Recently, there has been much interest in performing demand-driven data-flow analysis in software development environments. Demand-driven analysis techniques compute data-flow fact(s) for a particular program point, rather than computing data-flow information for the entire program. The existing work in this area, however, assumes that the static call graph is available for the entire program. ...

In this paper we present a model of distribution as a natural consequence of deterministic concurrency; a purely declarative form of concurrency that preserves referential transparency. This extends the demand driven model used as the operational basis of functional languages, into one with multiple independent demands without the need to allow non-determinism to appear at the user level. The a...

NASA Ames Research Center, in cooperation with the FAA, is studying automation for aiding airport surface traffic management. The Surface Management System (SMS) is a decision support tool that will provide information and advisories to help controllers and air carriers collaboratively manage the movements of aircraft on the surface of busy airports, improving capacity, efficiency, and flexibil...

Television networks compete for both viewers and advertisers. Recent theoretical work has modeled the impact of viewers’ and advertisers’ network usage on the other group. Empirical work has not kept pace. I estimate viewer demand for television programs as a function of program characteristics, audience flow, day and time effects, and time given to advertising. I find audiences are highly resp...
