A Fully 3D Printed Waveguide and its Application as Microfluidically Controlled Waveguide Switch
DownloadFall 2016
Hollow rectangular waveguides are employed extensively in microwave and millimeter wave devices owing to their relatively high power handling capabilities and low losses, particularly at higher frequencies, compared to transmission lines. However, the fabrication of such metal waveguides suffer...

A Novel 3D Printed Brace Manufacturing Process for the Treatment of Adolescent Idiopathic Scoliosis
DownloadSpring 2019
Adolescent Idiopathic Scoliosis (AIS) is a three-dimensional spinal deformity with lateral curvature and axial vertebral rotation affecting 1-3% of adolescents. Bracing is a proven non-surgical treatment aiming to stop curve progression. Literature has shown that brace wear time affects brace...

A study on the effect of print parameters on mechanical properties of parts manufactured using additive manufacturing
DownloadFall 2017
This thesis presents an investigation on material-process interaction of vat-photopolymerization processes. The effect of different printing factors on tensile properties is studied. Two vat-photopolymerization processes are considered: Digital Light Processing (DLP) and Stereolithography (SLA)....

Additive Manufacturing of Shape Memory Polymers: Effects of Print Orientation and Infill Percentage on Mechanical and Shape Memory Recovery Properties
DownloadFall 2017
Material Extrusion Additive Manufacturing (MEAM), also known as Fused Deposition Modeling (FDM), is a manufacturing technique in which three-dimensional objects are built. These objects are built by repeatedly extruding thin layers of molten materials through a nozzle in different paths and...

Automated semantic segmentation of NiCrBSi-WC optical microscopy images using convolutional neural networks
Download2022-01-01
Rose, D., Forth, J., Henein, H., Wolfe, T., Qureshi, A.
Convolutional neural networks (CNNs) were used for the semantic segmentation of angular monocrystalline WC from NiCrBSi-WC optical microscopy images. This deep learning approach was able to emulate the laborious task of manual segmentation effectively, with a mean intersection over union (IOU)...

Design and Development of a Novel Tensile Testing Apparatus for Time-Resolved Betatron X-Ray Tomographic Imaging
Download2022-06-01
Arce-Borkent, Alvaro R., Richards, Tait, Senthilkumaran, Vigneshvar, Beier, Nicholas F., Zhou, Le, Moore, John A., Knudsen, K. Steven, Hussein, Amina E., Lipsett, Michael G.
High-resolution imaging of deformation processes in materials under load requires controllable and stable loading conditions and the ability to vary sample orientation relative to the imaging source. A novel tensile testing apparatus has been designed, developed, and characterized for...
