This paper discusses an implementation of an adaptive resolution system for modeling regional air pollution based on the chemical transport model STEM. The grid adaptivity is implemented using the generic tool Paramesh. The computational algorithm uses a decomposition of the domain, with the solution in different sub-domains computed at different spatial resolutions. We analyze the parallel com...

Domain decomposition methods are commonly employed within the context of parallel numerical algorithms. Most often, the domain decomposition is performed before the main computation begins. Within the context of mesh generation, parallel mesh generation is desired when the goal is to mesh a very large geometric domain or if very high accuracy is required. In this paper, we propose a novel techn...

The time evolution of the morphology of homogeneous phases during spinodal decomposition is described using a family of morphological measures known as Minkowski functionals. They provide the characteristic length scale L of patterns in a convenient, statistically robust, and computationally inexpensive way. They also allow one to study the scaling behavior of the content, shape, and connectivi...

Project scheduling problems are in practice often restricted by a limited availability of spatial resources. In this paper we develop a decomposition method for the Time-Constrained Project Scheduling Problem (TCPSP) with Spatial Resources. Spatial resources are resources that are not required by single activities, but by activity groups. As soon as an activity of such a group starts, the spati...

I present an extension to the angle-domain decomposition of images migrated using wavefield extrapolation. Traditionally, reflectivity is described by a 1-D function of scattering angle. I show that we can further decompose the image function of other angles related to the structure and acquisition. In the 2-D case, the reflectivity is described function of two angles, while in the 3-D case the...
