A Federated Cloud of Things for Emergency Management
No full textLa ricerca mostrata di seguito mira alla gestione delle emergenze attraverso un'architettura basata
sul Federated Cloud of Things dove le risorse dei cloud sono di computing, storage, networking e
oggetti fisici come sensori e attuatori, sia reali, sia virtuali. Tali risorse, virtualizzate, sono connesse
in una infrastruttura a supporto della gestione delle emergenze.
Infatti, come emerge da report e lavori di ricerca, occorre notare il fatto che, nei recenti anni, le
emergenze come alluvioni, epidemie e terremoti, oltre che emergenze artificiali come atti di
terrorismo, incidenti ferroviari, incidenti nucleari hanno interessato diverse aree sulla terra causando
perdite di vite, feriti e danni economici dei paesi. In questi scenari un sistema efficiente di gestione
delle emergenze e una risposta pronta quando un'emergenza si verifica, sono necessari al fine di
salvare vite umane e limitare i danni al verificarsi di un'emergenza. A tal fine il monitoraggio degli
eventi e delle persone è un'attività fondamentale; tale attività è inoltre necessaria per decidere di
compiere azioni durante le emergenze come, ad esempio, portare le persone in una situazione
sicura. Ciò conduce alla necessità di avere sensori e attuatori che permettono a un sistema di
Emergency Management di gestire opportunamente l'emergenza.S
Inoltre, dato il numero di organizzazioni coinvolte nell'emergenza, emergono alcuni problemi
riguardanti le capacità di collaborazione: spesso le organizzazioni usano sistemi legacy e le
comunicazioni con altri sistemi possono essere difficili, inoltre spesso non è consentito l'accesso
pieno ai sistemi delle organizzazioni ostacolando quindi la condivisione di risorse e/o dati.
Tenendo conto di questi aspetti che interessano le emergenze, questa ricerca propone un framework
che fornisce un infrastruttura per gli Emergency Management System (EMS)
Application of SWSAL in Semantic Annotation of RESTful Web Services
No full textNowadays web services have become one of the main technologies in the development of web applications. According to that providers now offer an increasing number of capabilities as web services. Furthermore, in the recent years, such deployment trend has seen the success of REST architecture and, consequently, the proliferation of RESTful web services. This work focuses on the semantic description of RESTful web services. It shows how the SWSAL language, already used profitably to semantically annotate SOAP web services, can be used to semantically describe a web service compliant with the REST principles. The work establishes the bases for the application of SWSAL and its related researches to the RESTful web service area
Earthquake Emergencies Management by Means of Semantic-Based Internet of Things
No full textSemantic technologies can play a key role in representing,
storing, interconnecting, searching, and organizing information generated/consumed by things. In order to evaluate its feasibility, this paper
presents a set of reasoning mechanisms based on an IoT ontology to be
applied in an emergency management scenario. The scenario presented
in this paper consists in the earthquake emergency management
A semantic-based federated cloud system for emergency response
No full textCloud federation can be described through the concept of collaboration, where each organization has its own cloud(s) that deals with a different and independent domain but needs to work together with other organizations in order to fulfill a specific shared objective. According to this perspective, the federation is a collection of interacting clouds that collaborate with one another through the instantiation and management of shared subsets of resources (computation and storage resources as well as sensors and actuators). This idea could be profitably used in those scenarios in which different organizations have to share several resources (e.g., emergency response or disaster management scenario). On the other hand, when different independent organizations share their resources, several issues arise. One of them is related to interoperability problems. As a consequence, this work also introduces a framework for an ontology-based resource life cycle management and provisioning in a federated cloud infrastructure. Therefore, The main contributions of this work consists of redesigning a cloud infrastructure architecture from the ground up, leveraging Semantic Web and Semantic Web Service Technologies, and natively supporting a federated provisioning of any kind of resource. This paper exploits, as a motivating scenario, a flood emergency response system
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
