    The Portevin-Le Chatelier effect of Cu-2.0Be alloy during hot compression by Zhu, Daibo, Wu, Na, Liu, Yang, Liu, Xiaojin, Jiang, Chaohua, Jiang, Yanbin, Zhao, Hongyun, Cui, Shuhui, Xie, Guilan

    Published 2023
    “…As the strain rate increases, the dislocations outpace the diffusion speed of the solute atoms, limiting their ability to effectively pin the dislocations, resulting in lower dislocation density and serration amplitude. …”

    Compatability and equilibrium approach to slender concrete column design (dual project) by Toh, Yi Hui

    Published 2017
    “…This report evaluates and compares the proposed design method with the Australian code AS3600-2001 for slender concrete column. The failure loads of pin-end columns under short term loading and uniaxial bending are used as a pre-determined factor to analyse the data. …”

    A lightweight and high efficiency battery charger for electric vehicles by Yue, Xi Tong

    Published 2015
    “…This auxiliary circuit reactive current is achieved so that zero-voltage switching is guaranteed. Besides, voltage spikes across the output diode bridge of FB converter are eliminated by using two clamp diodes in the circuit, which leads to lower power loss and lower rating of the diodes and output filter capacitor. …”

    Piezoelectric single crystal based one-dimensional phased array for breast tissue imaging by Du, Wenya

    Published 2024
    “…In this thesis, I propose a conformable ultrasound breast patch (cUSBr-Patch) consisting of a one-dimensional (1D) phased array and a nature-inspired patch design, which offers large-area, deep tissue scanning and multi-angle, repeatable breast imaging while avoiding the drawbacks of conventional ultrasound imaging technologies. I used a Yb/Bi-doped PIN-PMN-PT single crystal as the active element due to its superior piezoelectric properties (d33 = 2,800 pC/N, εr = 7,000, k33 = 0.93). …”
