  • Ocean electric energy extraction opportunities

    Creator:
    Zhang, Heng
    Abstract:
    The world's oceans contain tremendous renewable energy potentials. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world [1]. This thesis provides a comprehensive description of the state-of-the-art of ocean energy extraction technologies and lessons learned from...

  • Dissecting mechanics of chromosome segregation and cleavage furrow induction

    Creator:
    Chen, Wei
    Abstract:
    Accurate chromosome segregation and cell cleavage are critical to maintaining genomic integrity. Both events involve the spindle apparatus, but the exact mechanics is as puzzling as the contradicting models proposed in the last two centuries. In this dissertation, current prevailing models of chromosome segregation and cell cleavage are tested using...

  • Ectopic overexpression of Arabidopsis CBF genes enhances freezing tolerance of two potato species

    Creator:
    Pino, María-Teresa
    Abstract:
    Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...

  • Information space mapping with adaptive multiplicatively weighted Voronoi diagrams

    Creator:
    Trubin, Stanislav I.
    Abstract:
    Traditional application of Voronoi diagrams for space partitioning creates Voronoi regions, with areas determined by the generators’ relative locations and weights. Especially in the area of information space (re)construction, however, there is a need for inverse solutions; i.e., finding weights that result in regions with predefined areas. In this thesis,...

  • Some potential mechanisms for finely-tuned regulation of phospholipase C-β isozymes : studies of dimerization and phosphatidylinositol 3,4,5-trisphosphate activation

    Creator:
    Zhang, Yong
    Abstract:
    Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled signaling pathways. Prior research suggested that some isoforms of PLC-β may exist and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation assays of differentially-tagged PLC-β constructs and sizeexclusion chromatography of native PLC-β support homodimerization...

  • 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 dual-path 2-0 MASH ADC with dual digital error correction

    Creator:
    Zhang, Zhenyong
    Abstract:
    This dissertation presents a dual-path 2-0 MASH (Multi-stAge-noise -SHaping) ADC with two verified digital corrections of DAC mismatch error and quantization noise leakage. By using these two techniques, the requirements for the analog circuits are greatly relaxed. The dual-path structure generates two outputs, one only composed of conversion errors, the...

  • Degradation kinetics of taxol using mass spectroscopy

    Creator:
    Zhang, Jun
    Abstract:
    Paclitaxel is a very important anticancer drug commonly called Taxol®. We know from previous work (Hoffman, et al., 1998) that Taxol exists in filbert, Corylus avellana L. material. Quantification of Taxol in filbert plant material is painstaking and hitherto was accomplished by rapidly processing single batches in a complicated procedure...

  • 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...

  • A wideband low-power continuous-time delta-sigma modulator for next generation wireless applications

    Creator:
    Chen, Xuefeng
    Abstract:
    Delta-Sigma (ΔΣ) analog-to-digital converters (ADCs) are widely used in wireless transceivers. Recently, continuous-time (CT) ΔΣ ADCs gain growing interest in wireless applications for their lower power consumption and wider input bandwidth as compared with the discrete-time (DT) counterparts. In this thesis, a wideband low-power CT ΔΣ modulator for next generation...
