments.Ítem La Administración del Servicio de Formación Universitaria de Directivos de Pequeñas y Medianas Empresas(Universidad EAFIT, 1996) Barriga Manrique, Enrique; Universidad EAFITÍtem Adquisición del léxico(Universidad EAFIT, 1996) Gómez Gómez, Héctor; Universidad EAFITÍtem Algoritmo de tomografía local basado en la transformada discreta Wavelet(Universidad EAFIT, 2011) Alfonso Cristancho, Amed Alfonso; Rojas Cortés, Lucio; Villegas Gutiérrez, Jairo Alberto; Mejía Quiros, Gustavo AntonioÍtem Algoritmos genéticos : una solución alternativa para optimizar el modelo de inventario (Q; r)(Universidad EAFIT, 2009-03) Arias Serna, María Andrea; Londoño Marín, Jorge Iván; Puerta Yepes, María EugeniaÍtem Algunas reflexiones sobre la función de los sindicatos en los mercados de trabajo de la industria maquiladora(Universidad EAFIT, 1997) Cardona A., Marleny; Universidad EAFITÍtem Algunos aspectos de la actividad eléctrica en el tejido cardiaco utilizando elementos finitos(Universidad EAFIT, 2012) Rodríguez M., Edgard; Castellanos M., Fabio; Villegas Gutiérrez, Jairo AlbertoÍtem Algunos aspectos sobre el mercado laboral. Una aproximación teórica y empírica(Universidad EAFIT, 1997) Osorio, Rubén; Universidad EAFITÍtem Algunos elementos para el análisis de datos espaciales : teoría y aplicación(Universidad EAFIT, 2008-06) Acevedo Bohórquez, Ingrid; Gómez Álvarez, Natalia María; Velásquez Ceballos, HermilsonSpatial econometrics is a discipline that utilizes a series of techniques and tools of statistics, algebra, and calculus. Its aim is to evaluate the presence of spatial effects in scenarios of economical and social phenomena and to formulate models that take such effects into account. In order to do so, we identify spatial effects present among the data, such as spatial dependence, spatial autocorrelation, spatial heterogeneity and spatial heteroscedasticity. Exploratory analysis of spatial data proposes that we use adaptations of several traditional graphics that ease the identification of spatial effects. Such graphics that allow discovering patterns between spatial data are box maps, histograms, Moran's maps and scatterplots, frequency maps and histograms. A crucial part of this analysis is the identification of clusters which reveals the form of the concentration of spatial units with similar values for the variable under study. So that the results of the exploratory analysis of spatial data lead to trusty conclusions it is necessary that the employed sample techniques hold some accurate characteristics of region definition. To achieve this, we have to use specific criteria according to the objectives of the underlying studyÍtem Análisis bidimensional axial simétrico de los termoflujos en un tubo de calor(Universidad EAFIT, 2012) Mira Hernández, Carolina; París Londoño, Luis SantiagoÍtem Análisis de eficiencia en los mercados de opciones sobre índices : una aproximación a los mercados emergentes(Universidad EAFIT, 2011) Loaiza Palacio, Daniel; Arbeláez Zapata, Juan CamiloAn efficient capital market is characterized because asset prices reflect the effects of information based on events that have already occurred and on events that the market expects will happen in the future (Fama, 1965). Although the hypothesis of efficiency has been proven in multiple index options markets, it has been conducted mainly in developed markets, and has relied more on the count of violations than on the estimation of returns which are obtained when strategies are implemented to take advantage of market inefficiencies and its comparison with the returns of the market. This study proposes a methodology, based on dynamic programming, for testing the efficiency in emerging markets such as Latin-Americans, and allows a comparison of the test results on a developed market of index options. At the end some recommendations are done to undertake an efficiency test in the future COLCAP index options market in Colombia.Ítem Análisis de incertidumbre en las velocidades de intervalo y en la posición de reflectores obtenidas por migración preapilado en profundidad (PSDM)(Universidad EAFIT, 2010) Becerra Bayona, Carlos Andrés; Agudelo Zambrano, William MauricioThis work studies the interval velocity and reflector position uncertainty on seismic images obtained by Prestack Depth Migration (PSDM). For uncertainty estimation the velocity model should be the best possible one obtained using residual moveout migration velocity analysis techniques. The uncertainty estimation is based on the aperture migration analysis in the wavenumber domain and the diffraction angle for each point in the medium. Due to the migration velocity analysis is an inverse problem with infinite solutions, the uncertainty analysis would help to understand how interval velocity variations are.Ítem Análisis de la calidad de la imagen sísmica en atributos 3D, al aplicar una nueva definición de binning en la migración Kirchhoff pre-apilado(Universidad EAFIT, 2011) Martínez Corredor, Robiel; González Álvarez, HerlingÍtem Análisis de las causas determinantes en el desempeño de los proyectos en Alianza de Servicios Sociales de Caldas(Universidad EAFIT, 2011) Salinas Ávila, Sandra Liliana; Cardona Meza, Luz StellaÍtem Análisis de sensibilidad en el diseño de parámetros de adquisición sísmica 3D3C para el Campo Tenerife(Universidad EAFIT, 2010) Duarte Castro, María Teresa; Andrés E., Calle; Guevara, Saúl E.Ítem Análisis del impacto de los ADR´S de empresas latinoamericanas en sus mercados de valores locales(Universidad EAFIT, 2009) Escobar Berdugo, Alexander; Torres Avendaño, Gabriel IgnacioThe American Depositary Recept (ADR) have presented an interesting development since their creation. In the early of century XX, They have been widely used by South American companies from 80’s decade. Such development have generated a lot of interest concerning to the impact that’s produced by the evaluation for this financial instruments in local stock exchange, and the global integration level which they can generate in growing markets which companies used they for to extend their number of customer and gain monetary resources. In this way, for analyze the impact of these financial instruments on South American stock exchange, analysis are used which are focused in development of local stock Exchange vs. the ADR’s behavior associated to local companies. In this order of ideas through statistics methodologies which improve the temporal structure and observed cross section in this type of stock exchange, The different interactions between North American ADR’s exchange and South American stock exchange which companies use highly this instruments.Ítem Análisis del impacto sociocultural que se genera en las relaciones interpersonales entre la población universitaria foránea y las familias anfitrionas(Universidad EAFIT, 2010) Jaramillo Echeverri, Alina; Echeverri Duque, SandraÍtem Análisis del índice general de las bolsas de valores de Colombia (IGBC), chile (IPSA) y Perú (IGBVL), y sus rendimientos desde la teoría del caos 2001-2011(Universidad EAFIT, 2011) Restrepo Restrepo, Jorge Humberto; Velásquez Ceballos, HermilsonThe purpose of this paper is to examine if exist persistence and chaotic structures in the time series of the Colombian (IGBC), Chile (IPSA) and Peru (IGBVL) stock Exchange Index and their returns, during the period between July 2001 and May 2011. To achieve this goal, the series are tested for nolinearity using the BDS Test, the series memory using the Hurst Exponent, the chaotic dynamics using the Lyapunov Exponent, the self-similarity using the fractal dimension, and the cycles as part of their structure components. The Market Fractal Analysis of the markets was introduced by Edgar Peters in the beginnings 90’s and is based in the Chaos Theory and Fractal Geometry, and it have been an alternative to investigate and analyze financial markets and need less statistical assumptions that other theories like the Efficient Market Hypothesis. This investigation found evidence of persistence and chaotic dynamics systems in the analyzed financial market time series, which suggest that other strategies that could be considered in stock exchange transactions process.Ítem Análisis no lineal de sistemas de control de nivel con algoritmo exponencial polinómico(Universidad EAFIT, 2010-08-15) Navarro Betancur, Guillermo Adolfo; Posada Jaramillo, Ricardo; Castillón, Fabio
