Torpedo fuze signal denoising is an important action to ensure reliable operation of fuze. Based on the good characteristics of wavelet packet transform (WPT) in signal denoising, the paper used wavelet packet transform to denoise the magnetic fuze signal under a complex background interference, and a simulation of the denoising results with Mat lab is… (More)
We have set up an AUV (autonomous underwater vehicle) space trajectory mathematical model. Then, the fourth-order Runge-Kutta method and full pivoting Gaussian elimination method are used for the computer simulation of different control distance for the different balancing weighting properties. The initial ballistic changes in the law are researched. The… (More)
An improvement is given to the known solution of the index problem for Sturm-Liouville eigenvalues for coupled boundary conditions. The algorithm corresponding the solution is discussed, and numerous numerical examples illustrate the theoretical results and show that the algorithm is valid.
