Electric and magnetic emission in near field region and thermal behaviour of power module for photovoltaic application
2015
The new power module, characterized by high power density, miniaturization of packages and layout and high frequency switching, are increasingly used in the field of in automotive, aircraft industry and for Distributed Generation (DG) connected to smart grid. To guarantee the reliability and safety of these systems, the electromagnetic compatibility (EMC) and thermal behavior, have to be carefully considered for these appliances. This paper describes a measurement methodology to characterize the electromagnetic emissions in near field zone produced by a PM prototype and its thermal behavior. In particular, the electric and magnetic fields, in the near field region in the frequency range 9kH…
How can organisations and business models lead to a more sustainable society? A framework from a systematic review of the industry 4.0
2019
The concept of Industry 4.0 has been mainly addressed by the current literature from a technological perspective, overlooking the organisational and even ethical challenges related to this recent paradigm. In order to become &lsquo
Smartness, City Efficiency and Entrepreneurship Milieu
2017
The definition of smart city and its measurement are not shared. Different characteristics define a city as smart, which is strictly linked to urban efficiency and to entrepreneurship spirit in a multifaceted way as well as to citizens’ well-being. On the basis of the comparison between city and entrepreneur behaviour and on the definition of Giffinger et al. (2007) of smart city, this chapter verifies the efficiency of a sample of European cities using a stochastic frontier approach. Departing from this analysis, the chapter develops the relative smartness definition based on the efficient use of its own resources and related to the different context. Moreover, as a city becomes close to t…
A Prototype of Wireless Sensor for Data Acquisition in Energy Management Systems
2018
A prototype of a wireless sensor for monitoring electrical loads in a smart building is designed and implemented. The sensor can acquire the main electrical parameters of the connected load and, optionally, other physical quantities (e.g., room temperature). Unlike other wireless sensors in literature, the proposed sensor is cheap and small, exploits the Wi-Fi network that is commonly available inside buildings, and uses a lightweight message-based communication paradigm. Besides the sensor node, two management nodes are also implemented to manage sensor reconfiguration and the persistence of data. The measured data are stored in an SQLite database and can be used for various purposes, e.g.…
Health & safety 4.0: A digital twin reference model to support the smart operator at the workplace
2020
In the Industry 4.0 era, Cyber-Physical Systems (CPS) and the Internet of Things are the enabling technologies for a new tool, the Digital Twin, that allows a streamlined communication, automation and interoperability among all the production assets. Even if there has been a great deal of efforts toward digital twin engineering, little attention has been paid to the correct integration of humans in the emerging context of smart factories and, in particular, to the potential contribution of digital twins for supporting a health and safety 4.0 at the workplace. This paper sets the stage for a discussion over health and safety aspects for the Smart Operator and proposes a renewed approach to t…
Ética de las capacidades y desarrollo local. Una aplicación de economía, política pública y gobernanza
2015
Las ciudades europeas, cuna de la civilización urbana, se enfrentan a los retos de adaptarse y liderar la transformación del desarrollo urbano consecuencia de la transformación de la base productiva local a través del uso de la tecnología digital, la economía del conocimiento y la sociedad en red. El sistema urbano europeo del siglo XXI, multipolar, caracterizado por ciudades de tamaño medio, está configurando una nueva dimensión de la ciudad a través de nuevas grandes áreas funcionales, necesarias para competir en una economía globalizada. Las regiones metropolitanas, han generado un intenso debate tanto en el mundo académico como en los dirigentes locales sobre el modelo de ciudad que per…
Integration of IEC 61850 MMS and IEEE 802.22 for Smart Grid Communication
2017
The reliability of Smart Grid depends on two-way communication between substation and utility. IEC 61850 is an international standard defined to ensure interoperability between Substation Automation System (SAS). IEC 61850 services are mapped on the Manufacturing Message Specification (MMS) especially for meter data management system. MMS is the OSI protocol that run over TCP/IP or OSI networks to support IEC 61850 services. Presently, the MMS uses Ethernet as the layer 2 protocol. However, for long distance communication in remote areas wireless communication is the prefered mode. The Cognitive Radio based IEEE 802.22 is next generation standard for Wireless Regional Area Network (WRAN) th…
Review of IEEE 802.22 and IEC 61850 for real-time communication in Smart Grid
2015
Real time data communication in Smart Grid is a big challenge due to its vastness and complexities. Wireless Regional Area Network (WRAN) - IEEE 802.22 permits opportunistic use of television white space (TVWS) by secondary user, if it is not being utilized by primary user. This standard has the potential to transfer big data of smart grid in real time to control center. The IEC 61850 is the standard for electrical substation automation that uses TCP/IP for data transfer among different ‘intelligent electronic devices’ (IEDs). IEC 61850 consists of different message types which belong to different performance classes that are mapped to different communication protocols. The different perfor…
Ethical User stories : Industrial study
2022
Publisher Copyright: © 2022 Copyright for this paper by its authors In Port terminals a progressive change is underway in digitalizing traditional systems to SMART systems with the aid of AI. This study follows one of such progressions, the SMARTER project. SMARTER is a sub research and development project of the Sea for Value program of DIMECC company, Finland to create replicable models for digitalization for future terminals which involves the use of AI enabled tools. AI and Autonomous Systems (AS) are the direction that software systems are taking today. But due to ethical challenges involved in the use of AI systems and increased emphasis on ethical practices in the use and design of A…
L’etichettatura di sostenibilità nel settore vitivinicolo
2022
Nel settore vitivinicolo la sostenibilità e la sua comunicazione al consumatore per mezzo dell’etichettatura, nel rispetto della normativa in materia, ha assunto una crescente rilevanza, anche in ragione delle pressanti esigenze ambientali e climatiche che costringono ad un ripensamento in chiave digitale di sistemi e tecniche di produzione, in un’ottica di ottimizzazione e preservazione delle risorse naturali. Partendo da una preliminare riflessione circa il significato giuridico del termine “sostenibile”, il contributo si sofferma su come il legame tra iniziativa imprenditoriale, sviluppo di innovative tecnologie digitali, ricerca di nuovi spazi di mercato e sicurezza giuridica abbia anc…
