Minérographie. Minéraux. Formation et gisements de minerais Résumé : This paper considers the problem of semiglobal stabilization by output feedback for a class of generalized multi-input and multi-output uncertain nonlinear systems. Due to the presence of mismatched uncertainties and the lack of triangularity condition, the systems under consideration are not uniformly completely observable. Combining the output feedback domination approach and block-backstepping scheme together, a series of linear output feedback controllers are constructed recursively for each subsystems and the closed-loop system is rendered semiglobally asymptotically stable.

UV-curable epoxy silicone with a high refractive index and self-photosensitizing effect / Tao Wang in Industrial & engineering chemistry research, Vol. 51 N° 49 (Décembre 2012)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 49 (Décembre 2012) . - pp. 15832-15838 Titre : UV-curable epoxy silicone with a high refractive index and self-photosensitizing effect Type de document : texte imprimé Auteurs : Tao Wang, Auteur ; Hui Ye, Auteur ; Xianshun Zhang, Auteur Année de publication : 2013 Article en page(s) : pp. 15832-15838 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Ultraviolet radiation Résumé : The present work addresses a demand for cationically UV-curable optically transparent monomers and oligomers with high photopolymerization activity and high refractive indexes (RIs). Two novel kinds of epoxy silicones, carbazole-bound epoxy tetramethylcyclotetrasiloxane (Ep-Cz-Si) and carbazole-bound epoxy methylhydrogen silicone oil (Ep-Cz-SiO), were synthesized from 1,3,5,7-tetramethylcyclotetrasiloxane (D4H) and methylhydrogen silicone oil (HHSiO), respectively. Their structures were confirmed by proton nuclear magnetic resonance (1H NMR) and Fourier transform infrared (FT-IR) spectroscopy. Ep-Cz-Si and Ep-Cz-SiO show strong self-photosensitizing effects in photopolymerization and can be photoinitiated directly by a common onium salt photoinitiator under a high-pressure mercury lamp. The RIs of Ep-Cz-Si and Ep-Cz-SiO improve with increasing carbazole content. The photocured networks from Ep-Cz-Si and Ep-Cz-SiO show good thermal stabilities.
