Vehicle-grade traffic information selecting type based on floating cars plays a significant role when it was under the influence of emergency accidents, and map matching (MM) is the key technology of this type. In this paper, against the problems of current MM method, we proposed a novel MM method based on road incremental updating data. This method was carried out through network topology which updated according to roads' dynamic changes, and it could solve real-time MM process by an effective candidate links identification method, at the same time, the MM method put forward applied parallel roads reverse recognition method on the link matching. And on the junction, this method took delay matching method and optimal path selection method to overcome the MM complexity caused by intersections and main side roads in large-scale urban traffic network. Experiment results showed that the MM method proposed in this paper can perform high MM precision in large-scale and complicated road network under emergency accidents.

To improve the reliability of traditional supervision system for intelligent equipments, a supervision system based on redundant work stations is proposed and then the gateway applied in this system is designed. According characteristic of intelligent equipment communication protocol, the multicast gateway has relatively high performance, which is confirmed by the efficiency comparison of UDP with TCP and the differences among unicasting, multicasting and broadcasting. Experiments results clearly indicate that the multicast gateway can increase packet transport speed and decrease computation of network bandwidth as well as the load on hosts with no interest in the application. The supervision system using this gateway can have improved reliability but has effect on whole performance with might and main.

The color forest dynamic inspection images corrupted by some noise are a large amount of original information obtained in the processing of defending the forest diseases and insect pests. Based on analyzing three color image attributes such as resolution, pixel depth and true color or pseudocolor, it is separately presented what are the external evaluation rules about the means and effect of the forest plant diseases and insect pests color image denoising processing in real time in RGB, HSI and YCbCr color space. The experiment results show that color space must be reasonly selected during the course of color image denoising. The advantage of applying HSI or YCbCr color space is that the denoising arithmetic executes faster and it fits the circumstance of less noise than applying RGB color space. The advantage of applying RGB color space is that the denoising arithmetic executes slower space and it fits the circumstance of more noise than applying HSI or YCbCr color.

It is well known that contours in image are salient when a series of edge elements are aligned in a collinear or co-circular fashion. In this paper, a contour extractor is constructed to extract contours by using the competitive layer mode implemented by Lotka-Volterra recurrent neural networks. This extractor can bind all edge elements which belong to a contour onto a layer. In order to extract long contours, by moving the established contour extractor along a long contour, then the long contour can be extracted segment by segment. Experiments show that the proposed method can extract long contour properly from images.

This paper gives the theoretical method to determine water-coming volume by using pseudo-tracer. According to the flow mechanism of tracer in reservoirs, the theoretical model of numerical simulation of tracer has been established. The method that is implicit to pressure and explicit to saturation for difference solution of model is used and a numerical simulation software has been designed. The calculation method to ascertain the direction and water-coming volume of pseudo-tracer has been given. The water-coming volumes of four injection wells in Xing 4 to 6 blocks of Daqing Oilfield has been calculated and the direction of water-coming has been estimated. The reasons for remaining oil and the potential exploitation measures have been put forward. The results show that the water-coming volume of injection well sj312 is 19.28 m3, which accounts for 43% of the total water volume. This well is the main inflow direction of this block. Therefore, this research can provide theoretical basis for the remaining oil potential of other blocks.

Through automatic repeat request (ARQ) mechanism, additional diversity benefit can be obtained for delay-tolerant wireless networks. In this paper, we combine the distributed selection cooperation protocols with ARQ mechanism to develop more powerful cooperative schemes and analyze their performance from the perspective of diversity-multiplexing-delay (D-M-D) tradeoff. We prove that directly extending the selection cooperation protocol with single round of feedback to multiple rounds does not lead to optimal D-M-D tradeoff. Then we develop an improved scheme achieving the upper bound of D-M-D tradeoff and also propose an efficient scheme that greatly reduces the number of feedbacks and almost achieves the optimal performance. The D-M-D tradeoff analysis and simulation results demonstrate the significant performance improvement of all the proposed schemes.

This paper introduces a voting scheme for safety-related analog input module to arbitrate between the results of redundant channels in fault-tolerant system. The design approach is a distributed system using a sophisticated form of duplication. For each running process, there is a backup process running on a different CPU. The voter is responsible for checkpointing its state to duplex CPUs. In order to increase the dependability for safety-related controllers, the I/O modules use redundancy to reduce the risk associated with relying upon any single component operating flawlessly. The 1oo2D voting principle is commonly used in fault tolerant I/O modules to provide passive redundancy for masking runtime faults at hardware and software levels, respectively. A dual architecture (1oo2D) which provides high safety integrity to a rating of SIL 3 is presented. The outputs from two identical channels operating in parallel with the same inputs are supplied to a voting unit that arbitrates between them to produce an overall output. Based on the hardware logic model and FPGA technique, the study adopts the hardware voter which has much more advantage in the velocity and reliability. Finally, using modelsim simulations, we verify the effectiveness of the proposed voter design in preserving the hazard-free property of the response of an analog inputs module.
