Authors: Yang Sheng Hai , Huo Guo Feng , Xia Jiao Yun , Yang Hai Ping
Published: July 2011

Zirconium ethoxide was synthesized by direct electrochemical reaction of anhydrous ethanol with sacrificial zirconium anode in the presence of tetraethylammonium chlorides (Et4NCl) as a conductive agent. The samples of products were characterized by Fourier transform infrared spectra (FT-IR) and Proton nuclear magnetic resonance spectroscopy (1H-NMR). The experiment results show that direct electrochemical synthesis of zirconium ethoxide has high current efficiency and abundant synthetic product compared with the conventional chemical methods. The behaviors of Zr in Et4NCl ethanol solutions were measured through potentiodynamic polarization, cyclic voltammetry, and potentiostatic current-time transient techniques. Effects of the temperature, scanning rate and the Et4NCl concentration were investigated. The results indicate that the electrochemical dissolution of the metal in anhydrous ethanol is a process of corrosive pitting. The rate of pit nucleation and pit growth increases with increasing of temperature and the Et4NCl concentration.

Authors: Liang Zheng Yong , Lü Chun Xu
Published: July 2011

Fluorinated benzaldehydes and diphenyl ketones were synthesized via halogen-exchange fluorination in less polar aprotic solvents in the presence of phase transfer catalyst, with or without the irradiation of microwave. The products were easily obtained with significantly enhanced yield and selectivity with microwave irradiation when compared with conventional heating. The yield of products was in the range of 52.0%~94.2%, and the reaction time can be shortened by more than 90% at most in comparison with common heating. In addition, special microwave effect is obvious when reaction was carried in medium polar aprotic solvents. Therefore, more aprotic solvents can be used in halogen-exchange fluorination under the irradiation of microwave.

Authors: Zhang Jiu Peng , Xu Li , Pei Jian Zhong
Published: July 2011

In this study, the stiffening effect of fillers on asphalt binders was characterized through micromechanics and rheology methods. The dynamic shear rheometer (DSR) was used to measure viscoelastic properties of asphalt mastic. Mechanical volume filling effects and additional interacting mechanisms within mastic systems are discussed on the basis of micromechanics-rheology model to predict the complex shear modulus of asphalt mastic from the measured mastic data. It is observed that the phase angle ranges from 88.8o to 89.0o, does not significantly change due to limestone fillers addition. The analytical model prediction of complex shear modulus based on the dynamic shear modulus can be used. Using the nonlinear regression, the Einstein coefficient KE is 4.22, 5.09 and 7.44 for asphalt mixed with limestone, cement and hydrated lime, respectively. Beside, the SEM results explain why the mastic system with hydrated lime shows the highest KE. The behavior of hydrated lime fillers filled mastics is probably due to physico–chemical interaction, which can be validated by further research.

Authors: Kim Sung Gyu , Park Byung Joo
Published: July 2011

This paper proposes a solution for solving packet loss and out-of-sequence problems in standard Hierarchical MIPv6. These days, the need for Mobile IPTV on Wireless devices which provide IPTV is rapidly increasing. Due to the development of Internet-based IPTV and wireless devices using an increased Mobile network, which uses mobile devices, handovers during movement are bound to be inevitable. Standard MIPv6 (Mobile IPv6) in the event of a handover needs more time to process which will lead to problems, such as packet loss and the out-of-sequence problems. For these reasons, providing wireless services is more difficult than providing wired services. To solve these problems, many protocols have been developed, but a lot of challenges still remain to be solved. We proposed a scheme to solve the packet loss and packet out-of-sequence problems and it also focused on providing better services for Mobile IPTV. We used HMIPv6 (Hierarchical Mobile IPv6) for improvement of handover procedures.

Published: July 2011

In order to evaluate software trustworthy level in quantitative method, it is the key how to effectively integrate numerous of evidence items to analyze software trustworthiness. Combing with analytic hierarchy process (AHP), a software trustworthy level evaluation model based on layered idea is proposed. The model is applied to evaluate the trustworthy level of a kind of software. Based on improved trustworthy software triangle model, a single evidence item is analyzed to decide that it contributes only to one single trustworthy attribute or to multiple trustworthy attributes. Then, all evidences are grouped to different evidence groups according to the evidences’ different contribution to different trustworthy attributions. After that, the evidence group is used as an individual layer between evidence level and trustworthy attribute level. Finally, the quantitive evaluation to software trustworthy level is done from the evidence layer in the bottom to the evaluation level in the top. AHP is used to set the weight. The proposed evaluation model balances the complexity of theory and convenience of operation effectively. The layered AHP is easy to realize in the model. In order to analyze the model performance, a kind of software system is used as object in the simulating experiments. Experimental results show that the proposed model can evaluate the software system effectively.

Published: July 2011

When describing a document in Vector Space Model (VSM), it often assumes that there is no semantic relationship between words or they are orthogonal to each other. In order to improve the inaccurate document description, a new document description method has been proposed in this paper by introducing a concept-word, which calculates the semantic similarity between words based on HowNet ontology database. Comparative experiments show that the new method can not only improve effectively the effect of document feature description in VSM, but also reduce significantly the dimension of a document vector.

In this paper, we come up with an optimal DSR based on ant colony algorithm to improve the operational efficiency of wireless sensor network. Firstly we introduce the concepts of virtual grid and effective information propagation radius, then accord to the sensor’s translational speed and the rest energy to estimate the sensors’ persistence of life; besides, depend on the radius of effective information propagation we set the size of virtual grid and use this virtual grid as the unit to divide clusters. Finally, we realize the goal of steady information translation and effective energy usage. Under the same simulation environment, we compared the running results of DSR, LEACH and HDSR, the results illustrate that HDSR is not only able to improve the efficiency of information transportation but also equipoise the energy cost, it effectively increases the robustness of WSN.

Published: July 2011

In order to identify the Amur tiger individual more accurately and conveniently, a new characteristic of Amur tiger is proposed in this paper. The images of the Amur tiger fur’s texture were first processed by computer through the method of image processing technology. After that it was easier to extract the characteristic from the image. In the Amur tiger’s sideways image, the eigenvalue is the ratio of the specified texture’s area in tiger sideways and standard area. The specified texture’s area is formed with the black stripes whose shape is similar to diamond. Standard area is a triangle area and its vertices are the spine’s highest point, abdomen’s lowest point and caudal vertebra’s central point. Experiments show that the characteristic is a unique characteristic of the Amur tiger individual and it can be used to identify the Amur tiger individual.

The modal includes the geometric nonlinearity due to large deformation, material nonlinearity, the anisotropy of rubber-cord composites, the nonlinear boundary conditions from tire-rim contact and tire-pavement contact. The model can be used to simulate the changes of a rolling tire and calculate the tire deformation for various operating conditions. The profile of the inflated tire is studied experimentally and numerically. The simulation result is in good agreement with the test result. Some contact problems, such as the tire deformation, the shape of contact area, the contact pressure distribution, are discussed in detail.
