Authors: Zhang Xu , Peng Xiao-Tong , Yang Ao , Lin Chen 
Published: December 2019

Abstract
As a buckling-resistant component, the corrugated steel shear wall was adopted to restrain the local buckling of the steel plate. The mild steel damper was also added to improve the energy dissipation capacity of the structure, forming a new damping energy-dissipation corrugated steel plate shear wall system (DCSW). In order to study the hysteresis behaviour of DCSW, 5 nonlinear FEMs were established by ABAQUS, with the consideration of corrugated steel plate placement, mild steel dampers arrangement and openings form. Their ultimate bearing capacity, ductility, stiffness and energy dissipation performance were compared and evaluated. The results indicated that the DCSW system had better bearing capacity and energy dissipation capacity. The ultimate bearing capacity of structure with corrugated steel plate shear walls and mild steel dampers increased by 37%~43% and 11.4%~13% respectively, combining using those two elements, their ultimate bearing capacity increased by 52%~56%, and their ductility was also improved significantly.

Electropolishing of Nitinol Wires and Its Influence on Corrosion Mechanisms
Authors: Lugovskoy Alex , Krovitsky Tatiana , Mor-Yossef Chen 
Published: December 2019

Abstract
Nitinol is a superelastic and shape-memory alloy often used for the production of vascular stents and surgery implants. Electrochemical polishing is normally used at the preparation stage of stent production. The Electropolishing treatment was performed in 1M Sulfuric acid in 75% Methanol and 25% Glycerine for several treatment times. The corrosion behaviours of Nitinol wires in Hanks’ Balanced Salts Solution and in 3% NaCl at room temperature before and after the treatment were compared. It was found that Nitinol is less active in Hank’s solution that in Sodium Chloride. Tafel slopes built to polarization curves indicate that the mechanisms of corrosion of Nitinol in Hanks’ solution and in NaCl are different. On the other hand, total corrosion current densities are similar in both kinds of media. Plausible equivalent circuits hint that the surface layers formed in Hanks’ solution are not the same as in NaCl. Specimens after the Electrochemical Polishing do not show any differences in the equivalent circuits either in Tafel slopes.

Published: December 2019

Abstract
The effects of Solanum melongena grafting with four different types of Solanum (Solanum diphyllum, Solanum nigrum, Solanum nigrum humile, Solanum alatum) on the biomass and cadmium content of S. melongena were studied by a pot experiment. The results showed that the effects of different treatments on root, rootstock stem, scion stem, scion leaves and whole scion biomass were all smaller than the ungrafted. The whole scion biomass of the treatment ungrafted were 2.67, 2.10, 4.50 and 3.49 times as much as the treatmensts S. melongena grafted with S. diphyllum, S. melongena grafted with S. nigrum, S. melongena grafted with S. nigrum humile, and S. melongena grafted with S. alatum. However, the effects of different treatments on the above indicators cadmium content trends were different. The cadmium content of root and rootstock stem of S. melongena grafted with S. nigrum humile were higher than control, but lower than other three treatments, but the cadmium content of scion stem, scion leaves and whole scion were lowest of all treatments. In conclusion, grafting will affect the growth and absorption of cadmium in S. melongena when it grafted with four different types of Solanum and on the whole, the trentment of S. melongena grafted with S. nigrum humile is the best.

Published: December 2019

Abstract
Considering high risk, long construction period, high construction and maintenance costs, bridge management is asynchronous, unintelligent and inefficient. The purpose of this research is to investigate a new approach with its supporting building information modelling (BIM) and Internet of Things (IoT) tool to enhance the smart management in bridge life cycle. BIM provides detailed geometric and semantic information and IoT contains the management and analysis of the actual condition of the bridge. An example of a super bridge under construction in Xinjiang is used to illustrate the developed system. Results show that the developed system can significantly grasp the quality of the bridge in time, reduce the construction risk and construction period. The developed BIM/IoT-based system is also effective and practical in the quality and risk management among multiple locations, such as smart buildings, smart tunnels, and even smart cities.

Authors: Pan Hong , Xu Hanzheng , Shang Pengpeng , Li Xiaotao 
Published: December 2019

Abstract
In order to explore the dynamic response of curved bridge under the coupling action of transverse and vertical vehicle-bridge, a three-span concrete continuous curve bridge model and a vehicle model are established by using the finite element software ANSYS. The coupling action of transverse and vertical vehicle-bridge is simulated by using the equilibrium and geometric coordination conditions of the forces between the two models, and the transversevibration of the vehicle model is considered. The dynamic response of curved bridge is studied by establishing the dynamic model of vehicle-bridge interaction. The results show that the maximum transverse force of 1# mid-span section increases by 1.43% under the action of 70t vehicle weight compared with that without considering the coupling effect of transverse and vertical vehicle-bridge; and the maximum transverse displacement of 1# mid-span section increases by 10.25% compared with that without considering the coupling effect of transverse and vertical vehicle-bridge. Therefore, it is necessary to take into account the vehicle-bridge coupling in the dynamic response analysis of curved bridges; the transverse displacement of curved bridges can be prevented by limiting load and weight.

Abstract
In order to obtain the truck-specific ramp deceleration lane length index for passenger and cargo separation, the UMRR chain Kepler radar speedometer is used to collect the vehicle speed data under the free-flow state of the ramp feature points (starting point, diversion point and small nose point of the transition section). The KS normal distribution test is carried out on the sample data. On the basis of satisfying the test requirements, the speed and acceleration characteristics of the deceleration lane vehicle are analysed, and then the parameters in the secondary deceleration theory are re-determined. Based on this, the deceleration lane length value of the truck-specific ramp is calculated.

Experimental Research and Theoretical Analysis of Surface Contact Angles of Different Materials
Authors: Xia Peng , Li Shuaicai , Tao Leren 
Published: December 2019

Abstract
Surface properties play an important role in the formation of frost crystals. The smaller the contact angle formed by droplets on the metal wall, the larger the contact area with the cold surface, thus accelerating the freezing process and making frost crystals easier to form. In this paper, the water droplets on the surface of zinc, aluminium, brass and red copper with the same specifications were observed microscopically. The images were binarized by Rising View software. The contact angles of the surfaces of different materials were measured, and the theoretical analysis and calculation were made by geometric method. It is found that the water droplets are spherical coronal on the horizontal surface. With the increase of the inclination angle of the specimen, the water droplets will incline downward, and the contact angle of the surface will be larger in front and smaller in back, and the difference between the two is equal to the inclination angle of the specimen. When the inclination angle exceeds the critical inclination angle, the water droplets will slip and no longer adhere to the metal surface.

Authors: Lv Qingzhi 
Published: December 2019

Abstract
In this paper, the VAR model is used to construct the dynamic relationship between crude oil price and economic growth, price level and monetary policy. Granger causality analysis shows that oil price fluctuations are the Granger cause of economic growth rate, monetary policy and other economic indicators. Through VAR(2) model and impulse response analysis, the main impacts of oil price rise on China’s economy are: it will increase the economic growth rate in a short time; through the aggregate demand to pull and increase the cost of such two ways to increase the price level; it makes it more difficult to implement monetary policy effectively. On the whole, although the international oil price and China’s economic variables are complex and changeable, the economic system composed of international oil price, economic growth, price level and money supply is stable.

Authors: Yuan Pei , Liu Weiguo , Mao Wenqi , Ye Huisheng , Ou Lezhi 
Published: December 2019

Abstract
DC magnetic bias refers to a series of complicated electrical, magnetic, force, sound, heat and other abnormal phenomena caused by DC current intrusion into the transformer winding, which causes half-cycle saturation of core flux, which will seriously endanger the safe and stable operation of the transformer. Since the 1000kV UHV substation is very important in the power system, and the UHV transformer has lower DC current tolerance than the general transformer, it is necessary to accurately evaluate the DC bias risk of the UHV transformer during the design phase. This paper provides a reference for the DC bias magnetization prevention and control of UHV transformers by modelling and analysing the DC bias magnetization of 1000 kV UHV substation in Changsha. .

Authors: Hu Zhengfeng , Tan Min , Zhang Kefeng 
Published: December 2019

Abstract
In this study the effect of root growth and root length distribution on seasonal transpiration of winter wheat grown in a medium European soil under a temperate maritime climate was numerically investigated using an agro-hydrological model. Rooting depth of the crop was assumed to be proportional to the above-ground dry weight, and root length distribution was exponential from the soil surface with a shape parameter controlling root distribution. Results show that in dry growing years only about half potential transpiration was met, and more than 90% potential transpiration was supplied in wet growing years in both scenarios with a different shape parameter value. The seasonable transpiration with the shape parameter equal to 1 increased by 0.7% to 12.8% with the overall value of 5.6% over the simulation period of 21 years, compared with those from the shape parameter value of 3.

Authors: Aris A , Syaf H , Yusuf D N , Nurgiantoro  
Published: December 2019

Abstract
The urban air temperature has gradually increased in almost all cities in the world, including Kendari City. This is indicated by the increase in building materials and reduced vegetation biomass in urban areas that have consequences of increasing surface temperatures and forming a micro-climate phenomenon called urban heat island (UHI). The aim of this study is to analyse of UHI intensity in Kendari region for the periods 2001-2014-2019, based on the distribution of land surface temperature (LST), which was analysed through thermal infrared (TIRS) and operational land imager (OLI) sensors onboard Landsat-7 and Landsat-8, each image has an atmospheric correction and brightness temperature. The results show the intensity of UHI during the 2001 to 2014 period increased by 2.44 °C, while in 2019 the intensity decreased by 2.27 °C from the previous period. These fluctuations are closely related to the land cover (LC) changes especially in built-up areas, vegetation, and bare soil as the effects of the urbanization process, and parameters of the normalized difference vegetation index (NDVI).
