✦ Synopsis


Ahstraet

A sunple non-bear regressIon method for Ion-selectwe electrodes (ISES) was developed It can replace Newton's Iterative method which has dwergence problems The convergence Interval of Newton's lteratwe method for IS& was also studled and was determmed ConsIderable errors m the slope may be caused by lmear regression based on the Nemst equation under some con&tlons (e g , low detectron hmlt, msufficlent measurement pomts) and the non-hnear regressIon based on the Mkolsky equation IS strongly recommended as a regressIon method for ISES and some other chenucal sensors based on potentlometry

For many allometry problems, morphological variables, \(x\) and \(y\), can be transformed using logarithms and linear techniques used to estimate parameters and compare samples. Because both \(x\) and \(y\) are subject to errors, Model II regression has been advocated for such analyses. When data, s

A simple way to develop non-linear PLS models is presented, INLR (implicit non-linear latent variable regression). The paper shows that by simply added squared x-variables x 2 a , both the square and cross terms of the latent variables are implicitly included in the resulting PLS model. This approac

This paper discusses implementation and adaptivity of the Discontinuous Galerkin (DG) "nite element method as applied to linear and non-linear structural dynamic problems. By the DG method, both displacements and velocities are approximated as piecewise bilinear functions in space and time and may b
