On the use of the BLYP functional for the DFT calculation of graphite-hydrogen systems
(2010)This letter focuses on a possible pitfall that can occur in the DFT calculation of graphite-hydrogen interactions under tokamaks conditions. Calculations based on the BLYP functional, in fact, result in a stable -C2H3 group ...

Partial state observers for linear systems with unknown inputs
(2008)We consider the problem of constructing partial state observers for discrete-time linear systems with unknown inputs. Specifically, for any given system, we develop a design procedure that characterizes the set of all ...
