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 ... -
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 ... -
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 ... -
Teaching with an Interactive E-book to Improve Children's Online Privacy Knowledge
(ACM, 2016-06-21)We designed the Cyberheroes interactive e-book and conducted a preliminary user study to test its effectiveness in educating children aged 7 to 9 about online privacy risks. Children and parents found the book to be fun ... -
Cyberheroes: An Interactive Ebook for Improving Children’s Online Privacy
(Scienceopen, 2017-07)We designed, illustrated, and developed Cyberheroes, an educational interactive ebook that teaches children about online privacy. The ebook was evaluated with children and parents, and had positive effects on children’s ... -
Secure Comics: An Interactive Comic Series for Improving Cyber Security and Privacy
(Scienceopen, 2017-07)We designed, illustrated, and developed Secure Comics, an online educational interactive comic series about cyber security and privacy. The three-part comic was evaluated with adults and children, and had positive effects ... -
Engaging Children About Online Privacy Through Storytelling in an Interactive Comic
(Scienceopen, 2017-07)Children’s privacy is put at risk through online sharing of location-based information. We study the effectiveness of an educational interactive comic on improving 11- to 13-year-old children’s privacy knowledge and behaviour ... -
Coordinated path following of unicycles : A nested invariant sets approach
(Elsevier, 2015)We formulate a coordinated path following problem for N unicycle mobile robots as an instance of a nested set stabilization problem. Stabilization of the first set corresponds to driving the unicycles to their assigned ... -
Designing Optimal Terpolymers for Enhanced Oil Recovery (Polymer Flooding)
(ACS, 2020-03-20)Terpolymers of 2-acrylamido-2-methylpropane sulfonic acid (AMPS), acrylamide (AAm) and acrylic acid (AAc) have significant potential to be used in polymer flooding for enhanced oil recovery. Our earlier work has explored ... -
Evaluation of Doped and Undoped Poly (o-anisidine) as Sensing Materials for a Sensor Array for Volatile Organic Compounds
(Wiley, 2020-06-02)Poly (o-anisidine) (PoANI) and PoANI doped with nickel oxide and zinc oxide were evaluated as sensing materials for four gas analytes (methanol, ethanol, acetone, and benzene). The sensing materials had high sensitivity ... -
Joint Action Storyboards: A Framework for Visualizing Communication Grounding Costs
(ACM, 2021)Building and maintaining common ground is vital for effective collaboration in CSCW. Moreover, subtle changes in a CSCW user interface can significantly impact grounding and collaborative processes. Yet, researchers and ... -
Low Temperature Insights into the Crystal and Magnetic Structure of a Neutral Radical Ferromagnet
(Royal Society of Chemistry, 2021-09-16)The crystal structure of the radical ferromagnet 1a at 2 K reveals a contraction in the unit cell c constant which, at the molecular level, translates into a decrease in slippage of the radical π-stacks and an increase in ... -
Applying Persuasive Design Techniques to Influence Data-Entry Behaviors in Primary Care: Repeated Measures Evaluation Using Statistical Process Control
(JMIR, 2018-10-11)Background: Persuasive design is an approach that seeks to change the behaviors of users. In primary care, clinician behaviors and attitudes are important precursors to structured data entry, and there is an impact on ... -
Can Message-Tailoring Based on Regulatory Fit Theory Improve the Efficacy of Persuasive Physical Activity Systems?
(MDPI, 2019-11-08)Background: Many behaviour-change technologies have been designed to help people with a sedentary lifestyle to become more physically active. However, challenges exist in designing systems that work effectively. One of the ... -
