So you want to sell your backyard : an analysis of small-scale detached condominium developments in Austin, TX
(2022-12-02)This report explores small-scale detached condominium regimes in Central Texas. Small-scale refers to 2-unit properties, presented as single family homes with accessory dwelling units (ADUs). These units are commonly sold ... -
Synthesis and characterization of germanium-based nanocrystals
(2021-04-06)Approaches to colloidal synthesis have rapidly developed to control the size, shape, and composition of various semiconductors, offering cost reductions, controllability, and scalability. Of semiconductor materials, germanium ... -
Chronostratigraphy, depositional rates, continental margin progradation, and growth-fault dynamics within the tertiary wedge, San Marcos arch, northwest Gulf of Mexico
(1988)Sedimentation, growth fault slip, and shelf-margin progradation rates were determined for a transect of Tertiary sediments along the axis of the San Marcos arch in the northwestern Gulf of Mexico basin. This low relief ... -
Uniformly speaking : how rhetoric and clothing addresses materiality at work
(2022-12-05)The question guiding this dissertation is: what do we manage with uniformity of clothing? More specifically, how does uniformity of clothing (including actual uniforms) manage our sensing, feeling bodies, our sense of self ... -
Polyphase deformation and metamorphism of the Middle Proterozoic Coal Creek Serpentinite, Gillespie County, Texas
(1989)The Middle Proterozoic Coal Creek Serpentinite and adjacent schists and gneisses of the southeastern Llano Uplift, Gillespie County, Texas, have been multiply deformed under amphibolite facies metamorphism during a ... -

(2023-01-20)The earth is alive -- Realm of lies -- Summer child -- Golden -- To the strongest -- Still remember -- Discord -- Lake of Cod -- What got in the way -- Compassion -
Observations of Binder Jetting Defect Formation Using High-Speed Synchrotron X-Ray Imaging
(2022)The Binder Jetting (BJ) process is capable of producing parts at high speeds from a variety of materials, but performance is limited by defects in the final parts. An improved understanding of fundamental phenomena in ... -
The Failure of Wire-Arc Additive Manufactured Aluminum Alloys with Porosities under Loadings as Observed by In-situ X-Ray Micro-Computed Tomography
(2022)Wire-arc additive manufactured aluminum alloys (WAAM 4043 Aluminum) are widely used in many industries. Porosities are known to exist within the WAAM aluminum alloys, which greatly reduces the usability and reliability ... -
Wire-Arc Additive Manufacturing of Reduced Activation Ferritic Martensitic (RAFM) Steel
(2022)RAFM steel has been considered as the candidate material for an in-vessel component of the fusion wall reactor. Known as F82H in Japan and Eurofer-97 in Europe, RAFM steel is not commercially available. The goal of ... -
Effects Due to Variations in Thermal Properties of Maraging Steel for Finite Element Modeling of the WAAM Process
(2022)Finite element (FE) thermal simulations of the wire arc additive manufacturing (WAAM) process have been widely used to predict the temperature history of as-built parts. Temperature-dependent thermal properties like ... -
Heat Treatment Effects on Mechanical Properties of Wire Arc Additive Manufactured Ti-6Al-4V
(2022)Directed energy deposition (DED) is an attractive additive manufacturing (AM) process for large structural components. The rapid solidification and layer-by-layer process associated with DED results in non-ideal ... -
In-situ Infrared Thermographic Measurement of Powder Properties in Laser Powder Bed Fusion
(2022)The laser powder-bed fusion (LPBF) process is strongly influenced by the characteristics of the powder layer, including its thickness and thermal transport properties. This paper presents an investigation of in-situ ... -
Continuous Sculpting as a Novel Method to Reduce the Staircase Effect in Solidfreeform Fabrication Processes that Are Dependent on Phase Transformation
(2022)Inherent to 2-1/2 axis deposition in Solid Freeform Fabrication is Staircase effect. The surface geometry of parts produced using Solid Freeform Fabrication, therefore is not smooth. Continuous sculpting is a novel ... -
Closed Loop Control Utilizing In-situ Pattern Printing and Reading for Quality Level Determination in Additive Manufacturing
(2022)HP’s Multi Jet Fusion (MJF) is a powder-based technology that selectively melts polymer powder, using a fusing agent, in a layer-by-layer fashion to create 3D parts. One of the challenges for wide adoption of additive ... -
Use of a Fluid Interface to Reduce Support Structures in Top-Down Stereolithography
(2022)Stereolithography (SLA) is a vat photopolymerization additive manufacturing process which utilizes ultraviolet (UV) light energy to cure resin layer-by-layer to build parts. The fabrication of overhanging geometry in ... -
