Published: September 2013

According to many uncertain problems of river eutrophication, a Bayesian hierarchical model was established to predict water quality. We applied the hierarchical method to assess river water quality in an agricultural watershed in eastern China. The procedure followed was developing a hierarchical model relating eutrophication response - the level of chlorophyll (Chla). Through Principal Component Analysis (PCA), five factors strong related with Chla were selected to establish Bayesian hierarchical model to predict the water quality. Results showed that Bayesian hierarchical model was very realistic. Furthermore, in Bayesian perspective, predictions expressed as probabilities, rather than a single value, involving more uncertainty information, can be essential to environmental management and decision-making.

Authors: Li Ting , Dong Wen Yi , Wang Hong Jie , Lin Jin Nan , Ouyang Feng , Zhang Qian
Published: September 2013

Experimental observations of particle capturing through the biological aerated filter bed indicated that air flow rate plays an important role in head loss development by influencing the suspended solids distribution along the depth of the bed as well as the morphology of the deposits. The active height for the SS removal prolonged with the increasing of the air velocity based on the mechanism of first-order kinetics. With the increasing of the superficial air velocity, the effluent SS concentration and the time need to reach the stead-states after backwash both increased. The value of the SS spike in the effluent after backwash at superficial air velocity of 27 m/hr was nearly twice as much as that of 5.4m/hr. Distribution of the deposits at higher air velocity was more uniform. Deposits at lower velocity with air flow rate produced higher head loss gradient. The headloss increased with the increasing of deposits and the increase rate was faster when the deposits exceeded higher value.

An Improved ICA Algorithm Based on the Negative Entropy and Simulated Annealing Algorithm
Authors: Li Hong Yi , Ye Meng , Zhao Di
Published: September 2013

The Independent Component Analysis (ICA) is a classical algorithm for exploring statistically independent non-Gaussian signals from multi-dimensional data, which has a wide range of applications in engineering, for instance, the blind source separation. The classical ICA measures the Gaussian characteristic by kurtosis, which has the following two disadvantages. Firstly, the kurtosis relies on the value of samples, and is not robust to outliers. Secondly, the algorithm often falls into local optima. To address these drawbacks, we replace the kurtosis by negative entropy, utilize the simulated annealing algorithm for optimization, and finally propose an improved ICA algorithm. Experimental results demonstrate that the proposed algorithm outperforms the classical ICA in its robustness to outliers and convergent rate.

Authors: Cao Yong Chun , Shao Ya Bin , Tian Shuang Liang , Cai Zheng Qi
Published: September 2013

Due to many of the clustering algorithms based on GAs suffer from degeneracy and are easy to fall in local optima, a novel dynamic genetic algorithm for clustering problems (DGA) is proposed. The algorithm adopted the variable length coding to represent individuals and processed the parallel crossover operation in the subpopulation with individuals of the same length, which allows the DGA algorithm clustering to explore the search space more effectively and can automatically obtain the proper number of clusters and the proper partition from a given data set; the algorithm used the dynamic crossover probability and adaptive mutation probability, which prevented the dynamic clustering algorithm from getting stuck at a local optimal solution. The clustering results in the experiments on three artificial data sets and two real-life data sets show that the DGA algorithm derives better performance and higher accuracy on clustering problems.

But the main obstacle of spreading eID systems is privacy worrying though they possessed some security and privacy protection measures. In this paper, we provided the enhancement design for protecting citizen privacy in an eID system (taking German eID system as analysis object).Firstly, we suggested to separate authorization eID server and authentication eID server physically to reduce the possibility of personal data breach since eID server could not avoid to be attacked if it was one part of the internet ; Secondly, we put forward that privacy data should be double-encrypted in the stage of applying service, and should be remain encryption except the service program using it, and more importantly , it should be deleted when service is ending ; Thirdly, in order to prevent fake eID server plus fake service provider attack, we devised the authentication flow when citizen access service which let citizen to take part in the authentication process actively. In addition, we present the remote delete personal data process which invoked by citizen to further privacy protection.

Published: September 2013

Rule acquisition is a hot topic in the field of data mining. And the inconsistent information systems are widespread nowadays. However, rules acquisition methods are always the difficulty of rough set theory application in inconsistent decision information systems; So the paper proposes a new rule acquisition method. Firstly, we use maximum distribution reduction method for knowledge reduction in single decision-making inconsistent information system and then we use decision-making resolution matrix and decision-making matrix function to get the decision rules. Finally, we mine the rules from inconsistent decision-making information systems.

Authors: Wen Guo Zhi
Published: September 2013

The traveling salesman problem is analyzed with genetic algorithms. The best route map and tendency of optimal grade of 500 cities before the first mutation, best route map after 15 times of mutation and tendency of optimal grade of the final mutation are displayed with algorithm animation. The optimal grade is about 0.0455266 for the best route map before the first mutation, but is raised to about 0.058241 for the 15 times of mutation. It shows that through the improvements of algorithms and coding methods, the efficiency to solve the traveling problem can be raised with genetic algorithms.

The fuzzy pattern recognition problem is studied by the L-series of formation in the abstract analytic number theory. A method is given to evaluate the model base type of the information granules, which consist of massive data. Additionally,it is used to analyze the relation between process parameters and weld appearance in the welding process.
An Improved Pruning Algorithm for Fuzzy Neural Network
Authors: Ai Fang Ju
Published: September 2013

The number of fuzzy rules directly determines the complexity and efficiency of Fuzzy Neural Network (FNN). The Iterative Pruning (IP) algorithm belongs to the Pruning Method, and it spends much time computing adjusting factors of the remaining weights. So the Improved Iterative Pruning (IIP) algorithm is put forward, which adopts dividing blocks strategy and uses the Generalized Inverse Matrix (GIM) algorithm to replace the Conjugate Gradient Precondition Normal Equation (CGPCNE) algorithm for updating the remaining weights. The IIP algorithm is applied in the rule-reasoning layer of FNN to simplify its rules and structure in a great extent and preserve a good level of accuracy and generalization ability without retraining after pruning. The simulation results demonstrate the effectiveness and the feasibility of the algorithm.

Regional Differences between China's Telecom Industry Development and Economic Growth - an Empirical Study Based on Eastern and Western Panel Data
Authors: Wang Huan , Wang Zeng Min , Xie Qi Ling
Published: September 2013

Through establishing a dynamic panel data model and based on panel data which were calculated at 2000 constant prices from 2000 to 2011 of 23 provinces in the eastern and western China, this paper studies the causal relationship between telecommunications development and economic growth of eastern and western China, using the method of unit root test, the differential method and Granger causality test. The empirical results show that there is a causal relationship from gross regional product to the direction of the telecom business volume in the eastern China, but not in the western. This result means that the improvement of telecommunications infrastructure is not enough to stimulate local economic growth, while the western region's economic growth is not significantly driven by the development of the local telecom industry as well.
