Descrizione:
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!

Simone Formentin, Federico BianchiDescrizione
Descrizione:
Nowadays, wheeled vehicles are equipped with many driver assistant systems - such as the ABS (anti-lock break system) or the TCS (traction control system) - which increase driver and passengers safety and comfort. While these systems have become a standard on all four-wheeled vehicles, their use on two-wheeled vehicles is more recent (the ABS became mandatory in the EU only in 2016). Therefore, in the field of two-wheeled vehicles, the interest in electronic systems for the control of vehicle dynamics is still recent. Particularly interesting and challenging, is the attitude estimation since it plays a major role in the overall vehicle dynamics. In this regard, a reliable method should take into account also the multi-mode nature of the controlled system: the overall dynamics can be considered as a collection of several continuous dynamics representing different operational modes - acceleration, braking, steering - indexed by a discrete variable. The goal of this thesis is the investigation and development of methods for motorcycle attitude estimation.

Adaptive Kalman filtering for hybrid systemsPersona da contattare:
LUIGI PIRODDIEmail:
luigi.piroddi@polimi.it Corso di studio in Ingegneria dell'Automazione
Altri membri del gruppo di ricerca:
Simone Formentin, Federico BianchiDescrizione
Descrizione:
The filtering problem consists in reconstructing or estimating a non-measurable variable (called remote variable) based on the knowledge of other, measurable and uncertain variables. This uncertainty refers to measurement noise related to sensors, and to process noise which accounts for all those modelling aspects that for various reasons are not taken into account. In Kalman filtering, the noise is expressed by means of stochastic Gaussian processes described in terms of their statistical properties (mean and covariance). The filter formulation requires the knowledge of a model of the underlying system, as well the process and measurement noise covariance matrices. In practice, the latter are design parameters, whose setting critically affects the filter performance.
This is all the more true for hybrid systems, whose behavior can be described by the interaction of several time-driven continuous dynamics (continuous states or modes) indexed by event-driven discrete dynamic (discrete states). Indeed, in that framework also the noise covariances change with the discrete state.
The problem of estimating the covariance matrices that optimize the filter performance is an open problem in literature, which could have a significant impact on Kalman filter-based applications. The goal of this thesis is the investigation of the filtering problem in the context of hybrid systems, with particular emphasis on the adaptation of the covariance matrices involved in the filter computations.

Dr. Federico BianchiDescrizione
Descrizione:
Hybrid systems are heterogeneous dynamical systems whose behavior can be described by the interaction of several time-driven continuous dynamics (continuous states or modes) indexed by event-driven discrete dynamic (discrete states). They can represent technological systems where continuous models such as differential or difference equations describe the physical and mechanical part, and discrete models such as finite-state machines or Petri nets describe the software and logical behavior. For example, while driving, a car follows different dynamics, depending on the specific phase (acceleration/braking, cornering) or the track characteristics (slope, road surface, weather conditions).
The goal of this thesis is the development of a randomized black-box technique to identify both the system modes and the switching mechanism directly from data.

Matteo, Matteucci, Marcello Restelli, Luca FerrariniDescrizione
Descrizione:
Sticking occurs when the drillstring cannot be moved (rotated or reciprocated) along the axis of the wellbore. During drilling operations, a pipe is considered stuck if it cannot be freed from the hole without damaging the pipe, and without exceeding the drilling rig's maximum allowed hook load. Stuck-pipes are one of the main causes of NPT (Non-Productive Time) in drilling operations and are estimated to cost between 200 and 500 millions of dollars each year to the oil industry. Various sensor measurements taken throughout the drilling process are available in a large dataset to be used to tune the models.
This thesis proposal falls within an ongoing collaboration with ENI on Big data analytics for NPT prediction and operational efficiency.

Descrizione:
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.
