  • A self-calibrated, reconfigurable RF LNA

    Creator:
    Jayaraman, Karthik
    Abstract:
    Modern wireless System-on-Chips (SoCs), such as mobile handsets, sensor networks, and mm-wave systems, integrate an entire RF system on a single CMOS chip. Such highly complex systems require significant on-chip digital signal processing to help improve the performance of highly sensitive analog/RF components. The IC market being competitive, the ability...

  • Determination of the Filippov solutions of the nonlinear oscillator with dry friction

    Creator:
    Moreland, Heather L.
    Abstract:
    In previous papers by Awrejcewicz in 1986 and Narayanan and Jayaraman in 1991, it was claimed that the nonlinear oscillator with dry friction exhibited chaos for several forcing frequencies. The chaos determination was achieved using the characteristic exponent of Lyapunov which requires the right-hand side of the differential equation to...

  • Transition metal solar absorbers

    Creator:
    Altschul, Emmeline Beth
    Abstract:
    A new approach to the discovery of high absorbing semiconductors for solar cells was taken by working under a set of design principles and taking a systemic methodology. Three transition metal chalcogenides at varying states of development were evaluated within this framework. Iron pyrite (FeS₂) is well known to demonstrate...

  • Modeling and application of multispectral oceanic sun glint observations

    Creator:
    Luderer, Gunnar
    Abstract:
    The atmospheric radiative transfer model MOCARAT was developed and is presented in this thesis. MOCARAT employs a Monte Carlo Technique for the accurate modeling of band radiances and reflectances in an atmospheric system with a ruffled ocean surface as a lower boundary. The atmospheric radiative transfer is modeled with consideration...

  • Moisture Resistance of Wood-Based Composite Materials

    Creator:
    Molina, Luis
    Abstract:
    Dimensional stability of wood-based composites with changing moisture content remains an important challenge in the industry for many applications. Wood modification technologies have shown significant improvement in dimensional stability by altering the chemistry of the wood substrate, or by filling the available space in the wood microstructure that otherwise would...

  • Forb Community Response to Various Disturbances in the Pacific Northwest Bunchgrass Prairie

    Creator:
    Watson, Brogan L.
    Abstract:
    Observed declines in native pollinator species worldwide has generated concern and focused research into the disturbances, past and present, which may have contributed to these losses. In grasslands, for example, habitat degradation and fragmentation from historical and current crop production and livestock grazing has left only a few remnants of...

  • Experimental investigation of carbon dioxide (CO₂) laser perforation as a potential skin pretreatment for sugar infusion process of frozen blueberries

    Creator:
    Fujimaru, Tomomi
    Abstract:
    The purpose of this research was to examine the feasibility of carbon dioxide (CO2) laser perforation and its potential utilization as a novel skin pretreatment for the sugar infusion process of IQF (individually quick frozen) blueberries. In the first study, IQF blueberries were treated with varying degrees of laser perforation...

  • Synthesis and oligomerization of y,4-Diamino-2-oxo-1(2H)-pyrimidinepentanoic acid

    Creator:
    Nelson, Jeffrey Stephen
    Abstract:
    Described herein is the synthesis of an uncharged stereoregular oligonucleotide analog consisting of cytosine bases linked at specific intervals to a polyamide backbone derived from (L)-glutamic acid. Preparation of this analog entailed borane reduction of (L)- pyroglutamic acid to give optically pure lactam alcohol 9. Tosylation and alkylation with cytosine...

  • Analysis of Mutations Affecting Cooperation in Pseudomonas aeruginosa Populations

    Creator:
    Robinson, Tanner M.
    Abstract:
    In a process called quorum sensing (QS), the bacterial pathogen Pseudomonas aeruginosa uses small diffusible signals to coordinate cooperative behaviors via secreted “public goods”. Under QS-dependent growth conditions, social cheaters arise with mutations in lasR, the gene for the primary QS signal receptor. These cheaters do not produce public goods....

  • Expression of the Ets family of transcription factors in early bovine and ovine embryo development

    Creator:
    Collins, Jonna Erin
    Abstract:
    Maternally-derived transcripts and proteins support early bovine and ovine embryo development until the 8- to 16-cell stage, at which time embryonic transcripts become essential for continued development. One purported mechanism for the switch from maternal to zygotic control of development (maternal to zygotic genome activation; MZGA) is the appearance of...
