Intersections of Homogeneous Cantor Sets with Their Translations

引用

Acta Mathematica Sinica,English Series 2008年第8期24卷 1313-1318页

作者： mei Feng dai Nonlinear Scientific Research Center Faculty of Science Jiangsu University Zhenjiang 212013 P. R. China

We pursue the study on homogeneous Cantor sets with their translations. We get the fractal structure of intersection I（t）, and find that the Hausdorff measure of these sets forms a discrete spectrum whose non-zero values come only from shifting numbers with the coding of t. Concretely, a very brief calculation formula of the measure with the coding of t is given.

Based on the features of surfactant flooding, a mathematical model for surfactant flooding is established. The adsorption-retentlon, convection diffusion of surfactant and influence of concentration change upon relative permeability curve are included in the model. The novel description of adsorption quantity of surfaetant and relative permeability curve are presented, which enhance the coincidence between mathematical model and field practice, the relative errors of main development indexes arc within 6%. The model is applied to the numerical research of the surfactant flooding in the untabulated beds of Xingl-3 surfactant flooding pilot site of No. 4 Oil Production Company of Daqing Oilfield, the influences of surfaetant concentration, injection quantity, slug combination mode upon the development effect and economic benefit are quantitatively analyzed, the injection scheme is optimized as follows： surfaetant concentration is 0.5%, slug volume is 0.02 PV, slug combination mode is 2 slugs.

A PARALLEL NONOVERLAPPING DOMAIN DECOMPOSITION METHOD FOR STOKES PROBLEMS

引用

Journal of Computational Mathematics 2006年第2期24卷 209-224页

作者： mei-qun Jiang Pei-liang dai Department of Mathematics Suzhou university Suzhou 215006 China Department of Mathematics Changshu Institute of Technology Changshu 215500 China

A nonoverlapping domain decomposition iterative procedure is developed and analyzed for generalized Stokes problems and their finite element approximate problems in R^N（N=2,3）. The method is based on a mixed-type consistency condition with two parameters as a transmission condition together with a derivative-free transmission data updating technique on the artificial interfaces. The method can be applied to a general multi-subdomain decomposition and implemented on parallel machines with local simple communications naturally.
