Effect of Ni on Corrosion Resistance of Weathering Steels in Wet/Dry Environments
Authors: Liu Rui , Chen Xiao Ping , Shi Qing Nan
Published: July 2014

Corrosion behavior of a low alloy steel A with 3% nickel content was studied by a wet/dry cyclic test. A commercial weathering steel Q450NR1 was used for comparison. The classical weight loss method was used to evaluate the weatherability of weathering steel, while the iron rust layers formed on weathering steel were analyzed by using SEM, XRD and electrochemical measurements. The results indicated that the corrosion resistance of steels A was better than that of commercial weathering steel Q450NR1 in the wet/dry cyclic test. The addition of Ni promoted the formation of α-FeOOH so as to improve the resistance of the rust. The EIS results indicated that the charge transfer resistance of steel A was bigger than that of steel Q450NR1.

Authors: Fan Shi Ping , Zhang Xiao Di , Wang Hai Li
Published: July 2014

In order to prolong the lifetime of wireless sensor networks, improvement of cluster-head selection mechanism based on LEACH protocol is proposed. To make the energy distribution more uniform, we consider the relationship of the density of nodes, residual energy of nodes and distance between nodes and Sink node. It eliminates the defect of energy consumption imbalance in the network caused by random position of cluster-heads and the problem of premature death of nodes caused by low energy nodes becoming cluster-heads. Simulation results show that compared with LEACH algorithm, the improved algorithm extend the network lifetime.

Published: July 2014

Where in a metropolitan area server controls the network management process and the service process of a node switch and a node server under it, while the node server controls the network management process and the service process of an access switch and a terminal under it. Where in the metropolitan area server or the node server allocates an address to each network device by sending a query packet to each communication port, and establishes a clear network topology on the main control server side during the allocation process, in a main control mode. Thus, during the transmission process of a specific data packet, the main control server (metropolitan area server or node server) directly allocates a corresponding communication link (because it clearly knows the device topology of the whole network), without the need of carrying out route negotiation between each network device, thus a stable transmission rate may be guaranteed, and delay may be avoided.

Improved HEED Based Trust Routing Algorithm for WSNs
Authors: Wang Jun Wei , Sun Wen Yi
Published: July 2014

In Wireless Sensor Networks (WSNs), besides the energy efficient, trust and Quality of Service (QoS) supported should be considered under some circumstances. All of them unveil additional challenges for routing scheme design. Based on Hybrid Energy - Efficient Distributed clustering (HEED) protocol, this paper presents a trust QoS routing algorithm for WSNs. Hierarchical structure is adopted and the trust value of the node is constructed by the direct trust value and the indirect trust value. In HEED, the combination of the trust value and residual energy as the main parameter and the propagation delay as the secondary parameter. The former guarantees the credibility of the data transmission, and the latter ensures the load balance of the entire network. Compared to typical routing algorithms of sensor networks, the proposed algorithm has better performance.

.In this research, ZnCuInS/ZnSe/ZnS quantum dots (QDs) have been studied as an excellent red emitting source for blue GaN LED because of its non-toxic deep red emmission, and large Stokes shift properties. In the paper ZnCuInS/ZnSe/ZnS core/shell quantum dots were prepared with the particle size of 4.5nm. According to the measurement of photoluminescence spectrum emitted by ZnCuInS/ZnSe/ZnS core/shell quantum dots, the emitting peak of 700 nm and the full was achieved as red emitter.It was found that absorption edge and photoluminescence peak shifted to shorter wavelength with decreasing the nanocrystal size due to quantum size effect.Meanwhile, we were prepared ZnCuInS/ZnSe/ZnS core/shell quantum dot light emitting diodes and their photoluminescence properties were studied. After the suitable bias was applied on the films, increasing the ZnCuInS/ZnSe/ZnS QDs concentration in the blue GaN chips, red emission increased with decreasing LED’s blue light.
Hygrothermal Ageing Modeling and Numerical Testing of Unidirectional Polymeric Composites

Published: July 2014

Moisture severely affects aerospace structures and offshore platforms during their service life span. It deteriorates the mechanical performance of polymeric composites through long term and cyclic hygrothermal ageing. This reduction in mechanical performance must be considered during product design to ensure long-term structure endurance. In order to decide the long-term moisture effects on composite components, they are exposed to a rapid moisture conditioning. Presently the available qualified methodologies allowing only simple geometry and an assumption that diffusivity rates are independent of the flow path or direction. Therefore a more advanced finite element method is required. In this research work the finite-element analysis was performed to study the moisture diffusion in unidirectional composites. The final goal for this study was to determine the exposure time for rapid moisture conditioning that produces the most accurate moisture distribution in composite laminates.
Changes in Water Adsorption Desorption Isotherms of Cement Mortars Caused by Carbonation Coupled with Humidification-Drying Cycles
Authors: Son Tung Pham
Published: July 2014

The objective of this work was to examine the influence of carbonation on the water vapor adsorption desorption isotherms of cement materials. Two types of Portland mortars, which were CEM I and CEM II, were carbonated at 20°C, 65% relative humidity and 20% of CO2concentration. The pore size distributions were determined from the water adsorption method. We also studied the coupling effect between carbonation and humidification-drying cycles. The results showed a reduction in microporosity and a small increase in the mesoporosity. The pores clogging due to formation of calcium carbonate was highlighted by the reduction of the quantity of adsorbed water and the decrease in the hysteresis isotherms. The results of this study also indicated that the humidification-drying cycles coincide only from the second cycle because of a difficult evacuation of water during desorption, even at low humidity.

Published: July 2014

Electrochromic composite film consisting of TiO2, chitosan (CS) and carbon nanotubes (CNTs) were fabricated on quartz and FTO substrates by the layer-by-layer self-assembly method (LbL). The multilayer film was characterized by UV-vis spectrum, scanning electron microscopy (SEM), cyclic voltammetry (CV) and chronoamperometric (CA) and in situ spectral electrochemicalmeasurements. The composite material shows high electrochromic performance, with the optical contrast of 11.5% and coloration efficiency of 21.7 cm2/C at 800 nm. The results indicate great promise for the TiO2-based film as a potential material in electrochromic devices.

Published: July 2014

This paper expounds the basic principles of composite element method (CEM).In order to model the discontinuity of the displacement, the asymptotic crack tip displacement fields are added to the CEM approximation for the local enrichment by using the framework of partition of unity. Thus, the crack tip can be inserted into anywhere within the element. The crack-tip displacement mode is given, and some formulas are derived and established in a CEM program. The evaluation of stress intensity is discussed. Numerical simulations illustrate that the proposed algorithm has similar accuracy compared to the FEM, and it has advantage of convenient of pre-process.

This paper was based on the parallel and cross section on the east coast of Xiangjiang river crossing tunnel on Yingpan road in Changsha City, and studied on the affects of partition of it adjacent construction. The conclusions were drawn as followings: When the vertical spacing is larger than 4D, it didn’t need to consider the influence of vertical spacing on parallel interchange tunnels close construction, can be considered as two parallel tunnels. And when the level spacing is larger than 4D, it didn’t need to consider the influence of level spacing on parallel interchange tunnels close construction, can be considered as two intersecting tunnels.
