Impacts of seismic line restoration on CO2, CH4, and biomass
(University of Waterloo, 2021-10-21)Oil and gas exploration has resulted in over 300,000 km of linear disturbances, known as seismic lines, throughout boreal peatlands across Canada. Sites are left with altered hydrologic and topographic conditions that ... -
Identifying Fenton-Reacted Trimethoprim Transformation Products Using Differential Mobility Spectrometry
(ACS Publications, 2018-04-17)A transformation product of trimethoprim, a contaminant of emerging concern in the environment, is generated using an electro-assisted Fenton reaction and analyzed using differential mobility spectrometry (DMS) in combination ... -
Ligand Specificity and Affinity in the Sulforhodamine B Binding RNA Aptamer
(Elsevier Inc., 2020-07-18)Binding affinity and selectivity are critical properties of aptamers that must be optimized for any application. The sulforhodamine B binding RNA aptamer (SRB‐2) is a somewhat promiscuous aptamer that can bind ligands ... -
A Scalable Recoverable Skip List for Persistent Memory on NUMA Machines
(University of Waterloo, 2021-10-20)Interest in recoverable, persistent-memory-resident (PMEM-resident) data structures is growing as availability of Intel Optane Data Center Persistent Memory increases. An interesting use case for in-memory, recoverable ... -
An Anisotropic Subgrid-Scale Parameterization for Large-Eddy Simulations of Stratified Turbulence
(AMS, 2020-10-01)Subgrid-scale (SGS) parameterizations in atmosphere and ocean models are often defined independently in the horizontal and vertical directions because the grid spacing is not the same in these directions (anisotropic ... -
Resolution Dependence and Subfilter-Scale Motions in Idealized Squall-Line Simulations
(AMS, 2020-07-08)In this paper, the sensitivity of idealized squall-line simulations to horizontal resolution, subgrid turbulence mixing scheme, and subfilter-scale motion is discussed. Inconsistent results from numerical simulations ... -
Normal Mode Spectra of Idealized Baroclinic Waves
(AMS, 2020-02-01)Normal modes are used to investigate the contributions of geostrophic vortices and inertia–gravity waves to the energy spectrum of an idealized baroclinic wave simulation. The geostrophic and ageostrophic modal spectra ... -
Realizing Surface-Driven Flows in the Primitive Equations
(AMS, 2015-05-01)The surface quasigeostrophic (SQG) model describes flows with surface buoyancy perturbations with no interior quasigeostrophic potential vorticity at small Rossby number Ro and O(1) Burger number, where quasigeostrophic ... -
Dependence of Model Energy Spectra on Vertical Resolution
(AMS, 2016-04-01)Many high-resolution atmospheric models can reproduce the qualitative shape of the atmospheric kinetic energy spectrum, which has a power-law slope of −3 at large horizontal scales that shallows to approximately −5/3 in ... -
Constitutive Behaviour and Formability of Pre-aged AA7075 Sheet in a Warm Forming Process
(University of Waterloo, 2021-10-19)Warm constitutive and formability characterization of a high strength aluminum alloy (AA7075) was performed for a range of pre-aged (i.e. under-aged) tempers, strain rates and temperatures. The pre-aging processes were ... -
Topographically generated internal waves and boundary layer instabilities
(AIP, 2015-01-06)Flow over topography has been shown to generate finite amplitude internal waves upstream, over the topography and downstream. Such waves can interact with the viscous bottom boundary layer to produce vigorous instabilities. ... -
Random forcing of geostrophic motion in rotating stratified turbulence
(AIP, 2017-12-29)Random forcing of geostrophic motion is a common approach in idealized simulations of rotating stratified turbulence. Such forcing represents the injection of energy into large-scale balanced motion, and the resulting ... -
Wall turbulence response to surface cooling and formation of strongly stable stratified boundary layers
(AIP, 2019-08-20)This paper investigates the processes by which stable boundary layers are formed through strong surface cooling imposed on neutrally stratified wall-bounded turbulence using high-resolution direct numerical simulation at ... -
A Systematic Review of Multimedia Tools for Cybersecurity Awareness and Education
(ACM, 2021-01-02)We conduct a comprehensive review covering academic publications and industry products relating to tools for cybersecurity awareness and education aimed at non-expert end-users developed in the past 20 years. Through our ... -
Measuring and modelling soil erosion in agricultural systems: Evaluating the application of UAVs and SfM-MVS for soil erosion research
(University of Waterloo, 2021-10-19)Soil erosion in agricultural systems is a pressing issue for agricultural sustainability. Accelerated rates of soil erosion from conventional agricultural practices continues to outpace the rate of natural soil regeneration, ... -
From Nosy Little Brothers to Stranger-Danger: Children and Parents’ Perception of Mobile Threats
(ACM, 2016-06-21)The rise in mobile media use by children has heightened parents' concerns for their online safety. Through semi-structured interviews of parent-child dyads, we explore the perceived privacy and security threats faced by ... -
