Advanced Combustion Diagnostics and Control for Furnaces, Fired Heaters and Boilers (open access)

Advanced Combustion Diagnostics and Control for Furnaces, Fired Heaters and Boilers

The objective of this project was to develop and apply enabling tools and methods towards advanced combustion diagnostics and control of fired-equipment in large-scale petrochemical manufacturing. There are a number of technology gaps and opportunities for combustion optimization, including technologies involving advanced in-situ measurements, modeling, and thermal imaging. These technologies intersect most of manufacturing and energy systems within the chemical industry. This project leveraged the success of a previous DOE funded project led by Dow, where we co-developed an in-situ tunable diode laser (TDL) analyzer platform (with Analytical Specialties Inc, now owned by Yokogawa Electric Corp.). The TDL platform has been tested and proven in a number of combustion processes within Dow and outside of Dow. The primary focus of this project was on combustion diagnostics and control applied towards furnaces, fired heaters and boilers. Special emphasis was placed on the development and application of in-situ measurements for O2, CO and methane since these combustion gases are key variables in optimizing and controlling combustion processes safely. Current best practice in the industry relies on measurements that suffer from serious performance gaps such as limited sampling volume (point measurements), poor precision and accuracy, and poor reliability. Phase I of the project …

Agency for Toxic Substances and Disease Registry: Policies and Procedures for Preparing Public Health Products Should Be Strengthened (open access)

Agency for Toxic Substances and Disease Registry: Policies and Procedures for Preparing Public Health Products Should Be Strengthened

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses the Agency for Toxic Substances and Disease Registry's (ATSDR) policies and procedures for product preparation. ATSDR investigates community exposures related to chemical sites and releases; works with federal, tribal, state, and local agencies to identify potential exposures; assesses associated health effects; and recommends actions to stop, prevent, or minimize these harmful effects. In conducting these activities, the agency publishes many types of public health products, including public health assessments, health consultations, health study reports, and exposure investigations. Recent reports by the Institute of Medicine and ATSDR's Board of Scientific Counselors have identified various concerns such as the appropriateness and quality of the data used in ATSDR's products, the methodology and design of the studies, and clearance policies. This committee has held two previous hearings that focused on its concern about the quality of ATSDR's products. In response, ATSDR has noted that multiple factors have posed challenges for the agency, including limitations in the ability of available science to answer community questions about the effect of chemical exposures, limitations in ATSDR's ability to collect data related to exposures, and reductions since 2004 in the number of …

American Jihadist Terrorism: Combating a Complex Threat (open access)

American Jihadist Terrorism: Combating a Complex Threat

Between May 2009 and August 2010, arrests were made for 19 "homegrown," jihadist-inspired terrorist plots by American citizens or legal permanent residents of the United States. The apparent spike in such activity after May 2009 suggests that at least some Americans - even if a tiny minority - continue to be susceptible to ideologies supporting a violent form of jihad. This report describes homegrown violent jihadists and the plots and attacks that have occurred since 9/11. This report also provides official definitions for terms such as "homegrown," "jihadist," and "violent jihadist." The report also discusses the radicalization process and the forces driving violent extremist activity. It analyzes post-9/11 domestic jihadist terrorism, describes law enforcement and intelligence efforts to combat terrorism and the challenges associated with those efforts. It also outlines actions underway to build trust and partnership between community groups and government agencies and the tensions that may occur between law enforcement and engagement activities.

Analysis of Wind Power and Load Data at Multiple Time Scales (open access)

Analysis of Wind Power and Load Data at Multiple Time Scales

In this study we develop and apply new methods of data analysis for high resolution wind power and system load time series, to improve our understanding of how to characterize highly variable wind power output and the correlations between wind power and load. These methods are applied to wind and load data from the ERCOT region, and wind power output from the PJM and NYISO areas. We use a wavelet transform to apply mathematically well-defined operations of smoothing and differencing to the time series data. This approach produces a set of time series of the changes in wind power and load (or ?deltas?), over a range of times scales from a few seconds to approximately one hour. A number of statistical measures of these time series are calculated. We present sample distributions, and devise a method for fitting the empirical distribution shape in the tails. We also evaluate the degree of serial correlation, and linear correlation between wind and load. Our examination of the data shows clearly that the deltas do not follow a Gaussian shape; the distribution is exponential near the center and appears to follow a power law for larger fluctuations. Gaussian distributions are frequently used in modeling …

Automatic Fault Characterization via Abnormality-Enhanced Classification (open access)

Automatic Fault Characterization via Abnormality-Enhanced Classification

Enterprise and high-performance computing systems are growing extremely large and complex, employing hundreds to hundreds of thousands of processors and software/hardware stacks built by many people across many organizations. As the growing scale of these machines increases the frequency of faults, system complexity makes these faults difficult to detect and to diagnose. Current system management techniques, which focus primarily on efficient data access and query mechanisms, require system administrators to examine the behavior of various system services manually. Growing system complexity is making this manual process unmanageable: administrators require more effective management tools that can detect faults and help to identify their root causes. System administrators need timely notification when a fault is manifested that includes the type of fault, the time period in which it occurred and the processor on which it originated. Statistical modeling approaches can accurately characterize system behavior. However, the complex effects of system faults make these tools difficult to apply effectively. This paper investigates the application of classification and clustering algorithms to fault detection and characterization. We show experimentally that naively applying these methods achieves poor accuracy. Further, we design novel techniques that combine classification algorithms with information on the abnormality of application behavior to …

Aviation Security: Efforts to Validate TSA's Passenger Screening Behavior Detection Program Underway, but Opportunities Exist to Strengthen Validation and Address Operational Challenges

A letter report issued by the Government Accountability Office with an abstract that begins "To enhance aviation security, the Transportation Security Administration (TSA) began initial testing in October 2003 of its Screening of Passengers by Observation Techniques (SPOT) program. Behavior Detection Officers (BDO) carry out SPOT's mission to identify persons who pose a risk to aviation security by focusing on behavioral and appearance indicators. GAO was asked to review the SPOT program. GAO analyzed (1) the extent to which TSA validated the SPOT program before deployment, (2) implementation challenges, and (3) the extent to which TSA measures SPOT's effect on aviation security. GAO analyzed TSA documents, such as strategic plans and operating procedures; interviewed agency personnel and subject matter experts; and visited 15 SPOT airports, among other things. Although the results from these visits are not generalizable, they provided insights into SPOT operations."

Beyond the Standard Model: The Weak Scale, Neutrino Mass, and the Dark Sector

The goal of this proposal was to advance theoretical studies into questions of collider physics at the weak scale, models and signals of dark matter, and connections between neutrino mass and dark energy. The project was a significant success, with a number of developments well beyond what could have been anticipated at the outset. A total of 35 published papers and preprints were produced, with new ideas and signals for LHC physics and dark matter experiments, in particular. A number of new ideas have been found on the possible indirect signals of models of dark matter which relate to the INTEGRAL signal of astrophysical positron production, high energy positrons seen at PAMELA and Fermi, studies into anomalous gamma rays at Fermi, collider signatures of sneutrino dark matter, scenarios of Higgs physics arising in SUSY models, the implications of galaxy cluster surveys for photon-axion conversion models, previously unconsidered collider phenomenology in the form of 'lepton jets' and a very significant result for flavor physics in supersymmetric theories. Progress continues on all fronts, including development of models with dramatic implications for direct dark matter searches, dynamics of dark matter with various excited states, flavor physics, and consequences of modified missing energy signals …

CLOSE-OUT REPORT FOR HYS ELECTROLYZER COMPONENT DEVELOPMENT WORK AT SAVANNAH RIVER NATIONAL LABORATORY (open access)

CLOSE-OUT REPORT FOR HYS ELECTROLYZER COMPONENT DEVELOPMENT WORK AT SAVANNAH RIVER NATIONAL LABORATORY

The chemical stability, sulfur dioxide transport, ionic conductivity, and electrolyzer performance have been measured for several commercially available and experimental proton exchange membranes (PEMs) for use in a sulfur dioxide depolarized electrolyzer (SDE). The SDE's function is to produce hydrogen by using the Hybrid Sulfur (HyS) Process, a sulfur based electrochemical/thermochemical hybrid cycle. Membrane stability was evaluated using a screening process where each candidate PEM was heated at 80 C in 63.5 wt. % H{sub 2}SO{sub 4} for 24 hours. Following acid exposure, chemical stability for each membrane was evaluated by FTIR using the ATR sampling technique. Membrane SO{sub 2} transport was evaluated using a two-chamber permeation cell. SO{sub 2} was introduced into one chamber whereupon SO{sub 2} transported across the membrane into the other chamber and oxidized to H{sub 2}SO{sub 4} at an anode positioned immediately adjacent to the membrane. The resulting current was used to determine the SO{sub 2} flux and SO{sub 2} transport. Additionally, membrane electrode assemblies (MEAs) were prepared from candidate membranes to evaluate ionic conductivity and selectivity (ionic conductivity vs. SO{sub 2} transport) which can serve as a tool for selecting membranes. MEAs were also performance tested in a HyS electrolyzer measuring current density versus …
