A Convergence Analysis of Unconstrained and Bound Constrained Evolutionary Pattern Search (open access)

A Convergence Analysis of Unconstrained and Bound Constrained Evolutionary Pattern Search

The authors present and analyze a class of evolutionary algorithms for unconstrained and bound constrained optimization on R{sup n}: evolutionary pattern search algorithms (EPSAs). EPSAs adaptively modify the step size of the mutation operator in response to the success of previous optimization steps. The design of EPSAs is inspired by recent analyses of pattern search methods. They show that EPSAs can be cast as stochastic pattern search methods, and they use this observation to prove that EpSAs have a probabilistic weak stationary point convergence theory. This work provides the first convergence analysis for a class of evolutionary algorithms that guarantees convergence almost surely to a stationary point of a nonconvex objective function.

Excise Taxes on Alcohol, Tobacco, and Gasoline: History and Inflation-Adjusted Rates

This report provides inflation-adjusted excise tax rates for alcohol, tobacco, and gasoline products. The base for computation is November 1951. All of the above cited commodities had rate increases effective for that date under the Revenue Act of 1951. The adjustments show what the tax rates would be in 1999 if they had been increased to reflect inflation

Heat Treat of 3Z Valve Piston (open access)

Heat Treat of 3Z Valve Piston

To improve the processing of 3Z valve pistons in LF7 assemblies, material qualities are being investigated. After a review of the fracture toughness curve, it was noted that a change of a few degrees variation from the 900 F called for by the drawing would affect the fracture toughness of the product. After this observation it was decided to determine how close to the 900 F the parts were heat-treated. The subsequent study indicated that Federal Manufacturing & Technologies (FM&T) equipment held the product at 900 F {+-} 1.8 F.

In-situ, real-time, studies of film growth processes using ion scattering and direct recoil spectroscopy techniques. (open access)

In-situ, real-time, studies of film growth processes using ion scattering and direct recoil spectroscopy techniques.

Time-of-flight ion scattering and recoil spectroscopy (TOF-ISARS) enables the characterization of the composition and structure of surfaces with 1-2 monolayer specificity. It will be shown that surface analysis is possible at ambient pressures greater than 3 mTorr using TOF-ISARS techniques; allowing for real-time, in situ studies of film growth processes. TOF-ISARS comprises three analytical techniques: ion scattering spectroscopy (ISS), which detects the backscattered primary ion beam; direct recoil spectroscopy (DRS), which detects the surface species recoiled into the forward scattering direction; and mass spectroscopy of recoiled ions (MSRI), which is 3 variant of DRS capable of isotopic resolution for all surface species--including H and He. The advantages and limitations of each of these techniques will be discussed. The use of the three TOF-ISARS methods for real-time, in situ film growth studies at high ambient pressures will be illustrated. It will be shown that MSRI analysis is possible during sputter deposition. It will be also be demonstrated that the analyzer used for MSRI can also be used for time of flight secondary ion mass spectroscopy (TOF-SIMS) under high vacuum conditions. The use of a single analyzer to perform the complimentary surface analytical techniques of MSRI and SIMS is unique. The dwd …
