Finding Even Subgraphs Even Faster [PDF]

open access: yes, 2014
Problems of the following kind have been the focus of much recent research in the realm of parameterized complexity: Given an input graph (digraph) on $n$ vertices and a positive integer parameter $k$, find if there exist $k$ edges (arcs) whose deletion ...

Steinitz Theorems for Orthogonal Polyhedra [PDF]

open access: yes, 2009
We define a simple orthogonal polyhedron to be a three-dimensional polyhedron with the topology of a sphere in which three mutually-perpendicular edges meet at each vertex.

FEA Modeling of Soft Tissue Interaction for Active Needles With a Rotational Tip Joint

open access: yesIEEE Access, 2022
A finite element analysis (FEA) model was developed for investigating the design and the tissue interaction of actively steerable needles with a rotational tip joint in soft tissue, based on the coupled Eulerian-Lagrangian (CEL) mesh.

Dense Discrete Phase Model Coupled with Kinetic Theory of Granular Flow to Improve Predictions of Bubbling Fluidized Bed Hydrodynamics

open access: yesKONA Powder and Particle Journal, 2018
Formation, expansion, and breakage of bubbles in single bubble and freely bubbling fluidized beds were studied using an improved hybrid Lagrangian-Eulerian computational fluid dynamics (CFD) approach. Dense Discrete Phase Model (DDPM) is a novel approach

Geometrically nonlinear behavior of lattice domes coupled with local Eulerian instability

open access: yesCurved and Layered Structures, 2020
Structural analysis is an intricate subject when nonlinearities occur. They make the structural behavior complex and may have important consequences in the design choice as well.

Warm and moist air intrusions into the winter Arctic: a Lagrangian view on the near-surface energy budgets [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
In this study, warm and moist air intrusions (WaMAIs) over the Arctic Ocean sectors of Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea, Chukchi Sea, and Beaufort Sea in 40 recent winters (from 1979 to 2018) are identified from the ERA5 reanalysis ...

Evaluation of aerosol–cloud interactions in E3SM using a Lagrangian framework [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
A Lagrangian framework is used to evaluate aerosol–cloud interactions in the U.S. Department of Energy's Energy Exascale Earth System Model (E3SM) version 1 (E3SMv1) for measurements taken at Graciosa Island in the Azores where a U.S.
