A Two-End Traveling Wave Fault Location System for MV Cables
2019
In this paper, a new low-cost device is proposed for fault location in power distribution system. The device is part of a system that should include several units installed in couples at the two ends of medium voltage (MV) cable lines. Their low cost justifies a widespread installation of these devices, moreover other functionalities could be considered so as to enrich the potential of the system for MV cables monitoring and asset management. The system exploits a two-end traveling wave technique, low complexity, and low-cost solutions both for the analog front end as well as for the communication infrastructure. A LoRa network is indeed considered as wireless modulation technique perfectly…
A New Approach for the Reliability of Vehicular Ad Hoc Networks
2018
Vehicular ad hoc networks (VANET), a subset of Mobile Ad hoc Networks (MANETs), is a wireless communication technology applied to transportation, referring to a set of smart vehicles used on the road. These vehicles provide communication services among one another (V2V) or with Road Side Infrastructure (V2I). The main benefits of VANET are enhancing road safety, reducing energy use and emissions, and giving information services. Reliability is one of the most critical issues related to VANET since the information transmitted is distributed in an open access environment. We focused in this paper, on the reliability of VANET as a function of reliable hardware and their functionality taking in…

International experiences in whole of government financial reporting: lesson-drawing for Spain
2009
This article focuses on whole of government accounts from a comparative perspective and identifies key lessons for Spain and other European countries with a continental accounting system. The authors examine the issues involved in whole of government financial reporting in New Zealand, Australia, the UK and North America. They conclude that whole public sector consolidated accounts are not currently feasible in Spain and that consolidation should start at each level of government.
Resource-efficient hardware implementation of a neural-based node for automatic fingerprint classification
2017
Modern mobile communication networks and Internet of Things are paving the way to ubiquitous and mobile computing. On the other hand, several new computing paradigms, such as edge computing, demand for high computational capabilities on specific network nodes. Ubiquitous environments require a large number of distributed user identification nodes enabling a secure platform for resources, services and information management. Biometric systems represent a useful option to the typical identification systems. An accurate automatic fingerprint classification module provides a valuable indexing scheme that allows for effective matching in large fingerprint databases. In this work, an efficient em…
Colloquium: The Shape of Hadrons
2012
This Colloquium addresses the issue of the shape of hadrons and, in particular, that of the proton. The concept of shape in the microcosm is critically examined. Special attention is devoted to properly define the meaning of shape for bound-state systems of near massless quarks. The ideas that lead to the expectation of nonsphericity in the shape of hadrons, the calculations that predict it, and the experimental information obtained from recent high-precision measurements are examined. Particular emphasis is given to the study of the electromagnetic transition between the nucleon and its first excited state, the Δ(1232) resonance. The experimental evidence is critically examined and compare…
Recovery of oil with unsaturated fatty acids and polyphenols from chaenomelessinensis (Thouin) Koehne: Process optimization of pilot-scale subcritica…
2017
The potential effects of three modern extraction technologies (cold-pressing, microwaves and subcritical fluids) on the recovery of oil from Chaenomelessinensis (Thouin) Koehne seeds have been evaluated and compared to those of conventional chemical extraction methods (Soxhlet extraction). This oil contains unsaturated fatty acids and polyphenols. Subcritical fluid extraction (SbFE) provided the highest yield—25.79 g oil/100 g dry seeds—of the three methods. Moreover, the fatty acid composition in the oil samples was analysed using gas chromatography–mass spectrometry. This analysis showed that the percentages of monounsaturated (46.61%), and polyunsaturated fatty acids (42.14%), after appl…
SAGGIO INTRODUTTIVO. FLESSIBILITA' E PRECARIETA' COME POSSIBILITA'
2007
Tiolo corretto: "Flessibilità e precarietà come possibilità" La flessibilità e la precarietà, intese anche come possibilità, sono elemento fondante del fenomeno migratorio. La flessibilità è analizzata nell’ottica della globalizzazione. La flessibilità e la precarizzazione dell’occupazione diventano anche fonte di precarizzazione nella vita privata. Pur in questo contesto, la flessibilità ha caratteristiche particolari, vissuta come “possibilità”, legata al desiderio di più tempo libero di cui ci si può riappropriare; dell’opportunità soprattutto per le donne di inserimento sociale e di assistenza, attraverso i servizi del welfare, ma anche il loro vivere la flessibilità come la possibilità…
