摘要：
A novel image retrieval method using color-spatial histograms is presented in this paper. The new method contains three phases. First, we quantize the color space by Gaussian mixture model. Second, the color-spatial histograms generated for both the query image and the images in the database based on the quantized color components and the improved spatiogram method. Finally, using color-spatial histogram as features, we compare the query image with images in the database by Jensen-Shannon divergence. Our proposed method's availability is demonstrated by the experimental assessment on the COREL image database.

摘要：
Satisfiability problem (SAT) is one of classical combinational problems, which is proved to be a famous NP-complete problem [1]. SAT is widely used [2], [3]. At present, research on algorithm of SAT has made significant progress [4], [5]. Among these algorithms, some are non polynomial even though they can obtain exact solution of SAT; and heuristic algorithm cannot obtain exact solution of SAT, even though it is polynomial. Therefore, it is essential to find an exact algorithm of SAT which is more practical and can effectively the control calculation time.
摘要：
With the development of Internent, the amount of information on the Internet is huge and updated quickly, which makes public opinion monitoring face enormous challeges in dealing with huge amounts of information and complex data. In the age of cloud computing, these data hids the huge value, which includes scienfitic computing, public information and enterprise applications field and so on. For getting some valued information from these data, we need to monitor these network opinion information. However, there are some shortages in traditional Internet opinion monitoring method, such as lack of powerful ability of data collecting and analysis ability. For solving this problem, a cloud computing framework of Internet opinion monitoring is proposed. The specific method is to make use of the mass data process ability of MapReduce to implement a new network information abtaining method.

摘要：
This article describes a mathematical method to distinguish computer graphics (CG) from photographic images (PG). Because white balance, CFA and PRNU noise artifacts are the intrinsic properties of optical imaging, we can use these artifacts to reflect camera imaging-specific to some extent. During experiment, we design a 135-D feature set and perform distinguishing process to capture these artifacts. Images selected from relative Columbia University image database are chosen as our experiment database. Experiment result indicates our mathematical method is capable to identify computer generated images from camera produced images with 95.43 % accuracy.

摘要：
Evaluation and performance analysis of an online collaborative project are never easy tasks because the massive human involvement and other qualitative factors are hard to assess. To figure out the relationship between human related factors and quality of collaboration outcomes, we propose an effective formal approach to estimate the human involvement in collaboration process and testify our method on 100 articles extracted from Wikipedia and Scholarpedia, the qualities of whose historical contents have been evaluated manually by volunteers of specific background. Through comparison of the human involvement and the outcome quality in these two projects, we find that the quality of collaborative products is positively related with the number, dedication and experience of collaboration participants, among which experience decides the necessary amount of human resources for a high quality, and increasing number or dedication of participants can also make up to the lack of experiences.

The canvas in the HTML5 provides very powerful ability to realize complex graphics and image operations. It can be used for developing information application about graphics such as chart module, scientific computing visualization, drawing software, animation system and information visualization and so on. It will play an important role in the web game for PC or mobile platform because the HTML5 has the platform-independent feature. In this paper a system of graphics algorithm presentation is provided and it uses the prototype object and image data structure of canvas rendering context 2D model to define the custom function to implement the graphics algorithm. It demonstrates the realization process of the principle of graphics algorithms and it shows that the canvas has great flexibility and scalability characteristics.
摘要：
Web services are the new paradigm for distributed computing. A critical factor to the overall utility of Web services is a scalable, flexible and robust discovery mechanism. Currently Web Service systems, which publish WSDL-described Web Services in UDDI, cannot support automatic Web Service publication, discovery and execution. Traditional centralized indexing scheme can't scale well with a large distributed system. In this paper, we present a service discovery model for building dynamic, scalable, decentralized registries with flexible search capabilities, to support Web service discovery. In our work, we focus on a fully distributed architecture motivated by recent advances in a two-layer P2P network topology without a need for centralized service registries. Furthermore, the OWL-S ontology is used to add semantics to the Web Service descriptions and then register them on a specific registries peer in the P2P environment according to the service's domain ontology. The experiments show that the discovery model has good scalability and the semantic annotation can notably improve discovery exactness. The improved algorithms can discover the most potential service against request.

摘要：
In urban transit network inquiry system, the optimal scheme of bus line having excessive transfers requires us to consider limiting the number of transfers when to compute the optimal scheme of bus line [1], which can come down to shortest path problem limiting the number of intermediate vertex. And support system of QoS (Quality-of-Service) is playing a more and more important role in communication network. QoS routing problem [2] is to choose transmission path meeting the requirements of QoS service to hop counts, bandwidth, latency, packet loss rate etc. and ensuring effective use of global network resources, which can come down to multi-constrained shortest path problem limiting the number of intermediate vertex. Shortest path problem limiting the number of intermediate vertex is shortest path problem with k-intermediate vertex constraints.
摘要：
This paper presents an electrocardiographic signal classification method. This method first uses a revised locally linear embedding (LLE) algorithm to perform dimension reduction to the Electrocardiography (ECG) data. This manifold distance measurement-based LLE was proposed to solve the defect of conventional LLE that, due to the use of Euclidean distance, it could not properly measure the distance between high-dimensional samples. Using this revised LLE algorithm for the dimension reduction of data, more original data information could be retained, and the features of high-dimensional ECG data could be more effectively extracted, thereby improving the classification accuracy. The method then adopts kernel-based fuzzy C-means clustering algorithm to perform ECG signal classification. Classification tests on four common types of ECG signals-from the MIT-BIN database showed that the proposed method reached an overall accuracy of 99%.

摘要：
A virtual machine placement strategy based on the trade-off between energy consumption and SLA is presented. Aiming at dynamical changes of workload requirements, a self-adaptive placement strategy RLWR based on robust local weight regression is presented, which could decide the overload time of hosts dynamically. After detecting overloaded hosts, one virtual machine migration selection algorithm MNM is proposed. The MNM's objective is to get minimal migration number. The migrated virtual machines are deployed using bin-packing algorithm PBFDH. The experimental results show that our algorithm has obvious advantages than other algorithms.
摘要：
AOP(Aspect Oriented Programming) is a programming technology that makes the OOP (Object Oriented Programming) technology more complementary and perfect when being applied together with OOP technology. AOP provides ideal modularized structure for programming. At the moment, AOP has been supported and applied in two leading programming platforms: Java and .Net. Java provides perfect support to AOP, but .Net has not clearly provided the technique to support AOP. Meanwhile, Design Pattern has been widely used in programming. This study analyzes the theory of AOP technique and provides an implementation strategy for AOP based techniques on Proxy Pattern in .Net platform.

摘要：
Currently, various mobile intelligent terminals have penetrated into our daily life. But at the same time, security and privacy issues of mobile intelligent terminals become a serious problem. In this paper, we present an approach to ensure the secure communication between mobile intelligent terminals. Our idea is to restrict that plaintext information can only exist inside mobile intelligent terminals, and any information outside of mobile intelligent terminals must be automatically encrypted. Experimental results show that our approach is efficient, and incur only 2%similar to 3% performance losses.
