Title:
Sensitivity analysis on chaotic dynamical systems

Abstract:

More scientists and engineers use computer simulations, consequently the sensitivity analysis on the simulated systems is an essential part of that developement. Unfortunately, conventional approaches to compute the sensitivity of a system may fail if the system is chaotic. The results of these methods can be too large, often by orders of magnitude.
In this talk we discuss the Non Intrusive Least Squares Shadowing approach to compute the sensitivity of chaotic dynamical system. This method overcomes the failure of the conventional aproaches and is for many real world applications efficiently computable.
