This study was conducted to examine the interrelationship of 10 seed vigor traits in 12 wheat genotypes through variance, co - variance and path coefficient analysis, to determine broad - sense heritability, and to estimate genetic advance under selection. the genotypes showed significant difference for all traits, except for percentage of normal seedling. genetic correlation between conversion efficiency of seed reserve, electrical conductivity with other traits were not significant, showed that selection for any of them might be possible without hampering any other traits. however path coefficient analysis indicated that conversion efficiency of seed reserve, seed reserve utilization ratio have strong direct effect in affecting seedling weight, and that mean germination time has significantly negatively correlated in affecting gi. moderate to high estimates of broad - sense heritability, genetic coefficient of variation and expected genetic advance were obtained for electrical conductivity, germination index, mean germination time, seed dry weigh, seedling dry weigh, seed reserve depletion ratio indicating the possibility for improving these traits

  8. Control systems in modern automatic engineering are nonlinear, time - changed and indefinite. lt is difficult to model by traditional method, even sometime impossible. under these circumstances we should apply model identification to gain the approximate model of object for effective control, there are many models to be chosen, fuzzy model is one of them, it is put forward with the development of fuzzy control. fuzzy model has characteristics of general approximation and strong nonlinear, it is fit for describing complex, nonlinear systems. to avoid rules expansion when the number of input values are very big. in this paper we apply hierarchical fuzzy model to resolve this problem, we also illustrate it has general approximation to any nonlinear systems. genetic algorithm is a algorithm to help find the best parameters of process. lt has abilities of global optimizing and implicit parallel, it can be generally used for all applications. in our paper we use fuzzy model as predictive model and apply ga to identify fuzzy model ( including hierarchical fuzzy model ), we made experiments to nonlinear predictive systems and got very good results. the paper contains chapters as below : chapter 1 preface

    現代控制工程中的統多表現為非線性、時變和不確性,採用統的建模方法比較困難,或者根本無法實現,在這種情況下,要實現有效的控制,必須採用模型辨識的方法來獲取對象的近似模型,並加以控制,目前用於統辨識的模型種類很多,模糊模型是其中的一種,它隨著模糊控制的發展而被人提出,模糊模型具有萬能逼近和強非線性的特點,比較適合於描述復雜非線性統,為了解模糊模型在輸入變量較多時規則膨脹的問題,文中引入遞階型模糊模型,並引證這種結構的通用逼近特性。演算法是模擬自然界生物進化「優勝劣汰」原理的一種參尋優演算法,它具有隱含并行性和全局最優化的能力,並且對尋優對象的要求比較低,在工程應用和科學研究中,得到了廣泛的應用,本文將演算法引入模糊模型的辨識,取得了很好的效果。
