Signed network is the network with both positive and negative links. Many real-world complex systems can be represented as signed networks, which are unbalanced according to structural balance theory. Unbalanced degree of signed networks is the distance to exact balance. Evaluating unbalanced degree of signed networks is a NP-hard problem, which has attracted many attentions. Many approaches are developed to compute structural balance. However, the results obtained by these approaches are unsatisfactory. In this study, the computation of unbalanced degree is convert to an optimization problem whose object function is come from the Hamiltonian of Edwards-Anderson spin glass model. We use a new Cultural Algorithm named CA-SNB to solve the optimization problem. The Cultural Algorithm, a new computable framework of Evolution Algorithm, has been successfully applied to many areas. In CA-SNB, the evolution of population space and belief space is based on Genetic Algorithm and greedy strategy respectively. Experiments on social and biological networks show the excellent effectiveness and efficiency of the proposed method.

Data center microenvironment affects the reliable operation of servers and related network equipment, and it will also affect their performance and service life. But as more and more IT and electronic-equipment manufacturers are starting to improve technology, widely used "immersion silver" surface treatment technology in circuit board, which uses silver replace tin-lead alloy, the problems will follow. Because "immersion silver" treated board is easy to be corroded in high sulfur content and a certain humidity air environment. The silver and copper in the circuit board is etched, and derivatives produced gradually spread in the circuit board, which developing to a certain extent will cause electronic short circuit and then cause the device component failure. In order to ensure that the server device has a good operating environment, this article has designed a set of micro environment intelligent monitoring system, which can monitor and control the microenvironment and analyze the server operating environment and put forward relevant measures and suggestions for operational to ensure sustained and healthy operation of the IT systems in the computer room.

Wireless Sensor Networks (WSNs) is one of the hot topics in the field of information, which can be used in the special environment to realize the signal acquisition, processing and transmission. As a key technology of WSNs, time synchronization has achieved a wide range of attention and many scholars have come up with lots of methods to solve the problems for different applications. Among these problems the consistency of multi hop error in large scale networks is one of the key difficulties that need to be further considered. In this paper, a mobile node and many fixed nodes form a mobile wireless network. Furthermore the mobile node is used as the time source. In our method the synchronization process does not depend on any special network topology because fixed nodes directly synchronized to the mobile node that traverse the whole network periodically. For the nodes synchronize to the mobile node directly, the time synchronization of nodes in the network keeps in good consistency. Experiments and analysis suggest that our method has greatly improved the stability and consistency of the time synchronization in compare with the traditional hop by hop synchronization method.

Funneling effect is one severe problem for monitoring wireless sensor networks (WSNs). The introduction of multiple sinks can alleviate the problem of funneling effects. However, the advantage of multiple sinks may not be exploited fully if imbalance of loads exists in the network. This paper studies how to balance the loads for a sensor network with multiple sinks so as to prolong the network life. Motivated by the idea of commercial network, a load-balancing routing approach which especially focuses on balancing the loads of critical nodes is proposed. Simulation results validate the effectiveness of the approach.

In this paper, we propose a semi-supervised learning method to simultaneous segmentation and labeling of parts in 3D garments. The key idea in this work is to analyze 3D garments using semi-supervised learning method which can label parts in various 3D garments. We first develop an objective function based on Conditional Random Field (CRF) model to learn the prior knowledge of garment components from a set of training examples. Then, we exploit an effective training method that utilizes JointBoost classifiers based on the co-analysis for garments. And we modify the JointBoost to automatically cluster the segmented components without requiring manual parameter tuning. The purpose of our method is to relieve the manual segmentation and labeling of components in 3D garment collections. Finally, the experimental results show the performance of our proposed method is effective. © 2015 Binary information Press & Textile Bioengineering and Informatics Society December 2015.
