Traditional Complex Event systems (CEP) did not consider the computation requirements of continuous dynamic behavior such as differential equations. In addition, the event composition rules were predefined before the CEP engine began working. The rule defining task is error-prone and cumbersome. In this paper, therefore, a hybrid complex event service is proposed, which deals with not only discrete...
In order to evaluate the real stock value of second board market enterprises in China, this paper try to build a effective model for measuring them. The model which we build were based on the EVA evolution model and enterprises life cycle theories. We choose a real high technology corporation to test our net present EVA model, and find that the real value of the corporation which computed by our model...
With the increasing number of functionally similar services deployed over the Internet, QoS (Quality of Service) plays a more and more important role on deciding which component services should be selected to satisfy the quality requirements for a composite service. Although there exist some service composition approaches to select component services with regard to global QoS constraints, none of...
This article proposed a nonparametric test method by using Gaussian mixture model application idea for reference to evaluating the construction of index architecture. First use Gaussian mixture model to cluster analysis the index architecture. Second use rank correlation coefficient of nonparametric test method to select index architecture. Then determined the evaluate index architecture and guarantee...
A novel multi-loop nonlinear Internal Model Control (IMC) strategy is developed for MIMO systems under the Partial Least Squares (PLS) framework, which automatically decomposes the MIMO process into several univariate systems in the latent space. The ARX-neural network (ARX-NN) model is incorporated in the PLS subspace and identified via optimizing two parameter sets so that the plant-model mismatch...
Based on the generalized accumulated generating operation, this paper presents a new grey model, GAGM (1, 1), for the non-equidistant sequence with jump trend and multi-stage. According to the traditional GM (1, 1), the parameter identification of GAGM (1, 1) is introduced. The particle swarm optimization algorithm is used to solve the parameters. At last modeling with the production of gas well shows...
Based on the concept of open complex system, the paper analyzes three causes of system complexity: system structure, combination exploding and human intervention. And then the paper pointes out that "un-repeatability" is a core characteristic of complex giant system (CGS). Applying the system dynamics to complexity research, the paper constructes a theoretic framework for studying the large...
A novel graphical model based on inhomogeneous Markov random field and Dirichlet process mixture is proposed to address the problems encountered by hidden Markov random field. It incorporates the local and global scale information. A sampling method is also devised based on Gibbs sampler. The model is investigated in the context of image segmentation and the performance is evaluated.
