简介:传统地形辅助导航适配区选择主要根据某一个地形特征参数的大小决定,因此不可避免地存在对地形适配性评判的不全面性。为了克服传统方法的缺点,提出了一种基于熵值法赋权灰色关联决策的地形辅助导航适配区选择方法,该方法综合考虑了地形标准差、粗糙度、地形高度熵及相关系数对适配区选择的影响。首先,利用计算得到的各特征参数值构建灰色决策矩阵;其次,对决策矩阵进行极差变换以及归一化处理得到灰色关联判断矩阵;最后,采用熵值赋权法客观计算各决策属性的权重,得到地形适配性综合评价指标。仿真结果表明,在评价值高的区域进行地形辅助导航,其匹配误差将更小。

简介:我们为f(T)严肃理论在宇宙论的限制的精确上探索SandageLoeb(SL)测试的影响。因为它在远类星体的系列在Lyman-森林里测量redshift飘移,SL测试是对当前的宇宙论的观察的重要补充,盖住2z的redshift沙漠5。避免数据矛盾,当模仿30的基准的模型嘲笑SL测试数据,我们基于当前的联合观察数据使用最好合适的模型。我们确定为f(T)严肃理论的参数评价上的这些SL测试数据的影响。二个典型f(T)模型被考虑,幂定律模型f(T)PL和指数形式的模型f(T)终止。结果证明SL测试罐头有效地打破存在在在另外的宇宙论的观察的今日的事密度m和小瘤常数H0之间的强壮的退化。为考虑f(T)模型,SL测试的30年的观察能极其改进m和H0的限制精确,但是不能有效地改进模型参数的限制精确。
