[more ▼] Nowadays, satellites are the only monitoring systems that cover almost continuously all possible ocean areas and are now an essential part of operational oceanography. A novel approach based on artificial intelligence (AI) concepts, exploits pasts time series of satellite images to infer near future ocean conditions at the surface by neural networks and genetic algorithms. The size of the AI problem is drastically reduced by splitting the spatio-temporal variability contained in the remote sensing data by using empirical orthogonal function (EOF) decomposition. The problem of forecasting the dynamics of a 2D surface field can thus be reduced by selecting the most relevant empirical modes, and non-linear time series predictors are then applied on the amplitudes only. In the present case study, we use altimetric maps of the Mediterranean Sea, combining TOPEX-POSEIDON and ERS-1/2 data for the period 1992 to 1997. The learning procedure is applied to each mode individually. The final forecast is then reconstructed form the EOFs and the forecasted amplitudes and compared to the real observed field for validation of the method.

[more ▼] In this paper we consider the question of parameter identifiability for biochemical reaction networks, as typically encountered in systems biology. Specifically, we are interested in deriving conditions on the biochemical reaction network and on the measured outputs that guarantee identifiability of the parameters. Taking the specific system structure of biochemical reaction networks into account, we derive sufficient conditions for local parameter identifiability based on a suitable system expansion which does not any more directly depend on the parameters. Rather, as shown, the problem of identifiability can be recast as the question of observability of the (parameter free) expanded system. The conditions derived are exemplified considering a simple example [less ▲] Detailed reference viewed: 14 (2 ULg)Results with INCL4Cugnon, Joseph ; Mancusi, Davide ; et alin Proceedings to the Satellite Meeting on Nuclear Spallation Reactions, International Topical Meeting on Nuclear Research Applications and Utilization of Accelerators 2009 (2010) Detailed reference viewed: 11 (1 ULg) Résumé C.E. n° 211.023, du 3 février 2011, Dalhem et csrts.Delnoy, Michel in Aménagement - Environnement (2011), 3 Detailed reference viewed: 13 (2 ULg)Résumé C.E. n°134.174, du 30 juillet 2004, Masy et LouisDelnoy, Michel in Aménagement - Environnement (2007), 1 Detailed reference viewed: 6 (1 ULg)Résumé C.E. n°137.781, du 30 novembre 2004, commune de Villers-le-BouilletDelnoy, Michel in Aménagement - Environnement (2005), 2 Detailed reference viewed: 7 (0 ULg)Résumé C.E. n°138.907, du 30 décembre 2004, LambinDelnoy, Michel in Aménagement - Environnement (2005), 3 Detailed reference viewed: 5 (1 ULg)Résumé C.E. n°142.165, du 15 mars 2005, De Bolle et csrtsDelnoy, Michel in Aménagement - Environnement (2005), 4 Detailed reference viewed: 1 (0 ULg)Résumé C.E. n°160.013, du 13 juin 2006, Jeanmart et csrtsDelnoy, Michel in Aménagement - Environnement (2007), 1 Detailed reference viewed: 3 (0 ULg)Résumé C.E. n°166.927, du 18 janvier 2007, Marella et csrtsDelnoy, Michel in Aménagement - Environnement (2007), 3 Detailed reference viewed: 3 (0 ULg)Résumé C.E. n°168.730, du 9 mars 2007, SA Gery InternationalDelnoy, Michel in Aménagement - Environnement (2007), 3 Detailed reference viewed: 4 (0 ULg)Résumé C.E. n°170.233, du 19 avril 2007, Hollander et csrtsDelnoy, Michel in Aménagement - Environnement (2007), 4 Detailed reference viewed: 4 (1 ULg)Résumé C.E. n°170.235, du 19 avril 2007, Bellin et MolitorDelnoy, Michel in Aménagement - Environnement (2007), 4 Detailed reference viewed: 6 (2 ULg)Résumé C.E. n°175.035, du 27 septembre 2007, R.T.B.F.Delnoy, Michel in Aménagement - Environnement (2008), 2 Detailed reference viewed: 7 (1 ULg)Résumé C.E. n°175.277, du 2 octobre 2007, SA Gery InternationalDelnoy, Michel in Aménagement - Environnement (2008), 2 Detailed reference viewed: 5 (0 ULg)Résumé C.E. n°175.463, du 8 octobre 2007, ASBL Le Poumon Vert de La HulpeDelnoy, Michel in Aménagement - Environnement (2008), 2 Detailed reference viewed: 7 (2 ULg)Résumé C.E. n°180.553, du 6 mars 2008, Warbecq et BouchezDelnoy, Michel in Aménagement - Environnement (2008), 4 Detailed reference viewed: 7 (1 ULg)Résumé C.E. n°185.114, du 2 juillet 2008, ASBL Le Poumon Vert de La HulpeDelnoy, Michel in Aménagement - Environnement (2009), 1 Detailed reference viewed: 10 (2 ULg)Résumé C.E. n°185.951, du 29 août 2008, de ClercqDelnoy, Michel in Aménagement - Environnement (2009), 2 Detailed reference viewed: 14 (6 ULg)Résumé C.E. n°191.378, du 12 mars 2009, et n°192.200, du 2 avril 2009Delnoy, Michel in Aménagement - Environnement (2009), 1 Detailed reference viewed: 10 (5 ULg) |
