More than 1,500 Americans have lost a limb due to traumatic injury in combat in recent years.Upper limb loss can be treated with myoelectric prostheses, but such devices require intensive training to effectively operate. The need to concentrate and continuously react during training often takes amputees many months, with the result that many patients abandon use of the prosthesis. In the Phase I e ...

Military Environmental Control Units (ECUs) are one of the greatest consumers of electric energy in forward operating bases (FOBs). Microchannel condensers have replaced tube-fin coils in both military ECUs and commercial air conditioners to improve system efficiency. Flow into the condenser is single-phase superheated vapor and therefore uniform flow distribution through multiple parallel microch ...

The Archarithms Sensor Resource Manager is a grid based solution that defines objective functions for ranking the utility of both track and search tasks, and provides algorithms for optimizing resource usage based on the developed functions. The method uses a modified assignment algorithm to optimize task assignments over a finite time horizon. An approximated utility function allows optimal assig ...

The Navy is developing weapon systems capable of launching inert projectiles for long-range surface fire support and missile intercept applications. Inert projectiles offer significant logistical and safety advantages over conventional chemical propellants or explosive ordnances. The launch conditions of future hypersonic projectiles will put extreme mechanical and aerothermal loads on the project ...

ABSTRACT: In Phase I, CFDRC in partnership with ESI, have developed and validated a physics-based CFD tool to quantify fuel spurt caused by impact and penetration of fuel tanks. CFD tool development, qualification and validation study showed good correlations with experiments in terms of fundamental physics including: a) droplet formation, breakup, size, timing and distribution; b) cavitation zone ...

A key challenge toward future directed energy systems is the development of power and thermal management technologies needed to support the laser systems, particularly pump diodes.I2C Solutions and the University of Colorado have developed a Thermal Ground Plane (TGP) technology that interfaces with doide laser bars in order to spread heat and transport it to the laser cooling loop.During Phase II ...

Theoretical computing speeds have increased dramatically in the last decade with chip advances, including Graphics Processor Units (GPUs).In practice, however, these gains have not been realized, largely due to the accompanying high development costs due to the need for multiple code bases to take advantage of the various chips and their variants.The proposed project addresses these issues from bo ...

The amazing ability of humans to recognize a wide variety of sounds with minimal exposure to the myriad of subtle nuances and possible variations of these sounds has driven intense research into modeling the neurobiological processes of hearing over the last 25 years. The field of study focused on processes in the early auditory system and primary auditory cortex has made substantial advancements ...

ColdQuanta proposes the development, fabrication, testing and demonstration of a free-space microshutter based on MEMS technology. The microshutter head will provide extinction ratios exceeding 70 dB and shutter transition times below 10 us, and it will be smaller than any other free space shutter technology currently available. The proposed shutter leverages prior experience with the successful d ...

Decisions made at concept design have profound impacts on total life cycle cost. The industry trend is to apply automated software tools during concept design so larger numbers of alternatives can be evaluated and optimal, feasible solutions identified. Current ship concept design software tools lack the ability to synthesize physical layouts for shipboard distribution systems. Without sized and l ...
