Typical influences of selected circular knitted fabric and machinery variables on dyed and finished knitted fabrics;

The metrical equipment in the lab of meteorological instrument made by different manufactures,which used different specialized interfaces,communication protocols and have not provided the interface for the network.

A qualitative analysis for modulus value stability based on Monte Carlo method (Ⅲ): Effect of metering equipment error of raw materials on modulus value stability of raw meal;

The correlated parameters are executed with sensitivity analysis,the obtained curves show the rationality of chosen design variables and got optimal result,however,sensitivity analysis with two economy parameters i.

In this article new frequency function will be minimized to solve time varying system identification of design variables for frequency region.

In addition, to avoid evaluate transcend equation,joggle angle is regarded as one of design variables instead of addendum modification coefficient.

he paper first analyses the main reason why optimal design for structure hast been widely applied, and then present a method that can greatly reduce the number of design variables and improves the efficiency of structural optimazation.

These problems are the determination of design parameters ,the reduction of design variables ,the selection of optimization methods ,the stability and the robustness of design results and the route to the dynamic design of practical engineering structures.
