In this paper, a three-level DTC system is presented based on single vector selection table which resolves the problems of voltage unbalance of neutral point and high dv/dt of output voltage, typical in multilevel inverters.

A method of calculating angles of a cutting tool with unit vectors;

This paper designed and trained a three-layer f ee dforward neural network to estimate the actual rotor flux and unit vector for d irect vector controlled induction motor speed drive.

The change rate of unit vector r 0,θ 0,β 0 of spherical and cylindrical coordinate is drawn with θ,β changing in the graphic directly and at the same time the operate procedure three dimensinal cableauon on the screen is listed.

An improvement of the vector basis functions of quadratic hexahedral edge elements is presented.

The paper puts forward a global model oriented integrating vector processing, which uses super Spaghetti data structure with subtopological features to organize the vector spatial data, follows the industry standards implemented by integrating task to rebuild attitude source model and to build the topological information model composed of attitude parameters and spatial data with hidden to.

The magnetization curves of single crystalline Si steel in different direction have been calculated using single vector model.
