The degree to which measurement accuracy in a vector network analyzer can be improved through error correction is dependent on a number of factors. Modern error correction methods have improved the system accuracy and simplified the calibration procedure. Methods are in place to determine the accuracy of error corrected measurements. And the quality of the calibration standards is key to system...

since 1984 iranian banks has been operating under islamic principles. this paper investigates dynamics of loans and the difficulties that iranian banking system was facing. during the period of islamic banking in iran, banks experienced a significant increase in the supply of loans. many factors have affected the behavior of banks in lending operations, the most important of which include rate ...

In order to correct attenuated millimeter-wavelength (Ka-band) radar data and address the problem of instability, an attenuation correction methodology (attenuation correction with variation trend constraint; VTC) was developed. Using synchronous observation conditions and multi-band radars, the VTC method adopts the variation trends of reflectivity in X-band radar data captured with wavelet tr...

background: in treating patients with radiation, the degree of accuracy for the delivery of tumor dose is recommended to be within ± 5% by icru in report 24. the experimental studies have shown that the presence of low-density inhomogeneity in areas such as the lung can lead to a greater than 30% change in the water dose data. therefore, inhomogeneity corrections should be used in treatment pla...

purpose : to identify any factors that may predict successful levator resection in blepharoptosis correction methods : the hospital records of 52 consecutive patients undergoing anterior levator resection for unilateral congenital blepharoptosis were reviewed. successful result was defined a lid level within 1 mm of the fellow eye 1 year after surgery. we studied the effect of levator function,...

• Variation between measurements may be reduced if sampling is not random • Fixed factors can reduce variation • Replicates are repeated measurements from within an experimental unit • Replication means that samples can no longer be considered random • Comparisons of replicated values require correction, usually by reducing the effect of sample size • Correction requires knowledge of the intra-...
