The Traveling Salesman Problem (TSP) belongs to the class of NP-hard optimization problems. Its solving procedure is complicated, especially for large scale problems. In order to solve the large scale TSPs efficiently, this paper presents a bilevel genetic algorithm with clustering (BLGAC). BLGA-C uses a clustering method to divide a large scale TSP into several subproblems, each subproblem corresponds to a cluster. K-Means clustering method is adopted in this paper. In the lower level, a genetic algorithm is used to find the shortest hamiltonian cycle for each cluster. All these clusters can be handled parallelly. Then, we need to select two nearest vertices between two clusters, and determine which edges will be deleted from the shortest hamiltonian cycle for each cluster, and which edges will be linked for combining two adjacent clusters into one. Repeat this procedure until all clusters are joined into one whole tour. Different combing sequences among clusters will result in different travelling tours, searching for the shortest is our purpose. Therefore, in the higher level, a modified genetic algorithm is designed for integral optimization with the objective of shortest the whole traveling tour. At last in this paper, we trial run a set of experiments on benchmark instances for testing the performance of the proposed BLGAC. Experimental results demonstrate its effective and efficient performance. © 2016 IEEE.

Association rules mining algorithm based on Rough Set theory is put forward using the idea of Rough Set theory, which applies the improved Apriori algorithm in association rules mining on the basis of Decision Table. The advantage of this method lies in three aspects, including the elimination of redundancy attributes, reducing the number of attributes, while scanning Decision Table just once can produce decision attribute sets. Application example analysis shows that this is an effective and fast data mining method. © 2012 IEEE.

Network virtualization can effectively establish dedicated virtual networks to implement various network ***,the existing research works have some shortcomings,for example,although computing resource properties of individual nodes are considered,node storage properties and the network topology properties are usually ignored in Virtual Network(VN)modelling,which leads to the inaccurate measurement of node availability and *** addition,most static virtual network mapping methods allocate fixed resources to users during the entire life cycle,and the users’actual resource requirements vary with the workload,which results in resource allocation *** on the above analysis,in this paper,we propose a dynamic resource sharing virtual network mapping algorithm named NMA-PRS-VNE,first,we construct a new,more realistic network framework in which the properties of nodes include computing resources,storage resources and topology *** the node mapping process,three properties of the node are used to measure its mapping ***,we consider the resources of adjacent nodes and links instead of the traditional method of measuring the availability and priority of nodes by considering only the resource properties,so as to more accurately select the physical mapping nodes that meet the constraints and conditions and improve the success rate of subsequent link ***,we divide the resource requirements of Virtual Network Requests(VNRs)into basic subrequirements and variable sub-variable requirements to complete dynamic resource *** former represents monopolizing resource requirements by the VNRs,while the latter represents shared resources by many VNRs with the probability of occupying resources,where we keep a balance between resource sharing and collision among users by calculating the collision *** results show that the proposed NMAPRS-VNE can increase the average acceptance rate and network revenu

Authentication is the most basic prerequisite for secure communications. Authentication theory and technology play a key role in the application of modern cryptography. Cross-domain authentication among entities of different management domains is an important subject. An in-depth study on this subject and related supporting theory has been made so far. This paper-outlines the status quo and trends of cross-domain authentication, including the study on the cross-domain authentication mechanism and the framework, the security models, the application protocols, key agreement protocols based on groups, key agreement protocols based on password, provable secure cross-domain signcryption and KEM/DEM key encapsulation. Furthermore, it points out problems which should be widely concerned in the future, and gives the view points for the trends of the research field. © 2012 IEEE.

This paper proposes a new program on the integrity of the data to the probabilistic methods when the number of documents inserted the pseudo-tuple becomes large. In this program, pseudo-tuple inserted in accordance with different particle size were signed. And a user constructs a new type of data structure. In order to ensure normal conversation between the user and the cloud at the same time, this paper uses a challenge-response mechanism. Then a user uses this new data structure to verify its integrity in the client. © Springer Science+Business Media Dordrecht 2014.

Currently, industrial and scientific community are concerned about Service-Oriented Computing (SOC), whose key technology is Web services. Web service is a new distributed computing model. It has a broad prospect in application because of its loose coupling, platform irrelevance, language neutral, reusability and openness characteristics. However, the existing problems of Web service restrict the development of Service-Oriented Computing. The significance of research on Web service access control security model is profound. This paper puts trust mechanism as independent attributes to be used in Service-Oriented Computing security model to solve the above problems, and to be suited for Web services in characteristic of dynamic and fine-grained. © 2013 Springer Science+Business Media.

In this paper, we analyze the characteristics of an acupoint-disease network by using complex networks theory. Firstly, we build an acupoint-disease network using the data from traditional Chinese medicine acupuncture books, and draw the diagram of the acupoint-disease network. Secondly, we make a projection from the acupoint-disease network to a disease-based acupoint network and an acupoint-based disease network respectively. And the static characteristics of these two networks, which include clustering coefficient, average path length and small-world character etc, are analyzed. Finally, we compare the analyzed results above with the traditional Chinese medicine theory, which indicates that the results totally conform to traditional Chinese medicine theory. © 2011 IEEE.

CSTR (Continuous Stirred Tank Reactor) is commonly used in case of immobilized enzyme or immobilized cells. Mathematical model is a useful tool in reactor design, operation condition optimization, and production process automation. Transfer function relates the output and the input and reflects the dynamics of the system. Laplace transforming can make the differential equations into algebra equations, simplifies the solution of the model. In addition, transfer function is simple, easy to use, and able to predict the outputs of various inputs without modification of the transfer function. In this paper, the transfer function for CSTR with immobilized biocatalysts is built as an example for transfer function building and system dynamics analysis. © 2012 IEEE.
