Cropland Field Monitoring: MMV Page 1 Montana Cropland Enrolled Farm Fields Carbon Sequestration Field Sampling, Measurement, Monitoring, and Verification: Application of Visible-Near Infrared Diffuse Reflectance Spectroscopy (VNIR) and Laser-induced Breakdown Spectroscopy (LIBS)

Description: There is growing need for rapid, accurate, and inexpensive methods to measure, and verify soil organic carbon (SOC) change for national greenhouse gas accounting and the development of a soil carbon trading market. Laboratory based soil characterization typically requires significant soil processing, which is time and resource intensive. This severely limits application for large-region soil characterization. Thus, development of rapid and accurate methods for characterizing soils are needed to… more

Final Report - Independent Verification Survey Activities at the Seperations Process Research Unit Sites, Niskayuna, New York

Description: The Separations Process Research Unit (SPRU) complex located on the Knolls Atomic Power Laboratory (KAPL) site in Niskayuna, New York, was constructed in the late 1940s to research the chemical separation of plutonium and uranium (Figure A-1). SPRU operated as a laboratory scale research facility between February 1950 and October 1953. The research activities ceased following the successful development of the reduction oxidation and plutonium/uranium extraction processes. The oxidation and extr… more

On Direct Verification of Warped Hierarchy-and-FlavorModels

Description: We consider direct experimental verification of warped models, based on the Randall-Sundrum (RS) scenario, that explain gauge and flavor hierarchies, assuming that the gauge fields and fermions of the Standard Model (SM) propagate in the 5D bulk. Most studies have focused on the bosonic Kaluza Klein (KK) signatures and indicate that discovering gauge KK modes is likely possible, yet challenging, while graviton KK modes are unlikely to be accessible at the LHC, even with a luminosity upgrade. We… more

Cost Avoidance vs. Utility Bill Accounting - Explaining theDiscrepancy Between Guaranteed Savings in ESPC Projects and UtilityBills

Description: Federal agencies often ask if Energy Savings PerformanceContracts (ESPCs) result in the energy and cost savings projected duringthe project development phase. After investing in ESPCs, federal agenciesexpect a reduction in the total energy use and energy cost at the agencylevel. Such questions about the program are common when implementing anESPC project. But is this a fair or accurate perception? Moreimportantly, should the federal agencies evaluate the success or failureof ESPCs by comparing … more

Methods to model-check parallel systems software.

Description: We report on an effort to develop methodologies for formal verification of parts of the Multi-Purpose Daemon (MPD) parallel process management system. MPD is a distributed collection of communicating processes. While the individual components of the collection execute simple algorithms, their interaction leads to unexpected errors that are difficult to uncover by conventional means. Two verification approaches are discussed here: the standard model checking approach using the software model che… more

Nuclear Proliferation Using Laser Isotope Separation -- Verification Options

Description: Two levels of nonproliferation verification exist. Signatories of the basic agreements under the Nuclear Non-proliferation Treaty (NPT) agree to open their nuclear sites to inspection by the IAEA. A more detailed and intrusive level was developed following the determination that Iraq had begun a nuclear weapons development program that was not detected by the original level of verification methods. This level, referred to as 93+2 and detailed in model protocol INFCIRC/540, allows the IAEA to do… more

A preliminary study of extraction solvents for CW-agents and their decomposition products [3:1 (methylene chloride:isopropanol) vs. methylene chloride]

Description: The major focus of this study was to explore the possibility of using different extraction solvents (or solvent combinations) to isolate CW agents and their degradation products from environmental and industrial samples. The general approach for extracting, e.g. water samples, required the use of a 3:1 (methylene chloride:isopropanol) extraction solvent. Although the 3:1 solvent extraction work-up methods provided excellent results in several Inter-laboratory Comparison Tests, the implementatio… more
