As a result, there are no specific advantages of processing signals in frequency domain, and we propose to directly process signals in time domain. By this way, it is observed that in time domain the signal signatures can be arranged into groups of orthogonal components, leading to a very natural group-wise symbol recovery scheme. To realize this figure of merit, we propose a GSC-based receiver, which also takes into account the mitigation of channel mismatch effects caused by the channel temporal variation and the imperfect estimation.

因此，吾人提出直接於时域中处理讯号，於时域中，吾人发现讯号特徵矩阵能够被分为数个拥有正交元素的群组，能自然地被用来设计群组式讯号侦测技术，为了实现此特性吾人提出一个GSC接收机，其能同时抑制通道时间变化与通道估计错误所产生之通道偏差效应。

It is a feature that a sequence of orthogonal Ritz vectors is generated automatically based on the error minimization and employed to reduce the size of the system.

本文以典型的大跨圆拱屋盖为例，将里兹向量直接叠加法应用于屋盖系统特徵值问题计算和风致响应分析，其特点是在误差逼近的基础上自动生成一组正交的里兹向量幷用于缩减系统自由度数。

"It is far more sensitive than radiography for bone erosion in patients with early rheumatoid arthritis, and can detect pre-erosive features, such as osteitis and synovitis, along with tendonitis and potentially other MRI features that can be used to predict which patients will go on to severe destructive joint damage and irreversible functional disability," Dr.

Peterfy医师进一步指出，对於早期类风湿性关节炎病患而言，MRI在骨质糜烂的诊断上，远比X光摄影灵敏许多，且可侦测到糜烂前的特徵；像是骨炎与滑膜炎、连同肌腱炎与可用於预测严重破坏性关节损害及无法恢复的功能障碍，能一开始就向病患展现准确的预测，进行一个有效率的病患管理是非常重要的。

Overelaboration characterizes so much of presentday writing.
