ABSTRACT: Clear Science Corp. and Princeton University propose to develop and demonstrate software that accurately and efficiently simulates the full set of physics associated with aircraft flight operations. The critical attributes of the proposed framework are accuracy, computational efficiency, and inclusiveness. More accurate computational models will support higher fidelity analysis during ...

ABSTRACT: We propose to develop an assured information sharing framework for cloud-based systems that leverages our ongoing work in the areas of policy-based usage management and semantic interoperability. The development of this framework will involve the creation of a novel approach to information sharing that treats security as a commodity that can be dynamically provisioned within the cloud, ...

ABSTRACT: ORBITEC will develop a new diagnostic to acquire simultaneous planes of velocity and temperature data at very high repetition rates. This diagnostic relies on a novel pulse burst laser system, a phosphor thermometry technique, and the mature PIV method. The work plan will involve developing and testing the laser, refining the integrated technique, and demonstrating it in a supersonic ...

latereThis proposal describes the development of a process to synthesize low defect Ge1-xSnx and SiyGe1-x-ySnx layers on silicon and silicon-on-insulator (SOI) substrates through low thermal budget laser and rapid thermal annealing/crystallization for high performance mid-wave infrared (MWIR) photo detectors and integrated Si-based optoelectronic devices. In phase I, we demonstrated synthesis of G ...

The problem addressed in this effort is to automatically learn historical ephemeris space catalog time, position, and velocity entity track update error uncertainties (i.e., without track error covariances) and to automatically (e.g., without expert event labeling) produce: – unmodeled non-gravitational space catalog update flags – abnormal unmodeled catalog update flags with abnorma ...

System reliability is a fundamental requirement for safety-critical weapons systems. A key challenge is identifying reliability problems early so that they can be fixed quickly and cheaply. Reliability problems are often integration problems: integration often reveals that flaws that seemed minor in isolated components but lead to serious system-wide reliability problems. The combination of static ...

ABSTRACT: Phosphor materials are currently being utilized in a wide variety of applications. The requirements for phosphors have become more and more stringent with smaller and smaller particles being required. In the Phase I program UES Inc. in collaboration with Penn State University has demonstrated the feasibility of a few approaches for high rate production of high efficiency IR to IR up-con ...

The proposed project will develop three actively configurable metamaterial of relevance to both i) MDA’s high-priority and near-term need for stray light testing and diagnosis and ii) the interceptor functions of THAAD, Ascent Phase Interceptors, MKV and Space Systems. Phoebus’s configurable metamaterials aperture arrays will consist of single-layer metallic thin films patterned with light-cha ...

Recent technology advances have enabled the simulation community to achieve greater realism in virtual training environments, including physics-based simulated sensor views. As new methods for sensor view generation are developed, the lack of readily available supporting data to populate these specialized techniques limits their implementation. Currently the capability is not available to efficien ...

ABSTRACT: A smaller transmitter package operating in C-band with greater power efficiency will pave the way for newer, compact weapons to utilize the expanded frequency range at C band. BENEFIT: Reduced payload weight, giving off less heat, with longer battery life.
