Abstract: The favorable residual stress field generated by the autofrettage process is increasing the barrel's capacity to withstand pressure during firing—defined as the reloading phase. There are two principal autofrettage ...

Abstract: The design of a gun barrel aims at maximizing its firing power, determined by its safe maximum pressure (SMP)—the maximal allowed firing pressure—which is considerably enhanced by inducing a favorable residual stress field ...

Abstract: This paper presents a technique for quantifying the relationships between observed concentrations of atmospheric sulfate aerosol and their corresponding upstream history of sulfur dioxide emissions, wind speed and mixing ...

Abstract: During the firing of guns, the barrel undergoes two major damaging processes: wear of its inner surface and internal cracking. Barrel's are condemned based on either the increase of their internal diameter due to wear or ...

Abstract: Methods are presented for generating an ensemble of synthetic atmospheric trajectories. These include methods for a set of independent trajectories, and methods for a correlated set of sequential trajectories. The models ...

Abstract: Nonprecipitating low cloud frequencies for 1982 have been extracted from the U.S. Air Force 3-Dimensional Nephanalysis archives for central North America. These data were compiled from satellite, surface and pilot reports ...

Abstract: The dependence of wind interpolation accuracy on vertical shear was investigated using routine and supplemental rawinsonde data collected during the Cross Appalachian Tracer Experiment. Spatial interpolation error distributions ...

Abstract: Routine and supplemental rawinsonde observations collected during the Preliminary Regional Experiment for Storm-Central (PRE-STORM) were analyzed to assess the uncertainty in boundary-layer trajectory calculations due to ...

Abstract: Meteorological observations conducted during the Cross Appalachian Tracer Experiment (CAPTEX) were utilized to quantify the uncertainty in boundary layer trajectory calculations due to low-resolution meteorological data ...

Abstract: For June and July 1975, ozone concentrations throughout the Midwest showed a consistent dependence onwind direction with the highest concentrations associated with winds from the southeast. This systematicpattern suggests ...
