Wetting, adhesion and droplet impact on face masks
(ACS, 2021-02-12)In the present pandemic time, face masks are found to be the most effective strategy against the spread of the virus within the community. As aerosol-based spreading of the virus is considered as the primary mode of ... -
Monolith: a monolithic pressure-viscosity-contact solver for strong two-way rigid-rigid rigid-fluid coupling
(Association for Computing Machinery, 2020-11)We propose Monolith, a monolithic pressure-viscosity-contact solver for more accurately, robustly, and efficiently simulating non-trivial two-way interactions of rigid bodies with inviscid, viscous, or non-Newtonian liquids. ... -
Constraint bubbles and affine regions: reduced fluid models for efficient immersed bubbles and flexible spatial coarsening
(Association for Computing Machinery, 2020-07)We propose to enhance the capability of standard free-surface flow simulators with efficient support for immersed bubbles through two new models: constraint-based bubbles and affine fluid regions. Unlike its predecessors, ... -
A practical octree liquid simulator with adaptive surface resolution
(Association for Computing Machinery, 2020-07)We propose a new adaptive liquid simulation framework that achieves highly detailed behavior with reduced implementation complexity. Prior work has shown that spatially adaptive grids are efficient for simulating large-scale ... -
Fast and Scalable Solvers for the Fluid Pressure Equations with Separating Solid Boundary Conditions
(Wiley, 2020-05)In this paper, we propose and evaluate fast, scalable approaches for solving the linear complementarity problems (LCP) arising from the fluid pressure equations with separating solid boundary conditions. Specifically, we ... -
Discrete viscous sheets
(Association for Computing Machinery, 2012-07)We present the first reduced-dimensional technique to simulate the dynamics of thin sheets of viscous incompressible liquid in three dimensions. Beginning from a discrete Lagrangian model for elastic thin shells, we apply ... -
A simple finite volume method for adaptive viscous liquids
(Association for Computing Machinery, 2011-08)We present the first spatially adaptive Eulerian fluid animation method to support challenging viscous liquid effects such as folding, coiling, and variable viscosity. We propose a tetrahedral node-based embedded finite ... -
Matching fluid simulation elements to surface geometry and topology
(Association for Computing Machinery, 2010-07)We introduce an Eulerian liquid simulation framework based on the Voronoi diagram of a potentially unorganized collection of pressure samples. Constructing the simulation mesh in this way allows us to place samples anywhere ... -
Tetrahedral Embedded Boundary Methods for Accurate and Flexible Adaptive Fluids
(Wiley, 2010-05)When simulating fluids, tetrahedral methods provide flexibility and ease of adaptivity that Cartesian grids find difficult to match. However, this approach has so far been limited by two conflicting requirements. First, ... -
Accurate viscous free surfaces for buckling, coiling, and rotating liquids
(Association for Computing Machinery, 2008-07)We present a fully implicit Eulerian technique for simulating free surface viscous liquids which eliminates artifacts in previous approaches, efficiently supports variable viscosity, and allows the simulation of more ... -
A fast variational framework for accurate solid-fluid coupling
(Association for Computing Machinery, 2007-07)Physical simulation has emerged as a compelling animation technique, yet current approaches to coupling simulations of fluids and solids with irregular boundary geometry are inefficient or cannot handle some relevant ... -
Hierarchical RLE level set: A compact and versatile deformable surface representation
(Association for Computing Machinery, 2006-01)This article introduces the Hierarchical Run-Length Encoded (H-RLE) Level Set data structure. This novel data structure combines the best features of the DT-Grid (of Nielsen and Museth [2004]) and the RLE Sparse Level Set ... -
“That’s Our Traditional Way as Indigenous Peoples”: Towards a Conceptual Framework for Understanding Community Support of Sustainable Energies in NunatuKavut, Labrador
(MDPI, 2020-07-28)There is a substantial body of literature in North America regarding the social acceptance of renewable energies, particularly wind energy. However, limited research focuses on the experiences of Indigenous Peoples. ... -
ORGANISATIONAL CHANGE IN THE INNOVATING FIRM: SIZE, R&D AND SECTOR EFFECTS
(World Scientific, 2019-08-05)This study investigates whether organisational innovation has positive impacts on small and medium enterprises, using three waves of the South Korean innovation survey. While correcting for endogeneity, we find that the ... -
Optimal inventory decisions when offering layaway
(Taylor & Francis, 2019)This paper presents an inventory management policy for a retailer offering a layaway programme. Layaway is a service provided by retailers that allows budget constrained consumers who have sufficiently high valuations to ... -
Optimal inventory decisions for a risk-averse retailer when offering layaway
(Elsevier, 2020-07-01)Layaway allows economically disadvantaged budget-constrained consumers to purchase expensive items through amortized payments and nominal program fees, as opposed to using high-interest financing options such as credit ... -
Open Shortest Path First Routing Under Random Early Detection
(Wiley, 2018-03-01)In this article, we consider a variant of Open Shortest Path First (OSPF) routing that accounts for Random Early Detection (RED), an Active Queue Management method for backbone networks. In the version of OSPF we consider ... -
Imagery Rescripting of Painful Memories in Social Anxiety Disorder: A Qualitative Analysis of Needs Fulfillment and Memory Updating
(Springer, 2020-09-19)Background Imagery rescripting (IR) is an effective intervention for social anxiety disorder (SAD) that targets autobiographical memories of painful past events. IR is thought to promote needs fulfillment and memory ... -
