Ítem Water flows modelling and forecasting using a RBF neural network(Universidad Icesi, 2008-12-17) Fajardo Toro, Carlos Hernán; Fernández Riverola, Florentino; Soto González, Benedicto; González Peña, DanielA hydrologic estimation model base on the utilization of radial basis function neural networks is presented, in which the aim is to forecast stream flows in an automated fashion. The problem of river flow forecasting is a non-trivial task because (i) the various physical mechanisms governing the river flow dynamics act on a wide range of temporal and spatial scales and (ii) almost all mechanisms involved in the river flow process present some degree of nonlinearity. The proposed neural network was used to forecast daily river discharges in a river basin providing satisfactory results and outperforming previous.Ítem BotBlog: una propuesta de integración de bitácoras y agentes(Universidad Icesi, 2010-11-25T22:11:25Z) Fajardo Toro, Carlos Hernán; González Moreno, Juan Carlos; Ramos Valcárcel, DavidThe adaptation to european space for higher education is a fact that should be assumed by everybody and whose process is being carried out. To proceed in this adaptation will be mandatory the implementation of on new informatics tools. This paper proposes the dynamic development of a thematic portal through chatterbots with blogs. The portal is built and evolves on the client browser window based on the questions asked, the pre-established answers, the contents provided by internet search and by the linked blogs.
