Algebraic observer for a class of switched systems with zeno phenomenon
For a large class of switched systems with zeno phenomenon, classical observer cannot be applied directly since the terms leading to zeno phenomenon are not derivable. However in t...

Extended nonlinear observable canonical form for multi-output dynamical systems
— In this paper, we give sufficient conditions which guarantee the existence of a diffeomorphism in an extended state space that allows to transform a multi-output nonlinear dyn...

The Tripartite Separability of Density Matrices of Graphs
The density matrix of a graph is the combinatorial laplacian matrix of a graph normalized to have unit trace. In this paper we generalize the entanglement properties of mixed dens...

A Theory of Redo Recovery
Our goal is to understand redo recovery. We define an installation graph of operations in an execution, an ordering significantly weaker than conflict ordering from concurrency co...

Maximum-likelihood Kalman filtering for switching discrete-time linear systems
— State estimation is addressed for a class of discrete-time systems that may switch among different modes taken from a finite set. The system and measurement equations of each ...
