New algorithm of mine slope reliability based on limiting state hyper-plane and its engineering applicationLIU Zhi-xiang(刘志祥), TANG Zhi-xiang(唐志祥), WANG Wei-hua(王卫华), SUN Jing-jing(孙晶晶), PENG Kang(彭... reliability based on limiting state hyper-plane is proposed. It is shown that by using this new reliability algorithm the calculation of partial derivative of performance function is avoided......
Retraction control of motorized seat belt system with linear state observerLee Kang-seok, Choi Chin-chul, Lee Woo-taik(Department of Control and Instrumentation Engineering, Changwon National University, Changwon 641-773, Korea)Abstract:a design and verification of linear state observers which estimate state information such as angular velocity and load torque for retraction control......
Effect of TiB2 addition on microstructure of spray-formed Si-30Al composite GAN Gui-sheng1, 2, ZHANG Lei1, BEI Shu-yu1, LU Yi1, YANG Bin1 1. State Key Laboratory for Advanced Metals... that adding 2% TiB2 to the Si-30Al alloy can effectively refine the primary Si. Moreover, the coarsening and growth of primary Si phase in its semi-solid state was retarded effectively due......

observation, in which solid solution and the as-aged state of each alloy were compared to discuss the influence mechanism of lead and aluminium on the electrochemical properties of alloys. The X-ray... solid solution and the as-aged state demonstrates that Mg2Pb and Mg17Al12 somewhat increase corrosion resistance but lighten anodic polarization by facilitating corrosion product flaking off. Key words......
Microstructural evolution of NiFe2O4-10NiO powder prepared by high temperature solid state reaction ZHANG Lei(张 雷), ZHOU Ke-chao(周科朝), LI Zhi-you(李志友), YANG Wen-jie(杨文杰) State Key Laboratory... was prepared by high temperature solid state reaction. The microstructural evolution from the raw materials NiO and Fe2O3 to the NiFe2O4-10NiO powder was studied by SEM. The results show that the domain......
