Investigation into pilot control model base on ANFIS for teleoperation rendezvous and docking 基于ANFIS的遥控交会对接先导控制模型研究
Yakun Zhang, Haiyang Li, Ruixue Huang
Handling qualities evaluation based on experimental investigation for system design and pilot behavior modeling may encounter bottlenecks for its inefficient and cost-consuming. To study the handling quality of teleoperation rendezvous and docking (RVD), a human model to describe the pilot control character during the final phase of teleoperation RVD is proposed in this paper. Twelve astronauts were chosen to conduct the teleoperation RVD experiments with different preliminary conditions. The pilot control model is built based on the adaptive neural fuzzy interface system (ANFIS) using the real experiment data to train and check. Validation experiment was conducted on the nine-degrees-of-freedom (9-DOF) teleoperation rendezvous and docking simulator (TRVDS) to check whether it can be used in fully numerical simulation. Simulation results indicate the pilot control model base on ANFIS can effectively emulate the pilot manual operation. Besides, the procedure of pilot control model could provide the designer a mean to preliminarily develop teleoperation RVD control system.
在系统设计和飞行员行为建模中,基于实验调查的处理质量评估由于效率低、成本高而遇到瓶颈。为了研究遥操作交会对接(RVD)的操纵质量,提出了一个描述遥操作交会对接最后阶段飞行员控制特性的人体模型。选择12名宇航员在不同的初始条件下进行遥操作RVD实验。基于自适应神经模糊接口系统(ANFIS),利用实际实验数据进行训练和检验,建立了先导控制模型。在九自由度遥操作交会对接模拟器(TRVDS)上进行验证实验,验证其是否能够完全用于数值模拟。仿真结果表明,基于ANFIS的飞行员控制模型能够有效地模拟飞行员的手动操作。此外,先导控制模型的建立为设计人员初步开发遥控遥控系统提供了手段。

You-Hong Li, Yin-wei Zhan, Xue-Jun Wang
At present in most field's data sets, spectral clustering community detection algorithm is difficult to predict the number of clustering problems, this paper proposes a community detection algorithm based on multi-domain adaptive spectral clustering (MDASC). Firstly based on the local node density composition, combined with graph edge-betweenness structural similarity matrix, normalized spectral clustering, got the biggest feature dimensions k value, so as to achieve the purpose of automatic identification number of the cluster, and finally re-use k-means classical clustering algorithm to cluster the feature vector space. Experiments show that compared with the traditional spectral clustering community detection algorithm, MDASC can construct a more efficient similarity matrix, simulation community structure is more close to the real, can adapt to all kinds of field sample data.
目前在大多数领域的数据集中,光谱聚类社团检测算法存在难以预测聚类数量的问题,本文提出了一种基于多域自适应光谱聚类(MDASC)的社团检测算法。首先基于局部节点密度组成,结合图边间结构相似度矩阵,进行归一化谱聚类,得到最大特征维数k值,从而达到自动识别聚类数的目的,最后再利用k-means经典聚类算法对特征向量空间进行聚类。实验表明,与传统的光谱聚类群落检测算法相比,MDASC能够构建更高效的相似矩阵,仿真群落结构更接近真实,能够适应各种野外样本数据。

A calculation simplified DPA attack based on reduced template 一种基于简化模板的DPA攻击算法
Xiaoyi Duan, Qi Cui, Sixiang Wang, Dongxu Li, Kewang Sun, Xianwei Gao
In a traditional template attack, during the template building phase, a large amount of calculation is usually needed, or, what is worse, some impossible calculation might be occurred to get the covariance matrix. Through a deep researching of template attack techniques, this paper has improved the template building method and proposed a new way which greatly simplified the template structure to avoid these problems. Also, we independently completed the development of a side channel power data acquisition platform and compiled the supporting side channel attack software. Targeting at the AES encryption algorithm implemented on a Mage16 single-chip board, we carried out a DPA attack based on template built by our method, the experimental results show that this method can effectively avoid the numerical problems that may be occurred in the traditional template attack, and compared to the ordinary DPA attacks the number of energy traces required by the attacks reduced substantially. It is strongly proved that the DPA attack based on our template is effective and practical.

Combined prediction method based on HHT of passenger volume of single inter-city train 基于HHT的单列城际列车客运量组合预测方法
Dongmei Zhou, Zhibin Zhang, Ge Meng
The prediction of passenger volume of single inter-city train is one of main basis for railway administrations to make scientific decisions, to make a feasible plan, to reduce the risk to the greatest extent, to reduce the operating cost and to make full use of the facilities. Because of the complicated and nonlinear relationship between factors that affect passenger volume, it is difficult to ensure the stability of the prediction results only by using the single predicting model and taking only some of the factors into consideration. The paper puts forward a combined prediction method based on the transform of HHT, and by using the historical data as the basis of the experiment, it also proves this method can reduce the volatility of the single forecasting model, realize the accurate prediction of passenger volume of single inter-city train, and effectively improve the reliability of the prediction results.
城际列车单列客运量预测是铁路管理部门进行科学决策、制定可行方案、最大程度降低风险、降低运营成本、充分利用设施的主要依据之一。由于影响客运量的因素之间存在复杂的非线性关系,仅采用单一的预测模型,仅考虑部分因素,难以保证预测结果的稳定性。本文提出了一种基于HHT变换的组合预测方法,并以历史数据作为实验基础,也证明了该方法可以减少单一预测模型的波动性,实现对单列城际列车客运量的准确预测,有效提高预测结果的可靠性。
