Abstract: Collaborative two-echelon logistics joint distribution network can be organized through a negotiation process via logistics service providers or participants existing in the logistics system, which can effectively reduce the crisscross transportation phenomenon and improve the efficiency of the urban freight transportation system. This study establishes a linear optimization model to minimize the total cost of two-echelon logistics joint distribution network. An improved ant colony optimization algorithm integrated with genetic algorithm is presented to serve customer clustering units and resolve the model formulation by assigning logistics facilities. A two-dimensional colony encoding method is adopted to generate the initial ant colonies. Improved ant colony optimization combines the merits of ant colony optimization algorithm and genetic algorithm with both global and local search capabilities. Finally, an improved Shapley value model based on cooperative game theory and a cooperative mechanism strategy are presented to obtain the optimal profit allocation scheme and sequential coalitions respectively in two-echelon logistics joint distribution network. An empirical study in Guiyang City, China, reveals that the improved ant colony optimization algorithm is superior to the other three methods in terms of the total cost. The improved Shapley value model and monotonic path selection strategy are applied to calculate the best sequential coalition selection strategy. The proposed cooperation and profit allocation approaches provide an effective paradigm for logistics companies to share benefit, achieve win-win situations through the horizontal cooperation, and improve the negotiation power for logistics network optimization.

Abstract: The mechanical, dynamical and thermodynamic properties of Al-3wt%Mg have been investigated using the first-principles method. The calculated structural parameter is in good agreement with previous works. Results for the elastic modulus, stress-strain relationships, ideal tensile and shear strengths are presented. Al-3wt%Mg is found to have larger moduli and higher strengths than Al, which is consistent with its exploitation in Al precipitate-hardening mechanisms. The partial density of states (PDOS) show that the partly covalent-like bonding through Al p-Mg s hybridization is the origin of excellent mechanical properties of Al-3wt%Mg. The phonon dispersion curves indicate that Al-3wt%Mg is dynamically stable at ambient pressure and 0 K. Furthermore, the Helmholtz free energy Delta F, the entropy S, the constant-volume specific heat C-V and the phonon contribution to the internal energy Delta E are predicted using the phonon density of states. We expect that our work can provide useful guidance to help with the performance of Al-3wt%Mg.

Abstract: Sliding puzzles are classic and ancient intellectual problems. Since the amount of states in a sliding puzzle equals to the factorial of the number of tiles including the blank tile, traditional algorithms are only effective for small-scale ones, e.g. 8-puzzle. This article proposes a novel and efficient algorithm called DSolving for large-scale sliding puzzles. DSolving adopts direct solving manner. It does not need to store the intermediate states. Therefore, theoretically, it can solve any scale sliding puzzle. For general number tiles except the after-mentioned ones, DSolving adopts an efficient method to quickly move them to their target locations along shortest paths. For the top-right 3×2 corner sub-puzzles beginning with the last two positions in each row, DSolving constructs a state transition table (STT), which can ensure those two number tiles in the top-right corner be moved and placed correctly. The last two rows of tiles are considered as several 2×3 sub-puzzles, and another STT is constructed to solve these 2×3 sub-puzzles. These two STTs reduce corresponding problems to simple table-look-up operations. Experimental results show that DSolving exhibits high time-efficiency and stability. It takes only 4-5ms to solve a random instance of 20×20 sliding puzzle on a general personal computer.

Title:Tribological characteristics of piston rings in a single-piston hydraulic free-piston engine

Abstract: Purpose – A free-piston engine (FPE) is an unconventional engine that abandons the crank system. This paper aims to focus on a numerical simulation for the lubricating characteristics of piston rings in a single-piston hydraulic free-piston engine (HFPE). Design/methodology/approach – A time-based numerical simulation program was built using Matlab to define the piston motion of the new engine. And a lubrication mode of piston rings was built which is based on the gas flow equation, hydrodynamic lubrication equation and the asperity contact equation. The piston motion and the lubrication model are coupled, and then the finite difference method is used to obtain the piston rings lubrication performances of the FPE. Meanwhile, the lubrication characteristics of the new engine were compared with those of a corresponding conventional crankshaft-driven engine. Findings – The study results indicate that compared with the traditional engine, the expansion stroke of the HFPE is longer, and the compression stroke is shorter. Lubrication oil film of the new engine is thicker than the traditional engine during the initial stage of compression stroke and the final stage of the power stroke. The average friction force and power of the hydraulic free piston engine are slightly lower than those of the traditional engine, but the peak friction power of the FPE is significantly greater than that of the traditional engine. With an increase in load, the friction loss power and friction loss efficiency decrease, and with a decrease in equivalence ratio, the friction power loss reduces, but the friction loss efficiency decreases first and then increases. Research limitations/implications – In this paper, only qualitative analysis was performed on the tribological difference between conventional crankshaft engine and HFPE, instead of a quantitative one. Practical implications – This paper contributes to the tribological design method of HFPE. Social implications – No social implications are available now, as the HFPE is under the development phase. However, the authors are positive that their work will be commercialized in the near future. Originality/value – The main originality of the paper can be introduced as follows: the lubrication and friction characteristics of the new engine (HFPE) were investigated and revealed, which have not been studied before; the effect of the HFPE's special piston motion on the tribological characteristics was considered in the lubrication simulation. The results show that compared with the traditional crankshaft engine, the new engine shows a different lubrication performance because of its free piston motion.

Abstract: A movable scaffolding system (MSS) can improve the automation of bridge construction and therefore was widely used. However, for bridges with small radius curves, there are many difficulties when the huge MSS moving from one span to the next. In this paper, a new huge MSS (around 1500 t) for passing span of a curved bridge was designed and presented to complete the erection of the second longest span rail transit cable-stayed bridge in in the world whose north approach bridge features high piers, long spans, and a small radius. Schemes for the MSS passing span of the curved bridge were introduced. The finite element analysis (FEA) and field tests of the MSS when passing span were carried out. The calculative and field measured results were compared and analysed. The comparisons and analyses indicate that the small radius curve of the bridge and uncertainties during the erection have great effect on field measured stresses and displacements of the MSS. The bridge was competed smoothly and efficiently using the MSS with consideration of the calculations and filed measurements.

Abstract: To solve the cracking problem of cast-in-place concrete in shear pockets and seams of the traditional composite beams with conventional steel-precast concrete decks, a new type of prefabricated steel truss-concrete (PSTC) composite beam with pre-embedded shear studs (PCSS connector) was proposed. To investigate its crack resistance, the construction method of PSTC composite beam was illustrated based on the introduction of basic concepts. And three prestressed PSTC composite beams were tested under hogging moment, and in the limit state of cracking under the hogging moment, the section strain characteristics of PSTC composite beams were analyzed. In terms of the section strain coordination condition considering the slip effect and the shear-slip constitutive relation of PCSS connector, the static equilibrium equations of the concrete deck and the steel beam in the micro-segment of the PSTC composite beam were established respectively, and the formulas were deduced for calculating the cracking load of PSTC composite beam considering the slip effect. The results show that, for the PSTC composite beam, firstly, it is necessary to pre-embed a shear steel plate with studs in the precast concrete deck, and then the precast concrete deck is installed on the steel truss, with application of longitudinal prestress. Finally the concrete deck is combined with the steel truss by welding the vertical steel plate of shear connector and the flange of the upper chord. The initial crack appears on the edge of the concrete deck near the loading point, the cracking load increases with the increase of prestress, and the initial crack of the adjacent prefabricated deck appears later than that of the concrete deck, so there are no obvious weak parts of crack resistance for the PSTC composite beam. The calculating results coincide well with the experimental data, which can provide a reference for similar bridges. ? 2017, Editorial Department of China Journal of Highway and Transport.

Abstract: To provide a reference for design and construction of the shear connectors in prefabricated composite beam, experiments focused on the arrangement of shear studs in this type of beam were conducted to investigate shear behavior as well as the ultimate capacity of shear connectors under the longitudinal loading, taken the effect of loading levels and shear stud numbers into consideration. Using pull-out test method, two types of shear studs, 12 specimens for each type, were designed to investigate the shear mechanism of specimens from loading to failure. According to the theory of confined concrete, the concrete in the core region near the studs of the specimen was analyzed and the calculation method of ultimate shearing capacity was proposed, comparing calculation result and test result as well. The results show that, compared with the test results of the conventional shear studs, shear capacity of the prefabricated shear studs is 20% higher, the peak slip is nearly doubled and the concrete deck is slightly cracked. The load-slip laws of the two groups of specimens show small differences during the elastic stage. For the prefabricated shear studs, the peak point of the load-slip curve moves upwards and backwards during the elastic-plastic stage, with their good integrity in the failure stage. Moreover, based on the shear capacity calculated formula considering the constrained reinforcement of concrete, the calculated results coincide quite well with the test results, with the reserved safety meeting the requirement of the code. Finally, the constrained effect of the concrete around the shear studs has great importance in improving the longitudinal shear capacity and the ductility. ? 2017, Editorial Department of China Journal of Highway and Transport.

Abstract: Sliding puzzles are classic and ancient intellectual problems. Since the amount of states in a sliding puzzle equals to the factorial of the number of tiles including the blank tile, traditional algorithms are only effective for small-scale ones, e.g. 8-puzzle. This article proposes a novel and efficient algorithm called DSolving for large-scale sliding puzzles. DSolving adopts direct solving manner. It does not need to store the intermediate states. Therefore, theoretically, it can solve any scale sliding puzzle. For general number tiles except the after-mentioned ones, DSolving adopts an efficient method to quickly move them to their target locations along shortest paths. For the top-right 3 × 2 corner sub-puzzles beginning with the last two positions in each row, DSolving constructs a state transition table (STT), which can ensure those two number tiles in the top-right corner be moved and placed correctly. The last two rows of tiles are considered as several 2 × 3 sub-puzzles, and another STT is constructed to solve these 2 × 3 sub-puzzles. These two STTs reduce corresponding problems to simple table-look-up operations. Experimental results show that DSolving exhibits high time-efficiency and stability. It takes only 4–5 ms to solve a random instance of 20 × 20 sliding puzzle on a general personal computer. ? 2016 Informa UK Limited, trading as Taylor & Francis Group.

Abstract: An effective temperature correction method for dielectric sensors is important to ensure the accuracy of soil water content (SWC) measurements of local to regional-scale soil moisture monitoring networks. These networks are extensively using highly temperature sensitive dielectric sensors due to their low cost, ease of use and less power consumption. Yet there is no general temperature correction method for dielectric sensors, instead sensor or site dependent correction algorithms are employed. Such methods become ineffective at soil moisture monitoring networks with different sensor setups and those that cover diverse climatic conditions and soil types. This study attempted to develop a general temperature correction method for dielectric sensors which can be commonly used regardless of the differences in sensor type, climatic conditions and soil type without rainfall data. In this work an automated general temperature correction method was developed by adopting previously developed temperature correction algorithms using time domain reflectometry (TDR) measurements to ThetaProbe ML2X, Stevens Hydra probe II and Decagon Devices EC-TM sensor measurements. The rainy day effects removal procedure from SWC data was automated by incorporating a statistical inference technique with temperature correction algorithms. The temperature correction method was evaluated using 34 stations from the International Soil Moisture Monitoring Network and another nine stations from a local soil moisture monitoring network in Mongolia. Soil moisture monitoring networks used in this study cover four major climates and six major soil types. Results indicated that the automated temperature correction algorithms developed in this study can eliminate temperature effects from dielectric sensor measurements successfully even without on-site rainfall data. Furthermore, it has been found that actual daily average of SWC has been changed due to temperature effects of dielectric sensors with a significant error factor comparable to ±1% manufacturer’s accuracy. ? 2017 Elsevier B.V.

Abstract: In this paper, an energy efficient power allocation scheme is proposed for a distributed massive multiple-input multiple-output (MIMO) system with a circular antenna array. Single-antenna users simultaneously transmit signal to the base station (BS) with a large number of distributed antennas. The tight approximation of the energy efficiency (EE) is derived in closed form expressions. Through jointly optimizing the power allocation and the antenna number of BS, an NP-hard problem is formulated to maximize the EE. The equal power allocation is proved to be optimal given the total transmit power and the number of antennas. Finally, the optimal antenna number is determined by one dimension search. It is noteworthy that the NP-hard problem is solved by one dimension search. Simulation results validate the accuracy and the low-complexity of our proposed scheme. ? 2017 by the authors.
