he application of tactical spacecraft or satellite constellations in support of warfighters has tremendous benefit in a dynamic battlefield environment. Today warfighters must queue behind a long list of higher-priority requests and wait for scarce opportunity to access space-based assets. By the time the information collected becomes available, it is often obsolete and has little tactical valu...

Directorate, we are developing architectures for commanding and controlling a cluster of cooperating satellites through autonomous software development for the TechSat 21 program (see the “TechSat 21” sidebar starting on page XX). Many space missions require large, monolithic satellites. This often results in costly, complex, failure-prone vehicles whose physical size constraints limit their pe...

Robert Burns Woodward's publications exhibit a beauty and majesty infrequently seen in the scientific literature. Excerpts from Woodward's publications are presented along with a discussion of his literary personality and the effect of his writings on his contemporaries and on the style of the chemical literature that followed.

In this paper, the logic of acts of commanding ECL II introduced in Yamada (2007b) will be extended in order to model acts of promising together with acts of commanding. Effects of both kinds of acts are captured in terms, not of changes they bring about on propositional attitudes of their addressees, but of changes they bring about on deontic status of relevant action alternatives; they are mo...

Bolstering up a military unit, e.g., an infantry platoon on a recce mission, by robots often is a double-edged sword. On the one hand, the robots are able to support the soldiers in multiple ways, they can transport bulky equipment, they can enter risky spots, and they may have sensor suits that help to detect dangers of all kinds. On the other hand, robots need to be equipped with energy sourc...
