简介：AbstractCompletion thyroidectomy (CT) is employed after lobectomy when histopathological results mandates total removal of the gland as in case of well differentiated thyroid carcinoma (DTC). It is also employed as a second stage thyroid surgery when unfavorable events occur as in recurrent laryngeal nerve injury or when the surgeon finds out the case is beyond his/her expertise in an attempt to protect the contralateral side and allowing time for recovery or for an expert surgeon to help.

简介：为多重narrowbandfarfield的评价表明的direction-of-arrival(DOA)的一条途径被建议。这种技术使用一个新奇矩阵空间prefilteringapproach.Specifically，一个矩阵过滤器被设计空间地过滤到来的数据快照。从stopband到达的讨厌的部件尖部门被稀释，从兴趣的尖部门的需要的部件与最小的失真过去。矩阵过滤器空间地过滤元素空间数据，输出保留元素空间数据性质，它由在使用许多另外的数组处理器稀释干扰并且改进系统性能以前通过空间prefilter传递传感器数据使它很有用。DOA评价问题的几个例子被举说明建议空间prefiltering途径的表演。模拟和真实数据的结果证明预先过滤罐头高效地稀释空间干扰并且显著地为在通带部门内找到的消息提供者在低signal-to-noise比率改进评价和DOA评估者的决定能力。另外，空间prefilter的使用使多于一个数组的元素的数字为多重来源估计DOA可能。
