Studio e Analisi delle Prestazioni di Applicazioni basate su Protocolli HTTP/2 e WebSocket

Questo lavoro di tesi studia e analizza le prestazioni di applicazioni basate sui protocolli HTTP/2 e WebSocket, affrontando, anche in maniera sperimentale, due differenti tecniche: polling e push.

Il passaggio dalla Business Intelligence all'Advanced Analytics: individuazione e analisi di un modello in merito all'influenza del lobbying nel sistema economico

I Big Data stanno guidando una rivoluzione globale. In tutti i settori, pubblici o privati, e le industrie quali Vendita al dettaglio, Sanità, Media e Trasporti, i Big Data stanno influenzando la vita di miliardi di persone. L’impatto dei Big Data è sostanziale, ma così discreto da passare inosservato alla maggior parte delle persone. Le applicazioni di Business Intelligence e Advanced Analytics vogliono studiare e trarre informazioni dai Big Data. Si studia il passaggio dalla prima alla seconda, mettendo in evidenza aspetti simili e differenze.

Modello stocastico per la plasticità sinaptica

Nel sistema nervoso centrale i neuroni comunicano l'uno con l'altro attraverso le connessioni sinaptiche e sono soggetti a centinaia di stimoli, ma hanno la capacità di distinguerli l'uno dall'altro. L'abilità delle sinapsi di interpretare questi cambiamenti morfologici e biochimici è detta \textit{plasticità sinaptica} e l'obiettivo di questa tesi è proprio studiare un modello per le dinamiche di questo affascinante processo, da un punto di vista prima deterministico e poi stocastico. Infatti le reazioni che inducono la plasticità sinaptica sono ben approssimate da equazioni differenziali non lineari, ma nel caso di poche molecole bisogna tener conto delle fluttuazioni e quindi sono necessari dei metodi di analisi stocastici. Nel primo capitolo, dopo aver introdotto gli aspetti fondamentali del sistema biochimico coinvolto e dopo aver accennato ai diversi studi che hanno approcciato l'argomento, viene illustrato il modello basato sull'aggregazione delle proteine (PADP) volto a spiegare la plasticità sinaptica. Con il secondo capitolo si introducono i concetti matematici che stanno alla base dei processi stocastici, strumenti utili per studiare e descrivere la dinamica dei sistemi biochimici. Il terzo capitolo introduce una giustificazione matematica riguardo la modellizzazione in campo medio e vede una prima trattazione del modello, con relativa applicazione, sui moscerini. Successivamente si applica il modello di cui sopra ai mammiferi e se ne studia nel dettaglio la dinamica del sistema e la dipendenza dai parametri di soglia che portano alle varie transizioni di fase che coinvolgono le proteine. Infine si è voluto osservare questo sistema da un punto di vista stocastico inserendo il rumore di Wiener per poi confrontare i risultati con quelli ottenuti dall'approccio deterministico.

Estudio, edición crítica y traducción del "Memoriale virtvtvm" de Alfonso de Cartagena

Alfonso de Cartagena (1385-1456), possibly the most representative figure of the courtly, political and cultural dimension built around Juan II, was the third son of the famous convert Pablo de Santa Maria, Burgos’ rabbi and, later on, bishop of that same town. He started his career as governor of Cartagena’s cathedral, afterwards he was named dean of Santiago and Segovia, canon of Burgos and, after his father’s death, bishop of Burgos. Alternatively, he played a vital role in Castile’s national and international politics, as an ambassador in Portugal’s court, at Basel’s council and before Poland’s and Germany’s kings. His work, written both in Latin and Romance, either as an historian, treatise writer, theologist or translator, is quite broad; his literary connections were strong either with Italian humanists or with those who were fond of the language arts from Spain. The first part of this Thesis seeks to provide a wide enough perspective of the author, for which we place the emphasis on the most distinctive aspects of his life. Therefore, we divided the introduction in three sections: a biographical overview, his work and, last, a study on the Memoriale uirtutum itself. Thus, regarding the first aspect, we focus on the course of his life (§1.1), where we can highlight his university education, which isn’t restricted to his training as a jurist, but we also observe that his mental vitality takes him to develop certain inquisitiveness for Moral Philosophy or Latin, which leads him to study Grammar and Rhetoric; this would allow the influence of studia humanitatis to emerge, although he never got to learn the Greek language, as we can deduce from the epistolary confrontation between him and Leonardo Bruni. We also focus on the significance of his Jewish past, upon the defence of the converts during the massacre experienced in the XVth century (§1.2), and on his presence at Basel’s council (§1.3). Despite the fact that his work as a diplomat begins during the missions in Portugal as an emissary of king Juan II, he will get recognition owing to his legation in Basel, not only among the European ecclesiastics, but also among the scholars from Italy; the importance of Basel’s council in Cartagena’s life goes beyond his official work there, either as defending the Castilian interests, or as an active member of the purely conciliar functions, since it also had a huge impact in his intellectual growth. During this time period, Cartagena establishes a friendship with Pizzolpaso, Bishop of Milan, writer, humanist, and friend of Leonardo Bruni. As a result of this type of relationship with men of such high cultural standard, he re-awakens the study of the Classical antiquity among his contemporaries, developing a huge interest in the Greco-Roman masterpieces, which will bring him closely to the highly-regarded Spanish humanists of the XVIth century...

Federative dynamics in the EU under the influence of EU citizenship rights in times of crisis

The federative debate has been tied to the history of the EU integration from the start. Even though the EU is a polity in formation, the comparison with the state model has limited usefulness in assessing the evolution of federative dynamics in the EU. In the context of the EU, federalism should not be regarded as a static arrangement, but rather as a process that has been unfolding despite or because of EU integration setbacks. By the same token, EU citizenship is necessarily distinct from national citizenship. Our purpose in this article is to understand the federative dynamics of the EU in relation to the emergence of a “community of rights”. We also aim to establish if, and how, the on-going crisis has triggered a change in the EU federative process as a result of the weakening/strengthening of citizenship rights.

A auto-interpretação de Husserl em 1930-31: o Nachwort às Ideen como escrito polémico

This essay seeks to expose Husserl’s defensive attitude towards what he calls “the mistaken views” found in the new ways of conducting phenomenology, in the Epilogue to his Ideas. While the polemic side of Husserl’s project, basically but tacitly against Heidegger, is underlined, it is also sustained that this auto-interpretive piece is a fundamental key within Husserl’s corpus in that it defines the direction of the phenomenological project. At the centre of the controversy are the answer to the objections of intellectualism and solipsism, and the disavowal of all forms of anthropologism in the conception of subjectivity.
