In this paper the deviation function of a threshold value is constructed by the method of variance analysis for wireless network traffic, which is essential for selection of the threshold value.

In the light of the characteristics of designing and manufacturing the micro-gear drives,a designing method called deviation function is proposed in this article.

The traditional linear feature detection algorithm based on Bresenham has been improved via fast Digital Beamlet transform that combining designed deviation function with BD-RDP.

With a drop in formation pressure, the parameters which closely related to the flow coefficient of the exponential deliverability equation are varied, such as gas deviation factor, gas viscosity, reservoir permeability, effective thickness and so on.

On the basis of analysis of the raw materials,using the fineness modulus of aggregate mixture,the deviation factor of synthetic gradation and objective gradation as technical indexes,the best aggregate ratio is attained through the application of computer operations.

Influence of data deviations on the noise character of the reconstructed images in double-random phase encoding method;

A bias factor is commonly used to account for the effect of differences in failure criteria on reliability of pile foundations.

For this purpose,a bias factor defined with respect to S-lgt criterion is introduced;and one.

The friction factor between the prestressed wires and the metallic corrugated pipes and the bias factor of pipleline are determinated.
