Structural Integrity Meter Verification is a robust new Coriolis verification technology which uses the onboard electronics to very accurately measure the stiffness of the flowtubes. The flow tube stiffness is directly related to the flow calibration factor and is uninfluenced by process conditions. Meter Verification compares the measured stiffness to the factory baseline stiffness to confirm ...

Background: The angular dependency of response for TLD cards may cause deviation from its true value on the results of environmental dosimetry, since TLDs may be exposed to radiation at different angles of incidence from the surrounding area.Objective: A 3D setting of TLD cards has been calibrated isotropically in a standard radiation field to evaluate the improvement of the accuracy of meas...

Boresight Calibration of integrated imaging/inertial systems is a critical factor for map production, especially in the case of digital imaging sensors. The focus of this paper is therefore on boresight calibration using different approaches. Two boresight calibration approaches are presented, namely the airborne and the terrestrial approach. Traditional airborne boresight calibration has been ...

A new approach to self-calibrate a camera-equipped robot manipulator is proposed in this paper. Self-calibration here means that the camera-robot system is capable of determining its geometric parameters without any external measurements and/or ground truth calibration data. With the proposed approach, one is able to identify all the rotational parameters and, up to a scale factor, all the tran...

direct orthogonal signal correction(dosc) and savitzky-golay filters (sgf) were applied as preprocessing methods on the original and first derivative absorbance data. principle component regression (pcr), partial least squares (pls) and iterative target transformation factor analysis (ittfa), were used in spectrophotometric simultaneous determination of heavy divalent metal ions, lead, zinc,mer...

We present the bidirectional reflectance of a Labsphere calibration plaque, both dry and submerged in water, at normal illumination. The measurements indicate that when submerged in water, the Labsphere calibration plaque has a higher reflectance value than when dry at viewing angles below 55 degrees . The results are presented in the form of a reflectance factor and are useful for calibrating ...

Introduction In this work, we propose a novel method to apply segmented GRAPPA [1, 2] when only limited auto-calibration signal (ACS) lines are available. As pointed out in [3], segmented GRAPPA is superior to GRAPPA [4] but requires significant amount of ACS lines. To overcome this drawback, a total variation (TV) regularized GRAPPA technique is used to produce a full calibration k-space with ...

For activity quantification based on planar scintillation camera measurements, photon attenuation is an important factor that needs to be corrected for in a patient- and organ-specific manner. One possibility for obtaining attenuation correction maps is to use X-ray CT scout images. Since the intensity of scout images is in relative numbers, their image values need to be multiplied by a factor ...
