A method for reducing errors of downwind sail simulations is presented. This method can be used to improve the results of any simulation making use of Computational Fluid Dynamics (CFD) models and is particularly useful when simplified CFD models are considered, as in these cases the error of the results achieved can be large. In the present approach, in order to reduce the error the results are corrected...
The objective of this paper is to report on new developments in the project we are working on for the development of a mobile sensor based opportunistic urban pollution monitoring network. This work follows from the implementation of a single pollution sensor based sensing node prototype which was used for testing an opportunistic communications network and which was reported elsewhere. Here we concentrate...
Detecting changes in the behavior of users can serve as an indicator of malicious or damaging misuse in many services; including the possible usurpation of a regular user identity by an intruder. For these purposes, approaches based on the profiling of users are not as common as those based on the analysis of the system behavior. This paper presents a method for automatically profiling and subsequently...
An approach for considering spatio-spectral information when classifying inhomogeneous materials in industrial environments is proposed. Its main application would be in the inspection and quality control tasks. They system core is an ANN based hyperspectral processing unit able to perform the online determination of the quality of the material based on its composition and grain size. A training adviser...
