Pattern formation in Rayleigh-Bénard convection: Numerical simulation with a coupled-map-lattice model

The various patterns formed in Rayleigh-Bénard convection under different conditions are numerically simulated with a coupled-map-lattice model. In the case of a lower aspect ratio (L/d=5), the simulations vividly depicted the main features of the transition process from a laminar state to a soft turbulence and then to a hard turbulence. In this case, the cellular structure in a horizontal section is also reproduced. In the case of a larger aspect ratio (L/d=30), the simulations successfully reproduced the spiral-defect chaos and target chaos in the initial stage of the pattern evolution which were recently found in experiments. In this case, for a fluid ofPr=1, it is verified in simulations that both the ideal straight rolls and spiral-defect chaos are stable attractors in the same parameter regime, and that the initial condition is a decisive factor for which one of the two is formed. In the same case, for a fluid ofPr=4, the target patterns are dominant instead of the spirals, the sizes and distributions of the target are also notably dependent on the initial condition.     

Stereo- and regio-selectivity in the photosensitized dimerization of 1, 3-dimethylthymine in solution

The effects of reaction pathway and temperature on stereo- and regio-selectivity of photocycloaddition of 1, 3-dimethylthymine (DMT) which gives four cyclobutane type dimers in solution using acetone as the photosensitizer, are investigated by measuring the product distribution. It is demonstrated that the ground-state aggregation between DMT molecules mainly leads to (h-t)dimers, and the diffusion-controlled triplet dimerization is favorable to the formation of (h-h) dimers.

复杂条件下的低渗透油田生产特征

在考虑了启动压力、毛管力、重力等因素的情况下 ,推导了低渗透油田油水两相渗流时含水率和无因次采油、采液指数的数学模型 ,并分析了上述 3种因素在数学模型中的作用。结果表明 ,对于水湿油藏 ,毛管力和启动压力的存在使含水率和无因次采液指数增加 ,重力则使无因次采液指数降低 ,而对含水率的影响与地层倾角有关。 3种因素均对无因次采油指数无影响。在理论分析的基础上 ,对胜利油区大芦湖低渗透油田的含水率和无因次采油、采液指数进行了实例计算 ,进一步验证了理论分析结果的可靠性     

Design and Implementation of a Novel Algorithm for Iterative Decoding of Product Codes

A novel product code iterative decoding algorithm and its high speed implementation scheme are proposed in this paper.Based on partial combination of selected columns of check matrix,the reduced-complexity syndrome decoding method is proposed to decode sub-codes of product code and deliver soft output information.So iterative decoding of product codes is possible.The fast sorting algorithm and a look-up method are proposed for high speed implementation of this algo-rithm.Compared to the conventional weighing iterative algorithm,the proposed algorithm has lower complexity while offering better performance,which is demonstrated by simulations and implementation analysis.The implementation scheme and verilog HDL simulation show that it is feasible to achieve high speed decoding with the proposed algorithm.
