Modern control theory offers mathematically rigorous and powerful solutions to many dynamic systems. Its limitations are that the classes of dynamic systems covered by the theory are limited to linear systems or certain well-structured nonlinear systems, and the adaptation of the controllers are often slow if the controller parameters are far away from their desired values. On the other hand, the ...

Window materials are an essential component of some advanced propulsion concepts which require high pressures, high temperatures, low energy losses, and low weights. Window materials must possess a combination of properties such as high mechanical strength, high melting point, high transparency, low density, and good resistance to the operating environment. CeraNova proposes the development of f ...

In this STTR project, Boston Applied Technologies, Inc. (BATi), teaming up with Prof. Di Bartolo’s group at Boston College, aims at developing a large size (300 mm x 300 mm) updatable 3D display with photorefractive polymers for battlefield and command and control applications. The proposed 3D display system features fast response (feasible to video-rate), high diffraction efficiency, and relati ...

SMI in partnership with Stanford University will perform research to develop and apply new methods to analyse and predict stability and performance of a distrubuted control for a gas turbine engine.

The Air Force desires development of a commercial production source for nonlinear optical (NLO) gallium arsenide semiconductor crystals with orientation patterning, i.e., OP-GaAs. The Phase I project has demonstrated feasibility for a fabrication method of OP-GaAs which exclusively utilizes processes anticipated to be available from commercial vendors and at Physical Sciences Inc (PSI). Molecula ...

ABSTRACT: Close integration of photonic devices with silicon complementary metal-oxide semiconductor (CMOS) electronics can yield significant performance improvements in many applications. The recent development of novel integrated structures in silicon including waveguides, resonators, and photodetectors will enable dramatic reductions in size, weight, and power for components implementing compl ...

The Giner, Inc. Phase I program will examine the response to explosive and toxic gas simulants of sensor arrays using a combination of specifically doped metal oxides (DMO) developed at Giner, Inc. in conjunction with metallophthalocyanine (MPc) thin films developed at the University of California at San Diego (UCSD). Electronic controls developed for the MPc sensors will be evaluated also for th ...

ZONA Team proposes in Phase II to develop a general nonlinear methodology with a new and expedient reduced-order-modeling-based procedure as well as direct numerical simulation capability for nonlinear aeroelastic design/analysis of air-vehicles and MAVs under continuous dynamic morphing The proposed methodology, called NANSI.AE, has significant novelty and merits in that it integrates multidisci ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

ABSTRACT: Physical Sciences Inc. (PSI) and the University of Tennessee Space Institute (UTSI) will develop an innovative system to measure and control the cryodeposit layer thickness that develops on cold (~20 K) surfaces in cryogenic radiometric calibration chambers. Currently removing the cryo-layer involves a lengthy process that warms the entire cryo-system to desorb the cryo-layer that incr ...
