Evaluation of the Effectiveness of Piracy Shield through Video Stream Analysis and its Operation
No full textopenIl presente documento descrive il lavoro svolto durante il periodo di stage interno, della
durata di circa trecentoventi ore, dal laureando Maffei Davide presso l’Università degli
Studi di Padova. Il tirocinio è stato portato a termine sotto la supervisione del Prof.
Alessandro Galeazzi, che ha ricoperto il ruolo di proponente, e con il supporto del Dott.
Giacomo Quadrio e del Dott. Enrico Bassetti, membri del gruppo di ricerca SPRITZ
del Dipartimento di Matematica dell’Università di Padova.
Il progetto di stage si concentra sull’analisi del traffico di rete che transita attraverso
lo snodo VSIX e sulla sicurezza informatica, con particolare attenzione a problematiche legate alla riproduzione illegale di contenuti in streaming. L’obiettivo è quello di
stabilire delle tecniche pratiche e teoriche per l’analisi di dataset complessi, al fine
di classificare i diversi tipi di flussi di dati e identificare il traffico illegale. Il progetto
nasce dall’esigenza di raccogliere informazioni sul funzionamento di Piracy Shield,
nonché sulla valutazione della sua efficacia. Attraverso l’analisi dei flussi di rete, si
vuole riuscire a distinguere i flussi video dagli altri tipi di traffico e a identificare le
differenze tra il traffico ordinario e quello piratato.
Gli obiettivi del progetto includono l’acquisizione di competenze nella manipolazione
di grandi dataset di traffico di rete, la progettazione e implementazione di un sistema
di classificazione dei flussi, e l’identificazione di traffico legale e illegale utilizzando
tecniche avanzate di analisi dei dati.This document describes the work carried out during the internal internship period of the
duration of approximately three hundred and twenty hours, by the graduate Maffei Davide at the University of
Padua studies. The internship was completed under the supervision of Prof.
Alessandro Galeazzi, who acted as proposer, and with the support of Dr.
Giacomo Quadrio and Dr. Enrico Bassetti, members of the SPRITZ research group
of the Department of Mathematics of the University of Padua.
The internship project focuses on analyzing the network traffic that passes through
the VSIX hub and on IT security, with particular attention to problems related to the illegal reproduction of streaming content. The goal is to
establish practical and theoretical techniques for the analysis of complex datasets, in order to
to classify different types of data flows and identify illegal traffic. The project
was born from the need to collect information on the functioning of Piracy Shield,
as well as on the evaluation of its effectiveness. Through the analysis of network flows, yes
wants to be able to distinguish video streams from other types of traffic and identify the
differences between ordinary and pirated traffic.
The objectives of the project include the acquisition of skills in manipulation
of large datasets of network traffic, the design and implementation of a system
flow classification, and the identification of legal and illegal traffic using
advanced data analysis techniques
Villaggio ENI: architettura per un’idea. Significato, realtà, prospettive
No full textAlla metà degli anni Cinquanta Enrico Mattei, presidente dell’ENI, affida all’architetto Edoardo Gellner la progettazione di un villaggio di vacanza per i dipendenti dell’azienda, nella località di Borca di Cadore, sulle Dolomiti. I principi ispiratori del progetto sono tracciati secondo la visione della società sognata da Mattei, in cui l’elevata qualità architettonica è accessibile a tutti, senza distinzioni sociali. La progettazione di Gellner è totale, e riguarda tutti gli aspetti che vanno dall’inserimento territoriale all’arredo degli interni. La valenza ideale e sociale dell’iniziativa, che scaturisce dalla capacità rivoluzionaria dell’idea, e la sapiente architettura, che le da forma, mantengono ancora tutta la propria urgente attualità
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
