ARM CLASIC ER2 CRS/EDOP (open access)

ARM CLASIC ER2 CRS/EDOP

Data was taken with the NASA ER-2 aircraft with the Cloud Radar System and other instruments in conjunction with the DOE ARM CLASIC field campaign. The flights were near the SGP site in north Central Oklahoma and targeted small developing convection. The CRS is a 94 GHz nadir pointing Doppler radar. Also on board the ER-2 was the Cloud Physics Lidar (CPL). Seven science flights were conducted but the weather conditions did not cooperate in that there was neither developing convection, or there was heavy rain.

The Army Corps of Engineers' Nationwide Permits Program: Issues and Regulatory Developments (open access)

The Army Corps of Engineers' Nationwide Permits Program: Issues and Regulatory Developments

Congressional interest in wetlands permit regulatory programs has been evident in the past in oversight hearings and in connection with bills to fund the Corps' regulatory programs. For some time, there has been a stalemate over legislation that would revise wetlands regulatory law and that could, if enacted, modify the nationwide permit program. During this time, no consensus has emerged on whether or how to reform overall wetlands policy legislatively. Recently, Obama Administration initiatives and actions intended to restrict harmful effects of surface coal mining activities in Appalachia have drawn congressional attention and criticism that is likely to continue in the 112th Congress and that could include oversight of the Corps' regulatory program generally.

Arsenic Water Technology Partnership Final Technical Report (open access)

Arsenic Water Technology Partnership Final Technical Report

Congress created the Arsenic Water Technology Partnership (AWTP) in 2002 to develop and provide solutions for the cost-effective removal of arsenic from drinking water. The AWTP was funded by four congressional appropriations (FY03-FY06) to evaluate and develop new technologies that could significantly reduce compliance costs associated with the new 0.010 mg/L maximum contaminant level (MCL) for arsenic in drinking water. Initially focused on arsenic research, in FY06 the AWTP was expanded to include desalination research upon recognition that the research challenges were similar. The funding for the research and subsequent transfer of technology was made available by Congress through the Department of Energy (DOE). The AWTP was a collaborative effort between DOE’s Sandia National Laboratories (Sandia), Water Research Foundation (WaterRF, formerly Awwa Research Foundation) and WERC: A Consortium for Environmental Education and Technology Development based at New Mexico State University (WERC). Key features of the AWTP included technology development, technology implementation/testing and technology transfer. Each of the partners evaluated and oversaw development of new arsenic and desalination treatment technologies, and the technology transfer program ensured that successful technologies were transferred to the water supply community. Through the use of an arsenic treatment cost model, training sessions and a web site, …

Assessment of neutron skyshine near unmodified Accumulator Debuncher storage rings under Mu2e operational conditions (open access)

Assessment of neutron skyshine near unmodified Accumulator Debuncher storage rings under Mu2e operational conditions

Preliminary plans for providing the proton beam needed by the proposed Mu2e experiment at Fermilab will require the transport of 8 GeV protons to the Accumulator/Debuncher where they be processed into an intensity and time structure useful for the experiment. The intensities involved are far greater that those encountered with antiprotons of the same kinetic energy in the same beam enclosures under Tevatron Collider operational conditions, the operating parameters for which the physical facilities of the Antiproton Source were designed. This note explores some important ramifications of the proposed operation for radiation safety and demonstrates the need for extensive modifications of significant portions of the shielding of the Accumulator Debuncher storage rings; notably that underneath the AP Service Buildings AP10, AP30, and AP50. While existing shielding is adequate for the current operating mode of the Accumulator/Debuncher as part of the Antiproton Source used in the Tevatron Collider program, without significant modifications of the shielding configuration in the Accumulator/Debuncher region and/or beam loss control systems far more effective than seen in most applications at Fermilab, the proposed operational mode for Mu2e is not viable for the following reasons: 1. Due to skyshine alone, under normal operational conditions large areas of the …

Atomic magnetometer for human magnetoencephalograpy. (open access)

Atomic magnetometer for human magnetoencephalograpy.

We have developed a high sensitivity (<5 fTesla/{radical}Hz), fiber-optically coupled magnetometer to detect magnetic fields produced by the human brain. This is the first demonstration of a noncryogenic sensor that could replace cryogenic superconducting quantum interference device (SQUID) magnetometers in magnetoencephalography (MEG) and is an important advance in realizing cost-effective MEG. Within the sensor, a rubidium vapor is optically pumped with 795 laser light while field-induced optical rotations are measured with 780 nm laser light. Both beams share a single optical axis to maximize simplicity and compactness. In collaboration with neuroscientists at The Mind Research Network in Albuquerque, NM, the evoked responses resulting from median nerve and auditory stimulation were recorded with the atomic magnetometer and a commercial SQUID-based MEG system with signals comparing favorably. Multi-sensor operation has been demonstrated with two AMs placed on opposite sides of the head. Straightforward miniaturization would enable high-density sensor arrays for whole-head magnetoencephalography.

Attributes of the Federal Energy Management Program's Federal Site Building Characteristics Database (open access)

Attributes of the Federal Energy Management Program's Federal Site Building Characteristics Database

Typically, the Federal building stock is referred to as a group of about one-half million buildings throughout the United States. Additional information beyond this level is generally limited to distribution of that total by agency and maybe distribution of the total by state. However, additional characterization of the Federal building stock is required as the Federal sector seeks ways to implement efficiency projects to reduce energy and water use intensity as mandated by legislation and Executive Order. Using a Federal facility database that was assembled for use in a geographic information system tool, additional characterization of the Federal building stock is provided including information regarding the geographical distribution of sites, building counts and percentage of total by agency, distribution of sites and building totals by agency, distribution of building count and floor space by Federal building type classification by agency, and rank ordering of sites, buildings, and floor space by state. A case study is provided regarding how the building stock has changed for the Department of Energy from 2000 through 2008.

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 …

Automation Enhancement of Multilayer Laue Lenses (open access)

Automation Enhancement of Multilayer Laue Lenses

X-ray optics fabrication at Brookhaven National Laboratory has been facilitated by a new, state of the art magnetron sputtering physical deposition system. With its nine magnetron sputtering cathodes and substrate carrier that moves on a linear rail via a UHV brushless linear servo motor, the system is capable of accurately depositing the many thousands of layers necessary for multilayer Laue lenses. I have engineered a versatile and automated control program from scratch for the base system and many subsystems. Its main features include a custom scripting language, a fully customizable graphical user interface, wireless and remote control, and a terminal-based interface. This control system has already been successfully used in the creation of many types of x-ray optics, including several thousand layer multilayer Laue lenses.Before reaching the point at which a deposition can be run, stencil-like masks for the sputtering cathodes must be created to ensure the proper distribution of sputtered atoms. Quality of multilayer Laue lenses can also be difficult to measure, given the size of the thin film layers. I employ my knowledge of software and algorithms to further ease these previously painstaking processes with custom programs. Additionally, I will give an overview of an x-ray optic simulator …

B-2 Bomber: Review of the Air Force's Decision to Change Extremely High Frequency Satellite Communications Antennas (open access)

B-2 Bomber: Review of the Air Force's Decision to Change Extremely High Frequency Satellite Communications Antennas

Correspondence issued by the Government Accountability Office with an abstract that begins "The B-2 bomber is a low-observable, long-range strike aircraft capable of entering heavily defended areas to deliver both conventional and nuclear weapons. The B-2 currently uses an ultra high frequency (UHF) satellite communications system, but because of aging military satellites, the Air Force determined a new communications system was needed. As a result, the Air Force began an incremental acquisition approach for replacing the B-2's existing UHF satellite communications system with an extremely high frequency (EHF) communications capability. The first increment, which is expected to begin production in late fiscal year 2011, is designed to upgrade computer system speed and storage capacity. The second increment is expected to provide secure, survivable strategic communications connectivity, thus allowing B-2 pilots to receive emergency action messages during strategic operations--an EHF capability that U.S. Strategic Command has stated it needs by fiscal year 2016. The third increment is intended to enable the EHF system to connect with the Global Information Grid. The focus of our review was the second increment, which is scheduled to enter the engineering and manufacturing development (EMD) phase in early fiscal year 20131 and has an estimated total …

Baseball in the Digital Age: The Role of Online and Mobile Content in Major League Baseball's Media Product Portfolio

This case study evaluated Major League Baseball's (MLB) media product portfolio to identify how broadcast revenues have evolved over the past decade. This research looked back across baseball's long, dysfunctional history with broadcasters in order to recognize the significance of its ambitious use of online content. While MLB had failed to fully utilize the potential of broadcasting, the league's aggressive online strategy through its Advanced Media (MLBAM) division made it the industry leader in broadcasting live streaming sports video. MLBAM expanded its online streaming video to mobile phones and iPad, further expanding the distribution of its content. This research compared MLBAM revenue to traditional broadcast revenue while analyzing the online division's role in promoting the MLB brand. This case study concluded that while MLBAM had made a number of groundbreaking developments, the league could still improve its use of embedded, shared video clips, archived footage and international marketing in order to further extend the brand equity of the MLB, its thirty individual brands and its media product portfolio.

Battery Test Manual For Plug-In Hybrid Electric Vehicles (open access)

Battery Test Manual For Plug-In Hybrid Electric Vehicles

This battery test procedure manual was prepared for the United States Department of Energy (DOE), Office of Energy Efficiency and Renewable Energy (EERE), Vehicle Technologies Program. It is based on technical targets established for energy storage development projects aimed at meeting system level DOE goals for Plug-in Hybrid Electric Vehicles (PHEV). The specific procedures defined in this manual support the performance and life characterization of advanced battery devices under development for PHEV’s. However, it does share some methods described in the previously published battery test manual for power-assist hybrid electric vehicles. Due to the complexity of some of the procedures and supporting analysis, a revision including some modifications and clarifications of these procedures is expected. As in previous battery and capacitor test manuals, this version of the manual defines testing methods for full-size battery systems, along with provisions for scaling these tests for modules, cells or other subscale level devices.
