ABSTRACT:Cognitive skills/capabilities are important for the military personnel to fulfill tasks and to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. Although models to predict the tDCS curren ...

ABSTRACT:A cooperative small business and university research and development program is proposed to begin development of a robust, non-contacting, digital image correlation based, full-field strain measurement system for high temperature applications. The Phase I studies will demonstrate that a robust high temperature digital image correlation system (HTDICS) can be developed that is capable of a ...

ABSTRACT:Modulator linearity and efficiency, in addition to bandwidth, are important parameters in characterizing a modulator. In general, improving modulation efficiency is highly desirable since higher modulation efficiency allows lower RF signal to impose equivalent change in the optical beam whereas improved linearity increases the dynamic range available to analog signals conveyed and process ...

ABSTRACT:Hyperspectral imaging is a technique used to simultaneously capture spatial and spectral information of an object scene, making it a valuable technique for applications in remote sensing and military battlefield environments. In the case of long wave infrared (LWIR) imaging, a hyperspectral approach offers an opportunity to improve upon the detection capabilities of standard broadband sen ...

ABSTRACT: Under the proposed effort, PSI will leverage a novel pmmW imaging technology developed under a prior Navy program to realize the low size, weight, and power sensors required for UAV implementation. This technology is based on an optical upconverted distributed aperture technology that can make use of the full aperture of the aircraft thereby maximizing achievable resolution. This sensor ...

We will evaluate a novel warming method, developed by our collaborator John Bischof, that promises solution of one of the remaining barriers for banking of large organs and vascularized composite tissues. The method involves radiofrequency and magnetic nanoparticles to obtain rapid uniform electromagnetic rewarming of biological materials instead of warming from the outer boundary using convection ...

The long term goal of the proposed research is to develop improved methods for cryopreservation of complex tissues at extreme low temperature. An innovative approach is taken in the proposed line of research, where synthetic ice modulators (SIMs) are combined with established cryoprotective agent (CPA) cocktails to create more favorable conditions for cryopreservation in a process known as vitrifi ...

ABSTRACT:In this phase II effort we will commercialize the high speed, high power, modified uni-traveling carrier (MUTC) photodiodes (PDs). To this end, we will develop reliable packaging solutions for discrete PDs, PD arrays, balanced PDs and waveguide based PDs. We will also transition the chip fabrication process for continuous, high volume supply of quality MUTC PD chips. In the first six mont ...

THE HOSTILE ENVIRONMENT EXISTING AT THE BORE SURFACE OF GUN BARRELS USED IN HIGH RATE OF FIRE AIRCRAFT CANNONS PRESENTS A FORMIDABLE DESIGN CHALLENGE TO THE GUN DESIGNER. HEAT, FRICTION, CORROSION AND WEAR AT THE BORE SURFACE ACT IN UNISON TO RAPIDLY DETERIORATE THE BORE. CHROME PLATING IS PRESENTLY THE ONLY COST EFFECTIVE METHOD OF IMPROVING BORE SURFACE LIFE. PLASMA SURFACE ALLOYING IS AN EMERGI ...
