My work deals with the subconscious pairing of colors from an instinctively chosen color palette into molded forms. My emotions drive these pairings. As I visualize these different emotions, I ask the viewer to formulate their own perceptions and connections (both physical and emotional) in relation to my own. This allows the viewer to explore the emotional twists and turns of my imagination by their own unique associations in correspondence. Painting allows me to visualize the inner depth of my imagination. My work becomes concrete through the subconscious pairing of colors and shapes and evolves with viewer interaction.

No / This paper presents a methodology for efficient shape parametrisation for automatic design optimisation using a partial differential equation (PDE) formulation. It is shown how the choice of an elliptic PDE enables one to define and parametrise geometries corresponding to complex shapes. By using the PDE formulation it is shown how the shape definition and parametrisation can be based on a boundary value approach by which complex shapes can be created and parametrised based on the shape information at the boundaries or the character lines defining the shape. Furthermore, this approach to shape definition allows complex shapes to be parametrised intuitively using a very small set of design parameters.

A measurement of solar neutrinos below 1 MeV of energy will further our knowledge of the neutrino's mass and mixing properties and will provide a probe to possible physics beyond the standard model of particle physics, as well as advance our understanding of energy production in the Sun. Borexino is a liquid scintillator detector that will measure the neutrino energy spectrum to the lowest energy threshold to date. It has been designed to measure the flux of the mono-energetic neutrinos produced by electron capture on 7Be in the Sun's core, which will produce a Compton-like edge in the energy spectrum. Because of the low count rate, Borexino requires extremely low backgrounds, and a good understanding of the backgrounds that do exist. Although the purification techniques used for the scintillator lowered the radioactive contaminates to levels never before achieved, cuts must still be made to the data. At Virginia Tech, we have developed an internal source calibration program that will be able to give us a thorough understanding of both the pulse shape discrimination efficiency and the energy and time response of Borexino. Energy calibration for alphas, betas, and gammas (energy scales) can be accomplished with such sources. When the calibration source is used in conjunction with an accurate source location system any spatial dependencies can be found. The system will use different types of sources at various energies to give the required information to make the cuts needed to extract believable physics from the detector. / Ph. D.
