Abstract: The key for location-based service popularization in vehicular environment is security and efficiency. However, due to the constrained resources in vehicle-mounted system and the distributed structure of fog computation, disposing of the conflicts between real-time implementation and user's privacy remains an open problem. Aiming at synchronously preserving the position information for users as well as the data proprietorship of service provider, an efficient location-based querying scheme is proposed in this paper. We argue that a recent scheme proposed by Jannati and Bahrak is time-consuming and vulnerable against active adaptive corruptions. Thus accordingly, a postquantum secure oblivious transfer protocol is devised based on efficient NTRU cryptosystem, which then serves as the understructure of a complete location-based querying scheme in ad hoc manner. The security of our scheme is proved under universal composability frame, while performance analysis is also carried out to testify its efficiency.

Abstract: The steel plate shear wall (SPSW) system can provide high lateral force resistance and energy dissipation capacity against seismic loads. Due to the complexity of panel action and wall-frame interaction, developing a high-efficiency analysis method is crucial for the seismic analysis and evaluation of structural systems. This paper explores the feasibility of using endurance time (ET) method to predict the seismic response of high-rise SPSW systems with square concrete-filled tubular columns (SPSW-CFT) with a reduced computational effort. To this end, two high-rise structures with 10 and 20 stories were designed and selected as the prototype structures. The nonlinear time history analysis results under 18 real ground motion records were employed as the basis for comparison. Based on the observations of validation, the global seismic demands and non-cumulative response distribution were compared. The scaling method of ET accelerograms to be consistent with the accumulation-related seismic demands was developed based on the compatibility of strong-motion duration. The investigation results indicate ET method is able to efficiently predict the response parameters with a remarkable reduction of computation cost. ? 2017 Elsevier Ltd

Abstract: A method for stress measurement of steel strands by using electromagnetic oscillation (EMO) circuit only at its both ends, on the basis of magnetic-elastic effect, is proposed in this paper. The basic principle of EMO measurement method is presented, the circuit of EMO is designed, and the experimental system is set up. By stretching the seven-wire steel strand, the stress measurement experiments are carried out. The experimental results indicate that EMO method is an effective approach to measure the stress of steel strands, and it is expected to be used in the stress detection of the existing structures. ? 2018 Elsevier Ltd

Abstract: This paper proposed a new computing method to quantitatively and non-destructively determine the corrosion of steel strands by analyzing the self-magnetic flux leakage (SMFL) signals from them. The magnetic dipole model and three growth models (Logistic model, Exponential model, and Linear model) were proposed to theoretically analyze the characteristic value of SMFL. Then, the experimental study on the corrosion detection by the magnetic sensor was carried out. The setup of the magnetic scanning device and signal collection method were also introduced. The results show that the Logistic Growth model is verified as the optimal model for calculating the magnetic field with good fitting effects. Combined with the experimental data analysis, the amplitudes of the calculated values (BxL(x,z) curves) agree with the measured values in general. This method provides significant application prospects for the evaluation of the corrosion and the residual bearing capacity of steel strand. ? 2018 by the authors. Licensee MDPI, Basel, Switzerland.

Abstract: To address the interfacial concrete separation problem of concrete-filled steel tube arch bridges, 250 m long steel tube models were designed and fabricated for comparative tests, where the vacuum-aided grouting technique and the normal pressure grouting procedure were employed, respectively, to cast the concrete in tubes. The ultrasonic detection method and the cutting inspection method were applied to the experimental concrete-filled tubes to verify the effectiveness of the vacuum-aided grouting technique, of which the working mechanism was also clarified. In turn, the defects and the corresponding measures for the improvement of the original vacuum-aided grouting technique were discussed. Finally, the improved technique was applied in the construction of real bridge engineering to actually realize full-process, vacuumaided grouting. The developed technique greatly reduces the interfacial concrete separation areas as well as the long-term separation distances and effectively ensures the compactness of the cast concrete in the steel tubes. This technique has been patented and generalized to the construction of three super-span arch bridges. ? 2018, Taylor and Francis Ltd. All rights reserved.
