Multi-frame scene-flow estimation using a patch model and smooth motion prior [PDF]
, 2010 This paper addresses the problem of estimating the dense 3D motion of a scene over several frames using a set of calibrated cameras. Most current 3D motion estimation techniques are limited to estimating the motion over a single frame, unless a strong ...

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 21, 16 November 2024.Abstract The Hadley circulation (HC) has been expanding poleward in recent decades. The Coupled Model Intercomparison Project Phase 6 (CMIP6) models predict that the expansion will accelerate in the future, more so in the Southern Hemisphere (SH). However, the extent of the expansion varies widely among the models. We investigate the mechanisms driving

Mesh Parameterization Meets Intrinsic Triangulations
Computer Graphics Forum, Volume 43, Issue 5, August 2024.Abstract A parameterization of a triangle mesh is a realization in the plane so that all triangles have positive signed area. Triangle mesh parameterizations are commonly computed by minimizing a distortion energy, measuring the distortions of the triangles as they are mapped into the parameter domain.

Noble Gas Anions: An Overview of Strategies and Bonding Motifs
Chemistry – An Asian Journal, Volume 19, Issue 14, July 15, 2024.The chemistry of noble gas anions currently includes species fixed into synthesized salts, detected in the gas phase or in high‐pressure devices, and predicted by theoretical calculations. The matter overall appears as a fascinating puzzle, whose composed pieces suggest exciting opportunities of further developments and novel achievements.

ISIS: a new N-body cosmological code with scalar fields based on RAMSES. Code presentation and application to the shapes of clusters [PDF]
, 2014 Several extensions of the standard cosmological model include scalar fields as new degrees of freedom in the underlying gravitational theory. A particular class of these scalar field theories include screening mechanisms intended to hide the scalar field

Robust finite element methods and solvers for the Biot–Brinkman equations in vorticity form
Numerical Methods for Partial Differential Equations, Volume 40, Issue 3, May 2024.Abstract In this article, we propose a new formulation and a suitable finite element method for the steady coupling of viscous flow in deformable porous media using divergence‐conforming filtration fluxes. The proposed method is based on the use of parameter‐weighted spaces, which allows for a more accurate and robust analysis of the continuous and ...

Distance Spectra of Some Double Join Operations of Graphs
International Journal of Mathematics and Mathematical Sciences, Volume 2024, Issue 1, 2024.In literature, several types of join operations of two graphs based on subdivision graph, Q‐graph, R‐graph, and total graph have been introduced, and their spectral properties have been studied. In this paper, we introduce a new double join operation based on (H1, H2)‐merged subdivision graph.

Solving the Einstein constraints in periodic spaces with a multigrid approach
, 2013 Novel applications of Numerical Relativity demand for more flexible algorithms and tools. In this paper, I develop and test a multigrid solver, based on the infrastructure provided by the Einstein Toolkit, for elliptic partial differential equations on ...
