A split anode calorimeter (SAC) has been developed for the measurement of plasma transferred arc (PTA) energy density. novel aspect is use a laser beam with well-defined profile which was first measured using commercial diagnosis system and used to calibrate SAC. The SAC temperature data generated showed same by system. This confirmed accuracy method its suitability measuring distribution an el...

Decision-makers often consult different experts to build reliable forecasts on variables of interest. Combining more opinions and calibrating them to maximize the forecast accuracy is consequently a crucial issue in several economic problems. This paper applies a Bayesian beta mixture model to derive a combined and calibrated density function using random calibration functionals and random comb...

This article describes a multiparameter calibration model, which improves the accuracy of density functional theory (DFT) for the prediction of standard enthalpies of formation for a large set of organic compounds. The model applies atom based, bond based, electronic, and radical environmental correction terms to calibrate the calculated enthalpies of formation at B3LYP/6-31G(d,p) level by a le...

Here we introduce a general class of multiple calibration birth-death tree priors for use in Bayesian phylogenetic inference. All tree priors in this class separate ancestral node heights into a set of "calibrated nodes" and "uncalibrated nodes" such that the marginal distribution of the calibrated nodes is user-specified whereas the density ratio of the birth-death prior is retained for trees ...

The DIII–D Thomson system measures electron density and temperature with eight pulsed ND:YAG lasers along three paths through the plasma vessel. The components of the Thomson system are absolutely calibrated so the measurements can be combined into a single profile from a normalized plasma radius (p) of about 0.1 to the edge of the plasma. A monochromator calibration and opto-electronic calibra...

Measurement of water content in expansive soil using a neutron moisture meter is strongly influenced by the moisture reactive property of this type of soil. It is particularly difficult to calibrate a neutron moisture meter when the dry density changes and the soil cracks during drying. This numerical study models the neutron probe measurement of soil moisture, based on a 7-group diffusion theo...

BACKGROUND Calibrating mammograms to produce a standardized breast density measurement for breast cancer risk analysis requires an accurate spatial measure of the compressed breast thickness. Thickness inaccuracies due to the nominal system readout value and compression paddle orientation induce unacceptable errors in the calibration. METHOD A thickness correction was developed and evaluated ...

A new calibration technique was developed for Implementation with microwave moisture sensors. The calibration permittivity function used for this purpose allows computation of moisture content in granular materials with significant differences In shape, dimensions, and composition, independent of bulk density and with temperature compensation. A three dimensional (3-13) representation is used t...
