Its a Ellipse fitting algorithm for fitting Ellipses to a set of points in a image.

时间窗物流配送车辆路径问题(Vehicle Routing Prob- lem ,VRP)最早是由Dantzig 和 Ramser 于 1959 年首次 提出的.该问题的研究目标是 ,对一系列的顾客需求点 设计适当的路线 ,使车辆有序地通过,在满足一定的约 束条件(如货物需求量、发送量 、交发货时间、车辆容量 限制 、行驶里程限制 、时间限制等)下,达到一定的优化 目标(如里程最短、费用最少、时间尽量少、车队规模尽 量小 、车辆利用率高等).(With the development of diversified demand, the time demand of customers becomes more and more important in logistics distribution. Obviously, lowering distribution cost, distributing goods timely, improving the service quality, optimizing logistics distribution vehicle routing problem with Time Windows (VRPTW) is exigent to corporations.)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

ainsi permettre la simplification du calcul ultérieur des courants et tensions dans une partie de celui-ci. La méthode de Norton abouti invariablement au circuit suivant soit une source de courant, une résistance parallèle (correspond à la Ri de la source) et une résistance de charge. La résistance de charge est une des
