La quotazione nel mercato Euronext Growth Milan come obiettivo strategico delle PMI italiane

In recent years, the capital market for SMEs has been at the center of strong interest from market operators, the academic world and institutions. The objective of this thesis is to analyze the peculiar aspects of the stock market dedicated to small and medium-sized enterprises and the real advantages deriving from listing. In addition to the financial aspects, the company that decides to go public benefits from: greater visibility, increased reputation and standing, ability to attract talent...

Turismo sportivo outdoor: un caso studio

The research project, with a multidisciplinary approach, analyses the determinants of the experiential tourism sector, with particular interest in outdoor sports tourism, by profiling and studying the distinctive characteristics of consumers. To this end, the project develops both a theoretical-interpretative model of the demand for experiential tourism and an empirical investigation aimed at its validation by means of descriptive statistical analysis. The data collected through the administ...

Characterization of airborne and respiratory particles in indoor environments

The understanding of the relationship between human health and indoor air quality (IAQ) is a never-ending challenge. For decades the main design parameters of efficient buildings were the energy efficiency and, in case, the protection from outdoor pollutants whereas the possible health treat of indoor sources was mostly underestimated. In fact, building occupants are not properly aware of the indoor air quality, of their exposure to pollutants or pathogens and, consequently, of how much they ...

Prediction of failure under different stress states and loading conditions for shear-sensitive materials

Anticipating materials’ fracture in different operative scenarios is fundamental for a safe and robust design. This doctoral thesis is focused on investigating the fracture response of the aerospace aluminum alloy Al2024-T351, and it aims to propose a material model able to capture its behavior comprehensively. An extensive experimental campaign has been conducted to probe material failure under various loading conditions, from shear-dominant loadings to high stress triaxiality governed state...

Design methodologies of modular active equalization circuits for lithium-ion battery packs

This dissertation deals with the maximization of the usable capacity of lithium-ion battery packs which present imbalances. The original contribute proposed regards the development of model-based design methodology for active balancing systems, which also include parasitic effects and control nonlinearities. In particular, two different active balancing circuits have been detailed analyzed. Through a multi-winding transformer architecture, a cells-to-cells self-balancing energy tranfer proce...
