Application of Low-Cost Digital Elevation Models to Detect Change in Forest Carbon Sequestration Projects
This two-year study evaluated advanced multispectral digital imagery applications for assessment of forest carbon stock change. A series of bench and field studies in North Carolina and Ohio tested aerial assessments of forest change between two time periods using two software packages (ERDAS and TERREST) for Digital Elevation Model (DEM) creation, automated classification software (eCognition) for canopy segmentation and a multiple ranging laser designed to improve quality of elevation data. Results of the DEM software comparison showed that while TERREST has the potential to produce much higher resolution DEM than ERDAS, it is unable to resolve crucial canopy features adequately. Lab tests demonstrated that additional laser data improves image registration and Z-axis DEM quality. Data collected in the field revealed difficult challenges in correctly modeling the location of laser strike and subsequently determining elevations in both software packages. Automated software segmentation of tree canopies provided stem diameter and biomass carbon estimates that were within 3% of comparable ground based estimates in the Ohio site and produced similar biomass estimates for a limited number of plots in the Duke forest. Tree height change between time periods and canopy segmentation from multispectral imagery allowed calculation of forest carbon stock change at costs …

Aviation Security: Federal Coordination for Responding to In-flight Security Threats Has Matured, but Procedures Can Be Strengthened
Correspondence issued by the Government Accountability Office with an abstract that begins "Five years after the terrorist attacks of September 11, 2001, concerns continue to be raised about the nation's system for protecting commercial aviation. Past disclosures of terrorists' plans for smuggling liquids onboard aircraft to construct a bomb in flight highlighted the continued need to examine this key aspect of homeland security. One layer of the aviation security system involves the ability of the federal government to respond to actual or potential security threats while a commercial aircraft is in flight. These security threats can include the following: (1) Passengers considered to be security risks to aviation are found to be onboard flights bound for or leaving the United States. (2) Situations develop while the aircraft is in flight--for example, a passenger becomes disruptive or acts suspiciously, a bomb threat is received, or an unidentified package is found onboard the aircraft. (3) A commercial aircraft transmits a signal designed to alert authorities that a hijacking is in process. Procedures for addressing these in-flight security threats involve a wide range of federal agencies and entities. The Department of Homeland Security (DHS) is responsible for taking much of the lead in …

Border Security: Security of New Passports and Visas Enhanced, but More Needs to Be Done to Prevent Their Fraudulent Use
A letter report issued by the Government Accountability Office with an abstract that begins "Travel documents are often used fraudulently in attempts to enter the United States. The integrity of U.S. passports and visas depends on the combination of well-designed security features and solid issuance and inspection processes. GAO was asked to examine (1) the features of U.S. passports and visas and how information on the features is shared; (2) the integrity of the issuance process for these documents; and (3) how these documents are inspected at U.S. ports of entry. We reviewed documents such as studies, alerts, and training materials. We met with officials from the Departments of State, Homeland Security, and Commerce's National Institute of Standards and Technology, and U.S. Government Printing Office, and with officials at seven passport offices, nine U.S. ports of entry, two U.S. consulates in Mexico, and two Border Crossing Card production facilities."

Capitol Visitor Center: Update on Status of Project's Schedule and Cost as of July 31, 2007
Testimony issued by the Government Accountability Office with an abstract that begins "Since the June 27, 2007, Capitol Visitor Center (CVC) hearing, the project's construction has progressed, and according to the latest schedule, Architect of the Capitol (AOC) is still projecting a June 27, 2008, completion date and a September 22, 2008 opening date. Work has advanced on the project's heating, ventilation, and air-conditioning (HVAC) system, interior wall stone and ceiling installation, and other interior and exterior construction work. However, some delays have occurred in activities on the project's critical path (i.e., the work on the fire alarm system) and on most of its near-critical paths, and further delays are possible. AOC was able to mitigate the delay in the project's critical path by reducing the time available for future fire alarm testing. This action may not produce the desired results, though, given the complexity of the requirements for fire alarm testing. Delays in near-critical activities such as the ceiling close-ins and the House and Senate expansion spaces have reduced the time reserved for contingencies along those near-critical paths, but have not yet affected the critical path. Furthermore, a number of risks to the project's schedule remain. These include potential …

The Child Tax Credit
The child tax credit was enacted in 1997, as Congress addressed concerns that the income tax structure did not adequately reflect a family's reduced ability to pay taxes as family size increased. Subsequent changes in 2001, 2003, and 2004 increased the child tax credit and made it refundable for most families. This report covers current law, legislative history, policy issues, and analysis as well as related information regarding the child tax credit and refund.

Contol of Surface Mounted Permanent Magnet Motors with Special Application to Motors with Fractional-Slot Concentrated Windings
A 30-pole, 6-kW prototype of a fractional-slot permanent magnet synchronous motor (PMSM) design has been developed to operate at a maximum speed of 6000 rpm [1,2]. This machine has significantly more inductance than regular PMSMs with distributed windings. The prototype was delivered in April 2006 to the Oak Ridge National Laboratory (ORNL) for testing and development of a suitable controller. To prepare for this test/control development effort, ORNL used PMSM models developed over a number of previous studies to preview the control issues that arise when a dynamic controller drives a high inductance PMSM machine during steady state performance evaluations. The detailed steady state model developed includes all motor and inverter loss mechanisms and was useful for assessing the performance of the dynamic controller before it was put into operation. This report documents the results of tests demonstrating the effectiveness of ORNL's simple low-cost control scheme during characterization of the fractional-slot concentrated windings (FSCW) PMSM motor. The control scheme is simple because only the supply voltage magnitude and the phase angle between the back-electromotive force (emf) and the supply voltage is controlled. It is low-cost because it requires no current or phase voltage sensors.

Defense Contract Management: DOD's Lack of Adherence to Key Contracting Principles on Iraq Oil Contract Put Government Interests at Risk
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense's (DOD) U.S. Army Corps of Engineers (Corps) awarded the $2.5 billion Restore Iraqi Oil (RIO I) contract to Kellogg Brown & Root in March 2003 in an effort to reestablish Iraq's oil infrastructure. The contract was also used to ensure adequate fuel supplies inside Iraq. RIO I was a cost-plus-award-fee type contract that provided for payment of the contractor's costs, a fixed fee determined at inception of the contract, and a potential award fee. The Defense Contract Audit Agency (DCAA) reviewed the 10 RIO I task orders and questioned $221 million in contractor costs. We were asked to determine (1) how DOD addressed DCAA's RIO I audit findings and what factors contributed to DOD's decision and (2) the extent to which DOD paid award fees for RIO I and followed the planned process for making that decision. To accomplish this, we reviewed DOD and DCAA documents related to RIO I and interviewed Corps, DCAA, and other officials."

Defense Health Care: Under TRICARE, Children's Hospitals Paid More Than Other Hospitals After Accounting for Patient Complexity
A letter report issued by the Government Accountability Office with an abstract that begins "Under the Department of Defense's (DOD) TRICARE health program, hospitals that treat primarily children--designated by DOD as children's hospitals--are paid differently from other types of civilian hospitals through a children's hospital differential payment. Representatives of children's hospitals state that payments for children's hospital services do not fully recognize the higher complexity of children's hospital patients. Acknowledging concerns over payments for children's hospital services, the National Defense Authorization Act for Fiscal Year 2006 directed GAO to study DOD's current system of payments to children's hospitals. This report examines (1) the effect of the differential on TRICARE's base payments to children's hospitals, (2) differences in diagnosis and complexity between TRICARE pediatric patients at children's hospitals and those at other hospitals, (3) the extent to which TRICARE payment differences across hospitals reflect differences in patient complexity, and (4) recent trends in TRICARE pediatric patients' use of children's hospital services. To do this, GAO analyzed pertinent TRICARE claims data for fiscal years 2003 through 2006 and interviewed relevant DOD officials and representatives of children's hospitals."

Design of Complex Systems in the presence of Large Uncertainties: a statistical approach
The design or optimization of engineering systems is generally based on several assumptions related to the loading conditions, physical or mechanical properties, environmental effects, initial or boundary conditions etc. The effect of those assumptions to the optimum design or the design finally adopted is generally unknown particularly in large, complex systems. A rational recourse would be to cast the problem in a probabilistic framework which accounts for the various uncertainties but also allows to quantify their effect in the response/behavior/performance of the system. In such a framework the performance function(s) of interest are also random and optimization of the system with respect to the design variables has to be reformulated with respect to statistical properties of these objectives functions (e.g. probability of exceeding certain thresholds). Analysis tools are usually restricted to elaborate legacy codes which have been developed over a long period of time and are generally well-tested (e.g. Finite Elements). These do not however include any stochastic components and their alteration is impossible or ill-advised. Furthermore as the number of uncertainties and design variables grows, the problem quickly becomes computationally intractable. The present paper advocates the use of statistical learning in order to perform these tasks for any system …

Environmental Biosciences Program Quarterly Report
In May 2002, the United States Department of Energy (DOE) signed Assistance Instrument Number DE-FC09-02CH11109 with the Medical University of South Carolina (MUSC) to support the Environmental Biosciences Program (EBP). This funding instrument replaces DOE Assistance Instrument Number DE-FC02-98CH10902. EBP is an integrated, multidisciplinary scientific research program, employing a range of research initiatives to identify, study and resolve environmental health risks. These initiatives are consistent with the MUSC role as a comprehensive state-supported health sciences institution and with the nation's need for new and better approaches to the solution of a complex and expansive array of environment-related health problems. The intrinsic capabilities of a comprehensive health sciences institution enable MUSC to be a national resource for the scientific investigation of environmental health issues. EBPs success as a nationally prominent research program is due, in part, to its ability to task-organize scientific expertise from multiple disciplines in addressing these complex problems Current research projects have focused EBP talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene and low-dose ionizing radiation. Work on the trichloroethylene research projects has been slowed as a result of funding …
