Department of Homeland Security: Risk Assessment and Enhanced Oversight Needed to Manage Reliance on Contractors

Description: Testimony issued by the Government Accountability Office with an abstract that begins "In fiscal year 2005, the Department of Homeland Security (DHS) obligated $1.2 billion to procure four types of professional and management support services. While contracting for such services can help DHS meet its needs, using contractors to provide services that closely support inherently governmental functions increases the risk of government decisions being influenced by, rather than independent from, con… more

Digital Television Transition: Preliminary Information on Progress of the DTV Transition

Description: Testimony issued by the Government Accountability Office with an abstract that begins "On February 17, 2009, federal law requires all full-power television stations in the United States to cease analog broadcasting, enabling the government to reclaim valuable spectrum that the broadcasters currently use for analog broadcasts. This change, often referred to as the digital television (DTV) transition, requires action by broadcasters and consumers to ensure broadcast television signals are still a… more

Water, law, science

Description: In a world with water resources severely impacted bytechnology, science must actively contribute to water law. To this end,this paper is an earth scientist s attempt to comprehend essentialelements of water law, and to examine their connections to science.Science and law share a common logical framework of starting with apriori prescribed tenets, and drawing consistent inferences. In science,observationally established physical laws constitute the tenets, while inlaw, they stem from social valu… more

Power System Extreme Event Detection: The VulnerabilityFrontier

Description: In this work we apply graph theoretic tools to provide aclose bound on a frontier relating the number of line outages in a gridto the power disrupted by the outages. This frontier describes theboundary of a space relating the possible severity of a disturbance interms of power disruption, from zero to some maximum on the boundary, tothe number line outages involved in the event. We present the usefulnessof this analysis with a complete analysis of a 30 bus system, and presentresults for larger … more

Collaborative Research: Dynamics of Electrostatic Solitary Waves and their Effects on Current Layers

Description: The contents of this final report require explanation, as the report cannot be written in a manner consistent with the usual guidelines for a final scientific technical report. The original PI on this grant was Professor Paul Kintner who passed away November 16, 2010. I, Charles E. Seyler, was asked by the Director of the School of Electrical and Computer Engineering to take over the grant last May and try to fulfill its obligations to the PIs at the lead institution (UNH). I have worked with P… more

Analysis of Slice Transverse Emittance Evolution ina Photocathode RF Gun

Description: The slice transverse emittance of an electron beam is of critical significance for an x-ray FEL. In a photocathode RF gun, the slice transverse emittance is not only determined by the emission process, but also influenced strongly by the non-linear space charge effect. In this paper, we study the slice transverse emittance evolution in a photocathode RF gun using a simple model that includes effects of RF acceleration, focusing, and space charge force. The results are compared with IMPACT-T spa… more

Phase Stability under Irradiation of Precipitates and Solid Solutions in Model ALloys and in ODS Alloys Relevant for Gen IV

Description: The overall objective of this program is to investigate the irradiation-altered phase stability of oxide precipitates in ODS steels and of model alloy solid solutions of associated systems. This information can be used to determine whether the favorable mechanical propertiies of these steels are maintained under irradiation, thus addressing one of the main materials research issues for this class of steels as identified by the GenIV working groups. The research program will also create fundamen… more

Cosmic Ray Electron Science with GLAST

Description: Cosmic ray electrons at high energy carry information about their sources, their diffusion in local magnetic fields and their interactions with the photon fields through which they travel. The spectrum of the particles is affected by inverse Compton losses and synchrotron losses, the rates of which are proportional to the square of the particle's energy making the spectra very steep. However, GLAST will be able to make unique and very high statistics measurements of electrons from {approx}20 to… more

Evaluation of Oil-Industry Stimulation Practices for Engineered Geothermal Systems

Description: Geothermal energy extraction is typically achieved by use of long open-hole intervals in an attempt to connect the well with the greatest possible rock mass. This presents a problem for the development of Enhanced (Engineered) Geothermal Systems (EGS), owing to the challenge of obtaining uniform stimulation throughout the open-hole interval. Fluids are often injected in only a fraction of that interval, reducing heat transfer efficiency and increasing energy cost. Pinnacle Technologies, Inc. an… more
