In this thesis the temporal and spatial aspects of the low-altitude auroral particle precipitation are investigated using a unique set of particle flux observations from two Defense Meteorological Satellite Program (DMSP) spacecraft in the same orbit but with varying time separation. Three different topics are investigated in this study: auroral stability, the accuracy of the Newell-Meng criteria for region identification, and the relative importance of various magnetopause reconnection models. In the first part the prevalent timescales and spatial dimensions of low-altitude auroral formations are examined using both electron and ion data. It is found that spatial scales larger than 50-100 km are stable for up to 1.5 minutes, while smaller size features vary more rapidly. In the second topic we explore quantitative and qualitative aspects of the Newell-Meng criteria. The flexibility and limitations of the numerical values used are examined with case and statistical studies; all but one are found to be sufficiently robust. Additionally, an expansion of the criteria to include a distinction between open and closed magnetic field line geometries is considered. The last part concentrates on the evaluation of currently proposed models of magnetopause reconnection, based on a case study of ion and electron low-altitude particle reconnection signatures. We conclude that a unique combination of the multiple x-line and bursty single x-line reconnection models is required for a full interpretation of the data. This scenario also provides a comprehensive mechanism for the formation of the low-latitude boundary layer on both open and closed field lines. Finally, the common conclusion of all three studies is that two-point measurements add considerably to our understanding of the low-altitude auroral environment and thereby, the remote processes governing its dynamics. / 2031-01-01

The context of this study is the increasing need for public transport as issues over high private vehicle usage are becoming increasingly obvious. Public transport services need to compete with private transport to improve patronage, and issues with reliability need to be addressed. Bus bunching affects reliability through disruptions to the scheduled headways. The purpose of this study was to collect and analyse data to compare how travel time and dwell time vary, to explore the variation of key variables, and to better understand the sources of these variations. The Orbiter bus service in Christchurch was used as a case study, as it is particularly vulnerable to bus bunching. The dwell time was found to be more variable than travel time. It appeared the Canterbury earthquake had significantly reduced the average speeds for the Orbiter service. In 1964, Newell and Potts described a basic bus bunching theory, which was used as the basis for an Excel bus bunching model. This model allows input variables to vary stochastically. Random values were generated from four specified distributions derived from manually collected data, allowing variance across all bus platforms and buses. However the complexity resulted in stability and difficulty in achieving convergence, so the model was run in single Monte Carlo simulations. The outputs were realistic and showed a higher degree of bunching behaviour than previous models. The model demonstrated bunching phenomena that had not been observed in previous models, including spontaneously un-pairing, overtaking of buses delayed at platforms, and odd-numbered bunches of three buses. Furthermore, the study identified areas of further research for data collection and model development.

In tracing the history of the TIROS meteorological satellite system, this dissertation details the convergence of two communities: the DOD space scientists who established US capability to launch and operate these remote sensing systems and the US Weather Bureau meteorologists who would be the managers and users of satellite data. Between 1946 and 1964, these persons participated in successive coalitions. These coalitions were necessary in part because satellite systems were too big—geographically, fiscally, and technically—to be developed and operated within a single institution. Thus, TIROS technologies and people trace their roots to several research centers—institutions that the USWB and later NASA attempted to coordinate for US R&D. The gradual transfer of persons and hardware from the armed services to the non-military NASA sheds light on the US’s evolution as a Cold War global power, shaped from the “top-down” (by the executive and legislative branches) as well as the “bottom-up” (by military and non-military scientific communities). Through these successive coalitions, actor terms centered on “basic science” or the circulation of atmospheric data were used to help define bureaucratic places (the Upper Atmospheric Rocket Research Panel, International Geophysical Year, NASA, and the World Weather Watch) in which basic research would be supported by sustained and collaboration could take place with international partners.

Suas narrativas têm como características as descrições psicológicas das personagens, as descrições físicas das personagens e dos ambientes, o realismo mágico e a linguagem culta e a coloquial. Além disso, essa obra apresenta a construção de uma representação do espaço latino-americano como uma característica relevante. Este romance foi adaptado para o cinema por Mike Newell, em 2007, com título homônimo. Nesse sentido, trazemos para a discussão a análise da construção do espaço da obra e sua tradução para o cinema, tendo como base os princípios dos Estudos de Tradução e a Transculturação Narrativa. O objetivo principal é analisar a construção do espaço da obra no contexto da literatura e do cinema, considerando aspectos sócio-históricos do processo de criação. Parte-se da ideia de que o filme, mesmo com sua linguagem particular, problematiza questões sobre o espaço da América Latina e consegue dialogar com o universo narrativo do romance de García Márquez. Para isso, realizamos um breve estudo histórico sobre os Estudos de Tradução e sua perspectiva descritiva (TOURY, 1995), para justificar a tradução como fato contextualizado, que leva em consideração o contexto receptor, as decisões do tradutor, ou seja, todo o processo e não só o produto. A pesquisa faz-se descritiva, com abordagem qualitativa, que consiste em uma leitura da obra literária e do filme para analisar a construção do espaço no contexto sócio-histórico da América Latina. Como base teórica, utilizamos os conceitos de reescritura, de Lefevere (2007), e os pressupostos da teoria dos polissistemas, de Even-Zohar (1990); ainda, referenciais teóricos no campo da tradução e da adaptação fílmica, com estudos de Brian Mcfarlane (1996), Robert Stam (2008), Umberto Eco (2007), bem como a análise de estudiosos sobre a literatura moderna e estudos sobre transculturação narrativa, como o de Ángel Rama (1975). / El amor en los tiempos del cólera (1995), de Gabriel García Márquez, presenta rasgos notables del estilo del autor.
