摘要：
针对传统的蚂蚁算法容易出现早熟和停滞现象,提出一种新型蚂蚁算法(new ant colony algorithm,NACA),即将转移规则、全局信息素灾变规则和局部混合调整信息素规则。选择几个典型TSP问题进行实验。研究结果表明:新型蚂蚁算法一方面提高了算法种群的多样性,同时将轮盘赌算子利用到城市转移规则中,有利于提高算法的收敛速度;另一方面,将种群个体的差分信息应用于局部信息素更新规则中,有利于搜索全局解;最后灾变算子避免算法陷入局部最优,而达到全局最优。新型的蚁群算法具有更强的搜索全局最优解的能力以及更好的稳定性和收敛性,同时为解决其他优化问题提供新的思路。

摘要：
The stability of discrete Hopfield neural networks not only has an important theoretical significance, but also is the foundation of the applications of the networks. Security of the algorithm is discussed.ANN originated has been applied in all aspects of life and production, especially in intelligent control, nonlinear function approximation and environmental parameters forecast assessment. Be similar to the human's brain mechanism, a neural network complete the tasks by the process of learning (training) and use (associative memories). Normally, the neural network can be assured used only after thorough study. According to the dynamic characteristics of the interconnections between nerve cells in Hopfield network, this paper discusses the application of Hopfield network model in gene diagnosis, points out the network problems and puts forward the solutions.

摘要：
In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. In this paper, we propose a novel method to encrypt a gray image based on Arnold transform and Kent mapping. It is a digital medical image encryption algorithm, dual scrambling that based on chaos of pixel position and pixel values. The results of experimental and the statistical analysis show that the histogram of the encryped image is fairly uniform and significantly different from the histogram of the original image. The algorithm improves the traditional image encryption algorithm of image scrambling based on chaos, and it is valid and has good performance.

摘要：
With increasing the degree of state environmental protection, the comprehensive treatment of waste water containing stibium has become a new subject in stibium industry.In this study,we modified diatomite with calcium carbonate,and adsorptived waste water containing stibium using these modified diatomite.Then we explored the quality of modified diatomite,initial concentration,initial pH value,temperature and adsorpting time on adsorption. The adsorption isotherm of stibium fits Langmuir equation.The result shows that the modified diatomite has good adsorption on waste water containing stibium.

摘要：
This paper presents a novel image encryption scheme based on Arnold mapping and Logistic mapping.It is a digital image encryption algorithm,dual scrambling that based on chaos of pixel position and pixel value. First we separated the three channels of a RGB mode image, then transformed them into 3 two dimensional grey images. respectively scramblinged these gray images of the three colour channels or changed their gray value by different methods,finally combined the three ciphertext into a RGB mode image.The results of experiment simulation show that the key space is large enough to resist the brute-force attack,the ciphertext varies sensitively with any minimal changes of the initial secret key and the plaintext. The algorithm improves the traditional image encryption algorithm of image scrambling based on chaos, and it is valid and has good performance.
