A Fog-Based Application for Human Activity Recognition Using Personal Smart Devices

2019

The diffusion of heterogeneous smart devices capable of capturing and analysing data about users, and/or the environment, has encouraged the growth of novel sensing methodologies. One of the most attractive scenarios in which such devices, such as smartphones, tablet computers, or activity trackers, can be exploited to infer relevant information is human activity recognition (HAR). Even though some simple HAR techniques can be directly implemented on mobile devices, in some cases, such as when complex activities need to be analysed timely, users’ smart devices can operate as part of a more complex architecture. In this article, we propose a multi-device HAR framework that exploits the fog c…

Three-dimensional matching based resource provisioning for the design of low-latency heterogeneous IoT networks

2019

Internet-of-Things (IoT) is a networking architecture where promising, intelligent services are designed via leveraging information from multiple heterogeneous sources of data within the network. However, the availability of such information in a timely manner requires processing and communication of raw data collected from these sources. Therefore, the economic feasibility of IoT-enabled networks relies on the efficient allocation of both computational and communication resources within the network. Since fog computing and 5G cellular networks approach this problem independently, there is a need for joint resource-provisioning of both communication and computational resources in the networ…

WiP: Smart services for an augmented campus

2018

Technological progress in recent years has allowed the design of new intelligent learning systems in smart environments aiming to facilitate users' lives. As a consequence, besides making use of traditional sensors for monitoring the quantities of interest, such systems can also benefit from information obtained from the users' smart devices, which can now be considered as additional sensing tools. In this article, we present the design of a novel system based on the fog computing paradigm that can improve the services offered to users on a smart campus by using different smart devices, i.e., smartphones, smartwatches, tablets, smartcameras and so on. In particular, we will describe a syste…

A fog-based hybrid intelligent system for energy saving in smart buildings

2019

In recent years, the widespread diffusion of pervasive sensing devices and the increasing need for reducing energy consumption have encouraged research in the energy-aware management of smart environments. Following this direction, this paper proposes a hybrid intelligent system which exploits a fog-based architecture to achieve energy efficiency in smart buildings. Our proposal combines reactive intelligence, for quick adaptation to the ever-changing environment, and deliberative intelligence, for performing complex learning and optimization. Such hybrid nature allows our system to be adaptive, by reacting in real time to relevant events occurring in the environment and, at the same time, …

«Largo a noi, all’alta battaglia»: l’engagement di Zola nella ricezione italiana

2016

Germinal, uscito sul “Gil Blas” dal 25 novembre 1884 al 24 febbraio 1885, e nel marzo 1885 in volume, tradotto e pubblicato contemporaneamente in Italia sulla “Tribuna”, da sempre tra i libri più noti e amati di Zola, è la storia della vita in un distretto minerario, di un lungo e tragico sciopero, dell’espansione dell’Internazionale socialista: prende il titolo da quello che nel calendario della Rivoluzione francese è il primo mese di primavera, e annuncia un’altra rivoluzione. È un romanzo complesso, per più versi ambivalente: evidenzia l’esigenza della protesta, ma anche i torti dei leader politici e l’inclinazione delle masse alla violenza; alterna descrizioni meticolose a possenti imma…

Interventi su volte sottili di mattoni in foglio in Sicilia (Intervention on tiled vaults in Sicily)

2016

Recenti studi hanno confermato come la diffusione nella Sicilia occidentale delle volte sottili di mattoni in foglio (“realine”) sia avvenuta in maniera estesa dalla seconda metà del secolo XVIII ai primi decenni del Novecento, sia negli orizzontamenti e nelle scale dell'edilizia corrente, che con funzione portante e di soffittatura nelle architetture nobiliari. Per finalità di studio o professionali se ne sono analizzati i caratteri costruttivi, le costanti e le variabili, con verifiche su strutture che hanno superato indenni le prove del tempo. In laboratorio o nei cantieri sono state effettuate sperimentazioni accademiche ed interventi di recupero, con ricostruzioni parziali o totali e i…

Timbrel vaults in Sicily. Constructive techniques and intervention methodologies

2017

Tra le tante tipologie di volte riscontrate sul territorio siciliano finalizzate a coniugare economia e leggerezza senza perdere in sicurezza, vengono in questo studio analizzate quelle costituite da due, tre o quattro fogli di mattoni sottili uniti con gesso (volte realine secondo la definizione locale). Non si hanno notizie certe sull’origine di queste volte che, probabilmente introdotte dall’area iberica in Sicilia nella prima metà del XVIII secolo, evidenziano come un sistema costruttivo importato da aree geografiche spesso molto distanti possa essere reinterpretato in funzione dei materiali disponibili e della cultura edilizia locale. Ciò ha in più occasioni determinato soluzioni origi…

Effects of organic aerosol constituents on extinction and absorption coefficients and liquid water contents of fogs and clouds

1978

We have speculated on the influence of organic material on extinction and absorption coefficients and liquid water content of fogs and of clouds immediately after their condensational stage. It results therefore, that the reduction of the speed of growth from fog to cloud droplets due to the presence of organic films largely reduces the properties mentioned. Compared to that their increase coming from the surface tension reduction due to organic material being dissolved or building up films is expected to be less effective.
