Airline Deregulation: Reregulating the Airline Industry Would Likely Reverse Consumer Benefits and Not Save Airline Pensions
A letter report issued by the Government Accountability Office with an abstract that begins "The Airline Deregulation Act of 1978 phased out the government's control over fares and service and allowed market forces to determine the price and level of domestic airline service in the United States. The intent was to increase competition and thereby lead to lower fares and improved service. In 2005, GAO reported on the tenuous finances of some airlines that have led to bankruptcy and pension terminations, in particular among those airlines that predated deregulation (referred to as legacy airlines). The House Report accompanying the 2006 Department of Transportation (DOT) Appropriation Act expressed concern about airline pension defaults and charged GAO with analyzing the impact of reregulating the airline industry on reducing potential pension defaults by airlines. GAO subsequently agreed to address the pension issue within a broad assessment of the airline industry since deregulation. Specifically, GAO is reporting on, among other things, (1) broad airline industry changes since deregulation, (2) fare and service changes since deregulation, and (3) whether there is evidence that reregulation of entry and fares would benefit consumers or the airline industry, or save airline pensions. DOT agreed with the conclusions in …

Alaska Native Corporations: Increased Use of Special 8(a) Provisions Calls for Tailored Oversight
Testimony issued by the Government Accountability Office with an abstract that begins "Alaska Native corporations (ANC) were created to settle land claims with Alaska Natives and foster economic development. In 1986, legislation passed that allowed ANCs to participate in the Small Business Administration's (SBA) 8(a) program. Since then, Congress has extended special procurement advantages to 8(a) ANC firms, such as the ability to receive sole-source contracts for any dollar amount and to own multiple subsidiaries in the 8(a) program. We were asked to testify on an earlier report where we identified (1) trends in the government's 8(a) contracting with ANC firms, (2) the reasons agencies have awarded 8(a) solesource contracts to ANC firms and the facts and circumstances behind some of these contracts, and (3) how ANCs are using the 8(a) program. GAO also evaluated SBA's oversight of 8(a) ANC firms. GAO made recommendations aimed at improving SBA's oversight of 8(a) ANC contracting activity and ensuring that procuring agencies properly oversee 8(a) contracts they award to ANC firms. The procuring agencies generally agreed with our recommendation. SBA expressed concern with aspects of the report and disagreed with several of our recommendations. We believe implementation of our recommendations would provide better …

ALE3D Simulation of Heating and Violence in a Fast Cookoff Experiment with LX-10
We performed a computational and experimental analysis of fast cookoff of LX-10 (94.7% HMX, 5.3% Viton A) confined in a 2 kbar steel tube with reinforced end caps. A Scaled-Thermal-Explosion-eXperiment (STEX) was completed in which three radiant heaters were used to heat the vessel until ignition, resulting in a moderately violent explosion after 20.4 minutes. Thermocouple measurements showed tube temperatures as high as 340 C at ignition and LX-10 surface temperatures as high as 279 C, which is near the melting point of HMX. Three micro-power radar systems were used to measure mean fragment velocities of 840 m/s. Photonics Doppler Velocimeters (PDVs) showed a rapid acceleration of fragments over 80 {micro}s. A one-dimensional ALE3D cookoff model at the vessel midplane was used to simulate the heating, thermal expansion, LX-10 decomposition composition, and closing of the gap between the HE (High Explosive) and vessel wall. Although the ALE3D simulation terminated before ignition, the model provided a good representation of heat transfer through the case and across the dynamic gap to the explosive.

ALE3D Simulations of Gap Closure and Surface Ignition for Cookoff Modeling
We are developing ALE3D models to describe the thermal, chemical and mechanical behavior during the heating, ignition and explosive phases of various cookoff phenomena. The candidate models and numerical strategies are being evaluated using benchmark cookoff experiments. ALE3D is a three-dimensional computer code capable of solving the model equations in a coupled fashion through all the phases of the cookoff in a single calculation. For the cookoff experiments, we are interested in representing behavior on widely varying timescales. We have used an implicit hydrodynamics option during the heating phase and an explicit solution method during the explosive phase. To complicate the modeling problem, high heat fluxes cause rapid temperature increases in boundary layers and lead to the formation of gaps between energetic and structural materials and ignition on surfaces. The initially solid energetic and structural materials react to produce gases, which fill the gaps. These materials can also melt and flow. Since an implicit solution method is used, simple no-strength materials models can no longer be used for liquids and gases. In this paper, we discuss and demonstrate choices of materials models for solid/liquid/gas mixtures to be used in conjunction with the implicit solution method. In addition, results are given …

Algebraic Sub-Structuring for Electromagnetic Applications
Algebraic sub-structuring refers to the process of applying matrix reordering and partitioning algorithms to divide a large sparse matrix into smaller submatrices from which a subset of spectral components are extracted and combined to form approximate solutions to the original problem. In this paper, they show that algebraic sub-structuring can be effectively used to solve generalized eigenvalue problems arising from the finite element analysis of an accelerator structure.
