The theory of Pansystems Multionomial forecasting (TPMF) is a theory which researches this kind of multinomial forecasting problem:Suppose S(t) is an undnown multinomial, S(j) is the value vector of S(t) at t=t_j. If we get a set of data(S_0, S_1,…, S_n), S_j is an approximate vector of the vector S(j), then how to forecast the vector S(n+1) and what is the maximum of the distance between the forecasting vector and the vector S(n+1) under the condition that S(t) unchanges during the discussion procedure and the range of error is knowm.The purpose of the paper is to give a brief introduction of TPMF.  相似文献

Before the present of basic model,one example is given in section 2 to illustrate the economic intuition behind the SSE. The general model,including the three hypotheses,adaptive play setting and basic results is laid out in section 3. Sections 4 study the asymptotic behavior of this model. This review concludes with a comment.  相似文献

1 Results On the basis of previous work,the general theory,least square methods and computing programs have been proposed and developed,which can separate the two-fold broadening effect caused by crystallite-micro strain,crystallite-stacking faults,strain-faults and which can also separate the three fold broadening effect caused by crystallite-strain-faults in closed-parked hexagonal (CPH) nano-materials.The method is applied to characterize and investigate the microstructure in β-Ni(OH)2 as negative material for nickel/metal (Ni /MH) batteries.The results indicate that in the raw β-Ni(OH)2 there are only two-fold broadening effect of crystallite-faults,however after activation and cycle test three fold broadening effect of crystallite-strain-faults is available.  相似文献

Agricultural eco-engineering is not only the important content of eco-agriculture construction, but also the important measure for operating eco-agriculture construction. Applying principle of ecology, and combining the method of systemic engineering with the measure of modem technology, the essential of agriculture ecologic engineering is to build the production mode of using agriculture resource with high effectiveness, and technique system of realizing sustainable development. This article gives an introduction of what the agricultural eco-engineering is and the basic theory and the design principle of agricultural eco-engineering.  相似文献

The controller designed according to classical or modern control theory will not satisfy the performance requirements when the controlled object in industrial field can not be described by exact mathematical model or the disturbance of the controlled system. In order to make the controlled system stable and having good performance, H∞ control theory was put forward to solve this practical problem. Taking the position of a rolling mill as the controlled object, it was rectified by optimal engineering way. Then, three different plans were put forward according to Bang-Bang control, LQ control and H∞ control, respectively. The result of the simulation shows that the controller designed according to H∞ method whose robust performance and ability to restrain colors disturbance is satisfactory.  相似文献

全息图像实验的噪声及衍射效率   总被引:1,自引:0,他引:1  
全面地讨论全息噪声产生的各种来源和抑制办法。在拍摄全息时,一般总希望提高衍射效率,但应依据拍摄对象来源来选择参物比,以求得总的衍射效率和整体效果最佳。在考虑到外部环境的影响时,拍摄时间不宜过长。在一定的条件下,为了获得最佳的效果,存在着一个最佳曝光时间的问题。在电镜观察下,记录材料的分辨率不够时,干涉条纹的信息将破坏。  相似文献
