21. Selection of Calibration Particles for Scanning Surface Inspection Systems
Published: 8/8/1996
Authors: George William Mulholland, Nelson P Bryner, Walter S Liggett Jr, B W Scheer, R. K. Goodall
Abstract: In response to the semiconductor industry's need for both smaller calibration particles and more accurately sized larger particles, a joint SEMATECH, National Institute of Standards and Technology, and VLSI Standards, Inc. project was initiated to ac ...

22. Assessment of Error Sources in Rockwell Hardness Measurements
Published: Date unknown
Authors: Walter S Liggett Jr, Samuel Rea Low III, David J Pitchure, Jun-Feng Song
Abstract: In the use of hardness test blocks, the uncertainty due to block non-uniformity can be reduced if one is willing to make measurements at specified locations on the blocks. Statistical methods for achieving this reduction are explained in this paper. ...

23. Data Mining Electron Microscope Images to Estimate a Particle Size Distribution
Published: Date unknown
Authors: Walter S Liggett Jr, Robert A Fletcher
Abstract: The application considered involves density estimation, spatial prediction, and sizing error. The goal is estimation of a particle size distribution; the data are scanning electron microscope (SEM) images that constitute a sample of a filter surface ...

24. Data-Driven and Peak-Based Feature Selection In Serum Protein Mass Spectrometry
Published: Date unknown
Authors: Walter S Liggett Jr, Peter E. Dr. Barker, O J Semmes, L H Cazares
Abstract: Consider functional canonical correlation analysis (CCA) applied to disjoint sections of lengthy protein mass spectra for the purpose of finding long-distance correlation structure. The relations between the CCA weight functions, which are derived f ...

25. Measurement Reliability in the Early States of Biomarker Development
Published: Date unknown
Authors: Walter S Liggett Jr, Peter E. Dr. Barker, J Semmes
Abstract: Analytical instruments with functional responses such as SELDI-TOF mass spectra offer a basis for biomarker development. This paper describes an approach to improving measurement reliability, that is, to improving the consistency of the instrument ...

26. Parameter Design for Measurement Protocols by Latent Variable Methods
Published: Date unknown
Author: Walter S Liggett Jr
Abstract: We present an approach to measurement system parameter design that does not require the values of the experimental units be known. The approach does require experimental units grouped in classes, a necessity when protocol execution alters the unit. ...
