Energy substitution by sector: technological flexibility and the impact of mitigation policy

The impact of mitigation policies on economic activities is a longstanding controversial issue justifying the large strand of literature analysing the effect of climate change policies in terms of environmental and economic costs. From the Kyoto Protocol to the current climate policy agenda approved by the European Union (EU) in October 2014, mitigation of climate change still constitutes a challenging long term objective at the global level, and it is particularly relevant for the EU. Beside...

Integrated reporting : insights, critical issues and future research agenda

The main objective of this thesis is to understand Integrated Reporting (IR) in action. Given that IR is a relatively recent phenomenon, insights are needed to understand how it works in practice and, as a consequence, if it could eventually become the corporate reporting norm, as the International Integrated Reporting Council (IIRC) advocates. To this end, I discuss the background of how IR has been developing. I then offer an in-depth presentation of the emerging IR literature using a Struc...

Associated production of the Higgs boson with a W boson in proton-proton collisions : an explorative analysis of the three-leptons final state with the ATLAS experiment

This work concerns the study of the properties of the recently discovered Higgs boson in proton-proton collisions at the Large Hadron Collider (LHC). The Higgs boson is the particle that, according to the Standard Model (SM) theory, is responsible for the mass of all the known elementary particles (fermions and bosons). Its existence was postulated during the '60s in the so-called Brout- Englert-Higgs mechanism (BEH), but to have the experimental evidence of this particle scientists had to wa...

Power generating unit for the future more electric aircraft : power electronic converter modelling and design

This thesis deals with the performance assessment of different permanent magnet motor drives topologies for Starter/Generator systems in aircraft applications. The comparison will focus on power electronics topologies, evaluating, by means of simulations performed with Matlab/Simulink and Plexim Plecs, some relevant key points such as efficiency, losses and motor current harmonic distortion. For all the topologies, simulations will be carried out considering both 2-Levels and 3- Levels conver...

I servizi pubblici tra liberalizzazione del mercato e tutela dell'utenza: il contratto di servizio

Questo lavoro di ricerca si impernia sul tema della disciplina dei servizi pubblici, con specifico riguardo al settore delle comunicazioni elettroniche e dell'audiovisivo, relativamente al quale, per la prima volta, si ਠconiata l'espressione †œservizio universale†�1. Nell'esposizione si ਠritenuto pi๠efficace seguire una struttura a †œpiramide rovesciata†�: per arrivare a trattare in modo completo e comprensibile i temi del servizio pubblico, del contratto di servizio e del servizio univ...
