Mechanical and Aerospace Engineering Faculty Research & Creative Works

Nanostructured membranes with precisely engineered nanopores were fabricated on a thin silicon nitride membrane, using a combination of bulk micromachining and focused-ion-beam drilling. These membranes are designed to preserve microscale blood channel dimensions, thereby permitting the red cell shape change that enhances gas exchange in the pulmonary capillary. The membranes were tested for their mechanical stability and the results were verified with finite element analysis. Initial studies have proven the membranes to be robust, and capable of withstanding pressures typically experienced in blood oxygenator channels. A novel MEMS-based blood oxygenation system employing the nanoporous membranes is also presented. The oxygenation …

Noise Coupling Between Signal And Power/Ground Nets Due To Signal Vias Transitioning Through Power/Ground Plane Pair, Jun Fan, Matteo Cocchini, Bruce Archambeault, James L. Knighten, James L. Drewniak, Samuel Connor

Electrical and Computer Engineering Faculty Research & Creative Works

Signal vias are often used to move a signal from one PCB layer to another. as a result, these vias can penetrate power/ground plane pair and cause noise coupling (crosstalk) between signal and power/ground nets. This paper studies the noise coupling mechanism using a segmentation approach combined with a via capacitance model and a plane-pair cavity model. Noise coupling from signal to power/ground, and vice versa, is demonstrated in the modeling results.

Introducing Legacy Program Scripting To Molecular Biology Toolkit (Mbt), Todd Newell

Theses

Successful navigating of the ever-changing landscape of molecular visualization programs requires a common thread that can offer users an oasis from the maelstrom of new languages, proprietary applications, and miniscule software life-cycles. Crossapplication scripting remains the benchmark, allowing scientists and researchers to speak a common tongue. The introduction of a new, powerful visualization language, Molecular Biology Toolkit (MBT), has tempted many users to abandon previous methodologies and adopt a new mode of research. MBT, however, is not without drawbacks. Its lack of scripting capabilities creates unmanageable complexity for unsophisticated end-users, namely those without the ability to program. MBT, thus, lacks …

The Viability Of A Thermoelectric Fuel Conditioning System For A Diesel Engine Utilizing Biodiesel, Timothy Schriefer

Theses

Certain internal combustion engines, which run on hydrocarbon fuels, experience difficulty upon engine start-up in extreme cold weather. As ambient temperature decreases below the fuel cloud point and beyond, paraffin form in the fuel and eventually clog the fuel filter causing the engine to fail to start. This problem becomes more pronounced when the engine in question is a Diesel and the fuel utilized is biodiesel. As an alternative fuel source, biodiesel has many advantages; however, its cold weather performance is worse than even conventional diesel fuel. As biodiesel becomes more integrated into the world’s energy usage scenario, one of …

Crash History After Installation Of Traffic Signals (Warranted Vs. Unwarranted), Kenneth R. Agent, Eric R. Green

Kentucky Transportation Center Research Report

The objective of this study was to determine the change in crash history at intersections after installation of a traffic signal. Signals installed based on the warrants from an engineering study resulted in a decrease in angle collisions with an increase in the less severe rear end collisions. At intersections where signal warrants were not met, there was a smaller decrease in angle collisions and a larger increase in rear end collisions. The removal of unwarranted traffic signals did not result in a crash problem. The analysis shows that the warrants given in the MUTCD should be followed when determining …

Stable Pde Solution Methods For Large Multiquadric Shape Parameters, Nicolas Ali Libre, Arezoo Emdadi, Edward J. Kansa, Mohammad Rahimian, Mohammad Shekarchi

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

We present a new method based upon the paper of Volokh and Vilney (2000) that produces highly accurate and stable solutions to very ill-conditioned multiquadric (MQ) radial basis function (RBF) asymmetric collocation methods for partial differential equations (PDEs). We demonstrate that the modified Volokh-Vilney algorithm that we name the improved truncated singular value decomposition (IT-SVD) produces highly accurate and stable numerical solutions for large values of a constant MQ shape parameter, c, that exceeds the critical value of c based upon Gaussian elimination.

Laser Surface Thermal Lensing (Stl): An Optical Method For Surface Analysis Of Glass Transition Effects In Transparent Polymers, Nandita Prasad

Master's Theses and Doctoral Dissertations

Absorption of energy from a modulated laser beam by a transparent substrate leads to cyclic thermal expansion and contraction of the surface at the pump beam focus. This minute distortion of the surface forms a transient optical lens structure, which can be monitored by the changes it induces in a second laser beam reflected at an angle off the same focal point. The Surface Thermal Lensing (STL) technique is based on detecting the modulated interference pattern that results from interaction of the probe beam wavefront as it reflects from both the flat surface surrounding the transient lens and the curved …

Application Of Surface Thermal Lens Technology Combined With Polarization To The Study Of Polymers, Daeha Joung

Master's Theses and Doctoral Dissertations

A new approach was attempted to investigate the characteristics of polymers by using photothermal technology. The Surface Thermal Lens (STL) technique was employed to study polymers because of its higher spatial resolution and greater sensitivity than the classical photothermal detection techniques (PDT). Zeonex [Cyclo-Olefin-Polymer] and acrylic [Poly–Methyl- Meth-Acrylate] were used as the samples. Polarization was applied to the STL technique. The signals of Zeonex were different from those of acrylic when the STL probe beam was polarized. Two different polarizer orientations for the probe beam, crossed and parallel, were used to observe the STL signal response to the samples. No …

Automated Grazing Management, Gregory J. Von Pless

Theses

Management-intensive grazing is a grazing management strategy that relies on careful monitoring of animals at pasture and frequent relocation of animals between various regions of the pasture, or paddocks, in order to maximize the nutrients and sustenance the animals obtain through grazing. When applied successfully, this approach to grazing management yields higher animal production, while cutting feed costs; however, a great deal of overhead is introduced in monitoring and moving the animals throughout the pasture, making this approach very difficult to implement at a large scale. Recent successes in the field of dynamic virtual fencing have demonstrated the feasibility of …

The Manufactured Experience, Debra Ruzinsky

Theses

Repeatedly what I see around me are places and messages that generate manufactured experiences, manipulated by someone with an agenda to promote. My thesis work, entitled "Sweet Reassurance," is a personal approach to re-invention; a conceptually driven body of work that explores my obsession with irony, a need to vent frustration with public policy, complacency, and misguided priorities. The work springs from a notion to create proposals for architectural projects that are rather absurd and could never really be realized. They are my brand of visionary architecture, existing somewhere between the Utopian and the Dystopian. I have developed a vocabulary …

Model Evaluation And Measurement Optimization For The Reproduction Of Artist Paint Surfaces Through Computer Graphics Renderings, Ying Chen

Theses

Light reflection models for computer graphics have been developed over the past several decades. For real paint surfaces, it is possible to model their bidirectional reflectance distribution function with simple models. A framework was established to evaluate two simple reflection models, Phong and Torrance-Sparrow, which were used to render artist paint surfaces under different illumination angles. An image acquisition system was devised to capture the images under selected illuminated angles. The parameters of the specular and the diffuse components were estimated with these image sequences. At the evaluation stage, both physicallybased metrics and psychophysical techniques were used to evaluate the …

Multiple Channel Coherent Amplitude Modulated (Am) Time Division Multiplexing (Tdm) Software Defined Radio (Sdr) Receiver, Veerendra Bhargav Alluri

University of Kentucky Master's Theses

It is often required in communication and navigation systems to be able to receive signals from multiple stations simultaneously. A common practice to do this is to use multiple hardware resources; a different set of resources for each station. In this thesis, a Coherent Amplitude Modulated (AM) receiver system was developed based on Software Defined Radio (SDR) technology enabling reception of multiple signals using hardware resources needed only for one station. The receiver system architecture employs Time Division Multiplexing (TDM) to share the single hardware resource among multiple streams of data. The architecture is designed so that it can be …
