We analyze numerically a moving interface in the random-field Ising model which is driven by a magnetic field. Without thermal fluctuations the system displays a depinning phase transition, i.e., the interface is pinned below a certain critical value of the driving field. For finite temperatures the interface moves even for driving fields below the critical value. In this so-called creep regime...

In this work, we present a hybrid partitioned deep learning framework for the reduced-order modeling of moving interfaces and predicting fluid–structure interaction. Using discretized Navier–Stokes in arbitrary Lagrangian–Eulerian reference frame, generate full-order flow snapshots point cloud displacements as target physical data inference coupled dynamics. The operation methodology comes by c...

1. I N T R O D U C T I O N We study high-resolution finite-volume methods for the one-dimensional conservation law qt + f (q ) z = ~ (x ,q ) (1) on a moving grid, where the interface x~ between grid cells varies with time t~. Figure 1 shows a typical moving grid over one time step. We show how the wave-propagation algorithms developed in [1] and implemented in the CLAWPACK software [2] can be m...

We propose a system for controlling in real time the localisation of sound sources. The system, called MidiSpace, is a real time spatializer of Midi music. We raise the issue of which interface is the most adapted for using MidiSpace. Two interfaces are proposed: a 2D interface for controlling the position of sound sources with a global view of the musical setup, and a 3D/VRML interface for mov...

A simple model for an interface moving in a disordered medium is presented. The model exhibits a transition between the two universality classes of interface growth in the presence of quenched disorder. Using this model, it is shown that the application of constraints to the local slopes of the interface produces avalanches of growth that become relevant in the vicinity of the depinning transit...

The level set method for capturing moving fronts was devised by Osher and Sethian in [3]. The goal is to compute and analyze the motion of an interface Γ that is moving according to its own geometries and/or the external physics of the underlying problem. The key idea behind this method is to implicitly represent the interface Γ as the zero level set of a smooth enough function φ, known as leve...

An effective technique for detecting and tracking moving vehicles in a typical parking lot is implemented. The technique involves adaptive realtime background subtraction and shadow removal followed by a set of morphological operations in order to enhance the foreground mask. The mask is then used to draw a distinct bounding box over the moving vehicles in the original video sequence. The outpu...
