A MULTIBLOCK PARTIAL LEAST SQUARES ALGORITHM FOR INVESTIGATING COMPLEX CHEMICAL SYSTEMS

The details of a general multiblock partial least squares(PLS)algorithm based on one originallypresented by Wold et al.have been developed and are completely presented.The algorithm can handlemost types of relationships between the blocks and constitutes a significant advancement in the modelingof complex chemical systems.The algorithm has been programmed in FORTRAN and has been testedon two simulated multiblock problems,a three-block and a five-block problem.The algorithm combinesthe score vectors for all blocks predicting a particular block into a new block.This new block is used topredict the predicted block in a manner analogous to the two-block PLS.In a similar manner if one blockpredicts more than one other block,the score vectors of all predicted blocks are combined to form a newblock,which is then predicted by the predictor block as in the two-block PLS.Blocks that both predictand are predicted are treated in such a way that both of these roles can be taken into account whencalculating interblock relationships.The results of numerical simulations indicate that the computerprogram is operating properly and that the multiblock PLS produces meaningful and consistent results.     

一种计算矿藏体积和储量的方法

本文使用一种随机模拟方法,把矿藏作为一个特定的封闭系统,以引起矿藏厚度或截面积变化的因果关系作最佳拟合,模拟计算矿藏体积和储量。同时,提供了该方法的数学模型,并编制了计算流程框图和BASlC程序。     

PROGRAM EVALUATION AS A STRATEGY FOR PROGRAM ENHANCEMENT

Formal program evaluation is one of the most widely used tools for program termination decisions in universities. By understanding and anticipating program evaluation, a farsighted geography department can convert it from a threat into a strategy for survival in the 1980s. In the process, many departments will be renewed and improved.

线性-动态规划改进模型及其应用

Becker和Yeh于1974年提出的线性(LP-DP)模型是一种功能很强的优化模型。然而该模型是针对梯级发电库群实时调度提出的,对并联系统并不适用。且该模型在理论上还不够严密,需进一步完善。本文所提出的LP-DP改进模型不但在理论上比较完整,而且扩展了应用范围,提高了优化效益。该模型现已成功地应用于江西省水火电力系统实时优化调度之中。     

水泥土搅拌桩复合地基的优化设计

运用双层地基模型的线弹性有限元程序对不同类型水泥土搅拌桩复合地基的沉降进行计算,分析了水泥土搅拌桩的桩长、置换率、桩身刚度对地基沉降的影响,同此确定了搅拌桩的有效桩长、最优置换率、最优桩身刚度。     

一种由微机控制的波浪数据采集系统

该波浪数据采集系统应用重力测波仪作传感器,由IBM—PC/XT微型计算机控制,将模拟信号经过A/D转换器进行波浪数据采集。采集到的数据按设计格式存入软盘,以便用处理程序进行统计和谱分析。本系统的数据采集程序在1987年9—11月西太平洋热带海域考察中得到应用,取得了较好的效果。
