Learning to Recognize Distributional Functions

October 12, 2021

Author(s)
Joy Dunkers, Sandra M. Da Silva, Stephanie Servetas, James J. Filliben, Guilherme L. Pinheiro, Nancy Lin
Making reliable measurements of antimicrobial killing efficacy requires careful consideration of the sources of biological variability, measurement bias and error throughout the entire workflow. For ultraviolet-C (UV-C) disinfection, killing efficacy is

DESIGN OF AN INTELLIGENT PYTHON CODE FOR VALIDATING CRACK GROWTH EXPONENT BY MONITORING A CRACK OF ZIG-ZAG SHAPE IN A CRACKED PIPE

July 27, 2019
Author(s)
Jeffrey T. Fong, Pedro V. Marcal, Robert B. Rainsberger, Nathanael A. Heckert, James J. Filliben
When a small crack is detected in a pressure vessel or piping, we can estimate the fatigue life of the vessel or piping by applying the classical law of fracture mechanics for crack growth if we are certain that the crack growth exponent is correct and the

Sensitivity Analysis Affecting the Calibration of Heat-Flow-Meter Apparatus

July 1, 2019
Author(s)
Robert R. Zarr, Sergio A. Carvajal, James J. Filliben
Results and analysis of a sensitivity study of four procedural variables on the calibration response of two commercial heat-flow-meter apparatus in compliance with ASTM Test Method C 518 are presented. The apparatus ranged in plate size from 305 mm by 305
