A painting process: a journal

This thesis is presented in journal format and represents a process of painting initiated September 2001 at Louisiana State University. The basis of my paintings can best be described as image oriented mark making. Initially figural images are taken from life drawings then used as starting points to investigate the forms through changes made to their visual properties. Fragments of the images are traced onto paper, manipulated, and then reassembled. This process provides a spring board, a shift from what was recorded earlier by direct observation to images not confined by the requirements of representation

Validation of frequency and mode extraction calculations from time-domain simulations of accelerator cavities

The recently developed frequency extraction algorithm [G.R. Werner and J.R. Cary, J. Comp. Phys. 227, 5200 (2008)] that enables a simple FDTD algorithm to be transformed into an efficient eigenmode solver is applied to a realistic accelerator cavity modeled with embedded boundaries and Richardson extrapolation. Previously, the frequency extraction method was shown to be capable of distinguishing M degenerate modes by running M different simulations and to permit mode extraction with minimal post-processing effort that only requires solving a small eigenvalue problem. Realistic calculations for an accelerator cavity are presented in this work to establish the validity of the method for realistic modeling scenarios and to illustrate the complexities of the computational validation process. The method is found to be able to extract the frequencies with error that is less than a part in 10^5. The corrected experimental and computed values differ by about one parts in 10^$, which is accounted for (in largest part) by machining errors. The extraction of frequencies and modes from accelerator cavities provides engineers and physicists an understanding of potential cavity performance as it depends on shape without incurring manufacture and measurement costs

Privacy in American interiors

Writings on privacy indicated that values placed on the subject vary with the individual, his age, social status, and position in the family. Individual privacy is considered particularly important for children and adolescents. Also, married couples and elderly people need privacy from other family members, particularly children. The value of privacy increases as a person goes up the social ladder. Privacy is recognized as being necessary for maturation and mental development, creativity, and individual well-being. The historical development of housing design revealed that the arrangement and separation of spaces within a dwelling, as well as the sound insulation of certain spaces, promoted or deterred the achievement of privacy. Residential dwellings emphasizing open planning were found to lessen opportunities for individual and family privacy

Refrigeration Plants for the SSCL

The basic requirements and operating features of the collider cryogenic system have already been described in other publications. The general arrangement of the refrigeration plant and its subsystems is presented, and the issue of how to provide redundancy in the cryogenic system is addressed, and some of the basic features of the refrigeration plants are described. The collider cryogenic system design is not final yet, and this report only reflects the direction and current status of the cryogenic system design
