Design and Simulation of Fast Discharge Units (FDUs) for Toroidal Field Coils of Divertor Tokamak Test (DTT)

2023

Questa tesi riassume il lavoro svolto durante il triennio di dottorato nel periodo compreso tra il 2019 e il 2022. Come è ben noto nella comunità scientifica, l'ambiziosissimo progetto di fusione nucleare ha richiesto e richiede notevoli risorse ed investimenti; La tabella di marcia per la generazione di energia da fusione nucleare su larga scala comprende missioni impegnative. I progetti ITER e DEMO, essendo progetti internazionali, richiedono la collaborazione (sia dal punto di vista economico che tecnico) di diversi Paesi a livello europeo ed extraeuropeo; per questo motivo i vari aspetti tecnologici, che verranno poi implementati e applicati nei reattori a fusione finali, vengono prima …

A simulation study for assessing the impact of energy storage systems for Fast Reserve with additional synthetic inertia control on the Continental E…

2022

This article shows the results of a simulation study on the application of battery storage systems for providing fast frequency regulation (the so-named Fast Reserve) with additional synthetic inertia control. The aim of the study is to assess the impact of the extension of the regulation provided by the FRUs to all the Continental Europe synchronous grid, with the same power proportions of the first Italian FRU auction. The simulations are conducted in two different scenarios: a base one related to 2020 and a future one related to 2040 and based on ENTSO-E projections for load and generation. The results show that, for the reference incident of 3000 MW, the frequency quality parameters in …

Wideband THz time domain spectroscopy set-up based on ultrafast pulsed laser: model and experiments

2014

We present an analytical model describing the full electromagnetic propagation in a THz Time Domain Spectroscopy (THz-TDS) laser based system. We pay particular attention to the modelling of the time-frequency behavior of all the stages, which compose our experimental set-up. In particular, our model takes into account the following features: pump beam focusing into the generation crystal; phase-matching between pump and THz pulses inside both the generation and detection crystals; chromatic dispersion and absorption inside the materials; Fabry-Perot effect in both the crystals; diffraction along the propagation, focalization and overlapping between THz and probe beams; Electro-Optic Sampli…

Simulated Annealing Technique for Fast Learning of SOM Networks

2011

The Self-Organizing Map (SOM) is a popular unsupervised neural network able to provide effective clustering and data visualization for multidimensional input datasets. In this paper, we present an application of the simulated annealing procedure to the SOM learning algorithm with the aim to obtain a fast learning and better performances in terms of quantization error. The proposed learning algorithm is called Fast Learning Self-Organized Map, and it does not affect the easiness of the basic learning algorithm of the standard SOM. The proposed learning algorithm also improves the quality of resulting maps by providing better clustering quality and topology preservation of input multi-dimensi…

Deep learning techniques for visual object tracking

2023

Visual object tracking plays a crucial role in various vision systems, including biometric analysis, medical imaging, smart traffic systems, and video surveillance. Despite notable advancements in visual object tracking over the past few decades, many tracking algorithms still face challenges due to factors like illumination changes, deformation, and scale variations. This thesis is divided into three parts. The first part introduces the visual object tracking problem and discusses the traditional approaches that have been used to study it. We then propose a novel method called Tracking by Iterative Multi-Refinements, which addresses the issue of locating the target by redefining the search…

Rules and norms: two kinds of normative behaviour:

2016

Celano’s notion of a “pre-convention” is grounded in the opposition between two allegedly different kinds of normative behaviour: observing a “rule” and conforming to a “norm”. This opposition plays a central role in Celano’s paper, and marks a crucial point in his intellectual trajectory. Nevertheless, it remains largely implicit. In this paper, I try to make it fully explicit, giving a more precise characterisation of both kinds of normative behaviour. I also focus on the importance of distinguishing between them, express some conjectures (or wishes) regarding Celano’s future research, and propose a (marginal) criticism.

Fentanyl and sufentanyl in fast track anaesthesia for major intra-abdominal surgery

2012

Background and aim: Major intra-abdominal surgery is estimated to have high costs annually in Italy. In an attempt to decrease surgery costs and improve outcome for patients, fast-track programs have become popular. This is especially due both to the improvement of surgery and to the new anesthetic agents (regarding pharmacokinetic and pharmacodynamic) resulting in better care for patients. The aim of this study was to evaluate two different anesthetic protocols in patients undergoing scheduled anesthesia including the combination of two different opioids (fentanyl or sufentanil) with the same hypnotic and muscle relaxant. Material and Methods: 40 patients, with an American Society of Anest…
