Cyber-Security in Digital Metering Value Chain for Mountain Landslide Warning
2021
The Norwegian Water Resources and Energy Directorate (NVE) are initiating a digitalization process that involves the use of a digital metering value chain and cloud computing. The main objective of this study is to investigate how NVE can ensure cyber-security in digital meters and the cloubased metering value chain for mountain landslide warning. The study is based on a qualitative approach including methods like document analysis and semi structured interviews used as input to a risk analysis based on the ISO 31000 standard. The risk analysis covered three different scenarios from NVE. Those three scenarios were internal, external Norwegian, and transnational value chains for metering lan…
Self-configuring multipath intra-mesh infrastructure QoS based routing
2016
International audience; Multi-path routing concept was largely exploited in wireless networks to provide benefits such as fault tolerance, load balancing, performance improvement in terms of latency, etc. In this paper, we propose a multi-path routing based protocol named MP-IMRR (Multi-path Intra-Mesh infrastructure Routing protocol) to improve our previously defined QoS based routing protocol for wireless mesh networks (i.e. IMRR). MP-IMRR is defined in order to achieve better reactivity and faster recovery from eventual route failures than the IMRR protocol by adopting the backup routes concept. Besides, given the complexity increase while considering network management systems, we adopt…
Recyclage et Résilience. La fin des oppositions
2018
Riciclo e Resilienza sono due fra le principali parole-chiave che hanno attraversato il rapporto fra architettura e città degli ultimi quarant'anni. Facendo riferimento ad alcuni esempi prodotti nel periodo, il saggio coglie il loro diverso ruolo euristico e statuto estetico ponendoli in rapporto alla trasformazione della nozione di ecologia. Evolvendo attraverso posizioni tardo darwiniste, l'integrazione delle dimensioni economica, geografica, tecnica e sociale nella nozione di ecologia operata da Banham, fino alla più recente appropriazione della nozione di capacità di ricostruirsi dopo un trauma, si chiariscono le fonti e i fondamenti concettuali che guidano questi due motori recenti del…
UAV Communication Strategies in the Next Generation of Mobile Networks
2020
| openaire: EC/H2020/857031/EU//5G!Drones The Next Generation of Mobile Networks (NGMN) alliance advocates the use of different means to support vehicular communications. This aims to cope with the massive data generated by these devices which could affect the Quality of Service (QoS) of the associated applications, but also the overall operation carried out by the vehicles. However, efficient communication strategies must be considered in order to select, for each vehicle, the communication mean ensuring the best QoS. In this paper, we tackle this issue and we propose efficient communication strategies for Unmanned Aerial Vehicles (UAVs). In addition to direct UAV-to-Infrastructure communi…
Quali piani per i porti italiani? Ripresa (economica) e resilienza (del monadismo) nell’ultima disciplina della pianificazione portuale
2022
Il “Decreto Infrastrutture”, convertito in legge nel novembre 2021, ha modificato la disciplina dettata dall’art. 5 della legge n. 84/1994, introducendo meccanismi di semplificazione delle procedure di pianificazione portuale il cui scopo è garantire massima celerità alle decisioni concernenti l’infrastrutturazione dei sistemi portuali nazionali. Questa riforma del quadro normativo si traduce in un profondo ripensamento degli obiettivi originari della legislazione in materia: la coerenza interna della pianificazione portuale, il raccordo armonico tra quest’ultima e la pianificazione urbanistica, la ricerca di una sinergia tra la pianificazione dei sistemi portuali e la pianificazione dei tr…
Process reference frameworks as institutional arrangements for digital service innovation
2020
Abstract Information systems (IS) service organizations are increasingly more concerned with their ability to co-create digital services with customers in service ecosystems. Practitioners and researchers, however, lack understanding of which organization mechanisms effectively contribute to IS organizations’ innovation practices. Grounded in service-dominant logic, we hypothesized that process reference frameworks (PRFs), such as the IT Infrastructure Library (ITIL), act as institutional arrangements through their norms, rules, and practices, enhancing IS organizations’ ability to innovate digital services. Data collected from 159 IS organizations confirmed our hypotheses, showing that eff…
Evaluating Infrastructure Alternatives for Regional Water Supply Systems by Model-assisted Cost-benefit Analysis – A Case Study from Apulia, Italy
2014
The main challenge associated to regional water supply systems planning lies in understanding the best infrastructure alternatives to improve service given a certain configuration of the resources system. While cost-effectiveness assessments are still widespread in this type of analyses, they do not account for the fact that, especially in mature systems, service improvements tend to follow the law of marginal diminishing returns, so that a cost – benefit assessment should be preferable. Both costs and benefits can be organized into a cost-benefit analysis (CBA) framework. In a complex system, a model reproducing its topology and characteristics better describes the impacts of the alternati…
Integrating Variability Management in Data Center Networks
2017
International audience; Data centers have an important role in supporting cloud computing services (i.e. checking social media, sending emails, video conferencing,..). Hence, data centers topologies design became more important and must be able to respond to ever changing service requirements and application demands. An ultimate challenge in this research is the design of data center network that interconnects the massive number of servers, and provides efficient and fault-tolerant routing algorithm. Several topologies such as DCell, FlatNet and ScalNet have been proposed. However, these topologies generally seek to improve the scalability without taking into consideration the energy usage …
IoT monitoring of urban tree ecosystem services: Possibilities and challenges
2020
Urban green infrastructure plays an increasingly significant role in sustainable urban development planning as it provides important regulating and cultural ecosystem services. Monitoring of such dynamic and complex systems requires technological solutions which provide easy data collection, processing, and utilization at affordable costs. To meet these challenges a pilot study was conducted using a network of wireless, low cost, and multiparameter monitoring devices, which operate using Internet of Things (IoT) technology, to provide real-time monitoring of regulatory ecosystem services in the form of meaningful indicators for both human health and environmental policies. The pilot study w…
