简介：瞄准underdeterminedconvolutive混合模型，一个盲目讲话来源分离方法基于掩盖的非线性的时间频率被建议，在在在时间频率领域的独立讲话信号之中的近似W拆散orthogonality(W做)性质被利用的地方。在这个方法，从multimicrophones的观察混合信号被使正常化起初独立于在时间频率域的频率，然后，动态聚类算法被采用在每时间频率槽获得积极来源信息，经由从簇中心的偏转角度的一个非线性的函数为掩盖的时间频率被选择，最后，混合讲话信号的盲目分离能被反的STFT(短时间的Fourier转变)完成。这个方法不能仅仅解决可以在很经典的频率域窗帘分离技术被遇见的频率排列的问题，而且压制分离矩阵的空间方向散开。模拟结果证明建议分离方法比典型蓝色方法好，signal-noise-ratio获得(SNRG)平均增加1.58dB。

简介：直接模拟蒙特卡罗(DSMC)方法被介绍在多部件气体混合物为声学的繁殖建模。并且声学的变细的一个理论预兆的模型被建议，它不依靠经验的参数。各种各样的多部件气体混合物的声学的变细系列，由氮，氧，二氧化碳，甲烷和水组成，被DSMC方法估计。兴趣的健全频率范围从8MHz到232MHz。与基于DL，加古典变细的模型由Stokes-Kirchhoff公式计算了的松驰变细的结果相比，我们的模型的声学的变细的评价同意了他们。模型的精确取决于变细从产生的分子碰撞的物理机制的理解。另外，我们的模型的结果证明频率依赖者的人物声学的变细依靠煤气的混合物的作文。并且这能导致能够在各种各样的环境和进程决定煤气的作文的份量上的聪明的声学的煤气的传感器的开发。
