abstract: Plagiarism is a huge problem in a learning environment. In programming classes especially, plagiarism can be hard to detect as source codes' appearance can be easily modified without changing the intent through simple formatting changes or refactoring. There are a number of plagiarism detection tools that attempt to encode knowledge about the programming languages they support in order to better detect obscured duplicates. Many such tools do not support a large number of languages because doing so requires too much code and therefore too much maintenance. It is also difficult to add support for new languages because each language is vastly different syntactically. Tools that are more extensible often do so by reducing the features of a language that are encoded and end up closer to text comparison tools than structurally-aware program analysis tools. Kitsune attempts to remedy these issues by tying itself to Antlr, a pre-existing language recognition tool with over 200 currently supported languages. In addition, it provides an interface through which generic manipulations can be applied to the parse tree generated by Antlr. As Kitsune relies on language-agnostic structure modifications, it can be adapted with minimal effort to provide plagiarism detection for new languages. Kitsune has been evaluated for 10 of the languages in the Antlr grammar repository with success and could easily be extended to support all of the grammars currently developed by Antlr or future grammars which are developed as new languages are written. / Dissertation/Thesis / Masters Thesis Software Engineering 2020

Thesis (M. Tech. (Design and Studio Art)) - Central University of Technology, Free State, 2014 / The Information Age has presented those in the discipline of photography with very many advantages. Digital photographers enjoy all the perquisites of convenience while still producing high-quality images. Lecturers find themselves the authorities of increasingly archaic knowledge in a perpetual race to keep up with technology. When inspiration becomes imitation and visual plagiarism occurs, lecturers may find themselves at a loss for taking action as content-based image retrieval systems, like Google™ Search by Image (SBI), have not yet been systematically tested for the detection of visual plagiarism. Currently there exists no efficacious method available to photography lecturers in higher education for detecting visual plagiarism. As such, the aim of this study is to ascertain the most effective uploading methods and precision of the Google™ SBI system which lecturers can use to establish a systematic workflow that will combat visual plagiarism in photography programmes. Images were selected from the Google™ Images database by means of random sampling and uploaded to Google™ SBI to determine if the system can match the images to their Internet source. Each of the images received a black and white conversion, a contrast adjustment and a hue shift to ascertain whether the system can also match altered images. Composite images were compiled to establish whether the system can detect images from the salient feature. Results were recorded and the precision values calculated to determine the system’s success rate and accuracy. The results were favourable and 93.25% of the adjusted images retrieved results with a precision value of 0.96. The composite images had a success rate of 80% when uploaded intact with no dissections and a perfect precision value of 1.00. Google™ SBI can successfully be used by the photography lecturer as a functional visual plagiarism detection system to match images unethically appropriated by students from the Internet.

Percebe-se que o atendimento técnico de boa qualidade pode ser de importância fundamental para o presente momento, considerando-se o rápido desenvolvimento e o surgimento de novas e avançadas tecnologias, o que se torna um desafio cada vez mais constante.

This master thesis examines miniature copies of large-scale paintings as a means of demonstrating knowledge, taste and power at the Saxon court during the reign of Augustus III. In two steps it sheds light on the processes behind the making and collecting of a type of miniature painting that has otherwise been disregarded by art historical research. With the help of five case studies from the Gemäldegalerie Alte Meister in Dresden and a theoretical approach rooted in materiality and contextual studies, it draws the attention of miniature research to the fact that miniature copies were not simple reproductions but the complex results of a multifaceted and prestigious production process. The study thus contributes to a broadened understanding of copies in miniature as valued art objects on their behalf as well as to position them in the larger framework of the 18th century's desire for art, connoisseurship and collecting.

L’étude de l’apprentissage de l’orthographe vise à analyser les mécanismes cognitifs et les structures le rendant possible. Cette acquisition s’effectue au travers de tâches comme la dictée et la copie, utilisées en recherche et à l’école. Si des modèles propres aux tâches rendent compte des processus de la production verbale écrite, ils n’intègrent pas de dimension comparative. L’objectif de cette thèse est d’examiner comment la dictée et la copie participent à cet apprentissage. Le modèle que nous proposons intègre les deux tâches et les instances mémorielles sous-jacentes. Les performances en dictée d’élèves de C.P. et de C.E.1 ont été analysées selon 4 conditions d’entraînement : aucune préparation, lecture à haute voix, lecture à haute voix et copie, copie seule. Les items utilisés sont soit des mots sélectionnés en fonction de leur complexité orthographique et de leur familiarité ou leur fréquence, soit des pseudomots de complexité variable. Globalement les expériences 1, 2, 3 font état d’effets du niveau scolaire et de l’entraînement. Toutefois, dans l’expérience 4, la supériorité de la copie sur la lecture disparaît : la copie ne serait efficace que si elle est combinée à une lecture à haute voix. Si la copie associée au déchiffrage semble l’entraînement le plus efficace en termes d’apprentissages orthographiques, la présence en mémoire à long terme d’une représentation graphomotrice connectée à la représentation lexicale est envisageable. Ceci expliquerait pourquoi, face à un mot que nous lisons mais dont nous doutons de l’orthographe, nous éprouvons le besoin de l’écrire manuellement afin d’en récupérer la forme orthographique normée. / Studies on lexical spelling acquisition have two aims: analyzing the cognitive mechanisms involved in this learning and understanding the processes on which they are based. Dictation and copying are known to be tasks leading to acquire orthographic knowledge. They are used by teachers and researchers. If some specific task models report on cognitive processes involved in verbal written production, they do not allow to get a comparative vision. This thesis aims at examining dictation and copying in the process of lexical orthographic learning. The model we propose includes the two tasks (dictation and copying) and the different underlying memories. We analysed the productions of children of 1st and 2nd grades under dictation according to 4 training conditions: dictation without training, reading aloud, reading aloud and copying, just copying. Children were asked to produce words or pseudowords. Words were selected according to their orthographic complexity and familiarity or their frequency, and pseudowords were more or less complex. Overall, experiments 1, 2 and 3 point out an effect of both grade and training. But, in experiment 4, copying doesn’t seem better than reading aloud: copying could be efficient only when combined with reading aloud. If the association of decoding and copying seems to be the best training to get orthographic knowledge, one might wonder about the presence of a graphomotor representation linked with lexical representation in Long Term Memory. This presence could explain why we need to write a word when we are sceptical about its spelling.

<p>Abstrakt (svenska)</p><p>Bakgrund: Piratkopieringen bara ökar och ökar. Program-, spel- och musikbranschen har idag stora problem. En i stort sett okunnig användare kan fixa en nyutgiven skiva innan den nått butikerna på grund av piratkopieringen. Detta problem möjliggörs genom att ingen bra lösning finns i form av fungerande kopieringsskydd samt att fildelningstjänsterna får stort spelrum. Vi går in specifikt och undersöker musikbranschen.</p><p>Syfte: Fördjupa oss i begreppet piratkopiering. Vidare vill vi upplysa och informera såväl musikbranschen som användare om problemet och dess framtid. Vi hoppas att det resultat vi kommer fram till kan ge underlag för vidare forskning.</p><p>Metod: Vår information har tagits från artiklar på Internet samt från litteratur vi ansett vara aktuell. Telefonintervjuer har skett med Magnus Mårtensson, IFPI (International Federation of the Phonographic Industry), programjuristen Anna Burén på Sveriges Radio, Per Sandin,</p><p>General manager EMI marketing samt ett flertal Internetleverantörer. Vi har dessutom sammanställt en enkät som besvarats av en mängd personer.</p><p>Resultat: Många av gårdagens skivköpare anser att priset för en CD-skiva är för dyrt idag. Man har upptäckt piratkopieringen med dess obegränsade funktioner samt insett hur lätt det är att få tag på gratis musik utan repressalier, vilket beror på den idag vaga och ej alltför avskräckande lagstiftningen. Musikbolagen förlorar pengar och höjer därmed priserna för skivorna samtidigt som de aktivt arbetar för att hitta det perfekta kopieringsskyddet eller för att komma på någon annan strålande lösning.

Software-, game- and music industry are experiencing troubled times at the moment. Today, a practically ignorant person would have no problems to get hold of a newly published record before it reaches the stores because of the</p><p>illegal copying. This problem is made possible due to that no good solution exists. Copy protection isn’t good enough and peer-to-peer-networks are bigger than ever. In this work we will examine specifically the music industry.</p><p>Purpose: We will specialize in the term of illegal copying. Further we want to enlight and inform the music industry as well as the users of the problem and it´s future.

We have also compilated an inquiry which has been replied to by many people.</p><p>Conclusion: Many of the buyers from the past consider the cost of a CD far too high. Instead they have discovered the illegal copying and its unlimited functions. They have also realized how easy you can get new music without reprisals, which mostly depends on the vague and</p><p>not to scary laws. Music companies are losing money and therefore they raise the prize of a single CD, simultaneously as they work to find the perfect copy protection.
