With the development of e-commerce, logistics has attracted the attention of big electric business enterprises. Unreasonable picking, slow distribution, and logistics service quality problem have become a bottleneck restricting the development of electronic commerce. This paper put forward design scheme of the integrated storage and distribution system: Electronic business enterprise self-builds or rents distribution centers, then unified manages and dispatches the sellers’ goods, so strengthening the control of logistics; the buyer purchases at random, but receives parcel at once, so improving shopping experience. For this scheme, this paper establishes system dynamics model in which electronic business enterprise can transfer cargoes among the sellers, and carries out computer simulation. In the end, according to the simulation results put forward the proposals. © Springer Science+Business Media Singapore 2017.

Cross Site Scripting (XSS) is a vulnerability of a web application that consists in the exploitation of input validation flaws, with the purpose of injecting arbitrary script code which is later executed at the web browser of the victim. There are three modalities of XSS: reflected-XSS, stored-XSS and DOM-based XSS. The exploitation of stored-XSS can cause more damage compared to the other two modalities of XSS. Through the deep study on the characteristics and trigger mechanism of stored-XSS, and contraposing the input safeguards of web applications, such as filtration and purification, this paper presents an approach and a tool which can generate numbers of attack vectors for stored-XSS automatically. The results of experiments indicate that the attack vectors generated by our tool can effectively detect the existence of stored-XSS in web applications. © AISTI 2016.

La 1.8Ti 0.2MgNi 8.9Al 0.1 alloys have been prepared by magnetic levitation melting followed by annealing treatment. The effects of annealing on the structure and electrochemical properties of the alloys are investigated by XRD, SEM-EDS and electrochemical measurement. For as-cast and annealed La 1.8Ti 0.2MgNi 8.9Al 0.1 alloys, La(Ni,Al) 5 and LaMg 2Ni 9 are the main phases. Annealing not only causes LaNi 2 phase to disappear, but also brings higher compositional homogeneity, which contributes to the improvement of cycling stability. At 60% discharge capacity retention, the maximum charge-discharge cycles, 160 cycles (at 900 °C), is more than three times the minimum, 51 cycles (as-cast). The positive impact of annealing (at 800 °C and 900 °C) on the charge transfer rate at the surface and the hydrogen diffusion rate in the bulk enhances the HRD. The optimum annealing temperature is found to be 900 °C. © 2012 Elsevier B.V. All rights reserved.

In this paper, the (2+1)-dimensional potential Burgers system is investigated by means of the extended homoclinic (heteroclinic) test method. Some new types of exact solutions of the (2+1)-dimensional potential Burgers system are obtained, such as the periodic breather-type solutions, two-soliton fusion wave solutions, Y-type soliton resonance solutions, peakon solutions, and so on. These results enrich the variety of the dynamics of the higher-dimensional nonlinear wave fields. © 2017, Editura Academiei Romane. All rights reserved.

BGP protocol routing update has a large amount of calculation, when the network occurs routing shock in the BGP protocol, the computational complexity would increase rapidly. In order to study the anti shock performance of BGP protocol, has take the low rate denial of service attack as the source of the shock, and studied the selection of the critical paths in the BGP routing topology deeply. Focus on the typical BGP shock attack algorithm as the reference sample, studied the improved method of attack, and analyzed the performance of the BGP protocol by the experimental simulation. © 2015 IEEE.

Effects of aging temperature, holding time and cooling speed on the potentiodynamic polarization curves of 2205 duplex stainless steel were investigated. Microstructure morphologies of the specimens under solution and different aging treatments were observed, the main factors to influence corrosion resistance of duplex stainless steel plate were analyzed. The results show that when aged at 950 ℃, a preferable corrosion resistance can be obtained, while aged at 850 ℃, it is worst. When change the cooling method after aging from air cooling to water cooling, all the uniform corrosion resistance and pitting corrosion resistance are improved.

Finite element method (FEM) is used to predict the tensile and compressive stress-strain curves of single wall carbon nanotube (SWCNT) reinforced polypropylene (PP) composites. The numerical simulations, using shell and tetrahedron elements, are first carried out to investigate the effect of SWCNT orientation on the mechanical properties of the nano-composites. Second, the Grunfest-Young constitutive equation is selected to determine the effect of strain rate and solve the finite element program to analyze the mechanical behavior of the nano-composites. Third, the effect of SWCNT volume fraction is studied. In all cases, the shear and normal stresses distribution along the nanotube axis are investigated and compared with the macroscopic tensile or compressive stresses on the composites. At the same time, the stresses of the interface between SWCNT and the matrix along the loading direction are analyzed. Finally, the effects of SWCNT orientation, content and strain rate on the strength of the nano-composites are studied. From the results obtained, it was shown that strain rate can substantially affect the tensile and shear stresses of the composites, but do not significantly influence the initial tensile or compressive elastic moduli. This is especially the case for SWCNT orientation angles less than 30° and volume fractions higher than 0.74%. © 2013.
