Topology-Guided Sampling of Nonhomogeneous Random Fields
Topological measurements are increasingly being accepted as an important tool for quantifying complex structures. In many applications these structures can be expressed as nodal domains of real-valued functions and are obtained only through experimental observation or numerical simulations. In both cases, the data on which the topological measurements are based are derived via some form of fini...
متن کاملOrthogonal decompositions of 2-D nonhomogeneous discrete random fields
Imposing a total-order on a 2-D discrete random eld induces an orthogonal decomposition of the random eld into two components: A purely-indeterministic eld and a deterministic one. The purely-indeterministic component is shown to have a 2-D whiteinnovations driven moving-average representation. The 2-D deterministic random eld can be perfectly predicted from the eld's \past" with respect to the...

متن کاملHeat and mass transport in nonhomogeneous random velocity fields.
The effective equation describing the transport of passive tracers in nonsolenoidal velocity fields is determined, assuming that the velocity field U(r,t) is a function of both position r and time t, albeit remaining locally random. Assuming a strong separation of scales and applying the method of homogenization, we find a Fickian constitutive relation for the coarse-grained particle flux, as t...
