"Through theoretical analysis and experimental testing ASI is ascertaining the suitability of using gas plasma for a high-powered, reconfigurable antenna operating in both the S and X-bands of the electromagnetic spectrum. This design would be used todetect and track ballistic missile. We believe this design will allow development of multifunctional, multi-spectral plasma array antennas capable ...

DESCRIPTION (provided by applicant): We will continue development of our Cybertory Virtual Molecular Biology Laboratory software, and create accompanying instructional materials. New modules will work together to support a wide range of virtual experiments. We will develop exercises in the context of existing undergraduate molecular biology and genetics cou ...

DESCRIPTION (provided by applicant): Recreation is a primary factor in the quality of life of people with disabilities. Paddle sports are one of the fastest growing recreational activities. Current canoe seating products cradle the paddler in a flexible fabric or plastic bucket but do not provide the stable base of support required for efficient, independent and equal participation by users with m ...

DESCRIPTION (provided by applicant): An innovative fluorescence system for sensing biomolecular interactions was developed in Phase I that is based on total internal reflection fluorescence (TIRF). The main advantages of this system are integrated microfluidics and a design that allows rapid replacement of TIRF sensor chip. The feasibility of building a highly sensitive and versatile TIRF biosenso ...

"Mass Injection Pre-Compressor Cooling (MIPCC) is a promising technology which can permit convention jet engines, normally limited in speed and altitude, to propel aircraft to substantially higher altitudes and velocities. By injecting coolant ahead of thecompressor and using its heat of vaporization to cool inlet gasses, the engine can operate at substantially higher velocities without exceeding ...

"This SBIR Phase II Proposal seeks to develop the physics-basedfault tolerant technology for sensor networks shown to befeasible in the SBIR Phase I study in response to topic N01-080, "Fault Location in an Intelligent Open Sensor Network." Theproposed approach considers that for Conditional-BasedMaintenance purposes an entire ship can be classified as ahierarchy of subsystems, which conceptually ...

"The primary goal of the proposed Phase II SBIR effort is todevelop and fabricate fault-tolerant optoelectronic logic arraysutilizing GaAs-based monolithic photonic modules in order torealize a high-performance optical network. The optoelectroniclogic arrays include VCSELs and resonant cavity photodetectorswith on-chip multiplexing/demultiplexing. These high-speedinterconnects are realized using ...

Chemical kinetics based solid propellant combustion predictive capabilities have developed to the point where it is possible to compute combustion properties of solid propellants. Specifically, burning rates over a range of pressures and temperatures.This capability will reduce the time, effort, and cost in developing solid propellants for a variety of combustion devices from rockets to air bags. ...

"New requirements for modern gun systems have greatly increasedthe propellant flame temperature and reactivity of the combustionproducts. As a result, thermochemical erosion can greatlyreduced the service life of the gun tubes in these systems.Coatings and liners have been used to mitigate erosion, withmixed results. In order to design a new gun tube which resistsexcessive wear, a thorough under ...

"Solid rocket motors are subject to combustion stability problemswhen the interior combustion processes interact with thecombustion chamber's acoustic modes, resulting in large pressureamplitude fluctuations. While the initial excitation process canbe predicted using linear analysis, the instability often entersa "limit-cycle", in which the maximum pressure amplitude levelsoff. This limit-cycle ...
