In an effort to efficiently manufacture quality products, numerical models and empirical measurements are used to predict (virtually) the performance of a hearing aid. Finite element analysis is used to study multi-physics processes such as thermo-mechanically induced stress due to heat flow from soldering, acoustic and structural interactions due to transducer vibration, and mechanical shock failure due to drop testing. Following a synopsis of hearing-aid anatomy, the presentation will show numerous animations depicting results from the virtual prototypes.

In this talk, I will present an overview of the numerical models that have been developed during the last few years for the performance prediction of America's Cup yachts. Different aspects which characterize the behaviour of racing boats will be discussed, such as the role of the yacht appendages, the dynamical response of the yacht in calm and wavy seas and the
fluid-structure interaction between wind and sails.

The large megathrust events of 2004 in the Indian Ocean and 2011 in the Japan
Trench have demonstrated that tsunamis pose one of the major coastal hazards to human society.
These events have also identified shortcomings in state-of-the-art numerical models, tsunami
sources considered, as well as standard validation methods for the models.
This has led to the development and efficient parallel implementation on large scale
computer clusters of a new generation of fully nonlinear and dispersive long wave models, as
