Advances in mobile networking and information processing technologies have triggered vehicular ad hoc networks (VANETs) for traffic safety and value-added applications. Most efforts have been made to address the security concerns while little work has been done to investigate security and privacy for value-added applications in VANETs. To fill this gap, we propose a value-added application, specifically, a security and privacy preserving location-based service (LBS) scheme for VANETs. For each LBS transaction, the scheme provides authentication, integrity and non-repudiation for both the service provider and the user. A user can obtain the service in an anonymous way and hence user privacy is well protected. However, a tracing procedure can be invoked to find malicious users, thereby efficiently preventing users from abusing the anonymity provided by the system. © Springer-Verlag Berlin Heidelberg 2012.

At present, several severe problems still exist in the process of implementing environmental impact assessment (EIA) of projects. For example, data sources and calculation models are not unified, and the process lacks of public participation. A GIS- based EIA management and technical support system of projects was put forward to solve these problems. Application results of the system were analysised. Main research results and several thinking about the system were presented.

This publication describes the methods used to measure the centrality of inelastic Pb-Pb collisions at a center-of-mass energy of 2.76 TeV per colliding nucleon pair with ALICE. The centrality is a key parameter in the study of the properties of QCD matter at extreme temperature and energy density, because it is directly related to the initial overlap region of the colliding nuclei. Geometrical properties of the collision, such as the number of participating nucleons and the number of binary nucleon-nucleon collisions, are deduced from a Glauber model with a sharp impact parameter selection and shown to be consistent with those extracted from the data. The centrality determination provides a tool to compare ALICE measurements with those of other experiments and with theoretical calculations.

Microscopic Characteristics of Damage Evolution in Ultrapure Aluminum under Tensile Loading

作者： QI Mei-Lan ZHONG Sheng FAN Duan LUO Chao HE Hong-Liang School of Science Wuhan University of Technology Wuhan 430070 Laboratory for Shock Wave and Detonation Physics Research Institute of Fluid Physics China Academy of Engineering Physics Mianyang 621900

A series of plate-experiments are carried out to acquire ultrapure aluminum （purity,. 99.999%） samples with damage. Based on the metallographic of all ＂soft-recovered＂ samples, the characteristics of damage evolution and spallation damage mechanism in ultrapure aluminum are analyzed in detail. Results show that the damage will increase regularly with increasing loading＂ strength. Most of voids appear in the grain boundary and grow alone under tensile loading＂ before they coalesce each other to form big irregular voids. These analysis results are helpful to understand the evolution process of ductile metal dynamic fracture and establish the damage evolution model.

The second generation wavelet packet (SGWP) algorithm was studied based on a lifting scheme, and was successfully used to benoise blasting vibration signals, it laid important foundation for extracting characteristics of blasting vibration signals. The relative energy distribution of each frequency band was obtained quickly and accurately based on the SGWP algorithm, and the energy dominant wavelet packets were chosen to express the time-frequency and energy characteristics of blasting vibration signals. The SGWP algorithm was introduced into blasting vibration effects analysis fields, it provided technical supports and data analysis basis for constructing a large network of blasting vibration measurement system and a control platform, so it had a good application prospect.

The single LED package structure determines the light intensity distribution and the well-designed package structure will be conductive to light emitting and improve its external quantum efficiency. This paper based on the optical package structure of high power LED, in order to analyze the influence of the structure of LED package on optical performance and the feasibility of the packaging structure design, the simplified high power LED optical models were established in Tracepro software. The light distribution curve of LED was obtained and the difference between measured data and simulation result was compared. By changing the LED optical model parameters in the experiment, such as: the shape of reflector, lens design and the position of phosphors to get the light distribution curves under different parameters of package structure and then we analyze the effect of various packaging structures on optical performance to find the package structure optimization, so that it could be used in actual production getting a higher available luminous flux and the light extraction. What's more, designing a package structure which can be achieving the specific light intensity distribution meets the requirements of the LED light source in different areas. © 2011 IEEE.

The resilience deformation rules laboratory test research of the soft soil in the wuhan region in the unloading condition is done through modified triaxial compression apparatus. And the result shows:(1)the critical unloading ratios of the soft soil in wuhan region is 0.28 and *** matter the unloading amount is, no resilience deformation is produced when the unloading ratio is smaller than 0.28 or larger than 0.91,and the resilience deformation is produced when the unloading ration is between 0.28 and 0.91.(2)The void ratio is related to the initial preloading ,the bigger the preloading, the smaller the void ratio, and the bigger the increasing of the void ratio after unloading;the smaller the initial preloading ,the bigger the void ratio, and the smaller the increasing of the void ratio after unloading.(3)The peak resilience rate is linear to the initial preloading. © (2011) Trans Tech Publications.

The laws of cloud-to-ground flash activities are the important fundamental data of lightning protection engineering, which can provide reference for the selection of transmission line route and for the effectual lightning protection measures. Based on the lighting data of the lightning location system (LLS) in Hunan Province from 2002 to 2010, the probability distribution of lightning current magnitude is analysed in this paper. The temporal and spatial distribution of lightning activities in Hunan Province is acquired by counting the cloud-to-ground flashes in different time and different regions with geographic information system (GIS) and grid method. Statistical results show that there exist obvious differences of cloud-to-ground flashes in different time and different regions for the lightning activities in Hunan Province. The lightning activities in some regions are intensive and the cloud-to-ground flash density reached 6.9 flashes per square kilometer per year. The probability distribution of lightning current magnitude in Hunan Province accords with a lognormal distribution approximatively. © 2011 IEEE.
