ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force ...

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: Most cross-domain information flows require some human intervention to ensure that the requirements for releasability are met. Such intervention is expensive and slow, and can form a bottleneck in operations. Unfortunately, fully automated sharing of information across security domain boundaries is also fraught with difficulties due to problems with identifying releasable information, a ...

ABSTRACT: Coordinating and sharing information across multi-level security (MLS) networks are of great interest in many military applications. However, it is very challenging to accomplish those goals due to the heterogeneous security classifications of different network domains. The recent proposed cross-domain solutions (CDS) provide initial steps to make such applications possible. However, th ...

ABSTRACT: This project addresses the need for high-efficiency broad-spectrum PV cells. The proposed original PV design is based on quantum dots with built-in charge (Q-BIC), where the dot charging is realized by selective doping of dot medium. The preliminary data demonstrate that the charged dots placed in a single p-n-junction strongly enhance harvesting and conversion of sub-bandgap photons an ...

ABSTRACT: The objective of this proposal is to develop a fast axis collimating lens for quantum cascade lasers (QCL) which emit in the midwave-infrared (MWIR) range. These lenses must withstand the stress of both continuous wave (CW) and pulsed laser emission. These high laser powers may cause ablation of lens material reducing effectiveness of the optic and leading to failure. Thus, a high damage ...

ABSTRACT: The proposed VPHS (Vision Processor for Helmet Systems) is an advanced technology image processing engine that is designed to provide the image processing requirements of helmet mounted imagery systems. The VPHS will input high resolution image data from imaging sensors, process that data to yield enhanced visualization and output the imagery to operator displays. The VPHS will employ im ...

ABSTRACT: Remarkable advances in artificial intelligence (AI) and human-systems integration are providing aircrew with cockpit automation systems of unprecedented sophistication. Onboard intelligent assistants monitor the aircraft, interpret and carry out pilot commands, and advise the pilot (onboard or remote) as to aircraft and system status, mission progress, threats and alerts. Because pilots ...

ABSTRACT: Speech recognition technology is in wide use today and has been successfully integrated in a number of applications. Most of these applications require a microphone located near the talker. However, when a distant microphone is used where the speaker is at some distance from the microphone as in a hands-free communication, or in a meeting room, there is a major problem with the captured ...

ABSTRACT: Active control of the shock system in a scramjet engine isolator opens possibilities for enhanced engine performance and reduced engine weight by eliminating excess isolator design margin. A successful system will allow for maximum performance from a given engine configuration and will deliver range and efficiency that exceeds those possible using passive unstart control. Our approach is ...
