Ionic Conductivity in Non-Ionic Compounds
… the ionic conductivities of drugs determined by single surface sensors and parallel plate sensors. The ionic conductivity of various materials at their pre-melt and melt states are studied in order to further study a recently discovered phenomenon. Polar solids like Lidocaine, Ketoconazole, …

The behavior of laterally loaded single piles and group piles in sand
… to investigate the response of laterally loaded single and group piles in sand. A single surface, isotropic hardening constitutive model with nonassociative flow rule is used to model the behavior of sand. The purpose of the study is to gain a better understanding of the soil and pile behavior of …

Studies of Protein Folding on Membranes and in Crowded Environments and Bridging the Research-Teaching Gap in K-12 Science
… and the characterization of membrane binding of single surface and trans-membrane helices. I then describe the effects of excluded volume on the stability and kinetics of a stable Lambda Repressor mutant Y22WQ33YA3749G. Finally, I discuss two education projects that aim to bridge the gap between …

Skinning engineering models with non-uniform, hierarchical B-spline surfaces
… model with non-uniform, hierarchical B-spline surfaces. Non-uniform, hierarchical B-splines offer the mechanical designer many advantages: parametrically defined components may be added to a surface while maintaining C² surface continuity; detailed features may be added to a surface without …

A modal analysis of acoustic propagation in the changing Arctic environment
… the traditional Arctic sound speed profile has a single surface duct, some portions of the Arctic have a sound speed profile which includes a second, lower duct. These double duct systems are seen through out the Beaufort Sea, dating back to 2004, in data made available by the Ice-Tethered …

Shape memory polymer adhesive gripper for pick-and-place applications
… the SMP adhesive gripper interacts with a single surface of a target object for pick-and-place. Furthermore, it is easy and inexpensive to manufacture and applicable to various surfaces since it involves reversible dry adhesion. In this paper, associated physical mechanisms and temperature …

In search of hidden landscapes and new surfaces : fields and filters of architecture
… fields of colors, which are superimposed in a single surface to create an image. Serigraphy is the most vital expressions of contemporary art in Puerto Rico since the 1950s. It represents a vision of a place in its own artificial landscape. The thesis explores the design of a Center for the …

Exploring issues for a cartilage degradation model
… successful in limiting access of ADAMTS to a single surface, as demonstrated by the flat diffusion/degradation front. This led to a good approximation of uni-axial diffusion and fit well with simple mathematical models of diffusion and previously determined diffusivities of Gadolinium agents …

Quantum dynamical study of Si(100) surface-mounted, STM-driven switches at the atomic and molecular scale
… microscope (STM)-controllable, Si(100)(2x1) surface-mounted switches of atomic and molecular scale. The first example considers the switching of single H-atoms between two dangling-bond chemisorption sites on a Si-dimer of the Si(100) surface (Grey et al., 1996). The second system examines …

Impact loading and functional tissue engineering of articular cartilage
… demonstrate that cartilage subjected to a single, non-surface disrupting 1.1 J (Low) impact experiences sufficient degeneration over 4 weeks to become functionally equivalent to tissue subjected to a single, surface disrupting 2.8 J (High) impact. By 24 hrs post High impact, cell death and …

2D and 3D surface image processing algorithms and their applications
… is necessary to obtain a complete 3D model. One single surface representation can better fit to the data. It may be further simplified for rendering, storing and transmitting efficiently, or the representation can be converted to some other formats. This work proposes an efficient algorithm for …

POLARIZATION ABERRATIONS
… The instrumental polarization associated with a single surface is often well approximated as a "parabolic" polarizer. The instrumental polarization function is calculated as a Taylor series Jones matrix about the optical axis as a function of object and pupil coordinates. The resulting spatial …
