Abstract:
Abstract The purpose of this study is to analyse the interactions established by Gerard Piqué, one of the world’s top defenders, within the general context of the team. The type of interactions (prospective and retrospective) that the player establishes with his team mates and opponents; the parts of the pitch where his actions are set in motion and later finished; his preferred skill or technical moves and finally his influence on set pieces are taken into account. His output throughout the 2012 UEFA Euro, where he played 100% of the game. The instrument of observation proposed by Maneiro & Amatria (2018) has been used. Polar coordinate analysis, a powerful tecnique capable of reducing the amount of data without compromising its analytical capacity, was used. The results showed significant interactions with players from the same and different lines thanks to technical actions of control, pass and carrying of ball. The analysis of the player’s interactions within the general context of the team will provide other teams with tactical alternatives and allow themto organise special training programmes.

Abstract The new Italian building code, published in 2018 [MIT in NTC 2018: D.M. del Ministero delle Infrastrutture e dei trasporti del 17/01/2018. Aggiornamento delle Norme Tecniche per le Costruzioni (in Italian), 2018], explicitly refers to the Italian “Guidelines for the assessment and mitigation of the seismic risk of the cultural heritage” [PCM in DPCM 2011: Direttiva del Presidente del Consiglio dei Ministri per valutazione e riduzione del rischio sismico del patrimonio culturale con riferimento alle norme tecniche per le costruzioni, G.U. n. 47 (in Italian), 2011] as a reliable source of guidance that can be employed for the vulnerability assessment of heritage buildings under seismic loads. According to these guidelines, three evaluation levels are introduced to analyse and assess the seismic capacity of historic masonry structures, namely: (1) simplified global static analyses; (2) kinematic analyses based on local collapse mechanisms, (3) detailed global analyses. Because of the complexity and the large variety of existing masonry typologies, which makes it particularly problematic to adopt a unique procedure for all existing structures, the guidelines provide different simplified analysis approaches for different structural configurations, e.g. churches, palaces, towers. Among the existing typologies of masonry structures there considered, this work aims to deepen validity, effectiveness and scope of application of the Italian guidelines with respect to heritage masonry towers. The three evaluation levels proposed by the guidelines are here compared by discussing the seismic risk assessment of a representative masonry tower: the Cugnanesi tower located in San Gimignano (Italy). The results show that global failure modes due to local stress concentrations cannot be identified if only simplified static and kinematic analyses are performed. Detailed global analyses are in fact generally needed for a reliable prediction of the seismic performance of such structures.

Abstract:
An aim of the experiments is to study alloying techniques of dollop-like MM , as-cast and extruded Mg - MM master alloy in die casting AZ91D magnesium alloy at conventional cold chamber die casting temperature. The as-cast AZ 91 D -1.2 wt % MM alloys were prepared and MM was added by different way at 720°C. The results showed that the efficiency of alloying achieved less than 50% within 30 min when dollop-like MM was added. When MM was added by as-cast and extruded Mg -21 wt % MM master alloy, the efficiency of alloying was improved significantly. The microstructure and analytical studies were carried out using optical microscopy and differential scanning calrimetry (DSC). Testing results showed the Mg - MM master alloy could melt easily down at die casting temperature because Mg - RE phases with lower melting point were formed. The grain refining efficiency of the master alloy was improved by extrusion. The improvement could be attributed to the decrease in Mg - RE particle size and increase in the number of nucleating sizes for Mg . Then die-casting AZ 91 D -0.44 wt % MM test bars were produced with addition of extruded Mg -21 wt % MM master alloy and the efficiency of alloying was around 80%.

Abstract:
Hypertension is a problem that has a social component and a biological one. The history of the biological solutions has been an increase in research activities and an increase in the number of new products introduced in the pharmaceutical market and adopted as usual therapies. This article analyzes each of the main innovations in the treatment of moderate arterial hypertension and their competitive inter-relationships using a conceptual frame based on the recent theory of innovation. These innovations compete with each other for a market, similar to what happens with other areas and products. The concept of trajectories and the analysis of the competition process among them has not previously been applied to a pharmaceutical market and offers an exciting new avenue for insurance organizations, government health agencies, provider groups, and manufacturers to analyze trends and events in an organized and consistent framework. Learning by using, pharmacological interrelatedness, and pharma-institutional networks are the main analytical tools used to explain the competing processes among the different trajectories considered.

Abstract:
Industry 4.0 is the fourth industrial revolution consisting of the digitalization of processes facilitating an incremental value chain. Smart Manufacturing (SM) is one of the branches of the Industry 4.0 regarding logistics, visual inspection of pieces, optimal organization of processes, machine sensorization, real-time data adquisition and treatment and virtualization of industrial activities. Among these tecniques, Digital Twin (DT) is attracting the research interest of the scientific community in the last few years due to the cost reduction through the simulation of the dynamic behaviour of the industrial plant predicting potential problems in the SM paradigm. In this paper, we propose a new DT design concept based on external service for the transportation of the Automatic Guided Vehicles (AGVs) which are being recently introduced for the Material Requirement Planning satisfaction in the collaborative industrial plant. We have performed real experimentation in two different scenarios through the definition of an Industrial Ethernet platform for the real validation of the DT results obtained. Results show the correlation between the virtual and real experiments carried out in the two scenarios defined in this paper with an accuracy of 97.95% and 98.82% in the total time of the missions analysed in the DT. Therefore, these results validate the model created for the AGV navigation, thus fulfilling the objectives of this paper.

Abstract:
Aerosol is of central importance for atmospheric chemistry and physics, for the biosphere, the climate and public health. The primary parameters that determine the environmental and health effects of aerosol particles are their concentration and chemical composition. In this work we have developed the analytical techniques to study particulate matter composition. The knowledge of PM composition can be useful to identify the main PM sources, the health risk and the formation or deposition/removal processes. These analytical techniques have been applied in some field campaign: we have studied the urban particulate matter, the main transport processes sampling in remote sites, the PM concentration and composition in the rural site to estimate the background levels. At the moment EU limits concern only PM10 fraction, but the interest for sub-micron sized particles (PM1) is increasing for their effects on human health and on the environment. We have carried out the first national campaign to study this fraction in three urban sites in Italy. Morevor, for a good comprehension of the complex atmospheric phenomena we have sampled at high resolution time. In the chapter 2 we reported the extraction procedure for ion quantification, to obtaine the good recovery of all ions, the lowest detection limits and to use less portion of sample as possible, to have the possibility to make a large number of analyses on the same sample. The carbonaceous fraction analysis is still object of the discussion in the scientific community, indeed there is not a reference method for this analysis. The key point of this analysis is to separate the main components of carbonaceous particles: organic carbon (OC) and elemental carbon (EC). In the chapter 3 we proposed a new analytical method based on the couple between Thermo Gravimetric Analysis (TGA) with Spectrophotometer Infrared (FT-IR) and in chapter 4 we have reported the intercomparison between this techniques an other analytical method, TOT method by Sunset Instrument. A good comparability is achieved for TC and OC while the agreement is poorer for EC, in accordance with what previously observed by other authors. In the recent years the studies involving the Water Soluble Organic Compounds (WSOC) are increasing because they represent an important portion of OC and can be an important marker of the origin of organic compounds (i.e. biomass burning, ageing). In the chapter 5 the new analytical technique for WSOC quantification using TOT method is reported; the validation of this analytical procedure with a most diffused technique (TOC analyses) is still in progress. In the same chapter we discuss around an hypothetical error in the OC and EC quantification using TOT method: indeed removing the soluble compounds from the sample the contribution of pyrolitic carbon (PyC) decreases and this allows a good determination of the elemental fraction. Nowadays, very few data on the possible contribution of particles emitted by residential wood combustion in Italy are available. In the chapter 7 we proposed a new analytical technique for levogluvoclucosan quantification. Levoglucosan is an anydrosugar specific marker for this source. Usually the anydrosugar in atmospheric aerosol samples is performed by gas chromatography - mass spectrometry (GC-MS), while we have used High Performance Anion Exchange Cromatography coupled with amperometric detection (HPAEC-PAD). This technique was shown to be a high sensitive, relatively simple analytical technique for separation and quantification of anydrosugars in aqueous extract of aerosol particle from biomass combustion. The intercomparison with GC-MS has shown a good comparability for the two techniques. Unlike traditional methods, there is not need for prior chemical derivatization or other complex sample preparation, the extraction procedure for ions quantification is suitable also for this method. The field campaigns were performed thanks to the collaboration between different partners, the Physics Department (University of Genoa), the General Applied Physics Institute (University of Milan), the Physics Department (University of Florence), the National Institute of Nuclear Physics (Florence) and the ARPA Lomabardia are the most important. In Lombardy region atmospheric pollution due to airborne fine particles is an environmental issue of great concern: air quality standards for PM10 are frequently exceeded, especially in Milan. In the ParFiL project by Regione Lombardia we have determined the carbonaceous fraction in about 1000 samples coming from ten different sites (chapter 8) in the Lombardy Region. The carbonaceous compounds are the main constituent of the particulate matter. During the summer the concentrations is quite similar in all urban sites, the average of the concentrations are for the OC 7.4µg/m³ and for EC 1.9µg/m³. During the winter the concentrations are doubled: OC is 15.3µg/m³ and EC is 4.2µg/m³. Milano and Mantova concentration result more correlated in both seasons and the background concentrations measured at Mantova BF resulted strong correlated with the urban concentrations. Using the EC tracer method and the EC concentration in Como (the traffic site) we have estimated that, in the urban site, about the 50% of OC is due to secondary formation; only Milano and Como show a percentage of primary OC higher than the secondary OC. An exhaustive discussion of this method for secondary OC estimation and its comparison with another method (PMF model) is reported in chapter 13). Using levoglucosan as a marker for wood combustion we have estimated the percentage of OC due to this source. In four urban sites, taken as example (Milano, Cantù, Mantova and Sondrio), during the winter time Milan show the lowest value of the OC due to wood combustion (25%), while Sondrio show the highest value (50%) (section 8.3). This preliminary study points out that the magnitude of this source is strong. The transport phenomena have been studied sampling in two remote sites: Monte Cimone, located in the Apennines (2165m asl) (chapter 10) and Bormio S.C. located in the Alps (2200m asl) (chapter 9). With the APCA model we have estimated that the main percentage (60%) of particle on the Monte Cimone site is due to anthropogenic sources. The physical-chemical characterization of PM10 with high temporal resolution campaign (chapter 12) allowed the individuation of the variation of the composition of the PM in the different hours of the day, and also the different magnitude of the sources during the day. The high time resolution sampling allows the study of the atmospheric phenomena (i.e. secondary formation, transport) otherwise hardly appreciable. Sub-micron sized particles (PM1) are of increasing concern owing to their effects on human health and on the environment. To perform the first large scale assessment of sub-micron sized aerosol concentrations, composition and sources, two monitoring campaigns (summer and winter) at three urban sites in Italy (Milan, Florence and Genoa) with different characteristics were performed (chapter 11). The major contributions are due to organic matter (about 30% in summer and 50 % in winter) and ammonium sulphate (about 10 % in winter and 40 % in summer). During the cold season nitrates also contribute up to 30 % in Milan (lower contributions were registered at the other two urban sites). The interest for the effects of air pollution on indoor cultural heritage is increasing. We have studied two different sites: the Ca’ Granda Historical Archive (chapter 14) and the Pietà Rondanini (by Michelangelo) storage room. In one of the two room monitoring in the Ca’ Granda resulted that the air quality is fairly good and it is not so influenced by the outdoor pollution. On the contrary the ambient conditions, in the second one, are quite worrying because of high relative humidity and PM concentration. The Pietà Rondanini storage room is strongly influenced from outdoor ambient. The presence of the visitors favours the growth of pollutants concentrations, the indoor particulate matter composition is similar to outdoor composition. The particulate matter acidity represents a potential risk for the statue.

Abstract:
In questa tesi viene affrontato il tema del tracciamento video, analizzando le principali tecniche, metodologie e strumenti per la video analytics. L'intero lavoro, è stato svolto interamente presso l'azienda BitBang, dal reperimento di informazioni e materiale utile, fino alla stesura dell'elaborato. Nella stessa azienda ho avuto modo di svolgere il tirocinio, durante il quale ho approfondito gli aspetti pratici della web e video analytics, osservando il lavoro sul campo degli specialisti del settore e acquisendo familiarità con gli strumenti di analisi dati tramite l'utilizzo delle principali piattaforme di web analytics. Per comprendere a pieno questo argomento, è stato necessario innanzitutto conoscere la web analytics di base. Saranno illustrate quindi, le metodologie classiche della web analytics, ovvero come analizzare il comportamento dei visitatori nelle pagine web con le metriche più adatte in base alle diverse tipologie di business, fino ad arrivare alla nuova tecnica di tracciamento eventi. Questa nasce subito dopo la diffusione nelle pagine dei contenuti multimediali, i quali hanno portato a un cambiamento nelle modalità di navigazione degli utenti e, di conseguenza, all'esigenza di tracciare le nuove azioni generate su essi, per avere un quadro completo dell'esperienza dei visitatori sul sito. Non sono più sufficienti i dati ottenuti con i tradizionali metodi della web analytics, ma è necessario integrarla con tecniche nuove, indispensabili se si vuole ottenere una panoramica a 360 gradi di tutto ciò che succede sul sito. Da qui viene introdotto il tracciamento video, chiamato video analytics. Verranno illustrate le principali metriche per l'analisi, e come sfruttarle al meglio in base alla tipologia di sito web e allo scopo di business per cui il video viene utilizzato. Per capire in quali modi sfruttare il video come strumento di marketing e analizzare il comportamento dei visitatori su di esso, è necessario fare prima un passo indietro, facendo una panoramica sui principali aspetti legati ad esso: dalla sua produzione, all'inserimento sulle pagine web, i player per farlo, e la diffusione attraverso i siti di social netwok e su tutti i nuovi dispositivi e le piattaforme connessi nella rete. A questo proposito viene affrontata la panoramica generale di approfondimento sugli aspetti più tecnici, dove vengono mostrate le differenze tra i formati di file e i formati video, le tecniche di trasmissione sul web, come ottimizzare l'inserimento dei contenuti sulle pagine, la descrizione dei più famosi player per l'upload, infine un breve sguardo sulla situazione attuale riguardo alla guerra tra formati video open source e proprietari sul web. La sezione finale è relativa alla parte più pratica e sperimentale del lavoro. Nel capitolo 7 verranno descritte le principali funzionalità di due piattaforme di web analytics tra le più utilizzate, una gratuita, Google Analytics e una a pagamento, Omniture SyteCatalyst, con particolare attenzione alle metriche per il tracciamento video, e le differenze tra i due prodotti. Inoltre, mi è sembrato interessante illustrare le caratteristiche di alcune piattaforme specifiche per la video analytics, analizzando le più interessanti funzionalità offerte, anche se non ho avuto modo di testare il loro funzionamento nella pratica. Nell'ultimo capitolo vengono illustrate alcune applicazioni pratiche della video analytics, che ho avuto modo di osservare durante il periodo di tirocinio e tesi in azienda. Vengono descritte in particolare le problematiche riscontrate con i prodotti utilizzati per il tracciamento, le soluzioni proposte e le questioni che ancora restano irrisolte in questo campo.

Abstract:
Il successo nella produzione di cereali, per quanto riguarda la contaminazione fungina durante la fase pre-raccolta, è fortemente correlato alla valutazione del controllo qualità. Lo scopo di questa ricerca è stato quello di studiare come lo zearalenone (ZEN), un metabolita secondario prodotto da diverse specie di Fusarium, sia metabolizzato e modificato nei cereali, come ad esempio il grano e l’orzo. Inoltre, abbiamo sviluppato e ottimizzato metodi analitici per l’identificazione di composti organici volatili (VOC) prodotti dall’interazione tra due specie fungine tossigene selezionate (F. graminearum e F. culmorum) e piante di frumento. L’identificazione di biomarcatori di infezione precoce, all’interno di questi VOC, può contribuire a prevenire/ridurre le contaminazioni all’interno della catena alimentare. Per quanto riguarda la micotossina ZEN, sono stati eseguiti esperimenti “Time Course”. Il grano e l’orzo sono stati trattati con ZEN. I campioni sono stati raccolti in tempi differenti e analizzati con un sistema UHPLC accoppiato ad uno spettrometro di massa QTOF. Il metodo LC-MS è stato ottimizzato per consentire un’analisi veloce, ma comunque in grado di separare i metaboliti target. Per quanto riguarda i composti volatili, le piante di frumento sono state inoculate utilizzando sospensioni di spore dei due funghi selezionati. Le analisi sono state effettuate in differenti fasi fenologiche di crescita. I VOC sono stati campionati direttamente nello spazio di testa di foglie e spighe, mediante microestrazione in fase solida, e analizzati mediante strumentazione GC-MS. Quantità assolute di ZEN e dei suoi metaboliti possono essere riportati rispetto al tempo di raccolta dopo il trattamento. Sulla base del recupero percentuale rispetto al punto zero, si è visto che la maggioranza dello ZEN non è stata metabolizzata dalle piante. I principali prodotti di metabolizzazione sono stati i glucosidi. Invece i dati ottenuti dalle analisi dei VOC sono stati elaborati utilizzando approcci statistici, come la PCA (analisi dei componenti principali), che sottolineano differenze molto importanti tra i campioni. In particolare la maggior parte dei VOC sono stati rilevati durante la maturazione lattea. Tra le sostanze identificate, alcoli alifatici, aldeidi e chetoni sono stati i più abbondanti. Questi composti hanno differenti vie di biosintesi. Per quanto riguarda gli esperimenti “Time Course”, è possibile concludere che la maggior parte dello ZEN rimane non metabolizzata, però abbiamo osservato alcuni glucosidi, in particolare nell’orzo, il quale si è dimostrato più attivo nella produzione di glucosidi rispetto al grano. L’approccio sviluppato nello studio dei volatili ha fornito risultati promettenti nel prevedere il potenziale della formazione della tossina, individuando la presenza di entrambe le specie di Fusarium nelle fasi iniziali della crescita fungina nelle cultivar di frumento.

Abstract:
Il calcio è uno sport di squadra altamente collaborativo. Passare la palla al giocatore giusto è essenziale per vincere una partita, e quindi, anticipare e prevedere le intenzioni del mittente di un passaggio potrebbe arricchire la lista dei cosiddetti “trigger” per l'attivazione o la fine della fase di pressing (collettivo e volto alla sottrazione di soluzioni di gioco dell'avversario) o pressione (individuale e indirizzata al portatore). Il lavoro svolto in questo lavoro di tesi ha lo scopo di analizzare e predire un passaggio, al fine di capire a chi sarà indirizzato. In particolare, sono stati prodotti due modelli rispettivamente per la classificazione del destinatario e della zona di ricezione di un passaggio tramite l’utilizzo di feature geometriche. Un ulteriore studio sperimentale ha visto coinvolto il modello Social LSTM applicato sulle traiettorie prodotte dal pallone e dai giocatori durante un passaggio al fine di prevedere l’andamento della palla. I risultati sperimentali evidenziano come il modello per la predizione del ricevitore possa ottenere un'accuratezza di predizione di oltre il 58% se vengono considerate tre opzioni di passaggio. Nel caso del modello per la classificazione della zona di ricezione i risultati sono più accurati, nello specifico l’accuratezza supera l’80% quando si tiene conto di tre zone. L’applicazione dell’algoritmo Social LSTM per prevedere la traiettoria del pallone dopo un passaggio mostra come tale tecnica, in relazione con dati calcistici, produca dei risultati condizionati da errori e quindi quest’ultima fase ha bisogno di modifiche, al fine di carpire le complesse logiche alla base di un passaggio.

Abstract:
In questa tesi si discuterà ampiamente del recente caso Cambridge Analytica-Facebook, in particolare della profilazione attuata ai danni di 50 milioni di utenti Facebook, a fini elettorali, da parte della società britannica di consulenza politica che si occupava di data mining, web e social media analysis. Si affronterà il tema del meccanismo della manipolazione e persuasione dell’elettorato americano, che vede Facebook come uno strumento dal duplice utilizzo: profilazione e influenza successiva.

Abstract:
La presente ricerca propone una rilettura della questione epistemologica e dello statuto della scienza nel pensiero di Jung, all’interno della generale ricomprensione dell’opera junghiana dopo la pubblicazione del Rotes Buch – Liber novus. L’impianto del lavoro è quindi storico, per i motivi succitati, ma anche teoretico nello stesso tempo, poiché mira a illuminare precisi nessi teoretici al fine di far emerge la risposta di Jung a una serie di domande che attraversano tutta la sua riflessione: è possibile chiamare scienza lo studio della psiche? È lecito rintracciare “un punto archimedeo della psiche”, che ne assicuri la scientificità? Quali sono i criteri euristici ed epistemologici perché si dia scienza di quel contingente fatto di immagini che è la psiche? Il presente lavoro traccia un percorso che dagli anni di apprendistato giovanili, passa attraverso l’esperienza del Rotes Buch, e arriva fino ai testi della maturità. Tra questi particolare attenzione è stata data al saggio del 1952 sulla Synchronizität, vero e proprio laboratorio di quel concetto di scienza che Jung sta elaborando: una scienza empirica, fedele a quei fatti unici e irripetibili che vengono per forza di cose trascurati dalla scienza su base statistica. È questa la posta in gioco nella domanda di senso sulla natura ultima di una scienza della psiche. Come può darsi scienza degli scarti, delle eccedenze, delle pure contingenze infinitesimali? Dinnanzi a simili manifestazioni della realtà l’unico atteggiamento possibile è, secondo Jung, quello dell’empirico, che sta con ciò che accade senza discostarsene. Solo nella misura in cui ci fosse “un punto archimedeo della psiche”, forse, questa scienza della trasgressione, della pura contingenza potrebbe avere un ancoramento esterno. La tensione verso questo “punto archimedeo” ha guidato tutta la costruzione dell’epistemologia e della psicologia complessa di Jung. Attraverso questa prospettiva si comprende come il paradosso dell’empirismo di Jung stia proprio nella natura dell’esperienza psichica: si tratta di un empirismo di dati strutturalmente duplici e ambigui, data la natura intrinsecamente simbolica della psiche. Un empirismo del paradosso, potremmo dire, o del doppio.
The present research offers a re-reading of the epistemological question and of the status of science in Jung's thought, within the general re-reading of his work after the publication of Rotes Buch - Liber novus. For such reason, the work plan is historical; but it is also theoretical, since it aims at illuminating precise theoretical links, in order to highlight Jung's answers to a set of questions that cross his whole production: can the study of the psyche be called ‘science’? Is it legitimate to trace “an Archimedean point of the psyche”, so as to ensure the scientificity of such study? What heuristic and epistemological criteria can produce a science of such contingent set of images as the psyche? The present work traces a path from Jung’s apprenticeship, through the Rotes Buch experience, until his mature production. Among his later texts, particular attention is devoted to the essay on Synchronizität (1952), where Jung elaborates on his very concept of science, i.e., an empirical science, faithful to the unique and unrepeatable facts which are inevitably overlooked by statistical science. This is what is at stake in the question of what the ultimate meaning of a science of the psyche may be. How can one theorize a science of what is discarded, surplus, or pure infinitesimal contingency? In front of such manifestations of reality, the only possible attitude is, according to Jung, an empirical one, which stays close to what is happening without departing from it. Only to the extent that there is “an Archimedean point of the psyche”, perhaps, this science of transgression, of pure contingency might have external anchoring. The tension towards this “Archimedean point” has guided the whole construction of Jung’s epistemology and complex psychology. Through this perspective, one can understand how the paradox of Jung's empiricism lies precisely in the nature of psychic experience: it is empiricism based on structurally dual and ambiguous data, given the intrinsically symbolic nature of the psyche. It is empiricism based on paradox, one could say, or on the double.
