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

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 ...

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 ...

THIS PROGRAM'S OBJECTIVE IS TO ESTABLISH THE RELAXOR FERROELECTRIC PB(MG1/2NBS/3)O3 (PMN) AS THE MATERIAL OF CHOICE FOR THIN FILM CAPACITORS IN DRAM AND ELECTRONIC PACKAGING APPLICATIONS.IN CONTRAST TO "NORMAL" FERROELECTRICS, E.G., BATIO3 AND PZT, RELAXORS OFFER HIGH DIELECTRIC CONSTANTS (K>10,000), BROAD PHASE TRANSITIONS,LOW E-FIELD DEPENDENCY OF K, AND LARGE RXC TIME CONSTANTS. IN ADDITION, TH ...

THE PROPOSED EFFORT INITIATES RESEARCH TO DEVELOP A SET OF KNOWLEDGE REPRESENTATION TOOLS ADDRESSING THE UNIQUE NEEDS OF INTERDISCIPLINARY TEAMS OF DOMAIN EXPERTS WHO DESIRE TO CREATE AND MAINTAIN SHARED KNOWLEDGE BASES. THE PROPOSED ART-DEKO (ARTIFACT-DESIGN/ENGINEERING KNOWLEDGE ONTOLOGY) TOOLSET WILL PROVIDE INTELLIGENT ASSISTANCE AND MEDIATION TO EXPERTS IN THE COOPERATIVE PROCESS OF DEFINING ...
