  • 简介:这篇论文的目的,是调查能在银行兼并或获得的过程前后在时期期间被服务的内部审计和评估功能的必要性。在开始银行兼并或获得前后并且也的内部控制的功能内部听者是否作为必须被实现的那些认出考虑功能,被考虑。因此,我们形成了一张问询表,它因此是分布式的。获得的数据用描述的统计的方法被处理。结果记录他们能提供的值内部在银行兼并或获得的过程前后在阶段在一个公司的光滑的操作控制,并且根据他们的职业、文化的特征在内部事控制上反映听者的意见。

  • 简介:基于颤动的精力harvester是实质上在一个有限频率范围工作的一个共鸣器。增加工作频率范围是一个挑战性的问题。这份报纸为提高经由内部回声收获的精力揭示新奇可能性。内部回声精力harvester被建议。刺激连续地作为Gaussian白噪音,一个秒顺序过滤器定义的有颜色的噪音,狭窄乐队的噪音,和指数地相关的噪音被假定。相应平均root-mean-square产量电压被计算。数字结果证明内部回声增加操作带宽和产量电压。
