Abstract: The traditional firewall is a protect mechanism usually between the internal and external network, through the input and output of data packets in real-time network monitoring, it will make protective response immediately if it find security threats. With short data processing time and high efficiency, it can satisfy most procedures of application, but it has high cost and is difficult to achieve. In this paper, in view of these problems, embedded firewall security protection mechanisms set based AMR processor innovation, given the overall framework of embedded firewall hardware and the design for software architecture ,I selected good performance S3C2410X embedded chip, the embedded firewall network card drivers, key technologies of application research in detail, based on the embedded firewall performance of AMR processor through the contrast test ,the communication rate can reach 15.5Mpbs, 2.15times higher than that of general processor communication performance.

Abstract: Performance evaluation techniques of manufacturing systems are powerful decision support tools especially at system design stage. In this paper, an approximate technique based on decomposition method is proposed for performance evaluation of serial homogeneous transfer lines with unreliable machines and finite transfer-delay buffers. The characteristic of transfer-delay buffers means that it takes some transit time to transfer the parts through buffers, which increases the complexity of transfer lines. In order to address the problem, we firstly transform the initial transfer line into an equivalent transfer line, a serial non-homogeneous transfer line with unreliable machines and finite buffers. Then another transformation which replaces the equivalent line by an approximate homogeneous line is introduced. Finally, decomposition method is used to deal with the approximate model. The accuracy and efficiency of the method are validated by simulation results.

Abstract: A new foam fracturing fluid composed of sodium dodecyl sulfate (SDS), fluorocarbon surfactant (FCS-11), viscoelastic surfactant VES is proposed and developed in this paper. The performances of this fracturing fluid were systematically investigated. The experimental results show that this foam fracturing fluid has good shearing resistance, viscoelasticity and stability. And above all, once broken it has no residue and the damage rate is only 10.12%. These advantages give it a wide application prospect in coal bed methane development.

Abstract: As concerning the high toxicity of organotin paints, the need to develop new environment-friendly antifouling agents has been highlighted. The paper mainly focused on the synthesis of siloxane-acrylic resin and its antifouling performance. The antifouling properties of resins were carried through by the colonization of benthic diatoms (Nitzschia flosterium) and ocean plates of offshore platform. The paper also disclosed that the silicone oil (5.5%, w/w) introduced to siloxane-acrylic resin was significant positive effect for enhancing the antifouling performance in Qingdao ocean.

Abstract: Printing RFID tag is a potential substitute for etching RFID tag as it has advantages in metal waste and substrate selection due to its addictive process. An evaluation of printing tags is conducted on their performance and reliability. It is observed that low printing tag antenna resistance results from slow printing velocity, low printing pressure, high curing temperature as well as long curing time. Printing tags have an equidistant read range with etching tags in the case of low printing antenna resistance when chips are bound to printing tag antennae. Furthermore, printing tags are comparable to etching tags in the sensitivity to environmental temperature and humidity under alternative and constant temperature-humidity tests. It is also demonstrated a weaker ability for printing tags to withstand the mechanical stress than etching tags under the bend test. Experimental results show that printing tags have better performance when their antenna resistances are low.

Abstract: Based on the characteristics of rendering phase, a performance-based policy for job assignment under Distributed Rendering Environments (DREs) is proposed. Firstly, a method of evaluating rendering nodes is designed by taking CPU ratio, RAM size, CPU occupation, RAM usage into account. Furthermore, the corresponding algorithm of job assignment for dividing rendering tasks into sub-tasks on available rendering nodes is presented. Whats more, this algorithms correctness is validated by three groups of experiments thereby which offers quantitative guide for optimal job assignment of rendering.

Abstract: Considering the current agile supply chain performance evaluation methods of automobile manufacturing has defects such as low accuracy, complex computing. This paper proposes the agile supply chain performance evaluation of automobile manufacturing based on regression analysis. Firstly, the index system of agile supply chain performance evaluation of automobile manufacturing is established. Secondly, the agile supply chain performance evaluation model is build based on regression analysis. Finally, the feasibility and availability of this model are verified combined with the numerical examples.

Abstract: Despite of a collection of Quality of Service (QoS) guarantee protocols, no one is able to perform adaptively due to the application dependent nature of those proposed QoS provision algorithms. In this paper a new adaptive model, termed AHP-TOPSIS, is employed to evaluate the performance of two routing protocols DSR and DSDV, based on which the system is capable of switching to the optimal protocol adaptively. The efficiency of the AHP-TOPSIS model is validated by extensive simulations.

Abstract: In this paper, we analyzed new socialist countryside (NSC) construction in Northwest Minorities regions of China as it was observed in rural social economic development since 2005. The analysis was conducted by means of an AHP-based Fuzzy Approach which builds a system analysis technique for multiple criteria decision making,and by four aspects: new farmers、developed agriculture、harmonious countryside and environment for minority populations. The result show that this evaluation index system has good reliability and environment for minority population needs to be paid special attention

Abstract: Talent management has been regarded as a key component to organizations’ success recently. With the scope of this paper, talent management performance evaluation indices system was constructed. Analytic network process (ANP) has been adopted to model a multi-criteria talent management performance evaluation feedback system. Theoretical foundations and application processes of ANP were discussed and dependence and feedback among indices were analyzed. The result of ANP model for the indices system was obtained with Super Decisions software solution. ANP can solve problems with dependent indices effectively rather than analytic hierarchy process (AHP).
