Currently, with the rapid development of information technology mobile Internet networks quality-of-service (QoS) is confronted with many challenges, especially for telecommunications industry. In the Telecom Service Commitment, customer satisfaction has become an essential index. In this paper, the mobile network QoS of data service indices system is constructed based on the CSI model, it not only considers the customer satisfaction, but also the technical specifications. Finally, we used the theory of fuzzy mathematics to evaluate mobile network QoS. The result shows that this method is reasonable and feasible.

A broadband YIG tuned oscillator (YTO) frequency sweeping signal generator based on the DDS-PLL method is introduced. A linear sweep frequency sinusoidal signal generated by DDS is used to a reference signal of the YTO PLL (Phase-Locked Loop), and the other input of PLL is the linear frequency sweep signal of the YTO, the resulting error correction signal drives the YTO FM coil. Error correction signal can compensate the YTO nonlinear error, thereby ensuring that the YTO sweep signal generator output is accurate, linear frequency sweep signal. The signal generator module has been successfully applied to a spectrum analyzer.

Against the problem of extracting the color aberration of high-reflect-rate ceramic tile surface texture, author came up a way of using wavelet transformation to extract the image texture features. Basically, the way is suggesting using two dimension wavelet decomposition on each passage of the image and extract energy characteristic from each detailed sub-graph. This energy signal merges the message of color and feature. Calculate samples' color histogram statistics as the critical data for doing classification. In the end, using Minimum Distance Classifier to sort the samples. According to the experiment, compare the existing method which mostly using the color histogram distribution, this method can show better message of color distribution in space. Experiment shows that this method can get a better classify result.

In Zigbee network performance evaluation, there is artificiality to determine weights of Multi-dimensional indexes, and the indexes could not be completely independent. We combine the entropy method and correlation between indexes, and build multi-evaluation index weight decision analysis model to get more objective and realistic evaluation of indexes. Using opnet network simulation software, we collect different network performance parameters by changing the node size. The data analysis shows that the entropy can objectively and accurately reflect the size of information provided by each index, and this method can reflect the relative importance of each index more objectively and accurately.

In this paper, we analyzed security and privacy problems of the current low-cost RFID system, and proposed a new RFID authentication protocol based on security policy. This protocol used these methods like setting tag information permissions according to fields and assigning tags with different privacy levels to prevent the authorized tag`s unauthorized information leakage and protected the user's privacy more effectively. Selective one-way/two-way authentication and interested in information transfer mechanism, which can reduce the communication capacity in the whole process of protocol significantly, enable the certification process more flexible, more specific privacy protection, At the same time, tag can reduce the tag hardware requirements by using XOR operation measures which. The security and energy consumption analysis in this paper proved that this protocol can not only protect the authorized tag`s unauthorized information security more flexible, but also reduce the system hardware requirements and communication volume. Compared with the traditional security authentication protocols, this new protocol is more suitable for low-cost RFID system.

In present industrial field, the high-speed data acquisition system with small size, high-accuracy and multi-gain choices is badly needed. This paper presents a realizing solution of a parallel PCI high-speed data acquisition system for universal multi-channel based on the SOPC. With this system, we can either use these 12 channels together or choose combination. Meanwhile, the gain-programmed amplifier can also be selected as well as difference or single-ended parallel input way. Also, the sampling rate of the multi-channel can reach at the same time up to 200KSa/s, and the vertical resolution of the high-accuracy PCI data acquisition module is 16bit.

The hybrid wireless-optical broadband access network (WOBAN) is a novel promising hybrid access network. We can improve its performance effectively by improving the wireless network routing algorithm of it. This paper proposes a novel routing algorithm -- the minimum delay routing algorithm (MDRA). In the algorithm, A time delay estimation method is combined with the Dijkstra algorithm used in the routing algorithm for front-end wireless Mesh network (WMN) of WOBAN. Simulation results show that the delay and TDR performances of MDRA are better than that of the minimum hop algorithm (MHRA) in high load conditions in WOBAN.

Hypersonic vehicle's nonlinear dynamics system is highly nonlinear, multivariable coupled and includes uncertain parameters. To solve this problem, a new back stepping controller is designed based on nonlinear disturbance observer (NDO). The NDO is used to observe the disturbance of the system and the limitation of the disturbance can be unknown. Theoretical analysis is done to validate that the system satisfy control requirements and is uniformly ultimately bounded. The simulation results also show that the developed method is effective and deals with the problem of uncertain factors preferably.

Standard extended Kalman filtering algorithm usually needs a little precise initial value, but Strap down inertial navigation system(SINS) coarse alignment precision for marching vehicle can't meet the requirement. So UKF (unscented kalman filter) was proposed to achieve SINS initial alignment for marching vehicle with odometer aiding. The state equation for large misalignment error model was expounded, and observation equation was derived when the measurement variable was chosen as difference of velocity offered by SINS and velocity reckoned by odometer. UKF filtering algorithm based on additive noise model was derived. Simulation based on vehicular tests data showed that UKF filtering algorithm could achieve SINS initial alignment for marching vehicle, and UKF filtering algorithm could achieve better robustness from filtering initial value, higher alignment precision and faster convergence velocity than Standard extended Kalman filtering algorithm.
