On the use of LSPIV-based free software programs for the monitoring of river: testing the PIVlab and the FUDAA-LSPIV with synthetic and real image se…
2020
<p>The development of new image-based techniques is allowing a radical change in the environmental monitoring field. The fundamental characteristics of these methods are related to the possibility of obtaining non-intrusive measurements even in adverse circumstances, such as high flow conditions, which may seriously threaten the operators’ safety conditions in traditional approaches.</p><p>Optical techniques, based on the acquisition, analysis and elaboration of sequences of images acquired by digital cameras, are aimed at a complete characterization of the river instantaneous surface velocity field, through the analysis of a floating…
Improving the multiple errors detection coverage in distributed embedded systems
2004
Currently, a lot of critical applications in automobile and aircraft avionics are built on fault-tolerant real-time distributed embedded systems. Fault injection techniques have been used extensively in the experimental validation of these systems and it is a challenge to adapt them to the demands of new technologies. This paper deals with the effect of physical faults at pin level on the Communication Network Interface in a prototype based on time-triggered architecture. Due to the essential necessity of observing system behavior during injection experiments, a suitable monitor for distributed embedded systems is proposed. The monitor is used to detect failures in the value domain that cou…
Implementation and Experimental Tests of a Management System for MV/LV Distribution Grids
2019
The continuous monitoring of network power flows and the remote control of Distributed Generators and Energy Storage Systems are the essential elements to allow a full exploitation of Renewable Energy Sources and their real integration in distribution networks. Thus in the paper a management system is presented for load flow monitoring in MV/LV distribution network. Moreover, on the basis of calculated power flows, the management system is able to send control commands to DGs and ESSs, to vary their power production or power factor or eventually to disconnect them in order to maintain the network stability. The proposed solution was really implemented in the MV network of Ustica Island, dev…
Computer vision and thermal monitoring of HMPE fibre rope condition during CBOS testing
2020
Abstract Fibre rope usage in deep sea lifting operations is gaining more prominence in recent times. With rope minimum break loads (MBL) comparable to that of their steel wire counterparts, the use of high modulus polyethylene (HMPE) ropes is seen as a viable option for use in subsea construction cranes. The ropes are worn out during use and visual inspection remains one of the main methods of determining whether a fibre rope is to be retired from use, therefore a natural extension is condition monitoring through computer vision. Creep and temperature are constraining with HMPE ropes and should be monitored continuously, particularly when the rope is cyclically bent over sheaves. Additional…

Policy and Governance for Sustainable Consumption at the Crossroads of Theories and Concepts
2016
This introductory article of the special issue compares different conceptual underpinnings of efforts to make the everyday activities of consumers more sustainable. As social practice theory (SPT) is the main theoretical foundation of the articles collected here, we outline its strengths and limitations, when compared with the dominant individual-oriented behaviour change approach, and we focus on theories of planned behaviour, social marketing as well as ‘choice architecture’, based on behavioural economics. This article analyses SPT's usefulness, particularly from the applied point of view for policy-makers and social change programme designers. In the final section we provide some recomm…
Causalities between CO2, electricity, and other energy variables during phase I and phase II of the EU ETS
2010
The topic of this article is the analysis of the interplay between daily carbon, electricity and gas price data with the European Union Emission Trading System (EU ETS) for CO2 emissions. In a first step we have performed Granger causality tests for Phase I of the EU ETS (January 2005 until December 2007) and the first year of Phase II of the EU ETS (2008). The analysis includes both spot and forward markets—given the close interactions between the two sets of markets. The results show that during Phase I coal and gas prices, through the clean dark and spark spread, impacted CO2 futures prices, which in return Granger caused electricity prices. During the first year of the Phase II, the sho…
Transboundary Movements of Hazardous Wastes in International Law: The Special Case of the Mediterranean Area
1997
AbstractSince the early 1980s different organisations have tried to enact international instruments to control international waste trade. The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal was adopted in 1989 under the auspices of UNEP in order to protect human health and the environment against the adverse effects which may result from the management of waste involved in transboundary movements of hazardous waste and its disposal. The Basel Convention has evolved significantly in eight years-whereas only 35 states and the EC signed the Convention at the time of its adoption, more than 113 states have ratified it as to August 1997. Several …
Cefalea persistente in una bambina con rettocolite ulcerosa: pensa alla trombosi venosa
2021
Patients with inflammatory bowel disease have an increased risk of thromboembolic complications, especially during the active phase of the disease. Cerebral thromboembolism is a rare extra-intestinal complication, associated with high risk of morbidity and mortality. Due to the nonspecific clinical presentation and low incidence, a cerebral thromboembolic event may be undiagnosed. For this reason neurological symptoms, such as headache, should not be underestimated in inflammatory bowel disease patients. The paper describes a case of a three-year-old girl with ulcerative colitis complicated by cerebral thrombosis.
Strategic Analysis of The Rural Area Development in the Central Region of Romania
2010
This paper aims at addressing issues of rural development in the Central Region for Development of Romania, in terms of preserving both the traditional aspect of Romania’s rural area and the modernization of rural life for the integration in the European Union. The premise and the importance of such a process are made up by the certainty that the development of rural area and of agriculture in Romania have to be consistent with the values and global beliefs on the environment, agriculture and the role of tradition.
