The video surveillance industry is experiencing dramatic change with the move from analog to digital video. Command centers need to have coordinated viewing of multiple camera feeds at one time, and the ability to switch automatically between feeds and display relevant patterns. Conventional security control rooms include a bank of monitors connected through a switch to an array of security camera ...

The proposed effort can provide the framework for a unified modeling & simulation program to substantially improve the capability for understanding, analyzing, and predicting the underlying mechanisms dictating the combustion stability characteristics of liquid-propellant rocket engines. Emphasis will be placed on the effects of atomization, mixing, and distributed combustion of liquid oxygen (LO ...

Combustion instability in liquid rocket engines (LREs) has manifested in nearly all LRE development programs. While the driving mechanisms of combustion instability are vast and coupled, in all instances, the net result is significant cost and schedule over-runs. In today’s business environment, such over-runs are rarely tolerated and generally result in program cancellations. Development of hig ...

This Small Business Technology Transfer Program Phase I objective is twofold. During both depot and field repair operations the coating system is removed using mechanical and chemical stripping methods that result in removal of some of the metallic cladding. The removal of the cladding during paint stripping makes the underlying high strength aluminum alloy more prone to corrosion. Thus, the fi ...

NextGen is partnering with Virginia Commonwealth University (VCU) to develop tiny energy harvesting modules exploiting variation/fluctuation in ambient temperature with time. Our team is proposing to improve electric power generation by an order of magnitude over state-of-the-art thermoelectric power-converters by using pyro-piezoelectric properties of ferroelectric materials. We are proposing thi ...

Ammonium perchlorate (AP) is the most commonly used oxidizing ingredient in solid propellant formulations. It carries a sufficient excess of oxygen to allow for the combustion of the required binder and added metal, such as aluminum. One major drawback of AP is its chlorine content which results in the formation of hydrochloric acid (HCl) as a combustion product and can cause environmental probl ...

Ammonium perchlorate (AP) is the most commonly used oxidizing ingredient in solid propellant formulations. It carries a sufficient excess of oxygen to allow for the combustion of the required binder and added metal, such as aluminum. The major drawback of AP is its chlorine content which results in the formation of large amounts of HCl as a combustion product and causes severe environmental proble ...

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 ...

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 ...

The objective of this proposal is to develop and validate a methodology for obtaining accurate, reliable and transferable force fields for a variety of ionic liquids (ILs) including those designed for lubrication, gas generation, energy storage and as energetic materials. The methodology involves development of a hierarchy of force fields through reduction of degrees of freedom in a statistical me ...
