Higher efficiency solar cells are needed to reduce solar-array mass, volume, and cost. This project proposes: (i) Reliable, validated models for simulation, analysis, and design of Quantum Dot Superlattice (QDS) based nano-materials for high-efficiency, radiation-hardened photovoltaic cells and photodetectors; (ii) Verify and demonstrate models by experiments; (iii) Implement novel models in CFDR ...

This effort will extend the Phase I design, development, implementation, testing and performance evaluation of an automated prototype Multisensor Attributes and Contextual Information-Aided Track Correlation Algorithm. The proposed algorithm integrates the following modules based modified/enhanced existing stand-alone algorithms: a) A basic Multisensor Data Collection and Feature Extraction Module ...

This proposal is for the development of an architecture for asymmetric and anti-terrorist simulations and the application of that architecture in the design and development of multiple user-friendly, PC-based, artificially intelligent asymmetric combat simulation systems. This effort will utilize a number of existing, mature computer wargames and will focus on enhancements to those game systems u ...

This project will investigate the high speed modulation properties of monolithically integrated coupled-cavity VCSEL arrays with the aim of developing manufacturable, very high speed (>20GHz) directly modulated integrated laser arrays which have very low power dissipation (

ZCT is a volatile memory forensics capability. In Phase I, Pikewerks implemented cross view detection to identify both known and unknown kernel rootkits; and other activity attempting to subvert the normal operations of the operating system. In Phase II Pikewerks proposes to 1) expand collection of memory to include full RAM hibernation storage and RDMA/DMA, 2) expand characterization and analysis ...

Freeform optical surfaces offer advantages over axis-symmetric surfaces in the ability to reduce optical sizes, increase performance and reduce aberrations. However, the description, fabrication and metrology of these surfaces can be difficult and costly, prohibiting their ability to achieve their full potential. Fabrication of these surfaces can be difficult, since they are not axis-symmetric and ...

Bulk III-V ternary substrates are required for the Air Force's next generation of high-speed electronic devices. The detrimental factor in producing single crystals of these materials is unsteady thermo-solutal buoyancy convection that leads to significant macro/micro-segregation and macro/micro cracking. To produce ternary bulk crack-free crystals of uniform composition, a technique is required t ...

In this STTR project, an efficient and high-fidelity computational module to predict non-gray radiative transfer will be developed and validated. The proposed hybrid approach to solve the radiative transport equation (RTE) is a combination of the spherical harmonics (PN) method and the Monte-Carlo method. Non-gray gases will be treated using the full spectrum correlated k-distribution (FSCK) metho ...

Research is proposed for the development and implementation of state of the art, reduced order nonlinear aeroelastic models for multidisciplinary/multi-fidelity optimization problems. Highly efficient and accurate aeroelastic simulation tools will be constructed based upon the mathematical formalism of optimal prediction theory and a novel implementation of a filtered harmonic balance solution met ...

The technology, theory and fabrication of artificial materials and metamaterials have seen impressive progress in the last few years, and various applied fields have benefited of the great flexibility of electromagnetic response that metamaterials may provide at microwaves, infrared (IR) and/or optical frequencies. Negative-refractive and zero-permittivity metamaterials have indeed been proposed f ...
