Abstract: MARK tag is a common method in industrial image location. In allusion to the disadvantages of conventional MARK located, such as large numbers of templates training set,no scale and rotation ,harsh conditions and slow processing speed ,a improved matching strategy based on NCC is proposed in this paper. The method search and correct the sole MARK in the template, extract 25 grids normalized feature sequence. Then matching with all contour feature sequences extracted in the target image and finally locate the target MARK. The experiment results show that , the method has much robustness to scale and rotation and can meet the real-time processing requirements

Abstract: When tracking a moving human target,the traditional particle filter algorithm based on color characteristic can't get accurate results in situations like complicated background or frequent brightness change.Due to the problem, this paper put forward a particle filter algorithm based on combination of color characteristics and shape features of the target.Firstly, fusing the above-mentioned two features into the particle filter frame to calculate the particle weights and achieve the human tracking goal through image sequences . The experimental results show that the algorithm can improve the traditional tracking algorithms based on single color feature limitations.And greatly improves the accuracy and effectiveness of the human tracking under complex background

Abstract: The paper introduces a device linkage system on firewall between the network side and the switch side of user host, and introduces the audit system connected in parallel between the hubs and switches. Then, the paper introduces a method based on HTTP packet recognition network security device linkage, which is a technology of information security intrusion detection and prevention based on the network. It is mainly used to solve the existing network security equipment linkage blocking technology limitation poor problem. Finally, the test result shows that the method is practical and effective.

The mathematical model of UTP was expounded, a framework of immune algorithm was given, and simulation experiments were done to validate algorithm. Experimental result shows that proposed algorithm can solve the UTP effectively, and has the advantage of good application value.

Abstract: Multiple export link in campus network, The common DNS server analyze campus network Web server domain to education network IP address, there is no good use of multiple export link. According to the users network, the intelligent DNS server designed in this paper can analyze different IP address. when different operator's network user access campus network Web server, It is through their own operators network, not all users must pass through the education network, therefore, the intelligent DNS server can effectively solve Multiple export link in campus network.

Abstract: This paper describes metallization of PET surface by Sn-free electroless deposition (ELD) of thin copper layer. Prior to introduction to ELD process, the PET surface was plasma-pretreated in argon atmosphere. ELD is a multi-step process involving silanization with TMS, activation with PdCl₂ and copper deposition. Contact angle measurement and XPS analysis were carried out at each stage in order to confirm the chemical change of the PET surface after modification. XPS analysis revealed that the copper surface consisted mainly of Cu₂O, combined with Cu⁰, making Cu-coated PET sheet suitable for the use as substrate for electropolymerization of pyrrole. This study offers an alternative to preparing flexible sensors. This process could be further applied to micro-contact printing technique to fabricate flexible patterned electrodes.

Abstract: An energy model was developed based on the fuel-product concept. The matrix equation for exergy balance of regenerative system was established, and the mathematical model for exergy analysis of thermal system was structured. Exergy losses, exergy loss rate, exergy loss coefficient and exergy efficiency of the main components of a domestic N600-24.2/566/566 power plant were calculated based on this model. The results showed that the exergy efficiency of high pressure heaters are higher than that of low pressure heaters; the exergy efficiency of grade group of the intermediate pressure turbine are higher than the grade group of high pressure turbine and low pressure turbine. The exergy efficiency of the last grade group of low pressure turbine is the lowest. The exergy efficiency of the governing stage and the last grade group of low pressure turbine are 82.999% and 85.911%; the coefficient of exergy loss is maximum in the boiler (39.204%); the exergy effciency of superheater and reheater are 51.52% and 51.7%. Therefore, superheater and reheater have the largest energy conservation potential. Governing stage and low pressure turbine have more energy conservation potential.

Abstract: With the development of component technology, component granularity plays a very import role on the complexity of component composition. How to assemble the component of big granularity How to make the component in the same domain integrated Application framework brings the new era of software-reused technology. But how to construct application framework to make it higher reuse According to the current research of application framework, the paper gives a hierarchy model; The model divides application framework into several layers. Different application framework in different layer has different solutions and the higher the application framework stands in, the lower the probability of change is.
