  • Applied color processing

    Creator:
    Zhang, Heng
    Abstract:
    The quality of a digital image pipeline relies greatly on its color reproduction which should at a minimum handle the color constancy, and the final judgment of the excellence of the pipeline is made through subjective observations by humans. This dissertation addresses a few topics surrounding the color processing of...

  • Experimental Investigation of Near-Critical Carbon Dioxide in Microchannels for High Flux Cooling Applications

    Creator:
    Travers, Kristen
    Abstract:
    With the continued decrease in size and subsequent increase in power of computer processors, thermal management in electronics is becoming more important than ever before. The chip heat densities are reaching new peaks (> 100 W cm-2) that current cooling methods are not able to keep up with. However, some...

  • Thermodynamis and kinetics of Zr₅₈̣₅Cu₁₅̣₆Ni₁₂̣₈Al₁₀̣₃Nb₂̣₈ bulk metallic glass forming alloy

    Creator:
    Shah, Minalben B.
    Abstract:
    Among recently found multi-component Zr-based bulk metallic glasses (BMG), Zr₅₈.₅Cu₁₅.₆Ni₁₂.₈Al₁₀.₃Nb₂.₈ is characterized by its lower critical cooling rate requirement and absence of beryllium as one of the constituent element which makes its handling more convenient. Its large supercooled liquid regions made possible the study of thermodynamics and kinetics of this...

  • On the fragility and equilibrium phases of metallic glass forming alloys

    Creator:
    Shadowspeaker, Ludi A.
    Abstract:
    The heating rate dependence of the glass transition temperature of the Ni₆₅Nb₃₅, Ni₆₀Nb₃₅Sn₅, Ni₅₉.₃₅Nb₃₄.₄₅Sn62, Ni₆₀(Nb₄₀Ta₆₀)₃₄Sn₆, and Ni₅₇Fe₃Nb₃₅Sn₅ metallic glass forming alloys was investigated with a differential scanning calorimeter (DSC). The inverse heating rate for each DSC experiment was plotted versus inverse temperature and a Vogel-Fulcher- Tamman (VFT) type relation was...

  • Thermal conductivity measurements of amorphous metal thin films via the 3ω method

    Creator:
    Zhan, Kai
    Abstract:
    Amorphous multicomponent metals have promising applications in novel electronic devices because of their atomically smooth surface morphology and lack of grain boundaries. It is important to understand the thermal transport properties of amorphous metals and an accurate measurement of their thermal conductivity will be essential for further improvement of device...

  • A Social Constructivist Perspective Connecting Engineering Practice and Engineering Education

    Creator:
    Panther, Grace C.
    Abstract:
    Calls for reform within engineering education frequently cite the need to better prepare the future workforce for the imminent challenges that they will face. The focus in preparing students for the workforce is often on the educational system and not on understanding the actual workplace. But if we are to...

  • Submerged jet impingement boiling thermal management

    Creator:
    Cardenas, Ruander
    Abstract:
    Technologies such as avionics and power electronics are driving the demand for thermal management schemes towards high heat fluxes and low surface temperatures. Typically, these applications require the dissipation of heat fluxes in the rage of 100-1000 W/cm² while maintaining surface temperatures lower than about 85 °C. Phase-change heat transfer...

  • 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...

  • Radial Velocity Profiles and Magnetic Field Probes for Hypervelocity Plasma Deflagration Jets

    Creator:
    Rodriguez, Jesse A.
    Abstract:
    The fundamental physics of turbulence in plasma is not well understood. Recent studies of the plasma deflagration accelerator in the High Temperature Gasdynamics Lab at Stanford University have demonstrated the presence of small scale instabilities that limit the lifetime of the jet/Z pinch and are not reproduced by coaxial plasma...

  • The iterative thermal emission Monte Carlo method for thermal radiative transfer

    Creator:
    Long, Alex R.
    Abstract:
    For over 30 years, the Implicit Monte Carlo (IMC) method has been used to solve challenging problems in thermal radiative transfer. These problems are typically optically thick and di ffusive, as a consequence of the high degree of "pseudo-scattering" introduced to model the absorption and reemission of photons from a...
