The key point of the network control systems is that conventional generalized predictive control algorithm cannot deal with random delays, packet losses and vacant sampling. In this paper, the time-stamped multivariable generalized predictive control (TSMGPC) was proposed to deal with this problem. The TSMGPC used time-stamped to calculate the real delay, and the least mean square (LMS) algorithm to estimate the induced delay. In order to reduce the transmission times between the controller and the actuator, a threshold that was set in advance would be used to decide whether the control information were sent to the actuator or not. The simulation results show that the TSMGPC can trace the desired output precisely.

In this paper we propose a new iterative algorithm for the solution of a certain class of double obstacle problems. Such problems arise in the modeling of a variety of physical phenomena and usually involve the determination of an unknown free boundary. Here we describe a way of locating the free boundary directly and provide a proof that the algorithm converges when used with analytic methods. The advantage of this algorithm is that it can be used in conjunction with any numerical method with minimal development of extra code.

A revised strategy particle swarm optimization algorithm is proposed to solve the economic dispatch problems in power systems. Many constraints such as ramp rate limits and prohibited zones are taken into account, and the loss is also calculated. On the basis of strategy particle swarm optimization algorithm, a new revised strategy is provided to handle the constraints and make sure the particles to satisfy the constraints. The strategy can guarantee the particles to search in or around the feasible solutions area combined with penalty functions. The various load demand and various reserve demand by payment for reserve allocated is also discussed in this paper.

As we all know, the content-based image retrieval (CBIR) is very time-consuming due to the extraction and matching of high dimensional and complex features. The traditional CBIR systems could not respond to a very large number of retrieval requests at mean time, which are submitted from the Internet. In this paper, we propose a content-based parallel image retrieval system to achieve high responding ability. Our system is developed on cluster architectures. It has several retrieval servers to supply the service of content-based image retrieval. Our system adopts the Browser/Server (B/S) mode. The users could visit our system though web pages. Our system uses the Symmetrical Color-Spatial Features (SCSF)[25] to represent the content of an image. The SCSF is effective and efficient for image matching because it is independent of image distortion such as rotation and flip as well as it increases the matching accuracy. The SCSF was organized by M-tree[16], which could speedup the searching procedure. Our experiments show that the image matching is quickly and efficiently with the use of SCSF. And with the support of several retrieval servers, the system could respond to many users at mean time. (Abstract)

The wireless monitoring and control of the terminal node by the host computer is realized through a combination of wireless and wired mode. Because there are more measuring points in the barn, 1-wire technology is used to save connection and simplifies the system. In line with the principle of saving the hardware, the system uses powerful STC micro-controller, takes micro-controller and wireless module as the core, achieving the measurement of temperature and humidity. The circuit of temperature, humidity sensor, and RF module is designed, the software of wireless communication is designed.

In cloud computing, cloud user's sensitive data is in the control of a third part, which will lead to considerable risk on the privacy and security of the data. To address this problem we propose a trusted cloud computing platform with sealed storage ability (TSSC). TSSC enable Infrastructure as a Service provider (IaaS) such as Amazon EC2 to provide remote attestation to the IaaS user by an attestation delegation server and seal the IaaS user's sensitive data with their desired integrity of the IaaS configuration. We implement our solution on Xen, and present a simple prototype based Nimbus. Our evaluation results show that the performance overhead of the solution is acceptable.
