Optimizing limited solar roof access by exergy analysis of solar thermal, photovoltaic, and hybrid photovoltaic thermal systems, Optimizing limited solar roof access by exergy analysis of solar thermal, photovoltaic, and hybrid photovoltaic thermal systems, Abstract: An exergy analysis was performed to compare a conventional 1) two panel photovoltaic solar(More)
—The interface response functions for rapid solidification of a non-dilute binary alloy were measured in the regime of partial solute trapping, where substantial discrepancies exist among predictions for the interfacial undercooling in various models. We used pulsed laser melting of Si-As on insulating substrates to enforce planar solidification spanning(More)
This study provides an in-depth investigation into low-cost and no-cost substrate release mechanisms that allow gas metal arc weld 3-D printed ER4043 aluminum and ER70S-6 steel parts to be removed from a reusable print substrate with minimal energy. Aluminum oxide, boron nitride, and titanium nitride coatings were evaluated as possible substrate release(More)
To provide process optimization of metal fabricating self-replicating rapid prototyper (RepRap) 3-D printers requires a low-cost sensor and data logger system to measure current (I) and voltage (V) of the gas metal arc welders (GMAW). This paper builds on previous open-source hardware development to provide a real-time measurement of welder I-V where the(More)
