Subject: UQ for Inverse Problems in Complex Systems, UK, Apr 2018

WORKSHOP: UQ for Inverse Problems in Complex Systems
Isaac Newton Institute, Cambridge
9 - 13 April 2018

Registration for this workshop is open through to 4th February 2018.

It is characteristic of many physical systems that quantities that are
accessible to experimental observation are related through
mathematical models to important characteristics that are not directly
observable. For this reason, the formulation and solution of inverse
problems is a fundamental component of scientific inference and
engineering design using data and models. It is also one of the
fundamental challenges in Uncertainty Quantification, since
uncertainty and stochastic error affects both the observable
quantities and models. Those challenges become very severe when the
systems involved are complex, e.g. incorporating multiple physical
processes acting over a range of scales.

The workshop will be devoted to exploring the challenges associated
with stochastic inverse problems for complex systems. The workshop
will be organized around a set of themes: (1) Formulation, solution,
and use of inverse problems for large complex systems; (2) Bayesian
model calibration; (3) Efficiency and accuracy in computational
methods for stochastic inverse problems; and (4) Experimental
design. We will also organize a discussion exploring the possibility
of establishing a set of community challenge problems.

Please see the workshop webpage for registration details. Limited
funding is available to support PhD students. There will be a poster
session. Priority for funding will be given to those students
submitting posters. Note that the organisers are not accepting
contributed talks.

This workshop is the fourth event in a six-month programme on
Uncertainty Quantification at the Isaac Newton Institute, see .

Subject: Short Course, Hybridized Discontinuous Galerkin Methods, USA, Jul 2018

I will offer a short course on Hybridized Discontinuous Galerkin
methods for PDEs at WCCM 18 July 22-27, 2018
in New York City. The objective of the short course is attached below
and the details can be found here

In this short course, we present a systematic and constructive
derivation of hybridized discontinuous Galerkin (HDG) methods using an
upwind framework. The key behind our construction is the Godunov
method and the Rankine-Hugoniot condition. We will show in details the
construction of an upwind HDG framework and its application to
constructively derive HDG methods for a large class of partial
differential equations (PDEs) including elliptic, parabolic,
hyperbolic, and mixed-types PDEs. The participants will learn how to
apply this framework to derive HDG methods for
convection-diffusion-reactions equations (and its subsets), Maxwell
equations, and linearized shallow water equation. The well-posedness
of the HDG framework will be discussed and the well-posedness analysis
of the HDG formulation for the convection-diffusion-reaction will be
carried out in details. The participants will learn a step-by-step
convergence analysis of the HDG method for the linearized shallow
water equations. We will discuss the extension to nonlinear systems
and active research topics.

At the end of the short course, participants will, without wary, be
able to construct HDG methods for their applications of interest. They
will learn how HDG is implemented in practice and accompanied HDG
Matlab codes will be provided at end of the short course.
