Modern flight simulators utilize combinations of motion, visual stimulation, and occasionally tactile body stimulation. Despite advances in these fields, simulators remain limited in the amount and type of motion simulation they can impart to a pilot. Direct vestibular stimulation can generate continuous sensed motions, and therefore holds promise for improving flight simulators by incorporating ...

Durability is the effect of time dependant processes, including fatigue, creep, moisture absorption, thermal-oxidation, abrasion, chemical reactions and physical ageing on mechanical properties. The ability to predict accurately the durability of composite materials and structures is critical to successfully designing for longevity. The existence of models alone is not sufficient; practical soft ...

We propose to develop high-fidelity numerical simulation tools to be used in the analysis and assessment of bone conduction of sound in the human head and the desigh of noise protection devices. The proposed approach utilizes boundary and volumetric integral equation methods, and will constitute an extension of our currently developed approach from acoustics to coupled elasticity-theory and acou ...

We propose to develop new polymer-ceramic nanoparticle composites for high power capacitors. The new approach combines the leading-edge nanomaterials development and manufacturing at Agiltron will transfer the high dielectric constant fillers to our new nanodielctrics with extremely improved breakdown strength and extensively lowered dielectric loss. We expect to fully overcome the problems of cu ...

It is desirable to make high resolution imagers that simultaneously acquire multispectral information from the same spatial locations; doing so enables a number of target detection and tracking applications. Currently, image resolution is limited by the pixel pitch which cannot be reduced below optical diffraction and carrier diffusion limited values, and by the need to have different pixels resp ...

Morphing aircraft structures have been under focused development over the last five years, primarily under DARPA and Air Force sponsorship. NextGen has been a leader in this effort; prior and on-going work by the NextGen team has identified significant technology barriers which need fundamental understanding as well as innovative solutions. Key among these is the development of skins which have in ...

Physical Sciences Inc. (PSI) and Purdue University (PU) propose to synthesize, characterize, and investigate the efficiency, reactivity, and selectivity of new nanocatalysts in hydrocarbon fuel liquid for RBCC applications. The nanocatalysts will have higher surface area/volume compared to conventional microcatalysts and films, thereby leading to faster reaction rates. Decreased coking will occur ...

The capabilities of current prostheses are substantially limited by the lack of suitable high energy density portable power. Specifically, current myoelectric prostheses utilize rechargeable batteries, which provide typically less than 10% of the daily energy required for typical activities of daily living. Such limitations in the energy source significantly limit the utility of these prostheses ...

Maps are an incredibly rich source of information, but the information contained in a map is often locked up in a raster image. Sometimes the original source data used to create the map is available, but more often than not this information has either been lost or is not available. In the proposed project, we propose to develop the technology that will make it possible to exploit the huge number ...

The Army has an obvious and immediate need for greater exploration of small molecules in the search for novel anti-malarial drugs. The innovative techniques offered in this proposal utilize methods of iterated automated fragment assembly coupled with an intelligent compound screening tool to facilitate scientific advancement. The resulting computational methods can increase the rate and exploratio ...
