The experimental part was carried out at MSR Engines s.r.o. This part describes the current (sodium modification) and newly proposed (strontium modification) state of preparation and metallurgical processing of melt. There is state the course of experimental melting processes, testing of samples, evaluation of tests and observation of the impact of individual modifiers on the structure.

The diploma thesis deals with the selection of an eligible supercharger for cooperation with the internal combustion SI engine Honda K20A2. The first part is dedicated to the research referring to an issue of charging and a brief description of particular supercharger types. However, the main part of the thesis consists in the formation of proposal calculation and the tentative choice of the eligible type of supercharger. The part of the work is also the description of the assigned engine and the measurement of its parameters. The most extensive part of the thesis deals with the making of computational model of the atmospheric and supercharged version of the engine and the consecutive simulations in the GT-Power software. Finally, gained results are evaluated and the computational study of the cooperation of the selected supercharger with assigned combustion engine is made in the last part of the diploma thesis.

To increase of bearing steels properties are research and development of surface modifications well above dedicated, in present. Basic requirements to the surface modifications are high wear resistance and good temperature resistance (origin by friction). Surface modifications can not negatively influence properties of bearing steels as a substrate. One of the possibilities can be used surface modifications used for high temperature applications. These are based on saturation of substrate surface layer by Al (and Si) elements. This work deals with preparing of Al and Al-Si diffusion layers from slurries on 100Cr6 bearing steel surface and study of elements interaction between coating and bearing steel as a substrate during proceeding of protective layers at high temperatures. To elements interaction study light microscopy, scanning electron microscopy equipped by energy dispersive microanalyses, glow discharge optical emission spectrometry and microhardness measurement methods were used. To the evaluation of layer thickness image analyses was used.

This thesis examines the influence of inoculation and modification on the internal structure and properties of aluminium-silicon alloys. The effect of inoculation by titanium and boron and modification by sodium and strontium is investigated in experimental part of the thesis. All these metallurgical interventions in the melt are tested on three types of hypoeutectic Al-Si alloys (AlSi10Mg(a), AlSi8Cu3, AlSi7Mg0,3). The experiment was carried out in cooperation with the foundry of non-ferrous metals, Aluminium Group, a.s. in Sloup.

Orientador: Pedro Angelo Pagni / Resumo: Esta tese é uma investigação transversal entre os campos da Educação, da Filosofia e da Magia. O percurso singular de minha existência, aliado à percepção da emergência de saberes e práticas da magia enquanto possibilidade de resistência à biopolítica e ao neoliberalismo na atualidade, possibilitou enunciar a problemática de pesquisa nos seguintes termos: Como a relação entre filosofia e magia permite experimentarmos outra educação filosófica no tempo presente? O meu objetivo geral é desenvolver usos aproximados entre magia e filosofia que problematizem práticas vigentes em nossa formação acadêmica em filosofia. Experimento a hipótese de que tornar visível a ética do cuidado de si em sua dimensão arcaica – cronologia emergente da filosofia ocidental - permite uma integração ao campo da magia como possibilidade de ensaiar um tipo de educação filosófica que amplia o conjunto de técnicas de si para além do pensamento crítico e do humanismo como paradigma epistemológico e disciplinar que nos subjetiva atualmente. Penso o cuidado de si enredado a dois conceitos-chave que a ele se relacionam no período arcaico: o daimon e os sonhos. A especificidade de meu objeto convida Michel Foucault como o principal referencial teórico de tese, mas exige que eu pense com e para além dele. Tal movimento incorre por quatro objetivos específicos, sintetizados como capítulos de tese: (1) Ensaio uma anarqueologia como procedimento e atitude de pesquisa, mostrando certa interface (in)desejável entre ...

The singular path of my existence, combined with the perception of the emergence of knowledge and practices of magic as a possibility of resistance to biopolitics and neoliberalism today, supported the research problem in the following terms: How does the relationship between philosophy and magic allow us to experience another philosophical education at the present time? My general objective is to develop bordering uses between magic and philosophy that problematize prevailing practices in our academic formation in philosophy. I experiment with the hypothesis that making the ethics of care of the self visible in its archaic dimension - an emerging chronology of Western philosophy - allows integration into the field of magic as a possibility to rehearse a type of philosophical education that expands the set of self-techniques beyond critical thinking and humanism as an epistemological and disciplinary paradigm that currently subjective us. I think of care of the self tied to two key concepts that relate to it in the archaic period: the daimon and dreams. The specificity of my object invites Michel Foucault as the main theoretical framework of the thesis, but it requires me to think with and beyond him. This movement arises from four specific objectives, synthesized as thesis chapters: (1) I rehearse an anarcheology as a research procedure and attitude, showing certain (un)desirable...

This thesis first introduces the basic notions of univariate survival analysis. Then the survival analysis setting is extended to competing risk models, i.e. the cases considering several events of interest or several causes of one event. In the competing risk model, we discuss the problem of identification, which means that it is not possible to identify marginal distributions from observed competing risk data. Next, we present copula models, which are a suitable mathematical tool for modelling dependence structure between random variables. We explain their basic characteristics, present some useful copula families and the relationship of copula parameters with certain dependence (correlation) measures. Further, we show the utilization of copulas within competing risks models and how they can be helpful in the solution of identifiability problem. Finally, we apply the listed theoretical knowledge in a simulated example. Powered by TCPDF (www.tcpdf.org)

The thesis presents fundamental characteristics of survival analysis in the case of competing risks and their relationships. In the case without regression, basic nonparametric estimates and a logarithmic likelihood function for parameter estimates is given. The main focus is on Cox's proportional hazards model (PH), a model with accelerated time (AFT) and a flexible regression model (FG) are also mentioned. The identifiability of the associated survival function is solved using copulas. Basics of copula theory and the measurement of dependence by correlation coefficients (Pearson, Spearman and Kendal) are described in a separate chapter. A substantial part of the theory is practically used in a generated case without regression.

[pt] Gustavo Dahl (1938-2011), conhecido principalmente pelo seu trabalho de gestor nas duas principais instituições de cinema no Brasil: a Embrafilme (1975- 1979) e a Ancine (2002-2006), começou sua carreira como crítico de jornal e depois cineasta. Este trabalho debruça-se sobre os anos iniciais dessa trajetória quando o então jovem estudante, convidado por Paulo Emílio Sales Gomes, publica o primeiro artigo para o Suplemento Literário do jornal O Estado de S. Paulo (1958 -1961) e estende-se pelo período de estudos de cinema na Europa (1960-1964). Como método, privilegia-se a análise dos artigos e as correspondências do período europeu, quando Dahl teve por interlocutores: Paulo Emílio, Glauber Rocha, Paulo César Saraceni e Joaquim Pedro de Andrade. Na análise dos artigos observou-se o processo de aproximação do jovem crítico paulista com os jovens bossa novíssimos, nome que Glauber Rocha utilizou para nomear o grupo de diretores cujos primeiros filmes deram origem ao movimento. Na análise das cartas foi possível um entendimento mais alargado das relações entre Dahl e os jovens diretores de modo a ressaltar as diversas fases desse processo de aproximação, da desconfiança inicial para a profunda cumplicidade na defesa do novo cinema brasileiro. Por esta intersecção, foi possível apreender a atuação estratégica de Dahl na origem do Cinema Novo. Em jogo, o desejo de modernização do cinema brasileiro e sua inserção nas vanguardas artísticas da década de 1960, em consonância com os jovens cinemas do período: a nouvelle vague francesa, o cinema independente americano e o cinema revolucionário cubano. / [en] Gustavo Dahl (1938-2011), known mainly for his managerial work at the two major Brazilian film institutions: Embrafilme (1975-1979) and Ancine (2002- 2006), began his career as a film critic in newspapers and then became a filmmaker. This work focuses on the early years of this trajectory when the then young student, invited by Paulo Emílio Sales Gomes, publishes the first article for the Literary Supplement of the newspaper O Estado de S. Paulo (1958 -1961) and extends for the period of film studies in Europe (1960-1964). As a method, the analysis of articles and correspondence of the European period is favored, when Dahl had as interlocutors Paulo Emílio, Glauber Rocha, Paulo César Saraceni and Joaquim Pedro de Andrade. In the analysis of the articles, we observed the process of approaching the young São Paulo critic with the Young bossa novissimos, as Glauber Rocha used to name the group of directors whose first films gave rise to the movement. In the analysis of the letters it was possible to have a broader understanding of the relationship among Dahl and the young directors in order to emphasize the different phases of this process of approximation, from initial mistrust to deep complicity in the defense of the new Brazilian cinema. Through this intersection, it was possible to apprehend Dahl s strategic performance at the origin of Cinema Novo. At stake was the desire for the modernization of Brazilian cinema and its insertion in the artistic avant-garde of the 1960s, in consonance with the young cinemas of the period: the French nouvelle vague, the American independent cinema and the Cuban revolutionary cinema.

Kateřina Skořepová Předmětnost a procesualita hry, Praha 2018 ANNOTATION The idea of a game as a limited space used mainly for fun, leisure or a purposeful instrument is quite limited. From this definition of the vast phenomena of games and play, it is impossible to recognize what else playfulness can offer. By differentiating the subject of the game from the gaming process itself, allows perceiving the general concept of game in a new light. Such a deviation from the generally accepted interpretation of what game is and what playing is, enables the perception of playfulness as a principle in the same way as Greek and modern philosophers described the principle of being. Utilizing this new view we can change the perception of values in everyday life and transform the way we perceive own being. KEY WORDS Game, play, processuality, paidia, world, being
