Typographical data entry errors and incomplete documents, produce imperfect records in real world databases. These errors generate distinct records which belong to the same entity. The aim of Approximate Record Matching is to find multiple records which belong to an entity. In this paper, an algorithm for Approximate Record Matching is proposed that can be adapted automatically with input error...

Abstract We investigate reactive flow and transport in evolving porous media. Solute species that are transported within the fluid phase taking part mineral precipitation dissolution reactions for two competing phases. The evolution of three phases is not known a-priori but depends on concentration dissolved solute species. To model coupled behavior, phase-field level-set models formulated. The...

n this article, the microscale ice crystal growth behavior under lectrostatic field is investigated via a phase field method, which lso incorporates the effects of anisotropy and thermal noise. The ultiple ice nuclei’s competitive growth as disclosed in existing xperiments is thus successfully predicted. The present approach uggests a highly efficient theoretical tool for probing into the reeze...

We develop in this paper a moving mesh spectral method for the phase-field model of twophase flows with non-periodic boundary conditions. The method is based on a variational moving mesh PDE for the phase function, coupled with efficient semi-implicit treatments for advancing the mesh function, the phase function and the velocity and pressure in a decoupled manner. Ample numerical results are p...

For interface-tracking simulation of two-phase flows, we propose a new computational method, NS-PFM, combining Navier-Stokes (NS) equations with phase-field model (PFM). Based on the free energy theory, PFM describes an interface as a volumetric zone across which physical properties vary continuously. Surface tension is defined as an excessive free energy per unit area induced by density gradie...

We formulate new multi-phase convective heat transfer equations by combining the three-dimensional (3D) Navier–Stokes equations, the energy equation and the Cahn–Hilliard equation for the phase field variable /ðx; tÞ. The density, viscosity, heat capacity and conductivity are functions of /ðx; tÞ. The equations are solved in time with a splitting scheme that decouples the flow and temperature v...

A phase-only hologram applies a modal transformation to an optical transverse spatial mode via phase encoding and intensity masking. Accurate control of the optical field crucially depends on the method employed to encode the hologram. In this Letter, we present a method to encode the amplitude and the phase of an optical field into a phase-only hologram, which allows the exact control of spati...
