Analysis of Polynomial Systems with Time Delays via the Sum of Squares Decomposition
Time Delays via Polynomial Systems
2015/6/19
We present a methodology for analyzing robust independent-of-delay and delay-dependent stability of equilibria of systems described by nonlinear Delay Differential Equations by algorithmically constru...
Streaking and Wigner time delays in photoemission from atoms and surfaces
Streaking Wigner photoemission atoms and surfaces
2011/9/13
Streaked photoemission metrology allows the observation of an apparent relative time delay between the detection of photoelectrons from different initial electronic states. This relative delay is obta...
Stability of interconnected impulsive systems with and without time-delays using Lyapunov methods
interconnected impulsive systems Lyapunov methods
2010/11/18
We consider large-scale networks of impulsive systems with and without time-delays and investigate such systems in view of input-to-state stability (ISS). We provide conditions on the size of the tim...
The Impact of Competing Time Delays in Coupled Stochastic Systems
Stochastic synchronization and coordination Time delays Scaling
2010/11/22
We study the impact of competing time delays in coupled stochastic syn-chronization and coordination problems. We consider two types of delays:transmission delays between interacting elements and proc...
Exponential stability of switched systems with mixed time delays
Switching system distributed time delay
2010/9/17
This paper address the exponential stability for a class of switched systems with mixed time delays. Based on linear matrix inequalities and Lyapunov-Krasovskii functional approach, a geometrically sw...
RADAR TIME DELAYS IN THE DYNAMIC THEORY OF GRAVITY
Gravitation-Relativity-Methods analytical-Techiques radar astronomy
2009/3/6
There is a new theory gravity called the dynamic theory, which is
derived from thermodynamic principles in a five dimensional space, radar signals
travelling times and delays are calculated for the ...
Existence and Global Attractivity of Periodic Solutions in $n$-Species Food-Chain System with Time Delays
Time delay Periodic solution Global attractivity
2008/7/1
A delayed periodic n-species simple food-chain system with Holling type-II functional response is investigated. By means of Gaines and Mawhin's continuation theorem of coincidence degree theory and by...
Periodic Solution of a Nonautonomous Diffusive Food Chain System of Three Species with Time Delays
diffusive food chain system positive periodic solution
2007/12/11
By using the continuation theorem of coincidence degree theory, the existence of a positive periodic solution for a nonautonomous diffusive food chain system of three species. { dx_1(t)/dt = x_1(t)[r_...
GLOBAL ASYMPTOTIC STABILITY IN N-SPECIES COOPERATIVE SYSTEM WITH TIME DELAYS
Time delay positive equilibrium point
2007/8/7
The following n-species cooperative system with time delaysis considered in this paper. It is shown that if the system (1) has a unique positive equilibrium point, then it is globally asymptotically s...
