A density functional theory analysis on syngas adsorption on NiO (100) surface
(Elsevier, 2019-12-31)Oxygen carrier (OC) design can effectively improve the performance of chemical looping combustion (CLC) and realize fossil fuel combustion at low energy-cost CO2 capture. This study describes the adsorption principles of ... -
Dependence modeling for multi-type recurrent events via copulas
(Wiley, 2019-09-20)When several types of recurrent events may arise, interest often lies in marginal modeling and studying the nature of the dependence structure. In this paper, we propose a multivariate mixed-Poisson model with the dependence ... -
The dependence of evaporative efficiency of vegetated surfaces on ground cover weight fractions in mesic ecosystems
(University of Waterloo, 2023-05-15)Bare soil evaporation has been studied extensively, but less is certain regarding how site-specific features, especially the overstory tree canopy and ground covers, mediate evaporation processes. Inspired by recent advances ... -
Dependence of model energy spectra on vertical resolution
(American Meteorological Society, 2016-03)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 ... -
Depletion gels from dense soft colloids: Rheology and thermoreversible melting
(American Institute of Physics, 2014-08-01)Upon addition of small nonadsorbing linear polymers, colloidal glasses composed of large hard spheres melt and eventually revitrify into the so-called attractive glass regime. We show that, when replacing the hard spheres ... -
Depth-sensing thermal stability of accumulative fold-forged nanostructured materials
(Elsevier, 2021-04)Accumulative fold-forging (AFF) as a newly developed severe plastic deformation (SPD) process based on the repetitive fold-forging steps is implemented for the production of the layered UFG (~200 nm) AA8006 alloy and ... -
Deriving effective vaccine allocation strategies for pandemic influenza: Comparison of an agent-based simulation and a compartmental model
(Public Library of Science, 2017-02-21)Individuals are prioritized based on their risk profiles when allocating limited vaccine stocks during an influenza pandemic. Computationally expensive but realistic agent-based simulations and fast but stylized compartmental ... -
Describing the resource utilisation and costs associated with vertebral fractures: the Build Better Bones with Exercise (B3E) Pilot Trial
(Springer, 2020-03-26)Summary This analysis examined costs/resources of 141 women with vertebral fractures, randomised to a home exercise programme or control group. Total, mean costs and the incremental cost-effectiveness ratio (ICER) were ... -
Desiderata for Exploratory Search Interfaces to Web Archives in Support of Scholarly Activities
(Association for Computing Machinery, 2016-06)Web archiving initiatives around the world capture ephemeral web content to preserve our collective digital memory. In this paper, we describe initial experiences in providing an exploratory search interface to web archives ... -
Design and development of pH-responsive polyurethane membranes for intravaginal release of nanomedicines
(Elsevier, 2018-12-01)The objective of this study was to develop and characterize a novel intravaginal membrane platform for pH-triggered release of nanoparticles (NPs), which is essential for efficient intravaginal delivery of certain effective ... -
Design and evaluation of a predictive powertrain control system for a plug-in hybrid electric vehicle to improve the fuel economy and the emissions
(SAGE, 2014-09-30)In this article, a power management scheme for a plug-in power-split hybrid electric vehicle is designed on the basis of the model predictive control concept of charge depletion plus charge sustenance strategy and the ... -
Design and evaluation of a real-time fuel-optimal control system for series hybrid electric vehicles
(Inderscience publishers, 2012)We propose a real-time optimal controller that will reduce fuel consumption in a series hybrid electric vehicle (HEV). This real-time drive cycle-independent controller is designed using a control-oriented model and ... -
Design and evaluation of an observer-based disturbance rejection controller for electric power steering systems
(SAGE, 2015-08-13)The goal of this paper is to develop an observer-based disturbance rejection electric power steering (EPS) controller to provide steering assistance and improve the driver’s steering feel. For the purpose of control design, ... -
Design and Evaluation of Technologies for Informed Food Choices
(ACM, 2022-10-04)Technology increasingly mediates our everyday interactions with food, ranging from its production and handling to the experience of preparing and eating it with friends and family. However, it is unclear whether these ... -
Design and Preliminary Validation of The Player Experience Inventory
