Another direct take market as beginning point move to corporation , under this case , it , basing on the analysis on the optima ] number of business partners , argue that the forming of vc is the sharing result of transaction cost and incentive of non - contractible investment . at the last , base on the analysis mentioned above , and combining with the cases about clothing enterprise in wenzhou city of zhejiang province , it make suggestions to sems on what is the key factor to set up vc 另?个方向是以市场为起点,向企业方向发展,从这个角度本义以企业合作的最佳合作数量为研究对象,通过分析企业间协调成一本的以及参加虚拟企业的激励因索,提出虚拟企业的形成是交易成本和对商业伙伴的非和约投资进行激励两种因素共同作用的结果。最后,本文价:前} fll章节的从础卜,结合笔一者在温州对企业调研的案例,对中小企业运用虚拟企业这种组织形式提出建议。
The beginning point of the first research direction is that we design a type of load - balancing virtual topology which is insensitive to the traffic , such plan method has been proposed whose name is vlbs ( valiant load - balancing schemem ) , the disadvantage of vlbs is that it can only be applied to the homogeneous network in which each node has the same capacity , in chapter2 , a more general valiant load - balancing scheme ( gvlbs ) has been proposed , the advantage of the gvlbs is that it can be used both on the homogeneous network and heterogeous network , in this chapter , we will give the detail derivation process and numerical analysis . the beginning point of the second research direction is that we first design a virtual topology for the physical topology under a specific traffic matrix , for a while , the traffic has changed , the network performence will decline . under such condition , in chpater 3 , a virtual topology reconfiguration algorithm is studied which can decrease the average weighted hops 本文针对动态变化业务量情况下的wdm网络设计方法划分为两个主要的研究方向,第一个方向的研究出发点是可以在最初的虚拓扑设计过程中根据物理拓扑情况设计出一种虚拓扑出来,该虚拓扑是负载均衡的,在这种虚拓扑上跑的业务量矩阵特征只要在某种范围以内,无论它怎样动态变化,网络都不会出现拥塞,但这种虚拓扑设计算法vlbs的一个缺陷是它只能适用于同构网络,即每个节点所拥有的容量大小都相等,在第二章中,本文提出了一种更通用的负载均衡的光网络虚拓扑设计算法gvlbs ,该算法与传统的负载均衡算法vlbs不同之处在于vlbs算法只能适用于同构网络而gvlbs算法既可以适用于同构网络,又可以适用于异构网络,在本章中将给出了gvlbs算法的的详细推导和数值分析。
Based on the analyses , it was found that if the subsurface warm pool is regarded as the beginning point , the warm or cold signal propagates initially eastward and upward along the equatorial surface of msta to the eastern pacific and stays there several months and then turns north , usually moves westward near 10 to western pacific and finally propagates southward to return to warm pool to form an off - equator closed circuit . it takes about 2 to 4 years for the temperat ure anomaly to move around the cycle . if the smta of warm ( cold ) water is strong enough , there will be two successive el nino ( la nina ) events during the period of 2 to 4 years ) a事件下/负海温距平信号的分布和传播“轨迹” ,发现如果以暖池次表层为起点,则一般来说,暖水或冷水先是沿赤道的极值深度面向东、向上“传播”或运动,到达赤道东太平海盆边界附近后,分别转向向北和向南运动,然后在南、北纬10左右再折向西运动,并在暖池的经度范围内再作经向运动传到暖地,即在南、北半球以赤道为一边, “传播”或运动路径形成扁的闭合环路,温度距平运动一圈需时2 - 4年。
We believe that good faith is the philosophy in operation , reputation is the principle for seeking cooperation , technological progress is the initiative of development , and quality and efficiency is the beginning point for marketing all of these will help the company to become a first - class enterprise whichcan satisfy all our costomers 欣和骏公司深信:诚信是公司经营的宗旨,科技进步是公司发展的动力,高品质、高效率是公司产品投入市场的切入点,我们力争将公司在较短时间内成为让国内外客户信得过的优秀企业。
The main work completed in the paper is listed as following : 1 . image function acquisition - , 2 . read bmp files by dib format ; 3 . drawing gray scale histogram ; 4 . choose a optimum threshold and make gray image become binary image - , s . find image ' s contour points by making inner points become empty and apply template matching on the contour points ; 6 . transform the object ' s beginning points ( pixel point ) to the ones in the image coordinate and the positions of in the corresponding three dimensions ; 7 . compute the position vector and the normal vector of the object 选择一个最佳阕值,把灰度图像进行二值化处理; 5用掏空内部点法,找到图像的轮廓点,然后在轮廓点上进行模板匹配; 6把输出的目标物开始点(像素点)转化成图像坐标系中的点和对应的三维空间的坐标位置; 7计算目标物的位置矢量和法向矢量,根据机器人抓取面的法向矢量,找到机器人要抓取的平面; 8
