简介:the account holder can only withdraw monthly a certain percentage of his last drawn salary. He can also be allowed to withdraw his CPF savings for a period that is limited to six months or a year. The CPF Board must be satisfied that the applicant has truly been retrenched by his employer,they would dream of owning a car or a house. There is an even greater number of Singaporeans who do not see the need to save because they are already contributing to the CPF. I,可能是双收入的家庭少了一个收入来源
简介:allowed to withdraw his CPF savings for a period that is, The CPF started off as a savings scheme for old age.,encourage the unemployed to look for a job. So we have to be
简介:惯导固有原因使得载体长时间航行累积大量误差.可通过重力梯度量测与惯导组合导航方法来修正导航误差.先对重力梯度仪与惯导组合导航原理进行阐述,提出重力梯度仪辅助INS(GAINS)的系统框架图,对导航用重力梯度图和重力梯度仪进行分析,设定组合量测方程.然后根据状态空间方程的特点,提出使用边缘Cubature粒子滤波(CPF)进行融合估值.通过理论方法证明其对方差的减小,同时给出算法流程.相同条件下与已有APO-PF算法仿真进行经纬度RMSE结果对比,表明该算法估值精度更高;并用CEP对导航误差研究,得到在性能较低的惯导条件下、在梯度仪1E2和10E2噪声下4h的CEP数值分别为0.044nmile和0.072nmile的结果.最后对状态方程简化,定性分析出其余状态量的估值效果.
