In probability theory and statistics, diffusion processes are a class of continuous-time Markov process with almost surely continuous sample paths. Diffusion process is stochastic in nature and hence is used to model many real-life stochastic systems.
24 lis 2020 · Understanding diffusion will give you greater insight into how geologic processes function, such as cooling of a magma dike, the cooling of the lithosphere, diffusion of atoms in/out of grains (e.g., the primary process of rock metamorphism) and erosion of fault scarps.
25 paź 2022 · Diffusion of heat through a crystal lattice occurs through two processes. First, heat can be carried by electrons in the form of kinetic energy in metallic rocks. If a region of the rock is heated at one end, the thermal energy excites the electrons, giving them extra energy to move through the rock from regions of high heat to regions of low heat.
ABSTRACT. For Stein’s operator that can be identified as the infinitesimal generator of one-dimensional diffusion, we express the solution of the corresponding Stein’s equation in terms of speed measure and scale function.
8 lut 2013 · Factors controlling ion diffusion relating to ‘time of wetness’ within stones are discussed, (continued saturation, connectivity of pores, mineralogy, behaviour of salts, sedimentary structure), and potential changes in system dynamics as a result of climate change are addressed.
10 maj 2023 · Key Points. Inversion of Cahn-Hilliard dynamic coefficients from photographic images of Zebra rock reveals multiphysics coupled processes. Transition from stripes to spots is triggered by low reaction product (here Fe-Oxyhydroxite) mobility.
8 gru 2023 · The diffusion pattern of the slurry in the fractured rock mass is characterized by vortex-like diffusion. The stability of the fractured rock mass is influenced by both grouting time and pressure, which should be carefully considered during on-site operations.
