  • Exploring Indoor Navigation Based on 9-dof Kalman Filter and SLAM Algorithm

    Creator:
    Qin, Shuxian
    Abstract:
    Traditional localization techniques rely on triangulation or trilateration, where in a set of three or more stationary known locations is used to estimate a “client” position. For inertial navigation, these techniques can estimate client positions merely using the measured data from tri-axial accelerometers and gyroscopes. However, the use of double...

  • Wide-bandwidth, high-resolution delta-sigma analog-to-digital converters

    Creator:
    Zanbaghi, Ramin
    Abstract:
    There is a significant need in recent mobile communication and wireless broadband systems for high-performance analog-to-digital converters (ADCs) that have wide bandwidth (BW>5-MHz) and high data rate (>100-Mbps). A delta-sigma ADC is recognized as a power-efficient ADC architecture when high resolution (>12-b) is required. This is due to several advantages...

  • Low power receivers for wireless sensor networks

    Creator:
    Ni, Ronghua
    Abstract:
    Wireless sensor networks are becoming important in several monitoring and sensing applications. Ultra low power consumption in the sensor nodes is important for extending the battery life of the nodes. In this dissertation, two low power BFSK receiver architectures are proposed and verified with prototype implementations in silicion. A 2.4...

  • Information processing errors in linear feedback control systems

    Creator:
    Chong, Hoi-yeung
    Abstract:
    This report is concerned with the analysis of the effect of finite wordlength, channel capacity and source rate in digital feedback control of linear systems. The cases considered are (1) finite wordlength A/D conversion, no feedback delay, ideal ROM (read only memory) controller; (2) finite A/D wordlength (source rate), state...

  • Development of a 300 Hp regenerative motor and generator test facility

    Creator:
    Lewis, Timothy M. (Timothy Michael)
    Abstract:
    A 300 hp motor and generator testing facility is being completed at Oregon State University. The testing center is the largest independent testing facility west of the Mississippi River. This regional resource center will incorporate state-of-the-art features that set it apart from other testing facilities. An induction machine with a...

  • Growth, fabrication and modeling of pseudomorphic laser diodes

    Creator:
    Ebner, John
    Abstract:
    This thesis reports on the crystal growth, fabrication, modeling and performance of Graded Index-Separate Confinement Heterostructure laser diodes which contain pseudomorphic InGaAs as the active region material. Laser epitaxial layers were grown with different indium mole-fractions, and a constant InGaAs layer thickness of 10 nm, on both sides of the...

  • Novel switched-capacitor circuits for delta-sigma modulators

    Creator:
    Yesilyurt, Ayse Gul
    Abstract:
    Oversampled delta-sigma modulation is one of the widely used A/D conversion techniques for narrow bandwidth signals. In this study several new lowpass and bandpass delta-sigma modulator architectures as well as novel pseudo-N-path integrators that can be used in implementing these architectures are proposed. By using multiplexing techniques the new lowpass...

  • Computing Substation Fragility as a Function of Seismic Component Failure

    Creator:
    Stark, William D.
    Abstract:
    The electrical grid of the Western Interconnection is vulnerable to earthquake damage, especially large-magnitude megathrust events, due to the unique seismic profile of the region. However, the size of the Western Interconnection makes it difficult to model seismic failure in electrical substations to the level of detail necessary to improve...
