Development of a multiscale 1D-0D cardiovascular model to investigate orthostatic stress responses

The study of orthostatic stress effects on the cardiovascular system has gained significant attention since the 1960s, initially driven by the space race, and more recently by advances in medicine and technology. The full extent of the physiological responses to orthostatic stress still remains not fully understood, owing to the complex interplay between multiple body systems and external factors that influence cardiovascular function. To address this complexity, increasingly sophisticated co...

Task and Motion Planning in Neuro-Symbolic Robotics: From Individual Agents to Multi-Agent Systems

Autonomous robotic systems operating in continuous and highly dynamic environments require reliable and consistent decision-making over long horizons. To address these challenges, this thesis develops hierarchical decision-making frameworks that decompose complex planning problems into multiple layers of abstraction, spanning from high-level task reasoning to low-level motion control. Such hierarchical structures enhance scalability, interpretability, and modularity, enabling robust reasoning...

Multi-wavelength and multi-messenger observation of blazars' jets

Relativistic jets in Active Galactic Nuclei (AGN) are among the most powerful sources of radiation in the Universe. The radiation spans the entire electromagnetic spectrum, from radio wavelengths to $\gamma$-rays. Active Galactic Nuclei are divided into different categories, and the one this thesis will focus on is blazars. Blazars are radio-loud galaxies whose jet is aligned with the line of sight. Hence, the observed emission is strongly beamed and amplified due to relativistic Doppler effe...

Essays in Banking and Systemic Risk

This dissertation is a collection of three papers on banking and systemic risk. The first chapter develops a multi-objective optimization framework for banks’ securities portfolios, considering both individual and systemic risk. The findings show that while diversification can reduce individual risk, including systemic risk in the objective function leads to more concentrated portfolio allocations. The second chapter empirically investigates the sovereign-bank nexus in the Euro Area from a ma...

FRAMEWORK FOR CUBESATS MISSION MANAGEMENT, DESIGN, AND OPTIMIZATION

This doctoral work proposes a practical framework for the design and management of CubeSat missions. In recent years, CubeSats have moved from their original intent of educational nanosatellites to platforms that can deliver high scientific and commercial value. This mission performance improvement comes with a rise in their complexity. Yet, most CubeSat teams remain small, with limited experience and constrained budgets. The goal of this work is to streamline the way such missions are design...

The Active Phases of a Galaxy in the JWST and Euclid Era: From Radio Jets and Multiphase Outflows to Mergers

The objective of this thesis is to study the key processes that regulate the growth and evolution of galaxies, focusing on the role of active galactic nuclei (AGNs). AGN feedback, in the form of energy flows and radio jets, is a fundamental mechanism that regulates star formation, redistributes gas and dust, and shapes the structure of the host galaxy. Another phenomenon that affects galactic evolution is galaxy mergers, as these provide fresh gas, triggering starbursts and fueling black hole...

La Politica di Walter Benjamin: una metafisica materialistica del Profano

La ricerca dottorale tematizza il pensiero filosofico-politico di Walter Benjamin che affiora dalla Politik: un’opera frammentaria e mai terminata, cui il filosofo lavorò a cavallo degli anni Venti e nelle cui categorie e argomentazioni principali il presente lavoro rintraccia l’esito di un processo di elaborazione teorica avviato almeno una decina di anni prima, nonché il marchio che contrassegnerà la sua speculazione matura. A fondamento della ricerca si colloca, innanzitutto, l’interesse p...

Manufatti architettonici e scultorei per l’ostensione delle reliquie in Europa tra XII e XVI secolo: pulpiti, cibori, tribune.

This research work focuses on the history and development of architectural and sculptural structures built specifically for the display of relics (tabernacles, ciboria, tribunes, external pulpits) in Europe, and more specifically in Italy, between the 12th and 16th centuries. The first chapter of the thesis analyses, through written sources from late antiquity to the early modern age, the use of liturgical structures designed for other purposes (in particular the altar and the pulpit) as a ...
