Experimentation of sustainable energy microsystems: The DE.DU.ENER.T. research project

2015

The paper focuses on an energy sustainable prototype micro-system installed upon a roof of a building in Valderice (Italy). This micro-system has been conceived in the ENPI (European Neighborhood and Partnership Instrument) cross-border cooperation Italy - Tunisia 2007–2013 DE.DU.ENER.T. (Le DEveloppement DUrable dans la production ENERgetique dans le Territoire) research project framework. The main aim of this project is the construction of a sustainable energy micro-system prototype suitable for the optimal integration and management of renewable energy resources (photovoltaic, wind and solar thermal) and to reduce the building's energy consumption. In the paper the project and the protot…

IMAGE ORIENTATION WITH A HYBRID PIPELINE ROBUST TO ROTATIONS AND WIDE-BASELINES

2022

Abstract. The extraction of reliable and repeatable interest points among images is a fundamental step for automatic image orientation (Structure-From-Motion). Despite recent progresses, open issues in challenging conditions - such as wide baselines and strong light variations - are still present. Over the years, traditional hand-crafted methods have been paired by learning-based approaches, progressively updating the state-of-the-art according to recent benchmarks. Notwithstanding these advancements, learning-based methods are often not suitable for real photogrammetric surveys due to their lack of rotation invariance, a fundamental requirement for these specific applications. This paper p…

Gli obblighi europei di tutela penale dell'ambiente tra responsabilità individuali e corporative. L'attuazione della direttiva 2008/99/CE in Italia, …

La tesi affronta il tema della tutela penale dell'ambiente in chiave europea, vero e proprio banco di prova per le possibilità e i limiti dell'armonizzazione europea dei sistemi penali degli Stati membri. La legislazione ambientale, invero, ha assunto un ruolo emblematico nel percorso che ha condotto alla progressiva estensione della competenza normativa europea al campo penale: è in tale campo di materia, infatti, che si è registrata per la prima volta l'adozione di direttive di armonizzazione penale. Ci si interroga, dunque, sull’ "effetto utile" degli obblighi di criminalizzazione promananti dal legislatore europeo sul fronte dell'armonizzazione delle legislazioni penali nazionali di set…

Keep Calm in Heated Debates: How People Perceive Different Styles of Discourse in a Scientific Debate

2021

Scientific debates are, in an epistemological sense, argumentative approaches aimed at coming to the most appropriate conclusion. However, as these debates sometimes involve interpersonal rather than content-driven attacks (e.g., an argument between scientific experts might involve personal dislike), the following question arises: How do such communication behaviors affect people’s perception of the argument? In an empirical study, we presented prospective teachers (N = 222) with a newspaper article about two scientific experts controversially discussing the pros and cons of a fictional vocabulary training program. Using a 1 × 2 between-subject design, the article contained either a neutral…

An Object Oriented approach for Flexible Manufacturing Control Systems Analysis and Design using the Unified Modelling Language

2003

In reacting to global competition and rapidly changing customer demands, industrial business organizations have developed a strong interest in flexible automation. The aim of flexible automation focuses on achieving agility in handling uncertainties from internal or external environments. Modeling complex structures, promoting reuse, and shortening the development time cycle are particularly significant aspects in the analysis and design of CIM systems, where heterogeneous elements have to be integrated in a complex control architecture. The design methodology for FMS control software involves the abstraction of an FMS and the estimation of the system performances. The aim of this activity …

Tackling Online Disinformation. The Construction of 'Trustworthiness' and 'Best Practices' in the European Commission Discourse on COVID-19

2022

Over the last few decades, misleading healthcare information and deceptions with false claims, conspiracy theories (CTs) and consumer fraud have endangered public health on a global scale. More recently, the COVID-19 pandemic has been accompanied by a substantial flow of false information and unceasing attempts by conspirators to influence debates in the official discourses, breeding on the fertile ground of people’s most basic anxieties and the present-day social and economic uncertainty. This paper investigates the discourse of the European Commission on disinformation in order to achieve institutional legitimation through the linguistic and discursive construction of ‘trustworthiness’, ‘…

A Dataset of Annotated Omnidirectional Videos for Distancing Applications

2021

Omnidirectional (or 360°) cameras are acquisition devices that, in the next few years, could have a big impact on video surveillance applications, research, and industry, as they can record a spherical view of a whole environment from every perspective. This paper presents two new contributions to the research community: the CVIP360 dataset, an annotated dataset of 360° videos for distancing applications, and a new method to estimate the distances of objects in a scene from a single 360° image. The CVIP360 dataset includes 16 videos acquired outdoors and indoors, annotated by adding information about the pedestrians in the scene (bounding boxes) and the distances to the camera of some point…

Transparency in transactive energy at distribution level

2017

A recent report from the German Energy Agency analyzes the possible introduction of the blockchain technology in energy transactions in power distribution. The issue deserves attention since the extensive digitalization of business models puts new challenges to utilities in the power sector. The German decision makers in the energy field claim that blockchain appears as a close perspective and, at the same time, the Gartner hypecycle puts this technology at the peak of inflated expectations in 2016. Diffuse perception however provides hints for further investigation on the topic. This paper provides insight into the problem of peer-to-peer energy exchange from a technical perspective, provi…

Distributed optimal power flow for islanded microgrids: An application to the Smart Polygeneration Microgrid of the Genoa University

2016

In this work, the application of an original distributed optimal power flow method to test a microgrid in the Savona area, Italy is proposed. The microgrid shows different types of Distributed Energy Resources (DERs) and is connected to the main grid through a fixed power bus. Due to the high computational speed, the applied distributed Optimal Power Flow can be performed almost in real time, i.e. every 5 minutes or less. The operating solution found for generators, simply using local information, corresponds to a suboptimal condition with reduced losses, bus voltages and line currents within constrained intervals. The distributed optimization algorithm is iterative, but also fast. It is ba…
