The paper analyses the relationships between the foreign reserves of china and the price index based on the cointegration method and vector error correction model of a variable vector auto - regressive ( var ) model 摘要本文運用多變量向量自回歸模型( var )的協(xié)整分析方法與向量誤差修正模型對我國外匯儲備與物價指數(shù)之間的關(guān)系進行了實證檢驗。
Chapter 3 : on the basis of chapter 1 , i present some new conceptions including distance function , distance membership function and fuzzy set of variable vector . then new fuzzy inference systems are constructed : nmamdani fis and nts fis 第三章:在第一章模糊理論的相關(guān)概念上,提出距離函數(shù)、距離隸屬函數(shù)和基于變量向量的模糊集合概念,并由此構(gòu)建了新型的模糊推理系統(tǒng): nmamdanifis和ntsfis 。
A variable vector propeller , called the " varivec propeller " , is under development as a new propulsion system for the undersea robot . the varivec propeller is a kind of specific propeller that is capable of continuously generating any degree of thrust in any three dimensional direction by varying blades " pitches cyclically in the process of rotation and responds easily to the slightest change in the robot 全方向推進器是一種在運動過程中螺距角可以變化的螺旋槳,該推進器是一種全新的設(shè)計,它最大特點是通過葉片螺距角在槳葉旋轉(zhuǎn)的過程中周期性的改變,產(chǎn)生前后、上下、左右六個方向的推力,并可以容易的對海洋機器人的微小運動作出反應(yīng)。
The proposed algorithms have good performances . some improvement on the gvf snake algorithm is presented to solve the problem of gvf snake ' s inability to converge to the rough contour of the brain . a variable vector field is designed and the constraint parameters of the gvf field is made adaptable to the target object features 本文的研究工作主要包括以下幾個方面:針對gvfsnake算法提取腦輪廓時不能很好的收斂于光滑性差的腦輪廓的問題,對gvfsnake算法進行了改進,構(gòu)建了一動態(tài)變化矢量場,把gvf場的約束權(quán)值設(shè)為隨目標特征自適應(yīng)變化,從而提出了一種新的算法,稱之為agvf ( adaptablegradientvectorflow ) snake 。
