Modeling Online Learning Performance with Biometrics: Current Study and Future Directions

Creator:: Sun, Yuzhi and Nembhard, David A.
Abstract:: As the number of students and faculty involved in online learning in recent decades has increased, we recognize that there is a limited understanding of how learners react, interact, behave, and are served by the various components in the information delivery processes. When learning online without an instructor present in...

Investigation of Destratification in Warehouses

Creator:: Polander, Michael D.
Abstract:: A significant source of energy consumption comes from maintaining desired indoor environment conditions in warehouses and other industrial facilities. In efforts to combat the raising energy costs, studies into more efficient heating and cooling strategies has been a topic of consideration for a number of years. One of the areas...

Light soaking in metal-halide perovskites

Creator:: Watts, C. Lowell
Abstract:: Despite climate change requiring the cutback of fossil fuel consumption, the world continues to increase its energy demands each year. To meet the ambitious goals outlined during the Paris Agreement in 2015, which set a goal to limit global warming to 1.5°C [1], changes in energy production methods are necessary....

Selective laser melting and tempering of H13 tool steel for rapid toolingg applications

Creator:: Katancik, Michael, Mirzababei, Saereh, Ghayoor, Milad, and Pasebani, Somayeh
Abstract:: H13 components with a relative density of ∼99% were additively manufactured using the selective laser melting (SLM) process. The highest density part (relevant density 99%) with the lowest level of porosity (<0.01%) was made with a volumetric energy density of 760 J/mm3 (152 W laser power, 100 mm/s scanning speed,...

Oxide dispersion strengthened 304L stainless steel produced by ink jetting and laser powder bed fusion

Creator:: Paul, Brian K., Lee, Kijoon, He, Yujuan, Ghayoor, Milad, Chang, Chih-hung, and Pasebani, Somayeh
Abstract:: This paper discusses the fundamentals of a novel hybrid method to synthesize oxide dispersion strengthened (ODS) 304 L stainless steel (SS) alloy using a modified laser powder bed fusion (LPBF) machine. Previously, ODS metal matrix composites have been produced by LPBF via ball-milling, which is expensive to scale. Here, we selectively...
