Accelerated Testing of Separation Layers for Open-Graded Drainage Layers
… developed to evaluate performance of separation layers used between open-graded bases and lime stabilized subgrades. Significantly of concern was assessing separation layer performance in regard to the degree of pumping into the open-graded base and the magnitude of deformations occurring during …

Midlatitude sporadic-E layers
… transparent echo from midlatitude sporadic-E layers as recorded by ionosondes; this is the range of frequencies between the blanketing frequency and the maximum frequency. One interpretation is that it is a partial reflection at the steep gradients of electron density which characterize the …

Signal transmission in epithelial layers
… mediated intercellular signaling in epithelial layers, and we study this model under various assumptions. This model is characterized by nonlinear reaction-diffusion type dynamics. The nonlinearities mainly arise at cell layer where feedbacks can be generated through e.g. ligand mediated ligand …

Dissipation in Skewed Boundary Layers
… turbomachines to create highly skewed boundary layers, where the velocity varies in direction as well as magnitude. In this thesis, a combined experimental and high-fidelity computational approach is used to quantify the effect of skew on the dissipation coefficient for the first time. The …

Unsteady boundary layers and separation
The characteristic properties of boundary layer and separation in unsteady flow, play a very important role in fluid and structural mechanics because of their drastic effect on control forces generated by aerodynamic surfaces and loads carried by aerodynamic structures. Prandtl's criterion for …

Secondary instabilities of boundary layers
… of the subharmonic instability of boundary layers are studied. First, the subharmonic instability of incompressible flows over a flat plate is investigated using the resonant triad model and the Floquet model. The primary wave is taken in the form of a two-dimensional (2-0) …

Stability of heated boundary layers
… Blasius, Falkner-Skan and axisymmetric boundary layers. In all the cases considered, heating substantially reduces the n-factors. Results are compared with those of Strazisar & Reshotko (1978) and Nayfeh & El-Hady (1980).

Adsorption of phloretin to lipid layers
… reducing effect of phloretin on mono- and bilayers has been found, it became clear that its primary effect must be a biophysical one: phloretin adsorbs to lipid layers and changes biophysical parameters of these layers. The aim of this work was the characterization of the interaction between …

Multi-Row Film Cooling Boundary Layers
High fidelity measurements are necessary to validate existing and future turbulence models for the purpose of producing the next generation of more efficient gas turbines. The objective of the present study is to conduct several different measurements of multi-row film cooling arrays in order to …

Functional polymer layers with protected amines
This work refers to the area of bio-nanotechnology and concerns the selective immobilization of DNA or other bio-template on microstructured gold contacts and which then permit a coordinated cooperation of several of these nanotemplate, e.g., within a microreactor. The immobilization of such …

Physical phenomena of thin surface layers
… in, or involving thin surface films. Thin surface layers are ubiquitous. Found in nature and used in almost every aspect of daily life, thin surface films are invaluable. While the applications and roles may be varied, to be used effectively, the physical properties of these films and the factors …

Microscopic Physics of Electrical Double Layers
The electrical double layer exists at the phase boundaries of electrolyte solutions, where counterions from solution preferentially accumulate to screen surface charges. Due to the ubiquity of electrolytes, the electrical double layer plays a central role in many fields in science and engineering, …

Augmented reality games : improved data layers
The Scheller Teacher Education Program has been developing Augmented Reality (AR) games software for a number of years. In addition to allowing students to play AR games, the software allows students to create their own games based on a map, a set of characters, and a plot of their choosing. In an …
