目的:本研究旨在客观测量体力活动以确定纵向轨迹;通过不同轨迹识别未知分组;检测社区居住女性中隐匿分组的关系。方法:研究样本包括来自"女性损伤研究"的669名女性。该研究是2007年在美国西南部中心地区进行的一项为期5年的前瞻性群组研究。研究将计步器连续18个月测得的计步数据拟合成一个隐匿发展模型和一个隐匿类型发展模型;对隐匿类型成员的基线特征进行回归分析。结果:体力活动的纵向变化随季节的转换很好地适应分段隐匿发展模型。在春、秋、冬季分别观察到体力活动水平明显提高和降低(p<0.001)。确定体力活动轨迹不同的3个隐匿分组:低活跃组(46.8%)、一般活跃组(41.3%)、活跃组(11.9%)。基线年龄和体脂百分比对低活跃组形成的可能性予以充分解释。结论:尽管可以确认女性体力活动的季节性变化,但变化并不明显。相对较大部分的样本显示女性体力活动长期处于低水平。对超重或肥胖以及年龄大于40岁的女性应进行适当干预,以提高其体力活动水平。

Evaluation of the k-nearest neighbor method for forecasting the influent characteristics of wastewater treatment plant

引用

Frontiers of Environmental Science & Engineering 2016年第2期10卷 299-310页

作者： minsoo KIM Yejin KIM Hyosoo KIM Wenhua PIAO Changwon KIM Department of Civil and Environmental Engineering Pusan National University Busan 609-735 Republic of Korea Department of Civil and Environmental Engineering Catholic University of Pusan Busan 609-757 Republic of Korea EnvironSoft Co. Ltd. #511 Industry-University Co.Bld. Pusan Nationai University Busan 609-735 Republic of Korea

The k-nearest neighbor （k-NN） method was evaluated to predict the influent flow rate and four water qualities, namely chemical oxygen demand （COD）, suspended solid （SS）, total nitrogen （T-N） and total phosphorus （T-P） at a wastewater treatment plant （WWTP）. The search range and approach for determining the number of nearest neighbors （NNs） under dry and wet weather conditions were initially optimized based on the root mean square error （RMSE）. The optimum search range for considering data size was one year. The square root-based （SR） approach was superior to the distance factor-based （DF） approach in determining the appropriate number of NNs. However, the results for both approaches varied slightly depending on the water quality and the weather conditions. The influent flow rate was accurately predicted within one standard deviation of measured values. Influent water qualities were well predicted with the mean absolute percentage error （MAPE） under both wet and dry weather conditions. For the seven-day prediction, the difference in predictive accuracy was less than 5% in dry weather conditions and slightly worse in wet weather conditions. Overall, the k-NN method was verified to be useful for predicting WWTP influent characteristics.

总氮检测作为城市污水处理的重要内容,是保证总氮去除、监督污水出水总氮含量的必要步骤。目前,我国大部分污水处理厂总氮检测主要依靠人工化验得到。测量和分析的频率为每周1-2次,很难依靠总氮的测量实时采取总氮的控制策略,进而导致出水总氮的监控严重不足,整体去除率不高,影响了污水处理厂运行效益,增加了对环境危害的风险。由于总氮受环境和其他污水过程因素的影响较大,出水总氮的含量也表现明显的波动,实现实时在线的总氮检测具有很大难度,现有的分析方法和仪表不能实时测量总氮浓度。因此,本论文提出了利用基于模糊神经网(FNN)的总氮软测量方法,预测总氮的浓度,具体如下:首先,设计了基于径向基函数神经网络(RBFNN)的模糊神经网络模型。其次,利用最小二乘法(Partial Least Squares,PLS)来选择与总氮相关性强的变量。然后,以所选变量为输入值对FNN模型进行训练。最后,在实际实验的基础上对模型进行了评价。同时,由于连接权值只存在于隐藏层和输出层之间,因此RBFNN难以表示非线性系统的输出。为了解决这一问题,提出的FNN模式将连接权值的种类扩展至多航式。另外,为了方便快捷地设计神经网的分段函数,还使用了模糊C均值(Fuzzy C-mean,FCM)聚类算法。实验结果表明,基于RBFNN的软测量方法可以快速测量总氮浓度。
