Tecniche integrate per l'identificazione dinamica di murature storiche: interferometria radar, accelerometri e Deep Learning

La conservazione delle infrastrutture storiche in muratura rappresenta una sfida complessa per l'ingegneria civile, resa ancora più urgente dalla crescente consapevolezza della vulnerabilità sismica di tali opere, drammaticamente evidenziata dagli eventi sismici degli ultimi decenni (Irpinia 1980, Assisi 1997, L'Aquila 2009, Emilia 2012, Amatrice 2016). Ponti, acquedotti, torri e edifici religiosi non sono soltanto testimonianze tangibili del patrimonio culturale, ma spesso assolvono anc...

Development of alumina-reinforced elastomeric composites via additive manufacturing

Vat photopolymerization (VPP) enables the fabrication of high-resolution elastomeric components with complex geometries and excellent surface quality. However, the relatively low mechanical strength and durability of commercially available elastomeric resins limit their broader structural and functional applications. Enhancing mechanical performance while preserving the inherent deformability of elastomeric materials remains a significant challenge, particularly in particle-reinforced systems...

Distributed control of multi-agent systems: formation strategies and consensus in networked applications

This thesis focuses on two important problems in the area of Multi-Agent Systems (MAS) and distributed control: the coordination of drone swarms for area coverage and video acquisition, and the consensus-based management of backup batteries in DC islanded grids. Both problems are studied with the aim of developing control strategies that are scalable, adaptive, and suitable for real-world applications, respecting specific constraints. In the first part of the thesis, a leader–follower fram...

Hyperparameter optimization of deep learning models using high-performance computing resources

This thesis focuses on the hyperparameter optimization of deep-learning models using high-performance computing (HPC) resources, in order to study cluster counting in drift chambers. Cluster counting is a promising particle-identification technique in particle- physics experiments, where the goal is to reconstruct the number of primary ionization clusters from digitized waveforms. To support this study, realistic simulated samples are first generated using a Garfield based simulation pac...

Caratterizzazione dell’effetto acustoelastico nei materiali mediante un nuovo metodo teorico e sperimentale di tipo goniometrico

La presente tesi si inserisce nell'ampio scenario della ricerca scientifica dedicata allo studio dell'effetto acustoelastico nei solidi, fenomeno che descrive l'influenza dello stato di sforzo sulle proprietà meccaniche e sulla propagazione delle onde ultrasoniche nei materiali. L'obiettivo principale del lavoro è stato lo sviluppo di un metodo teorico e sperimentale per la caratterizzazione quantitativa dei moduli di II ordine (SOEC) e III ordine (TOEC) nella configurazione naturale, basato ...

Innovative adsorbent materials for reactive capping of contaminated marine sediments

The development of anthropogenic coastal activities has led to the contamination of marine sediments with hazardous substances, posing serious risks to the health and well-being of humans and the environment. It is of paramount importance to develop sustainable technologies for the simultaneous treatment of different contaminants, providing a permanent solution to reduce the hazardousness of sediments in aquatic environments. Recently, nanomaterials are gaining ground in the remediation sec...

Robust and secure semantic communication methods over integrated terrestrial and non-terrestrial networks

The integration of Terrestrial Networks (TNs) and Non-Terrestrial Networks (NTNs) is expected to play a central role in future Sixth Generation (6G) systems by providing seamless connectivity across ground, air, and space segments. This evolution supports applications such as remote sensing and disaster management, which require the reliable transmission of large volumes of data under stringent bandwidth, latency, and energy constraints. However, this trend exposes communication systems to ad...
