  • A comparative study of lowpass continuous-time delta-sigma modulators with pulse-shaped DACs

    Creator:
    Fang, Jie
    Abstract:
    Recently, continuous-time ΔΣ modulators are appearing increasingly often in both the literature and the marketplace due to their features of inherent antialiasing and relaxed requirements for opamp and so on. However, several nonideal factors such as clock jitter, excess loop delay, inter-symbol interference and so on, degrade the SNR performance...

  • Formation and modification of enduracididine, a nonproteinogenic amino acid

    Creator:
    Tan, Ying
    Abstract:
    Molecular genetic and enzymological techniques have been employed to study antibiotic biosynthesis. In this thesis, we studied the formation and modification of the nonproteinogenic amino acid enduracididine (End), which exists in two important antibiotics, mannopeptimycins (MPPs) and enduracidin. Sequence analysis of the MPP gene cluster revealed that the product of...

  • Fingerprinting and genetic stability of Rubus using molecular markers

    Creator:
    Castillo, Nina Rosa F.
    Abstract:
    Two studies used DNA markers to assess their usefulness in germplasm identification and evaluation of genetic stability in four cryopreserved Rubus accessions that were stored for over 10 years in liquid nitrogen. In the first study, 12 robust Simple Sequence Repeat (SSR) markers were developed from two microsatellite-enriched libraries of...

  • Architecture design of multiplexed incremental analog-to-digital converters

    Creator:
    Zhang, Zhiqing
    Abstract:
    Analog-to-Digital Data Converters (ADCs) used in instrumentation and measurements often require high absolute accuracy, including excellent linearity and negligible dc offset. Incremental data converters (IDCs) provide a solution for such measurement applications. Since IDCs are essentially delta-sigma converters with reset operation before each conversion, they retain most of the advantages...

  • A survey on continuous-time modulators : theory, designs and implementations

    Creator:
    Gao, Xiaoran
    Abstract:
    Recently, delta-sigma modulation has become a widely applied technique for high-performance analog-to-digital conversion of narrow-band signals. Most of the early designs used discrete-time structure for good accuracy and good linearity. The transfer functions are independent of the clock frequency. However, high unity-gain bandwidths of the opamps are required to satisfy...

  • In search of the dress : an analysis of the consumer decision making process of brides

    Creator:
    Weiss, Jennifer D.
    Abstract:
    The US bridal industry has grown over the last 80 years to become a multibillion dollar industry. Surprisingly, little research has been conducted concerning the consumer behavior of brides. The bride is in a situation where purchase decisions need to be made. She has many things she will purchase over...

  • Catalytic chemical vapor deposition synthesis of carbon nanotubes from methane on SiO supported Fe and Fe−Ni catalysts

    Creator:
    Nakagawa, Ayako
    Abstract:
    Influences of operating conditions on the production of carbon nanotubes (CNTs) were studied using Fe and Fe-Ni bimetallic catalysts supported on silicon monoxide (SiO). The catalysts were prepared in three steps: (1) impregnation of SiO powders with ferric nitride or combinations of ferric and nickel nitrides, (2) oxidation of nitrides...

  • Effect of dietary fatty acids, time of feeding and immune response in poultry

    Creator:
    Gonzalez, Dulmelis
    Abstract:
    In the presence of internal or external stressors, the body requires sources of energy that aide cells to combat inflammation. Fatty acids are an important source of energy and are vital components of cell membranes. Dietary fatty acids (n-6 and n-3) are of importance in immune function because they are...

    Creator:
    Du, Ke
    Abstract:
    State-owned forestland in P.R. China has long been an important source of natural resources for communities. The Chinese government has undertaken several conservation initiatives with the intent to restore degraded landscapes and conserve biodiversity, while simultaneously improving the quality of life for rural people. Using Yaze Village, Pingwu County, Sichuan...

  • Alterations in Douglas-fir crown structure, morphology, and dynamics imposed by the Swiss needle cast disease in the Oregon Coast Range

    Creator:
    Weiskittel, Aaron R.
    Abstract:
    Plants respond to defoliation in many different and complex ways, depending on their growth habit and form as well as the extent and duration of the defoliation. Tree crowns have been shown to be quite sensitive to disturbances such as defoliation, however quantitative relationships have rarely been developed, making the...
