Based on the effective width of strip footing and the plastic limit analysis theory,a variable static stress field and a lower bound solution of strip footing under combined loading were presented.

Based on the Meyerhof′s effective width of strip footing and the plastic limit analysis theory,an upper-bound solution of strip footing under vertical,horizontal and moment loads due to combined loading is presented by constructing variable permissive moving field.

Overlap factor and equivalent width of cut for regenerative chatter in 3 D cutting;

Aimed at the quality of service required by real-time service,an effective bandwidth calculating method for self-similar traffic is presented to provide guaranteed packet loss probability and maximum delay.

Based on effective bandwidth theory, the length of scheduling period is on-line adjusted according to current residual system resources and variable range of period tolerance.

Due to the requirement of engineering application and theory analysis,it is necessary to compute α,β,γ filters′ equivalent bandwidth.

Based on the deep analysis of the TCP connection, this paper gives the equivalent bandwidth concept and deduces its analytical expression.

It can acquire multiplex gain from both in the source and across the source by evaluating the equivalent bandwidth of self-similar traffic.

This relaxation mechanism is based on the fact that the model of the spin wave resonance in the grain-surface-layer successfully explained the behaviors of off-resonance effective linewidth.
