 | We have developed a new type of microplasma integrated device with a fabric structure of insulator-coated thin metal wires. It has been proved that the device can be operated at relatively low voltage of a few kV in air and even under water with the help of hydrogen bubbles produced by electrolysis of water. We have performed spectroscopic measurements for characterizing the properties of microplasmas in a single jet and ... |

| Iran is materially assisting major Shiite Muslim political factions in Iraq, most of which have longstanding ideological, political, and religious ties to Tehran, and their armed militias. In late 2007, the Administration noted a decrease in Iranian weapons shipments, but there is debate in the Administration over whether this was driven by U.S. policy toward Iran, including interdiction as well as bilateral diplomacy on Iraq stabilization, or an Iranian re-evaluation ... |

| This report reviews North Korea's ballistic missile program. In summer 2007, North Korea tested modern, short-range missiles. In July 2007, a Pentagon official said North Korea was about to deploy a new, advanced short-range missile, designated the KN-02, or Toksa (said to be a derivative of the former Soviet SS-21 missile). This report will be updated periodically. Additional information is provided by CRS Report RL33590, North Korea s Nuclear Weapons ... |

| Authors:
Mark J. Balas; Casey Fagley; WYOMING UNIV LARAMIE DEPT OF ELECTRICAL AND COMPUTER ENGINEERING
|
| Control of large-scale, aero-elastic models requires advanced model reduction techniques for implementation of feedback control. New reduced order model techniques must be developed based on the concepts and physics of fluid-structure interaction. Current methods are inefficient and inaccurate when dealing with these large scale aero-elastic models. Reduced order model (ROM) based controllers may produce adverse affects on un-modeled modes causing instability in the system. The idea of compensation is introduced ... |

| In the years leading up to the terrorist attacks of September 11, 2001, the United States lacked a comprehensive national policy and strategy for aviation security. The approach to aviation security was largely shaped by past events, such as the bombing of Pan Am flight 103 in December 1988, rather than a comprehensive evaluation of the full range of security risks. The 9/11 Commission concluded that the terrorist attacks of ... |
