The acceleration and deceleration of photons m a plasma provides the means lbr a series of new radiation sources. Previous work on a DC to AC Radiation Converter (DARC source) has shown variable acceleration of photons having zero frequency (i.e., an electrostatic field) to belx~een 6 and 100 GHz (I-3). These sources all had poor guiding characteristics resulting in poor power coupling froln th...

What justifies -in the head of another agent different from the one actingthe obligation to compensate is the fact that the principal agent has lengthen its own action through the implementation of a foreign activity for its own interests. We present two basic modal operators for representing, respectively, intentions in the interest of another agent and agency in the interest of another agent....
