... A complete calibration on any Guarded or Calibrated Hot Box is critical for improving the accuracy of U -factor measurements of fenestration products. Any heat transfer that does not occur directly through the test specimen should be determined from the results of detailed calibration...

... expansion from irreversible deformation arising from creep under the applied load or changes in dimensions due to relaxation of orientation. The effect of experimental variables and calibration are described and the application of the technique to study the glass-rubber transition and melting of polymers...

... sensor that is separated from the specimen, differences in specimen conditions have no effect on the observed temperature. In this situation, the temperature sensor is calibrated by synchronization to an observed material transition. By using a TGA with a direct contact thermal sensor this study shows...

... In order to investigate the stability of an impact testing machine between ordinary calibrations, impact tests have been performed on a regular basis using specimens from an isolated batch of material. A nickel based alloy, W-Nr. 1.4563, was chosen due to its ageing stability. The material...

..., nuclear gauge density measurement methods are becoming the preferred standard around the world. Requirements dictate that gauges be verified or calibrated once every 12 to 18 months. Presently, there are no field portable devices available for verification of the gauge calibration. Also, the density...

A Calibration Program involves controlling the accuracy of the instruments that control the process. If the calibration...

... hydrogeologic framework and physical processes. The uniqueness problem should be addressed by using measured hydraulic conductivities, calibrating to ground-water flow rates as well as hydraulic heads, and/or calibrating to data collected during multiple distinct hydrologic conditions. Over-calibration can...

... A three-dimensional ground water flow model was developed and calibrated for use as a quantitative tool for the evaluation of several potential ground water remedial alternatives during the On-Post Feasibility Study for the Rocky Mountain Arsenal. The USGS MODFLOW code was implemented...

... Model application verification is important because it establishes the predictive capability of the model. In the verification process, the model conceptualization and parameter values determined during the calibration process are used to simulate independent conditions for which a set of field...
