What you see below are links to conference papers and presentations that document the evolution of my thinking about DELS.  The story is not linear and much of the later content is different from the earlier content.  That is the nature of exploring a concept.  On the other hand, the story is pretty clear in terms of progress toward concepts, semantics, methods and tools that are useful for the design and operational control of DELS.
