Prime Divisors of the Number of Rational Points on Elliptic Curves with Complex Multiplication
(Wiley, 2005)Let E/Q be an elliptic curve. For a prime p of good reduction, let E(Fp) be the set of rational points defined over the finite field Fp. Denote by ω(#E(Fp)) the number of distinct prime divisors of #E(Fp). For an elliptic ... -
A priori discretization error metrics for distributed hydrologic modeling applications
(Elsevier, 2016-12-01)Watershed spatial discretization is an important step in developing a distributed hydrologic model. A key difficulty in the spatial discretization process is maintaining a balance between the aggregation-induced information ... -
Privatizing Security, Securitizing Policing: The Case of the G20 in Toronto, Canada
(Wiley, 2014-06)Allegations of police brutality, unlawful detention, and other breaches of civil liberties during the G20 in Toronto in June 2010 provide an important case through which to understand the changing nature of security and ... -
Probabilistic Fretting Fatigue Analysis of Bridge Stay Cables at Saddle Supports
(Taylor and Francis, 2020-01)Saddle systems have been used on recent projects to support the cables in cable-stayed and extradosed bridge structures. A major design consideration for these anchorage systems is the in-service fretting fatigue behaviour ... -
Probability distribution of the seismic damage cost over the life cycle of structures
(Elsevier, 2018-05-01)In the life-cycle analysis, the total cost of damage caused by earthquakes is a significant but highly uncertain component. In the current literature, the seismic risk analysis is largely limited to the evaluation of the ... -
Probing Side Chain Dynamics of Branched Macromolecules by Pyrene Excimer Fluorescence
(American Chemical Society, 2016-01-12)Four different pyrene-labeled polymers were prepared by radical copolymerization of n-butyl methacrylate (BMA) and 1-pyrenemethyl methacrylate (PyEG(0)-MA), 1-pyrenemethoxyethyl methacrylate (PyEG(1)-MA), 1-pyrene-methox ... -
Probing the Interactions between Mimics of Pour Point Depressants (PPDs) and Viscosity Index Improvers (VIIs) in Engine Oil Using Fluorescently Labeled PPDs
(American Chemical Society, 2019-03-18)The level of interpolymeric interactions experienced by a pyrene-labeled poly(octadecyl methacrylate) labeled with 6.7 mol% of 1-pyrenebutanol (Py(6.7)-PC18MA) was characterized by fluorescence in the presence of an amorphous ... -
Probing the Role of Internalized Geometric Strain on Heterogeneous Electrocatalysis
(American Chemical Society, 2019-09-09)The chemistry underlying the activation of nickel hydroxide toward electrocatalytic oxygen evolution by incorporation of iron remains a subject of debate. We extract insights into the role of geometric strain on the ... -
The Problem of History in the Age of Abundance
(The Chronicle of Higher Education, 2016-12-11)Our collective cultural heritage faces a serious problem: In the digital age, we can document and "remember" more than ever before. But the scale of historical material is so huge that it will decisively change how scholars ... -
A procedure for determining parameters of a simplified ligament model
(Elsevier, 2017-11-03)A previous mathematical model of ligament force-generation treated their behavior as a population of collagen fibres arranged in parallel. When damage was ignored in this model, an expression for ligament force in terms ... -
Procedure-specific Risks of Thrombosis and Bleeding in Urological Non-cancer Surgery: Systematic Review and Meta-analysis
(Elsevier, 2018-02-01)Context Pharmacological thromboprophylaxis involves a trade-off between a reduction in venous thromboembolism (VTE) and increased bleeding. No guidance specific for procedure and patient factors exists in urology. Objective ... -
Process parameters for hot stamping of AA7075 and D-7xxx to achieve high performance aged products
(Elsevier, 2018-07)This work examines the necessary process parameters for die quenching (DQ) during hot stamping and subsequent age hardening and paint bake cycle (PBC) response for two alloys: AA7075 and a developmental 7xxx alloy (referred ... -
Process Planning for Additive Manufacturing of Geometries with Variable Overhang Angles using a Robotic Laser Directed Energy Deposition system
(Elsevier, 2022-01)In the present work, a novel Laser Directed Energy Deposition (LDED) process planning methodology is proposed to build a dome structure with variable overhang angles. Overhang structures with different overhang angles were ... -
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 ... -
