Here we show how a lattice Boltzmann based approach accurately model acoustic wave propagation in strongly heterogeneous media. Rather than solving a partial-differential wave equation in a continuous medium, the lattice-Boltzmann based method directly simulates the physical processes of wave propagation: transportation, reflection and transmission. It can accurately handle sharp interfaces at any locations along lattice links, and total reflections from free surfaces or empty bubbles. I used empty and nonempty bu...

Classification of information and data of mining in every relevant mining industry plays an important, sensitive, and undeniable role in progressive decision making procedures. Collecting this data in the form of a software collection package can be useful in providing service and information for the future mining activities and industries. Organizing of mining information on base the type of major minerals, geological setting, origin of the forming , and situation of the active and abandoned mines basically leads...
