 | Public Law 108-106, as amended, requires that the Special Inspector General for Iraq Reconstruction (SIGIR) prepare a final forensic audit report on all funding appropriated for the reconstruction of Iraq, which to date totals about $50 billion. This is the first in a series of interim reports on the methodology and results of SIGIR's forensic auditing efforts. This report presents the methodology and results to data of our forensic audit ... |

| This report documents the design and construction of a low temperature scanning tunneling microscope optimized for the study of superconductors. The microscope was first used to study the vortex liquid state in the cuprate high-Tc superconductor Bi2Sr2Cu06+x. This work distinguished between a homogenous superconducting gap and an additional inhomogenous 'pseudogap' which may be linked to an alternative electronic ordered state. The microscope then performed the first atomic resolution, high-field investigation ... |

 | Visual evoked responses (VER) from different interpretations of reversible figures, simple geometrical forms, and consonant-vowel-consonant (cvc) trigrams with differently ordered consonants were studied over a 2-year period in three adult human subjects. Stimuli were all black line figures subtending less than 2 degrees, seen against a white, square, 10-degree background and presented in random order with a random interstimulus interval. VERs were obtained from six active electrode sites. VER wave ... |

| The 111th Congress may consider legislation to renew, modify, or reauthorize the Export Administration Act (EAA). In the 110th Congress, several pieces of legislation were introduced that addressed various aspects of the current system, including penalties, enforcement, diversion or transhipment of goods, and the integration of export control data into the Automated Export System, yet no comprehensive reauthorization or reform was attempted. Through the EAA, Congress delegates to the executive ... |

|
| We have developed a combined statistical-dynamical prediction scheme to predict the probability of tropical cyclone (TC) formation at daily, 2.5 degree horizontal resolution across the western North Pacific at intraseasonal lead times. Through examination of previous research and our own analysis, we chose five variables to represent the favorability of the climate system to support tropical cyclogenesis. These so-called large-scale environmental factors (LSEFs) include: low-level relative vorticity, sea surface temperature, ... |

| The America COMPETES Act (P.L. 110-69) responds to concerns that the United States may not be able to compete economically with other nations in the future due to insufficient investment today in science and engineering research and in science, technology, engineering, and mathematics (STEM) education. A similar concern led President Bush to announce the American Competitiveness Initiative (ACI) in January 2006. FY2008 appropriations met neither the Administration's ACI target nor ... |

| Wave propagation in the high frequency regime can be simplified using the geometrical optics approximation. We obtained an eikonal approximation for the phase and transport equations for the amplitude. The general strategy used to find the phase is to solve for its level sets, called wave fronts. This same strategy works to compute semiclassical solutions of Schrodinger's equation, which is the main topic we studied here. Traditional obstacles faced in ... |

| 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 image quality and visibility of the crystal planes in a TEM sample directly relate to how we initially cleave the wafer during the sample preparation process. For diffraction-contrast imaging, many defects and other crystalline features are orientation specific, and are only visible along certain zone axes. The resolution limits of the TEM dictate the preferred zone axes for phase-contrast imaging. The TEM Sample Scribing Template described here allows easy ... |

| We have developed a new and innovative technique for combining a high-spatial-resolution multispectral image with a lower-spatial-resolution hyperspectral image. The approach, called CRISP, compares the spectral information present in the multispectral image to the spectral content in the hyperspectral image and derives a set of equations to approximately transform the multispectral image into a synthetic hyperspectral image. This synthetic hyperspectral image is then recombined with the original low-spatial-resolution hyperspectral image ... |

| This report describes the approach used to compute the down-range and cross-range resolution for the U.S. Army Research Laboratory synchronous impulse reconstruction (SIRE) radar. The results determine the upper bound in term of resolution that the radar can achieve (for targets along the center line of the physical receiving antenna array). These results are needed for the computation of the calibration factor for this radar. |

Few such interbranch disputes over access to information have reached the courts for substantive resolution, the vast majority achieving resolution through political negotiation and accommodation. It was not until the Watergate-related lawsuits in the 1970s seeking access to President ... |

The measurements are made using a sputtering diagnostic based on a quartz crystal microbalance (QCM). The QCM measurement allows full angular resolution, i.e. differential sputtering yield measurements are measured as a function of both polar angle and azimuthal angle. Measured profiles are presented for 100, 250, 350 ... |

| This thesis produces models of satellite constellations using finite state automata (FSA) or finite automata (FA) and optimizes the sequence of targets for two missions. Two simplified FSA models of satellite constellations with one ground control station (GCS) are developed. The first model is of a single spacecraft and the second includes two spacecraft. Based upon the language states and state transitions of each model the author transforms the FA ... |

| A new approach for the clear air velocity estimation in weather radar is presented. A combination of nonparametric with parametric spectral analyses allows us to identify and extract multiple processes caused by different scatterer types within a single radar resolution volume. An example of clear air observed using an S-band dual polarization radar is presented. Heretofore, migrating birds and wind-blown insects that are mixed within each resolution volume caused such ... |
