Automatic Meshing Of Free-Form Deformation Solids, Ssuta S. Hsu

Theses and Dissertations

Development of computer models and subsequent finite element analysis, are important aspects of modern engineering design. In this process, the geometry creation and finite element analysis software are well developed; however, the process of discretizing a geometry into a proper finite element model is time consuming and tedious. The work presented here uses the free-form deformation method to create smooth solid models, and invokes a solid subdivision and transition method to generate the hexahedron finite elements. The combination of these two techniques provides an automatic mesh generator that is easy to use, creates acceptable hexahedron elements for finite element analysis, …

Organ Doses In Routine Radiographic Procedures, Yang Han

Theses and Dissertations

There is general agreement that the extent of the risk from x-ray examination is related in some way to the radiation dose. As the dose increases, the likelihood of significant biological effects also increases. If a clear correlation between dose and effect is to be established, a convenient and reasonably accurate method of estimating patient’s absorbed doses during common radiographic examinations will be highly needed. A simple method is developed in this project to determine the two important parameters e exposure at skin entrance (ESE) and half value layer (IIVL), which is essential to get reasonably accurate estimates of absorbed …

Differences In The. Reading And Mathematics Achievement Between Asian American And Non Asian American Children, Linda B. Price

Theses and Dissertations

Explanations for the achievement or overachievement of Asian Americans are often conflicting and subject to debate among researchers. Four major theories for this achievement are explored in the review of literature. One of these theories concerns the idea that Asian American's beliefs are the result of Confucianism and its influence on the lives of Asian Americans. Another theory examines the parent's positive attitude toward education and its influence on achievement. A third theory suggests that Asian American babies are more alert and sensitive at birth. The final theory examined proposes that the Asian American immigration to the United States is …
