This paper put forward two graphic solutions to determine the minimal distance between the line outlet of cable fastened tower and the cable,with the graphic principles of auxiliary transform of graphic geometry,in the design of insulated distribution of high voltage circuits.

Precision of spatial interpolation for forest duff layer depth based on secondary variable

The selection of secondary variable is crucial in soft sensor.

The selection of the secondary variable consists in the selection of the type, the number and the detect spot.

Proposes an algorithm of bi-iteration subspace tracking using instrumental variable,and it is a bi-iterate rank-one update model.

Under the assumption that the sources are narrow-band and their temporal correlation is longer than that of noise,a new method to solve this problem is proposed which combines the methods of instrumental variable and unitary transformation.

As an important identification method,the instrumental variable method can give the unbiased parameter estimation for systems with colored noises and unknown noise models.
