El control sobre los caudales manejados por las empresas de abastecimiento de agua precisa del tratamiento de un número muy elevado de datos, así como la correspondencia de los mismos con la topología de la red de forma coherente con el tiempo de recopilación de los datos. Para responder a esta necesidad se desarrolla la Base de Datos de...

La mejora del aprovechamiento del agua en los sistemas de Abastecimiento exige un control de las medidas de caudal, para contabilizar los volúmenes distribuidos y las pérdidas de agua. Por tanto, se plantea como detectar y corregir los errores de medida sin recurrir a costosas y, a veces prácticamente imposibles, contrastaciones de medida "in...

In this paper, we propose a novel method for Information Extraction (IE) in a set of knowledge in order to answer to user consultations using natural language. The system is based on a Fuzzy Logic engine, which takes advantage of its flexibility for managing sets of accumulated knowledge. These sets may be built in hierarchic levels by a tree...

Las medidas de caudal, volumen o nivel que nos proporcionan información del estado de una red de abastecimiento no verifican de modo exacto las ecuaciones de balance (el volumen medido de agua que entra en un nodo no es igual al volumen medido saliente). La explicación de ello está en la incertidumbre de medida asociada a los distintos...

Solving Term Weighting problem is one of the most important tasks for Information Retrieval and Information Extraction. Tipically, the TF-IDF method have been widely used for determining the weight of a term. In this paper, we propose a novel alternative fuzzy logic based method. The main advantage for the proposed method is the obtention of...

In the current study, an integrated system called SABIO is presented. The current system applies Information Retrieval (IR) techniques developed for collections of textual documents to nontextual corpa. SABIO integrates a fuzzy logic-based procedure for IR. Its search algorithm improves the IR efficiency and decreases the computational burden...

In this paper, we review aspects relevant to industrial standards related to PLC programming: IEC 61131, IEC 61499 and a work about safety developed by the PLCOpen organization based on IEC 61508. We propose to use these standards in PLC learning to fix a common knowhow that allows one to reduce the gap between industry and education, and...
