Nowadays it is difficult to attract undergraduate students' interesting to put sufficient time to learn major courses in China, which are too hard for them to quick grasp and fully understanding. Here we report a digital education reform for improving interactions between students and instructors, in which we transform the abstract, obscure and boring knowledge, such as physical, mathematical, electronic or optical concepts into direct and dynamic 3-D model and flash. Therefore, this method can convert theoretical concepts into easy understanding pictures. Our several years' experience shows that this education mode can make students' willing to think and practice, then it is helpful for attracting their learning interests. Most students benefit from this education mode which can greatly enhance their understanding abilities.

A concise method for modeling nonstationary fatigue loading histories is presented. The minimum number of model parameters is achieved by fitting the variations in mean and variance by a truncated Fourier series. An autoregressive moving average (ARMA) model is used to describe the stationary component. Justification of the method is made by comparing fatigue relevant parameters obtained when subjected to the original and reconstructed histories. In spite of a relatively small number of parameters required, the model is shown to give good results that fall within the bounds predicted by the original history.

The complex human body can be regarded as a grey system based on grey system theory. In this case, the pharmacokinetics mathematical model can be established based on the blood drug concentration data. This is a method of new pharmacokinetics modelling. In this method, there is no need to simplify the complex human body model for a compartment model. Therefore, the established model based on this new method could better reflect the objective reality.

Starting from the impact, which the Ecole Polytechnique had on higher educations in Europe, this paper wants to highlight the role of material models especially for teaching mathematics. Models of ruled surfaces play a prominent role in this narrative, since Gaspard Monge, who taught "Géometrie descriptive" in Paris between 1794 and 1816, already used string models to support his lectures. For this reason, we want to trace especially the history of ruled surface models from the late 18th century to the presence. The investigation focuses on persons, used materials and the major topics. It is known that the axiomatization of mathematics lead to a decay of the meaning of material models in the early 20th century. But at the same time, material mathematical models gained relevance in other disciplines like civil engineering and art. We also want to show, how ruled surfaces can be part of current teaching projects.
