Aiming at the transmission reliability and storage management of multimedia data, the multimedia big data frame combination storage strategy is proposed based on the virtual space distortion analysis model. On the one hand, the virtual space distortion analysis model is established. This model can be used to find the high similarity of video frames and flow structures in different multimedia streams. The model can be used to uniform the multimedia stream state and effectively improve the efficiency of data mining. The model can effectively analyze the difference between the multimedia stream of virtual space and the storage of the server group. On the other hand, based on the distorted efforts of the virtual space and heterogeneous of the multimedia data stream, combined with big data multimedia service requirements, the big data frame combination of storage space and virtual space integration would be integrated as a whole through the multimedia data frame combination and distorted perception. Finally, the combination of multimedia data frames is proposed. The delay, channel, storage and big data processing level of the virtual space storage scheme and were analyzed and evaluated by the simulation experiment, compared with the physical storage scheme of the multimedia big data. The experimental results show that the proposed scheme has significant advantages in the above aspects.

This investigation presents a ZigBee and Sip based smart home system (ZSS) that automates home-service operations and remote access. The ZSS home system comprises five subsystems, namely home automation network, home IP network, home gateway, remote access unit, and cloud service unit. The home automation network is a wireless sensor network, responsible to sample sensors data and control actuators by ZigBee instructions. Security system adopts IP network technology to transmit videos from IP cameras to remote units. A home gateway middleware is designed to extract atomic service provided by a single device, and then customize service rules which can meet variable user demands. Peer to Peer transparent data channels between remote mobile phones and home devices are set up by Sip framework to overcome connection issues due to network address translation and dynamic public IP address. A novel data stream algorithm named GCOKDE is exploited to get probability density distribution of environmental parameters which can be used for the condition value of service rule. At the end, this study constructs a prototype to reveal the procedure of realization.

The accurate and reliable statistics are the foundation to grasp the operation of the economy and make scientific decisions. This paper is on the basis of the characteristics of the change of the time series data itself, combined with the characteristics of the grey forecasting model, regression combined model and the double exponential smoothing model, build the combined forecasting model based on the minimum error absolute value sum. Prediction is made on GDP data by the application of the model, and the prediction value obtained represents the "True value", and then from the angle of the abnormal value to analyze the accuracy of the GDP data of China, and the results show that the combined forecasting model is of relatively high practical value in the accuracy test of statistical data, and is worth further study.

This paper studies the moving-target detection and tracking in video serials, RFID information acquisition and multi-source information fusion technologies. And then designs a multi-source information collection and retrieval system, named MSICR, which can detect and track many types of moving targets based on video and RF inputs. Experimental results show that the above system can detect moving targets in real-time video serials, and present information retrieval with high accuracy.

The authors studied the innovative applications of the inductively coupled plasma-atomic emission spectrometry in automotive hydraulic power steering system fault diagnosis. After having determined Fe, Cu and Al content in the four groups of Buick Regal 2.4 main metal power-steering fluid whose travel course was respectively 2~9 thousand kilometers, 11~18 thousand kilometers, 22~29 thousandkilometers, and 31~40 thousand kilometers, and the database of primary metal content in the Buick Regal 2.4 different mileage power-steering fluid was established. The research discovered that the main metal content increased with increasing mileage and its normal level is between the two trend lines. Determination of the power-steering fluid main metal content and comparison with its database value can not only judge the wear condition of the automotive hydraulic power steering system and maintain timely to avoid the traffic accident, but also help the automobile detection and maintenance personnel to diagnose failure reasons without disintegration. This reduced vehicle maintenance costs, and improved service quality.

With the continuous demand for better quality and larger display devices in scientific visualization, virtual reality requirements etc, the limited resolution of single display devices becomes an important bottleneck in improving PC-based rendering system. This paper presents a multi-pc parallel rendering approach under Fast Ethernet environments, which partitions the virtual view frustum and implements frame synchronization of multi-pass parallel rendering based on the sync pulse signals. Test results show that the new approach can maintain state consistency and output integrity of the system, and significantly reduces the parallel network traffic consumption.

Real-time human tracking from a video sequence is a challenging problem due to the coupling of noise, occlusion, and shadow. In this paper, we present an improved frame difference method for accurately human detection and tracking. A novel algorithm that combines different clues to achieve adaptive thresholds is proposed, where a voting-like scheme robust to contours is employed in optimization. Detailed experiments compare our approach to several classical ones, and the results indicate that our approach is capable of obtaining better tracking effects even under conditions of significant noise.

Digital and informationized city information network construction can not only be convenient for providing scientific, intelligent and decision-oriented city, but also offer new path to urban macro control and regulation construction. However, intelligent city marks the foundation for city information network construction, and its development speed is far higher than that of digital city. Therefore, it is not only quite significant but also necessary to research city information network construction from the angle of intelligent city. Through discussing intelligent city as well as urban information network, the topic puts forward opinions on realizing city information network construction as well as key technology of implementation in the perspective of intelligent city.

The problem of evaluating the software quality with intuitionistic fuzzy information is the multiple attribute group decision making (MAGDM) problems. In this paper, we investigate the multiple attribute group decision making (MAGDM) problems for evaluating the software quality with intuitionistic fuzzy information. We utilize the intuitionistic fuzzy weighted average (IFWA) and intuitionistic fuzzy hybrid aggregation (IFHA) operators to aggregate and get the overall value of the alternatives, then rank the alternatives and select the most desirable one(s) according to the score function and accuracy function. Finally an illustrative example for evaluating the software quality with intuitionistic fuzzy information has been given to show the developed approach and to demonstrate its feasibility and practicality.
