Many highly developed physical models poorly approximate actual physical systems due to natural random noise. For example, convection in the earth's mantle—a fundamental process for understanding the geochemical makeup of the earth's crust and the geologic history of the earth—exhibits chaotic behavior, so it is difficult to model accurately. In addition, it is impossible to directly measure temperature and fluid viscosity in the mantle, and any indirect measurements are not guaranteed to be highly accurate. Over the last 50 years, mathematicians have developed a rigorous framework for reconciling noisy observations with reasonable physical models, a technique called data assimilation. We apply data assimilation to the problem of mantle convection with the infinite-Prandtl Boussinesq approximation to the Navier-Stokes equations as the model, providing rigorous conditions that guarantee synchronization between the observational system and the model. We validate these rigorous results through numerical simulations powered by a flexible new Python package, Dedalus. This methodology, including the simulation and post-processing code, may be generalized to many other systems. The numerical simulations show that the rigorous synchronization conditions are not sharp; that is, synchronization may occur even when the conditions are not met. These simulations also cast some light on the true relationships between the system parameters that are required in order to achieve synchronization. To conclude, we conduct experiments for two closely related data assimilation problems to further demonstrate the limitations of the rigorous results and to test the flexibility of data assimilation for mantle-like systems.

This thesis examines the use of irony in Joyce’s Portrait, claiming that it has the effect of deconstructing common notions of maturity that are engrained within the Bildungsroman tradition, and that this was Joyce’s intention. In Portrait, irony plays the role of psychological reality, undercutting Stephen’s unrealistic expectation to see his life follow a traditional path of teleological progression. This essay proceeds by looking at the novel’s symbolic, thematic and literary cues, as well as through an analysis of its structure, and Stephen’s psychological and behavioral tendencies throughout the novel. This interpretation of the irony as bearing deconstructive meaning comes from the essay adopting a static, as opposed to a kinetic, apprehension of Stephen in Portrait.

This study is an examination of the beast motif associated with Stephen Dedalus in Joyce's Ulysses. The motif has its origins in Joyce's earlier novel, A Portrait of the Artist as a Young Man. In Ulysses the beast motif is related to Stephen's feelings of guilt and remorse over his mother's death and includes characterizations of Stephen as a fox, a dog, a rat, and a vampire. The motif consistently carries a negative connotation. Several literary sources for the imagery of the beast motif are apparent in Ulysses, including two plays by John Webster, a poem by Matthew Prior, medieval bestiaries, and a traditional Irish folk riddle. The study of the continuity of the beast motif in Ulysses helps to explain the complex characterization of Stephen Dedalus.

In James Joyce’s Ulysses, I believe that Stephen Dedalus enacts a heteroglossic discourse in episode 15, “Circe,” that critiques both English imperialism and the nationalist bourgeois of Ireland. Moreover, Stephen engages not only in an aesthetic and political rebellion through the style of his discourse, but he also engages in the only anticolonial violence in Ulysses against the British soldier Private Carr. Thus, I believe that Stephen separates himself from the ideology of the colonizer and from the bourgeois nationalists through aesthetic, political, and violent means. I will conduct my examination of Stephen as a revolutionary colonial intellectual in three parts using the work of three respective theorists: Mikhail Bakhtin, Frantz Fanon, and Benedict Anderson. Ultimately, I intend to show that Stephen can be read as a gateway through which Joyce represents a new heterogeneous, anticolonial, and antinational community in Ireland. / Department of English

Stephen Dedalus, personagem-conceito assume a escrita do texto e brinca de artífice, dando margem para que o texto trabalhe questões como aspectos de sua criação, uma certa característica de hospitalidade, seus desdobramentos e a reflexão acerca do gênero textual. A hospitalidade derridiana é discutida também sob os olhares da tradução, que se revela enquanto abertura infinda. Nesse ponto o trabalho também discute a relação cíclica texto-leitor-texto e suas leis. A discussão acerca do gênero textual envolve Biografia, Autobiografia, Retrato, Confissão, Diário, Ensaio. Os pactos leitorautor-texto, o pacto e o espaço biográfico. Por fim, as questões da criação conversam com Gilles Deleuze e Félix Guattari sobre o plano da imanência, o da composição e o que mais nos importa do personagem-conceitual que é Stephen Dedalus. _______________________________________________________________________ ABSTRACT / This dissertation addresses issues concerning Joyce’s writing. The conceptual persona Stephen Dedalus undertakes the writing of the text and acts as an artificer, letting the text work issues such as aspects of its creation, a certain trait of hospitality, its consequences and reflections on genre. Derrida’s hospitality, which is also discussed from the standpoint of translation, is revealed as a conceptual opening up. At this point the cyclical text-reader-text relationship and the laws governing it are then discussed. The discussion on genre involves Biography, Autobiography, Portrait, Confession, Diary, Essay; all the possible pacts readerauthor- text, and then the biographical pact and biographical space. Finally, the issues of criation converse with Gilles Deleuze and Félix Guattari on the plane of immanence, composition and what matters most importantly, Stephen Dedalus as a conceptual persona.
