A New Segmentation Algorithm for Prostate Boundary Detection in 2D Ultrasound Images
(University of Waterloo, 2003)Prostate segmentation is a required step in determining the volume of a prostate, which is very important in the diagnosis and the treatment of prostate cancer. In the past, radiologists manually segment the two-dimensional ... -
A New Silicon-Based Dielectric Waveguide Technology for Millimeter-Wave/Terahertz Devices and Integrated Systems
(University of Waterloo, 2015-01-19)In recent decades, the millimeter-Wave (mmWave)/THz band has attracted great attention in the research community. The Terahertz frequency band runs from approximately 300 GHz to 3 THz, an incredible 2700 GHz of bandwidth. ... -
A New Transmit Diversity Method Using Quantized Random Phases
(University of Waterloo, 2013-01-23)Wireless communication systems, aside from path-loss, also suffer from small scale up-and- down variations in the power of the received signal. These fluctuations in the received signal power, commonly referred to as ... -
Next-Generation Solid-State Quantum Emitters
(University of Waterloo, 2019-01-31)This thesis details two types of deterministic solid-state quantum emitters, an optically-driven quantum dot source in a tapered nanowire waveguide, and an electrically-driven source implemented by integrating a single-electron ... -
Node Cluster Stability in Vehicular Ad hoc Networks
