Vortex induced oscillation of underwater pipeline array brings the effects of both the three-component directivity variation of EM transducer and the enhancement of self-noise into the system, thus measurement accuracy of EM signal induced by underwater target is greatly reduced. This paper analyzes the characteristics of moving water and resonance suppression theory, summarizes the optimized method...
The error is in-depth analyzed caused by environment in underwater electromagnetic field measurement of vessel in this paper. The method of error quantitative calculation have been proposed and verified in actual measurement caused by environment in underwater electromagnetic field measurement of vessel by increasing environmental monitoring units and the calculation method of environmental electromagnetic...
Hopping sequence used in VHF Hopping Radio ought to have a longer period, therefore the partial and dynamic properties of balance and Hamming correlation are more essential in practical hopping sequences application. Based on m sequence of GF(p) structure we had designed hopping sequence. The paper uses χ2 statistic test for partial of hopping sequence homogeneity, frequency interval stay, run-length,...
The development and the composition of table tennis robot are introduced. Based on the moving characteristic of table tennis, a sort of 3-RPUR+RP 5-DOF hybrid robotic arm is put forward, which can perform three translational DOFS and two rotational DOFS. By using D-H parameter method and XYZ Euler angle, the kinematic inverse solution of the hybrid robotic arm is analyzed and the pose of the racket...
