This paper describes the first implementation of POIROT, a web search agent based on relevance, that determines the users interests inspecting the pages bookmarked in the web browser and extracting keywords using some information theory methods such as TF-IDF. The keywords are used to build a training set that is processed by an Inductive Logic Programming(More)
In Neural Networks models the knowledge synthesized from the training process is represented in a subsymbolic fashion (weights, kernels, combination of numerical descriptions) that makes diicult its interpretation. The interpretation of the internal representation of a successful Neural Network can be useful to understand the nature of the problem and its(More)
This paper describes a method for the determination of the four grasping points that are necessary to get a force closure grasp for a planar object considering frictionless contacts. The geometric model of the object is assumed to be unknown. The proposed approach starts from the object boundary obtained from the binary digitalization of an object image,(More)
This paper deals with the problem of reducing water losses during power generation in hydro-power valleys. Because the main resources is water, it is important to guarantee that the demanded power per hour is generated in such a way that water is used as much as possible along the valleys. That is achieved by minimizing the spilling flows. The natural(More)
