Abstract: Small motions will result in heavy influence to the production in high-speed paper machine, therefore, decoupling control is necessary. This passage Puts forward the opposite angles strategies to solve the function of decoupling aiming at solving the difficulty that occurs in practice, like the characteristic of hard-coupling and non-linear. According to the mathematics model of the flow box, decoupling the quantity of the two couplings in the processes. Meanwhile, Introduces the SIEMENS S7-300 PLC and the DCS system that is realized by the it.

Abstract: To suppress the interference in the direct sequence spread spectrum (DSSS) system, a transform domain message data adaptive identify (TISI) algorithm is proposed in this paper, based on two improved algorithms: Power distributing predominance wavelet packets transform (PDP-WPT) and extended BP neural network (EBPNN). Firstly, PDP-WPT is presented to track the interference signal effectively, which improves the convergence rate of TISI. Secondly, the message data can be identified in transform domain by adaptability EBPNN, which has simple structure and enhanced numerical robustness. Simulation results show that TISI can improve the capability of interference suppression by 32% compared with widely used conventional algorithms.

Abstract: In recent years, more enterprises start to take seriously to customer loyalty programs. However, customer loyalty programs do not generate relationship outcomes as people expect. This paper introduces relationship benefits into the research of customer loyalty programs. Using data mining, this study show that relationship benefits in customer loyalty can generate relationship outcomes which are customer satisfaction with customer loyalty programs and customer loyalty on customer loyalty programs. The findings of this paper are directions for future research and managerial implications.

Abstract: In this paper, a 12 bits pipeline ADC (analog to digital converter) based on digitally assisted backend correction is described and behaviorally modeled in Verilog-A language. The Verilog-A model is simulated with Cadence Spectre simulator. In the traditional use of pipeline ADC, the for-end sample and hold amplifier occupies the most power consumption. To decreases the system power consumption, open-loop amplifier is used in the first residual amplify circuit between first and second stage sub-ADC. To correct the nonlinear error introduced by the open-loop amplifier, backend digitally correction is applied.

Abstract: Firefighting task allocation is the core of the forest fire fighting programs. Making use of information entropy method, combined with the fire brigades, fire fighting capability, difficulty and other factors, an analysis in the priority under the conditions of multiple fire sites and fire lines is made, so as to build up fire fighting mission efficient matrix and determine the optimal allocation scheme by using ant colony algorithm. The practice shows that this task allocation model for forest fire fighting under multiple fire sites situation is feasible and practical.

Abstract: The model of buried pipeline is adopted as Euler-Bernoulli beam, which is acted by inner fluid and outer constrained soil. The differential equation of axial vibration is deduced, applying the Hamilton principle. The differential equation of axial vibration is changed into basic form of dynamics equations, considering earthquake excitation as random wave. Utilizing the method of the elasticity time-travel analysis to programming, the responses of the displacement and acceleration at the pipe midpoint obtained, moreover the pipe elements are analyzed. The soil parameter, pipe parameter, earthquake dynamic parameter are considered as the influence elements of pipe response. The characteristic of the soil has an influence on response of velocity and acceleration. Along with soil from soft to hard, the response of acceleration becomes smaller and smaller. In the same soil, the earthquake damage rate of the piping increases along with earthquake intensity increasing.

Abstract: Hardware-software partitioning is the key technology in hardware-software co-design; the results will determine the design of system directly. Genetic algorithm is a classical search algorithm for solving such combinatorial optimization problem. A Multi-objective genetic algorithm for hardware-software partitioning is presented in this paper. This method can give consideration to both system performance and indicators such as time, power, area and cost, and achieve multi-objective optimization in system on programmable chip (SOPC). Simulation results show that the method can solve the SOPC hardware-software partitioning problem effectively.

Abstract: Aiming at the routing protocol in an industrial monitoring system, this paper analyzes the demand of the industrial monitoring wireless routing protocol, proposes a region adaptive routing protocol, and provides the algorithm, procedure and data structure of the route protocol in the industrial monitoring system. Simulation results show that the result of quantitative description compared energy consumption with time delay, this protocol is superior to orientation spreading, sensor protocols for information via negotiation(SPIN) and passing more energy protocols in both aspects, this algorithm can replace the all existing route protocols in the field of industrial monitoring area.

Abstract: This study focused on tensile strength properties inclusive of ultimate tensile strength and elongation values of niobium alloyed ductile iron in as cast and austempered conditions. The tensile specimens were machined according to TS 138 EN 10002-1 standard. Austempering heat treatment was conducted by first undergoing austenitizing process at 900°C before rapidly quenched in salt bath furnace and held at 350°C for 1 hour, 2 hours and 3 hours subsequently. The findings indicated that austempering the samples for 1 hour had resulted in improvement of almost twice of the tensile strength in niobium alloyed ductile iron. Improvement of elongations values were also noted after 1 hour austempering times. Increasing the austempering holding times to 2 hour and 3 hours had resulted in decrement in both tensile strength and elongations values.

Abstract: The damaging variable was defined firstly, mean while the fatigue character of metal rubber was discussed. Then the relationship between damaging variable and cyclic loading times had been summarized through fatigue tests. Finally observed the pattern of fracture face, cavities and flaws of the fatigue wires inner the metal rubber components with electronic scanning microscope, some technical methods of improving the wearing resistivity of metal rubber material had been brought forward.
