Due to uncertainties in target motion and limited sensing regions of sensors, collaborative target tracking in wireless sensor networks (WSNs) suffers from low tracking accuracy and lack of reliability when a target cannot be detected by a scheduled sensor. Generally, actuating multiple sensors can achieve better tracking performance but with high energy consumption. Tracking accuracy, reliability, and energy consumed are affected by the continuous sensing and transmission and coding method. In this paper, an optimized energy-efficient multisensor scheduling scheme is proposed for collaborative target tracking in WSNs. Simulation results show that, compared with existing scheduling mechanism the proposed scheme can achieve superior energy efficiency and tracking reliability while satisfying the tracking accuracy requirement. It is also robust to the uncertainty of the process noise.

Failure Mode and Effect Analysis (FMEA) is an important method to ensure the effectiveness of manufacturing process, which can prevent the happening of various potential failure. If the knowledge of FMEA can be accumulated and utilized reasonably, the quality management in manufacturing process will get decision support timely, and the efficiency of product quality problem analysis also can be improved. But, it is impossible to integrate the dispersive FMEA knowledge in the manufacturing process because there is a lack of unified management criterion of FMEA knowledge. In order to satisfy the requirement to share, reuse, and maintain FMEA knowledge, the representation method of FMEA knowledge based on ontology is put forward in this study. The structure of FMEA knowledge ontology can be described via visual modeling tool- Unified Modeling Language. In this study, the FMEA repository has been built and the acquisition, storage and searching of FMEA knowledge has been researched to satisfy the need of sharing and reusing of the FMEA knowledge in the manufacturing process.

The notion of 'classes of a path in an Entity-Relationship (ER) data schema' was put forward as a characterization of the capability of a schema of accommodating data instances whereby to provide information for various purposes including answering a query. Thus far though, criteria with which a process of classifying paths can be systematically carried out are yet to be found and formulated. To this end, one possible approach seems to first all accurately and formally describe paths so that we can reason about them, and then to examine the characteristics of the formal representations of the paths with a view to finding useful clues and indications. We propose to use Description Logics (DL) for this task. In this paper, we show how to use Description Logics to formulate paths in an ER schema whereby to find desirable criteria.

After studying the chaotic of economic organization carefully, we get to know the synergetic effect between organizational chaos and organizational innovation. We attempt to utilize the environment inducement to control chaotic change in organizational innovation. In addition, while analyzing the chaos characteristics of economic organization and reasons of organizational innovation, we have introduced the concept of managing entropy, and have done the further explanation to the relation between inside entropy and external entropy by quantization. Finally, this paper establishes the mathematics model during organizational innovation and external environment condition on the basis of Chaos Theory. Through analyzing, we find this model has feasibility in theory.

In this paper,a support vector regression neural network (SVR-NN) approach is presented to assessment the visual quality of JPEG-coded images without reference image.The key features of human visual system (HVS) such as edge amplitude and length, background activity and luminance are extracted from sample images as input vectors. SVR-NN was used to search and approximate the functional relationship between HVS and mean opinion score (MOS). Then,the measuring of visual quality of JPEG-coded images was realized. Experimental results prove that it is easy to initialize the network structure and set parameters of SVR-NN. And the better generalization performance owned by SVR-NN can add the new features of the sample automatically.Compared with other image quality metrics, the experimental results of the proposed metric exhibit much higher correlation with perception character of HVS. And the role of HVS feature in image quality index is fully reflected.
