  • Dielectric Properties of Perovskite Ceramics Based on BaTiO3 and Bi(Mg1/2Ti1/2)O3

    Creator:
    Sundahl, Christopher S.
    Abstract:
    The properties of (1-x)BaTiO3-xBi(Mg1/2Ti1/2)O3 (BT-BMT) ceramics were fabricated from reagent-grade ceramic powders by solid-state methods and investigated for solubility, relative permittivity, dielectric loss, polarization, and electromechanical strain. The solubility limit was found to be between x = 0.3 and 0.4. Ba-deficient samples were fabricated, corresponding to stable single-phase compositions; these...

  • 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...

  • From Functional Modeling to Optimization : Risk and Safety in the Design Process for Large-Scale Systems

    Creator:
    McIntire, Matthew G.
    Abstract:
    In order to more effectively design large, complex systems, risk must be accounted for throughout the design process. A systematic way to account for risk is by using system model simulation. During the conceptual design phase, functional models can be drawn to help the engineer design their system's functional architecture....

  • Aircraft wing optimization using B-spline models and panel methods

    Creator:
    Jackson, Danielle Monique
    Abstract:
    This research investigates shape optimization process, using b-spline models and panel methods, to achieve a high lift to drag ratio for an aerodynamic structure. This research is a proof of concept for further research in aerodynamic shape optimization. The coupled process, involving the design and optimization of a random shape,...

  • Accelerating Power-to-Gas Energy Storage Through PEM Electrolyzer Development and Technoeconomic Forecasting

    Creator:
    Taie, Zachary
    Abstract:
    There is strong interest in the energy community to develop technologies that can diffuse low-cost, renewably generated electricity into difficult and slow to decarbonize sectors. One of the emerging areas of interest is renewable natural gas (RNG). RNG has low or no associated net greenhouse gas emissions and can be...

  • Resilient Design for Complex Engineered Systems in the Early Design Phase

    Creator:
    Keshavarzi, Elham
    Abstract:
    There are many uncertainties that complex engineered systems will face throughout their lifecycles due to changes in internal and external conditions. It is desirable for complex engineered systems to be resilient against various uncertainties. The ability to overcome such uncertainties should be embedded into the system from the beginning. However,...

  • Bi-level flexible-robust optimization for energy allocation problems

    Creator:
    Biswas, Arpan
    Abstract:
    A common problem in energy allocation problems is managing the trade-off between selling surplus energy to maximize short term revenue, versus holding surplus energy to hedge against future shortfalls. For energy allocation problems, this surplus represents resource flexibility and is quantified as the surplus energy after meeting the demand. The...

  • Applying Multi-Objective Evaluation to Automated Assembly Planning in Early CAD Design Stage

    Creator:
    Huang, Weifeng
    Abstract:
    Successfully predicting an accurate estimated cost is important in the assembly planning process. When designing an assembly plan, an accurate estimation ensures that the proposed plan can be achieved within the predetermined budget. However, achieving an accurate prediction is a challenge since it requires professional judgment, which is dependent upon...

  • 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,...
