The bidirectional neural and hormonal communication system between the brain and the gastrointestinal tract, known as the ‘brain-gut axis’ (BGA), is part of an integrated interoceptive system that continuously conveys homeostatic information about the physiological state of the body to the brain. The homeostatic information is integrated with exteroceptive and interoceptive signals, input from the brain reward system, and affective and ...
This thesis aims at performing crowd monitoring by exploiting signals of opportunity from existing Wi-Fi access points to build a passive radar. Radar processing will be applied on signals that bounced on people (targets) in an environment to obtain a so-called range-Doppler map (RDM) containing the distance and speed information of the targets, as well as an angle spectrum (from MUSIC method) containing the angle-of-arrival of the signals ...
When a person listens to sound, various parts of the auditory system are activated, including the brain. We can then measure the brain waves using EEG, decode them and draw conclusions about the auditory system. We aim to develop a computational model of the auditory system, based on state-of-the art, deep-neural-network-based systems for automatic speech recognition. The model will be constructed by letting people listen to natural speech ...
This thesis aims to exploit a commercial frequency modulated millimetre wave (FMCW) radar and machine learning algorithms to recognise human indoor activity which is a principal feature in many context like patient monitoring and smart homes. This radar operates in the frequency range of 60 Ghz and 64 Ghz and can get the parameters range, velocity and position of each object in its field of view. By using a set of signal processing algorithms ...
The brain is the most complex organ of our body, and a large bulk of research is conducted to understand its basic mechanisms and its impairments associated with neurological deficits. Notably, there are a variety of empirical methods that allow scientists to examine brain functioning. In particular, it is necessary to rely on non-invasive techniques to study brain activity in healthy people and patients. An emerging technique for brain ...
