Stability of time-varying systems in the absence of strict Lyapunov functions [PDF]
When a non-linear system has a strict Lyapunov function, its stability can be studied using standard tools from Lyapunov stability theory. What happens when the strict condition fails?

Time-varying modulation systems
In the current communication standards, like WiMAX and LTE, the modulation system has usually fixed symbol block length or fixed subcarrier number. In this study, the authors introduce a new concept, namely time-varying symbol block or time-varying subcarrier number into the modulation systems to improve the system performance. The authors call the new

Further Results on Strict Lyapunov Functions for Rapidly Time-Varying Nonlinear Systems [PDF]
We explicitly construct global strict Lyapunov functions for rapidly time-varying nonlinear control systems. The Lyapunov functions we construct are expressed in terms of oftentimes more readily available Lyapunov functions for the limiting dynamics ...

Quadratic Performance Analysis of Switched Affine Time–Varying Systems
We analyze quadratic performance for switched systems which are composed of a finite set of affine time-varying subsystems, where both subsystem matrices and affine vectors are switched, and no single subsystem has desired quadratic performance.

Metzler asymptotic stability of initial time linear time-varying real-order systems
Determining the asymptotics of many time-varying systems associated with real orders remains a challenging issue in qualitative asymptotic theory. This paper introduces a new concept of Metzler asymptotic stability to linear time-varying real-order ...

Positivity and stability of fractional descriptor time–varying discrete–time linear systems
The Weierstrass–Kronecker theorem on the decomposition of the regular pencil is extended to fractional descriptor time-varying discrete-time linear systems. A method for computing solutions of fractional systems is proposed.

Pattern formation in individual-based systems with time-varying parameters
We study the patterns generated in finite-time sweeps across symmetry-breaking bifurcations in individual-based models. Similar to the well-known Kibble-Zurek scenario of defect formation, large-scale patterns are generated when model parameters are ...

ABSTRACT Background An international Delphi panel of experts developed consensus statements to delineate the circumstances where the risks of dexamethasone as an antiemetic do and do not outweigh its benefits. Procedure Experts in supportive care of pediatric patients were invited to participate.
