Lagrangian Averaging, Nonlinear Waves, and Shock Regularization [PDF]

, 2005
In this thesis, we explore various models for the flow of a compressible fluid as well as model equations for shock formation, one of the main features of compressible fluid flows.

Bayesian inverse problems for functions and applications to fluid mechanics [PDF]

, 2009
In this paper we establish a mathematical framework for a range of inverse problems for functions, given a finite set of noisy observations. The problems are hence underdetermined and are often ill-posed.

Computer Methods in Applied Mechanics And Engineering

, 2022
Krylov subspace recycling is a powerful tool when solving a long series of large, sparse linear systems that change only slowly over time. In PDE constrained shape optimization, these series appear naturally, as typically hundreds or thousands of ...

Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

International Journal of Adaptive Control and Signal Processing, EarlyView.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Design and analysis of propeller blade geometry using the PDE method [PDF]

, 1993
This thesis aims to incorporate geometric and functional design of surfaces using a method known as the PDE method. In particular, it will be demonstrated how the PDE method can be extended to represent an existing marine propeller geometry ...
