Energia nel paesaggio:sistemi di produzione di energia elettrica da fonte rinnovabile a Pantelleria

2015

Oramai risulta chiaro a tutti come il mondo in futuro consumerà sempre più energia con un grave peso a livello ambientale. Ma come agire per arginare i danni di tale fenomeno? La risposta, condivisa ormai a livello europeo, è usare l’energia in modo efficiente ed integrare quanto più possibile le fonti di energia rinnovabile all’interno del sistema energetico dei territori. Il lavoro che viene presentato in queste pagine mira a sottolineare come l’integrazione di fonti di energia rinnovabile all’interno di un sistema energetico fortemente dipendente dall’esterno, come quello dell’isola di Pantelleria, risulti un’azione necessaria al fine di migliorare l’efficienza complessiva del sistema e …

A Network Tomography Approach for Traffic Monitoring in Smart Cities

2018

Traffic monitoring is a key enabler for several planning and management activities of a Smart City. However, traditional techniques are often not cost efficient, flexible, and scalable. This paper proposes an approach to traffic monitoring that does not rely on probe vehicles, nor requires vehicle localization through GPS. Conversely, it exploits just a limited number of cameras placed at road intersections to measure car end-to-end traveling times. We model the problem within the theoretical framework of network tomography, in order to infer the traveling times of all individual road segments in the road network. We specifically deal with the potential presence of noisy measurements, and t…

A Middleware to Develop and Test Vehicular Sensor Network Applications

2019

The Smart city ecosystem is composed of several networked devices that provide services to citizens and improve their quality of life. Basic services, which must be exposed by the underlying software infrastructure, require efficient networking and communication protocols to coordinate and manage all the system components. In particular, Vehicular Sensor Networks (VSNs) are envisioned as key components of smart cities. Verification is crucial in such a highly dynamic scenario to ensure operation correctness and to reduce the development cost of smart applications. However, the rigidity of existing middlewares makes development, reconfiguration, and testing rather difficult. In this work, we…

Human Mobility Simulator for Smart Applications

2019

Several issues related to Smart City development require the knowledge of accurate human mobility models, such as in the case of urban development planning or evacuation strategy definition. Nevertheless, the exploitation of real data about users' mobility results in severe threats to their privacy, since it allows to infer highly sensitive information. On the contrary, the adoption of simulation tools to handle mobility models allows to neglect privacy during the design of location-based services. In this work, we propose a simulation tool capable of generating synthetic datasets of human mobility traces; then, we exploit them to evaluate the effectiveness of algorithms which aim to detect…

Evaluating Correlations in IoT Sensors for Smart Buildings

2021

International audience; In this paper we introduce a dataset of environmental information obtained via indoor and outdoor sensors deployed in the SMART Infrastructure Facility of the University of Wollongong (Australia). The acquired dataset is also made open-sourced along with this paper. We also propose a novel approach based on an evolutionary algorithm to determine pairs of correlated sensors. We compare our approach with three other standard techniques on the same dataset: on average, the accuracy of the evolutionary method is about 62,92%. We also evaluate the computational time, assessing the suitability of the proposed pipeline for real-time applications.

Time-Constrained Node Visit Planning for Collaborative UAV-WSN Distributed Applications.

2022

Unmanned Aerial Vehicles (UAVs) are often studied as tools to perform data collection from Wireless Sensor Networks (WSNs). Path planning is a fundamental aspect of this endeavor. Works in the current literature assume that data are always ready to be retrieved when the UAV passes. This operational model is quite rigid and does not allow for the integration of the UAV as a computational object playing an active role in the network. In fact, the UAV could begin the computation on a first visit and retrieve the data later. Potentially, the UAV could orchestrate the distributed computation to improve its performance, change its parameters, and even upload new applications to the sensor network…

OPENSIRACUSA. Una piattaforma WebGIS interoperabile per la tutela, la valorizzazione e la fruizione dei Beni Culturali

Siracusa possiede un ingente patrimonio archeologico e culturale, posto oggi a testimonianza di una delle più grandi e potenti città dell’Occidente antico e giunto a noi tramite complessi meccanismi di stratificazione archeologica e architettonica e in seguito a ripetuti processi di espansione e contrazione del centro abitato nel corso dei secoli. Questo immenso patrimonio, variamente conservato all’interno del tessuto urbano moderno, tuttavia, ha dovuto e deve fare ancora oggi i conti con numerose criticità che rischiano di minarne inevitabilmente la conoscenza, la comprensione e la stessa salvaguardia. In tale quadro nasce OpenSiracusa, un progetto di archeologia pubblica volto alla creaz…

Between the Megalopolis and the Deep Blue Sky: Challenges of Transport with UAVs in Future Smart Cities

2019

International audience; With the rapid increase of the world's urban population, the infrastructure of the constantly expanding metropolitan areas is undergoing an immense pressure. To meet the growing demands of sustainable urban environments and improve the quality of life for citizens, municipalities will increasingly rely on novel transport solutions. In particular, Unmanned Aerial Vehicles (UAVs) are expected to have a crucial role in the future smart cities thanks to their interesting features such as autonomy, flexibility, mobility, adaptive altitude, and small dimensions. However, densely populated megalopolises of the future are administrated by several municipals, governmental and…

Designing Cognitive Cities

2019

The following text intends to give an introduction into some of the basic ideas which determined the conception of this book. Thus, the first part of this article introduces the terms “City”, “Smart City” and “Cognitive City”. The second part gives an overview of design theories and approaches such as Action Design Research and Ontological Design (a concept in-the-making), in order to deduce from a theoretical point of view some of the principles that needs to be taken into account when designing the Cognitive City. The third part highlights some concrete techniques that can be usefully applied to the problem of citizen communication for Cognitive Cities (namely Metaheuristics, Fuzzy Sets a…

Smart Plugs for smarter cities

Load control in modern power grids is becoming more and more important. Recently, energy monitoring and load control has gained interest from several actors such as energy utilities, and Demand Response mechanisms allow consumers to respond to signals from energy suppliers in order to reduce their energy consumption during critical periods, in exchange of discounts on electricity bills. Direct Load Control mechanisms allow energy suppliers, through the adoption of Smart Plugs, to automate load switch-o during such periods. These mechanisms have been traditionally applied to industrial customers only, leaving a major part of loads in the grid, e.g. household appliances, uncontrolled. Commerc…
