    CFD study of section characteristics of Formula Mazda race car wings

    Full text link
    A great deal of research has been performed on the aerodynamic characteristics of race cars competing in the major racing series through out the world. Because of the competitive nature of motorsports, this research is usually not published until after it is obsolete. The teams operating at the minor league levels of the sport do not have the funding resources of the major series to perform aerodynamic research; In an effort to provide some information for teams competing in the minor league Formula Mazda race car class, this study was conducted. The Star-CD computation fluid dynamics code was used to perform a laminar simulation on the front and rear wings of a Formula Mazda with different angles of attack and Gurney flap heights. Results are presented graphically showing pressure and velocity distributions

    Le métier d’enseignant universitaire s’apprend le plus souvent « sur le tas » (Knight, Tait et Yorke, 2006). Que recouvre précisément cet apprentissage « sur le tas » ? Cet article vise à répondre à cette question en identifiant les pratiques d’apprentissage que les universitaires novices mettent en œuvre pour construire leurs compétences en enseignement. Dans ce but, en 2016, un questionnaire administré à 376 maîtres de conférences en France a permis de relever que les pratiques d’apprentissage de ces derniers sont éclectiques et tendanciellement non-structurées. Ces pratiques pourraient traduire une aspiration à l’autonomie, c’est-à-dire la capacité à prendre en charge la responsabilité de la construction de leurs compétences d’enseignement leur apprentissage à l’enseignement. À l’heure où la formation pédagogique des enseignants-chercheurs de l’université en France relève d’une obligation statutaire (Le Journal officiel de la République française, 2017), les résultats de cette recherche engagent à une réflexion sur une formation pédagogique des universitaires qui prendrait en compte la diversité des pratiques et l’aspiration des novices à l’autonomie.How to teach in academia is most often learnt on-the-job (Knight, Tait et Yorke, 2006). But what does the phrase “on-the-job learning” genuinely mean in this case? This article aims to identify which learning practices novice academics make use of to acquire their teaching competences in France. In 2016 a survey carried out among 376 novice lecturers showed that novices’ practices are eclectic and mainly informal. These practices are the reflection of the academic novices’ wish to be autonomous. While public authorities have been developing formal training structures targeted at all newly-hired academics (Le Journal officiel de la République française, 2017), this research suggests that the variety of practices should be taken into account

    Actors in a "Cheap Comedy": Dissidents in Soviet Psychiatric Hospitals, 1968-1974

    Get PDF
    This paper examines the Soviet government's hospitalization of political dissidents diagnosed with mental disorders between 1968 and 1974. Relying primarily on memoir accounts produced by the victims of Soviet punitive psychiatry, the purpose of this paper is to explicate the purpose, function, and effectiveness of the Soviet program of committing dissidents to psychiatric institutions. It concludes that this program served primarily to control behavior, rather than suppress ideas or counter-ideologies, embarrassing to the Soviet government. Furthermore, it suggest that in many cases committing dissidents to mental hospitals served the state as a means of negotiating with dissidents and reaching an agreement on what constitutes acceptable behavior, instead of functioning simply as a way to remove them from general society. This paper also argues that some dissidents possessed means of pressuring the state, and that the dialogue between political malcontents and government authorities was not a one sided conversation.Master of Art

    La escritura y el fuera de sí

    Get PDF
    Este texto, nacido de una serie de imposibles, buscará ser un sistema móvil y provisorio de anotaciones en torno a la noción de escritura y sus relaciones con un modo discursivo formulado bajo la égida de un “fuera de sí”. Intentaremos esbozar fragmentos de lecturas, sin perder de vista el contexto en que cada uno de ellos se inserta, y pensar, sobre todo, enlas transformaciones sufridas por esa noción en el pensamiento de los últimos 50 años.Fil: Kiffer, Ana.

    A estesia do pensamento

    Using an introduction to the work and the trajectory of the French writer Antonin Artaud (1896-1948), this paper intends to question the manner the poet’s writingdeals with some long-held notions of the Western culture, such as: body, mind, sensitivity and intellect. Focused on what the poet called “broken language” and “erosion of though” will be possible to understand the relations between this work with preconceived notions of aesthetics and thought.Neste artigo proponho, por meio de uma introdução à obra e ao percurso do escritor francês Antonin Artaud (1896-1948), interrogar de que maneira a escrita do poeta problematiza determinadas noções consolidadas pela cultura ocidental, tais como: corpo, espírito, sensível e intelectivo. Atentos ao que o poeta nomeia ser linguagem partida e a erosão do pensamento, é que se poderão entender as relações dessa obra com as noções constituídas de estética e pensamento

    Ethereum's Proposer-Builder Separation: Promises and Realities

    Full text link
    With Ethereum's transition from Proof-of-Work to Proof-of-Stake in September 2022 came another paradigm shift, the Proposer-Builder Separation (PBS) scheme. PBS was introduced to decouple the roles of selecting and ordering transactions in a block (i.e., the builder), from those validating its contents and proposing the block to the network as the new head of the blockchain (i.e., the proposer). In this landscape, proposers are the validators in the Proof-of-Stake consensus protocol who validate and secure the network, while now relying on specialized block builders for creating blocks with the most value (e.g., transaction fees) for the proposer. Additionally, relays play a crucial new role in this ecosystem, acting as mediators between builders and proposers, being entrusted with the responsibility of transmitting the most lucrative blocks from the builders to the proposers. PBS is currently an opt-in protocol (i.e., a proposer can still opt-out and build their own blocks). In this work, we study it's adoption and show that the current PBS landscape exhibits significant centralization amongst the builders and relays. We further explore whether PBS effectively achieves its intended objectives of enabling hobbyist validators to maximize block profitability and preventing censorship. Our findings reveal that although PBS grants all validators the same opportunity to access optimized and competitive blocks, it tends to stimulate censorship rather than reduce it. Additionally, our analysis demonstrates that relays do not consistently uphold their commitments and may prove unreliable. Specifically, there are instances where proposers do not receive the complete value as initially promised, and the censorship or filtering capabilities pledged by the relay exhibit significant gaps

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Jurídicas. Programa de Pós-Graduação em DireitoBusca-se verificar se o princípio constitucional da individualização da pena de privação de liberdade aplicado aos condenados por tráfico de drogas permite ao operador jurídico a substituição da pena de prisão por outros tipos de apenamentos, visando evitar o encarceramento, uma vez que a prisão não é instrumento apto para assegurar as finalidades que são atribuídas, na atualidade, à pena: retribuição, intimidação, ressocialização e incapacitação do condenado
