	abstract = {<p>\&nbsp;Firstly, this paper gives a data aggregation algorithm based on learning automata to solve the problem that the existing data aggregation algorithm can{\textquoteright}t solve, the uneven energy cost, and the existing algorithm can{\textquoteright}t change the gathering path dynamically existing the overhead environment. In the proposed method, nodes can change its gathering path to adjust the overhead environment. All the nodes of WSN equipped with a learning automata. These leaning automata learn all the gathering path of the nodes. In the process of transmit information two kinds of data are transmitted, including data packet, knowledge packet .When the information of the nodes changes, according to the feedback of the nods, the learning automata gives the reward or punish to the current gathering path, which help to find the best gathering path. Secondly, this paper improved the wavelet data compression algorithm, which was brought out as the correlation between different data. The algorithm do not reduce much of the data relate to the original data. After the wavelet data compression, Huffman coding compression algorithm will improve the data compression ratio.</p>

The system model and fuzzy PID control algorithm was established by using AMEsim/Simulink joint simulation platform. The step response and Sine tracking performance of the system with PID and fuzzy PID control algorithms was investigated by simulation. At the same time, the performance of PID and fuzzy PID control was studied on the self-developed electro-hydraulic servo control experiment table.

We propose a new approach what we call Augmented Broadcaster Identity-based Broadcast Encryption (ABIBBE).

So in this paper with the data collected by SCADA a leakage monitoring system of pipeline in heating network is designed by the Matble graphical user interface program (GUI). The theoretical basis of this monitoring is the heating network pressure graph theory and the theory of genetic algorithm. With the theory of genetic algorithm the data col-lected by SCADA could be optimized. The optimization avoid the erroneous data which due to measurement error. With the heating network graph theory the leakage monitoring system of pipeline could identify if there is a leakage in the operating conditions in heating pipe network. In the leakage monitoring system, the first step is to collect the initial data which optimized by genetic algorithm as a standard data and these data are stored as a fixed value. After that this system collects the real-time data of heating network and optimizes these data. Finally, the system compares the optimizing real-time data and the fixed value to determine whether there is a leakage. With the experiment the monitoring system which designed in this paper is proved to be very useful in leakage discrimination.},

Conventional fault identifying method could only classify fault into explicit set. Yet, when a novel faulty pattern occurs, the conventional method can not identify this new pattern and will classify it into a set known ahead of time. For the purpose of robustness of fault identifying method, the supervised classification and the unsupervised clustering are integrated together. Faulty features are extracted with wavelet package decomposition to train the supervised classification algorithm and the unsupervised clustering algorithm. As the supervised classification method, Support Vector Machine (SVM) is utilized to classify those faulty patterns known ahead of time into explicit set for the purpose of identifying faulty pattern. As the unsupervised clustering method, subtractive clustering method is utilized to identify the novel fault pattern. Therefore, SVM and subtractive clustering are integrated to identify sensor fault pattern even when novel faulty pattern emerges. The applicability and effectiveness of the proposed method is illustrated by flow sensor data in an engine fuel providing system. The result shows that the method adopted provides better performance compared with conventional method while satisfying the robust requirement of fault identifying method.},

	abstract = {The EP (Enterprise-Participant) data model is a language homomorphic to and semantically equivalent to a class of total recursive functions. It takes a unique position in the fields of programming languages and database management. Mathematically, it enables a programming language to achieve the greatest possible ease of use in software development and maintenance. (This assumes that a programming language incorporated with a higher expressive data model was easier than another one with a lower expressive data model, or no data model at all.) Practically, Froglingo - a programming language incorporated with the EP data model is a monolith that consolidates multiple software components of traditional software architecture. In addition, Froglingo is untyped, i.e., programmers write application programs without a necessity of user-defined types. Finally, Froglingo is a novel approach to many challenges facing traditional technologies, including feature scalability, user interface flexibility, and similarity. In this paper, we show with further clarity the concept of ease of use by proposing a mathematical definition for the concept of data models and by relating Froglingo with other programming language through the analysis of types and higher-order functions.},

	abstract = {The Ubiquitous Computing envisions a world of communicating mobile devices. As mobile devices usually have limited resources, it brings up the challenge to search and invoke services at any time and any place in an accurate, efficient and adaptive way. In this paper, we propose to filter services by matchmaking the precondition of service invocation and the context information of service consumer, in order to increase the accuracy and adaptivity of service discovery and recommendation in mobile environment. We construct context ontology to describe the environment when a service consumer submits service request first. And then, we propose to formalize the precondition of a successful service invocation based on a lightweight DL theory. Finally, reasoning on context satisfiability can be used for service recommendation. A case study shows our approach works well.},

Indeed, the discussion process plays an important social task in collaborative learning practices.

Consequently, tutoring tasks during on-line discussions usually restrict to offer evaluation results of the contributing effort and quality after the collaborative learning activity takes place and thus neglect the essential issue of constantly considering the process of knowledge building while it is still being performed.

Since the code has the maximum d min{\textquoteright}, the robustness of this code is optimal. However, due to the limited availability of the codewords, the performance is restricted. Superior coding and binning methods are derived from the in-depth analysis of the simulation results. Simulation results identify this restriction and solutions are discussed. Comparisons are made with non-orthogonal codes showing the robustness advantage of biorthogonal codes.},

This kind of systems always involves high technical factors and has to spend a large amount of money, so the quality and reliability of the software deserve to be further studied. Hence, we propose to apply four intelligent classification techniques most used in data mining fields, including Bayesian belief networks (BBN), nearest neighbor (NN), rough set (RS) and decision tree (DT), to validate the usefulness of software metrics for risk prediction. Results show that comparing with metrics such as Lines of code (LOC) and Cyclomatic complexity (V(G)) which are traditionally used for risk prediction, Halstead program difficulty (D), Number of executable statements (EXEC) and Halstead program volume (V) are the more effective metrics as risk predictors. By analyzing obtained results we also found that BBN was more effective than the other three methods in risk prediction.},

The paper proposes a knowledge-based approach that employs category theoretic models to formalize and mechanize objectoriented software design and synthesis by focusing concern on reasoning about the interdependency relationships at different levels of abstraction and granularity. The major benefit of our approach is twofold: First, it provides an explicit semantics for formal object-oriented specifications, and therefore enables a high-level of reusability and dynamic adaptability. Second, it utilizes the ability of categorical computations to support automated software composition and refinement. A prototype tool that demonstrates the feasibility and effectiveness of our approach is also presented.},
