Stochastic Collocation for Optimal Control Problems with Stochastic PDE Constraints [PDF]

open access: yesSIAM Journal on Control and Optimization, 2012
We discuss the use of stochastic collocation for the solution of optimal control problems which are constrained by stochastic partial differential equations (SPDE). Thereby the constraining SPDE depends on data which is not deterministic but random. Assuming a deter- ministic control, randomness within the states of the input data will propagate to the

A Kriging and Stochastic Collocation ensemble for uncertainty quantification in engineering applications

open access: yesEngineering with Computers, 2017
We propose a new surrogate modeling approach by combining two non-intrusive techniques: Kriging and Stochastic Collocation. The proposed method relies on building a sufficiently accurate Stochastic Collocation model which acts as a basis to construct a Kriging model on the residuals, to combine the accuracy and efficiency of Stochastic Collocation ...

Stochastic Collocation Applications in Computational Electromagnetics [PDF]

open access: yesMathematical Problems in Engineering, 2018
The paper reviews the application of deterministic-stochastic models in some areas of computational electromagnetics. Namely, in certain problems there is an uncertainty in the input data set as some properties of a system are partly or entirely unknown.

A numerical approach to solve the stochastic Allen-Cahn equation of fractional order [PDF]

open access: yesMathematics and Computational Sciences, 2021
In this paper, we employ a collocation method based on Legendre polynomials (LPs) to solve the time-fractional stochastic Allen-Cahn equation. This method is applied to convert the solution of this stochastic equation to the solution of a nonlinear ...

Solving Stochastic Nonlinear Poisson-Boltzmann Equations Using a Collocation Method Based on RBFs

open access: yesMathematics, 2023
In this paper, we present a numerical scheme based on a collocation method to solve stochastic non-linear Poisson–Boltzmann equations (PBE). This equation is a generalized version of the non-linear Poisson–Boltzmann equations arising from a form of ...

Multi-quadric collocation model of horizontal crustal movement [PDF]

open access: yesSolid Earth, 2016
To establish the horizontal crustal movement velocity field of the Chinese mainland, a Hardy multi-quadric fitting model and collocation are usually used.

Fully Legendre spectral collocation technique for stochastic heat equations

open access: yesOpen Physics, 2021
For the stochastic heat equation (SHE), a very accurate spectral method is considered. To solve the SHE, we suggest using a shifted Legendre Gauss–Lobatto collocation approach in combination with a shifted Legendre Gauss–Radau collocation technique.
