Solving the acoustic wave equation in an oil exploration industrial context aims at speeding up seismic modeling and reverse time migration (RTM). We considered a finite difference approach on a regular mesh, in both two-dimensional and three-dimensional cases. The acoustic wave equation is solved...
Legacy Systems Migration:In IT, reverse engineering can be used to migrate data and functionality from legacy systems to modern platforms. Product Design:Designers may reverse engineer a product to understand its mechanics, materials, or production techniques and use this knowledge to create a new pr...
