Numerical Modeling of Powder Metallurgy Hot Isostatic Pressing

Creator:: Sobhani, Samaneh
Abstract:: Powder Metallurgy Hot Isostatic Pressing (PM-HIP) is a widely recognized powder metallurgy manufacturing process to produce near-net-shape and net-shape components. During general PM-HIP processes the metal powders are filled within a capsule (die), heated and loaded with high pressure simultaneously, and solidified to form the final product. Due to the...

Utilizing smart manufacturing information in a job shop to support job selection and processing speed decisions

Creator:: Houck, Christopher
Abstract:: Creating schedules for the job shop manufacturing system is an extremely difficult task. Although researchers have devoted a lot of attention to generating optimal solutions, these solutions are static, thus they do not update as random events occur that disrupt the system. As smart manufacturing has grown, researchers have been...

Synthetic Lubricant Performance in Enclosed Gearbox Applications at Extreme Temperature

Creator:: Marr, Carter J.
Abstract:: The goal of this paper is to evaluate how synthetic lubricants perform in an enclosed gearbox application when compared with a proven mineral oil. This is in an effort to improve gearbox efficiency with the desired effect of lower emissions from of improved energy output from power generation. Four liquid...

The role of material properties in an ISBM process to manufacture polypropylene bottles from virgin and PCR resins

Creator:: Chen, Cheng-Ting
Abstract:: Post-Consumer Recycled (PCR) resin grades have been successfully incorporated into plastic ink supply cartridges, with 80% of cartridge products containing 45% to 70% recycled polyethylene terephthalate (rPET). With this tremendously successful experience, incorporation of recycled polypropylene (rPP) into Injection Stretch Blow Molding (ISBM) bottles has been attempted to increase sustainability...

Environmental Sustainability During the Early Design Phase: Understanding the Uncertainty in the Use Phase, Visualization, and Automating Design Repository Curation

Creator:: Tensa, Melissa
Abstract:: The objective of this research is to support DfX considerations in the early phases of design, particularly Design for the Environment. In order to include DfX considerations, especially early in the design process, there needs to be access to knowledge and information that is usually only applicable further downstream in...

Process Intensification toward Reduced Exergy Destruction in Methane Upgrading

Creator:: Freiberg, Lucas J.
Abstract:: Exergy relates to thermodynamic value or usefulness in the universe. In this dissertation, three methods in the realm of "process intensification" are explored to reduce exergy destruction by equipment and processes that are used to convert and upgrade methane. Thermodynamic efficiency of a virtual heat exchanger is improved with a...

Fully-integrated mm-Wave Full-duplexing and MIMO Multi-beamforming Receiver Techniques for 5G and Beyond

Creator:: Garg, Robin
Abstract:: In recent years, the research community's interest in fully integrated mm-Wave wireless communication systems has increased significantly. With the standards for 5G NR now in place, the focus has shifted to actual deployment. Mm-Wave systems provide wider bandwidths, higher capacity, and lower latency than existing systems such as 4G. Higher...

Data-Driven Environmentally Sustainable Product Design: A Shift Toward Increased use of Sustainable Design Activities in the Early Design Phase

Creator:: Ferrero, Vincenzo J.
Abstract:: Modern product design drives the boundaries of innovation by encompassing complex Design-for-X objectives, and the inclusion of multidimensional stakeholders. This growing complexity in product design has left design teams unequipped, as classical design theory is bounded by designer experience, expertise, and cognition. One novel approach to tackling product complexity is...

New Graphite Intercalation Chemistry with Alkaline Earth Metals

Creator:: Xu, Wei
Abstract:: Novel graphite intercalation compounds (GICs) and associated chemistry have been explored, specifically: (1) containing alkyl- substituted imidazolium cations; (2) a series containing alkaline earth metal (Mg, Ca, Sr, Ba) cations with ethylenediamine (en) co-intercalates; (3) showing reversible intragallery M-M bonding and (4) via electrochemical intercalation of Mg cations with potential...

The Design of Good Work

Creator:: Hattrup, Steven H.
Abstract:: Work occupies a considerable amount of time in most peoples’ lives and can be a source of great pleasure or a source of pain. To enhance peoples’ experience at work, we must first understand how to measure and improve the design of work. This research sought to do just that,...
