Function,persistence, and selection: Generalizing the selected-effect account of function adequately

The selected effect account is regarded by many as one of the most attractive accounts of function. This account assumes that the function of a trait is what it has been selected for. Recently, it has been generalized by Justin Garson to include cases in which selection is understood as a simple sorting process, i.e., a selection process between entities that do not reproduce. However, once extended, this generalized selected effect account seems to ascribe functions to entities for which it looks unintuitive to do so. For instance, the hardness of rocks on a beach being differentially eroded by waves would be ascribed the function of resisting erosion. Garson provides one central argument why, despite appearance, one should not ascribe functions in cases of such sorting processes. In this paper, I start by presenting his argument, which hinges on whether a collection of entities form a population. I find it wanting. I argue instead that some selection processes are evolutionarily more or less interesting and that when a selection process is regarded as evolutionarily uninteresting, it will yield an uninteresting form of function rather than a reason for withholding the concept of function altogether.     

基于函数cot(x~α)变换的灰色GM(1,1)建模方法

提出了对建立GM(1,1)模型的标准化数据进行幂函数-三角函数cot(xα)(α>0)变换方法, 理论上证明了对原始数据序列进行这种函数变换可以有效地提高建模数据序列的光滑度, 且比"对数函数"法和"幂函数"法更加有效, 拓广了灰色模型的应用范围, 实例验证了所建GM(1,1)模型的精度优于"三角函数cot(x)"法所建模型, 说明了该方法的有效性.     

基于分段模糊Lyapunov函数的模糊系统分析与设计

在分析模糊系统前提规则结构信息的基础上,将模糊Lyapunov函数和分段Lyapunov函数结合,构造出一类连续模糊系统的分段模糊Lyapunov函数。采用并行分配补偿(PDC)结构,利用分段模糊Lyapunov函数进行了稳定性分析与控制律设计,得到了线性矩阵不等式(LMI)形式的连续系统镇定方法。该方法减少了模糊Lyapunov函数与分段Lyapunov函数的局限性,继承两者的优点,所得稳定性判据更为宽松,控制系统具有良好的控制性能。仿真实例表明了该方法的有效性。

一种基于函数S-粗集的态势预测方法

针对态势评估中未来可能出现态势的优劣情况,提出了一种基于函数S-粗集的态势预测方法。利用函数S-粗集的粗规律挖掘功能,采用拉格朗日插值多项式,以函数单向S-粗集对偶为例,给出了应用该方法的具体步骤。最后通过态势评估中一个具体实例证明了该方法的有效性。得到了运用函数S-粗集能够找到隐藏在系统中的粗规律的结论。     

基于需求层次理论的资本资产定价模型

将消费-投资者的需求层次心理特征对资产价格的影响纳入考察范围,本文建立了一个基于需求层次理论的资本资产定价模型（GCAPM）.证明了CAPM及APT只是该模型的一个特例.当消费-投资者只满足某一层次的需求时,该模型就简化为CAPM;当消费-投资者满足多重层次需求时,该模型从市场均衡及消费偏好的角度说明APT也是它的特例.与其他资本资产定价模型相比,这个理论能较好地解释红利溢价之迷.     

OPTIMAL SWITCHING AND IMPULSE CONTROLS FOR DISTRIBUTED PARAMETER SYSTEMS

Optimal switching and impulse controls for a distributed parameter systems are considered.We prove that the value functions u_u(·) of approximating problems approach to the value functionu(·) of the original problem,while u_u(·) is the unique viscosity solution of the correspondingHamilton-Jacobi-Bellman system.We also construct an optimal control for the original problem viathe value function u(·).
