Train simulation and headway calculations: an approach based on parametrised continuous curves
(Sin editorial (Madrid, España), 1994-09-09)
The project referred to in this paper consists of three phases. First, the development of a very accurate simulator in order to analyse the train and track performance of a balanced line, to be used as a CAD tool. Second, ...
Energy-saving automatic optimisation of train speed commands using direct search techniques
(Sin editorial (Berlín, Alemania), 1996-07-31)
This paper describes two computer tools that have been developed for the automatic optimisation of train speed commands. Given a target time for the trip between two consecutive stations, energy consumption is minimised. ...
SIRO: an optimal regulation system in an integrated control centre for metro lines
(Sin editorial (Berlín, Alemania), 1996-07-31)
This paper describes the development of the system SIRO, an optimal regulation tool for metro lines. SIRO combines simulation, optimisation and hierarchical control techniques. The objectives of the system are (1) to improve ...
Reordenación de los ejemplos en fuzzy-ARTMAP para ganar robustez y disminuir el número de categorías: Aplicación a la extracción automática de reglas.
(Sin editorial (Murcia, España), 1999-11-19)
One of the drawbacks for the fuzzy-ARTMAP algorithm is its dependence on the order of the training samples. When we want to extract linguistic rules from samples, we need a system able to produce as few rules as posible, ...
Results of the implementation of an optimal control system in an integrated control centre for metro lines
(Sin editorial (Lisboa, Portugal), 1998-08-14)
This paper presents the results of the implementation of an optimal control system for closed metro lines in an integrated control centre. The system has been successfully working for more than one year in metro lines of ...
Prediction of water chemical properties in the cycle of a coal power plant using artificial neural networks
(Sin editorial (Anchorage, Estados Unidos de América), 1998-05-09)
Describes a systematic methodology based on artificial neural networks for model identification and its application to the prediction of water chemical properties under normal operation conditions in a power plant. The ...
A probability estimation based criterion for model evaluation
(Sin editorial (Lausana, Suiza), 1997-09-29)
We develop a criterion based on the estimation of the joint probability density function (pdf) of the input and the error, and on the pdf of the input. It is made to decide when the couple input/model no longer fit together. ...
