Acoustic Propagation in a Water-Filled Cylindrical Pipe

Description: This study was concerned with the physics of the propagation of a tone burst of high frequency sound in a steel water-filled pipe. The choice of the pulse was rather arbitrary, so that this work in no way can be considered as recommending a particular pulse form. However, the MATLAB computer codes developed in this study are general enough to carry out studies of pulses of various forms. Also, it should be pointed out that the codes as written are quite time consuming. A computation of the comp… more

Investigate Methods to Decrease Compilation Time-AX-Program Code Group Computer Science R& D Project

Description: Large simulation codes can take on the order of hours to compile from scratch. In Kull, which uses generic programming techniques, a significant portion of the time is spent generating and compiling template instantiations. I would like to investigate methods that would decrease the overall compilation time for large codes. These would be methods which could then be applied, hopefully, as standard practice to any large code. Success is measured by the overall decrease in wall clock time a devel… more

Theoretical Aerodynamic Analyses of Six Airfoils for Use on Small Wind Turbines: July 11, 2002--October 31, 2002

Description: Theoretical analyses of six airfoils--the E 387, FX 63-137, S822, S834, SD2030, and SH3055--have been performed for Reynolds numbers from 0.10 x 106 to 1.00 x 106 using the Eppler Airfoil Design and Analysis Code and the XFOIL code. The results from both codes exhibit the typical Reynolds number and roughness effects. Comparisons of the results from the two codes generally show good agreement, particularly for Reynolds numbers greater than 0.10 x 106. The maximum lift coefficient predicted by t… more

Estimating the Deformability and Strength of Rock Masses - In-Situ Tests, and Related Procedures

Description: This report was prepared for presentation at the STRATCOM Advanced Concept Technology Demonstration (ACTD) meeting held in Albuquerque, New Mexico, May 21, 2003. It discusses the methods that can be used to estimate the mechanical properties of rock masses, such as deformability and strength. Special emphasis is put on the fact that rock mass properties are subject to an effect of scale, i.e. the properties measured on laboratory-scale samples are not representative of in-situ properties becaus… more

A Compendium of Transfer Factors for Agricultural and Animal Products

Description: Transfer factors are used in radiological risk assessments to estimate the amount of radioactivity that could be present in a food crop or organism based on the calculated concentration in the source medium (i.e., soil or animal feed). By calculating the concentration in the food, the total intake can be estimated and a dose calculated as a result of the annual intake. This report compiles transfer factors for radiological risk assessments, using common food products, including meats, eggs, and… more

The 75As(n,2n) Cross Sections into the 74As Isomer and Ground State

Description: The {sup 75}As(n, 2n) cross section for the population of the T{sub 1/2} = 26.8-ns isomer at E{sub x} = 259.3 keV in {sup 74}As has been measured as a function of incident neutron energy, from threshold to E{sub n} = 20 MeV. The cross section was measured using the GEANIE spectrometer at LANSCE/WNR. For convenience, the {sup 75}As(n, 2n) population cross section for the {sup 74}As ground state has been deduced as the difference between the previously-known (n, 2n) reaction cross section and the… more

Initial Estimate of the 237U(n,f) Cross Section for 0.1 (less than) En (MeV) (less than or equal to) 20

Description: In response to a request for a {sup 237}U(n,f) cross section evaluation up to E{sub n} = 20 MeV, they have married a data set from the previous reliable estimate [1-3] of the cross section up to E{sub n} = 2.5 MeV, to an estimate of the remaining cross section up to E{sub n} = 20 MeV, deduced from simple physics arguments. This straw-man, work-in-progress estimate of the {sup 237}U(n,f) cross section is intended to be used in sensitivity-test comparisons to other evaluations of the cross sectio… more

Analysis of CASES-99 Lidar and Turbulence Data in Support of Wind Turbine Effects: April 1, 2001 to Januay 31, 2003

Description: The nocturnal low-level jet (LLJ) of the Great Plains of the central United States has been identified as a promising source of high-momentum wind flow for wind energy. The acceleration of the winds after sunset above the surface produces a jet profile in the wind velocity, with maximum speeds that often exceed 10 m s-1 or more at heights near 100 m or more. These high wind speeds are advantageous for wind energy generation. The high speeds aloft, however, also produce a region of high shear be… more
