Viscosity and low temperature lubricant characteristics determine turbine engine starting capability, and lubricant motion with respect to the contact surfaces at low ambient temperature. Such low ambient temperatures influence the oil viscosity and also the variation of its curve shape versus the temperature. According to the aforementioned research method, the requirements for accuracy and rel ...

Traumatic head and neck injuries account for 16-33% of all war-related injuries and are a leading cause of mortality upon evacuation to a definitive care setting. Therapeutic advances are urgently needed for these soldiers. This application is focused on treating one of the most important determinants of outcome from severe head injury, the degree and duration of elevated intracranial pressure (I ...

Adventium has created a trust-driven engineering solution that will enable assured deployment and control of million-plus scalable lightweight cybercraft to help maintain US freedom of action, and deny freedom of action to our adversaries. Our constraint-based approach reduces uncertainty by identifying robust architectures and configurations that can satisfy mission requirements for large-scale d ...

This Phase II proposal extends the technique developed during Phase I for protecting CPI into a commercially viable and generally applicable source-to-source transformation engine. In addition, we expand the Phase I approach to support high-performance secure computation through careful division of tasks, between a slower secured processor, and multiple high-performance general-purpose COTS proce ...

Streaming 10GHz+ analog-bandwidth data from two high precision, synchronized, sigma-delta analog to digital converters are captured in a cyrogenic environment via a unique low noise amplifier array. A commercial optical data pathway, multi-TeraFLOP processor and conventional networking provide for either time-limited buffering or real-time processing and data dissemination. System extensibilit ...

Tunable clocks targeting 10GHz through greater than 70GHz are optically generated, distributed and interfaced into an array of one or more cyrogenic, electronic operating environments. Design criteria include exceptionally low jitter and skew between clocks presented to each array element (less than 10FS RMS). Use of single-mode, optical fiber technology supports arrays distributed across 600 me ...

The potential for combustion instability has historically been a hindrance in developing rocket engines, and nearly always represents the major technical risk in engine developments. This proposal addresses innovative approaches toward prediction of liquid rocket engine combustion instability, as well as innovations in full-scale engine stability verification. Specific objectives are to demonstrat ...

The overall objective of the proposed research is to develop a comprehensive, efficient, and well-validated computational method for the prediction of thermodynamic and hydrodynamic performance of various types of two-phase cooling systems for next generation electronics. The proposed computational method will use a novel two-level approach that involves a system-level solution with an embedded co ...

This Phase II project will develop a prototype Inter Working Function (IWF) system supporting Voice over Internet Protocol (VoIP) to a narrowband tactical device. This solution shall integrate the more essential features of a prototype radio gateway and the tactical VoIP application, e.g., the dynamic variable data rate processor that provides most efficient use of IP bandwidth. This solution will ...

The Navy desires the use of RHIB’s in littoral waters for MCM because of its many advantages. However, these advantages can only be accomplished by providing a towed minesweeping approach that allows the RHIB to adequately perform the required mission within its limited towing capacity. The Phase I program established a baseline approach for an electrically driven, towed Acoustic Source that was ...
