Methods A questionnaire survey was conducted among 194 diabetes patients and 129 close relatives of patients by random sampling. 方法随机抽样194名患者及其129名亲属进行问卷调查。
Close-Loop Identification Using Over-Sampling and its Estimate Accuracy Analysis 闭环系统的输出过采样辨识方法及其估计精度分析
The results of simulation in computer show that importance sampling technique results are close agree MonteCarlo method results. On the other hand, importance sampling simulation can significantly reduce the computational cost required by using Monte Carlo simulation when the BER is very low. 仿真结果表明,重要抽样技术仿真结果与蒙特卡罗方法仿真结果吻合得很好,并且在低误码率的情况下,与蒙特卡罗方法相比,重要抽样技术能显著降低运算量。
Tests showed that the average yield per mu obtained by typical mode sampling was more close to the average yield per mu actually measured in blank test than that obtained by random sampling. 试验结果表明,典型众数抽样较同时同地进行的随机抽样平均亩产量更接近空白试验所测得的每亩平均产量。
On the basis of theoretical analysis for the triangular carrier linear control, a new PWM arithmetic based on asymmetric regular sampling is brought forward, which is more close to natural sampling and easy to use on-line calculation method. 在分析三角载波线性控制原理的基础上,提出基于非对称规则采样的PWM计算方法。该方法比对称规则采样法更接近自然采样法,同时便于在线实时计算。
ASM samples signal with no strictly equal intervals in order that each sampling point is close to synchronous sampling point. 近似同步法采用了不严格相等的采样间隔,从而使每个采样点都尽量靠近同步采样点。
The research on fault soil gas and its application have been paid close attention by various countries in the world. However, the fault soil gas is obviously influenced by surrounding conditions, especially by the meteorological factors as a result of its shallower sampling depth. 断层土壤气的研究与应用已得到世界各国的广泛关注,但由于采样深度较浅,受环境条件特别是气象因素的影响较明显。
The model constructed in this way is very close to the final optimized one, thus Importance Sampling method is used to speed the estimation process. 由于初始模型的分布函数己经比较接近最优分布,应用Importance采样技术就可以极大的加快模型的学习过程。
