The semantic grid is the result of semantic web and grid researchers building bridges in recognition of the shared vision and research agenda of both fields. This paper builds on prior experiences with both agents and grids to illustrate the benefits of bringing agents into the mix. Because semantic grids represent and reason about knowledge declaratively, additional capabilities typical of age...

Truncation-error analysis is a reliable tool in predicting convergence rates of discretization errors on regular smooth grids. However, it is often misleading in application to finitevolume discretization schemes on irregular (e.g., unstructured) grids. Convergence of truncation errors severely degrades on general irregular grids; a design-order convergence can be achieved only on grids with a ...

The highest priority for operators of critical infrastructure, including electrical power supply grids, is to ensure a reliable, secure, and cost-efficient energy supply. New challenges have fundamentally changed the nature of how power grids are operated today. These challenges include the integration of renewable and decentralized energy sources, the need for continuous network optimization, ...

We study routing and sorting on grids with diagonal connections. We show that for so-called h-h problems faster solutions can be obtained than on comparable grids without diagonals. In most of the cases the number of transport steps for the new algorithms are less than half the on principle smallest number given by the bisection bound for grids without diagonals.

We present a cut cell method in R for enforcing Dirichlet and Neumann boundary conditions with nearly incompressible linear elastic materials in irregular domains. Virtual nodes on cut uniform grid cells are used to provide geometric flexibility in the domain boundary shape without sacrificing accuracy. We use a mixed formulation utilizing a MAC-type staggered grid with piecewise bilinear displ...
