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 Thermal Degradation in Structural Alloys for Nuclear Power Systems

Creator:: Teng, Fei
Abstract:: The thermal degradation of structural materials is considered to be a key factor for evaluating the lifetime of current nuclear power plants. Ni-based and Fe-based alloys, such as 690, 625, 304, and 316, are widely used in nuclear industry as structural components due to the extraordinary corrosion resistance and mechanical...

Selective laser melting of 304L stainless steel: Role of volumetric energy density on the microstructure, texture and mechanical properties

Creator:: Ghayoor, Milad, Lee, Kijoon, He, Yujuan, Chang, Chih-hung, Paul, Brian K., and Pasebani, Somayeh
Abstract:: The role of volumetric energy density on the microstructural evolution, texture and mechanical properties of 304L stainless steel parts additively manufactured via selective laser melting process is investigated. 304L is chosen because it is a potential candidate to be used as a matrix in a metal matrix composite with nanoparticles...

Determination of cohesive parameters for aerospace adhesives

Creator:: Hortnagl, Josef G.
Abstract:: The use of adhesives in demanding engineering applications is a very common occurrence in the modern world. These adhesives are taking the role of many traditional fasteners, especially in the area of fiber reinforced composites. As the use of these adhesives become more common place, better understanding of their mechanics...

Additive Manufacturing of FeCrCoCuNi High Entropy Alloy via Laser Powder Bed Fusion and Nickel Aluminum Bronze via Laser Directed Energy Deposition

Creator:: Doyle, Ryan P.
Abstract:: High Entropy Alloys (HEA) exhibit unusual properties and are gaining interest as new materials for challenging applications in the aerospace, hypersonic and medical fields. The application of HEAs have been limited by the development of powder production at scale. A recently developed process of plasma spheroidization by 6K, inc. has...

Growth, Characterization, and Application of Antimony Sulfide Thin Films via a Novel Microreactor Assisted Nanomaterial Deposition for Solid State Batteries

Creator:: Chun, Bryan H.
Abstract:: The continuous development of higher performing battery materials has emerged in parallel with the development of new manufacturing processes. Nanomaterials are one solution to addressing the cycling and performance challenges that limit existing battery cells. However, many of the methods used today for nanomaterial synthesis are high temperature batch methods...

Coevolution and transfer learning in a point-to-point fleet coordination problem

Creator:: Yliniemi, Logan Michael
Abstract:: In this work we present a multiagent Fleet Coordination Problem (FCP). In this formulation, agents seek to minimize the fuel consumed to complete all deliveries while maintaining acceptable on-time delivery performance. Individual vehicles must both (i) bid on the rights to deliver a load of goods from origin to destination...

Determination of Mass Flow Rate through Plain Mesh Wick and Nano- Structured Mesh Wick for the Design of Thermal Compressor Systems

Creator:: Uwaoma, Ifeanyi A.
Abstract:: Wicking action refers to the movement of a liquid through a porous or a structured surface via capillary action. This phenomenon is affected by surface geometry, such as the wick thickness and pore size of the wick, as well as fluid properties, such as viscosity and surface tension of the...

Selective laser melting of austenitic oxide dispersion strengthened steel: Processing, microstructural evolution and strengthening mechanisms

Creator:: Ghayoor, Milad, Lee, Kijoon, He, Yujuan, Chang, Chih-hung, Paul, Brian K., and Pasebani, Somayeh
Abstract:: Oxide dispersion strengthened (ODS) alloys exhibit superior mechanical properties due to the presence of nano-sized thermally stable oxide particles. However, manufacturing of ODS alloys is very complex and composed of numerous time consuming steps such as mechanical alloying, which is one of the main barriers toward the widespread application of...

Nanoparticle-assisted diffusion brazing of metal microchannel arrays : nanoparticle synthesis, deposition, and characterization

Creator:: Eluri, Ravindranadh T.
Abstract:: Microchannel process technology (MPT) offers several advantages to the field of nanomanufacturing: 1) improved process control over very short time intervals owing to shorter diffusional distances; and 2) reduced reactor size due to high surface area to volume ratios and enhanced heat and mass transfer. The objective of this thesis...
