Rota, Gabriele. "The textual transmission of Cicero's Epistulae ad Brutum, ad Quintum fratrem, and ad Atticum". Thesis, University of Cambridge, 2018. https://www.repository.cam.ac.uk/handle/1810/277880.
Testo completoAbstract (sommario):
My doctorate is a study of the manuscript transmission of Cicero’s Epistulae ad Atticum: a twenty-book corpus comprising one book Ad M. Brutum, three books Ad Quintum fratrem, sixteen books Ad Atticum and a pseudo-Ciceronian Epistula ad Octauianum. I have made a complete reinspection and partial recollation of the eighty-odd fully extant manuscripts, and reconstructed a new stemma codicum that may be used for both historical and editorial purposes. My thesis consists of four chapters, following the transmission of the corpus of Ad Atticum from the Middle Ages down to the Renaissance and the beginning of printing. In Chapter 1 I discuss the top of the stemma: Petrarch’s (1304–74) rediscovery of these letters in the Chapter Library of Verona in 1345, and the beginning of their dissemination in fifteenth-century Italy, thanks to the Florentine Chancellor Coluccio Salutati (1331–1406) and two humanists of his circle: Niccolò Niccoli (1364–1437) and Leonardo Bruni (c. 1370–1444). Editors of Cicero’s letters believe that the top of the stemma is bipartite, and that bipartition reflects separate strands of mediaeval transmission: I argue against their reconstruction and put forward a new pluripartite stemma. In Chapter 1 I also consider manuscripts independent of the Verona archetype: these witnesses survive only in tiny fragments and scattered readings cited by sixteenth-century critics. In Chapter 2 I study the northern Italian progeny of the Veronese archetype: here too I have significantly improved on the editors’ work, thanks to collation of a larger number of independent manuscripts and a more articulated understanding of the intricate dynamics of contamination affecting this branch. In Chapters 3 and 4 I investigate the Florentine transmission of the corpus of Ad Atticum. In Chapter 3 I study the closer descendants of the copy of the Verona archetype that in 1393 came from Milan to Florence at Salutati’s instigation. In Chapter 4 I focus on the thirty-odd descendants of the manuscript that in 1408 the humanist and Papal secretary Poggio Bracciolini (1380–1459) copied for Cosimo de’ Medici (1389–1464). The comprehensive stemmata that I put forward in Chapters 3 and 4 are completely new, since hitherto there has been no systematic attempt to map the genealogy of Salutati’s manuscript.

Testo completoAbstract (sommario):
Ioannes Fuxius per Aevum quod dicitur Baroccum, quo tempore gustus musici celeriter mutabantur, musicum enchiridion palmare, cui titulus Gradus ad Parnassum, edidit. Quo libro modos musicos componendi ratio aetate artium renatarum exorta cum ratione aevo Barocco usitata coniungitur. Auctor historiam artis musicae, vocabula artis propria, normas hoc opere docet per dialogum Latinum et faberrime scriptum, qui inter Palestrinae personam et eam discipuli personam, quam auctor ipse agit, habetur. At nostris temporibus Fuxius innotuit, quod quasi ante omnium oculos regulas uniuscuiusque Speciei Contrapuncti posuit. Liber eius igitur in multos sermones vernaculos est versus etiam paucis annis post primam divulgationem. Nunc temporis quoque in scholis musicis in omnibus orbis terrarum partibus sitis docetur. Hanc commentatiunculam paravi in usum discipulorum qui capita, ubi Species Contrapuncti duarum vocum enodantur, Latino sermone primigenio atque perlucido legere vellent.
During the Baroque Era, a time of quickly-changing musical tastes, Johann Fux wrote a seminal music composition textbook, the Gradus ad Parnassum, that bridges the gap between Renaissance Counterpoint and High Baroque Style. Through the beautifully-written, Latin dialog between a teacher (in the persona of Palestrina) and a student (Fux himself), the author teaches the reader about the history, nomenclature and norms of composition. Today the name Fux is synonymous with Species Counterpoint and his celebrated text, translated into many vernacular languages within years of its first publication, is read in music-theory classrooms around the world. This commentary is prepared for the use of students who wish to read the chapters on two-voice Species Counterpoint in the original, and highly accessible Latin.

Testo completoAbstract (sommario):
Lo scopo di questa tesi è stato la produzione di un elettrolizzatore ad ossidi solidi (SOEC) mediante tecniche economiche e facilmente industrializzabili. Fondamentale a questo scopo è stata la realizzazione di una semicella costituita da un anodo poroso a base di La0.8Sr0.2MnO3-Ce0.8Gd0.2O2-δ (LSM-GDC) ed un elettrolita denso a base di Ce0.8Gd0.2O2-δ (GDC). Le tecniche utilizzate per la produzione di questo sistema sono state il colaggio su nastro e la serigrafia. Anche se generalmente, le celle SOEC vengono prodotte catodo supportate, in questo studio, l’elemento supportante scelto è stato l’anodo poiché questo garantisce una migliore stabilità meccanica all’intera cella. Tale substrato è stato ottenuto mediante colaggio su nastro accoppiato con un metodo innovativo di sinterizzazione denominato sinterizzazione reattiva, processo che prevede la formazione della fase di interesse durante un unico trattamento termico di eliminazione degli additivi organici e consolidamento del manufatto finale. La membrana elettrolitica per l’ottenimento del bilayer anodo-elettrolita, è stata prodotta mediante sia serigrafia che colaggio su nastro. L’accurato studio dell’evoluzione di fase della polvere anodica, l’ottimizzazione della sospensione per colaggio su nastro e dei trattamenti termici hanno permesso l’ottenimento di anodi (fino a dimensioni di 10x10 cm2). Lo studio dei profili di sinterizzazione delle polveri anodica ed elettrolitica e dell’influenza della tecnica di formatura sulla sinterabilità dei layer elettrolitici prodotti hanno inoltre permesso l’ottenimento di una semicella planare costituita da un elettrodo poroso ed una membrana elettrolitica densa adatte per applicazioni SOEC.The aim of this thesis was the production of a solid oxide electrolyzer cell (SOEC) through cheap and easily scalable techniques. For doing so the most important step is the production of the bilayer supporting electrode/electrolyte. Therefore a half-cell constituted by a porous La0.8Sr0.2MnO3-Ce0.8Gd0.2O2-δ (LSM-GDC) anode and a dense Ce0.8Gd0.2O2-δ (GDC) electrolyte was produced. Tape casting and screen printing were the techniques used for the production of this bilayer. Even if, the typical supporting element for an electrolyzer cells is the cathode, in this study an anode-supported cell was produced in order to assure a better mechanical stability. The supporting anode was produced by tape casting using an innovative sintering method called reactive sintering. With this method the final phase was obtained during a single thermal treatment that included also the organic removal and the final consolidation of the substrate. The electrolytic membrane was produced using either screen printing and tape casting. Anode substrates (of dimensions up to 10x10 cm2) were produced though a careful study of the phase evolution of the anodic reagents powder, the optimization of the tape casting slurry and the thermal treatments of debonding and sintering. The careful study of the sintering profiles of the anodic and electrolytic powders and of the effect of the shaping method on the sintering properties of the electrolyte layers allowed the production of flat half-cell constituted of porous electrode and dense electrolyte, suitable for SOEC application.

Björk, Åsa. "AD/HD i förskolan". Thesis, Karlstad University, Karlstad University, Karlstad University, 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:kau:diva-3162.
Testo completoAbstract (sommario):
In this work, I have studied whether if one can detect AD / HD in preschool. I have read some literature and searched on the Internet. I have also tried to get to interview people who are familiar with this topic, which has not been easy. I have questioned 13 persons if they would participate in an interview, but most have refused because they do not have time. I succeeded anyhow to get three persons, two special educators and a nurse on the BVC. Special Student teachers are working to put the various educational activities in the preschool / school when children are in need of assistance. Children nurse is working with children to look up at the controls as they come in and where they can see if there is something not as it should. The answer I came up with through the literature and interviews is that AD / HD is a neuro-psychiatric disability and is logically divided into three groups that they have to Impulsivity problems, over activity and attention problems. Special Student teachers tell of the symptoms / signs of AD / HD as the first notice are that the children with AD / HD have problems in concentrating in a task. What distinguishes boys from girls is that boys are more hyperactive and ports in more trouble than girls do. Girls are more reclusive and shy and have been easier to become depressed and anxious. It is difficult to detect AD / HD in preschool unless the kids have severe problems with attention, impulsivity and over activity
I also got answer to that one can detect AD / HD if you're looking for it, but it’s not the essential, the important is to support children with AD / HD in the learning and development. Special Student teachers talked a lot of work how to help children in preschool with various educational activities such as solid framework, transparency and daily schedules. They can also work in small groups but that is not always suitable for all children. Then we can bring the children who have problems at the front near the teacher in order to give praise and jacking.

Testo completoAbstract (sommario):
Marketers often target women because they represent over half of the population in Canada and Sweden and because they are the purchasing agents for 85% of household items. Advertisers and marketers use targeted marketing on Social Media platforms in the hopes of engaging the audience enough to initiate a purchasing action. For this paper the goal was to understand the relationship between women aged 55+ and their attitudes and perception of targeted advertising, to see whether it was effective in engaging them as consumers. Through interviews and the think-aloud method we found that while the overall perception of online advertising was negative, in practice, the ads on their social media feed were either accepted as relevant ads, simply ignored/not noticed, or not recognized as advertising. Finally we conclude that because social media gives users the impression that they are in control of the content on their feed, the consequences may be that targeted advertising can influence audience’s perception of who they are, more than they think.

Testo completoAbstract (sommario):
Alzheimer’s disease (AD) is a major cause of the rapidly growing and crushing aging challenge that threatens to economically undermine today’s healthcare system. AD prevalence will grow to over 100 million cases in 2050. AD is incurable but can be prevented. Therefore, the most viable solution may be to detect very early signs of AD (presymptomatically) in citizens-at-risk and to intervene in time to reduce AD risk or prevent it entirely. The present project will refine and validate two breakthrough innovations for AD detection and AD prevention and commercialize them as a one-stop digital medical device, named ‘AD Detect & Prevent’. The first innovation is a highly sensitive cognitive assessment method recently pioneered by a group of researchers that has been shown to detect subtle presymptomatic stage cognitive decline specific to AD. This will be integrated with the second innovation – a digital AD prevention programme delivered on an award-winning computerized cognitive training and rehabilitation platform (app + web) that uses high intensity immersive and adaptive ‘neurogames’ and audio-based therapy for behavioural intervention, designed for strengthening core cognitive functions, building cognitive reserve, changing lifestyle and thus reducing the overall AD risk in individuals. The detection and prevention methods will undergo vigorous scientific validation, and the ambition is to create and become the global standard of care for precise presymptomatic detection of AD and effective AD prevention.

Testo completoAbstract (sommario):
L’objectif de cette thèse est la gestion de la QdS des systèmes publier/souscrire sur MANET. Ceci provoque un maintien permanent de la connectivité entre les parties communicantes du système. Plus précisément, les contributions de cette thèse, sont organisées autour de deux grands axes relatifs aux modules de monitoring et d’analyse de la QdS de ces systèmes dans un contexte ad-hoc. Ceci englobe les etapes de collecte des paramètres de QdS au cours du fonctionnement du système, et de détection des dégradations pouvant l’affecter.Contrairement à ce qui existe dans la littérature, notre module d’analyse, basé sur des méthodes statistiques, se base sur des seuils adaptatifs qui tiennent en comptes de la dynamicité du réseau et des changements affectant le contexte ad-hoc. En outre, le module d’analyse proposé offre à l’utilisateur une variété de choix entre une analyse réactive, proactive et hybride. Notre module permet aussi une localisation des pannes une fois détectées ou prédites. Des expérimentations menées à l’aide du simulateur Jist/Swans ont montré l’efficacité des modules developpés. De plus, une mesure des paramètres de performance du système avant et après introduction des modules développés a montré leur efficacité. Finalement, une étude de la complexité spatiale et temporelle du module analytique proposé a été réaliséeMobile ad-hoc networks (MANET) is a set of nodes, communicating meaning wireless channel without any centralized control. The main characteristic of MANET is the frequent mobility of its nodes leading to some dynamic changes of topology. Nodes mobility in such networks introduces possible disconnections between adjacent nodes, and more generally quality of service (QoS) degradation issues that do not fit well with QoS requirements of QoS sensitive applications. Publish/subscribe communicating system has been proposed at the middleware layer in order to communicate mobile entities in MANET. Such system is a decoupled interaction between publishers (or producers) and receivers (or consumers).Our goal in this thesis is to provide a QoS management for publish/subscribe systems when deployed on MANET while assuming a best effort flux at the routing layer. This thesis proposes an analytical model for latency aware publish/subscribe systems on mobile ad-hoc networks. The proposed approach combines both proactive and reactive statistical analysis.On the one hand, the reactive analysis, suitable for multimedia applications, detects failures by approximating latency series with Gumbel distribution. On the other hand, the proactive analysis, suitable for crisis management applications, forecasts failures occurrence relying on Auto Regression or Auto Regressive Integrated Moving Average Formulas. Finally, a hybrid analysis was proposed by dynamically switching from reactive to predictive forms of analysis whenever quality of service violations are noticed. In order to extract failure cause, we refer to the correlation method once failure was detected or predicted. Simulations done, using Jist/Swans simulator, under different scenariosproved the efficiency and accuracy of the proposed scheme

Testo completoAbstract (sommario):
Dans un contexte de besoins croissants de moyens de communication pour augmenter la sécurité des vols et répondre aux attentes des compagnies et des passagers, le monde de l’aviation civile cherche de nouveaux systèmes de communication pouvant répondre à ces objectifs. Les systèmes de communication sol-bord existants, que ce soit les solutions par satellites en bande L (SATCOM, ...) ou les solutions cellulaires par liaison directe avec le sol (HF, VHF, ...), présentent des limites en terme de capacité, de couverture et de coût.La proposition avancée dans le cadre de cette thèse est d’utiliser les avions comme relais afin de propager les données jusqu’à une station sol. Ce système peut être vu comme un réseau ad hoc mobile dont les nœuds sont les avions civils en vol. Grâce à plusieurs sauts successifs au travers d’avions relais, chaque avion doit pouvoir joindre le sol sans être à portée directe d’une station. Le réseau ad hoc ainsi formé peut ensuite être utilisé pour différentes classes de communications : contrôle aérien, services pour les compagnies aériennes ou pour les passagers. Une telle solution permettrait d’améliorer la couverture des solutions cellulaires classiques en zone continentale. Elle est également applicable en zone océanique où les seuls moyens disponibles sont actuellement le satellite et la HF. On peut imaginer que les coûts de déploiement et de maintenance seraient relativement bas puisque l’infrastructure sol est limitée.Dans cette thèse, nous avons étudié la faisabilité puis les performances qui peuvent être attendues pour ce système de communication aéronautique innovantIn the current aeronautical communications context, there is an increasing interest in offering new services to civil aircraft. For instance, airlines are looking into new solutions to back up flight data and cockpit voice records during the flight, or to provide more accurate meteorological data to pilots. Being able to offer Internet access to passengers is also a major demand from these companies. All these services represent new types of air-ground communications that require newcommunication systems. Indeed, traditional datalink systems are based on a direct airground link (e.g. VDL Mode 2) or on a satellite link (e.g. L-Band Inmarsat satellites).They all have limits in terms of capacity, coverage and cost. In this thesis, we study aeronautical ad hoc networks. They have recently been proposedas a new solution for future air-ground communications. The idea of such networks is to introduce wireless links between aircraft. This system can be seen as a mobile ad hoc network whose nodes are civil aircraft in flight. Each aircraft is able to act as a router to send data hop-by-hop to the destination. Such a solution would improve the coverage of conventional cellular solutions in continental area. It is also applicable to oceanic areas, where the only available solutions are now satellite and HF. The costs of deployment and maintenance would be relatively low because the ground infrastructure is limited. In this thesis, the feasibility of this innovative aeronautical communication system is investigated. A simulation tool has been developed to study the network connectivity, based on actual aircraft positions data both in continental and oceanic airspace

Målet med detta projekt var att hjälpa IT-Mästaren att kunna fakturera sina kunder på ett smidigare sätt. Deras dåvarande lösning av kundernas dataanvändning var tidskrävande och ineffektivt, därför ville de automatisera systemet. Det nya systemet skulle användas för att administrera kundernas servrar med hjälp av ett grafiskt gränssnitt och sedan kontakta dem för att få fram olika värden för respektive kund som ska presenteras på IT-Mästarens hemsida. På så sätt skulle de kunna fakturera sina kunder på ett mer effektivt sätt och även få bättre överblick av kundernas användning. I och med utvecklingen utav detta system så fördjupande jag mig dels i egna kända områden men jag lärde mig också nya kunskaper. Det gällde inte enbart teknisk utveckling utan också undersökning av exempelvis hämtningen av alla data som skulle göras. Jag använde utvalda metoder för att kunna utföra detta projekt på ett smidigt och bra sätt. Metoderna beskrivs i rapporten.The goal of this project was that the IT-Mästaren wanted to be able to bill their customers in a more comfortable way. Their solution of the customer’s server usage of that time was time consuming and inefficient, therefore they wanted to automate the system. The new system should manage their customer’s servers by using a graphical interface and then contact them to get different values for each customer to be presented at the IT-Mästaren's website. In this way they could bill their customers more efficiently and get a better understanding of their customers’ use. With the development of this system I immersed in my own known areas and I also learned new knowledge. It was not only about technical development but also investigationamong other thingslike retrieval of all the data that should be collected. I used selected methods in order to perform this project in a smooth and effective manner. The methods are described in the report.

Testo completoAbstract (sommario):
Commercial and private cloud providers offer virtualized resources via a set of co-located and dedicated hosts that are exclusively reserved for the purpose of offering a cloud service. While both cloud models appeal to the mass market, there are many cases where outsourcing to a remote platform or procuring an in-house infrastructure may not be ideal or even possible. To offer an attractive alternative, we introduce and develop an ad hoc cloud computing platform to transform spare resource capacity from an infrastructure owner’s locally available, but non-exclusive and unreliable infrastructure, into an overlay cloud platform. The foundation of the ad hoc cloud relies on transferring and instantiating lightweight virtual machines on-demand upon near-optimal hosts while virtual machine checkpoints are distributed in a P2P fashion to other members of the ad hoc cloud. Virtual machines found to be non-operational are restored elsewhere ensuring the continuity of cloud jobs. In this thesis we investigate the feasibility, reliability and performance of ad hoc cloud computing infrastructures. We firstly show that the combination of both volunteer computing and virtualization is the backbone of the ad hoc cloud. We outline the process of virtualizing the volunteer system BOINC to create V-BOINC. V-BOINC distributes virtual machines to volunteer hosts allowing volunteer applications to be executed in the sandbox environment to solve many of the downfalls of BOINC; this however also provides the basis for an ad hoc cloud computing platform to be developed. We detail the challenges of transforming V-BOINC into an ad hoc cloud and outline the transformational process and integrated extensions. These include a BOINC job submission system, cloud job and virtual machine restoration schedulers and a periodic P2P checkpoint distribution component. Furthermore, as current monitoring tools are unable to cope with the dynamic nature of ad hoc clouds, a dynamic infrastructure monitoring and management tool called the Cloudlet Control Monitoring System is developed and presented. We evaluate each of our individual contributions as well as the reliability, performance and overheads associated with an ad hoc cloud deployed on a realistically simulated unreliable infrastructure. We conclude that the ad hoc cloud is not only a feasible concept but also a viable computational alternative that offers high levels of reliability and can at least offer reasonable performance, which at times may exceed the performance of a commercial cloud infrastructure.

Testo completoAbstract (sommario):
In questo elaborato di tesi viene presentata la comparazione tra due codici CFD, rispettivamente Fluent e OpenFOAM, mediante simulazioni che sono alla base di uno studio numerico di flusso attorno ad un pantografo per treno ad alta velocità. Si è apprezzato quindi la facilità d’uso di un software venduto tramite licenza e la difficoltà di un software open source come OpenFOAM, il quale però ha vantaggi in termini di adattamento ai casi più specifici. Sono stati quindi studiati due casi, scambio termico in regime laminare attorno ad un cilindro bidimensionale e flusso turbolento completamente sviluppato in un canale. Tutte le simulazioni numeriche hanno raggiunto convergenza e sono state validate positivamente mediante confronto con dati sperimentali. Il primo caso prevede un cilindro investito da un flusso a temperatura minore rispetto alla temperatura della superficie del cilindro; per avere più riscontri, sono state condotte diverse prove a valori differenti del numero di Prandtl, e per ogni simulazione è stato ricavato il corrispettivo numero di Nusselt, successivamente comparato con i dati sperimentali per la validazione delle prove. A partire dalla creazione della griglia di calcolo, è stato effettuato uno studio del fenomeno in questione, creando così una griglia di calcolo sviluppata a valle del cilindro avente maggior densità di celle a ridosso della parte del cilindro. In aggiunta, svolgendo le prove con schemi numerici sia del primo che del secondo ordine, si è constatata la miglior sensibilità degli schemi numerici del secondo ordine rispetto a quelli del primo ordine. La seconda tipologia di simulazioni consiste in un flusso turbolento completamente sviluppato all’interno di un canale; sono state svolte simulazioni senza e con l’uso delle wall functions, e quindi usate griglie di calcolo differenti per i due tipi di simulazioni, già disponibili per entrambi i software. I dati ottenuti mostrano uno sforzo computazionale maggiore per le simulazioni che non prevedono l’uso delle wall functions, e quindi una maggiore praticità per le simulazioni con le wall functions. Inoltre, le simulazioni di questo secondo caso sono state svolte con diversi modelli di turbolenza; in Fluent sono stati utilizzati i modelli k-ε e RSM mentre in OpenFOAM è stato utilizzato solo il modello k-ε in quanto il modello RSM non è presente. La validazione dei risultati è affidata alla comparazione con i dati sperimentali ricavati da Moser et all mediante simulazioni DNS, mettendo in risalto la minor accuratezza delle equazioni RANS.

Testo completoAbstract (sommario):
There is an urgent need for the development of new therapeutic strategies for Alzheimer's disease (AD). The dual-specificity tyrosine phosphorylation-regulated kinase-1A (Dyrk1a) is a protein kinase that phosphorylates the amyloid precursor protein (APP) and tau and thus represents a link between two key proteins involved in AD pathogenesis. Furthermore, Dyrk1a is upregulated in postmortem human brains, and high levels of Dyrk1a are associated with mental retardation. Here, we sought to determine the effects of Dyrk1 inhibition on AD-like pathology developed by 3xTg-AD mice, a widely used animal model of AD. We dosed 10-month-old 3xTg-AD and nontransgenic (NonTg) mice with a Dyrk1 inhibitor (Dyrk1-inh) or vehicle for eight weeks. During the last three weeks of treatment, we tested the mice in a battery of behavioral tests. The brains were then analyzed for the pathological markers of AD. We found that chronic Dyrk1 inhibition reversed cognitive deficits in 3xTg-AD mice. These effects were associated with a reduction in amyloid-beta (Ab) and tau pathology. Mechanistically, Dyrk1 inhibition reduced APP and insoluble tau phosphorylation. The reduction in APP phosphorylation increased its turnover and decreased Ab levels. These results suggest that targeting Dyrk1 could represent a new viable therapeutic approach for AD.

Testo completoAbstract (sommario):
This essay presents a case study regarding how some preschool teachers describe the diagnosis of AD/HD, and how they express their perception of children who show the symptoms associated with that diagnosis. We also wanted to study how the preschool teachers described their work with these children, and how the teachers responded to the children’s specific needs. The study draws on a qualitative study based on interviews with six preschool teachers in two municipalities in the Southern Stockholm region. All of the teachers had experience of children with an AD/HD diagnosis. Interviews were recorded and transcribed before analysis. The theoretical framework chosen for this essay is discourse analysis. We applied different parts of Fairclough’s and Foucault's methods of discourse analysis to clarify how language was used to describe children with AD/HD. The framework also allowed us to analyse how language may contribute to construct and maintain discourses about children with that diagnosis. We could discern from the interviews with the preschool teachers that children with AD/HD were mainly described as problematic. Another conclusion is that although the teachers showed an awareness of gender issues when speaking of children generally, their choice of words when talking about children with AD/HD implied old stereotypical gender-based expectations. Finally, the preschool teachers described both advantages and disadvantages of diagnosing children, however, most of them emphasised a need for a diagnostic categorization to facilitate their work with these children.

Testo completoAbstract (sommario):
Den här rapporten handlar om Azure AD Connect och Single/Simplified Sign On. Användare och kunder idag ställer större krav för enklare inloggning och en mer sömlös upplevelse för åtkomst till alla IT-tjänster. Microsoft har nyligen släppt verktyget Azure AD Connect för synkronisering av lösenord mellan Active Directory och molntjänsterna Office365, Azure och 1000-tal SaaS ”Software as a service” applikationer. TeamNorr IT-partner är ett IT företag som riktar in sig på att leverera Microsofts produkter till sina kunder och vill därför veta mer kring Azure AD Connect, vad som krävs och hur det konfigureras. Single Sign On har betydelsen att bara behöver logga in en gång för att sen slippa skriva in användare och lösenord för att komma åt de applikationer som har stöd för Single Sign On. Federerad domän är det som ger bäst och säkrast upplevelse med Single Sign On. Simplified Sign On gör att samma användarnamn och lösenord används för inloggning, ingen automatisk inloggning sker. Azure AD Connect är verktyget som installerar de roller som behövs för att köra Single Sign On eller Simplified Sign On. Som standard installeras en synkroniseringsmotor som ska hålla koll på att informationen om användarna/grupperna och lösenorden stämmer mellan det lokala Active Directory och Azure Active Directory eller den federerade domänen. Det synkroniseringsmotorn tar med när den synkroniserar bestäms av de regler som satts upp. Används lösningen med Password Sync så tillkommer inga extra roller. Väljs istället en Federerad domän så installeras 2 extra roller som heter Federation(AD FS) och Web Application Proxy(WAP). Rollerna sköter autentisering av användarna istället för Microsofts autentisering. På servrarna som hostar rollerna krävs en viss grundprestanda beroende på storlek av Active Directory och antal användare anslutna för att det ska fungera tillfredsställande.This report covers Azure AD Connect and Single/Simplified Sign On. Users and customers today places greater demand for easier login method and seamless experience for reaching all services. Microsoft has recently released Azure AD Connect tool to help synchronize passwords between Active Directory and the cloud services Office 365/Azure and 1000s of Software as a service applications. Team Norr IT-partner is an IT company that focuses on delivering Microsoft products to thier customers and therefore wanted to know more about Azure AD Connect. How to configure the solution and what the set requirements are. Single Sign On means that you only need to sign in with password and login once and automatically get access the applications that support the technology without any more credentials. By using a Federated domain users get the best and safest experience with Single Sign On. Simplified Sign On lets users use the same username and password to login with to all applications with support, but no automatic login. Azure AD Connect tool installs the roles that are needed to run a Single Sign On or Simplified Sign On. By default the synchronization engine will keep track of information about the users and groups. Passwords are also synchronized between on-premises Active Directory and Azure Active Directory or federation server. What the Synchronization engine takes is determined by the rules defined. Password Sync does not install any extra server roles. With the Federation path there will be extra roles installed called Federation (AD FS) and Web Application Proxy (WAP). They handle the authentication of users instead of the normal Microsoft authentication. There is some set requirement for the servers that host the roles depending on the size of Active Directory and numbers of users. The servers need a certain base performance for it to work properly.

Thesis, Internationella Handelshögskolan, Jönköping University, IHH, Företagsekonomi, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-48853.
Testo completoAbstract (sommario):
Background: Online marketing tactics designed to have a minimized impact on consumer experience have emerged recently whereas native advertising is one concept. Native advertising is an approach designed to decrease interruptions in consumers’ online experience by matching the form and functions of the platform in which the advertisement appears. It occurs online, with the one characteristic in common that it should not disrupt or negatively affect consumer experience. The desire to minimize consumer disruption has led to that native advertising in its most effective nature can be difficult for the reader to identify, which leads to the discussion of whether the tactic is deceptive. It is found that ad disclosures are frequently the only thing that separates native ads from commercial content. Unexplored areas in the literature exist, which include if native ad disclosures can be made more efficient with the use of brand disclosures. Purpose: The purpose of this thesis is to investigate if brand disclosure in native advertisements affects consumers’ native ad recognition ability. Method: Data was collected through an eye-tracking experiment, exploring if brand disclosures affect the native ad recognition ability. The experiment was created in Tobii Pro Lab which tracked participants’ real-time physiological reactions. Results were complemented with a questionnaire and data was analyzed in SPSS. The sample consisted of 60 students at Jönköping University. Findings: The analysis illustrates that the experimental test group which received brand disclosures of high prominence showed an increased ability to recognize and identify native advertisements as promotional content compared to the control group. By implementing Mann-Whitney U tests and a Chi-Square test in order to test the hypotheses, results were found significant. The hypotheses were supported and could not be rejected, which resulted in the conclusion that brand disclosures increase the native ad recognition ability.

Dando continuità all’attività di ricerca intrapresa durante il mio precedente tirocinio presso il Dipartimento di Ingegneria Industriale DIN di Bologna, lo scopo della mia tesi è stato quello di chiarire i meccanismi di stabilità di fase della lega ad alta entropia CoCrFeMnNi ed esplorare la sua natura metastabile alle medio-alte temperature (tra i 450-1150°C). Nell’ottica di possibili future applicazioni industriali, è stato inoltre valutato l’effetto che la produzione via Additive Manufacturing può avere su proprietà e comportamenti delle leghe ad alta entropia.
Sperimentalmente sono state fatte importanti osservazioni, a volte in contrasto con la letteratura precedente, che aprono la strada ad ulteriori e più specifiche indagini verso la comprensione dei complessi meccanismi che recentemente hanno reso queste leghe così interessanti per la ricerca a livello mondiale.

Testo completoAbstract (sommario):
Flickor med AD/HD upptäcks ofta inte i tid vilket kan ge konsekvenser inom flera områden under uppväxten. Syftet med denna uppsats var att bidra till en ökad förståelse kring hur diagnosen AD/HD kan påverka livet under uppväxten för flickor. Sex vuxna kvinnor med AD/HD intervjuades för denna studies syfte. Studien grundade sig i kvalitativ metod med hjälp av fenomenologisk tolkning samt meningskoncentrering vid sammanställning och analys av intervjumaterialet. Undersökningen fokuserade på sex centrala teman; diagnosens betydelse, skola, fritid, familjen, jämnåriga relationer och självuppfattning. Resultatet förtydligade att dessa centrala teman är betydelsefulla områden för en flicka med AD/HD under uppväxten. Ett fastställande av diagnosen AD/HD spelar en central roll gällande förståelse och hjälp från omgivningen. Studien visade på att flickor med AD/HD har vissa svårigheter i relationer till lärare, jämnåriga samt familj under uppväxten. För majoriteten av respondenterna har mamman varit det viktigaste stödet under uppväxten. Det har framkommit att familj och lärare har svårt att förstå samt att hantera flickor med AD/HD. Flickor med AD/HD har olika grad av svårigheter och tillgångar i skolarbetet samt i vardagen. I studien framgick det att undervisningsformen har betydelse för en flicka med AD/HD. Självuppfattningen hos en flicka med AD/HD kan påverkas av samhällets syn på hur en flicka ska vara. I studien framgick det tydligt att flertalet av respondenterna upplevt sig som en pojkflicka under uppväxten. Studien visade även på förekomst av psykisk ohälsa hos flickor med AD/HD under uppväxten.

Vihervalli, Ulriika. "Deviance and disaster : rationalising sexual morality in Western Christian discourses, AD 390-AD 520". Thesis, Cardiff University, 2017. http://orca.cf.ac.uk/103869/.
Testo completoAbstract (sommario):
This thesis argues that the transition from traditional Roman ideas of sexual behaviour to idealised Christian sexual behaviour was a reactionary process, for which the period from AD 390 to AD 520 offers a crucial key stage. During this era, the Roman West underwent significant socio-political changes, resulting in warfare and violent conflict, which created a pressurised and traumatic environment for people who endured them. In this context, the rhetoric of divine punishment for sinful behaviour was strongly linked with sexual acts, causing ideas on sexual mores to develop. The thesis highlights three key aspects of these developments. Firstly, warfare necessitated changes in Christian doctrines on marriages and rape, resulting from collective and cultural trauma. Secondly, sexually impure acts of incest and prostitution were defiling to the religious collective yet the consequences of these were negotiated on a case-to-case basis, reflecting adaptation. Thirdly, traditional Roman ideas of polygyny and homosexual acts overrode Christian ideas on the same. After discussing these three aspects, this work offers a revised interpretation of Salvian of Marseilles’s De gubernatione Dei to illuminate the purpose of the sexual polemic contained in his work – a task that no existing scholarship has attempted to undertake. Daily realities and conflicts drove discourses on sexual mores forwards, and this thesis outlines how this occurred in practice, arguing that attitudes to sex were deeply rooted in secular contexts and were reactionary in nature. This examination of attitudes to sexual mores reveals a re-moulding of pre-existing Roman cultural norms, rather than a revolutionising Christian overtake. The thesis concludes that the ‘Christianisation’ of late Roman society was a process conditioned by contemporary events and concerns, which contributes to interpretations on the dynamics of cultural change in the late antique era.

Testo completoAbstract (sommario):
This thesis aims to define the supply processes for certain major food items to Rome and its hinterland (specifically grain, olive oil, wine, and garum) using modern supply chain modelling techniques, commencing in the late second century AD and continues until the fifth century AD. Strategic changes occurred during this period with the introduction of water-powered milling technology and accompanying changes to the annona system which provided consumers with bread rather than grain, and added other products such as wine, oil and pork to the annona supply. The reasons for these changes are examined to determine their impact on supply and the administrative changes which occurred concurrently. Evidence from ancient sources, both literary and epigraphic, together with relevant archaeological sources and a range of comparative evidence is used to develop a detailed supply model. By necessity, the model covers a range of populations from 650,000 to 1.2 million to allow the full testing of the supply systems in place in antiquity. The analysis includes the mapping of the control systems used such as warehouse management; port and river traffic co-ordination; quality control mechanisms and administrative structures. The use of modern analytical methods provided a detailed understanding of how the various changes occurred over time, adapting to new technology, and applying productivity improvements as and where possible. It is the core premise of this study that all other authors who have worked on the various aspects of the supply processes have neglected to consider supply chain losses, and have therefore assumed that supply is equal to consumption. This critical omission understates the supply requirements substantially, consequently not allowing the complete testing of key issues such as the potential maximum population level of Rome, the management of the port and river systems, and the timing of the introduction of water-powered milling technology. This thesis studies these losses in detail and attempts to answer these key questions.

Testo completoAbstract (sommario):
Mobile collaborative work is a developing sub-area of Computer Supported Collaborative Work (CSCW). The future of this field will be marked by a significant increase in mobile device usage as a tool for co-workers to cooperate, collaborate and work on a shared workspace in real-time to produce artefacts such as diagrams, text and graphics regardless of their geographical locations. A real-time collaboration editor can utilise a centralised or a replicated architecture. In a centralised architecture, a central server holds the shared document as well as manages the various aspects of the collaboration, such as the document consistency, ordering of updates, resolving conflicts and the session membership. Every user's action needs to be propagated to the central server, and the server will apply it to the document to ensure it results in the intended document state. Alternatively, a decentralised or replicated architecture can be used where there is no central server to store the shared document. Every participating site contains a copy of the shared document (replica) to work on separately. Using this architecture, every user's action needs to be broadcast to all participating sites so each site can update their replicas accordingly. The replicated architecture is attractive for such applications, especially in wireless and ad-hoc networks, since it does not rely on a central server and a user can continue to work on his or her own local document replica even during disconnection period. However, in the absence of a dedicated server, the collaboration is managed by individual devices. This presents challenges to implement collaborative editors in a replicated architecture, especially in a mobile network which is characterised by limited resource reliability and availability. This thesis addresses challenges and requirements to implement group editors in wireless ad-hoc network environments where resources are scarce and the network is significantly less stable and less robust than wired fixed networks. The major contribution of this thesis is a proposed framework that comprises the proposed algorithms and techniques to allow each device to manage the important aspects of collaboration such as document consistency, conflict handling and resolution, session membership and document partitioning. Firstly, the proposed document consistency algorithm ensures the document replicas held by each device are kept consistent despite the concurrent updates by the collaboration participants while taking into account the limited resource of mobile devices and mobile networks. Secondly, the proposed conflict management technique provides users with conflict status and information so that users can handle and resolve conflicts appropriately. Thirdly, the proposed membership management algorithm ensures all participants receive all necessary updates and allows users to join a currently active collaboration session. Fourthly, the proposed document partitioning algorithm provides flexibility for users to work on selected parts of the document and reduces the resource consumption. Finally, a basic implementation of the framework is presented to show how it can support a real time collaboration scenario.

Testo completoAbstract (sommario):
The purpose of the study is to examine different situations and behaviors for students diagnosed with AD / HD and see if there are times where their diagnosis will be extra visible. This will ultimately see how and where these children may need support in their daily lives, and about the support they receive is relevant to their needs. Questions I intend to examine: Are there situations for students throughout the school day in which ADHD diagnosis becomes extra visible? If so, what situations? How is the diagnosis in these situations? It is estimated that about 3-6 percent of school children have AD/HD. It causes difficulties with concentration as well as impulse and activity control. It's not a given that these students get the right support. This is a qualitative study using observations of two children to investigate whether there are situations where students' AD/HD will be extra visible. The results show that there are times when these behaviors clearly manifests during the school day, but also that there are some occasions when some behavior is not particularly noticeable. Some behaviors became evident during the free time during the day, while others became more visible during the controlled period. The result also shows that the times when behaviors are apparent, differs between the two observed the students. This emphasizes the importance to look to the specific needs of support for each individual.

Testo completoAbstract (sommario):
Today, it has become increasingly challenging for firms to communicate with their target audiences, due to the amount of media noise present in the contemporary market. In this study, the author examines how consumers perceive different product settings that are presented within advertisements, and how this affects their attitude toward the ad, with hopes that it will lead to new insights on how the visual element of product setting can be enhanced to create messages that better connect and resonate with consumers in today’s overcrowded market. Using previous literature on Sensory Marketing, Advertising Perception, and Advertising Attitude as basis, a matrix that shows different combinations of product setting was generated, which allowed the author to examine how consumers perceive different typesof product settings. The findings suggest that consumers perceive product settings that aid mental imagery and ads with balanced complexity very positively in their evaluation of advertisements. Ad information, pleasure, and its ability to produce a mental imagery were all found to be keys in garnering positive attitude, and combining these three elements together in one ad has been shown to be the most effective in gathering the highest positive attitude towards the ad. The essay ends by discussing the theoretical and practical implications of these findings, and recommendations for future research.

This master's thesis is focused on the design of a highspeed aquizition system which is based on FPGA and a highspeed AD converter with modern JESD204B interface. Considering the requirements, such as high samplig rate, the current range of available devices is limited. Therefore the market overview of the modern IC and modules was made. The resulting design is based on available modules, so the rached sampling rate is up to 5 GSa/s with 12bits resolution. Data from measurement are send to PC via Ethernet which uses lwIp stack and TEMAC core on Microblaze proccessor.

O presente artigo tem por objetivo caracterizar a acessibilidade para mulheres usuárias de substâncias psicoativas em um CAPS ad a partir da percepção destas e de trabalhadores do serviço. Parte-se da hipótese de que as mulheres que fazem uso abusivo de drogas apresentam especificidades que nem sempre são atendidas pelos serviços de saúde, devido à existência de possíveis barreiras para acessá-los e obter os cuidados necessários. Para tanto, realizou-se um estudo qualitativo, utilizando-se como procedimentos de pesquisa análise documental em prontuários e entrevistas semi-estruturadas. Recorreu-se à análise de conteúdo, com o agrupamento das informações nas seguintes categorias: barreiras socioeconômicas, geográficas, organizacionais e culturais. Os resultados encontrados evidenciaram a ocorrência de todos esses tipos de barreiras, dificultando a obtenção de cuidados de saúde no serviço no qual o estudo foi realizado e sugerindo, dessa forma, fragilidades na acessibilidade ao mesmo. Recomenda-se a realização de outros estudos, considerando-se a incorporação da perspectiva de gênero nos mesmos assim como nas práticas de atenção a usuários de álcool e outras drogas, com o objetivo de repensar e reavaliar estratégias que minimizem as barreiras existentes.

The work deals with the design of novel high order sigma-delta AD converter using switched-capacitors approach. Model of the ideal and real architecture of the third order sigma-delta modulator was designed in MATLAB SIMULINK. The comparison of the ideal and real model of sigma delta architecture is described in this thesis. On the basis of simulation results in MATLAB SIMULINK the stages of modulator on transistors level in CMOS technology were designed. Fully differential operational amplifier, switched capacitor integrator, summing amplifier, comparator, one bit digital to analog converter and nonoverlapping clock generator were designed. The circuit of third order sigma-delta modulator was simulated in CADENCE. Layout of operational amplifier and switched capacitor integrator was made. Through the use of MATLAB was designed decimation filter as well.

Testo completoAbstract (sommario):
Recent developments in nanotechnology have enabled the fabrication of nanomachines with very limited sensing, computation, communication, and action capabilities. The network of communicating nanomachines is envisaged as nanonetworks that are designed to accomplish complex tasks such as drug delivery and health monitoring. For the realization of future nanonetworks, it is essential to develop novel and efficient communication and networking paradigms. In this thesis, the first step towards designing a mobile ad hoc molecular nanonetwork (MAMNET) with electrochemical communication is taken. MAMNET consists of mobile nanomachines and infostations that share nanoscale information using electrochemical communication whenever they have a physical contact with each other. In MAMNET, the intermittent connectivity introduced by the mobility of nanomachines and infostations is a critical issue to be addressed. In this thesis, an analytical framework that incorporates the effect of mobility into the performance of electrochemical communication among nanomachines is presented. Using the analytical model, numerical analysis for the performance evaluation of MAMNET is obtained. Results reveal that MAMNET achieves adequately high throughput performance to enable frontier nanonetwork applications with sufficiently low communication delay.

Testo completoAbstract (sommario):
Through police co-operation, re-admission agreements, and setting up of detention camps, Italy’s immigration policy tries to delocalise border controls between Europe and North Africa. Italian immigration quotas and development aid should induce countries of origin and transit of migrants to tighten their border controls and cooperate with Italy. Development aid is used by the EU in order to exert pressure on other countries, whereas Libya for instance uses transiting refugees as a diplomatic weapon. On the other hand, relations between Italy and North African countries do not focus on human rights violations taking place in some of these countries.

Sharma, Nazuk. "Product Shadows and Ad Evaluations". Scholar Commons, 2017. http://scholarcommons.usf.edu/etd/6950.
Testo completoAbstract (sommario):
Prior research shows that stylistic ad manipulations (i.e., the style or manner in which product visuals are presented in an ad) impact consumer perceptions (Yang, Zhang and Peracchio 2010). This dissertation explores the impact of presence (versus absence) of a product’s shadow in the ad frame, as a visual stylistic manipulation influencing consumer ad perceptions. While many stylistic manipulations have been explored in the past, product shadows in how they impact ad perceptions have not been explored.
Drawing on a holistic understanding on object shadows from the visual art, cognition and psychophysics literature streams, this dissertation investigates how product shadows impact ad perceptions. It applies theoretical tenants of Gestalt psychology, Construal Level Theory (CLT), and information paradigms including Signal Detection Theory (SDT) in deriving seven specific hypotheses. It also tests for moderating factors (such as individual consumer aesthetics, gestalt versus component visual processing modes, and product luxury positioning) that may alter consumer ad evaluations and ad effectiveness perceptions based on this stylistic manipulation of product shadow.
Findings from this dissertation reveal that the presence (vs. absence) of a product’s shadow in an ad frame enhances the product’s visual form. This visual appraisal of the product in the ad frame further improves the ad’s overall evaluations. The effects of a product shadow on ad attitudes is positively moderated by an individual’s aesthetic tendencies (specifically their response tendencies towards visual aesthetics), a gestalt-focused (vs. component-focused) visual processing mode, as well as a luxury based ad’s positioning. There is also some support for negative effects of product shadows in component-focused ad scenarios, where they act as visual impairments rather than enhancers of the product form and aesthetics.
Theoretically, this dissertation extends prior research on stylistic manipulations of product images in visual ad frames, while building upon established ad communication paradigms, including AIDA and Hierarchical Processing Model, HPM (Peracchio and Meyers-Levy 2005; Yang, Zhang and Peracchio 2010). Managerially, findings from this dissertation have implications for print, online, in-store and thus, any form of visual advertising portraying a product form. It outlines specific contexts under which managers can systematically employ (or evade) product shadows to not only enhance ad evaluations, but also to optimize their ad message efficacies.
Stylistic image manipulations comprise production elements (e.g., camera angles), and only affect the way in which the product is displayed, i.e., not the core product image itself (Peracchio and Meyers-Levy 2005; Yang, Zhang and Peracchio 2010). Hence, these can be employed as strategic tools towards ad effectiveness (Barry and Howard 1990). Marketers can not only specifically target and position promotions incorporating product shadows towards aesthetically-attuned consumers, but also save advertising costs by omitting them if their presence hinders the communication of the intended message in certain scenarios.
