Status Review of California’s Low Carbon Fuel Standard (Revised Version)

This status review of California's Low Carbon Fuel Standard (LCFS) summarizes actions regarding the standard. Greenhouse gases are subject to regulation under the LCFS. Statistics are provided on credits and the price of credits; average fuel carbon intensity; ethanol production and consumption; the number and vehicle miles of travel of plug-in electric vehicles; and, gasoline prices. The California Air Resources Board will vote on re-adoption of the LCFS in July 2015 and major court decisions on LCFS, some leading to the need for the re-adoption vote, are summarized

Study of Acoustic Emisison Characteristics for Fracture Assessment

Inspection for structural integrity of the Space Shuttle Solid Rocket Boosters (SRBs) is of paramount importance to mission safety. After every shuttle launch, the booster rockets are retrieved and an extensive inspection operation performed to detect any mission-related anomaly. If damage occurs to the structure during shuttle mission, Acoustic Emission (AE) from cracks could be monitored and used as a means for initial screening to identify potential damage locations for selective postlaunch inspection

Paper Session I-C - Shuttle Component Structural Integrity Monitoring in Harsh Noise Environment

Inspection for structural integrity of the Space Shuttle Solid Rocket Boosters (SRBs) is of paramount importance to mission safety. After every shuttle launch, the booster rockets are retrieved and an extensive inspection performed to components and welds to detect any degradation that occured as a result of the mission flight. The cost of refurbishment related to preparation, actual inspection, and reassembly after inspection, is substantial. It is a major factor concerning availability of these crucial components

High Reynolds number and turbulence effects on aerodynamics and heat transfer in a turbine cascade

Experimental data on pressure distribution and heat transfer on a turbine airfoil were obtained over a range of Reynolds numbers from 0.75 to 7.5 x 10 exp 6 and a range of turbulence intensities from 1.8 to about 15 percent. The purpose of this study was to obtain fundamental heat transfer and pressure distribution data over a wide range of high Reynolds numbers and to extend the heat transfer data base to include the range of Reynolds numbers encountered in the Space Shuttle main engine (SSME) turbopump turbines. Specifically, the study aimed to determine (1) the effect of Reynolds number on heat transfer, (2) the effect of upstream turbulence on heat transfer and pressure distribution, and (3) the relationship between heat transfer at high Reynolds numbers and the current data base. The results of this study indicated that Reynolds number and turbulence intensity have a large effect on both the transition from laminar to turbulent flow and the resulting heat transfer. For a given turbulence intensity, heat transfer for all Reynolds numbers at the leading edge can be correlated with the Frossling number developed for lower Reynolds numbers. For a given turbulence intensity, heat transfer for the airfoil surfaces downstream of the leading edge can be approximately correlated with a dimensionless parameter. Comparison of the experimental results were also made with a numerical solution from a two-dimensional Navier-Stokes code

SEAPAK user's guide, version 2.0. Volume 1: System description

The SEAPAK is a user interactive satellite data analysis package that was developed for the processing and interpretation of Nimbus-7/Coastal Zone Color Scanner (CZCS) and the NOAA Advanced Very High Resolution Radiometer (AVHRR) data. Significant revisions were made to version 1.0 of the guide, and the ancillary environmental data analysis module was expanded. The package continues to emphasize user friendliness and user interactive data analyses. Additionally, because the scientific goals of the ocean color research being conducted have shifted to large space and time scales, batch processing capabilities for both satellite and ancillary environmental data analyses were enhanced, thus allowing large quantities of data to be ingested and analyzed in background

SEAPAK user's guide, version 2.0. Volume 2: Descriptions of programs

The SEAPAK is a user-interactive satellite data analysis package that was developed for the processing and interpretation of Nimbus-7/Coastal Zone Color Scanner (CZCS) and the NOAA Advanced Very High Resolution Radiometer (AVHRR) data. Significant revisions were made since version 1.0, and the ancillary environmental data analysis module was greatly expanded. The package continues to be user friendly and user interactive. Also, because the scientific goals of the ocean color research being conducted have shifted to large space and time scales, batch processing capabilities for both satellite and ancillary environmental data analyses were enhanced, thus allowing for large quantities of data to be ingested and analyzed
