Modelling and design of origami-inspired deployable structures for aerospace applications

The increasing power demand of modern spacecraft requires solar arrays that are both lightweight and highly compactable. Origami-inspired deployable structures offer an effective solution, achieving large deployed areas within limited launch volumes. However, their strongly nonlinear folding behaviour poses significant challenges for numerical modelling: full finite element analyses are accurate but computationally expensive, limiting their use in early-stage design. This PhD research, conduc...

Security enhancement in islanded dc microgrids via flexibility resources

This doctoral dissertation presents the research conducted by the author during the three-year Ph.D. programme (XXXVIII cycle) in Electrical and Information Engineering at olitecnico di Bari. The primary objective was to design methodologies and control strategies for energy management in DC microgrids, with a particular focus on fostering the development of stand-alone modern microgrids that integrate significant shares of intermittent renewable resources. Another key aim was to enhance the ...

Quantum enabled wireless communication networks

Efficient resource allocation to enhance network performance for ultra-reliable and low-latency type communication (URLLC) is a major consideration since the development of the Inter- net of Things. Recent advancements, especially in Massive Machine Type Communication (mMTC), now demand goal-oriented data delivery. Coupled with those mentioned earlier, goal-oriented communication dictates a data-driven approach to meet the current demands. In addition to classical communication, quantum ...

Models and methods for eXplainable Artificial Intelligence in pervasive Cyber-Physical Systems

I sistemi cyber-fisici (CPS) integrano sensori, elaborazione dati, comunicazione e attuatori per monitorare e controllare i processi fisici in tempo reale attraverso dispositivi e protocolli Internet of Things (IoT). I modelli e i metodi di intelligenza artificiale (AI) sono sempre più integrati nei CPS per migliorare le capacità decisionali autonome basate sui dati. Nonostante i progressi nell'hardware, tuttavia, la maggior parte dei dispositivi opera ancora come strumento di misura passivo,...

Design and implementation of embedded subsystems for monitoring and managing vital parameters

This dissertation presents an interdisciplinary research pathway that integrates functional safety engineering, biosensing technologies, and eXplainable Artificial Intelligence (XAI) for embedded and resource-constrained systems. The common objective across these research lines is the development of intelligent and autonomous systems that are not only functional and efficient, but also interpretable, verifiable, explainable and safe. In the current landscape of pervasive computing and embedde...

Modeling and design of integrated optical spectrometers (IOS)

In this PhD work the topic of integrated optical spectrometers has been addressed, with a partic- ular focus on the miniaturization of optical spectrometers. In Chapter 1, a unified overview of the solutions reported in the literature was presented, organized both by operating principle (disper- sive, interferometric/FTS, and reconstructive spectrometers) and by technology platform (silicon photonics, hybrid approaches, reconfigurable materials). This framework was used to place the devi...

From structural mitigation to semantic completion: advancing recommender systems under data sparsity

In the modern digital ecosystem, Recommender Systems (RSs) play a crucial role by learning user preferences from historical interaction data to guide individuals through vast catalogs of content. Despite their widespread adoption, their effectiveness remains fundamentally constrained by the inherent problem of data sparsity. While Knowledge Graphs (KGs) have emerged as a powerful source for enriching sparse collaborative signals, existing approaches often process the entire KG uniform...

I solai a linee isostatiche di Pier Luigi Nervi e Aldo Arcangeli. Diagrammi di sforzi e forme costruite.

La ricerca indaga il rapporto tra forma architettonica ed efficienza strutturale, con particolare attenzione ai solai a linee isostatiche sviluppati dallo studio Nervi alla fine degli anni Quaranta. Queste strutture si fondano sulla teoria statica delle piastre, secondo cui l’eliminazione dei momenti torcenti lungo specifiche direttrici - le linee isostatiche - porta ad un’ottimizzazione del comportamento strutturale. L’osservazione della forte espressività formale di tali solai, in cui le ne...
