In order to make a better performance analysis and reliability evaluation of communication networks, a new definition of Delay-Reliability in communication networks, an algorithm to calculate approximate solutions of the Delay-Reliability in communication networks and a delay failure model in communication networks are presented in this paper. Inspired by the road resistance function in transportation networks, we analyze the similarities and differences between communication networks and transportation networks, and use OPNET simulation to build a new delay failure model in communication networks. Based on probabilistic user equilibrium model and our delay failure model, in stochastic-flow networks, we use discrete random variables to characterize delay in a single link and the link's degraded conditions to propose a new definition of Delay-Reliability in communication networks and its corresponding approximate algorithm. The approximate algorithm is especially useful and practical in large scale backbone network engineering due to its major computational advantage. For illustration, an example is given to show that our definition, algorithm and delay failure model can make a reasonable performance analysis and reliability evaluation of communication networks.

Seat belt detection is one of the important detecting functions and is widely needed in the field of intelligent transportation system. However, research for which is still limited in terms of the increasing requirements at present. In this paper, one algorithm for detecting vehicle seat belts on road is proposed. And according to the method discussed in this paper, a type of feature based on gradient orientation is employed to describe and detect seat belts. After the image pre-processing, the front window location and the human face detecting, this feature is finally extracted in the selected region and the conclusion is given by counting the seat belt feature in the area which close to the right side of the detected human face area. Another approach is also designed in case that the human face detection fails. Tests on high-definition vehicle images show that the proposed algorithm is capable of extracting belt-feature under difference circumstances and is also effective to tell whether the driver has fastened its seat belt.

Wikipedia is the largest online encyclopedia. Its openness allows anyone to edit an article, making articles vary greatly in quality. As only a small proportion of articles are assessed manually, the automatic evaluation of quality has become a highly active research field. Among the factors that affect quality, revision action is the direct factor. In this paper, we conduct a lifecycle analysis of the revision action of featured articles-the best work on Wikipedia, to find out the revision behavior patterns. Using a fine-grained approach, we parse revision actions into insert, delete and replace actions to study their performance in different phases of the lifecycle. Our results reveal that featured articles have distinct revision behavior over different phases. The contribution of the research is to show the correlation between revision behavior and the evolution of quality, which can help us understand what is behind the evolution of articles and can be used to assist quality evaluation.

This paper presents a Web service composition method which supports the associations of services in order to improve the success rate of Web service composition and the quality of the composite service. Firstly, a context-aware web service composition model is built and this paper introduces the concept of service-correlation matrix which means presenting the context of service components in the form of matrix and dynamically updating the matrix with context-awareness technology. Secondly, this paper introduces genetic algorithm into web service composition. Experimental results indicate that the method in this paper effectively reduces the deviation between the theoretical value and the practical value of the context properties of the composite web services which are significantly associated with others.

Even virtual machines has been widely used as the unit to allocate the processor time or storage spaces by the providers of Cloud Computing systems, the energy consumption pattern of virtual machines in Cloud Computing system is not clear enough yet now. In this paper, we built an energy consumption model of the Cloud Computing system, by using statistical method we can estimate the energy consumption of a virtual machine in a small range of errors in 3%-6%. Then, based on the model, we proposed a virtual machine scheduling algorithm to improve the energy efficiency of the system. First, we set a threshold value of energy consumption for each server in the system, and by analyzing these work plans submitted by each virtual machine, we tested whether the threshold will been exceeded or not. Then, by migrate one/several chosen virtual machines to other physical servers in the system we can reduce the energy consumption of the whole system. Our evaluation shows that the proposed scheduling algorithm can effectively implement energy-saving goals without significant decline of the Quality of Services.

In order to solve e-tailing service integrator's goods and logistics service coordination problem, this paper designs a supply chain model which consists of a product supplier, an e-retailer and a logistics service provider. The purpose of this model is to analyze the effectiveness of three types of supply chain contracts within the e-commerce logistics service supply chain. This article will analyze wholesale price contracts, revenue sharing contracts and quantity flexibility contracts. The models under three types of contracts are constructed to analyze the optimal decisions. In addition, the article will explain why managers in the e-commerce industry should adopt these supply chain contract approaches to increase revenues. The models described in the study could be seamlessly utilized by e-retailers and logistics service providers to maximize their revenues and profits. The results show that this model can coordinate the e-commerce logistics service supply chain by adjusting contract parameters and improve the profits of the members.

In this paper, saliency textons model is proposed to encode color, orientation and saliency cue and spatial information as image features for CBIR, where the image representation is so called saliency textons histogram. Experimental results indicate that the performances of saliency textons histogram outperform Gabor filter and multi-text on histogram. The saliency textons histogram can combine color feature, edge feature and spatial layout together. Furthermore, saliency textons model can simulate visual attention mechanism.

Mine hydrogeology conditions are very complex in china, especially in North China type coal mine. When the coal is being mined, it is seriously threatened by Ordovician karst water with high pressure. Water inrush accidents often happen in North China type coal mine which has become an important factor affecting the safety in production of the coal mine. Taking Dong Shan coal mine as an example, the paper analyzed the principle of water-inrush from coal floor of the mine by summarizing the mine water inrush in the coal mine. Early-warning indexes of water inrush which include water temperature, water pressure, stress and strain were built. Structure of prediction system for water-inrush disaster was designed, and the hardware and software of the system were developed. Industrial test for the prediction system was done in 51523 Faces. Practice shows that the prediction system can monitor early-warning indexes of water inrush in real time, and as well to distinguish the mine water inrush risk which can provide the foresight of the information for preventing water inrush disaster.
