Polarimetric calibration accuracy is a key factor in the quantitative use of polarimetric SAR data as well as the design of future SAR system. This paper presents an approach to determine the maximum acceptable distortion level remaining after polarimetric calibration in Polarimetric SAR Interferometry (Pol-InSAR). PolInSAR distortion model of calibration is reviewed and discussed firstly. Then...

We present the stellar calibrator sample and the conversion from instrumental to physical units for the 24 μm channel of the Multiband Imaging Photometer for Spitzer (MIPS). The primary calibrators are A stars, and the calibration factor based on those stars is 4.54× 10 MJy sr (DN/s), with a nominal uncertainty of 2%. We discuss the data-reduction procedures required to attain this accuracy; wi...

To achieve a good clinical outcome in radiotherapy treatment, a certain accuracy in the dose delivered to the patient is required. Therefore, it is necessary to keep the uncertainty in each of the steps of the process inside some acceptable values, which implies a global uncertainty as low as possible. This work is focused on the uncertainty evaluation of absorbed dose to water in the routine c...

Energy companies need efficient procedures to perform market calibration of stochastic models for commodities. If the Black framework is chosen option pricing, bottleneck computation variance asset. commodities are commonly represented by multi-factor linear models, whose obeys a matrix Lyapunov differential equation. In this paper, analytical and numerical methods derive discussed: approach sh...

To measure electromagnetic fields accurately, the calibration of field probes is necessary. In this paper, an accurate lowcost calibration method is presented. However, calibration does not take into account all influencing factors, especially when measuring fields close to the source (e.g., antenna). While measuring, the electromagnetic field will be disturbed by the measurement probes themsel...

We present a new technique to extract the cosmological information from high-redshift supernova data in the presence of calibration errors and extinction due to dust. While in the traditional technique the distance modulus of each supernova is determined separately, in our approach we determine all distance moduli at once, in a process that achieves a significant degree of self-calibration. The...

The effect that measurement error of predictor variables has on regression inference is well known in the statistical literature. However, the influence of measurement error on the ability to quantify relationships between chemical stressors and biological responses has received little attention in ecotoxicology. We present a common data-collection scenario and demonstrate that the relationship...

The aim of this paper is to discuss issues based on foundation design in conjunction with partial factor format for the future development of foundation design codes. That the resistance factor approach is superior to the material factor approach in practical terms for foundation design is concluded. Then, a common procedure from geotechnical investigation/ testing to determine the design geote...
