The word relationships are used to create a directed graph, called a Semantic Relationship Graph (SRG). This SRG is(More)

Our design, Polymorphic Cognitive Agent Architecture (PCAA), is a hardware-software system that supports the requirements for implementing a dynamic multi-unmanned aerial vehicle (UAV) mission planning application(More)
