Optical turbulence measurements and channel modeling of an indoor Free Space Optics link (Versione estesa)
2014
In this work, we propose an indoor experimental set-up able to generate several optical turbulence conditions in a Free Space Optics link. Using this set-up, we prove the effectiveness of an irradiance time-series generator based on the Gamma-Gamma model and able to predict the irradiance fluctuations at the receiver, under both weak and moderate turbulence conditions.
FREE SPACE OPTICS LINKS AFFECTED BY OPTICAL TURBULENCE: CHANNEL MODELING, MEASUREMENTS AND CODING TECHNIQUES FOR ERROR MITIGATION
2014
FSO is an optical wireless line-of-sight communication system able to offer good broadband performance, electromagnetic interference immunity, high security, license-free operation, low power consumption, ease of relocation, and straightforward installation. It represents a modern technology, significantly functional when it is impossible, expensive or complex to use physical connections or radio links. Unfortunately, since the transmission medium in a terrestrial FSO link is the air, these communications are strongly dependent on various atmospheric phenomena (e.g., rain, snow, optical turbulence and, especially, fog) that can cause losses and fading. Therefore, in worst-case conditions, i…

Water distribution network robust design based on energy surplus index maximization
2015
The aim of this paper is to show that energy surplus indices, such as resilience index, besides providing a very good indirect measure of water distribution network reliability to be adopted during the design phase, represent also a valuable and effective indicator of the robustness of the network in alternative network scenarios, and can thus be profitably used in condition of future demands uncertainty. The methodology adopted consisted of (I) multi-objective design optimization performed in order to minimize construction costs while maximizing the resilience index; (II) retrospective performance assessment of the alternative solutions of the Pareto front obtained, under demand conditions…

Positive thinking constitutes one of the great traditions that lead to the idea of the subject as an entrepreneur of himself and is perhaps one of the best that has successfully condensed cultural, political, social and pedagogical processes linked to reflection on well-being in this historical time. The teaching work is especially moved by the pregnancy of these perspectives that challenge the pedagogical field and the education workers as ?agents of change, or at least one more school available to give the discussion on well-being and happiness (yours and the students?) is celebrated and encouraged. In this article, I intend to understand what is being built as pedagogical discourses abou…
La proposta educativa dell'oratorio tra dialogo e testimonianza.
2016
L’oratorio continua ad essere un luogo educativo per tutti i giovani, per lo più di età compresa tra i 6 e i 18 anni, delle famiglie che condividono gli ideali della religione cristiano-cattolica. Esso è anche una palestra formativo-professionale per quei volontari che intendono dedicarsi a compiti educativi. L’uso intelligente del tempo libero dagli impegni di studio, in un clima di letizia e fratellanza, caratterizza l’educazione religiosa offerta ai giovani che frequentano l’oratorio. In alcune “periferie” l’oratorio costituisce l’unico luogo di aggregazione giovanile oltre la scuola. La formazione pedagogica e dottrinale degli educatori che lavorano negli oratori deve essere la prima pr…

Editorial: New Forms of Media Work and Its Organizational and Institutional Conditions
2022
This thematic issue explores the widening scope of media work and the institutional and organizational conditions that support new forms of media work. The media industry has undergone significant economic, structural, and technological changes during the past few decades, including changing patterns of ownership and digitalization of media production, distribution, and consumption. Simultaneously, practices of media work are adopted also in other industries. The 10 articles in the issue not only focus on the new professional roles and responsibilities emerging in the news media industry but also study the practices of media work in organizations in other fields, such as the music industry …

Leisure-time physical activity and participation in organized sports : changes from 1985-2014 in Finland and Norway
2019
Participation in organized sports is a popular and important part of the lives of children and adolescents and is associated with improved psychological and social health, as well as an increased likelihood of meeting physical activity (PA) recommendations. Changes in modern society, including increased car ownership and use of technology and electronic media, have led to an additional focus on the importance of health‐enhancing PA among children and adolescents. The aim of this article was to study the secular changes in self‐reports of participation in organized sports clubs and leisure‐time vigorous physical activity (LVPA), and whether the relationship between participation in organized…
