Knowledge reduction is a basic issue in knowledge representation and data mining. Although various methods have been developed to reduce the size of classical formal contexts, the reduction of formal fuzzy contexts based on fuzzy lattices remains a difficult problem owing to its complicated derivation operators. To address this problem, we propose a general method of knowledge reduction by reducing attributes and objects in formal fuzzy contexts based on the variable threshold concept lattices. Employing the proposed approaches, we remove attributes and objects which are non-essential to the structure of a variable threshold concept lattice, i.e., with a given threshold level, the concept lattice constructed from a reduced formal context is made identical to that constructed from the original formal context. Discernibility matrices and Boolean functions are, respectively, employed to compute the attribute reducts and object reducts of the formal fuzzy contexts, by which all the attribute reducts and object reducts of the formal fuzzy contexts are determined without changing the structure of the lattice. © 2014 Elsevier B.V.All rights reserved.

QoS-aware binding of composite services provides the capability of binding each service invocation in a composition to a service chosen among a set of functionally equivalent ones to achieve a QoS goal. Hence, service selection approach plays a very important role in service computing. However existing approaches little considered the computation time. In this study, we propose a fast QoSaware web service selection approach. This approach adopts a particle swarm optimization algorithm select the most service with users' QoS requirements Experimental results show that our approach can find best suitable services with lower time cost than other approaches in web service selection. © 2014 ACADEMY PUBLISHER.

The analysis of two-dimensional rotation and impact properties of volleyball serving benefits detailed force analysis during the process of hitting and serving. In this paper, a method combining modeling and actual impact properties analysis is proposed and utilized to analyze two-dimensional rotation curve of volleyball. And the actual serving, sideways position, backhand hit are taken as example to carry out a detailed analysis of the process, and build up the model to reflect the effect of speed, arc, rotation and other factors on the two-dimensional rotation in volleyball serving. The test results show that this method has a good guiding significance for the analysis of the actual volleyball. © (2014) Trans Tech Publications, Switzerland.

A fast parallel algorithm for computing one-dimensional manifold of a hyperbolic fixed point of a map was presented. With the new algorithm, field iteration was taken as a basic idea. The local manifold was subdivided, the curvature constraint and distance control condition were used to implement interation computation. Independently computing map values and checking accuracy were done in each interval to realize parallel computations and control the growth of manifold. The feasibility of manifold parallel computation was proved theoretically. Simulations and test data indicated that the proposed algorithm has a faster computing sped and a better accuracy.

Quality of Service (QoS) has been widely used to support Web Service selection and composition. Thus, QoS is very important for users to select the most suitable Web services. In this paper, we proposed a method to measure QoS of Web services. The key of the approach is to use Bayesian Network to measure each QoS value of Web services. The experimental results show that our proposed method can measure QoS of Web services effectively. © 2013 Springer-Verlag.

An algorithm for computing 2D stable and unstable manifolds of hyperbolic fixed points of discrete dynamical systems is shown. With the fact that Jacobian transports derivative along orbit of an invariant manifold, an algorithm for computing ID manifold is proposed. The mesh point is located with a Prediction-CoiTection scheme which reduces searching time and at the same time gives rise to a simplified accuracy condition. 2D manifold is computed by covering it with orbits of ID sub-manifold. A generalized Foliation condition is used to guarantee that 2D manifold is growing equally along orbits of ID sub-manifold in different directions. Performance of the algorithm is demonstrated with hyper chaotic 3D Henon map and Lorenz system. © 2014 Chinese Nuclear Society.

We present a deep improved particle filtering theory which selects samples from comparison of both weight increasing trend and weight. It decides fission and reproduction of samples through statistic analysis of samples. Though approaches increase computing time for trend judging, computing accuracy is improved.

In this paper, we proposed a web service discovery approach. The approach adopts skyline computing to find the most suitable service for users with low cost.
