Concrete is a unique composite material that is porous and highly heterogeneous. The durability of steel reinforced concrete in chloride environments is of great interest to design engineers, infrastructure owners and maintainers, and researchers. This review reports recent advances in the knowledge base relevant to the durability of steel reinforced concrete in chloride environments, including: the role of mineral admixtures in concrete durability, the methods of measuring the chloride ingress into concrete, the challenges in assessing concrete durability from its chloride diffusivity, and the service life modeling of reinforced concrete in chloride-laden environments. It concludes with a look to the future, including research needs to be addressed. © 2011 Elsevier Ltd. All rights reserved.

In this paper, a typical correlated double sampling (CDS) complementary metal oxide semiconductor (CMOS) circuit for uncooled infrared focal plane array (IRFPA) is theoretically analyzed, the key factor of CDS CMOS integrated circuit is pointed out, and a new CDS integrated circuit which is high correlative for low-frequency noise is applied in an experimental readout chip for uncooled IRFPA. Theoretical analysis indicates that the sample transfer function of a noise source acted on by CDS processing is related to noise frequency and sampling time interval and the key factor of CDS circuit for reducing or eliminating noise in readout integrated circuit is the sampling time interval. The experimental readout chip with high noise-correlative CDS integrated circuit is fabricated to verify the theoretical analysis, which can be applied to uncooled IRFPAs. © 2010 Elsevier GmbH.

In this paper, a novel method to estimate ARMA time-varying parameter is proposed, based on ESCGM mv grey forecasting model. The estimation procedure of this method consists of two phases, first estimating online ARMA parameter by the least squares method. Then, using ESCGM mv grey forecasting model to forecast the error between θ i and θ̂ i.The model gives an adequate description of the system under consideration. Finally, modify the estimate parameter by the estimate error. Simulation results confirm that the propose method can obtain more accurate estimate time- varying parameter. © (2012) Trans Tech Publications, Switzerland.

Genetic algorithm is one most used evolutionary algorithm in real practice. But when genetic algorithm is used in engineering practice, the slow convergence and poor stability are the main problems. In order to overcome these problems, one new improved hybrid genetic algorithm is proposed here. In this new algorithm, the advantages of artificial immune system and traditional genetic algorithm are combined. And the basic principles in artificial immune system are introduced to improve genetic algorithm. In this new algorithm, the creation of the initial population, the mutation operation, the selection operation, and other genetic operators are all improved. At last, through the simulation experiments of some hard-optimization functions, the proposed new algorithm shows its faster convergence and better stability than a lot of existing algorithms'. © 2012 Springer-Verlag.

The cloud computing is a new computing model which comes from grid computing, distributed computing, parallel computing, virtualization technology, utility computing and other computer technologies and it has more advantage characters such as large scale computation and data storage, virtualization, high expansibility, high reliability and low price service. The security problem of cloud computing is very important and it can prevent the rapid development of cloud computing. This paper introduces some cloud computing systems and analyzes cloud computing security problem and its strategy according to the cloud computing concepts and characters. The data privacy and service availability in cloud computing are the key security problem. Single security method cannot solve the cloud computing security problem and many traditional and new technologies and strategies must be used together for protecting the total cloud computing system. © 2012 IEEE.

The quality of the plastic part depends on the material characteristics, the mold design, and the process parameters, one of which is more important. It involves many sub-design tasks that determine the cost and performance in the early conceptual mold layout design phase. Base-Cover was injection molded with acrylonitrile-butadiene-styrene (ABS)/polycarbonate (PC) [ABS/PC] alloy resin and its process parameters was analyzed by commercial Moldflow software. The optimum gate location and melt filling time were determined, and the optimum injection temperature was obtained by analyzing the shrinkage of the product after molding. An effective regression model was developed to determine the mathematical relationship between the process parameters (mold temperature, melt temperature, injection pressure, injection time, and cooling time) and the volumetric shrinkage by utilizing the analysis data. © (2013) Trans Tech Publications, Switzerland.

A new method of predicting chaotic time series is presented based on a local Lyapunov exponent, by quantitatively measuring the exponential rate of separation or attraction of two infinitely close trajectories in state space. After reconstructing state space from one-dimensional chaotic time series, neighboring multiple-state vectors of the predicting point are selected to deduce the prediction formula by using the definition of the local Lyapunov exponent. Numerical simulations are carried out to test its effectiveness and verify its higher precision over two older methods. The effects of the number of referential state vectors and added noise on forecasting accuracy are also studied numerically. © 2013 Chinese Physical Society and IOP Publishing Ltd.

The software protection is the key technology for the shareware and it can delay and prevent the software reverse and cracking. There are many methods such as junk code, anti-debug, virtual machine, deformation, packers, encryption and verification. The software registration is the most important step of protection and it can be implemented by many forms such as network registration, license key or file, dongle. This paper introduces and compares these protection methods. Some architectures of protection based on encryption and verification are provided and they are realized by RSA encryption and many verification methods which include self verification and key data verification. The method use the exe file and DLL file to protect each other and use the license file to check and provide software function. The method uses the RSA in the license key file to register and it can make it difficult to create the key generator for the cracker. © 2012 Springer-Verlag GmbH.

In this paper, a linear microbolometric array based on VO x thin film is proposed. The linear microbolometric array is fabricated by using micromachining technology, and its thermo-sensitive VO x thin film has excellent infrared response spectrum and TCR characteristics. Integrated with CMOS circuit, an experimentally prototypical monolithic linear microbolometric array is designed and fabricated. The testing results of the experimental linear array show that the responsivity of linear array can approach 18KV/W and is potential for infrared image systems. © 2010 Springer Science+Business Media, LLC.
