Most of the SDL and MSC based test generation methods and tools produce non-concurrent TTCN test cases only. If the test equipment itself is a distributed system, the implementation of such test cases is a diicult task and requires a substantial amount of additional work. In this paper, we explain how concurrent TTCN test cases can be generated directly from SDL system speciications and MSC tes...

With success of deception control theory, founded recently, in an urban warfare application, we propose a strong case for studying deception in ad-hoc micro-sensor network applications for the use cases with a sentient adversary. We use a Lockheed Martin advanced IR&D work, SONUS (SelfOrganizing Networks of Unattended Sensors), as an exemplar that provides robust and scalable solution when rand...

This paper describes the implementation of a GPS/Inertial integrated navigation system, the GI-Eye, that is designed to automatically georeference imagery collected from a digital camera without requiring any ground control for registration. This is accomplished through the use of Wide-Area DGPS (WADGPS) GPS updates, combined with NAVSYS’ tightly coupled GPS/inertial alignment software to provi...

Digital aerial photography acquired with unmanned aerial vehicles (UAVs) has great value for resource management due to flexibility and relatively low cost for image acquisition. The very high resolution imagery (5 cm) allows for mapping bare soil and vegetation types, structure and patterns in great detail. While image acquisition is relatively straightforward, the creation of orthorectified, ...
