Resource virtualization concepts are in heavy commercial use for optimizing the performance of distributed applications. Resource virtualization allows resources to be allocated and adapted on-the-fly, and enables a wide range of distributed computing, networking, and sensing applications. However, resource virtualization has traditionally been developed for fixed, stable networks, and cannot adeq ...

There are many situations in DOD missions when soldiers could operate much more effectively if they could successfully recall previously presented information that is vital for mission execution. However, the quantity of information supplied to today’s Warfighter is constantly increasing. This is due to greater reliance on network-centric operations and the expanding range of missions Warfighter ...

A narrow-band microbolometric detector is proposed to the address need for a low-cost, portable system to perform chemical and biological threat detection. An approach is shown to achieve a narrow-band bolometric detector whose response can be tailored to both a desired peak wavelength and bandwidth. The approach will enable the design of an array of detectors meeting the requirements for chemical ...

A boat’s coxswain is adept at analyzing the wave environment, adjusting the craft’s propulsion system and control surfaces to mitigate its motions and reduce the chance of capsizing. There is a significant predictive component in the coxswain’s control decisions. Unmanned surface vehicles (USVs) lack the benefit of a highly trained coxswain reading and predicting oncoming waves - existing au ...

This proposal is being submitted in response to the solicitation topic N10A-T002 (Development of a Computational Method for Prediction of After Burning Effect) by BUSA Engineering Consulting (Dr. Jianghui Chao) in collaboration with University of Florida (PI: Prof. S. Balachandar). The overall objective of the proposed effort is to contribute to national defense and security by advancing the state ...

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 ...

Northwest UAV Propulsion Systems proposes using our purpose built heavy fuel engine designed and built in the USA for small unmanned aerial systems in the tier 2 & 3 class. We will be adding a lightweight ceramic material set combined with FEA (Finite Element Analysis) and heavy fuel atomizer (IRAD Project) to create a lightweight engine for a SUAS or STUAS class UAVs. The Ceramic material set is ...

Magnolia Solar proposes to develop an innovative high efficiency single junction solar cell working with Prof. Diana Huffaker and her group and utilizing multi photon absorption in InAsSb/AlAsSb quantum dot solar cells. The proposed structure has unique qualities required by Intermediate band solar cell theory to achieve ultra high conversion efficiency. This system has a potential to achieve effi ...

This proposal addresses the attainment of conversion efficiency exceeding 35% in a single-junction solar cell. Non-absorption of long wavelength photons and thermallization of short wavelength photons accounts for the loss of over half of the incident energy in a single junction cell; however, a large fraction of this energy could be captured if the spectrum is first modified by an efficient phot ...

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 ...
