Energy efficiency has received extensive attention in energy-constrained Wireless Sensor Networks(WSNs). As is known, radio communication accounts for major energy consumption of wireless device and the control of radio transmitter can make effective function with energy efficiency system. In this paper we test and analyse the relationship between precision and synchronization rate and we also give an initial model denote for the relationship among synchronous cycle, time error and energy consumption. The experiments and analysis in the paper show the feasibility of long cycle time synchronization for WSNs under certain limitation and the result will be helpful for the time synchronization method with low energy consumption.

While TRIZ is increasingly developing both in research and education, users always encounter difficulties in their attempts to practice it, especially for one of the most complicated inventive problem solving tools, the Su-Field analysis, which is used to analyze and improve the efficiency of a technical system. Generally, the process of using a Su-Field model to solve a specific inventive problem includes: building a Problem Model, mapping it to a Generic Problem Model, finding a Generic Solution Model based on the corresponding inventive standard and finally establishing and interpreting a Solution Model in real life. As one of the most important phases of the Su-Field analysis, the last step is normally implemented manually with the help of the pointers to physical effects, which link generic technical functions to specific applications and systems. The adequate pointer, compatible with the context of the specific problem, should be chosen to assist the users to instantiate the Solution Model. However, the pointers to physical effects and the specific problems are built at different levels of abstraction, so it is difficult for the users to choose among many eligible pointers to physical effects given a certain function. This paper proposes a heuristic method to use the pointers to physical effects based on ontology reasoning. The use of formal models, called ontologies, allows to formally define the concepts about the models and the effects and to apply logical reasoning on them. An inventive standards ontology and a physical effects ontology are firstly built to describe the process of Su- Field analysis, and then the logical reasoning rules are established according to a lexical dictionary, the analysis of the inventive standards and the physical effects. The lexical dictionary, based on WordNet, is built to improve the selection of the appropriate effect to apply. Finally, ontology reasoning is implemented to provide heuristic physical effects for the users.

While TRIZ is increasingly developing both in research and education, new users always encounter difficulties in their first attempts to practice it. In such situation, Altshuller's original matrix often appears as an "easy-to-begin- with" tool. However, while not being representative of what TRIZ really is, it continues to seduce new users, teachers and trainers. Several approaches to automate the use of the contradiction matrix have been proposed in literature, and researches on the automatic match between specific parameters of the artefact being considered and Altshuller's generalized parameters remains a topic of interest. In this paper, we propose a way to automate the proposal of equivalencies between a specific parameter and a generic parameter from the matrix. This method calculates the semantic distance between short texts, and uses it to fill the semantic gap between the specific parameters of the artefact and the generalized ones. Case-based reasoning is also used to improve the whole accuracy of the method. © 2015 The Authors. Published by Elsevier Ltd.

Short text is a popular text form, which is widely used in real-time network news, short commentary, micro-blog and many other fields. With the development of the application such as QQ, mobile phone text messages and movie websites, the size of data is also becoming larger and larger. Most data is useless for us while other data is significant for us. Therefore, it is necessary for us to extract the useful short text from the big data. However, there are many problems with the short text classification, such as fewer features, irregularity and so on. To solve these problems, we should pretreat the short text set first, and then choose the significant features. This paper use semi-supervised learning method and SVM classifier to improve the traditional methods and it can classify a large number of short texts to mining the useful massage from the short text. The experimental results in this paper also show a good promotion. © 2015 SERSC.

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.
