The ultimate goal of smart grid is digitalization, automation, interaction and informatization. If we want to establish smart grid, we must depend on advanced power electronics technology. With the development of the society and the progress of era, the development of economy and science and technology are also very rapid. Therefore, the demand for energy is growing, and the average power grid is aging fast. That leads to the high accident rate and based on the reasons above, in order to meet the needs of times development, our country must use the advanced smart grid, on the basis of the advanced sensing measurement and communication technology. The advanced power electronics technology is the key to smart grid construction. The construction of smart grid really plays an important role in society. © 2014, Journal of Chemical and Pharmaceutical Research. All rights reserved.

Key agreement protocol is one of the fundamental primitives of cryptography. It allows two or more parties to establish secret keys securely in the presence of an eavesdropping adversary. In this paper, two certificateless non-interactive key agreement protocols were proposed under certificateless scenarios, which have obvious advantages in the amount of computation and communication. We perform a security analysis of the schemes. We also show that the second protocol can be used to establish keys between members of distinct domains (under different KGCs). The proposed schemes can be used to construct secret sharing scheme.

Firstly, realizes module partition and simplification of product level CAD model using modularization and hierarchy design flow. Then, identifies the correlative relations of the same rank subassemblies through their individual main control part; identifies the correlative relations between all parts in one subassembly or between all features in one part through main control parameters of each part. Finally, builds an assembly tree based on all association rules for variant design of conveyor, and confirms the feasibility of this method. © (2011) Trans Tech Publications, Switzerland.

According to the special requirements of the minimally invasive surgical robot system, combined the CT images of the lesion site of the patient with the data implied in minimally invasive surgical robot, proposed a new fast feature point based local image registration method, can realize the registration for feature points on special tissue and general tissue. This algorithm introduces Euclidean distance between feature points as the measure of image registration; select the ICP algorithm framework to quickly solve the registration transformation function. Through testing of medical images, experimental results show that the algorithm can match the overall structure of the image information but also align the interested physiological anatomy position of image. Registration results are very satisfactory. This method is a fast, accurate and robust medical image registration method. © 2011 IEEE.

To manage the campus space information effectively, and provide faster query and browse function to user, a straight line optimization algorithm was proposed. The algorithm regards the target node's situation and direction as constraint condition when searching map nodes in road network. The algorithm can reduce the number of searched nodes and increase system-search velocity. To prove the algorithm's practical application, a small campus geographical information system is built on a component geographical-information-system development platform. In this system, the algorithm is used to simulate searching the shortest path between two desired nodes. The simulation result indicates that this algorithm can search the path quickly and reliably. © (2012) Trans Tech Publications, Switzerland.

This study presents a novel approach for configuring the product assembly model in order to rapid design a product family of transportation equipment. The proposed methodology is divided into three phases: namely modular partition phase, product structure configuration phase, and parametric correlation phase. In the modular partition phase, building the incidence matrix through correlation analysis of components under functional, geometric and physical domains, and on this basis, building the similarity matrix and re-aggregating the components into modules by cluster method in fuzzy mathematics. In second phase, a family-oriented product design framework is proposed based on the modular partition results to help designers to concurrently create design solutions. In the last phase, communicating of the module and design framework based on the flow of design parameters information, three types of parameters association and transmission are clarified. The methodology proposed here is illustrated via the example of the design of a screw conveyor. © (2012) Trans Tech Publications, Switzerland.

The uniformity of anchor nodes distribution in a wireless sensor network has a very important impact on the positioning accuracy, but the related research is limited. In this paper, a method for measurement of uniformity is presented, a new criterion of normalized uniformity discrepancy is given, and then a hybrid algorithm for node localization is proposed. Experimental results show that the method for measurement of uniformity is effective and the hybrid algorithm improves the positioning accuracy.

This paper designs a kind of new electrolytic capacitor-less LED (light-emitting diode) driver, which converts the commercial ac voltage to a pulsating current with twice the line frequency driving high-brightness LEDs. As no electrolytic capacitor is used, this driver possesses the unique advantage of long lifetime to match with that of LEDs. A method of injecting the third and fifth harmonics into the input current to reduce the peak-to-average ratio of the output current is also proposed. A 25V, 0.35A output prototype is built and tested in the laboratory, and the experimental results are presented to verify the effectiveness of the electrolytic capacitor-less LED driver and its control method. © (2013) Trans Tech Publications, Switzerland.

A new design scheme of key management tree is proposed for multiple levels multicast communication in wireless network. The network key tree matches with the actual network topology in the scheme and the key nodes in the trees only need to transfer its associated key information. At the same time using the partial order relation between data resources and user ordering in multicast service, users can be grouped; those who have the same ordering relations are in the same group. In this scheme multiple key trees are unified into a single key tree. The amount of the keys stored in key management center (KDC) is calculated and key update process is offered. The simulation results show that the scheme effectively reduces the redundancy key amount and the communication overload produced by the key updating. © 2013 Springer-Verlag.

To improve the ecological performance of pervious concrete, single-factor test method was adopted to study the correlation between compressive strength, flexural strength and splitting strength, the effect of porosity to the strength was analyzed as well. The shrinkage characteristics were compared through experiments between ecological pervious concrete and no-fines pervious concrete, ecological pervious concrete and common concrete. © (2012) Trans Tech Publications.
