查询词典 selection

We introduce the general sigma point selection framework, and give two kinds of efficient methods: a reducing the computing complexity by decreasing the number of the sigma point; b scaling the sigma points to influence the effects of the higher order moments, then improve the accuracy of the UT; c Convergence analysis of the UKF, when used as an observer for nonlinear deterministic discrete-time system, is presented. Based on the UKF that captures the posterior mean and covariance accurately to the second or third order term (in terms of Taylor series expansion) for any form of nonlinearity, sufficient conditions to ensure local asymptotic convergence are established.

论文介绍了sigma点的一般选取规则，并给出了两种有效的方法：a通过减少sigma点集合的元素的数目来减少计算复杂度，b通过增加参数来逼近泰勒展开的高阶项，从而提高UT变换的精度；c论文研究了UKF算法应用于非线性确定性离散时间系统时的收敛性问题。

In order to implement PSSLC comprehensively,the following goalsmust be achieved.First we must specify that PSSLC is the fundamental target of thedevelopment of our CSAS,and that the choice of appointed and selected leading cadresbelow the rank of vice-minister must be brought into the field of the system.Thus it willhelp to accelerate the transition process of the system and to form at soonest the new CSASpattern with PSSLC as principle part coordinated by other CSAS including the system oftaking position through competition and recommendation-appointment system.Second wemust modify＜The Provisional Regulations for national Public Servant＞and＜TheProvisional Regulations for the work of Selection and Appointment of Party andGovernment cadres＞and improve reserve cadres institution and other relative institutionsto adapt PSSLC.We must found a necessary examination management organization forPSSLC to provide an organizational guarantee for the overall implementation of PSSLC.

要全面推行公开选拔领导干部制度，必须明确该项制度是我国干部选拔任用制度发展的主体目标，把副部级以下委任制领导干部和选任制领导干部人选纳入公开选拔的范围，加速干部选拔任用制度的转轨进程，以早日形成以公开选拔领导干部制度为主体，以竞争上岗制和荐举委任制等干部选拔任用制度为配套的干部选拔任用的新格局；必须修改《国家公务员暂行条例》《党政领导干部选拔任用工作暂行条例》并完善后备干部制度等相关制度，以使之与公开选拔领导干部制度衔接与配套；必须建立相应的公开选拔领导干部考试管理机构，为全面推行公开选拔领导干部制度提供坚强有力的组织保障。

Simulation results show that, for the fixed sampling frequency, the error rises with the frequency increasing of periodic signal, and decreases with the attenuation time constant increasing of non-periodic signal. The sampling frequency determines the upper limit of appropriate frequency band directly. The research provides the basis for the selection of cutoff frequency in filter design.
