52. Blind Men and Elephants: Six Approaches to TREC Data
Published: 10/28/1998
Authors: D L. Banks, Paul Douglas Over, Nien F Zhang
Abstract: The paper reviews six recent efforts to better understand performance measurements on information retrieval (IR) within the framework of the Text REtrieval Conferences (TREC): analysis of variance, cluster analyses, rank correlations, beadplots, mil ...

54. Statistical Measure for the Sharpness of the SEM Image
Published: 7/1/1997
Authors: Nien F Zhang, Michael T Postek, Robert D. Larrabee
Abstract: Fully automated or semi-automated scanning electron microscopes (SEM) are now commonly used in semiconductor production and other forms of manufacturing. Testing and proving that the instrument is performing at a satisfactory level of sharpness is an ...

56. New Algorithm for the Measurement of Pitch in Metrology Instruments
Published: 5/1/1996
Authors: Nien F Zhang, Michael T Postek, Robert D. Larrabee, L Carroll, William J. Keery
Abstract: Traditionally, the measurement of pitch in metrology instruments is thought to be a benign self-compensating function. However, as the measurement uncertainty of metrology instruments is pushed to the nanometer level, evaluation of the performance of ...

57. Statistical Models for Estimating the Measurement of Pitch in Metrology Instruments
Published: 1/1/1996
Authors: Nien F Zhang, Michael T Postek, Robert D. Larrabee
Abstract: The measurement of pitch in metrology instruments is through to be a benign self-compensating function. In the course of issuing the new scanning electron microscope standard SRM 2090, a new algorithm for the measurement of pitch was developed. This ...

59. Analysis of Sensitivity of VCCTL Measurements to Various Input Quantities
Published: Date unknown
Authors: Adriana Hornikova, Blaza Toman, Nien F Zhang, Hung-Kung Liu, Robert Charles Hagwood, Edward Joseph Garboczi, Jeffrey W Bullard
Abstract: Virtual measurements are the outputs of well-defined mathematical models based on theoretical principles and simulation algorithms. The VCCTL (Virtual Cement and Concrete Testing Laboratory) is a software system built by the Material and Construction ...

60. Effects of Using Generalized Moving Averages of Stationary Process Data and Their Applications
Published: Date unknown
Author: Nien F Zhang
Abstract: Due to the high frequency sampling of on-line data acquisition systems, most of the on-line data are auto correlated. The autocorrelation of the process data has impacts on the applications of statistical analysis methodologies since the assumption ...
