Finally, a case study, including two intersections is given. The performance of traditional link-based incidence model and proposed route-based incidence model were compared. The impacts of distance between intersections, queues, number of lanes and number of signal phases were analyzed. The results show that the proposed route-based incidence model has the ability to descript the real relationship of adjunct intersections and find the key route for signal coordination.

Abstract:The bovine serum albumin-glutaraldehyde cross-linking process and polycarbonate membrane immobilization process were used to prepare E.coli microbial electrodes for toxic microbial biosensor, and their performance for heavy metals and toxic organic compounds toxicity determination were studied. The results showed that the sensitivity of the E.coli microbial electrodes prepared by GA-BSA immobilization method was very poor, and was not suit for toxicity assessment. E.coli microbial electrode prepared by polycarbonate membrane immobilization process exhibited high sensitivity and good stability for toxicity determination, and it could still suit for the toxicity assessment after 2 months storage at 4℃. The polycarbonate membrane immobilization process is very simple, and it can realize the reuse of electrodes and thus reduced the cost of toxicity determination with microbial biosensor.

Abstract:Abstract: In hogging moment regions, the cracking resistance of the beams can be effectively in creased on adding prestressing to the composite beams with external tendons,. The ultimate resistance of a composite beam prestressed with external tendon is governed by either distortional lateral buckling or local buckling, or an interactive mode composed of the two buckling which is sharply different from the lateral torsional buckling mode in a bare steel beam. Based on the proposed restrained torsional buckling model, inelastic finite element buckling analysis of composite beams in negative bending is investigated, considering the initial geometric imperfection and the residual stress patterns, and the FE results are found agree well with the test results. By varying cross-section parameters, 25 groups of composite beams under negative uniform bending with initial geometric imperfection and different patterns of residual stress in steel beams are studied by means of the FE method. The slenderness of the studied beam is defined and the calculated result is compared with the Chinese Codified steel column design curves. It is demonstrated that the Chinese Codified steel column design curves can be used in assessment of the buckling strength of composite beams with the slenderness defined.

Abstract:Analytical displacements and stresses during expanding hole in plane of viscoelasticity are studied in this paper. According to the basic equations, Laplace transform is introduced to deduce the differential equation of displacement in Laplace space. General expression of displacement and stresses in Laplace space is derived firstly. For stress boundary problem, inverse transforming of above stresses solutions, undetermined function in the solutions can be determined by boundary conditions, and final expressions of stresses and displacement are obtained. The solutions have no restrictive condition of volume incompressible, and are also suit for the cases that spherical tensor have the characteristic of viscoelasticity. The application of the method is given to the problem of H-Kelvin viscoelastic model. Comparison of displacement of different varying velocity shows that displacement is changed gently if radius varied slowly, but displacenmet is larger in end varying time.

Abstract:According to AASHTO TP8 in American standard specification, three point bending fatigue loading test method was modified to evaluate the fatigue properties of asphalt rubber (AR) mixture according to Arizona specification. Material test system was used to strain-control mode. Test result shows that the relation between fatigue life and strain level of AR gap-graded mixture is in a good linearity. Compared to traditional AC-13 gradation mixture which two conventional binders including polymer-modified asphalt (PMA) and conventional asphalt are used, AR gap-graded mixture indicates a better fatigue performance. Rutting test also is used to evaluate the high temperature performance, AR gap-graded mixture whose asphalt content is 1.6 times higher than PMA mixture’s still shows same high temperature performance as PMA mixture. The excellent fatigue performance and high temperature performance of AR mixture is mainly due to three reasons: high crumb rubber content in asphalt make the AR super high performance, gap gradation make the mixture accommodate high asphalt content, high asphalt content and high crumb rubber content in asphalt make the AR mixture excellent fatigue performance.

Abstract:Based on the Hertz contact theory and curve beam theory, the von Mises stress peak value and location were analyzed which is raised in the wheel-rail contact of turntable support hollow wheels, with further analysis using planer strain finite element showed that the decreased wheel section height would increase the wheel flexibility, suppress contact normal stress and raise the wheel strength; but also might cause the peak location of von Mises stress spitted from center of contact area, which could double the stress circulation and reduce wheel fatigue strength. As for the wheel shear stress and rail von Mises stress, there is little influence caused by the variety of wheel section height to the peak value and location.

Abstract:The adsorption of a dye, Methylene Blue, by activated sludge and anaerobic sludge, respectively, was investigated. The roles of extracellular polymeric substances (EPS) including the soluble EPS (SEPS) and bound EPS (BEPS) for the biosorption of activated sludge and anaerobic sludge were further determined. Results show that the relation between remained concentration of the Methylene Blue in mixed liquor and adsorption amount of by EPS, SEPS and BEPS from activated sludge as well as by EPS and BEPS from anaerobic sludge, respectively, was more fitted Langmuir model. Freundlich model was more fitted to SEPS from anaerobic sludge. The amount of adsorbed Methylene Blue by unit mass SEPS were much higher than the corresponding values of BEPS, averaging 14.1 times for activated sludge and 5.8 times for anaerobic sludge. However, the amount of adsorbed Methylene Blue by EPS was mostly contributed by BEPS due to much higher the amount of BEPS than corresponding amount of SEPS for both sludges.

Abstract:A signaling game, where the occupational pension fund management institutions are senders and compete for licenses while the regulation authority is receiver, is set up. Normative analysis shows that the separating equilibrium of market success, where high-ability institutions signal the competence with a cost higher than that low-ability institutions can support in order to prevent them from strategic signal inference of low-ability institutions, exists. And the more the high-ability institutions are, the lower the signaling cost is. With signaling cost data from content analysis empirical study shows the higher probability of winning the licenses is accompanied by higher signaling cost

Abstract:To figure out the influence of frequency intensity to the controllability of structures with closely-spaced natural frequencies, the paper established perturbation equations of closed-loop system between frequencies, mode damping ratios and perturbation parameters beginning from the basic dynamics equations. The analysis focuses on a three-degree-of-freedom structure with closely spaced natural frequencies. The velocity and displacement feedbacks are considered in the calculation. Calculation results suggest that the damping ratios of two modes are decreasing together with the decreasing of the degree of closely spaced natural frequencies which indicate that the controllability of corresponding modes are decreasing to zero. The uncertainties in mass and stiffness matrices are also included in the final part if this paper. Calculation results imply that the coupling degrees of different modes would be changed due to uncertainties and then the controllability will change.

Abstract:Researched on the evaluation methods of asphalt mixture high temperature performance with PR additives added using rutting test, uniaxial penetration test and repeated shear test (constant height) (RSCH). The results of rutting test show that, for the confliction between dynamic stability and rutting depth, it is hard to discriminate the impacts on mixture high temperature performance between PR.S and PR.M. Using extreme shearing strength of uniaxial penetration test and K1, K2, N, γ of RSCH, as the evaluation indexes of asphalt mixture high temperature performance with PR additives added, obtain the same conclusion, and both of the two methods are suitable for high temperature performance evaluation. The four indexes of RSCH not only represent asphalt mixture high temperature performance with PR additives added, but also discriminate the different steps of shearing deformation progress, and represent the mixture damage mechanics.

Abstract:The study sets up a model of a single two-staged supply chain, two sides of which are both oligarchic enterprises. The paper examines how to price the intemediate and the terminal products with the pricing cooperation between the supplier and the manufacturer, and how without the cooperation. The differences hencefore in the gross profit of the supply chain are compared. The result shows that with the pricing cooperation the rate of the increase in the profit is not only positively related to the elasticity of demand for the terminal products and to the cost of the supplier, but also negatively related to the price elasticity of demand for the supplier. Since the excess profit of the whole chain does not represent the one of an individual enterprise, the paper then follows up to probe into the excess profit, suggesting the premises for a stable supply chain cooperated on pricing.

Abstract:Applicability and calculation method of cubic spline interpolation applied in longitudinal deformation curve fitting of cross-river shield tunnel were analyzed, and longitudinal deformation curve of cross-river shield tunnel was fitted by using cubic spline interpolation method, and longitudial deformation curvature of whole tunnel was calculated by curve fitting equation. Based on longitudinal structure analysis model of cross-river tunnel, relationship under different critical state between longitudinal deformation curvature and circular seam stretching-amount was built.Correlation between longitudinal deformation curvature of cross-river tunnel and circular seam leakage was evaluated, by comparing leakage detection results of cross-river tunnel on site.

Abstract:A comparative study is made of the adsorption of a dye,Methylene Blue,by activated sludge and anaerobic sludge.The roles of extracellular polymeric substances (EPS) including the soluble EPS (SEPS) and bound EPS (BEPS) for the biosorption of activated sludge and anaerobic sludge were further determined.Results show that Longmuir model for the Methylene Blue adsorption is fitter to EPS,SEPS and BEPS from activated sludge as well as EPS and BEPS from anaerobic sludge.Freundlich model is fitter to SEPS from anaerobic sludge.The amount of the adsorbed Methylene Blue by unit mass SEPS is more than the corresponding values of BEPS,with an average of 14.1 times for activated sludge and 5.8 times for anaerobic sludge.However,the amount of the adsorbed Methylene Blue by EPS is mostly contributed by BEPS due to much greater amount of BEPS than corresponding amount of SEPS for both sludges.

Abstract:Based on the Hertz contact theory and curve beam theory,an analysis is made of the influence of the circumferential stress of the turntable support hollow wheels on the von Mises stress peak value and location of the wheelrail contact.A further analysis with planer strain finite element shows that the decreasing wheel section height can improve the wheel flexibility,contact normal stress is suppressed and the wheel strength is enhanced.On the other hand,the peak location of von Mises stress may split from central contact area,as a result,the stress circulation is doubled and wheel fatigue strength is affected.As for the wheel shear stress and rail von Mises stress,the variation of wheel section height has little influence on the peak value and location.

Abstract:The study sets up a model of a single twostaged supply chain,two sides of which are both oligarchic enterprises.The paper examines how to price the intemediate and the terminal products with the pricing cooperation between the supplier and the manufacturer,and how without the cooperation.The differences hencefore in the gross profit of the supply chain are compared.The result shows that with the pricing cooperation the rate of the increase in the profit is not only positively related to the elasticity of demand for the terminal products and to the cost of the supplier,but also negatively related to the price elasticity of demand for the supplier.Since the excess profit of the whole chain does not represent the one of an individual enterprise,the paper then follows up to probe into the excess profit,suggesting the premises for a stable supply chain cooperated on pricing.

Abstract:A signaling game,where the occupational pension fund management institutions are senders to compete for licenses and the regulation authority is the receiver,is set up.Normative analysis shows that the separating equilibrium of market success exists,where highability institutions signal the competence with a cost higher than that of lowability institutions to be protected from strategic signal inference from lowability institutions.And the more the highability institutions are,the lower the signaling cost is.Signaling cost data from content analysis empirical study show the higher probability to win the licenses is accompanied with the higher signaling cost.

Abstract:Based on an analysis of the categories and features of the general manufacturing processes,a triangle structure consisted of service needs,service module and service measurement is proposed to be the core process of producer service industrialization with a consideration of the practical needs of manufacturing enterprises and the limitations of the industrial encironment.The service skills and techniques should be modularized according to different functions to be a new tool for the planning and innovation of the producer service industrialization,therefore,an efficient halffinished product(service module) and a design method for relevant measurement system come into being.
