Abstract

Aiming at the mode mixing problem caused by interpolation point selection of conventional EMD (Empirical mode decomposition) method, a secondary iterative sifting EMD method that can avoid mode mixing and achieve high-precision decomposition of HHT (Hilbert–Huang transformation) is proposed based on the theory of EMD. The simulation results show that the proposed method is superior to conventional EMD on the ability to split mixed signal. Finally, the proposed algorithm is applied to the fault diagnosis of rolling bearing and the test results have proved its effectiveness and advantages.

Abstract

AC algorithm is a multi-pattern matching algorithm. And AC algorithm is often used in the snort system for feature detection. However, as the amount of data increases and the real-time requirements, AC algorithm needs to improve the efficiency of the algorithm. In this paper, we designed a parallelized AC algorithm. It uses the pipelining method to improve the efficiency of AC algorithm. This method is very effective in multicore environments. At the end of this paper, through experiments, we compared the running time and the speedup between classical AC algorithm and parallel AC algorithm.

Abstract

The anticorrosion performance and field application of a new rebar inhibitor were evaluated through the tests of half-cell potential and weight loss. The results indicated that half-cell potential of rebar had a negative shift with the addition of chloride ion, so it took long time to reach the stable potential. With the increase of chloride ion in the system, half-cell potential was more difficult to achieve stability. When chlorine ion content was low, inhibition effect was very obvious. Inhibition efficiency was 85.53% without chlorine ion and 85.74% with 1.0%NaCl by weight loss. New Rebar Inhibitor had no effect on the mechanical properties of concrete, which had good protective effect on concrete pipe rack in using.

37. Study on the Surface Quality of Al2O3 Nano-Films by Ion Beam Sputtering Deposition

Author

Lin, Xiao Ping, Dong, Yun, and Yang, Lian Wei

Abstract

The Al2O3 nano-films of different thicknesses (1~100nm) were successfully deposited on the monocrystalline Si surface by using ion beam sputtering deposition. The surface topography and the component of nano-films with different thickness were analyzed. The quality of the surface of nano-films was systematically studied. When the films’ thickness increase, the studies by atomic force microscope (AFM), X-ray photoelectron spectrum（XPS） show that the gathering grain continually grows up and transits from acerose cellula by two-dimensional growth to globularity by three-dimensional growth. The elements O, Al and Si were found on the surface of Al2O3 nano-films. With the thickness of the films increasing, the content of Al gradually increases and the intensity peak of Si wears off, the surface quality of the deposited films is ceaselessly improved
