Summary The point cloud data of the tunnel get by 3D laser scanning can provide a data basis to a large number of subsequent tunnel construction tasks, and can be used as the design basis of route adjustment of alignment and gradient, thus can greatly reduce the manpower required for the field data acquisition, material and financial resources.
According to the ground laser 3D scanning point cloud data can generate 3D visualization model which can provide a better simulation environment for the running of the train, therefore avoid the repeated collection of field data and save the engineering cost.

Maintenance engineering is too technical, thus housing fund management center can barely reconcile “authority” and “impartiality”[2].
Supervision costs consist of a lot of manpower, financial and material resources consumed in the process of monitoring activities.

Analysis of Leveling Strategy for a plate Mill Li Cui1, a, Xianlei Hu1, b and Xianghua Liu1, c 1 State Key Laboratory of Rolling and Automation, Northeastern University, Shenyang, China a cuilitianda@163.com, bhu_xianlei@263.net, cliuxh@mail.neu.edu.cn Keywords: Leveling strategy, Plate mill, Plastic deformation ratio Abstract.
Plastic deformation ratio is one of the most important factors, which is considered as the feature of fine plates and it should be at least 70% for engineering application [4~7].
Leveling for plate is an alternating loading and unloading elastic-plastic process, so the material obeys to Hooke's Law in the elastic range, but when the plastic deformation occurs, it obeys Prandtl-Reuss incremental plastic theory and satisfies the Mises yield criterion.

But how to pick up the complete lifetime information from the failure data is the key problem, for nearly all the test specimen in the step-stress test experience cumulative failure [1-5].

Nanostructured Mesoporous Thick Films of Titania for Dye-Sensitized Solar Cells John Wang, and Yu Zhang Department of Materials Science and Engineering, National University of Singapore Singapore 117576 e-mail: msewangj@nus.edu.sg Keywords-Dye-sensitized solar cells; supramolecular templating; mesoporous; titania; morphology Abstract—For energy harvesting, such as in dye-sensitized solar cells, thick films of nanostructured mesoporous titania are inevitably required.
The key component of DSSCs is the wide bandgap semiconductor as the photoanode that is required to possess large surface area for high dye loading and controlled nanostructure for efficient electron transport.

Research on Aluminum Plate Reversible Hot-rolling Mathematical Model and Schedule Wang HaiXiong1,a, Li JiBin1,2,b, Liu HaiJun2,c, Wang ChangSheng2,d 1Key Laboratory for the Advanced Optical Manufacturing Technoloy of GuangDong, China 2mechatronics and Control Engineering College of ShenZhen University, Shenzhen, China awhx131@126.com, blijb@szu.edu.cn, cliuhaijun@163.com,dwangchangsheng1985@163.com Keywords: rolling schedule, mathematical model, two-roll reversible hot-rolling, strip rolling.
Many scholars and engineering technical personnel have paid more attention to the optimization of rolling schedule with the development of computer technology[1,2,3,4], and carried out many works, however, these works are only for steel rolling, and rolling process conditions of steel plate and aluminum plate is quite different, so these are not practical for hot-rolling production of aluminum plate.
The amount of width spread may be negligible, so the rolling force can be calculated with the Sims model [5,6]: (1) In the equation: is contact arc length, plate width, σaverage metal flow stress, force geometry factor; tension coefficient. 2.2 Rolling temperature model Rolling temperature not only affects rolling force, but also plays a decisive role on the internal organizational structure of the plate material, so temperature control of rolling process is very important.
In this figure, HFA and HFC is the last thickness when replace the maximum pass with the minimum pass , HIA and HIC is the exit thickness of intermediate pass when replace the maximum pass with the minimum pass , The key issue of this algorithm is to determine the HID point with the ordinate of A and C point.
Material is 1100 aluminum, and its size is 6000mm×1050mm×320mm.

Introduction During the last years, fuel cells have attracted considerable scientific and engineering interest because they present high efficiency and very low environmental impact.
The mass transport within a fuel cell is a key factor to its performance.
In particular, anode is divided into three regions: an electrolyte region, an active catalyst region (catalyst layer) that provides a catalytic site for the oxidation of fuel and a diffusion region (diffusion layer) composed of highly porous and electronically conductive material.
By taking into account the material balance for the water, its mass flux is given as 4 d w w I i j j F − = + (4) where 4 I i F − is the flux of the produced water mass and dwj represents the water flux entering the catalyst through the diffusion layer.
