<p>Despite the existence of valuable commentaries on some Classical spring poems, this area of study has been insufficiently explored. After providing a definition and a schema of the spring poem as such, this dissertation investigates, through the detailed analysis of the specific spring poems (Catullus 46; Horace Odes 1. 4, 4. 7, 4. 12; Palatine Anthology 9. 363, 10. l, 2, 4, 5, 6, 14, 15, 16 and Ovid Tristia 3.12), the evolution undergone by this genre from the third century B.C. to the sixth century AD.</p> <p> The Greek spring poems form an obvious group, as their authors follow A.P. 10.1 as a model, employing its schema and some of its elements, while trying to vary and improve on the chronologically earlier poems. Distancing themselves from the Greek tradition, the Latin authors take the genre off in significant new directions, starting new trends and making major changes both in the content and tone of their poems. Defined by their thematic and generic admixture, the Latin spring poems are distinguished by a complexity, depth of thought and variety of form unkown to the Greek tradition.</p> <p>From the spring poems of the Palatine Anthology to Ovid's Tr. 3.12, the genre has known a remarkable evolution. Despite the apparent simplicity of the theme, the authors of the Classical spring poems have reached high levels of sophistication in the way they have succeeded in transforming a relatively straight forward poetic form into a complex and sophisticated genre. Since this series of poems is more than a simple literary parlour game, but constitutes a genre on its own that illustrates, through its major features - stylistic refinement, the use of the Hellenistic techniques of imitatio cum variatione and aemulatio (especially in the Greek tradition, but also in the Latin spring poems) and the blending of literacy and mythological allusions (especially in Horace's spring poems) - typical aspects of Classical poetry, the analysis undertaken in this dissertation gives the Greek and Latin spring poems the critical attention they fully deserve.</p> / Thesis / Doctor of Philosophy (PhD)

This thesis presents research on the feasibility of applying compliant-ortho-planar springs (COPS) to rotational applications. The primary motivation of this research is the application of COPS to a continuously variable transmission (CVT). The design space limitations, loading conditions, stresses, stress concentrations, and limitations of current design tools, such as pseudo-rigid-body models (PRBM) for COPS, are discussed. A new 3D PRBM is presented along with a discussion on the possible applications of such to a rotating COPS. Stress stiffening and lateral stability are two major phenomena occurring in a rotating COPS. Both phenomena are a direct result of the inertial loads a COPS would be subjected to in a rotational environment. The results show how stress stiffening and lateral buckling in the legs are influenced by design parameters. Conclusions and recommendations for further research are recommended.

It is becoming more and more common for developers to build enterprise applications on Spring framework or other other Java frameworks. While the developers are enjoying the convenient implementations of web frameworks, developers should pay attention to con- figuration deployment with metadata usage (i.e., Java annotations and XML deployment descriptors). Different formats of metadata can correspond to each other. Metadata usually exist in multiple files. Maintaining such metadata is challenging and time-consuming. Cur- rent compilers and research tools rarely inspect the XML files, not to say the corresponding relationship between Java annotations and XML files. To help developers ensure the quality of metadata, this work presents a Domain Specific Language, RSL, and its engine, MeEditor. RSL facilitates pattern definition for correct metadata usage. MeEditor can take in specified rules and check Java projects for any rule violations. Developer can define rules with RSL considering the metadata usage. Then, developers can run RSL script with MeEditor. 9 rules were extracted from Spring specification and are written in RSL. To evaluate the effectiveness and correctness of MeEditor, we mined 180 plus 500 open-source projects from Github. To evaluate the effectiveness and usefulness of MeEditor, we conducted our evaluation by taking two steps. First, we evaluated the effec- tiveness of MeEditor by constructing a know ground truth data set. Based on experiments of ground truth data set, MeEditor can identified the metadata misuse. MeEditor detected bug with 94% precision, 94% recall, 94% accuracy. Second, we evaluate the usefulness of MeEditor by applying it to real world projects (total 500 projects). For the latest version of these 500 projects, MeEditor gave 79% precision according to our manual inspection. Then, we applied MeEditor to the version histories of rule-adopted projects, which adopt the rule and is identified as correct project for latest version. MeEditor identified 23 bugs, which later fixed by developers. / Master of Science / It is becoming more and more common for developers to build enterprise applications on Spring framework or other other Java frameworks.

This thesis is concerned with architecture and its changes through four seasons. It is about drawing new images of a building in different seasons. Like trees change their leaves in seasons and like people change their clothes in seasons, this project is about architecture changing its architectural elements in four seasons. It all began with an imagination of how a building would respond differently in each of the four seasons. The project, located at the waterfront of Old Town, Alexandria, Virginia, is an Aquatic Center with swimming pools, changing areas, saunas, fitness area, and massage areas. The Aquatic Center creates different images to its visitors through surrounding natures and their changes, architectural elements and their movements, visitors and their activities. The goal was to provide people unique and different experiences every time they visit. / Master of Architecture

Esta dissertação propõe uma metodologia para a escolha do melhor local para se implantar uma wetland construída. Wetlands Construídas são modelos de ecossistemas projetados pelo homem, especificamente para tratar águas residuais, otimizando processos biológicos, físicos e químicos que ocorrem em sistemas alagados naturais. Proporcionando por sua vez, um tratamento eficaz, econômico e ambientalmente adequado de esgoto. O avanço da informática associado com a Geografia tem gerado o recurso Sistema de Informações Geográficas, e neste se fundamenta este projeto. O SIG, permite que os fundamentos teóricos, conceituais e práticos se mesclem às experiências dos projetistas, trazendo à razão uma base matemática expressa em forma de mapas que podem mostrar as diversas variáveis tratadas em muitas questões relacionadas ao planejamento ambiental racionalizado. Diversos mapas podem ser cruzados pelo SIG, com atribuição de pesos vinculados à importância de cada variável para que, desta forma, possam ser determinadas às regiões do espaço geográfico que melhor atinjam todas as condições estabelecidas, cunhadas como ideais, na implementação de um tipo de intervenção no espaço analisado, como encontrar lugares ideais para implantar sistemas de tratamento de água como wetland construída acompanhado das prerrogativas do Reúso de Água. O lugar escolhido para este projeto de pesquisa foi a Serra do Japi, localizada no município de Jundiaí, situado a aproximadamente 63 quilômetros da capital do Estado de São Paulo, fazendo divisa com os municípios de Cabreúva, Pirapora do Bom Jesus e Cajamar, pertencente a um dos eixos econômicos de maior relevância do país, segundo Morellato (1992). Para o desenvolvimento do projeto, foi estabelecido como condição, que o software utilizado fosse de boa qualidade técnica e também gratuito, para que desta forma outros pesquisadores pudessem facilmente testar e fazer uso da metodologia proposta, sem grandes custos, assim como diversas instituições, como pequenos municípios, ONGs etc. Por este motivo que o software Spring, do INPE Instituto Nacional de Pesquisas Espaciais, foi escolhido. / Não fornecido pela autora.
