High-resolution infrared emission spectroscopy of diatomic and triatomic metal hydrides
(University of Waterloo, 2006)Several hydrides of Group 2 and 12 elements were generated in the gas phase using an emission source that combines an electrical discharge with a high temperature furnace, and their high-resolution infrared emission spectra ... -
High-resolution laboratory spectroscopy of transient metal-containing molecules
(University of Waterloo, 2007-05-14)Ten gaseous transient metal-containing molecules have been synthesized and studied by high resolution spectroscopy. Transient molecules are molecules with a short lifetime, and they play an important role in chemistry ... -
High-Resolution Numerical Simulations of Wind-Driven Gyres
(University of Waterloo, 2011-08-26)The dynamics of the world's oceans occur at a vast range of length scales. Although there are theories that aid in understanding the dynamics at planetary scales and microscales, the motions in between are still not yet ... -
High-resolution spatial and temporal sensitivity of river hydrodynamics: Implications for walleye (Sander vitreus) and lake sturgeon (Acipenser fulvescens) spawning habitat use in a large regulated river
(University of Waterloo, 2014-08-25)A reach-scale, high-resolution investigation of the spatial and temporal characteristics and sensitivities of hydrodynamic metrics on a large, low-relief, hydroelectrically regulated river in northwestern Ontario was ... -
High-Risk Medication Use, Frailty and Hospitalization among Older Assisted Living Residents
(University of Waterloo, 2015-09-11)Background: With substantial comorbidity, high levels of medication use and age-related physiological changes, older adults are at an increased risk of drug-related errors and adverse events. Of particular concern are (i) ... -
High-Speed Analog-to-Digital Converters for Broadband Applications
(University of Waterloo, 2008-01-15)Flash Analog-to-Digital Converters (ADCs), targeting optical communication standards, have been reported in SiGe BiCMOS technology. CMOS implementation of such designs faces two challenges. The first is to achieve a ... -
High-Speed Clocking Deskewing Architecture
(University of Waterloo, 2007-05-10)As the CMOS technology continues to scale into the deep sub-micron regime, the demand for higher frequencies and higher levels of integration poses a significant challenge for the clock generation and distribution design ... -
High-Speed Elliptic Curve and Pairing-Based Cryptography
(University of Waterloo, 2011-04-25)Elliptic Curve Cryptography (ECC), independently proposed by Miller [Mil86] and Koblitz [Kob87] in mid 80’s, is finding momentum to consolidate its status as the public-key system of choice in a wide range of applications ... -
High-Speed Probe Card Analysis Using Real-time Machine Vision and Image Restoration Technique
(University of Waterloo, 2013-08-30)There has been an increase in demand for the wafer-level test techniques that evaluates the functionality and performance of the wafer chips before packaging them, since the trend of integrated circuits are getting more ... -
