Input-to-state stability for discrete-time nonlinear systems
The input-to-state stability property and iss small-gain theorems are introduced as the cornerstone of new stability criteria for discrete-time nonlinear systems.
NiagaraCQ: a scalable continuous query system for Internet databases
Continuous queries are persistent queries that allow users to receive new results when they become available. While continuous query systems can transform a passive web into an active environment,
New characterizations of input-to-state stability
New characterizations of the input-to-state stability property are presented and the equivalence between the ISS property and several (apparent) variations proposed in the literature are shown.
A characterization of integral input-to-state stability
The notion of iISS generalizes the concept of finite gain when using an integral norm on inputs but supremum norms of states, in that sense generalizing the linear "H/sup 2/" theory.
A Lyapunov formulation of the nonlinear small-gain theorem for interconnected ISS systems
A Lyapunov statement and proof of the recent nonlinear small-gain theorem for interconnected input/state-stable (ISS) systems is provided.
X-Diff: an effective change detection algorithm for XML documents
This work proposes X-Diff, an effective algorithm that integrates key XML structure characteristics with standard tree-to-tree correction techniques and argues that an unordered model (only ancestor relationships are significant) is more suitable for most database applications.
A converse Lyapunov theorem for discrete-time systems with disturbances
It is shown that a smooth Lyapunov function exists for a family of time-varying discrete systems if these systems are robustly globally asymptotically stable.
Plasmon-induced transparency in metamaterials.
A plasmonic "molecule" consisting of a radiative element coupled with a subradiant (dark) element is theoretically investigated. The plasmonic molecule shows electromagnetic response that closely
Input-Output-to-State Stability
This work establishes a complete equivalence between the IOSS property and the existence of a certain type of smooth Lyapunov function, and obtains characterizations of nonlinear detectability in terms of relative stability and of finite-energy estimates.

It is shown that, in the case of input-to-state stability (ISS)—the output is the state itself-ISS and exp—ISS are in fact equivalent properties, and it is proposed that all solutions of the perturbed system are bounded and the state of the nominal system is captured by an arbitrarily small neighborhood of the origin.
