There are two well-known shortcomings within K-Means algorithm prevailingly used in data clustering and other center-based clustering algorithms-the number of clusters must be known beforehand and the dependence of the algorithm performance on the initialization of the initial centers.

在聚类中广泛应用的K-Means算法及其它基于中心的聚类算法有两个共同的缺陷－需要预先确定类数目且随机初始化中心引起性能不稳定。

然后研究离散时间时延系统的鲁棒跟踪控制问题，通过求解一个LMI得到控制器的增益矩阵，进而使得闭环系统的状态变量渐近跟踪上任意预先设定的轨迹。

To redue the high computational inherent in the MAP detector, we apply an efficiency algorithm called the list sphere decoding.

另外，为了降低MAP侦测本身庞大的计算量，我们在MAP侦测前预先使用了list sphere decoding演算法，以降低在MIMO讯号侦测上的运算复杂度。

The central idea of the approach is "from idea to money", which accurately define the position of the expected benefits, analyze and design the process of benefit realization of benefits, including information system design, transform of organization structure, reorganization of work flow, enterprise culture reforger, stimulant system adjustment, at the same time, take the information system project as the same important project as the others, as a part of portfolio to be controlled according as risks and benefits. To promote every project and control the relative risk level, we need to set decision point named "stage gate", where we can evaluate the risks and benefits, then decide to enlarge or maintain or decrease or discard the investment. To ensure the promotion of the "Benefits Realization Approach", we must ensure the responsibility of the participator.

该途径的核心理念是&从概念到现金&，主要从全面管理、监控信息系统实施过程的角度出发，对信息系统预期利益进行准确定位，并对信息系统利益实现的过程进行预先分析和设计，内容涵盖了信息系统的设计以及必需的组织机构的变革、工作流程的重组、企业文化再造或调整、激励机制的调整；同时将信息系统投资视为与企业其他重大投资一样的投资项目，纳入企业的投资组合，进行风险利益分析与控制；为确保稳步推进各项目，并逐步控制风险，对项目实施过程设置了一系列决策节点，在此类节点上对项目的风险利益及现状进行评估，以决定是否加大投资、维持、减少还是撤消。

NO+NH3 temperature-programmed reaction runs over reduced catalyst samples pretreated with various oxidizing species showed that both NO2 and HNO3 were able to reoxidize the V catalyst at much lower temperature than gaseous O2: furthermore, they significantly enhanced the NO + NH3 reactivity below 250 C via the buildup of adsorbed nitrates, which act as a surface pool of oxidizing agents but are decomposed above that temperature.

不+NH3 温度-规划反应奔跑结束减少催化剂样品预先处理与各种不同的氧种表示两者的没有 2 和 HNO3 能够到再氧化 V 催化剂在非常低的温度超过气体的 O2：此外，他们重要地可提高的那不+ NH3 反应度在下面 250？C 经由组织吸附硝酸盐，哪一个行为当做一表面池氧代理人但是被分解上方哪一温度。
