An approach about large dynamic programming based on discrete linear system with a quadratic index function is proposed by importing two Lagrange multipliers.     

综合评判的神经网络方法

综合评判的方法已经广泛运用到信息，决策，管理和控制等领域，但是它的两大难点－权重和单因素评价矩阵的确定越来越来明显地展现在人们面前，本文试图用神经网络方法来解决这两个难点，并从理论上证明了这种方法的收敛性。     

The young adult patient

The purpose of this paper is to 1) describe the unique issues of voice patients, ages 21–55; 2) outline the knowledge and clinical skills that speech language pathologists should possess to deal with those issues; and 3) provide suggestions for promoting vocal longevity.     

The impulse influence function for de-centralized control

Impulse influence matrix function is introduced based on that the de-centralized control analysis is analogous to the sub-structural analysis in structural mechanics. The static sub-structural analysis is analogous to the usual de-centralized control, whereas the dynamic sub-structural analysis corresponds to the de-centralized control theory. The re-     

Intensity range as a function of task and training

This study examined intensity range as a function of elicitation task (reading and automatic speech sequences), musical training, and the interaction between task and musical training in 31 college students. The results indicated significant differences in loudness range by experiental task. Intensity range for the descending automatic sequence was significantly greater than that for the ascending and reading tasks. While the overall effect of musical training was nonsignificant, there was a significant interaction between task and training, with musicians having a significantly greater mean range on the ascending task. A comparison between ascending and descending tasks indicated a significant mean difference between lower limits and no significant mean difference between upper limits. The range for the reading probe was located approximately in the middle of the total available intensity range.

长途汽车运输调度专家系绕

本文描述了一个汽车运输调度专家系统,该系统根据调度员的经验,将当天的运输业务划分成子业务集,用空载最优算法确定子业务集中的最佳运输路线,得到局部解,再由局部解求得全局最优解,达到提高长途汽车运输的里程利用率的目的。     

模糊识别模式在粉土液化判别中的应用

基于模糊数学的基本原理和方法,分析了粉土液化的影响因素,选取粉土的平均粒径,相对密度,标准贯入击数和上覆有效压力作为评价指标,构造粉土液化的模糊识别模式。验证和应用结果表明,模糊识别模式具有很好的映射能力,是粉土液化势预测的有效手段。     

地下与露天复合采动影响下边坡岩体稳定性评价方法的研究

矿产资源的开采, 有些是按地下与露天复合开采方式进行。依据采区的空间对应关系, 两种采动影响域中的一部分相互重叠, 导致采动效应相互作用和相互叠加, 从而组成一个复合动态系统, 因此边坡岩体变形机理更加复杂, 与单一露天开采相比有较大的差异；然而, 过去在处理此类问题时近似地应用单一露天采动影响下的分析方法, 结果与实际情况存在一定差异；本文在理论分析的基础上, 推导出边坡稳定性的评价方法, 为此类矿山后续采矿设计及安全生产提供科学依据。
