Contudo, curvas e outros obstáculos são comumente encontrados nesse cenário, o que pode afetar a qualidade da medição de vazão em função de perturbações no escoamento, tais como swirl e assimetrias no peril de velocidades. Medidores de vazão por ultrassom de um canal são frequentemente utilizados em instalações de gás de queimadores, apesar de serem sensíveis a tais perturbações. O presente trabalho usa códigos comerciais de CFD para obter o escoamento à jusante de instalações com uma curva e duas curvas, visando a investigar a magnitude e o comportamento de tais efeitos na medição de vazão. Integração numérica é utilizada para diversos arranjos de caminho acústico, simulando medidores de vazão por ultrassom de um canal em várias condições para avaliar o desvio do fator de correção em escoamentos perturbados. Números de Reynolds de 1 x 104 a 2 x 106 são considerados. Ângulos de montagem dos transdutores de 0° a 180° são testados e posições axiais até 80D à jusante do obstáculo são avaliadas. Os resultados indicam que medidores de vazão por ultrassom são sensíveis aos efeitos de acidente de linha. O desvio do fator de correção mostra-se, em geral, consideravelmente maior que 2% em distâncias menores que 20D, conforme recomendado por alguns fabricantes e por leis. Não obstante, tais desvios podem atingir 0,01% em algumas configurações específicas, o que sugere que a medição de vazão por ultrassom pode ser melhorada pelo rearranjo do aparato em posição angular favorável e, principalmente, pela implementação de funções específicas para fatores de correção em condições perturbadas.

The tableau algorithm implemented in the FaCT knowledge representation system decides satisfiability and subsumption in SHIQ, a very expressive description logic providing, e.g., inverse and transitive roles, number restrictions, and general axioms. Intuitively, the algorithm searches for a tree-shaped abstraction of a model. To ensure termination of this algorithm without comprimising correctness, it stops expanding paths in the search tree using a so-called 'double-blocking' condition.

Kant famously claims that autonomy is the ground of dignity. If he is correct about the grounding relationship, then doubts about our autonomy entail doubts about our dignity. Here, I attempt to show that Kant is sensitive to this problem, and invokes the ‘fact of reason’ (Faktum der Vernunft) as the key piece of evidence for our autonomy, and therefore our dignity. But as is well known, Kant’s appeal to the Faktum is controversial. After presenting an exegetical case for the connection between dignity and the fact of reason, I respond to two prominent criticisms of Kant’s strategy in the Critique of Practical Reason in attempt to defend Kant’s use of the Faktum, and hence to preserve his conception of the dignity of humanity.

Limitation as a legal fact Legal institute of limitation has been a part of the legal system since the days of Roman law, yet it is not a legal relic, which in the modern concept of rights had their place. Limitation is a legal institute that is an integral part of modern legislation and whose meaning in law is a proven tradition of more than fifteen hundred years. The aim of this thesis is to give a comprehensive explanation about the institute of limitation in civil law. This thesis divided into five chapters approaches the status of limitation among other legal facts, subjecting it to a thorough analysis, gives the view on the concept of limitation de lege lata and its evolution in our country through historic civil law codification and compares its approach with adjustments in selected European countries. The first chapter discusses general information about legal facts which are divided by traditional keys and on the basis of this division and between them rest the institute of limitation. The second chapter defines the concept of limitation, refers to its meaning, analyzes its components, tests subjects objection of forfeiture accordance with good manners, calculates the rights that are subject to limitation and states that are contrary legislature declared inviolable. This chapter also...

Les créanciers sont la clé de voûte de l’activité de l’entreprise. En cela, ils demeurent le partenaire naturel et primordial de l’exercice de l’activité de l’entreprise. Cette situation est valable indifféremment pour les entreprises in bonis et pour celles qui sont tombées sous le coup d’une procédure collective. Aussi bien en droit français, dans le cadre du livre VI du Code de commerce, qu’en droit de l’OHADA, sous l’impulsion de l’AUPC, les créances postérieures sont celles qui permettent à l’entreprise en difficulté de tenter d’éviter le marasme financier qu’elle rencontre. En effet, les créanciers postérieurs sont ceux qui ont accepté de conclure un partenariat avec l’entreprise en difficulté aux fins de financer la poursuite ou le maintien de l’activité nécessaire à la recherche d’une solution durable. Pour parvenir à comprendre et à analyser le sort des créances postérieures dans les deux systèmes juridiques objet de l’étude, il a fallu répondre à deux questions principales dotées d’une technicité certaine à savoir, d’une part, ce qu’est une créance postérieure et d’autre part, la manière dont elle est traitée par le droit des entreprises en difficulté. La réponse à ces deux questionnements a permis de faire ressortir les ressemblances et les divergences entre le droit français et le droit de l’OHADA quant au sort des créances nées du partenariat postérieur au jugement d’ouverture de la procédure collective. / Creditors are the keystone of the firm’s activity. Indeed, they are still being the natural and primordial partner of the firm’s activity. This situation is valid similarly for in bonis Firms and for those which fell out bankrupt. According to French law, in the 6th book of the commercial law, and Organization for Harmonization of Business Law in Africa (OHADA)’s system, at the instigation of the uniform act on bankruptcy (AUPC), posterior creditors are those who enable ailing firm to eliminate financial stagnation. In the same time, posterior creditors are those who accepted to finalize a partnership with the firm in trouble, instead of its difficulties, so as to finance activity’s pursuit or to support to gain a sustainable solution. To understand and to analyze the fate of posterior creditor in both studying legal systems, it has been necessary to answer two main questions endowed with a certain technical nature. Firstly, what is a posterior debt? And secondly, how are posterior creditors treated by bankruptcy law? Answering to those questions took out likenesses and divergences between French law and OHADA’s system as for the fate of posterior debt born in the later partnership establishes subsequently to the judgment of opening of bankruptcy.

To combat fake news, researchers mostly focused on detecting fake news and journalists built and maintained fact-checking sites (e.g., Snopes.com and Politifact.com). However, fake news dissemination has been greatly promoted by social media sites, and these fact-checking sites have not been fully utilized. To overcome these problems and complement existing methods against fake news, in this thesis, we propose a deep-learning based fact-checking URL recommender system to mitigate impact of fake news in social media sites such as Twitter and Facebook. In particular, our proposed framework consists of a multi-relational attentive module and a heterogeneous graph attention network to learn complex/semantic relationship between user-URL pairs, user-user pairs, and URL-URL pairs. Extensive experiments on a real-world dataset show that our proposed framework outperforms seven state-of-the-art recommendation models, achieving at least 3~5.3% improvement.

Motivation: When I set out to write a novel about Shakespeare’s Dark Lady, I wanted the focus to be on her, not the Bard. However, as I developed the idea, I realised that his character was an essential component of the narrative. So how should I set about ‘inventing’ such an iconic character? In addition, how relevant were earlier versions – biographical and fictional – to this project? Though I found a wealth of material about Shakespeare and his plays, I discovered there is a substantial sub-genre of Shakespeare invention. As a writer new to historical fiction, this felt a little like putting Jesus Christ into a story – and it turned out that some writers have given Shakespeare a distinctly Messianic character. Methods: In order to invent my own version of Shakespeare, I needed to assimilate what had gone before. The line between fact and fiction was blurred, but I clarified what was known and what unknown, and established what was myth. I then researched fourteen fictional versions of Shakespeare, starting with Kenilworth (Sir Walter Scott, Constable & Co, 1821) and ending with Shakespeare’s Memory (Jorge Luis Borges, Penguin, 2001). Results: My discovery was that the invention of history is a complex imaginative and intellectual process, but each writer solves a succession of challenges in their own way. Identifying these challenges helped me to create a new Shakespeare, and to clarify my own reasons for writing this particular novel. Conclusions: Far from being a form which is nostalgic, escapist or conservative, historical fiction is continually re-inventing itself in the light of the events and ideas which are contemporary to the writer. The continuing evolution and re-acquisition of the character of William Shakespeare is an illustration of its perennial significance.

abstract: Do fact-checks influence individuals' attitudes and evaluations of political candidates and campaign messages? This dissertation examines the influence of fact-checks on citizens' evaluations of political candidates. Using an original content analysis, I determine who conducts fact-checks of candidates for political office, who is being fact-checked, and how fact-checkers rate political candidates' level of truthfulness. Additionally, I employ three experiments to evaluate the impact of fact-checks source and message cues on voters' evaluations of candidates for political office. / Dissertation/Thesis / Doctoral Dissertation Political Science 2015
