Abstract: A programmable switch for broadband signals having a modular design in which input cards, bridging cards and output cards are interconnected through a common backplane to form a switching matrix having a Clos architecture. All connections between cards are made through the backplane to decrease the complexity of the switch and are arranged to minimize the length of signal traces to minimize signal loss. The backplane is unique in that it is configured with venting holes to facilitate the flow of cooling air therethrough. All modules, including input cards, output cards and bridge cards are hot swappable.

Abstract: A methodology for semi-automatic unification of models of business processes permits accurate comparison of business processes across government agencies or other organizations despite heterogeneity of language and style in the original models. Input into an algorithm includes a set of models produced by different organizations that describe roughly equivalent business processes (the original models). Output includes a single integrated model in which similarities are made explicit in shared generic layers of the model, while differences are represented in organization-specific layers that inherit from the generic layers (the unified model). Internally, the system represents the original and unified models in description logic using the Web Ontology Language (OWL).
