innovative technique that obtains training signal from a maximum likelihood estimator. The proposed technique was applied
for modeling stereo-vision sensors and an Infra-Red (IR) proximity sensor used in the robotic work cell available in the
Robotics and Manufacturing Automation (RAMA) Laboratory at Duke University. In addition, the report presents an
innovative method to fuse the probabilistic information obtained from these sensors based on Bayesian formalism in an
occupancy grid framework to obtain three-dimensional occupancy model and key features of the robotic workspace. The
capability of the proposed technique in accurately obtaining three-dimensional occupancy profile and efficiently removing
individual sensor uncertainties was validated and compared with other methods via experiments carried out in the RAMA lab
during this project.

From a governmental science policy viewpoint, the role of astronomers is to turn money into scientific results. The
agencies that find astrophysical research are looking for a return on their investment. As in all scientific fields, the tradition
and the research process require making these results public for sharing and verification. In the case of astronomy, direct
applications are not sought. Its research process contributes to enrich the pool of human knowledge. Still, astronomers want
their productivity measured and the value of the new knowledge base they build assessed and recognized.

The Air Transportation System (ATS) provides competitive advantage to U.S. based commercial enterprises by providing
safe, reliable, fast, and low-cost transportation of goods and the people. The ATS is also an enabler for the tourism industry
and a major source of employment and commerce. Sustaining this competitive advantage requires maintaining a system with
capacity in excess of the demand for travel in the presence of changes in airline business models and other market forces. This
paper describes the FAA s NAS Strategy Simulator and how it can be used to understand and analyze the market-forces
shaping the ATS of the future. Specifically, the NAS Strategy Simulator provides the means for developing contingencies to
adapt to plausible future changes in the airline and transportation industries that will affect the delivery of air traffic services.
In this way the FAA, and their industry partners, can plan the development and testing of new policies and procedures, and
the introduction of new technologies, in a coordinated and economically efficient manner.
