 | In November 2003, the Congress passed Public Law 108-106, the Emergency Supplemental Appropriations Act for Defense and for the Reconstruction of Iraq and Afghanistan, 2004, which created the $18.4 billion Iraq Relief and Reconstruction Fund (IRRF). In addition to providing funding for Iraq reconstruction, the law contained a requirement to submit reports to the Congress on how the funding was being used, and provided $50 million to be used to ... |

| Multi-core processing technology has been developing rapidly and multi-core solutions are becoming increasingly prevalent in industry. The potential impact and disruption of multi-core technologies to centralized computationally intensive applications, such as engine control, may be significant. With the ability to efficiently partition code between separate processing elements, whilst sharing a common I/O space, a new generation of process partitioning, a thread pipelining becomes possible. In this paper we briefly summarize ... |

| The Internet's continuing growth, stability, and security are vital to the Department of Defense's (DoD) mission. While the DoD no longer controls Internet decision making, its unique perspective deriving from its multiple roles as Internet user, operator, and research center is important to the development and protection of U.S. national interests. It should make a commitment to participate directly in international Internet decision-making forums, as well as actively develop policy ... |

| The Unified Cross Domain (CD) Management Office (UCDMO) was established July 2006 to address the needs of the DoD and the IC to share information and bridge disparate networks. Information sharing is a requirement that spans both departments and requires the ability to share information from the most highly classified networks to the most open coalition networks. The UCDMO was created to address the duplication, inefficiencies and resulting ineffectiveness resulting ... |

| The Department of Defense's (DoD) policy, planning, and warfighting capabilities are heavily dependent on the information technology foundation provided by the Global Information Grid (GIG). However, the GIG was built for business efficiency instead of mission assurance against sophisticated adversaries who have demonstrated intent and proven their ability to use cyberspace as a tool for espionage and the criminal theft of data. GIG mission assurance works to ensure the DoD ... |

| Often called the "holy grail" of network management is the problem of how to provide automated support in detecting computer network outages and degradations. Current methods for this type of problem are mostly manual in nature. Network Management Services technologies allow increased visibility and control but cannot relate network status to mission capabilities as the information is simply not present in the network. Goal of research presented is to create ... |

| On May 14, 1948, the State of Israel declared its independence and was immediately engaged in a war with all of its neighbors. Armed conflict has marked every decade of Israel's existence. Despite its unstable regional environment, Israel has developed a vibrant parliamentary democracy, albeit with relatively fragile governments. The Kadima Party placed first in the March 28, 2006, Knesset (parliament) election; Prime Minister Ehud Olmert formed a coalition government. ... |

| A generic nonlinear dynamic range compression deconvolver (DRCD) is proposed. We have performed the dynamic range compression deconvolution using three forms of nonlinearities: (1) digital implementation- A-law/ -law, (2) hybrid digital-optical implementation- two-beam coupling photorefractive holography, and (3) all optical implementation- MEMS deformable mirrors. The performance of image restoration improves as the saturation nonlinearity increases. The DRCD could be used as a preprocessor for enhancing Automatic Target Recognition (ATR) system ... |

| A novel spectral imaging sensor based on dual direct vision prisms is described. The prisms project a spectral image onto the focal plane array of an infrared camera. The prism set is rotated on the camera axis and the resulting spectral information is extracted as an image cube(x, y, 1), using tomographic techniques. The sensor resolves more than 40 spectral bands (channels) at wavelengths between 1.2 microns and 2.5 microns ... |

| Social network analysis frequently uses the idea of a clique in a network to identify key subgroups of highly-connected members of the network. We formulate the maximum clique problem on undirected graphs and develop two algorithms to solve it: a pruning algorithm and an enumeration algorithm. The pruning algorithm successively improves an upper bound on the clique number of a graph, and the enumeration algorithm successively finds larger and larger ... |

|
| The global Internet is a federation of computer networks that are owned and operated by Internet Service Providers (ISPs). Because ISPs do not share topology information for competitive and privacy reasons, researchers, operators, and policy makers who want to assess the performance and reliability of the system as a whole must infer structure from limited measurement data. We use reverse-engineering to infer underlying design principles of a national ISP and ... |

| The trust literature emphasizes trust in automation (Lee & See, 2004), thus neglecting the interpersonal aspects of how distributed personnel develop trust. Interpersonal trust represents the willingness of individuals to accept vulnerabilities from the actions of others (Mayer, et al., 1995). Vulnerability is critical aspect of trust research, yet few studies have manipulated vulnerability. Non-verbal cues may have an influence on the trust process (Wicks, et al., 1999), suggesting that ... |

These include the ability to get going with their mission with minimal infrastructure tight-loop and frequent communication, light-weight equipment, ability to scale-up the team when needed, and finally, the longest-running and lightest power source for their equipment. We present a system called TwiddleNet, which harnesses the power ... |

| The role of computer networked operations (CNO) has taken on greater importance with the rise of network-centric warfare. Comprised primarily of defense, attack, and exploitation, the technological capabilities are growing exponentially, as is the rate of data exchange, yet the organizational configurations supporting CNO are slow to anticipate and react. This presents a serious issue in terms of command and control (C2), as such organizations do not fit well with ... |

| X-ray computed microtomography (XMT) is used for high-resolution, nondestructive imaging and has been applied successfully to geologic media. Despite the potential of XMT to aid in formation evaluation, currently it is used mostly as a research tool. One factor preventing more widespread application of XMT technology is limited accessibility to microtomography beamlines. Another factor is that computational tools for quantitative image analysis have not kept pace with the imaging technology ... |

| The post-World War II U.S.-Japan alliance has long been an anchor of the U.S. security role in East Asia. The alliance, with its access to bases in Japan, where about 53,000 U.S. troops are stationed, facilitates the forward deployment of U.S. military forces in the Asia-Pacific, thereby undergirding U.S. national security strategy. For Japan, the alliance and the U.S. nuclear umbrella provide maneuvering room in dealing with its neighbors, particularly ... |
