Among the factors that inhibit the use of composite materials in both general aviation aircraft and DoD platforms are the high cost of engineering and the cost of certification. Unless manufacturers can control risk when introducing new materials and pro

There is a clear gap between commercially available UHF tunable filters and the technology needs of current military communication systems. MEMtronics Corporation, teamed with Purdue University, intend to develop and commercialize technology that fills this gap. The intent of this Phase II project is continue the successful demonstrations began in Phase I and bring the technology to a level of ma ...

With the need to attract and retain students to the science, technology, engineering, and math (STEM) fields, it is important to capture students'interest as early as possible. There are student robotics programs around the nation that appear to provide great excitement for students. These robots require skills in programming and logic, which may be difficult for a first-time programmer. Vide ...

Looking Glass is an immersive, story-driven game experience that enables computer science education for students K-12. It presents learning in a game-based series of challenge levels that permit a high degree of player choice in tailoring educational progression and adapting game systems that present both STEM and SEL interactions. Gameplay occurs within a futuristic Wonderland, where proficiency ...

The survivability of vehicles and aircraft is greatly dependent on their mobility and level of armor protection. In most cases, mobility is best served by minimizing mass. Conversly, the level of protection afforded by an armor system is usually directly proportional to its mass. This leads to the difficult trade off of protection versus mobility. There- fore, armor systems with increased levels o ...

At present, the only fuel cell systems that have the capability of achieving high power den W cm-2) are the proton exchange membrane (PEM) and the alkaline fuel cell (AFC) systems. Of these, the PEM system is the leading candidate fuel cell power source for many military and commercial applications. In order to make PEM fuel cell power sources cost-competitive with competing technologies and more ...

At present, four classes of structural adhesives (epoxy resins, phenolic resins, acrylic adhesives and urethanes) are commonly employed in applications where the adhesive joint is either totally immersed in salt or fresh water or subject to high levels of moisture while simultaneously experiencing large shear loads. Each of these synthetic polymer formulations suffers from individual disadvantages ...

Water is one of the basic commodities which will be needed in ever increasing quantities as industrialization and urbanization of the world progresses presenting many new challenges for the water processing industry. As new industrial products have been developed and manufactured with increasing complexity and sophistication so has the need for increasing the purity of the processing water that is ...

Millimeter-wave system designers are limited to two terminal devices when high powers are required from a solid state device. InGaAs/InAlAs HEMTs latticed matched to InP substrates have produced excellent low noise results at millimeter-wave frequencies. The high power performance, however, is limited by the narrow bandgap of the InGaAs chamel which leads to low breakdown voltages between the drai ...
