ABSTRACT:A joint experimental and computational project using a carefully designed, flexible test article is proposed to assess the velocity-coupled combustion response of a representative liquid rocket injector element to transverse acoustic disturbances. In the proposed Phase II, the response of an injector flowfield at supercritical pressure conditions will be simulated, measured, and reduced i ...

The proposed SkySight Technologies Quick Release Connector will independently detect an unexpected mechanical load on the power distribution line. The compact and lightweight SkySight Quick Release Connector uses existing methods and hardware to integrate into the infrastructure, and no special tools or skills are required. While the connector can be latched by hand without any special tools, it c ...

Two methods for analyzing software security risks are dynamic application security testing (DAST) - an outside in perspective - and static application security testing (SAST) - and inside out perspective. Both have shortfalls. DAST findings do not give insight into the root cause, making remediation time consuming. SAST tools give you full breadth, but warn of weaknesses that are not exploitable. ...

The project team is developing a prototype of a web-based game utilizing the illustrations of chemical elements and science terms created by Simon Basher in his three books, The Periodic Table: Elements with Style!, Chemistry: Getting a Big Reaction!, and Physics: Why Matter Matters! The game will incorporate augmented reality (person-to-person gameplay with the support of the software) to teach g ...

GoGames will be a tablet-based multiplayer role-play game for middle school social studies classrooms and will focus on topics in civics. GoGames is intended to enable more efficient and effective implementation of traditional civics interventions by replacing static paper content and training manuals with dynamic interactive content and key information for gameplay. Modules will include LawMaker, ...

The web-based game, MathFacts, will include a series of apps for touch-screen tablet computers to support math learning for 1st to 4th grade students with major or sometimes intractable learning difficulties. In the game, students will learn content through mini-lessons, engage with problems in practice and speed rounds, and then receive formative feedback on their performance. Students will use ...

Carbon dioxide capture systems are currently being considered to mitigate the increase in atmospheric CO2 concentration caused by fossil fuel combustion. The costs to implement and operate these systems must be reasonable to minimize economic impacts. In particular, the required compression systems will consume significant power, and they will require large capital investment. Advanced technol ...

New Generation IV nuclear power plants are being developed that promise to enable nuclear power to achieve its potential as a large scale source of environmentally benign power generation while improving safety and minimizing proliferation risks. These reactors will need large numbers of metallic fuel pins made from uranium alloys, but existing methods for casting these fuel pins are very costly. ...

In 2011, the US electricity generation was 4344 billion kWh gross with 821 TWh (19%) from nuclear power reactors. The US has 104 nuclear power reactors, 69 pressurized water reactors and 35 boiling water reactors, in 31 states, operated by 30 different power companies. Almost all of the US nuclear generating capacity comes from reactors built between 1967 and 1990. There have been no new construc ...

There are over 350 thousand contaminated sites in the US which will require cleanup by both government and private industry in the next twenty years. The total cost of this environmental site cleanup is estimated to be in the hundreds of billions of dollars. Amongst federal agencies the Department of Energy (DOE) and the Department of Defense (DoD) have the largest cleanup liabilities which amount ...
