In chaotic speech signal encryption, masking is the most direct and convenient method. But the chaotic signals usually have a narrow spectral range in low frequency region. In order to overcome the disadvantage that the higher frequency signals can not be completely covered up, UPT is used to conduct a nonlinear transformation to chaotic signal. After UPT, chaotic types are increased, chaotic characteristics are improved and spectral range is widened. Simulation experiments are done respectively from frequency domain and spectrogram perspectives. The chaos before and after transformation are used to mask speech signal. Decoding experiment is taken on the speech encrypted by transformed chaos. Experiment results show that, after UPT, the encryption effect of speech signal is improved obviously. This method has a high security and a strong anti-attack ability.

The distributions of net-phytoplankton and nutrients were studied in Xiangshan Bay in summer, 2012. The results showed that in summer, the higher values of net-phytoplankton cell abundance were distributed in the areas of Tie port, Huangdun port and Xihu Port. Whereas, the lower values were mainly found in the stations located in the outer area of Xiangshan Bay and the area around Liuheng Island. The content of nitrate in the middle of the bay was higher than that both in the bottom and the entrance of the bay. The concentration of nitrate in the bottom water was a little higher than that in the surface water. The distribution trends of the concentration of nitrite, ammonium and phosphate were almost the same. The higher values were discovered in the sea area of Tie port and Huangdun port and the lower were mainly distributed in the area of the outer Xiangshan Bay and the sea area around Liuheng Island. The distribution trends were almost the same no matter in the surface water or in the bottom water. From the bottom to the middle to the entrance of the bay, the values reduced in turn. In summer, in the water of Xiangshan Bay, net-phytoplankton cell abundance and nutrient (N, P) content didn’t have significant correlation. The concentration of the nutrients (Nitrate, Nitrite, Ammonium and Phosphate) was far more than the minimum threshold of the growth of phytoplankton.

This paper studies the implementation of an ADRC to deal with depth variations of AUV. The depth model of AUV is decoupled from the 6 DOF dynamics function at first. Then, the least square method is introduced to identify the nonlinear open-loop model of AUV offline, and a more accurate depth model that varies with the elevator angle is achieved. Finally, ADRC is applied to the improved depth model with the disturbance of inaccuracy elevator angle and the error of depth measurement. The result confirms that AUV depth model varies with the elevator angle, while the ADRC controller could reject the errors in the depth sensor and the disturbances of mechanical transmission of rudder and the nonlinear variations at different operating points. Comparing to the traditional PID controller, ADRC performs better respectively with these uncertainty. The contribution of the proposed controller would support to the future application to 3D motion control and path tracking of AUV in practice.

The experimental results demonstrate the effectiveness of our algorithm that outperforms the state-of-the-art significantly in precision and recall.

All steel laser welded sandwich plates have found their position in the marine and land vehicles. To implement such design accurately, knowledge about its strength properties and the influence of laser weld dimensions on strength is necessary. In this paper, the over-hanging three point bending tests were conducted on the laser welded web-core steel sandwich plate with various weld dimensions by self-designed device, together with the finite element simulations. The results show that the joint is formed on the first plastic hinge when the load is no longer a linear relationship with the deflection, and the joint cracking when the load reaches the maximum bearing capacity of sandwich plate. The joint yield load and the maximum bearing capacity of the sandwich plates increased with the increasing of weld width. Meanwhile, the mode of failure of sandwich plates also changed: When the weld width is smaller, the mode of failure is joint yield, When the weld width is greater than 3mm, the mode of failure is the combination of partial joint yield, face plate and core plate local yield, while the face plate and core plate yield exists in the whole weld joint. It is necessary to consider the weld width in the design and evaluation of the strength of the laser welded web-core sandwich plate.

Aimed to solve the abandoned wind problem and reduce CO2 emission in the power generation process, this paper put forward a thermal, wind power and pumped storage power station co-operation cost-benefit analysis model. And through a simulation example, found that using pumped storage power station to substitute thermal power as the alternate service for wind power, and absorb underused wind power, can reduce the use of fired units and increase the capacity of grid to absorb wind power, as well as reduce CO2 emission.

So when grid implementing wind power grid connection, should use pumped storage power station as the wind power alternate service to promote wind power grid connection.
