Graduates of the University of Calgary's Geomatics Engineering program shall be exempted from writing all Core subjects, and listed Elective examinations provided they passed

Definition 4. Indeed he related the almost asymptotic stability to the existence of a density function which plays the role of a Lyapunov function for the closed-loop system.

For general time-varying systems, it is established that existence of an “Output Robust Control Lyapunov Function” implies existence of continuous time-varying feedback

To establish the spectrum determined growth condition, we show that system (1.4) is a Riesz system in that sense that: the multiplicities of all eigenvalues are uniformly bounded

In order to do so, compare the free energy of a perfectly ordered system with the free energy of a partially disordered case that introduces the less energetic frustrations

And finally, a multitude of papers have recently been published on fundamental characterizations and criteria for input-to-state stability [15, 17–19, 30, 31] and for versions

More precisely, he says the following: there exists non-real eigenvalues of singular indefinite Sturm-Liouville operators accumulate to the real axis whenever the eigenvalues of

Banica introduced the notions of dephased and undephased de- fects for matrices F G , and showed that they give upper bounds for the tangent spaces at F G to the real algebraic
