Social robots are a particular category of robots able to perceive in- formation about the environment to reason about the acquired infor- mation with the particular aim to interact with humans. Remarkable applications ...

Since modern cryptography was born around the late 1970s, a myriad of cryptographic constructions and protocols have been proposed. The field quickly developed into a science whose results have had great im pact on people’s ...

Collections of handwritten documents of historical interest are often small, ranging from a few dozen to a few hundred pages, but they may have features typical of the collection itself which make them interesting for ...

The foundation of this thesis is the observation of the usefulness of contextual clues in the context of social robotics: studies prove that human-like behaviour is key to generate in the interlocutor the feeling of empathy ...

This thesis work deals with the problem of learning the topology of a network starting from the signals emitted by the network nodes while executing some distributed processing task. In particular, these signals are generated ...

The main focus of the present work is addressed to the field of organic electronics, which has attracted increasing interest for the development of flexible, large area and low cost electronic applications, from light ...

In this thesis two adaptive Maximum Power Point Tracking (MPPT) techniques for PhotoVoltaic (PV) applications, which are based on two different real-time identification procedures are proposed. The algorithms are implemented ...

The knowledge of the propagation characteristics of the electromagnetic fields is fundamental in the analysis and planning of modern radio communication systems. When the dimensions of the systems are large in terms of the ...

A photovoltaic field is typically composed by series-connected panels, thus composing strings, which are then connected in parallel. By this way, the current and the voltage values of the photovoltaic generator are adapted ...

The formation of a photosensitive device due to the local breakdown in an MOS structure with an impurity containing oxide layer has been observed. A stepwise breakdown of the oxide layer resulted in the formation of a ...
