An effective method was proposed to represent the distribution of the envelope interference factor (EIF) of the interference effects among three tall buildings.

Here are presented a numerical simulation method of the 8m×6m wind tunnel wall interference,the calculated lift interference factor,and the comparison of the numerical results with the data presently used in 8m×6m tunnel and the one from the reference 2.

The equation of interference factor for switched beam system, and a calculating method, which demonstrates the relationship between the outage probability, the sensitivity of the base station receiver, the maximum transmission power of the mobile station, the signal-to- interference ratio (SIR), the coverage radius of the cell and the capacity, have been presented.

Improved Quantum-behaved Particle Swarm Optimization Algorithm with Disturbance and Its Application;

So it introduced a disturbance to avoid the premature of the algorithm.

To avoid the state of sub-optimal,a disturbing factor had been used to get the best feature weights.

For analyzing the system characteristics and patterns of vibration, the introduction of amplification factor and the stability margin helps the analysis and evaluation of the vibration of the powertrain mounting system.

2) Calibration for amplitude of electromagnetic torque : Collect displacement response amplitudes form the measured system and find the magnification factor,then the amplitude of the .

Aimed at the actual engineering requirement,this paper puts forward little-character-toggle brace which is a new energy dissipation brace,its magnification factor expression and calculation formula of horizontal control force is also given.
