  • Zonal Resource Adequacy for Voltage Control

    Creator:
    Boller, Michael D.
    Abstract:
    In a power system, operators maintain voltage stability through adequate reactive reserves. Maintaining and accessing an efficient allocation of reactive reserves is prohibitively complex because of reactive line losses, the variety of reactive resources, and either limited or variable reactive outputs from renewable sources. By clustering the system into smaller...

  • Zinc tin oxide thin-film transistor current mirror circuits

    Creator:
    Feller, Layannah Elizabeth
    Abstract:
    The central focus of this thesis is the design, fabrication and characterization of amorphous oxide semiconductor (AOS) thin-film transistor (TFT) current mirrors. The thin-film deposition and circuit fabrication methods used to realize zinc tin oxide (ZTO) TFT current mirrors are addressed in order to elucidate the processing challenges for this...

  • Zinc tin oxide thin-film transistor circuits

    Creator:
    Heineck, Daniel Philip
    Abstract:
    The primary objective of this thesis is to develop a process for fabricating integrated circuits based on thin-film transistors (TFTs) using zinc tin oxide (ZTO) as the channel layer. ZTO, in contrast to indium- or gallium-based amorphous oxide semiconductors (AOS), is perceived to be a more commercially viable AOS choice...

  • Wirelessly Powered cm-Scale Sensor for Small Insect Localization Application

    Creator:
    Kang, Jian
    Abstract:
    The prevalence of Internet-of-Things (IoT) applications leads to an increasing focus on the design and optimization of sensor nodes. Battery lifetime and associated costs of battery replacement often limits the long term operation and viability of sensor nodes. RF wireless energy harvesting on the other hand can be appealing since...

  • Window Axial Vision Transformer for Image Classification

    Creator:
    Lee, Jisoo
    Abstract:
    Currently, a popular approach to image classification uses the deep Transformer architecture. In a Transformer, the attention mechanism enables the model to learn efficiently with fewer computational resources than the convolutional neural networks (CNNs). In this thesis, we study the sparse attention mechanism widely used in the Transformers developed specifically...

  • Wind ramp prediction

    Creator:
    Alexander, Chianna M.
    Abstract:
    The number of wind turbines and wind farms in the Pacific Northwest has increased dramatically in the past six years, which represents a significant amount of electrical generation capacity connected to the public electric grid. However, the variable nature of wind sometimes introduces excessive power, or conversely shortages, in power...

  • Wideband discrete-time delta-sigma analog-to-digital converters with shifted loop delays

    Creator:
    Meng, Xin
    Abstract:
    Low-distortion architecture is widely used in wideband discrete-time switched-capacitor delta-sigma ADC design. However, it suffers from the power-hungry active adder and critical timing for quantization and dynamic element matching (DEM). To solve this problem, this dissertation presents a delta-sigma modulator architecture with shifted loop delays. In this project, shifted loop...

  • Wideband and high accuracy delta sigma modulation data converter

    Creator:
    Jung, Youngho
    Abstract:
    Nowadays, needs for wideband and high accuracy analog-to-digital converter are increasing rapidly in manifold applications such as wireless communication, digital video and other consumer electronics. Besides, low power consumption is required to have longer battery life in portable systems. CMOS technology scaling and innovative modulator topology make the implementation much...

  • 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...

  • WebWEPP version 2.0 : Web-based water erosion prediction project

    Creator:
    Gyu Han, Hong
    Abstract:
    The WEPP (Water Erosion Prediction Project) application computes soil loss and sediment yield from a field based on the data on crops, management practices, and operations. In order to make WEPP, which is a Windows-based application, easily accessible, Web WEPP (Web-based WEPP) was developed by our research group. Web WEPP...
