Federal Protective Service: Preliminary Results on Efforts to Assess Facility Risks and Oversee Contract Guards

Testimony issued by the Government Accountability Office with an abstract that begins "GAO’s preliminary results indicate that the Department of Homeland Security’s (DHS) Federal Protective Service (FPS) is not assessing risks at federal facilities in a manner consistent with standards such as the National Infrastructure Protection Plan’s (NIPP) risk management framework, as FPS originally planned. Instead of conducting risk assessments, since September 2011, FPS’s inspectors have collected information, such as the location, purpose, agency contacts, and current countermeasures (e.g., perimeter security, access controls, and closed-circuit television systems). This information notwithstanding, FPS has a backlog of federal facilities that have not been ssessed for several years. According to FPS’s data, more than 5,000 facilities were to be assessed in fiscal years 2010 through 2012. However, GAO was not able to determine the extent of FPS’s facility security assessment (FSA) backlog because the data were unreliable. Multiple agencies have expended resources to conduct risk assessments, even though they also already pay FPS for this service."

Final Technical Report - Advanced Optical Sensors to Minimize Energy Consumption in Polymer Extrusion Processes (open access)

Final Technical Report - Advanced Optical Sensors to Minimize Energy Consumption in Polymer Extrusion Processes

Project Objective: The objectives of this study are to develop an accurate and stable on-line sensor system to monitor color and composition on-line in polymer melts, to develop a scheme for using the output to control extruders to eliminate the energy, material and operational costs of off-specification product, and to combine or eliminate some extrusion processes. Background: Polymer extrusion processes are difficult to control because the quality achieved in the final product is complexly affected by the properties of the extruder screw, speed of extrusion, temperature, polymer composition, strength and dispersion properties of additives, and feeder system properties. Extruder systems are engineered to be highly reproducible so that when the correct settings to produce a particular product are found, that product can be reliably produced time after time. However market conditions often require changes in the final product, different products or grades may be processed in the same equipment, and feed materials vary from lot to lot. All of these changes require empirical adjustment of extruder settings to produce a product meeting specifications. Optical sensor systems that can continuously monitor the composition and color of the extruded polymer could detect process upsets, drift, blending oscillations, and changes in dispersion of …

Student and Exchange Visitor Program: DHS Needs to Take Actions to Strengthen Monitoring of Schools

Testimony issued by the Government Accountability Office with an abstract that begins "In summary, we reported that ICE does not have a process to identify and assess risks posed by schools in SEVP. Specifically, SEVP (1) does not evaluate program data on prior and suspected instances of school fraud and noncompliance, and (2) does not obtain and assess information from CTCEU and ICE field office school investigations and outreach events. Moreover, weaknesses in ICE’s monitoring and oversight of SEVP-certified schools contribute to security and fraud vulnerabilities. For example, ICE has not consistently implemented internal control procedures for SEVP in the initial verification of evidence submitted in lieu of accreditation. In addition, ICE has not consistently followed the standard operating procedures that govern the communication and coordination process among SEVP, CTCEU, and ICE field offices. We recommended that ICE, among other things, identify and assess risks posed by schools in SEVP. Specifically, SEVP (1) does not evaluate program data on prior and suspected instances of school fraud and noncompliance, and (2) does not obtain and assess information from CTCEU and ICE field office school investigations and outreach events.

Telecommunications: Exposure and Testing Requirements for Mobile Phones Should Be Reassessed

A letter report issued by the Government Accountability Office with an abstract that begins "Scientific research to date has not demonstrated adverse human health effects of exposure to radio-frequency (RF) energy from mobile phone use, but research is ongoing that may increase understanding of any possible effects. In addition, officials from the Food and Drug Administration (FDA) and the National Institutes of Health (NIH) as well as experts GAO interviewed have reached similar conclusions about the scientific research. Ongoing research examining the health effects of RF energy exposure is funded and supported by federal agencies, international organizations, and the mobile phone industry. NIH is the only federal agency GAO interviewed directly funding studies in this area, but other agencies support research under way by collaborating with NIH or other organizations to conduct studies and identify areas for additional research."

Bunch Profiling Using a Rotating Mask (open access)

Bunch Profiling Using a Rotating Mask

The current method for measuring profiles of proton bunches in accelerators is severely lacking. One must dedicate a great deal of time and expensive equipment to achieve meaningful results. A new method to complete this task uses a rotating mask with slots of three different orientations to collect this data. By scanning over the beam in three different directions, a complete profile for each bunch is built in just seconds, compared to the hours necessary for the previous method. This design was successfully tested using synchrotron radiation emitted by SPEAR3. The profile of the beam was measured in each of the three desired directions. Due to scheduled beam maintenance, only one set of data was completed and more are necessary to solve any remaining issues. The data collected was processed and all of the RMS sizes along the major and minor axes, as well as the tilt of the beam ellipse were measured.

Characterizing the Nanoscale Layers of Tomorrow___s Electronics An Application of Fourier Analysis

Thin film applications are of great interest to the semiconductor industry due to the important role they play in cutting edge technology such as thin film solar cells. X-Ray Reflectivity (XRR) characterizes thin films in a non-destructive and efficient manner yet complications exist in extracting these characteristics from raw XRR data. This study developed and tested two different algorithms to extract quantity of layers and thickness information on the nanometer scale from XRR data. It was concluded that an algorithm involving a local averaging technique revealed this information clearly in Fourier space.

Electron Beam Polarization Measurement Using Touschek Lifetime Technique (open access)

Electron Beam Polarization Measurement Using Touschek Lifetime Technique

Electron beam loss due to intra-beam scattering, the Touschek effect, in a storage ring depends on the electron beam polarization. The polarization of an electron beam can be determined from the difference in the Touschek lifetime compared with an unpolarized beam. In this paper, we report on a systematic experimental procedure recently developed at Duke FEL laboratory to study the radiative polarization of a stored electron beam. Using this technique, we have successfully observed the radiative polarization build-up of an electron beam in the Duke storage ring, and determined the equilibrium degree of polarization and the time constant of the polarization build-up process.

Femtosecond Synchronization of Laser Systems for the LCLS (open access)

Femtosecond Synchronization of Laser Systems for the LCLS

The scientific potential of femtosecond x-ray pulses at linac-driven free-electron lasers such as the Linac Coherent Light Source is tremendous. Time-resolved pump-probe experiments require a measure of the relative arrival time of each x-ray pulse with respect to the experimental pump laser. An optical timing system based on stabilized fiber links has been developed for the LCLS to provide this synchronization. Preliminary results show synchronization of the installed stabilized links at the sub-20-femtosecond level. We present details of the implementation at LCLS and potential for future development.

Home Energy Assistance for Low-Income Occupants of Manufactured Homes

Correspondence issued by the Government Accountability Office with an abstract that begins "In 2005, the most recent year for which complete data were available, occupants of older manufactured homes paid over twice as much on average per square foot for energy---$1.75 per square foot as compared with $0.87---as was paid by occupants of detached homes. Annual energy expenditures for older manufactured homes--about 906 square feet on average--were about $1,369, compared with detached homes--about 2,919 square feet on average--were about $2,060. Energy expenditures--both per square foot and annually--varied significantly by region reflecting regional differences in the types and costs of fuels commonly used to heat and cool homes, income levels, and climate, among other things. In 2005, LIHEAP provided more assistance on a per square foot basis--about $0.33 per square foot--to occupants of older manufactured homes than to those of detached homes--about $0.20 per square foot. However, this assistance covers slightly less of the annual energy expenditures of occupants of older manufactured homes than occupants of detached homes--15 and 17 percent, respectively. Based on our analysis of EIA's RECS data, we estimate that about 3 percent of LIHEAP funds--about $57 million--spent in 2005 were used to assist occupants of older manufactured …

An Improved Technique for Increasing the Accuracy of Photometrically Determined Redshifts for ___Blended___ Galaxies (open access)

An Improved Technique for Increasing the Accuracy of Photometrically Determined Redshifts for ___Blended___ Galaxies

The redshift of a galaxy can be determined by one of two methods; photometric or spectroscopic. Photometric is a term for any redshift determination made using the magnitudes of light in different filters. Spectroscopic redshifts are determined by measuring the absorption spectra of the object then determining the difference in wavelength between the 'standard' absorption lines and the measured ones, making it the most accurate of the two methods. The data for this research was collected from SDSS DR8 and then separated into blended and non-blended galaxy sets; the definition of 'blended' is discussed in the Introduction section. The current SDSS photometric redshift determination method does not discriminate between blended and non-blended data when it determines the photometric redshift of a given galaxy. The focus of this research was to utilize machine learning techniques to determine if a considerably more accurate photometric redshift determination method could be found, for the case of the blended and non-blended data being treated separately. The results show a reduction of 0.00496 in the RMS error of photometric redshift determinations for blended galaxies and a more significant reduction of 0.00827 for non-blended galaxies, illustrated in Table 2.

Japan's Possible Entry Into the Trans-Pacific Partnership and Its Implications

This report discusses the effects of the possible entry of Japan to the Trans-Pacific Partnership (TPP) negotiations. The TPP issue presents both risks and opportunities for the United States and Japan. On the one hand, it could reinvigorate an economic relationship that has remained steady but stagnant, by forcing the two countries to address long-standing, difficult issues, and allowing them to raise their relationship to a higher level. On the other hand, failure to do so could indicate that the underlying problems are too fundamental to overcome and could set back the relationship.

Magnet Lattice Design for the Transmission of Power Using Particle Beams (open access)

Magnet Lattice Design for the Transmission of Power Using Particle Beams

As the amount of electricity generated by renewable energy sources continues to increase, the current method of power transmission will not serve as an adequate method for transmitting power over very long distances. A new method for transmitting power is proposed using particle beams in a storage ring. Particle beams offer an incredibly energy efficient alternative to transmission lines in transmitting power over very long distances. A thorough investigation of the magnet lattice design for this storage ring is presented. The design demonstrates the ability to design a ring with stable orbits over a 381.733 km circumference. Double bend achromats and FODO cells are implemented to achieve appropriate {beta} functions and dispersion functions for 9-11 GeV electron beams.

Measuring Cluster Relaxedness (open access)

Measuring Cluster Relaxedness

When is a dark matter halo 'relaxed'? In our efforts to understand the structure of the universe, dark matter simulations have provided essential grounds for theoretical predictions. These simulations provide a wealth of ways of parameterizing and measuring the features of astronomical objects. It is these measurements on which we base comparisons of our world and our attempts to re-create it. One of the essential questions dark matter simulations help address is how dark matter halos evolve. How does one characterize different states of that evolution? The focus of this project is identifying cluster relaxedness and how it relates to the internal structure of the halo. A dark matter simulation consists of an N-body simulation which takes an initial set of positions and velocities of the dark matter particles and evolves them under the influence of gravity [6]. Though scientists have so far not been able to detect dark matter particles, the information from these simulations is still valuable especially given the relationship between dark matter halos and galaxy clusters. Galaxies sit within dark matter halos and recent evidence points to filaments of dark matter forming the framework on which galaxy clusters grow [7]. A dark matter halo is a …

Modular control of fusion power heating applications (open access)

Modular control of fusion power heating applications

This work is motivated by the growing demand for auxiliary heating on small and large machines worldwide. Numerous present and planned RF experiments (EBW, Lower Hybrid, ICRF, and ECH) are increasingly complex systems. The operational challenges are indicative of a need for components of real-time control that can be implemented with a moderate amount of effort in a time- and cost-effective fashion. Such a system will improve experimental efficiency, enhance experimental quality, and expedite technological advancements. The modular architecture of this control-suite serves multiple purposes. It facilitates construction on various scales from single to multiple controller systems. It enables expandability of control from basic to complex via the addition of modules with varying functionalities. It simplifies the control implementation process by reducing layers of software and electronic development. While conceived with fusion applications in mind, this suite has the potential to serve a broad range of scientific and industrial applications. During the Phase-I research effort we established the overall feasibility of this modular control-suite concept. We developed the fundamental modules needed to implement open-loop active-control and demonstrated their use on a microwave power deposition experiment.
