With the continuous development and popularization of network equipment and services, people's dependence on cyberspace is becoming stronger and stronger, and the importance of network security is becoming more and more prominent. Mimic defense is based on the system architecture of dynamic heterogeneous redundancy. Data is sent to multiple heterogeneous functional equivalents through the input agents, and then the response of heterogeneous functional equivalents is judged according to a certain arbitration policy by the output agent. The abnormal output of a functional equivalent can be effectively eliminated, enabling the system to achieve intrusion prevention against unknown system vulnerabilities or backdoors. This paper analyzes the effect of the isomorphism of functional equivalents on system security, and proposes a mimic method based on the equivalence of mimicry maximization. Experiments have shown that the effectiveness of security defense can be significantly improved.

In order to develop and utilize new energy, wind energy has received more and more attention. A novel type of vertical axis named the fish-bionic wind wheel (FBWW) was proposed in this paper, and the outline of wind wheel was constructed by curve of Fourier fitting and polynomial equations. The relationship between wind speed and the FBWW characteristics was determined by computational fluid dynamics (CFD) simulation and wind tunnel test. The results show that the wind speed is in the range of Sm/s~10m/s, and the FBWW reaches the maximum efficiency. In the wind speed range of 7m/s to 13m/s, the FBWW torque shows a monotonous increase. The wind speed has a certain influence on the wind energy utilization rate of the FBWW.

As a critical factor for the resources acquisition of water and nutrient, the root system responding the in-situ environment includes root length, root weight, root branching density, root hair density etc. Fractal geometry has been used to describe the complexity of many objects in nature such as leaves, trees, sea shores and so on. The aim of this study is to use fractal geometry in examining the developmental responses of the root system under a heavy metal stress, namely, Cd stress. Based on fractal geometry, fractal dimension (FD) was evaluated and comparison with conventional measurements was done. Wheat plants that were grown in hydroculture system for three weeks under different concentrations, 0, 0.001, 0.01, and 0.05mM of Cd were used as samples. Photographs of the entire root systems of the plants were taken weekly with a digital camera for three consecutive weeks, and then, they were used for analysis. The analysis of the images involved segmentation and skeletonization followed by application of box-counting method to calculate the FD. The changes of FD in response to different Cd stresses were examined. The results indicate that FDs under Cd stress were lower than those for the control condition. The results demonstrate that FD can be an effective measure to describe the changes in the structural development of the root system under heavy metal stress. It was also found that FD was more sensitive to changes under the influence of the heavy metals than those of the conventional measurements.
