  • A Techno-Economic Assessment Methodology for Advanced Additive and Joining Processes

    Creator:
    Malshe, Harsha A.
    Abstract:
    Integrated manufacturing systems, a combination of subtractive, additive, and joining processes, provide a competitive advantage for manufacturing organizations. As product designs become more complex and capital more scarce, an ideal combination of advanced manufacturing technologies (e.g., powder bed fusion or friction welding), in tandem with traditional subtractive manufacturing systems, can...

  • Accelerating the convergence of the k-eigenvalue problem using a coarse mesh finite differencing scheme in cylindrical geometry

    Creator:
    Hummel, Andrew J.
    Abstract:
    Reactor modeling is largely limited by the computational time required to perform accurate full core calculations. There are many different methods and techniques employed in different reactor simulation codes, but properly modeling all of the physics that takes place in the system requires extensive computational effort. The Coarse Mesh Finite...

  • Amplification of solitary waves along a vertical wall

    Creator:
    Li, Wenwen
    Abstract:
    Reflection of an obliquely incident solitary wave at a vertical wall is studied experimentally in the laboratory wave tank. Precision measurements of water-surface variations are achieved with the aid of laser-induced fluorescent (LIF) technique and detailed temporal and spatial features of the Mach reflection are captured. During the development stage...

  • Breaking Waves Offshore: Measurements and Modeling of Energy Dissipation

    Creator:
    Ticona Rollano, Fadia M.
    Abstract:
    In the presence of strong winds, ocean surface waves dissipate significant amounts of energy by breaking. Here, breaking rates and wave-following turbulent dissipation rate measurements are compared with numerical WAVEWATCH III estimates of bulk energy dissipation. At high winds, the measurements suggest that turbulent dissipation becomes saturated, however the modeled...

  • Computational Study of Smoldering Combustion in Cellulose and Hemicellulose Mixtures

    Creator:
    Mulky, Tejas Chandrashekhar
    Abstract:
    Due to global warming wildland fires are increasing in frequency and severity. In the case of wildland fires, the major modes of combustion occur include smoldering combustion and flaming combustion. Smoldering combustion occurs most commonly in porous fuels like peat, forest duff, and woody fuels, which are available in abundance...

  • Effect of an Idealized Mangrove Forest of Moderate Cross-shore Width on Loads Measured on a Sheltered Structure and Comparison with Predicted Forces

    Creator:
    Mitchell, William T.
    Abstract:
    As coastal communities face increasing chronic and acute hazards, nature-based coastal engineering solutions have experienced a rapid growth in popularity and interest. Recent works on this topic have shown that “Green Infrastructure” may be effective at mitigating coastal hazards and therefore provide sustainable adaptation alternatives to traditional engineering solutions such...

  • Energy-efficient clock generation for communication and computing systems using injection locking

    Creator:
    Ma, Chao
    Abstract:
    The design of high-performance, high-speed clock generation and distribution becomes challenging in terms of phase noise, jitter and power consumption, due to the fast development of communication and computing systems. Injection locking is a promising clocking technique since it can significantly improve the energy efficiency, suppress the phase noise of...

  • Hydrodynamic loads on fiber-optic micro cables

    Creator:
    Evans, Matthew R.
    Abstract:
    A Finite Element Model of a deployed Fiber-Optic Micro Cable (FOMC) was performed using the marine cable modeling software, OrcaFlex. The focus of this study was a parametric analysis of a two-part, towed cable array with the FOMC dragged behind a depressor and connected to a drogue chute. Length-to-diameter ratios...

  • Information Theoretical Analysis of Self-Similar Trees

    Creator:
    Chunikhina, Evgenia V.
    Abstract:
    Tree-like patterns are ubiquitous in nature. Botanical trees, river networks, and blood systems are the most well-known examples of complex hierarchical systems met in observations. Interestingly, many of such systems exhibit statistical self-similarity. There are two main types of self-similarity: Horton self-similarity and Tokunaga self-similarity. Although there is an increased...

  • Model Predictive Control for Underwater Robots in Ocean Waves

    Creator:
    Fernández, Daniel C.
    Abstract:
    Underwater robots beneath ocean waves can benefit from feedforward control to reduce position error. This thesis proposes a method using Model Predictive Control (MPC) to predict and counteract future disturbances from an ocean wave field. The MPC state estimator employs a Linear Wave Theory (LWT) solver to approximate the component...
