In this paper, we present a new approach for the parallel generation and partitioning of unstructured 3D Delaunay meshes. The new approach couples the mesh generation and partitioning problems into a single optimization problem. Traditionally, these two problems are solved separately, first...

The paper aims to explore the concepts of interaction and interactivity presented in different theoretical models in the fields of human‐computer interaction (HCI) and information‐seeking/searching behaviour, and to relate these to information retrieval (IR) research. It is suggested that...

Investigates the online market and its new vocabulary. Defines what is offered and what the ‘e’ and ‘i’ models are. Suggests there are four basic types of online marketplaces, and these are: exchanges; catalogue hubs; MRO hubs; and yield managers. Looks at other models of online sources...

This paper investigates parallel solution methods to simulate large-scale macroeconometric models with forward-looking variables. The method chosen is the Newton-Krylov algorithm, and we concentrate on a parallel solution to the sparse linear system arising in the Newton algorithm. We...

Increasing absorption bistability is studied under realistic conditions with a many-body approach for nonlinear optical absorption in semiconductor quantum wells, combining Coulomb and band structure engineering effects. The theory predicts carrier induced all-optical increasing absorption...
