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 Self-Contained Electro-Hydraulic Brake System
(University of Waterloo, 2015-09-21)The automotive brake system plays a significant role not only in the deceleration and stopping process, but also in many stability control strategies. To overcome the limitations of conventional brake systems and to improve ... -
A new series of semiconducting azine polymers and their applications in organic electronics
(University of Waterloo, 2021-01-26)The rise of renewable energy and the urgency of sustainable development make organic solar cells (OSCs) or organic photovoltaics (OPVs) valued. Among so many donor materials for bulk heterojunction structure, P3HT is one ... -
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. ... -
New strategies for analysis of particulate loaded water
(University of Waterloo, 2016-05-16)This thesis describes the application of thin film solid phase microextraction (TF-SPME) for monitoring of time weighted average (TWA) concentrations and for investigating partitioning of UV filters and biocides in aquatic ... -
New Structure Types among Copper Chalcogenides by Mixing Tellurium with Sulfur or Selenium
(University of Waterloo, 2010-09-30)There is evidence for the existence of non-classical bonding in several binary antimonides, selenides, and tellurides. Owing to such non-classical bonding, some of these solid materials exhibit exciting semiconducting and ... -
A New Technique for Characterizing Multi-Temperature Convection with Application in Building Energy Simulation
(University of Waterloo, 2017-06-19)Glazing systems with attachments such as shades and insect screens are known as complex fenestration systems (CFS). The ASHRAE Window Attachment Tool (ASHWAT) for modeling heat transfer through a CFS are based on a general ... -
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 ... -
New urban ecological restoration techniques: Testing the short-term effects of adding deciduous leaf litter and plant residue compost on topsoil quality and native herbaceous plant establishment
(University of Waterloo, 2016-09-27)Urban expansion has led to native habitat destruction. Meanwhile, cities produce large quantities of plant residue wastes. To explore the potential to use plant residues to restore native habitats in cities, this thesis ... -
New Views on the Cosmological Big Bang
(University of Waterloo, 2017-09-20)This dissertation is a collection of four different proposals to describe the early universe. Each will draw from insights of different areas of physics to suggest a description which differs from the standard inflationary ... -
A New Wilderness Lookout: Reimagining the Fire Lookout for Ecological Stewardship and Community Engagement
(University of Waterloo, 2020-09-02)Canada is steward to 10% of the worlds’ forests. They play a global role in producing oxygen and sequestering carbon. Nationally timber is a major industry that is an integral part of Canada’s economic strategies. Climate ... -
“New York is a State of Mind”: Race, Marginalization, and Cultural Expression in Postwar New York City
(University of Waterloo, 2011-09-02)While the urban crisis debate has expanded to examine a variety of American cities, the general exploration of how African Americans have responded to, and challenged, racial and urban inequality remains focused on grassroots ... -
