Calibration Process and Constructions of Extrusion Calibrators
Key Engineering Materials, 2014In the cellular extrusion process, the extrusion head gives the extrudate the desired cross-section shape and dimensions, taking into account the Barus effect and the shrinkage effect. However, if strict requirements are imposed with regard to cross-section shape and dimensions, it is necessary to fix the shape and dimensions by calibrating the ...

Interferometric calibrations and astronomical calibrators
New Astronomy Reviews, 2008Abstract This chapter gives some indications on the selection of suitable astronomical calibrators for interferometric observations. After an introduction to interferometric calibrations, we will focus on the criteria, steps and tools developed by ESO to prepare VLTI observations and to select calibrators.

Journal of Chromatography A, 2007
The bases of multivariate calibration are presented with special attention to some points usually not considered or underevaluated, i.e., the sampling design, the number of samples necessary to obtain a reliable regression model, the effect of noisy predictors, the significance of the parameters used to evaluate the performance ability of the ...

When measuring gas pressure changes in a container, for example an engine cylinder or a gun, by means of a piezoelectric pressure transducer, highly relatively accurate values must be made available in order to obtain the specified absolute accuracy.

Calibration and Partial Calibration on Principal Components
Statistica Sinica, 2017In survey sampling, calibration is a popular tool used to make total estimators consistent with known totals of auxiliary variables and to reduce variance. When the number of auxiliary variables is large, calibration on all the variables may lead to estimators of totals whose mean squared error (MSE) is larger than the MSE of the Horvitz-Thompson ...

A method for calibration of partial discharge calibrators
1998 Conference on Precision Electromagnetic Measurements Digest (Cat. No.98CH36254), 1999A method for calibration of partial discharge calibrators has been developed based on passive integration of the induced charge. The voltage over a known capacitor is measured by a calibrated digital sampling voltmeter and the charge is calculated as the voltage multiplied by the capacitance.

Journal of Personality Assessment, 1974
Summary Ninety-two elderly Ss ranging in age from 57 to 92 were examined in an effort to find a battery of psychological tests which would effectively measure their level of intactness or deterioration of function. Five tests were used: the Rorschach, Gesell Incomplete Man Test, Bender Gestalt, Monroe's Visual Three, and the Color Tree Test.

Perspectives on Science, 1997
Calibration, the use of a surrogate signal to standardize an instrument, is an important strategy for the establishment of the validity of an experimental result. In this paper, I present several examples, typical of physics experiments, that illustrate the adequacy of the surrogate.

Microphones and Their Calibration
2007The condenser microphone continues to be the standard against which other microphones are calibrated. A brief discussion of the theory of the condenser microphone, including its open-circuit voltage, electrical transfer impedance, and mechanical response, is given.
