In the scheme of making the track of stator flux approximate circle, the relevant vector of inverter switch is selected by calculating in real time the error of torque and flux and linking the dimensional position of stator flux.
The mathematic proof of said proposition can be summarized as: the dimensional position of arbitrary points S (x',y',z') on 3-D arbitrary phantom camber can be converted into the coordinate of certain surface stations and thus the result can be obtained.
Some methods based on statistics for dimensional position and data processing by such software as Excel are suggested for the calibration of the dimensional angle shown by a dynamic target using linear matrix CCD and video interpretation.
By dimensional position track of each position point in the process of compressive deformation the section deformation of sealing strip had been described,supplement and proof-test measure for Finite-Element-Analytics had been performed,and the Finite-Element-Analytics reliability of sealing strip had been enhanced.
"Abstract" means the general frame of quantum theory, without reference to a three-dimensional position space, to concepts like particle or field, or to special laws of dynamics.
The experiment results on S-shape and saddle-shape weld seams show that the vision computing method developed in this paper can be used for acquiring weld seam dimensional position information in welding robot system.
This paper deals mainly with finding the solution to essential factors of non-planar geological body's occurence in the interpretation of seismic data. The mathematic proof of said proposition can be summarized as: the dimensional position of arbitrary points S (x',y',z') on 3-D arbitrary phantom camber can be converted into the coordinate of certain surface stations and thus the result can be obtained.
The construction, operation principle and performance of a parallel plate avalanche counter with an active area of 60×400 mm~2 and another one with an activ.e area of 70×140 mm~2 and one dimensional position sensitivity are described in detail. It is discussed how to combine a large solid angle time-of-flight setup by using the two counters described above.
This paper proposes a reconstruction method for the shape of the three-dimensional object. The proposed method is the photometric stereo method utilizing several gray-scale images obtained by a fixed camera and a light -source with varying position. In the past method, the surface shape of the objectes restroed based on the gradient of the object surface ditermined by the photometric stereo meth-od , where other methods must be combined in order to determine the three-dimensional positi...
