Rapporto su Standard ICT per le Smart Energy Grid
No full textIn questo report vengono esaminate un ampio numero di iniziative di standardizzazione nell'ottica dell'interoperabilità per le smart grid. L'elenco dei progetti e degli standard non intende essere esaustiva ma piuttosto vuol dare un'idea di dove e come gli standard ICT si rendono necessari per la comunicazione nel contesto delle smart grid e di come, a livello internazionale, ci si sta muovendo e con quali risultati. Dopo un inquadramento (Cap.1) delle tipologie di iniziative che vengono esposte e di come si collocano nella rete di telecomunicazione che si va sovrapponendo a quella elettrica (Cap. 2), si analizzano una serie di Reference Model che inquadrano il problema in una vista generale (Cap 3 PI). Si passa quindi all'esame di una serie di standard per il mercato elettrico (Cap 3 PII), per l'automazione della rete elettrica (Cap 3 PIII) e si accenna a uno per l'integrazione, nella rete, della generazione distribuita (Cap 3 PIV). Vengono poi esaminati alcuni standard per i sistemi di controllo degli edifici, che, in particolare si applicano al controllo energetico (Cap 3 PV). Si accenna, infine, ad alcuni standard per l'eCommerce dei prodotti petroliferi o del gas (Cap 3 PVI.) Nelle tre appendici si trova infine una bibliografia per approfondire I vari argomenti trattati (App. A), un elenco degli enti impegnati nelle varie iniziative di standardizzazione (App. B) e una tabella ch

An approach to provide shared architectural principles for interoperable smart cities
No full textSmart City projects are moving from trials to complete Smart City realizations. Smart Cities must work as complex ecosystems of interoperable and composable services yet there is currently a proliferation of less than interoperable and portable vertical services. To diminish the barriers among these silos different approaches have been attempted but no single one of them has garnered general acceptance and adoption. The international initiative Internet of Things Enabled Smart City Framework (IES-City) convenes a broad set of stakeholders to build a consensus foundation of architectural principles for interoperable Smart Cities. IES-City evaluates global existing frameworks, tools and applications to distil a common set of Pivotal Points of Interoperability (PPI). PPI have the potential to enable both interoperability and suitable variation and reduce barriers to composable Smart City deployments. The IES-City concept is that such PPI exist in practice and need only be discovered. This paper describes the IES-City methodology. © Springer International Publishing AG 2017
Looking for the unified classification and evaluation approach of SG interface standards for the purposes of ELECTRA IRP
No full textA huge set of Smart Grid related standards already exist and is continuously being updated in various technical working groups in various parts of the world. Ongoing EU-funded ELECTRA Integrated Research Programme (IRP) on Smart Grids [1] aims to re-use the existing standards within its in progress activities considering to be in compliance with the standardization groups like CEN/CENELEC/ETSI, NIST and others. Moving towards the implementation of the functional architecture, it is important to be aware of the information to be exchanged and how communication protocols can be used in support of Smart Grid information exchange. Therefore, a reference method needs to be developed for assessing and classifying the ICT interoperability standards and specifications. The existing Common Assessment Method for Standards and Specifications (CAMSS) is thought to be a tool for Public Administration choices of standards, especially for e-government and e-procurement in EU. Despite CAMSS defines an evaluation schema for standards and specifications via an Excel tool, this paper shows that the CAMSS approach needs to be modified and adapted for the goals of ELECTRA IRP. Moreover, the elaborated tool would not only be useful for ELECTRA purposes but it would be used in a broader Smart Grid (SG) perspective as well and also, with some slight adaptations, more in general, for all complex contexts involving a high number of standards (e.g. the Smart City context). © 2015 IEEE
Supporting software interoperability using standardised interfaces: Issues and needs
No full textThis paper reports the experience, gained in two different European research projects, TexWIN and ARTISAN, in connecting software prototypes with pre-existing enterprise software like ERP and Scheduler. The two systems aim to support human in optimizing the production processes, but their functioning clearly depends also on the collaboration with external software systems; this collaboration is needed for production data collection and the interfacing with enterprise machine control systems. Activities in the projects regarded the analysis and design of a communication system for the data exchange with the enterprise software: various possibilities and existing standards were considered and the feasibility of their adoption established but, despite the declared project objectives, the standard based interfaces were not implemented. The aim of this paper is to describe both the followed approach to introduce standards in the research project activities and to propose a first analysis of the reasons for the missing concrete adoption of standardized interfaces.

Predicting the impact of public events and mobility in Smart Cities
Full text linkThe ubiquitous presence of smartphones and the ever-expanding Internet of Things are generating a treasure trove of data on human movement. We harness the power of Artificial Intelligence to extract knowledge within this data, in particular for predicting people flows and density in a Smart City. This predictive ability holds immense potential for a multitude of applications, from optimising people flow to streamlining event planning, while offering a powerful tool for pre-emptive identification of situations that may lead to crowd disasters. In this paper, we tackle two crucial aspects of people mobility using data from public events and an Italian mobile phone network: to predict both event attendance and future crowd density in specific areas. The event details (location, time etc.) are automatically gathered and stored in a structured format. Next, we handle these problems are treated in a “supervised learning” setting, and various state-of-art Machine Learning techniques are tested to find the best model for each task. The obtained models will be encapsulated into a Policy Support System contributing to foster planning actions of mobility services
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
