Senate Policy Committees (open access)

Senate Policy Committees

The two policy committees are different in structure and operation, a contrast that appears to be rooted in different leadership styles within the two party organizations. Republican leadership has traditionally been shared among Senators other than the party floor leader; customarily, the Democratic leadership positions of party floor leader, chair of the Democratic Policy Committee, and chair of the Democratic Conference have been posts held by the same person. This report covers the history of the two Senate policy committees and explains their structure, operation, and functions.

A Quantitative Comparison of Numerical Methods for the Compressible Euler Equations: Fifth-order WENO and Piecewise-Linear Godunov (open access)

A Quantitative Comparison of Numerical Methods for the Compressible Euler Equations: Fifth-order WENO and Piecewise-Linear Godunov

A numerical study is undertaken comparing a fifth-order version of the weighted essentially non-oscillatory numerical (WENO5) method to a modern piecewise-linear, second-order, version of Godunov's (PLMDE) method for the compressible Euler Equations. A series of one-dimensional test problems are examined beginning with classical linear problems and ending with complex shock interactions. The problems considered are: (1) linear advection of a Gaussian pulse in density, (2) Sod's shock tube problem, (3) the ''peak'' shock tube problem, (4) a version of the Shu and Osher shock entropy wave interaction and (5) the Woodward and Colella interacting shock wave problem. For each problem and method, run times, density error norms and convergence rates are reported for each method as produced from a common code test-bed. The linear problem exhibits the advertised convergence rate for both methods as well as the expected large disparity in overall error levels; WENO5 has the smaller errors and an enormous advantage in overall efficiency (in accuracy per unit CPU time). For the nonlinear problems with discontinuities, however, we generally see both first-order self-convergence of error as compared to an exact solution, or when an analytic solution is not available, a converged solution generated on an extremely fine grid. …

Estimated Entrainment of Dungeness Crab During Maintenance Dredging of the Mouth of the Columbia River, Summer 2002 (open access)

Estimated Entrainment of Dungeness Crab During Maintenance Dredging of the Mouth of the Columbia River, Summer 2002

To address concerns about crab entrainment during maintenance dredging at the Mouth of the Columbia River, direct measurements of crab entrainment rates were conducted during the summer of 2002 from River Mile 3 to River Mile+3. The entrainment rate for all age classes over all sampling in the MCR was 0.0603 crabs per cy. The sex ratio of the older crabs entrained in the MCR was significantly skewed to the females. A modified DIM was used to calculate the entrainment (E), Adult Equivalent Loss (AEL) at Age 2+ and Age 3+ and the Loss to the Fishery (LF) for the dredged volumes accomplished in 2002 and for the five-year average dredged volumes (both for the Essayons and the contractor dredges). For both sets of projections, the coefficients of variation on the E, AEL, and LF were all under 5%. For the MCR total dredged volume (4,600,378 cy) in the summer of 2002, the estimated AEL at age 2+ was 180,416 crabs with 95% confidence limits from 163,549 to 197,283 crabs. The AEL at age 3+ estimated for the summer 2002 in the MCR was 81,187 with 95% confidence limits from 73,597 to 88,777 crabs. The projected LF for summer 2002 …

Assessment of Physical Properties of Transuranic Waste in Hanford Single-Shell Tanks (open access)

Assessment of Physical Properties of Transuranic Waste in Hanford Single-Shell Tanks

CH2M HILL Hanford Group, Inc. (CH2M HILL) is in the process of identifying and developing supplemental process technologies to accelerate the tank waste cleanup mission. One technology targets disposal of Hanford transuranic (TRU) process wastes stored in single-shell tanks (SSTs). Ten Hanford SSTs are candidates for designation as contact-handled TRU waste type: the B-200 series tanks (241-B-201, -B-202, -B-203, and -B-204), the T-200 series tanks (241-T-201, -T-202, -T-203, and -T-204), and Tanks 241-T-110 and T-111. Current plans identify a process in which these wastes are retrieved from the tanks, either dry or with a recycled liquid stream to help mobilize the waste in the tank and through transfer lines and vessels, dewatered to remove excess liquid, and transferred to waste packages in a form suitable for disposal. CH2M HILL seeks to procure a process for dewatering, handling, and packaging the contact-handled TRU waste after it is retrieved. An understanding of waste physical properties is needed to support design of the SST TRU handling and packaging system and to produce suitable physical simulants to test such a process. Pacific Northwest National Laboratory (PNNL) has been tasked with developing these waste simulants. This report summarizes PNNL's assessment of available waste physical property …

Social Security Notch Issue: A Summary (open access)

Social Security Notch Issue: A Summary

This report discusses recent attempts at legislative action regarding changes to the computation of benefits under Social Security Amendments of 1977 (P.L. 95-216), which directly affected retirees born in the 5- to 15-year period after 1916. These persons fall in the "notch" between previous Social Security legislation and those affected by the amendments.
