  • Flex-shape convolution and an interactive image segmentation system

    Creator:
    Zhou, Zheng
    Abstract:
    Semantic image segmentation is a relatively difficult task in computer vision. With the advent of deep learning, semantic image segmentation is increasingly of interest for researchers because of the excellent predictions from Convolutional Neural Network (CNN). However, CNNs have proven to struggle with obtaining global context of image due to...

  • Al2O3 coated LiCoO2 as cathode for high-capacity and long-cycling Li-ion batteries

    Creator:
    Jian, Zelang, Wang, Wentao, Wang, Maoyu, Wang, Yan, AuYeung, Nicholas J., Liu, Miao, and Feng, Zhenxing
    Abstract:
    Lithium-ion batteries (LIBs) as energy storage devices play an important role in all aspects of our life. The increasing energy demand of the society requires LIBs with higher energy density and better performance. We here develop a new and easy-to-scaleup sol-gel method to coat a surface protection layer on commercial...

  • Gold Nanostars: Spectroscopic and Physical Properties

    Creator:
    Zhou, Lixia
    Abstract:
    Tethering fluorophores on metal nanoparticles for metal enhanced fluorescence (MEF) has attracted a lot of attention from scientists interested in fluorescence based approaches. MEF has many benefits in fluorescence related techniques, because the analytical signal increases and enables potentially lower detection limits or better sensitivity. Many types of nanoparticles have...

  • Epsilon-Near-Zero Transparent Conductive Oxides and the Application in Electro-Absorption Modulators

    Creator:
    Zhou, Bokun
    Abstract:
    Transparent conductive oxides (TCOs), such as indium-tin oxide (ITO), have attracted increasing interests in integrated photonics and nanophotonics, owing to their large plasma dispersion and epsilon-near-zero (ENZ) effect. The refractive index modulation induced by free carriers in TCOs leads to a large electro-optic effect that can enable ultra-compact device footprint...

  • Dynamic control of brushless doubly-fed machines

    Creator:
    Zhou, Dongsheng, 1964-
    Abstract:
    This thesis presents the development of dynamic control strategies for the brushless doubly-fed machine (BDFM). A simple open-loop scalar controller is first investigated and its response is found to be oscillatory. Using the speed feedback signal, an improved closed loop scalar control algorithm is designed. Steady state performance is controlled...

  • Studies on effect of stabilizers, chelators and inherent periodicity on nanoparticle antioxidant activity

    Creator:
    Zhou, Zheng
    Abstract:
    The level of reactive oxygen species (ROS) is tightly regulated in biological systems as overproduction can lead to oxidative stress and result in a number of diseases. Due to its negative effects, antioxidants are studied and used against ROS in medicine, pharmaceuticals and therapeutics. Because of issues with the uptake...

  • An in silico Approach to Determine the Influence of Surface Chemical Properties on the Toxicity of Engineered Zinc Oxide Nanoparticles

    Creator:
    Zhou, Zitao
    Abstract:
    Nanotechnology products have long since made their way to markets around the world increasing the concerns about whether nanomaterials pose a risk to our environment or health. It has been suggested that engineered nanomaterial (ENM) with broad applications and rapid commercialization need better risk assessment and regulation. However, the refinement...

  • High speed digital FIR filter design

    Creator:
    Zhou, Bo
    Abstract:
    The objective of this thesis is to design a high speed digital FIR filter. The inputs of the system come from a Delta-Sigma modulator. This FIR filter takes 1024 inputs, multiplies them with their coefficients and adds the results. The main design task is to take the input data, which...

    Creator:
    Zhou, Junlin
    Abstract:
    The material properties of the candidate fiber-reinforced composite materials and different fabrication methods for fiber composites were discussed. The improvement of the hand lay-up process for polyurethane impregnated Kevlar was investigated. Testing samples for lab and prototype tests were fabricated by hand lay-up process. The study showed that fiber composites...
