In this paper, a series of new algorithms are proposed to estimate the model's coefficients and to
predict future change of the process. On the one hand, it is can be proved that these new
algorithms are outlier-tolerant in the case that there are outliers in sampling series. On the one
hand, these new algorithms are near to the optimal estimators and predictors separately in
normal case. © (2013) Trans Tech Publications, Switzerland.

Abstract: An approach is presented to study the nonlinear dynamic responses to rotating
drill shaft with multi-span supports. Based on the finite element method, the drilling shaft is
modeled as lots of 2-node Timoshenko shaft element model with free-interface that can take the
effect of inertia and shear into consideration. In these cases, the governing equations of drilling
shaft system consist of the coupled linear and nonlinear components. According to the feature of
such systems, a modified transformation is introduced, by means of which the linear degrees of
