Perturbations of Admissibility, Exact Controllability, Exact Observability and Regularity
Zhan-Dong Mei, Ji-Gen Peng
This paper is concerned with the notions of admissibility, exact controllability, exact observability and regularity of linear systems in the Banach space setting. It is proved tha…
On Polynomial Chaos Expansion via Gradient-enhanced -minimization
Ji Peng, Jerrad Hampton, Alireza Doostan
Gradient-enhanced Uncertainty Quantification (UQ) has received recent attention, in which the derivatives of a Quantity of Interest (QoI) with respect to the uncertain parameters a…
Riemann-Liouville Fractional Cosine Functions
Zhan-Dong Mei, Ji-Gen Peng
In this paper, a new notion, named Riemann-Liouville fractional cosine function is presented. It is proved that a Riemann-Liouville -order fractional cosine function is equivale…
A weighted L1-minimization approach for sparse polynomial chaos expansions
Ji Peng, Jerrad Hampton, Alireza Doostan
This work proposes a method for sparse polynomial chaos (PC) approximation of high-dimensional stochastic functions based on non-adapted random sampling. We modify the standard l1…
