Numerical considerations for the simulation of proppant transport through fractures
(Elsevier, 2019-09)Injection of a proppant slurry (fluid mixed with granular material) into a reservoir to keep fractures open is a common procedure in hydraulic fracturing treatments. This article presents the numerical methodology for ... -
Geophysical response to simulated methane migration in groundwater based on a controlled injection experiment in a sandy unconfined aquifer
(Elsevier, 2019-09)Geophysical methods have the capacity to detect and characterize gas-phase dynamics in groundwater. Suitable methods can be deployed at surface or within boreholes depending on the required depth of investigation, ... -
Methane gas transport in unconfined aquifers: A numerical sensitivity study of a controlled release experiment at CFB Borden
(Elsevier, 2019-08)Subsurface leakage of natural gas from petroleum wells can impact freshwater aquifers. Accurate prediction of gas migration in the subsurface will depend on knowledge of permeability, porosity, and flow system conditions. ... -
Efficient polyyne formation by ns and fs laser-induced breakdown in ethylene and acetylene gas flow
(Elsevier, 2019-11)We studied polyyne formation by gas phase laser-induced breakdown in ethylene and acetylene gas flow using ns and fs lasers. The results show that acetylene is the most efficient target molecule for generating polyynes ... -
The role of higher education institutions in sustainability initiatives at the local level
(Elsevier, 2019-10-01)Universities are central players and important economic actors in many regions, and many of them are, in general, nationally and internationally active in respect of matters related to sustainable development. But there ... -
Development and characterization of a laminar aerosol flow tube
(AIP, 2006-03)We have developed a new laminar aerosol flow tube (AFT) to study transformations such as ice nucleation, deliquescence, and efflorescence in model atmospheric aerosols. The apparatus consists of four sections which can be ... -
Assessing strain fields in unbalanced unidirectional non-crimp fabrics
(Elsevier, 2020-03)Automation of fabric preforming for resin transfer moulded composite parts motivates the need to characterize the response of dry fabric, which is required for the development of simulation models to predict potential ... -
Patterns of Search Result Examination: Query to First Action.
(ACM, 2019-11-03)To determine key factors that affect a user's behavior with search results, we conducted a controlled eye-tracking study of users completing search tasks using both desktop and mobile devices. We focus our investigation ... -
Prediction of ply crack evolution and stiffness degradation in multidirectional symmetric laminates under multiaxial stress states
(Elsevier, 2018-01-15)A comprehensive study was performed to assess the influence of microscopic ply crack interactions on crack surface opening (COD) and sliding displacements (CSD) for arbitrary plies in general symmetric multidirectional ... -
Predicting the axial crush response of CFRP tubes using three damage-based constitutive models
(Elsevier, 2018-08)Availability of newly developed rapid manufacturing processes may in the near future enable the integration of continuous fiber composites into vehicles while maintaining the volume production rates typical for the automotive ... -
Influence of drilling and abrasive water jet induced damage on the performance of carbon fabric/epoxy plates with holes
(Elsevier, 2017-03-01)The influence of conventional drilling (CD) and abrasive water jet (AWJ) cutting on the fatigue performance of carbon fabric/epoxy plates was investigated. Observations of machined hole regions revealed more severe damage ... -
Quasi-static and dynamic characterization of unidirectional non-crimp carbon fiber fabric composites processed by HP-RTM
(Elsevier, 2019-07)Recently developed high-pressure resin transfer molding (HP-RTM) processes have enabled the integration of lightweight fiber-reinforced composites into automobiles (e.g., frame and roof components, floor segments), which ... -
Time-dependent damage analysis for viscoelastic-viscoplastic structural laminates under biaxial loading
(Elsevier, 2018-11-01)Many composite structures are required to sustain severe thermo-mechanical loads over extended periods of time, during which viscoelastic and viscoplastic behavior can cause the progression of micro-damage. In this paper, ... -
Designing Polymeric Sensing Materials: What are we Doing Wrong?
(Wiley, 2016-08-31)Gas analytes, or volatile organic compounds (VOCs), interact with polymeric sensing materials through various sensing mechanisms. The dominant sensing mechanisms are discussed for different types of VOCs, which are ... -
Processability and tensile performance of continuous glass fiber/polyamide laminates for structural load-bearing applications
(Elsevier, 2018-02)The performance of continuous E-glass/polyamide 6 laminates processed using distinct hot press moulding cycles was assessed and compared with similar E-glass/epoxy and E-glass/polypropylene laminates. The effects of peak ... -
Extrudable hydroxyapatite/plant oil-based biopolymer nanocomposites for biomedical applications: Mechanical testing and modeling
(Elsevier, 2019-07-15)Towards developing bone-inspired, high performance composite biomaterials, two nanocomposite inks, consisting of a plant oil-based biopolymer resin (soybean oil epoxidized acrylate (SOEA)) and silanized nano-hydroxyapatite ... -
Modelling the micro-damage process zone during cortical bone fracture
(Elsevier, 2020-02-01)Cortical bone employs intrinsic toughening mechanisms to delay crack growth initiation and propagation hence increasing its fracture toughness. Computational models of the bone fracture process though do not explicitly ... -
Transport of chloride and deuterated water in peat: The role of anion exclusion, diffusion, and anion adsorption in a dual porosity organic media
(Elsevier, 2019-08)The dual-porosity structure of peat and the extremely high organic matter content give rise to a complex medium that typically generates prolonged tailing and early 50% concentration breakthrough in the breakthrough curves ... -
Random locations of periodic stationary processes
(Elsevier, 2019-03)We consider a family of random locations, called intrinsic location functionals, of periodic stationary processes. This family includes but is not limited to the location of the path supremum and first/last hitting times. ... -
