  • Methods for evaluating the impact of renewable resource variability on grid operation and planning

    Creator:
    Halamay, Douglas A.
    Abstract:
    With the recent interest in increasing the penetration of renewable energy sources onto the power grid, there has been an unprecedented rapid deployment of wind generation, especially in the US Pacific Northwest. While wind farm developers have continued to expand their operations, power system operators are left to deal with...

  • Adaptive load balancing metric for WLANs

    Creator:
    Ryou, Jong bum
    Abstract:
    As the number of mobile devices accessing large-scale WLANs such as campus and metropolitan area networks increases, the need for load balancing among the cells becomes crucial. In addition, the network must also support some minimum handoff tolerance defined by an application. A number of load balancing techniques have been...

  • Development of a CZT-Silicon Detection System in Support of the Comprehensive Nuclear-Test-Ban Treaty

    Creator:
    Alhawsawi, Abdulsalam M.
    Abstract:
    The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans all nuclear explosion tests for military or civilian purposes. The International Monitoring System (IMS) was established to verify compliance with the treaty. It consists of several monitoring stations that detect: seismic activities, hydrocoustic activities, infrasound waves, and radionuclide particles and noble gases. Radioxenon detection...

  • Automated verilog-to-layout synthesis of ADCs using custom analog cells

    Creator:
    Waters, Allen
    Abstract:
    A procedure for automating the design and layout of analog-to-digital converters (ADCs) is presented. This procedure makes use of the existing synthesis and place-and-route tools that are common in digital circuit design. A method for adding rudimentary analog cells to the standard library is described, allowing the designer to synthesize...

  • Evaluation of partial discharge in inverter driven medium voltage propulsion coils

    Creator:
    Ramme, André
    Abstract:
    Advancements in power electronics to higher power levels and faster switching times allow new machine and systems designs, but also create higher stresses on electric machinery insulation. High performance, pulse-width modulated (PWM) inverters are now available for medium voltage drive systems, and are being considered by the U.S. Navy as...

  • Design techniques for low-voltage and low-power analog-to-digital converters

    Creator:
    Ahn, Gil Cho
    Abstract:
    With the ever-increasing demand for portable devices used in applications such as wireless communication, mobile computing, consumer electronics, etc., the scaling of the CMOS process to deep submicron dimensions becomes more important to achieve low-cost, low-power and high-performance digital systems. However, this downscaling also requires similar shrinking of the supply...

  • 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...

  • Low-voltage data converters

    Creator:
    Meng, Qingdong
    Abstract:
    With the growing demand for portable/consumer electronics, such as digital audio/video (AV), the downscaling of device dimensions, which enables the integration of an increasing number of transistors in a single chip, is mandatory. This trend also continuously pushes the power supply voltage down to reduce the power consumption and improve...
