  • Micro total analysis system for in-situ and autonomous spectrophotometric monitoring of iron in groundwater

    Creator:
    Koch, Corey R.
    Abstract:
    We have developed a compact micro total analysis system (μTAS) to serve as a platform for in-situ spectrophotometric water quality monitoring. Individual fluidic, optical, and electrical components were designed, developed, and characterized. These components were combined in both an integrated (single lithographic “chip-based” platform) and a modular manner. The microfluidic...

  • New methods for finite field arithmetic

    Creator:
    Yanik, Tuğrul
    Abstract:
    We describe novel methods for obtaining fast software implementations of the arithmetic operations in the finite field GF(p) and GF(p[superscript k]). In GF(p) we realize an extensive speedup in modular addition and subtraction routines and some small speedup in the modular multiplication routine with an arbitrary prime modulus p which...

  • Development of volatile compounds in Pinot noir grapes and their contributions to wine aroma

    Creator:
    Fang, Yu
    Abstract:
    It is often perceived that late maturity of grape gives a more complex aroma profile to Pinot noir wine, however, there is little understanding of the basic flavor chemistry of grape maturity on wine aroma. The aroma contributing compounds in Pinot noir were first identified by aroma extract dilution analysis...

  • Public health impact assessment : a science-based methodology for comparing biological agents

    Creator:
    Appt, Julia R.
    Abstract:
    Humans have long suffered the effects of disease causing biological agents. Today bioterrorism appears to be on the rise while at the same time global and ecological changes have resulted in the emergence of new diseases. Potential repercussions of an epidemic pose immense challenges requiring a methodical approach to align...

  • Comparison of MODIS binary and fractional snow cover mapping techniques in the Himalayan Region, Nepal

    Creator:
    Tuladhar, Preeti
    Abstract:
    Satellite remote sensing is an effective tool for mapping snow covered area. However, complex terrain and heterogeneous land cover, due to vegetation and patchy snow cover, present challenges to snow cover mapping. This research compares two techniques for mapping snow covered area: binary and enhanced fractional snow cover mapping techniques....

  • Biological insertion of nanostructured germanium and titanium oxides into diatom biosilica

    Creator:
    Jeffryes, Clayton S.
    Abstract:
    There is significant interest in titanium oxide and germanium-silicon oxide nanocomposites for optoelectronic, photocatalytic, and solar cell applications. The ability of the marine diatom Pinnularia sp. to uptake soluble metal oxides from cell culture medium, and incorporate them into the micro- and nano-structure of their amorphous silica cell walls, called...

  • Development of an improved system for Oregon to accurately quantify dense-graded hot mix asphalt pavement density

    Creator:
    Darra, Suraj
    Abstract:
    The Oregon Department of Transportation (ODOT) standard specifications require a minimum density for the construction of dense-graded hot mix asphalt (HMA) pavements. Currently, the standard specifications call for density measurements for quality control (QC) and quality assurance (QA) testing to be made using nuclear density gauges that are calibrated using...

  • Revisiting output coding for sequential supervised learning

    Creator:
    Hao, Guohua
    Abstract:
    Markov models are commonly used for joint inference of label sequences. Unfortunately, inference scales quadratically in the number of labels, which is problematic for training methods where inference is repeatedly preformed and is the primary computational bottleneck for large label sets. Recent work has used output coding to address this...

  • Inorganic thin-film solar cells

    Creator:
    Spies, Jack Alexander
    Abstract:
    The primary objective of this thesis is to explore new absorber and p-type window layer materials for thin-film solar cell applications. A new thin-film electron beam deposition system has been installed, is now operational, and has been used to deposit several types of solar cell absorber layers. Material investigations include...

  • Modified VLSI designs for error correction codes

    Creator:
    Chen, Lupin
    Abstract:
    Nowadays, error correction codes have become an integral part in almost all the modern digital communication and storage systems. With the continuously increasing demands for higher speed and lower power communication systems, efficient VLSI implementations of those error correction codes have great importance for practical applications. In this thesis, several...
