Riflessioni su pandemia e comunicazione politica: l’interesse online per leader e partiti
2021
Has the pandemic reversed trends already taking place in contemporary politics or has it reinforced ongoing political phenomena? The serious health risk posed by the spread of Covid-19 has in fact legitimised dynamics that more or less silently had long been spreading, including the personalisation of politics, the (alleged) disintermediation of communication, different populist styles, the danger of authoritarian drifts. The challenges to democracy identified by the political literature, as the pandemic spreads, are enriched by new elements. Trust in national institutions, which has been years marked by a negative trend, in countertendency has increased during the peak of the epidemic. new…
The Web Participatory Environment: a New Genre in Health Exchange
2014
The Internet has provided new and expanded means of communication, incorporating all forms of discourse and registers, including that of medical discussion. Certain sites, in fact, specialise in healthcare and provide information, offering direct access to counsellors (medical professionals qualified to provide advice) and forums in which the role of participants is that of potential nonspecialists who share opinions, gather information on healthrelated issues and ambiguous medical meanings. The benefits of a healthrelated online forum lie in its ability to quickly and conveniently connect people to both important information and to other people with knowledge regarding a specific health…
Les modalités linguistiques du commentaire sur internet comme prise de position ("stance-taking"): l'exemple des commentaires sur YouTube
2015
International audience; Sur Internet, le commentaire est par essence un lieu argumentatif. Réagir à un article, une vidéo, une image ou à n’importe quelle prise de parole, est l’occasion pour l’utilisateur du Web 2.0 de donner son opinion, de contredire, confirmer, infirmer, interpeller, dénoncer, c’est-à-dire dans tous les cas prendre position. En effet, comme l’écrivent David Barton et Carmen Lee dans Language Online : Investigating Digital Texts and Practices, commenter est un acte qui consiste à se positionner et positionner les autres, c’est-à-dire une véritable prise de position (« Commenting is an important act of positioning oneself and others, that is stance-taking », Barton et Lee…
Engineering victory and defeat: the role of social bots on Twitter during the French PresidentialElections
2018
International audience; The electoral campaigns of both Trump and Macron took place in a climate marked by accusations of “fake news”, manipulation of social media and personal attacks. Previous research has even shown that the same automated Twitter accounts were used to spread rumours to discredit both Hillary Clinton and later Emmanuel Macron, notably during the “Macron Leaks” scandal (Ferrara, 2017), which has led to accusations of orchestrated foreign infiltration in at least the French presidential campaign. Although it is difficult to distinguish (legitimate) foreign discussions of (rumours related to) French presidential candidates on Twitter on the one hand and intentional meddling…

Coupling circuit for power line communications
2013
A coupling interface couples a transceiver to one or more capacitive voltage dividers of a power transmission system. The coupling interface includes a first signal path including an adjustable inductance configured to form a resonance circuit with a capacitance associated with the one or more capacitive voltage dividers. The coupling interface may include a second signal path including an adjustable inductance configured to form a resonance circuit with the capacitance associated with the one or more capacitive voltage dividers.
An Innovative Coupling Solution for Power Line Communication in MV Electrical Networks
2019
One of the main problems in the diffusion of power line communication (PLC) in medium voltage (MV) networks is the need of a dedicated PLC coupler to be installed all over the network. To avoid this problem, the authors have studied, prototyped and patented an innovative PLC coupling solution which uses electrical elements embedded in most of the switchgears already installed in MV networks, i.e. the capacitive dividers of the voltage detecting systems (VDS). The new solution prototype is described in this paper, highlighting the advantages in terms of a significant reduction of both direct costs of equipment and infrastructures and indirect costs of installation and service interruption.

Model of line to shield power line communication system on a Medium Voltage network
2010
In this paper a complete model of a power line communication (PLC) system on a Medium Voltage (MV) network is presented in the case of a line-ground configuration. A simple and friendly Simulink (R) software is used to develop the model. A distributed parameter MV cable model in line-ground configuration is considered together with the power transformers, the signal coupling networks and the receiving and transmitting line coupling interface of a ST7540 FSK powerline transceiver. The performances of the complete PLC communication system are evaluated for different line lengths by means of the attenuation computed as ratio between the received and transmitted voltage signals.
