In this paper, a framework utilizing constructs from category theory for compositional specification of dependable distributed protocols has been proposed. The paper shows how by defining external interfaces of basic modules, and functional mappings linking two different modules, a larger or more complex protocol can be composed and verified. To illustrate the proposed approach, the composition...

We present new serial and parallel algorithms for multilevel graph partitioning. Our algorithm has coarsening, partitioning and uncoarsening phases like other multilevel partitioning methods. However, we choose fixed nodes which are at least a specified distance away from each other and coarsen them with their neighbor nodes in the coarsening phase using various heuristics. Using this algorithm...

Introduction Conclusions References

The two-phase partitioning bioreactor concept appears to have a great potential in enhancing the productivity of many bioprocesses. The proper selection of an organic solvent is the key to successful application of this approach in industrial practice. The integration of fermentation and a primary product separation step has a positive impact on the productivity of many fermentation processes. ...
