SBC: UES INC Topic: AF09BT30
Military applications for CBRNE/GWTO and C4ISR require R&D for materials to protect personnel and equipment. However, challenges remain in experimental synthesis and characterization of new materials, such as providing insight into observed properties for further advancement. Thus, it is essential to develop a predictive modeling and simulation approach that will not only provide a fundamental u ...STTR Phase I 2010 Department of DefenseAir Force
SBC: ULTIMARA INC Topic: AF08BT18
We propose to develop ultradense plasmonic integrated devices and circuits for optical interconnect compatible with the electronic circuitry. In our proposal, we will employ engineered metallic nanostructures that combine energy concentration by plasmonic lenses and retardation-based plasmonic resonances to even further boost the efficiency of materials exhibiting optical nonlinearity. These plas ...STTR Phase I 2010 Department of DefenseAir Force
SBC: VOSS SCIENTIFIC LLC Topic: AF09BT08
Military applications for the use of directed electromagnetic energy, which include high power microwave (HPM), seek to disrupt electronic systems by exploiting non-linearity in semiconductors. While current mode second breakdown is a thermal non-linearity often exploited, it has been demonstrated that a broad class of semiconductors have more subtle non-linearities that can be utilized to induce ...STTR Phase I 2010 Department of DefenseAir Force
SBC: NESS ENGINEERING, INC. Topic: AF09BT14
Recent advances in dielectric and magnetic materials have spurred renewed interest in the field of solid state pulse and RF burst generation using Non-Linear Transmission Lines (NLTL) . The NLTL approach to HPM and UWB generation eliminates the need for an electron beam, vacuum system and magnets required in conventional HPM sources. Furthermore, the novel waveforms of NLTL generated pulses promi ...STTR Phase I 2010 Department of DefenseAir Force
SBC: MATHSENSE ANALYTICS Topic: AF09BT21
The key to making quantum key distribution practical (especially for free-space applications) is to be able to use weak laser pulses (WLP) instead of single photons, while at the same time making sure that any third party wanting to avoid detection and mount an eavesdropping attack is restricted to using beam-splitting rather than photon-number splitting (PNS). In this effort, we propose a novel s ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Apolent Corporation Topic: AF09BT06
We apply the theory of partially observable Markov decision processes (POMDPs) to the design of guidance algorithms for controlling the motion of unmanned aerial vehicles (UAVs) with on-board sensors for tracking multiple ground targets. While POMDPs are intractable to optimize exactly, principled approximation methods can be devised based on Bellman’s principle. We introduce a new approximation ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Elissar, LLC Topic: AF09BT06
The growing complexity of future military systems demands the development of high-performance nonlinear control algorithms. The goal of this proposal is to develop a specially designed software/hardware architecture to enable real-time autonomous closed-loop control of nonlinear high-dimensional dynamical systems. Following the recent success of pseudospectral (PS) computational control methods in ...STTR Phase I 2010 Department of DefenseAir Force
Multi-scale Physics-Based Models for alpha-betaTitanium Alloys Accounting for Higher-Order Microstructure Statistics.SBC: MRL MATERIALS RESOURCES LLC Topic: AF09BT29
Modern military and civilian aircraft technologies are pushing the performance envelope through design and use of new advanced materials with superior property combinations. Aircraft powerplant manufacturers are facing intense competition to efficiently deliver ever increasing thrust, while meeting the highest standards of reliability and performance over an expanded service life. These performanc ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Kassoy Innovative Science Solutions Topic: AF09BT38
Quantitative predictions of reactive flow dynamics from large-scale simulations of Liquid Rocket Engines (LRE) appear to be model dependent. Relationships and coupling among the dominant mechanisms most responsible for destabilization are obscured by the complexities of the model and subtle consequences of inherent ad hoc approximations not supported by mathematical rationale. The reliability of ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Physical Engineering Corporation Topic: AF09BT39
This Phase I STTR proposal will demonstrate nanostructured “metal-black” coatings to enhance absorption by thin film solar cells. The problem is that silicon has low absorption due to its indirect gap. The opportunity is that nano-scale metallic scattering centers increase the effective optical path length and enhance the solar electric-field strength in thin-film solar cells, leading to more ...STTR Phase I 2010 Department of DefenseAir Force
