    Finite element analysis has been used to investigate the vibration modal of 480 crankshaft and the stress analysis of crankpin. The aim of the modal analysis was to explain the relationship between the frequency and the vibration modal. And the aim of the stress analysis of crankpin was to find the maximum deformation and maximum stress point. In this paper, three-dimension models of 480 diesel engine crankshaft and crankpin were created through Pro/ENGINEER software. The finite element analysis (FEM) software ANSYS was used to analysis the vibration modal and the distortion and stress status of the crankpin. The results of crankshaft vibration modal were calculated. And the stress figures of 480 diesel engine crankpin were calculated, combined with maximum stress point and the dangerous area. The results would provide valuable theoretical foundation for the optimization and improvement of engine design. View full abstract»

    In this paper, a target localization method based on color recognition and connected component analysis is presented. The raw image is converted to HSI color space through a lookup table, followed by a line-by-line scan to find all the connected domains. By checking the size of each domain, most pseudo targets can be omitted and, meanwhile, the target position would be calculated. Owing to the absence of extra filtering process, the real-time performance of the whole system is greatly improved. Experiments on our ARM system demonstrate that the robot could trace multiple targets under a mean frame rate of 15FPS, including decoding process, which satisfies the requirement of real-time video processing on auto-mobile robot systems.

    Anycast is a mechanism that the source node sends the data groups to the nearest sink node. The paper proposes a communication model of implementing an Anycast service for deploying several sinks in wireless sensor network. We propose a novel anycast tree-based approach to reduce the mutual interference and minimize the energy consumption. Here the nodes as the anycast node form a tree with a sink node as the root, while the height of the tree is based on the distance of the member nodes to the sink node and the residual energy of node. This paper discusses and analyzes the model deeply. The experimental data proves its validity and efficiency. Computer simulation shows that the proposed scheme reduces and balances the energy consumption among the nodes effectively, so it significantly extends the network lifetime compared to the existing schemes.

    To satisfy individual requirements of customers, mobile phone service industries are offering a variety of service modules for customers to build their own customized service packages. In this paper,we present an approach of customizing service bundles using CSP (Constraint Satisfaction Problem), a well-known problem-solving technology in AI domain. Firstly, service customization model containing service elements and rules is represented in a graphical way. Next, the service customization model is transformed as a CSP such that classical constraint solver (such as Choco) can be employed to infer a service configuration. A case of mobile phone service customization in China Mobile is used throughout this paper to demonstrate the effectiveness of the presented approach. View full abstract»

    Image authentication is an important technology to protect images from being malicious tampered and have became an indispensable part of digital world. The main schemes used for image authentication are signature and watermarking in the last decade. However, in traditional serial manners, the operations of both methods are time-consuming, and limit the wide use of image authentication. In this paper, we proposed a CUDA-based implementation of image authentication algorithm with NVIDIA's Tesla C1060. Comparing with the original implementation in CPU, our CUDA-based implementation works 19-36 times faster. View full abstract»

    Ontology construction can allow users or agents of software to arrive at consistent views about organization structure of information, even improve the reusability in the professional fields. However, because of the differences between domains, there is no existing technical route as the standard method for ontology construction at the present time. This paper offers an improved ontology construction method MADRE. This method uses graphic language to explicit represent domain knowledge for research domain. Moreover, it verifies correctness of ontology construction on relation and hierarchy in the phase of ontology evaluation. By applying domain ontology to healthy housing field, it solves the problems of computer applications on healthy housing, such as lack of semantic expression and understanding of expert knowledge. Meanwhile, it realizes the semantic standardization of computer applications in this field. View full abstract»

    Service is provided by a lot of autonomous, heterogeneous devices in pervasive computing environment. Service discovery by interface or key words is not fit for heterogeneity and autonomy of devices in pervasive computing environment. Thereby, service discovery by the way of semantics is a hotspot for research. This paper introduces the service description language, OWL-S, and then designs a prototype of system for service discovery in pervasive computing. The system adopts Three-layer Pervasive Semantic Service Matching Algorithm (TPSSMA) which matches service according to category of service, Input/Output parameters and QoS, and which was proved that it is good for lots of service matching in pervasive computing. In this way, user-specified preferences for web services in terms of non-functional requirements (e.g., QoS) can be incorporated into the web service discovery mechanism to generate a partially ordered list of services that meet user-specified functional requirements.

    A fuzzy-neural network sliding mode control (FNNSMC) is proposed for the attitude stabilization of flexible spacecraft during large angle slew maneuver. The dynamic model of the spacecraft with flexible appendages is derived by Lagrange equation. To make the system state reach sliding mode surface in finite time, a sliding mode controller is designed, so the system is robustness against uncertainties and disturbances during the sliding phase. A fuzzy-neural network system is used to approximate the strong coupling nonlinear dynamics between rigid hub and flexible appendages, so that the elastic vibration of flexible spacecraft during maneuver is suppressed and the attitude of flexible spacecraft is stabilized. Simulation results show that not only high-precision attitude stabilization of flexible spacecraft is achieved, but also the elastic vibration of flexible spacecraft during maneuver is suppressed effectively.
