1. Evidence for "liveness" in face biometrics
Abstract : Aliveness or "liveness" detection is a novel but crucial topic in biometrics. In this study we will investigate it for face biometrics. The problem is given by the real-time requirements of such a system to be able to avert advanced spoofing attempts, e.g. READ MORE

2. Scanning tunneling microscopy and photoemission studies of Ag films on metal/semiconductor surfaces
Abstract : The research presented in this thesis has been focused on the study of thin Ag films, grown on metal-reconstructed Si(111) and Ge(111) surfaces.The films have been grown at room temperature, and the morphologiesand electronic structures of the films have been investigated using scanning tunneling microscopy and spectroscopy (STM/STS), low-energy electron diffraction (LEED) and angle-resolved photoelectron spectroscopy(ARPES).
