IN this village everyone over 60 gets an old-age pension and farming is no longer the only way of making a living. People use ATM smart cards to draw out their wages, year-end bonus or stock market dividends. There are no "overnight millionaires" here and no abject poor. The village has trodden the road of prosperity for all. It is Caijiawa Village, in the mountainous Miyun County northeast of Beijing.

The dynamics for multi-link spatial flexible manipulator arms is investigated. The system considered here is an N-flexible-link manipulator driven by N DC-motors through N revolute flexiblejoints. The flexibility of each flexible joint is modeled as a linearly elastic torsional spring, and the mass of the joint is also considered. For the flexibility of the link, all of the stretching deformation, bending deformation and the torsional deformation are included. The complete governing equations of motion of the system are derived via the Lagrange equations. The nonlinear description of the deformation field of the flexible link is adopted in the dynamic modeling, and thus the dynamic stiffening effects are captured. Based on this model, a general-purpose software package for dynamic simulation of multi-link spatial flexible manipulator arms is developed. Several illustrative examples are given to validate the algorithm presented in this paper and to indicate that not only dynamic stiffening effects but also the flexibility of the structure has significant influence on the dynamic performance of the manipulator.

为了降低核仿射投影P范数(KAPP)算法的计算量和存储容量,提高在输入信号强相关时KAPP算法的收敛速度和稳态性能,该文提出基于高斯核显性映射的核归一化解相关APP(KNDAPP-GKEM)算法。该算法利用归一化解相关方法预先解除输入信号的相关性;利用高斯核显式映射方法近似得到显式核函数,消除了对历史数据的依赖,解决了KAPP算法因结构不断生长导致的计算量和存储容量过大的问题。α稳定分布噪声背景下的非线性系统辨识仿真结果表明,在输入信号强相关时KNDAPP-GKEM算法收敛速度快,非线性系统辨识稳态均方误差小,训练所需时间呈线性缓慢增长,有利于实际非线性系统辨识的应用。

本文针对策略型消费者网络购物问题,在考虑策略型消费者对产品估值不确定以及具有预期后悔行为下,研究了退货策略对消费者购买决策以及在线零售商运作决策的影响。以最大化在线零售商利润为目标,本文分别构建了退货策略与不退货策略下的利润模型。研究表明:消费者对产品估值的不确定性水平会降低零售商的利润,预期后悔会加剧零售商利润的降低;退货策略有利于缓解估值不确定与预期后悔对零售商的损害,且在退货策略下,消费者的预期后悔行为有利于增加零售商的利润。因此在线零售商的最优决策受产品匹配率以及高价值消费者比例的影响,无论零售商是否实施退货策略,零售价较低时市场完全覆盖下的最优订购量与最优利润并不总是优于零售价较高时市场部分覆盖策略下的,从而为在线零售商的退货略选择提供决策支持。
