Displacement Convexity and Minimal Fronts at Phase Boundaries [PDF]
Archive for Rational Mechanics and Analysis, 2008 We show that certain free energy functionals that are not convex with respect to the usual convex structure on their domain of definition, are strictly convex in the sense of displacement convexity under a natural change of variables. We use this to show that in certain cases, the only critical points of these functionals are minimizers.

Impact of Pore-Scale Characteristics on Immiscible Fluid Displacement
Geofluids, 2020 Immiscible fluid flows (drainage displacement) where nonwetting fluid invades porous media filled with wetting fluid are frequently observed. Numerous studies have confirmed the existence of three different displacement patterns which depend on the ...

Geometric displacement volume and flow in the phase of a two-phase hydraulic converter
Research in Agricultural Engineering, 2007 The paper researches the possibilities to replace the parallel flow hydraulic mechanisms in agricultural machinery with hydraulic units with fluid alternating flow as they provide more efficient operation due to their output alternating motion.

A complete solution of cartographic displacement based on elastic beams model and Delaunay triangulation [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 In map production and generalization, it is inevitable to arise some spatial conflicts, but the detection and resolution of these spatial conflicts still requires manual operation.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Sinusoidal phase-modulation interferometer capable of measuring 1D displacement and 2D in-plane displacement [PDF]
EPJ Web of ConferencesInterferometers for displacement measurement with picometer resolution are required. The main cause of degradation of interferometer resolution is air fluctuation. To investigate the effect of air fluctuation on displacement resolution, we have developed
