An Improved S-Random Interleaver Design for Turbo Code Based on Chaos Model

A new method to design interleaver based on Henon chaos model is presented. The designed interleaver is with rather random behavior. Experimental results show that the proposed S-henon interleaver make a magnitude of im provement in bit error rate （BER） performance by 0.4 dB compared with the S-random interleaver for AWGN channel respectively. The S-henon interleaver may be adapted to 3G mobile communication systems.

对MXA-300型采煤机调高系统的技术改造

MXA—300型采煤机在工作一定年限后，其液压系统的完好性、密封性、灵敏性、可靠性降低。由于以上原因造成采煤机调高系统内双锁阀关闭不严，使微量油液泄漏，导致机组在运行过程中摇臂出现下滑、自落现象，严重制约工作面正常生产。针对这种情况，王庄煤矿曾在6105工作面使用DSF型单项锁对MXA—300型采煤机的调高系统进行了改造，收到了良好效果，为工作面正常生产创造了有利条件。     

自适应冗余第2代小波设计及齿轮箱故障特征提取

针对强噪声背景下齿轮箱故障特征的提取问题,设计了一种提取该类信号时域特征的自适应冗余第2代小波.采用基于数据的优化算法设计每层小波分解的初始预测器和更新器,然后通过对初始预测器和更新器进行插值补零运算,来获得冗余预测器和更新器.第2代小波不需要剖分运算,利用冗余预测器和更新器直接对每层逼近信号进行预测和更新运算,能较好地保留信号的时域特征.采用第2代小波较理想地提取出了齿轮箱发生摩擦故障时的时域调制波形和周期性冲击脉冲,并对得到的细节和逼近信号进一步进行包络解调,从而分离出了故障调制源频率.结果表明,自适应冗余第2代小波对噪声背景下齿轮箱故障特征的提取效果优于其他小波.

Genetic analysis of segregation distortion of mating-type factors in Lentinula edodes

Analyses of the mating-type ratio of protoplast monokaryons to spores in 28 strains of Lentinula edodes were performed through statistical methods. The results showed that the segregation distortion phenomenon commonly exists in both types of Lentinula edodes, 17 out of the 28 samples did not display the expected 1∶1 ratio of protoplast monokaryons; and among them 8 fruiting strains distorted 1∶1∶1∶1 segregation of spores. The degree of distortion in all tested wild strains was significantly lower than that of cultured strains. In fruiting test of positive-negative parent, predominant spores were those with the mating type identical to dikaryotic parent, indicating that the predominance of nuclei mainly depends on the mating type of dikaryotic parent. Data from di-mon mating test verified that monokaryons with acceptor nuclear type are present exclusively in a large amount after dedikaryotization, suggesting that the specificities among B factors and some other unknown factors in cytoplasm are probably responsible for the phenomenon of skewed segregation.

Novel Hyper-Redundant Manipulator-. Design, Study and Experiment

A novel hyper-redundant manipulator named RT1 is designed and studied. The unique feature of RT1 is all degrees of freedom (DOF) are actuated with only one motor via special designed hinge bar universal joints. The mechanisms of RT1 are introduced in detail. Some experiments are carried out in order to test the movability and adaptability of the manipulator. RT1 is actuated by pulse string and acts discretely. The discrete working space of RT1 is described and the parameter optimization for kinematical redundancy resolution is studied also. The optimization criterion is altering the design parameter as little as possible during manipulator's motion from the initial position to the expected position. An optimization example is given that is realized with Matlab optimize tool-box.
