Using the single mass-spring model,we study the gaits of a hopping robot for the purpose of minimizing the loss of energy per unit distance covered and present our expressions of energy consumption.

A Product Quality Model for Large-Scale Hot Rolling Mill Based on High-Dimension Input Wavelet Neural Network;

Product quality model based on wavelet relevance vector machine

Partial least square(PLS) regression,a multivariate statistical approach,is applied to the manufacture process quality control,so that quality modeling can be established.

It is proposed that the most important factor in developing an intelligent quality control system is quality modeling and implementing plant–wide quality estim.

According to the characteristics of the pump-pressurized liquid propellant rocket engine, an engine mass model considering performace parameters and structural size was set up by means of theoretic illation, statistics and surface density.

According to the appointed carrier mission and setting the pay load of the space transportation craft(STC) as objective function,energy characteristic model, mass model and orbit model of the hydrogen-oxygen FFSC(Full Flow Staged-Combustion Cycle) were established,and the numerical method was used to optimize the performance parameters.
