Deep-ultraviolet (UV) Raman spectroscopy is a powerful method to collect chemically specific information about complex samples because deep-UV (?? < 250 nm) excitation shows an over 200-fold greater efficiency compared to commonly used 785 nm excitation and has the ability to avoid fluorescence background in the Raman spectra. The availability of compact, robust, and reliable deep-UV laser source ...

The recent increase in cyber attacks against United States critical assets has greatly expanded the need for effective cyber defenses. Human cyber analysts are an essential element in these efforts. Information overload and a concomitant lack of comprehensive cyber situation awareness are common problems that hamper the effectiveness of analysis. Systems that can carry out human-in-the-loop simula ...

Most liquid high-level nuclear waste is currently being immobilized to a solid form as a borosilicate glass by vitrification. However, many nuclear wastes have complex and diverse chemical compositions that reduce their compatibility with borosilicate glass. The current baseline spent nuclear fuel reprocess generates secondary waste streams that generally include large amounts of MoO3 and lanthani ...

Solid state lighting has not yet taken off in commercial buildings due to its high relative installed cost. On a normalized basis, solid state lighting replacement lamps are on the order of two times more expensive than equivalent compact fluorescent lamps (CFLs), and five times more expensive than an equivalent downlight fixture. An additional barrier relates to the performance and cost of the dr ...

The objective of this program is to develop a troop restraint system that is easier, more intuitive, and quicker to install than current systems, while providing improved restraint over the current four- and five-point systems. The program consists of a six-month effort to develop critical components of the system and to produce a prototype design. In the four-month option, prototype systems will ...

DESCRIPTION provided by applicant Amyotrophic lateral sclerosis ALS or Lou Gehrigandapos s disease is a fatal neurodegenerative disease with a typical lifespan of years after diagnosis The initial symptoms can be similar to many other neurologic disorders and often begin with limb weakness muscle fasciculations or increasing difficulties in speech or breathing No definitive diagnost ...

ABSTRACT: Both commercial and military aircraft are being flown/utilized for extended operational time. The aircraft cumulative flight hours often times extends the original design limits. Each different aircraft manufacturer calculates aircraft fatigue and damage using different techniques. A more accurate prediction of remaining life and inspection interval for an individual aircraft is require ...

Transparent armor is very important to the survivability and situational awareness for the crews of modern land, marine or aviation vehicles. Additionally to the common armor requirements (low areal density and high ballistic performance) transparent armor should provide high infrared and visual transmittance. Ceramic ballistic windows meet these requirements, but they often suffer from unaffordab ...

A multi-band dual-aperture SATCOM antenna is proposed to support rotary-wing aircraft thru-rotor performance at X, Ku and Ka-bands including Ku-band TCDL as an option. Our proposed effort focuses on a low-cost design with reduced height and leverages existing aperture and radome technology from our prime contractor partner Lockheed-Martin. It also leverages existing digital modem technology develo ...

Using a small, cost-effective, expendable Tier I UAV specifically engineered for magnetic anomaly detection will be an effective way to augment the P8-A HAASW capabilities. Tier I UAVs offer many advantages over larger Tier II UAVs for this mission. The main ones being their lower costs and expendability. The primary challenges with using a small Tier I UAV for ASW missions are the development of ...
