Experimental Study on Dynamic Behaviors of Concrete Bridge in China Existing Railway Speed Increase to 200~250km/h Penghui Liu1, Yiqian Yang1, Jingchuan Yao1, Wei Wang1, Zhensheng Dong1 Railway Engineering Research Institute, China Academy of Railway Science, 100081 Beijing, China email: liupenghui@rails.com.cn, yangyiqian@rails.com.cn, yjcwxj@rails.com.cn, wangyawei5241@126.com, dzhsheng007@163.com KEY WORDS: Bridge; Dynamic Behaviors; Speed Increase.
Sometimes, a few light-weight abutments and flexible piers are used to reduce engineering quantity.
Because of the low speed early, which of the passenger train is less than 120km/h and the freight train is not ruled in design code with the operating speed of 60km/h, the bridge were designed to fulfill the requirement of ultimate capacity and save material.

Effect of Osmotic Pressure by Salt Concentration on Corrosion Resistance of Anti-Corrosive Paint Kyung-Man Moon1, Myung-Hoon Lee2,a* and Tae-Sil Baek3 1Dept. of Marine Equipment Engineering, Korea Maritime and Ocean University, Dong Sam-Dong,Yong Do-ku, Busan, Korea 2Dept. of Marine System Engineering, Korea Maritime and Ocean University, Dong Sam-Dong,Yong Do-ku, Busan, Korea 3Dept. of Steel Industry, Pohang College, Pohang City, Korea aleemh@kmou.ac.kr Keywords: Acid rain, Environmental contamination, Anti-corrosive paint, Impedance, Osmotic pressure, Salt concentration, Coated steel plate, Bare steel plate Abstract.
Experimental Procedure SS 400 steel with size of 30cm x 2cm x 0.3cm is prepared and cleaned with cleaning water for removing polluted material deposited on the surface, and then, removed oxide film by grinding blast cleaning method until surface profile is Sa 4.
As revealed in Table 3, corrosion current densities of all samples in the case of submerged in 0.1% and 9% NaCl solutions exhibited higher values compared to 3% NaCl solution.Thus, a large amount of chloride ion dissolved in 9% NaCl solution and higher osmotic pressure than 3% NaCl solutuon play a more key role in corrosion behavior of the coated steel compared to the bare steel.

Lead-bismuth cooled fast reactors are among important candidate of Gen IV NPP which have inherent/passive safety feature, ability to utilize uranium much more efficient compared to the LWR, non-proliferation resistance, and economical.[8-12] The key strategy to achieve inherent safety capability for fast reactors generally by minimizing excess reactivity to avoid super prompt critical accident or unprotected rod run-out transient overpower (UTOP) accident[5,7,8,10], optimizing natural circulation component to anticipate unprotected loss of flow (ULOF) accident, optimizing the reactivity feedback to maximize safety margin during severe accident[5,7,8,10].
These behavior are strongly related to the high burnup material in the case C which can reach more than 38% HM at the disposal time.

Figure 1 shows the key features of the diamond stick for the rubbing experiment [5].
Material properties of the diamond stick and the cobalt-free tungsten carbide (CW500, Dijet Co.) are shown in Table 1.
In the rubbing experiment, lubricants are sprayed on the tungsten-carbide surface using a MQL (minimum quantity of lubrication) system (Fuji BC Engineering, FK1-M-LM).

Information Processing with Combination Method for Dependent Evidences Based on Principal Component Analysis Jie Yao, Tao Hu, JianJun Yang （Dept. of Management Science, Naval Univ. of Engineering, Wuhan 430033, China） Key words: evidence theory; dependent evidence; PCA; evidence combination Abstract: To meet the requirement that evidences must be independent for evidences combination in D-S evidence theory when the information processing, the dependence among evidences should be eliminated, so a new combination method of dependent evidences based on the Principal Component Analysis (PCA) is presented.
Evidence Theory and Evidence Dependence Concepts in Evidence Theory In evidence theory, evidence is not any physical material, but a form of knowledge and experience and the result of observation and research regarding any specific issue.
