摘要:... Subdivision comparison is commonly adopted and matrix method (MM) is used to solve the measurement Eq.. In this paper, the density of test and standard weight rather than the volume were adopted in MM. Details on how to use this method based on Matlab software were presented....

摘要:For a pair of dual (possibly improper) linear programming problems, a family of matrix corrections is studied that ensure the existence of given solutions to these problems. The case of correcting the coefficient matrix and three cases of correcting an augmented coefficient matrix...

摘要:Abstract(#br)New possibilities for the quantitative description of matrix corrections for the absorption of characteristic X-ray radiation and backscattering of primary beam electrons are considered when solving the direct problem of quantitative X-ray spectral microanalysis. It ...

摘要:We propose a method based on the Poynting vector that combines angle-domain imaging and image amplitude correction to overcome the shortcomings of reverse-time migration that cannot handle different angles during wave propagation. First, the local image matrix (LIM) and local ill...

摘要:ABSTRACT(#br)When generalized estimating equations (GEEs) incorporate an unstructured working correlation matrix, the variances of regression parameter estimates can inflate due to the estimation of the correlation parameters. In previous work, an approximation for this inflation...

摘要:Abstract(#br)Correction of the O–D matrix from traffic counts is a classical procedure usually adopted in transport engineering by practitioners for improving the overall reliability of transport models. Recently, Papola and Marzano [Papola, A., Marzano, V., 2006. How can we ...

摘要:...(#br)Difficulties arise when dealing with matrices containing neutron energy moderators such as H and neutron absorbents such as Cl. These components may have a great influence on the fissile mass deduced from the neutron signal measured by ANI. For example, the calibration ...

摘要:Abstract(#br)The linear regression problem is considered as an improper interpolation problem. The metric l 1 is used to correct (approximate) all the initial data. A probabilistic justification of this metric in the case of the exponential noise distribution is given....

摘要:Abstract(#br) Background(#br)BLOSUM matrices belong to the most commonly used substitution matrix series for protein homology search and sequence alignments since their publication in 1992. In 2008, Styczynski et al. discovered miscalculations in the clustering step of the matrix...

摘要:Abstract(#br)A new strategy to carry out the correction of analytical results affected by systematic errors due to the matrix effect is proposed. Two types of external calibrations must be established with the purpose to estimate the matrix effect: solvent calibration (SC) and matrix...
