Talking about Migration: the Online Discourse of Some Italian Political Party Leaders
2020
The aims of the article are to deconstruct the frames of migration crisis embedded on the official web sites, social networks and blogs belonging to the leaders of the main Italian political parties, positioned on different points of the left or right political spectrum, in the period 2015-2016. According to the relevance of the Italian context, we are also going to study the position of a party that can be considered a post-ideological movement that represents itself as outside of a traditional political spectrum: the Five-star Movement. We analysed text, images and videos published on the Internet 2.0 sites in order to show the legacy of colonialism that was characterized by the ambivalen…
An interface protection system based on an embedded metrology system platform
2021
Abstract The aim of this work is to present an interface protection system (IPS) for Distributed Generators (DG) and Energy Storage Systems (ESS). The new prototype of IPS guarantees standard protection requirements, in terms of both voltage and frequency measurement accuracies and trip times. Moreover, it has the additional functionalities of implementing a communication link between the Distribution System Operator (DSO) and the DG and ESS Inverter. The new IPS is based on a smart meter platform with an integrated power line communication modem. Moreover, it has also an integrated metrology section. Experimental tests will show how this last feature allows a significant reduction of the m…
On the conversation between female videobloggers and commentators
2021
El desarrollo de YouTube como una plataforma social surge a partir de dos ideas. En primer lugar, los amateurs pueden producir contenido de cualquier índole. Y, en segundo lugar, su audiencia puede expresar su opinión sin restricciones. Este intercambio de información impulsa la formación de comunidades en torno a un interés común: contenido y/o videobloguero. La dimensión social en YouTube tiene lugar de manera bidireccional. La interacción regular entre las dos partes ha significado un cambio crucial en la percepción de la producción y consumo audiovisual, así como también en los productores de vídeo, amateurs y audiencia. Las investigaciones iniciales se han dirigido a examinar los comen…
A PLC based monitoring and remote control architecture for Distributed Generation and Storage systems in LV smart grids
2021
(Abstract) This paper proposes a new power line communication (PLC) architecture for monitoring and remote control of Distributed Generators (DG) and Energy Storage Systems (ESS) connected to low voltage distribution networks. The final aim is to improve the performance of the PLC link in terms of robustness and efficiency in devices addressing. The proposed solution is based on a concentrator, to be installed in secondary substation, and a new PLC bridge, to be linked both to inverters and interface protection systems of DGs or ESSs. In this way, a communication link is obtained between distribution system operator (DSO) and DG or ESS owners. The proposed system is able to provide advanced…
Implementation of a PLC Field Analyzer on a G3 Modem Platform
2021
Nowadays, power line communications (PLC) are a widely used technology in distribution grids, both for automatic meter reading and automation applications. PLC performances (in terms of capacity, coverage, robustness, and data transmission rate) can be significantly affected by electrical network topologies, connected loads and disturbances. Thus, utilities and modem manufacturers are increasing their interest in electrical network characterization. In this framework, a software tool is proposed in this paper to measure received signal and noise levels. As case study, it is implemented on a G3 PLC transceiver, widely used for smart metering purposes. In this way, a PLC channel characterizat…
Science, Its Publics and New Media. Reflecting on the Present and Future of Science Communication.
2013
Scientific journalism faces the challenge to adapt not only to new formats but also to new information exchange dynamics. New online platforms, making it easier to access and produce scientific content, are forcing science publics to evolve. The online environment has turned into science communication reality, and both scientists and communicators must adapt to it. This paper discusses these changes and their implications for science journalism and an informed citizenry.
Experimental Evaluation on Narrow Band Power Line Communication in Medium and Low Voltage Smart Grids
2013
The aim of this work is to perform a feasibility study on the power line communication for the development of a new generation of interface devices (IDs) for smart grid and energy storage applications. More in detail, this paper deals with one of the most important issues on this topic, which is the communication system. Among the existing communication technologies, the study is focused on power line communications (PLCs). After an analysis of the state of the art in the field, the main aspects are analyzed, concerning the open issues on the use of PLCs, especially for medium voltage (MV) and low voltage (LV) systems. In this work the use of PLC in MV-LV networks is investigated, by means …
Rakstveida sarunu iezīmes tiešsaistes diskusiju forumos
2017
Pastāv dažādas komunikācijas formas un viena no tām ir digitālā komunikācija. Ziņu sūtīšana un saņemšana notiek digitālā vidē, kur valda īpaši noteikumi, nerakstīti likumi, kur valodas stila pielietojums atšķiras gan funkcionāli, gan pēc tipiskā satura. Digitālā valoda tiek identificēta kā “rakstveida saruna”, jo tā balstās, izmantojot rakstu kodu un sarunvalodas dinamiskās īpašības. Sociālajos forumos ziņu apmaiņa noris caur t.s. diskusiju pavedieniem, kas dod iespēju parādīt dalībnieku iejaukšanos pēc tā veida, kas tiek izteikta un mērīta kā reakcija vienam uz otru. Šī pētījuma mērķis ir noskaidrot, kāda veida iejaukšanās dominē diskusiju forumos tīmekļa vietnē “Doctissimo.fr”? Darba auto…
DEVELOPMENT AND CHARACTERIZATION OF ADVANCED METERING AND ICT SOLUTIONS FOR SMART ENERGY DISTRICTS
2022
Climate change will have an influence on the world's 8 billion inhabitants, the majority of whom live in cities, which account for roughly two-thirds of the CO2 emissions that are at the root of the climate crisis. To attain a net-zero carbon future, a rapid transition across business models and policy is required. At the same time, policy and legislation are struggling to keep up with smart technology and the Internet of Things. The management of smart urban infrastructure is the key to successful decarbonisation and the achievement of sustainable cities. In this framework, the smart electricity infrastructure shall be equipped with integrated technologies, such solar panels, storage facil…
