The dynamic constitutive relation of redeposited loess in Gannan region is investigated based on the dynamic triaxial tests. The model parameters are obtained, and the behaviors of dynamic shear modulus ratio and damping...

The shear modulus and damping ratio of EPS composite soil, as a kind of artificial filling material, are the key parameters to analyze the dynamic stability of embankment. 15 cyclic torsional tests are conducted on the h...

In order to study the earthquake seismic behaviors of ecological bags-reinforced wall, the large-scale shaking table model tests are performed. It is shown that the frequency decreases and the damping ratio increases wit...

A couple of key test technologies for dynamic centrifuge modeling and the permanent deformation responses of saturated clay to cyclic loading are introduced. The rigid pavement is used in the model system. The subgrade b...

Cultures of hybridoma cells in bioreactors are commonly used to produce monoclonal antibodies. As an alternative to nonlinear model predictive control, which has recently been applied successfully to optimize the process...

The secular approximation of the hierarchical three body systems has been proven to be very useful in addressing many astrophysical systems, from planets to stars to black holes. In such a system, two objects are on a ti...
