一种基于预测滤波器的自适应卡尔曼滤波算法

针对系统过程噪声统计特性不确切或未知的条件下,研究了一种基于预测滤波器的自适应卡尔曼滤波算法。由预测滤波器实时估计系统模型误差及其协方差矩阵,再用其修正系统状态预测值及预测误差协方差矩阵,从而自适应调节卡尔曼增益。将该算法应用于弹载SINS/GPS紧耦合组合导航系统并与普通卡尔曼滤波、基于新息的移动开窗自适应卡尔曼滤波进行了对比,仿真结果说明该自适应滤波算法具有更高的可靠性和精度。

Layers of Experiments with Adaptive Combined Design

In the field of nanofabrication, engineers often face unique challenges in resource‐limited experimental budgets, the sensitive nature of process behavior with respect to controllable variables, and highly demanding tolerance requirements. To effectively overcome these challenges, this article proposes a methodology for a sequential design of experiments through batches of experimental runs, aptly named Layers of Experiments with Adaptive Combined Design (LoE/ACD). In higher layers, where process behavior is less understood, experimental regions cover more design space and data points are more spread out. In lower layers, experimental regions are more focused to improve understanding of process sensitivities in a local, data‐rich environment. The experimental design is a combination of a space‐filling and an optimal design with a tuning parameter that is dependent on the amount of information accumulated over the various layers. The proposed LoE/ACD method is applied to optimize a carbon dioxide (epet‐CO2) assisted deposition process for fabricating silver nanoparticles with pressure and temperature variables. © 2015 Wiley Periodicals, Inc.

登步岛渡海登陆作战经过与思考

1949年10月下旬至11月上旬,中国人民解放军在华东闽、浙沿海有两次激烈的渡海攻占敌岛的战斗,这就是金门岛战斗和登步岛战斗.金门岛进攻作战,系第三野战军第10兵团第28军和第29军各一部登陆金门岛,与国民党军3万余人激战两昼夜,两批登岛部队3个半团9086人,因后援不继,全部覆没.     

Alleviating time inconsistent behaviors via a competition scheme

Under quasi‐hyperbolic discounting, the valuation of a payoff falls relatively rapidly for earlier delay periods, but then falls more slowly for longer delay periods. When the salespersons with quasi‐hyperbolic discounting consider the product sale problem, they would exert less effort than their early plan, thus resulting in losses of future profit. We propose a winner‐takes‐all competition to alleviate the above time inconsistent behaviors of the salespersons, and allow the company to maximize its revenue by choosing an optimal bonus. To evaluate the effects of the competition scheme, we define the group time inconsistency degree of the salespersons, which measures the consequence of time inconsistent behaviors, and two welfare measures, the group welfare of the salespersons and the company revenue. We show that the competition always improves the group welfare and the company revenue as long as the company chooses to run the competition in the first place. However, the effect on group time inconsistency degree is mixed. When the optimal bonus is moderate (extreme high), the competition motivates (over‐motivates) the salesperson to work hard, thus alleviates (worsens) the time inconsistent behaviors. © 2017 Wiley Periodicals, Inc.
