Amorphous silicon nanotubes
2017
In the following, the attention will be focused on the silicon nanotube (SiNTs) that is a highly desired form of silicon for its fundamental role in the miniaturization trend of the electronic devices. After a description of the properties and applications of SiNTs and their fabrication methods, the attention will be focused on chemical vapour deposition (CVD) template synthesis that is the most usual synthetic method for this material. Then, galvanic template synthesis will be described as a general method for the fabrication of different metals and oxides nanostructures, therefore the use of this technique for synthesizing SiNTs will be detailed. Characterization methods will be also desc…

La traducció automàtica en la pràctica: aplicacions, dificultats i estratègies de desenvolupament
2014
En aquest article es descriuen els sistemes de traducció automàtica, les seves aplicacions actuals i les principals dificultats que ha d’afrontar aquesta tecnologia lingüística. Es presenta el sistema Apertium, una plataforma de traducció automàtica de codi obert sobre la qual s’han construït diversos traductors automàtics entre diferents parells d’idiomes, en els quals està inclòs el català. Basant-se en l’experiència dels autors, es descriuen algunes tensions que es donen en el desenvolupament de les dades lingüístiques d’un traductor automàtic i les solucions de compromís a què cal arribar per a construir sistemes útils.
Contributo al dimensionamento di una briglia a fessura con profilo lineare doppio
2011
L’obiettivo della sistemazione idraulica del tratto montano di un corso d’acqua e assicurare una condizione di stabilita per il cavo fluviale, mediante il raggiungimento di una condizione di equilibrio permanente tra la portata solida e quella liquida (Benini, 1984), facendo ricorso ad interventi di tipo strutturale capaci, nel rispetto della vigente normativa in tema di tutela ambientale, di conservare e preservare gli ecosistemi preesistenti a valle (Ferro, 2006, 2008).
Paramedia : thresholds of the social text
2017
This work is an adaptation of Gerard Genette’s theory of paratexts to social media. Paratexts are information surrounding texts, and usually helping the user to decide whether or not to consume a text. In social media, a plurality of new information surrounds texts we read every day. They are dynamic by nature and have different authors: the social platforms, like Facebook or YouTube; the authors of texts, and the users who comment and share them. This collection of four articles will debate the ethos in social media, what is an author in social media, what are the identified paratexts in selected social media websites and the limits of interpretation of paratexts in contemporary Brazilian …
One-loop corrections to light cone wave functions: the dipole picture DIS cross section
2018
We develop methods needed to perform loop calculations in light cone perturbation theory using a helicity basis, refining the method introduced in our earlier work. In particular this includes implementing a consistent way to contract the four-dimensional tensor structures from the helicity vectors with d-dimensional tensors arising from loop integrals, in a way that can be fully automatized. We demonstrate this explicitly by calculating the one-loop correction to the virtual photon to quark-antiquark dipole light cone wave function. This allows us to calculate the deep inelastic scattering cross section in the dipole formalism to next-to-leading order accuracy. Our results, obtained using …
