Semi-automated Generation of Road Transition Lines Using Mobile Laser Scanning Data
(University of Waterloo, 2017-09-18)Recent advances in autonomous vehicles (AVs) are exponential. Prominent car manufacturers, academic institutions, and corresponding governmental departments around the world are taking active roles in the AV industry. ... -
Semi-Automated Methods for Measuring Practice Conformance for Capital Projects
(University of Waterloo, 2020-08-06)The goal of this thesis is to explore semi-automated methods for measuring practice conformance for capital projects. Thorough measurement of practice conformance for capital projects typically requires manual audits. ... -
Semi-Automated Microscopic Traffic Flow Simulation Development Using Smart City Data
(University of Waterloo, 2021-08-24)Microscopic traffic simulation models have been widely used by transportation planners and engineers for conducting various road network planning and traffic engineering tasks. Due to data limitations, traffic simulation ... -
Semi-automatic Road Extraction from Very High Resolution Remote Sensing Imagery by RoadModeler
(University of Waterloo, 2009-05-22)Accurate and up-to-date road information is essential for both effective urban planning and disaster management. Today, very high resolution (VHR) imagery acquired by airborne and spaceborne imaging sensors is the primary ... -
Semi-continuous measurement of oxygen demand in wastewater using biofilm-capacitance
(Elsevier, 2018-09-01)Bio-capacitive coulombs were tested for determination of the 5-day biochemical oxygen demand (BOD5) using a dual-chamber microbial electrochemical cell (MxC) operated at charging (open circuit) and discharging (close ... -
A Semi-Supervised Approach for Kernel-Based Temporal Clustering
(University of Waterloo, 2015-04-23)Temporal clustering refers to the partitioning of a time series into multiple non-overlapping segments that belong to k temporal clusters, in such a way that segments in the same cluster are more similar to each other than ... -
A Semi-Supervised Approach to the Construction of Semantic Lexicons
(University of Waterloo, 2012-03-21)A growing number of applications require dictionaries of words belonging to semantic classes present in specialized domains. Manually constructed knowledge bases often do not provide sufficient coverage of specialized ... -
Semiconductor Device Characterization and Modelling for Effective Design of 5G Front-Ends
(University of Waterloo, 2018-11-27)The realization of fifth-generation mobile communication will require transceiver front-ends that can handle data-rates of multi-gigabits per second. To provide such data-rates, bandwidth in the hundreds of megahertz will ... -
Semiconductor Nanowire Based Piezoelectric Energy Harvesters: Modeling, Fabrication, and Characterization
(University of Waterloo, 2015-12-22)Semiconductor nanowire (NW) arrays’ unique advantages over bulk forms, including enhanced surface area, high mechanical flexibility, high sensitivity to small forces, better charge collection, and enhanced light absorption ... -
The semiconductor properties of passive films and corrosion behavior of stainless steel reinforcing bars in simulated concrete pore solution
(Elsevier, 2019-06)The vulnerability of concrete reinforcing steels to corrosion when depassivation occurs, typically in the presence of chloride, makes it important to understand the nature of the steels’ passive films. In Part I of the ... -
Semicrossed Products, Dilations, and Jacobson Radicals
(University of Waterloo, 2017-08-18)We compute the C*-envelope of the isometric semicrossed product of a C*-algebra arising from number theory by the multiplicative semigroup of a number ring R, and prove that it is isomorphic to T[R], the left regular ... -
Semidefinite Embedding for the Dimensionality Reduction of DNA Microarray Data
(University of Waterloo, 2006)Harnessing the power of DNA microarray technology requires the existence of analysis methods that accurately interpret microarray data. Current literature abounds with algorithms meant for the investigation of microarray ... -
