41. Draft Radioanalytical Water and Soil Performance Testing Uncertainty Acceptance Criteria Derived From Historical Mixed-Analyte Performance Evaluation Program Results
Kenneth G. Inn, James J Filliben, James Dahlgran
Radioanalytical performance testing programs provide radioassay laboratories, regulators and the public performance-based evidence that measurement capabilities are in control. Performance acceptance criteria that combine aspects of measurements dif ...
42. Effective and Scalable Uncertainty Evaluation for Large-Scale Complex System Applications
Kevin L Mills, James J Filliben, Junfei Xie, Yan Wan, Yi Zhou, Yu Lei
Effective uncertainty evaluation is a critical step toward real-time and robust decision-making for complex systems in uncertain environments. A Multivariate Probabilistic Collocation Method (M-PCM) was developed to effectively evaluate system uncert ...
43. Energy Performance Sensitivity of a Net-Zero Energy Home to Design and Use Specifications
Joshua D Kneifel, William M Healy, James J Filliben, Matthew T Boyd
44. Evaluation of Low-Contrast Detectability of Iterative Reconstruction across Multiple Institutions, CT Scanner Manufacturers, and Radiation Exposure Levels
Adele P Peskin, Ganesh Saiprasad, James J Filliben, Alden A Dima
Purpose: To evaluate the impact of Iterative Reconstruction (IR) compared with Filtered Back Projection (FBP) using low-contrast objects in phantom images across vendors and exposure levels.
Materials and Methods: Randomized repeat scans of the Gamm ...
45. Evaluation of an Acceptance Sampling Method for 2D/3D Building Plans Derived from 3D Imaging Data
Geraldine S Cheok, Marek Franaszek, James J Filliben
An acceptance sampling method, based on obtaining physical measurements, for accepting 2D building plans generated from 3D imaging data is evaluated and demonstrated using an actual GSA (General Services Administration) facility. The objective of th ...
46. Exploring background variability of a low-level (quartz) gas proportional counter using pulse shape and distribution analysis
George A Klouda, James J Filliben
Low-level gas proportional counting presents special challenges to the measurement process. Generally, measurement systems for this purpose have unique signal-processing capabilities through specialized electronics and software for maintaining a sta ...
47. Extreme Wind Load Estimates Based on the Gumbel Distribution of Dynamic Pressures: An Assessment
Emil Simiu, A N Heckert, James J Filliben, Steven K. Johnson
We present a contribution to the current debate on whether it is more appropriate to fit a Gumbel distribution to the time series of the extreme dynamic pressures (i.e. of the squares of the extreme wind speeds) than to fit an extreme value distribut ...
48. Fire Tests of Single Office Workstations. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5C) ***DRAFT for Public Comments***
National Construction Safety Team Act Reports (NIST NCSTAR)
Thomas J. Ohlemiller, George William Mulholland, Skandakumar Harshanath Nirendra Abeyesekere, James J Filliben, Richard George Gann
Reconstruction of the fires that occurred in the World Trade Center (WTC) 1, 2, and 7 on September 11. 2001, relied heavily on computer simulations because examination of the post-fire premises was not possible and the information from eyewitness acc ...
49. Fragility Curves, Damage Matrices, and Wind-Induced Loss Estimation
James J Filliben, K Gurley, J P Pinelli, Emil Simiu, M Subramanian
This note presents a conceptual framework for the definition of basic damage states and of the corresponding fragility curves and conditional probabilities, and its use for the estimation of damage matrices. The framework is designed with two consid ...
50. Generalizing Face Quality and Factor Measures to Video
Yooyoung Lee, P Jonathon Phillips, James J Filliben, J. Ross Beveridge, Hao H. Zhang
Methods for assessing the impact of factors and image-quality metrics for still face images are well-understood. The extension of these factors and quality measures to faces in video has not, however, been explored. We present a specific methodology ...
