Description:
Background: Meniere disease is a disorder of the inner ear that causes severe and debilitating vertigo, hearing loss, and fullness or congestion in the ear. It affects approximately 12 out of every 1,000 people, from 20 to 60 years.
The problem: Although the cause of Meniere disease is well known (buildup of fluid in the labyrinth), no definite answers are available on the many reasons why only some people develop the disease; the treatment options are many, inlcuding medications, surgery, pressure treatments, but the clinical efficacy of these options is not the same for all patients, as it highly depends on the accuracy with which the etiology of the disease has been determined for each single case.
The proposed solution: Objectives of the Thesis are: 1) To develop an automated procedure for clinical text analytics based on Information Extraction able to identify, extract and organize clinical information from the textual medical records that may explain the etiology of the disease (past and present symptoms, medical evidences, signs, past and present treatments, etc); 2) To develop a Clinical Decision Support system that based on the textual information extracted in (1) and on the quantitive (numerical) data from clinical audiometric tests and medical imaging (CT and MR scans) will support the doctor in the differential diagnosis of the disease; 3) To integrate in the System developed in (2) a treatment module to identify clusters of patients with similar treament outcomes and thus support the doctor in planning the best personalised plan for Meniere disease treatment.

Description:
Background: Tinnitus (i.e., ringing in the ears) is a symptom that affects nearly 1 in 5 people and may seriously impact the quality of life of sufferers. A range of options are available to mask or distract from the tinnitus, to manage the psychosocial impacts, reduce stress, or to address common comorbidities such as depression, anxiety and insomnia.
The problem: There is a lack of high-level evidence for the clinical efficacy of these different management options. Also, tinnitus-related variables fluctuate substantially over the day, thus it is important to gather the outcomes of tinnitus clinical management in real life (i.e. not in the laboratory) and in real time (i.e. not a single snap shot).
The proposed solution: Objectives of the Thesis are: (1) to develop an innovative platform for collecting real-life and real-time health data through Ecological Momentary Assessment (EMA), and (2) to analyse those variables using Machine Learning to identify a global measure of the outcomes that include but are not restricted to general health, concomitant medications, hearing status, lifestyle, personality, tinnitus-related beliefs, and treatment outcome expectations.

Description:
This thesis will be done in collaboration with Security Pattern ( https://www.securitypattern.com). IoT is increasingly implemented using devices that might store sensitive information but otherwise work in an hostile environment. One of the most effective class of attacks that can be used to steal such sensitive information is implemented through a side-channel. A side-channel attack exploits a physical, measurable property of an otherwise secure implementation to exfiltrate sensitive data. Main examples are timing attacks, power analysis, electromagnetic analysis and fault injection. This thesis proposal aims at improving and extending the current hardware/software tools to implement an attack. The goal is to provide IoT designers with a easy to use device and software to find any vulnerability of the system under design. The candidate will work with and extend a ChipWhisperer board (https://newae.com/tools/chipwhisperer/) and its software. Check out the above link to know more!

Blockchain è la tecnologia dei Bitcoin, una tecnologia del futuro. Si tratta di un “libro mastro” per la registrazione di transazioni (non solo di denaro) distribuito e aperto a tutti, quasi impossibile da falsificare. Etherium, una delle possibili piattaforme blockchain, supporta anche l’esecuzione di piccoli script all’interno del blockchain, i cosiddetti contratti. L’obiettivo finale di questo argomento è quello di arrivare a definire un’approccio di composizione leggero per l’integrazione di contratti. Ma prima: Qual è il potere espressivo di questi contratti? Come sono fatti? Quali operazioni sono possibili? Quali sensate? Come possiamo mettere in comunicazione due contratti?

Non esistono strumenti che permettano a un utente non programmatore di sviluppare dei bot. Come possiamo invece mettere questo utente nelle condizioni di svilupparsi un bot tutto suo?

La data science è una disciplina emergente che combina tante aree della computer science — data management, machine learning, statistica, UI design — per creare valore dai dati, dati che continuano a crescere con ritmi esorbitanti (Big Data). Innumerevoli sono le sfide da affrontare, dalla gestione di grandi moli di dati, alla loro rappresentazione, interpretazione, analisi e visualizzazione. Altrettante sono le domande di ricerca che si possono studiare.
Rispondere a queste domande richiede il coordinamento di operazioni diverse (analisi di dati, formattazioni di dati, crawling del Web, …). Lo scopo di questo progetto quindi è quello di sviluppare un sistema di analisi dei dati basato sul concetto di Workflow/Business Process Management che permetta la modularizzazione delle operazioni e la loro orchestrazione a partire da un modello grafico.

Description:
The thesis is in the fields of data science, big data management and machine learning.
The goal of the thesis is to investigate how, given a large set of experimental data and a set of existing models which should approximate them, it is possible to automatically evaluate the performance of the models.
Techniques to compare a single experiment to a single model already exist. The research question is about exploiting the large amount of experimental data which are nowadays available, all together, to better assess and characterize the performance of models. This assessment could also drive further model improvements.
The context is provided by the domain of combustion kinetic modelling (chemical engineering field), where models are continuously developed and must be tested and improved on real data. However, the same techniques investigated in this thesis could also be applied to many other fields. No knowledge in chemical engineering is required.

After about 20 years of development, MEMS accelerometers based on standard capacitive topologies are reaching their ultimate performance, with a major factor, limiting new applications (IoT, navigation, augmented reality), given by offset drifts.
To overcome this limit, new working principle should be investigated. This Thesis proposes a new concept based on the modulation of the inertia in a rotational MEMS accelerometer, to filter offset drifts.
The work includes the MEMS structure development, the conception and development of electronic blocks, and a thourough experimental campaign using shakers and temperature chambers to verify the accelerometer performance.

MEMS gyroscopes are heavily entering the automotive market. The increasing demand of robustness and performance is now claiming for structures that are immune to effects of vibrations that typically affect a vehicle. This thesis develops around new amplitude-modulated MEMS gyroscopes based on levered sense modes for improved rejection of linear vibrations, and in particular aims at modelling and validating the combined effects of quadrature error and vibrations on the performance of MEMS gyrosocpes.
Suitable structures will be developed and tested under combined rotations and vibrations. Electronics will be developed to cancel quadrature either with electromechanical compensation or with direct electronic cancellation. A comparison of the different quadrature cancellation techniques against vibrations will be the final achievement of the Thesis.
