Research on water flooding effect improved by vectorial well arrangement for reservoirs with permeability heterogeneity in plane;

Random Directive Vector Dimension Chain and Its Application in Machine Tool Design and Manufacture;

To solve the problems associated with Direct Torque Control(DTC) of Permanent Magnet Synchronous Mo-tor(PMSM) using conventional voltage space vectors,such as high current,flux and torque ripple,a novel DTC strategy based on voltage space vectors and stator flux linkage sectors subdivision is proposed.

This paper presents a novel speed-sensorless direct torque control method based on vectors subdivision,analyses and compares the performance of traditional six-voltage vector control and twelve-voltage vector s,finally provides the experimental results of the system implementation using dsPIC30F6010.

To overcome problems of steel water continuous casting slag detection system(SWCC-SDS),such as high cost and equipment inconvenience,a new SDS based on vector quantization(VQ) technology was put forward.

An integral projection algorithm for Vector Quantization(VQ) is proposed in this paper,integral projection is used in every 4×4 block firstly,and then carry on vector quantity with the integral codebook.

Vector Quantization(VQ)is one of the popular codebook design methods for text-independent speaker identification.
