Rejish defending his thesis on Microsoft Teams

Rejish Jesudasan successfully defends his thesis

22 May 2020

Rejish Jesudasan successfully defended his thesis on "An Adaptive Parametrisation Method for Shape Optimisation Using Adjoint Sensitivities". Owing to COVID-19 / SARS-CoV-2, the viva was conducted over video conferencing, but even with noise of his ceiling fan (essential in his Indian home at this time), the finer details of his algorithm ...

Siamak Akbarzadeh successfully defends PhD thesis

6 December 2019

Siamak Akbarzadeh successfully defended his thesis on using Automatic Differentiation software tools to obtain adjoint variants of the incompressible SIMPLE scheme. Adjoint methods are essential for numerical optimisation of many-parameter systems with expensive models, such as CFD. Siamak's work is a step forward in deriving robust adjoints for the widely ...

P. Mohanmuraly and J-D Mueller

Successful PhD examination

11 March 2019

Pavanakumar Mohanamuraly successfully defended his thesis on "Fast Adjoint-assisted Multilevel Multifidelity Method for Uncertainty Quantification of the Aleatoric Kind" His work uses Monte-Carlo methods to compute the effect of uncertainties due to manufacturing. Current methods work well for up to handful of uncertain parameters, but their computation cost increases dramatically ... [more]
