Recent advances on first-principles modeling for the design of materials in CO2 capture technologies
(Elsevier, 2018-11-10)Novel technologies in consideration of industrial sustainability (IS) are in urgent need to satisfy the increasing demands from the society. IS realizes the production of materials and while maintaining environmental and ... -
A non-local plasticity model of stimulated volume evolution during hydraulic fracturing
(Elsevier, 2018-10-02)Hydraulic fracturing in naturally fractured rocks often leads to the creation of a stimulated zone in which the target rock formation is deformed and fractured by the reactivation and shear dilation of natural fractures ... -
Empirical validation of the Gamification User Types Hexad scale in English and Spanish
(Elsevier, 2018-10-13)Gamification, the use of game elements in non-game systems, is now established as a relevant research field in human-computer interaction (HCI). Several empirical studies have shown that gameful interventions can increase ... -
Cooperative Autonomous Vehicle Speed Optimization near Signalized Intersections
(University of Waterloo, 2018-12-12)Road congestion in urban environments, especially near signalized intersections, has been a major cause of significant fuel and time waste. Various solutions have been proposed to solve the problem of increasing idling ... -
Portraits from the State Mental Hospitals
(University of Waterloo, 2018-12-12)The thesis is a short book of fifty sketches. I felt I threw out a significant amount of other material – plans, sketchup models, physical models, and photographs. Many people I had shown my work to were uninterested in ... -
Highly pressurized partially miscible liquid-liquid flow in a micro-T-junction. I. Experimental observations
(American Physical Society (APS), 2017-04-24)This is the first part of a two-part study on a partially miscible liquid-liquid flow (liquid carbon dioxide and deionized water) which is highly pressurized and confined in a microfluidic T-junction. Our main focuses are ... -
Highly pressurized partially miscible liquid-liquid flow in a micro-T-junction. II. Theoretical justifications and modeling
(American Physical Society (APS), 2017-04-24)This is the second part of a two-part study on a partially miscible liquid-liquid flow ( carbon dioxide and deionized water) that is highly pressurized and confined in a microfluidic T-junction. In the first part of this ... -
Photocatalytic performances of ZnO nanoparticle film and vertically aligned nanorods in chamber-based microfluidic reactors: Reaction kinetics and flow effects
