Validation of Design For Additive Manufacturing Heuristics for Aperiodic Structures through Application to Regular Structures

Creator:: Schipper, Paxton
Abstract:: Aperiodic structures cause significant challenges to subtractive manufacturing methods due to the common features such as inaccessible voids within the structure. Additive man- ufacturing presents an appealing alternative for this purpose. The aim of this research is to test analysis heuristics for validity through application to periodic structures. First, a...

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....

Automated Assembly Planning : From CAD Model to Virtual Assembly Process

Creator:: Rafibakhsh, Nima
Abstract:: Assembly planning is a crucial task for every manufacturing product. In general, assembly operations consume more than 30% of the total manufacturing time and cost. Therefore, any effort in optimizing assembly will have a significant impact on the economic success of manufacturing. Finding an optimal assembly plan by hand is...

Potential Additive-Manufacturing of Ablative Thermal Protection Systems

Creator:: Hazell, Kenya K.
Abstract:: Electrodeposition is a versatile polymer deposition technique to create nano-microscale materials using an electrical field generated from a charged droplet of solution and a grounded collector. Electrospinning or electrospraying can occur during electrodeposition, leading to the creation of nanofibers or bead-like materials depending on the process parameters. Photopolymerization of the...

Design Optimization of a Structurally Flexible Wave Energy Converter with a Direct Search Algorithm

Creator:: Berrier, Austin S.
Abstract:: Several wave energy converter designs have been recently proposed that are made of flexible materials. Flexible devices are able to generate electricity by being stretched, and are intended to simplify deployment and maintenance concerns over existing wave energy devices. Due to the relative infancy of flexible wave energy converters, however,...

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...

Learning in Complex Domains : Leveraging Multiple Rewards through Alignment

Creator:: Klinkhammer, Eric R.
Abstract:: In this thesis, we introduce alignment-based algorithms for improving the performance of reinforcement learning solutions for problems where the reward signal cannot be collapsed into a single number. Many real world problems require an agent to balance performance, longevity, and safety, and do so across different timelines. The key to...

Nickel nanoparticles-assisted diffusion brazing of stainless steel 316 for microfluidic applications

Creator:: Tiwari, Santosh K.
Abstract:: Transient liquid-phase diffusion brazing is used in precision, hermetic joining applications as a replacement for diffusion bonding to reduce cycle times, reduce bonding pressure and improve yields. Studies showed that the interlayer used in diffusion brazing can be detrimental due to the use of melting point depressants (MPDs). The goal...
