The species of optimized sample set is selected as the template of transmitter identification, so that the individual communication transmitter identification can be realized. The turn-on signals of four transmitters are used in the simulation. The experimental results show that the multifractal character of transmitter transient signals is an effective character of individual transmitter identification.展开更多

More attention is paid to the platform with prism shape jacket because of its more possibly excessive vibration in service than that of the jacket platform with slant piles. Numerical simulations are compared with the results from actual platform test and an effective strengthening technique is proposed. The conclusion of the paper may be taken as the basis of following control work.It also gives some guidance to the future design of the fixed platform with prism shape jacket.展开更多

In addition, the dual challenges of patients' awareness of rights protection and the nursing industry. According to the practical survey, it is found that during the education and training for nursing staff, they often attach importance to professionalism and morality, which is not conducive to the healthy development of the nursing industry. Therefore, this paper will start based on the nursing theory, analyze the problem of modern nursing moral education, and try to put forward the corresponding countermeasures and suggestions, to build a perfect nursing moral education system together.展开更多
