Substructuring techniques and pROMs for the optimization of a MEMS voice recognition device
This thesis aims to develop strategies to alleviate the computational burden of optimising a novel, purely mechanical voice recognition device. The device is composed of many repeated cells, each slightly varied through parametric optimisation of a high-fidelity finite element model with millions of degrees of freedom. Direct simulation of such models is computationally prohibitive, making

Transcranial focused ultrasound via metamaterial engineering
DETAILS: the aim of this project is to study a metamaterial structure capable of focusing ultrasound from outside to the inside the skull. In this field, the state-of-the-art ultrasound technology features a hemispherical transducer array with many piezoelectric elements operating around a central frequency of 650 kHz. By leveraging complex electronic circuits the system allows
