Abstract: In this paper, the dynamics including boundedness and stability for a general class of complex-valued neural networks with variable coefficients and proportional delays are investigated. By employing inequality techniques and mathematical analysis method, some sufficient criteria to guarantee boundedness and global exponential stability are established for the considered neural networks. As a special case that the coefficients of networks are constants, sufficient criteria are also derived to guarantee the existence, uniqueness and global exponential stability of the equilibrium point. This work generalizes and improves previously known results, and the obtained criteria can be tested and applied easily in practice. An illustrative example demonstrates the feasibility of the proposed results. (c) 2017 Elsevier B.V. All rights reserved.

Abstract: This paper presents a laboratory study aiming to evaluate the performance of electromagnetic (EM) density gauges as a non-destructive tool for hot mix asphalt (HMA) density measurement. In total, 36 HMA testing slabs with different compositions were prepared in laboratory. EM density gauge data were collected from these slabs using two common types of gauges, i.e., PQI 301 and PaveTracker 2701B, and compared with their bulk densities measured by the standard saturated surface dry (SSD) method. It was found that measurement direction, asphalt binder content, mixture air void content, and thickness of the testing slabs do not affect the accuracy of the EM density gauges. However, EM density gauge measurements are affected by the presence of moisture, gradation of asphalt mixture and gauge calibration method. It was also concluded that the accuracy of PaveTracker with mix calibration is comparable to that of the conventional standard method. (C) 2017 Elsevier Ltd. All rights reserved.

Abstract: The relationship between microstructure and diffusion of oxygen in YBCO films are studied in this work. The dislocation structure in magnetron sputtered c-axis oriented YBCO films deposited on (100) SrTiO3 substrates consists of vertical (// c-axis) screw dislocation forests together with layered horizontal (perpendicular to c-caxis) edge dislocation net-works. It is found that in the oxygenation process of YBCO films, oxygen diffusion is greatly enhanced by short circuit paths which we suggest to be the horizontally (perpendicular to c-axis) layered edge dislocation net-works. Base on the structure of c-axis oriented YBCO films, the oxygen diffusion process was examined by applying the cylinder diffusion model. The diffusion coefficient of oxygen and the corresponding activation energy were measured. (C) 2017 Elsevier B.V. All rights reserved.

Abstract: The urban metro system has been widely appreciated as the most important component in urban infrastructures. It plays a critical role in promoting urban social and economic development, and particularly in reducing the urban traffic congestion. However, there are various inherent problems with operating metro systems, which typically involve the crowdedness both at stations and inside vehicles. Both policymakers and academic researchers in China have paid little attention to the crowdedness between metro stations. In order to solve the problem of crowdedness, it is necessary to develop a method to evaluate the level of crowdedness. This work establishes a model to measure the crowdedness between adjacent stations in a metro system based on the load factor principle, passenger standing density, and other factors such as the metro operation schedule and estimations of passenger flows. The Chongqing Metro Line 3 in China is used as a case study to demonstrate the application of the evaluation model. The case study reveals that the model introduced in this study can assist with assessing the crowdedness level between adjacent stations in a metro line. The model is an effective tool for helping the metro management and administration understand the level of crowdedness, apply proper methods to mitigate the crowdedness, and thus improve the quality of the service for those utilizing the metro system.

Abstract: This paper considers fuzzy random shipments and seeks to optimize transportation service prices from a shipper's perspective. To determine suitable prices, the carriers' existing networks and possible reactions are considered, so that the shipper can easily and effectively purchase the required services while optimizing total cost. Two objectives are considered for the shippers, minimizing total cost and total risk. For the carrier, the objective is to maximize carrier profits. Multi-objective expected bi-level programming is developed to incorporate the decision makers' preferences. After establishing the model with uncertain data, multi-objective particle swarm optimization is proposed to solve the model. A case study and analysis are then presented to illustrate the effectiveness of the proposed model and approach.

Abstract: To solve the problem of insufficiency in microscopic performance of foamed asphalt binder, surface energy theory was utilized to analyze the foaming behavior and wettability of asphalt binder. Based on the surface energy theory, the Wilhelmy plate method and universal sorption device method were employed to measure the surface energy components of asphalt binders and aggregates, respectively. Combined with the traditional evaluation indictor for foamed asphalt, the relationship between the foaming property and surface energy of asphalt binder was analyzed. According to the surface energy components, the wettability of asphalt binder to aggregate was calculated to verify the performance of foamed asphalt mixture. Results indicate that the foaming behavior of asphalt will be influenced by surface energy, which will increase with the decline of surface energy. In addition, the surface energy of asphalt binder significantly influences the wettability of asphalt binder to aggregates. Meanwhile, there is an inversely proportional relationship between surface energy of asphalt binder and wettability. Therefore, it can be demonstrated that surface energy is a good indictor which can be used to evaluate the foaming behavior of the asphalt binder. And it is suggested to choose the asphalt binder with lower surface energy in the process of design of foamed asphalt mixture.

Abstract: In the present investigation, microstructure, texture and mechanical properties of Mg-3Mn alloys fabricated by hot extrusion process with the extrusion temperatures of 250 °C and 300 °C were investigated. The results revealed that the samples exhibited the refined microstructure and weakened basal texture. Refined microstructure of the samples was attributed to the dynamic precipitates suppressing the recrystallization grain growth during extrusion process. Weakened basal texture of the samples was explained as a result of particle stimulated nucleation (PSN) promoted by coarsened Mn precipitates altering the texture of extruded profiles during recrystallization by orienting the c-axis of grains at an angle that favors basal slip activity. As a result, the samples exhibited the high tensile elongation and good yield strength at room temperature. © 2017 Elsevier Inc.

Abstract: For reducing the vehicle compartment low frequency noise, the Optimal Latin hypercube sampling method was applied to perform experimental design for sampling in the factorial design space. The thickness parameters of the panels with larger acoustic contribution was considered as factors, as well as the vehicle mass, seventh rank modal frequency of body, peak sound pressure of test point and sound pressure root-mean-square value as responses. By using the RBF(radial basis function) neuro-network method, an approximation model of four responses about six factors was established. Further more, error analysis of established approximation model was performed in this paper. To optimize the panel’s thickness parameter, the adaptive simulated annealing algorithm was im-plemented. Optimization results show that the peak sound pressure of driver’s head was reduced by 4.45dB and 5.47dB at frequency 158HZ and 134Hz respec-tively. The test point pressure were significantly reduced at other frequency as well. The results indicate that through the optimization the vehicle interior cavity noise was reduced effectively, and the acoustical comfort of the vehicle was im-proved significantly. © The Authors, published by EDP Sciences, 2017.

Abstract: Heterogeneous settlement is a common engineering problem in the soft soil foundation or at the juncture between new and old subgrade induced by consolidation settlement, rainfall or earthquake. The reinforced soil structure is commonly applied to reduce the unequal settlement in practices. However, less attention goes to theoretical research on the deformation of reinforcing material under differential settlement condition at present. To improve and simplify the design theory of reinforced earth structure, the deformation of reinforcement in reinforced soil structure is investigated based on the theory of parabolic cable. A method is developed to calculate reinforcement material deformation under differential settlement condition. The feasibility and accuracy of the proposed method are verified by laboratory experiment and theoretical analysis. The method does not require repeated numerical simulation. The calculation results can satisfy the needs of the actual project. © 2017, Science Press. All right reserved.

Abstract: Based on theoretical unsaturated soil water movement, the effects of different bioretention structural layer parameters on ponding, outflow, and runoff regulation were studied under four types of rainfall using a numerical simulation method. Based on the results, ponding was significantly affected by the depth of the surface aquifer. With increasing depth from 20 cm to 30 cm, the overflow control water was increased by about 0.196 m3, while the ponding duration increased by up to 85 min. Bioretention structural layer parameters all had some influence on the outflow of the perforated pipe. As the soil layer to sand layer thickness ratio or the internal water storage zone height increased, the outflow of the perforated pipe was delayed and the peak of the flow decreased, while the increase in aquifer depth led to the advancement of the outflow time and increase in the flow peak. Under the four types of rainfall studied, the average runoff reduction rate of the five types of bioretention ranged from 16.71% to 37.31%, the average reduction rate of the runoff peak ranged from 41.53% to 63.90%, and the average runoff delay time ranged from 97.75 min to 166.50 min. In the case of overflow, the performance of bioretention methods on runoff regulation was significantly reduced, and the effects of structural layer parameters on runoff regulation were weakened. © 2017, Editorial Board of Advances in Water Science.
