A Test for the Divergence of Certain Series with Positive Terms
No full textIn this short note we prove a simple divergent test for certain series with positive terms which are related in some way with the Theory of Dirichlet’s series
On Certain Conditionally Convergent Series
No full textIn this paper we investigate the problem of the convergence
of a very special kind of non absolutely convergent series
which can not be solved by means of traditional tests as Dirichlet test
RSSA: a Rejection-based Stochastic Simulation Algorithm
No full textIn this study we propose an improvement for the stochastic simulation algorithm (SSA), a standard method to properly realize the stochastic nature of biochemical reactions. Our algorithm is named {\em RSSA} after ``rejection-based SSA'', and is tailored for the efficient simulation of large models, which is typically done to understand the complex behavior of regulatory systems. The large models are highly coupled, and full of interconnection and feedback loops. In addition, in these models a compex propensity function is often used to express the stochastic rate of biochemical reactions. Evaluating and updating the reaction propensities is therefore rather computationally expensive. RSSA reduces this computational burden by postponing the full update and only computing the propensity as needed. We experiment with our algorithm on concrete biological models to demonstrate its efficiency
Maximum Efficiency Arrays for WPT
No full textPlanar arrays with maximum beam efficiency are addressed in this report. The objective of the synthesis process is the maximization of the ratio between the power sent to a target area to the total transmitted power. The optimal tapering is analytically found as the solution of a generalized eigenvalue problem whose matrices are either computed in closed-form or obtained through numerical integration depending on the problem scenario
Looking for a Feasible form of Software Protection : Copyright or Patent, is that the Question?
No full textSoftware presents important aspects of heterogeneity compared to other intellectual works governed by Intellectual Property Rights (IPRs). This paper focuses on the analysis of the two main forms of software protection (copyright and patent), providing some considerations towards the proposal of a feasible system
Granular flow-collisional regime

L'Italia al Palazzo di Vetro: aspetti dell’azione diplomatica e della presenza italiana all’ONU
No full textNel mondo accademico le conoscenze relative alle
organizzazioni internazionali sono spesso concentrate sui profili giuridici e istituzionali, e solo sporadicamente coprono attività complesse come quelle in cui si concretizzano mediazioni e negoziati che quotidianamente coinvolgono i delegati dei 191 Stati membri delle Nazioni Unite nonché gli Osservatori permanenti.
Questa pubblicazione, e ancor prima i seminari che ne sono
stati alla base, non pretende di coprire esaustivamente l’intera gamma di attività dell’ONU. Più modestamente, si propone di offrire un contributo per spiegare più da vicino – attraverso alcune testimonianze – come opera concretamente la diplomazia multilaterale, ed in particolare quella delle Nazioni Unite a New York
Plagio, proprietà intellettuale e musica: un'analisi interdisciplinare
No full textQuesta tesi si propone di affrontare con taglio critico e marcatamente interdisciplinare le problematiche relative al plagio musicale con particolare riferimento alle opere di musica leggera. Il tema viene affrontato secondo una prospettiva prima sostanziale, poi processuale ed in ultimo attraverso contributi riferibili ad ambiti disciplinari lontani da quello giuridico. In particolare si esamina l’iter processuale posto in essere dalle corti italiane e statunitensi per l’accertamento del plagio musicale cercando di evidenziare i limiti insiti nel frequente ricorso al parametro dell’“ascoltatore-medio”. Ricorrendo a diverse discipline come la scienza computazionale, la sociologia della musica, la semiotica musicale e le scienze cognitive si cerca di testare la validità “scientifica” dei parametri utilizzati dalle corti vagliando, in ultimo, le possibili implicazioni che alcune acquisizioni delle scienze cognitive (come la “cryptomnesia” e l’ “inadvertent plagiarism”) potrebbero determinare sulla definizione dei concetti di creatività e di plagio in ambito musicale.
ENGLISH ABSTRACT
This thesis is intended to deal with plagiarism in music, particularly pop music, by adopting a critical and interdisciplinary approach. It addresses the topic from a substantive and procedural law perspective, examining plagiarism trials in Italian and U.S. courts. Specifically, having regard to the contribution of various disciplines, which include computer science, sociology of music, musical semiotics and cognitive science, this essay seeks to test the scientific validity of parameters that courts commonly use to demonstrate plagiarism, by also referring to the “average listener” criterion. Finally, this thesis evaluates the implications of cognitive science theory for defining concepts such as creativity, “inadvertent plagiarism” and “cryptomnesia”
Beni comuni digitali come fenomeno spontaneo = Digital Commons as a Spontaneous Phenomenon
No full textQuesto lavoro esplora la natura spontanea dei beni comuni digitali – dal software libero all'open science e all'open data – e gli strumenti istituzionali funzionali alla loro gestione.
ENGLISH ABSTRACT
This paper explores the spontaneous nature of the so called digital commons -- from free software to open science and open data -- and the institutional tools needed for their management
Imposing a Semantic Schema for the Detection of Potential Mistakes in Knowledge Resources
No full textSociety is becoming a complex socio-technical ecosystem requiring novel ICT solutions to provide the basic infrastructure for innovative services able to address key societal challenges and to assist people in their everyday activities. To tackle such complexity, there is a pressing need for very accurate, up-to-date and diversity-aware knowledge resources which can guarantee that results of automatic processing can be trusted enough for decision making processes. As the maintenance of such resources turns out to be very expensive, we argue that the only affordable way to address this is by complementing automatic with manual checks. This paper presents a methodology, based on the notion of semantic schema, which aims to minimize human intervention as it allows the automatic identification of potentially faulty parts of a knowledge resource which need manual checks. Our evaluation showed promising results
