Iterative learning control of multivariable uncertain nonlinear systems with nonrepetitive trajectory

Mohamed Bouri

Iterative learning control (ILC) theory is based on the traditional assumptions of resetting condition and repetitive trajectory. To overcome these restrictions, a novel ILC is developed in this paper for MIMO uncertain nonlinear systems subject to externa ...

Excited State Dynamics of Thiophene and Bithiophene: New Insights into Theoretically Challenging Systems

Anne-Clémence Corminboeuf, Basile Curchod, Antonio Prlj

The computational elucidation and proper description of the ultrafast deactivation mechanisms of simple organic electronic units, such as thiophene and its oligomers, is as challenging as it is contentious. A comprehensive excited state dynamics analysis o ...
