  • 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...

  • 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...

  • Applications of the thermal wave technique in liquid thermal conductivity measurements and flow field diagnostics

    Creator:
    Wang, Zhefu
    Abstract:
    The thermal wave technique has been explored for the use of liquid thermal conductivity measurement and flow property diagnostics in this dissertation. For liquid thermal conductivity measurements, an experimental technique based on the thermal wave approach is developed. A stainless steel strip functions as both a heating element and a...

  • Topological Design Considering Uncertainty and Hyperelasticity

    Creator:
    Pham, Trung
    Abstract:
    Topology optimization (TO) is a mathematical method to find the optimal size, shape and connectivity of a domain under specified conditions, and has had many applications in engineering design. However, challenges remain in realizing TO as an effective design tool for many design situations. Uncertainty is ubiquitous in nature and...

  • Characterization of Heterostructured Nanocrystalline Metals Processed by High-Pressure Torsion

    Creator:
    Han, Jae-Kyung
    Abstract:
    High-pressure torsion (HPT) is an effective severe plastic deformation (SPD) technique to produce bulk nanostructured materials (BNMs). These BNMs often show a combination of exceptional mechanical and physical properties. Processing of single metals and alloys by HPT has been understood that the homogenous microstructures can be achieved throughout the disk...

  • Modeling Methods for Hydraulic Fracturing Wastewater Treatment Applications

    Creator:
    O'Hern, Hannah
    Abstract:
    Modeling of hydraulic fracturing wastewater treatment systems must be very accurate so it can be used for real-time modeling and control of the process. The treatment of hydraulic fracturing wastewater is complex because of the variability of the composition of hydraulic fracturing wastewater. In this work, literature review of hydraulic...

  • Bi-criteria group scheduling with learning in hybrid flow shops

    Creator:
    Bozorgirad, Mir Abbas
    Abstract:
    In this research, a bi-criteria group scheduling problem is investigated in hybrid flow shop (HFS) environments, where the parallel machines in each stage are unrelated, meaning not identical. The objective of the problem is to minimize a linear combination of the total weighted completion times as a means of complying...

  • Robotic Actuation and Control with Programmable, Field-Activated Material Systems

    Creator:
    Bira, Nicholas P.
    Abstract:
    This dissertation presents novel, field-activated smart material systems for the actuation and control of autonomous robots. Smart materials, a type of material whose properties can be changed with an external stimuli, represent a promising direction to expand upon existing robotic control and actuation methods, particularly in the sub-fields of soft...

  • Bi-Criteria Batching and Scheduling in Hybrid Flow Shops

    Creator:
    Shahvari, Omid
    Abstract:
    In this research, a bi-criteria batching and scheduling problem is investigated in hybrid flow shop environments, where unrelated-parallel machines are run simultaneously with different capacities and eligibilities in processing, in some stages. The objective is to simultaneously minimize a linear combination of the total weighted completion time and total weighted...
