Surface-Texture Fabrication Of Zirconia-Toughened Alumina Using Focused Ion-Beam Machining, Kameron M. Woodruff
Theses and Dissertations
Focused ion-beam machining (FIBM), a precise form of micro-machining, was tested for feasibility in the manufacturing of microscopic dimples in zirconia-toughened alumina (ZTA), a wear resistant ceramic used in artificial joint replacements. The interaction between the ion-beam and the ceramic was characterized in terms of material removal rate (MRR), surface roughness, and notable irregularities (e.g. pitting, steps at vertical faces). These characteristics were used to design and machine patterns of microscopic dimples for tribological testing. The dimple size and pattern area were limited due to a slow MRR and high cost of milling. No significant difference in the coefficient of …

Reconstruction Of Cad Models Into Single Trimmed Surfaces, Rebecca Rasmussen
Reconstruction Of Cad Models Into Single Trimmed Surfaces, Rebecca Rasmussen
Theses and Dissertations
Classical methods by which computer-aided design (CAD) geometries are represented for both design and analysis involve meshing. However, the current process of converting a CAD model into an analysis-suitable surface mesh for the automotive industry takes a significant amount of time and labor, results in a faceted representation of the original smooth geometry, and generates representations that are prohibitively expensive for use in high-order explicit dynamics computations. This research focuses on accurately and efficiently rebuilding given CAD surfaces or meshes, such as shell-like components of automotive vehicles, into smooth, single trimmed spline surface approximations (rather than typical piecewise-linear approximations), making …
Optimizing A Perfusion-Compression Bioreactor Via Python Integration, Umamah Amer
Optimizing A Perfusion-Compression Bioreactor Via Python Integration, Umamah Amer
Honors Theses
Bioreactors are widely used in tissue engineering to support cell and tissue growth under controlled conditions. Perfusion-compression bioreactors, like the one developed in our lab, can be used to replicate the physiological loading of bone on 3D-printed scaffolds. When seeded with osteogenic cells and subjected to mechanical loading, these scaffolds serve as a model to study osteogenesis. To simulate physiological conditions, the bioreactor must apply 1000 compression cycles at forces up to 200 N, three times daily over 14 days. Upon implementation, validation testing and experimental studies exposed several limitations in the bioreactor’s control code. The system was initially programmed …

Assessing The Effectiveness Of Aging Techniques On Cloning Fpga-Based Configurable Ring Oscillator Pufs, Jonathan Thompson
Assessing The Effectiveness Of Aging Techniques On Cloning Fpga-Based Configurable Ring Oscillator Pufs, Jonathan Thompson
Theses and Dissertations
Field Programmable Gate Arrays (FPGAs) are reconfigurable devices that are used in industries that often require increased security. Physically unclonable functions (PUFs) are a security primitive used on FPGAs for device authentication and key generation. However, the output of a PUF can be susceptible to changes in the environment, such as voltage and temperature, as well as changes in device performance that occur due to transistor aging. Previous work has shown that it is possible to induce targeted accelerated aging in order to intentionally change a PUF response, even to the point of cloning one PUF to behave like another. …

An Approach To Model Uncertainty In Fluid Behaviour With Navier-Stokes Equations In Neutrosophic Environment, Muhammad Saeed, Attia Hameed, Neha Andaleeb Khalid, Muhammad Salman Habib
An Approach To Model Uncertainty In Fluid Behaviour With Navier-Stokes Equations In Neutrosophic Environment, Muhammad Saeed, Attia Hameed, Neha Andaleeb Khalid, Muhammad Salman Habib
Neutrosophic Systems with Applications
The complex discipline of fluid dynamics examines the behavior of fluids and their interactions with adjacent objects. The Navier-Stokes equations are very important for explaining how fluids move, but they are not linear and often give answers that depend on the starting point and the boundaries. Modeling fluid behavior is challenging due to the inherently chaotic and unpredictable character of fluid dynamics. To deal with unknown or uncertain values in this research, we used neutrosophic logic to look at the Navier-Stokes equations in a new way. Neosophic logic permits the existence of values that are partially true and partially false; …
