Though comparing Canny operator and center B spline dyadic wavelet, the following conclusion is proven in this dissertation: a Center B spline function has tight support and Canny operator hasn't. b Center B spline function asymptotic convergence to Gaussian function and the derivative of Center B spline function asymptotic convergence to Canny operator. c The derivative of fourth order center spline B function is more suitable as a optimal edge detector than Canny operator. d Center B spline function can balance the smoothing and approximation of original data, and the fourth center B spline function is the only optimal solution of two order smoothing problem. e The error between the valve of time-frequency uncertainty of the fourth center B spline function and the lower bound of time-frequency uncertainty does not exceed 0.143% of the lower bound. f The derivative of center spline B function can construct a stability dyadic wavelet and can give a fast algorithm for multiscale edge detection, but Canny operator can do neither.
作者给出了Canny算子与中心B样条二进小波严格的比较证明,得出如下结论:a中心B样条函数具有紧支集,Canny算子不具有紧支集。b中心B样条函数的极限收敛于高斯函数,中心B样条函数的导数收敛于Canny算子。c四阶中心B样条函数的导数比Canny算子更接近最佳边缘检测滤波器。d中心B样条函数比高斯函数更能兼顾对原函数平滑和逼近的折中要求,并且四阶中心B样条函数是二阶逼近问题的唯一最优解。e四阶中心B样条函数的时频测不准关系值与时频测不准关系下界的逼近误差不超过0.143%。f中心B样条函数的导数可以构成稳定的二进小波,存在快速的多尺度算法;而Canny算子不构成稳定的二进小波,无法给出快速的多尺度算法。

In this paper, we construct the differential equation to solve the unconstrained optimization problem. Such methods solving the ill-conditioned problems are very effective. It indicates that the asymptotically stable region of explicit the Euler method to solve the differential equation equals to the descent region of the gradient method to solve the original unconstrained optimization problem.
我们发现,在用Euler方法求解二次优化问题的等价动力系统的方程时,由方法的步长确定的稳定区域对应于这些方法所得到的迭代公式的步长满足单调下降算法的条件确定的单调下降区域,因此我们可以利用这个性质构造解无约束优化问题的数值方法而不采用标准的常微分方程的数值求解公式。

Firstly, several kinds of schemes were proposed according to the design demand. The best scheme was chosen after analyzing and comparing the schemes. The robot's structure was designed with Pro/Engineer and AutoCAD software. Secondly, the kinematics analysis conducted, coordinate transformation matrix using D-H method was set up, and the kinematics equation direct solution and inverse solution was deduced. The manipulative interface about the kinematics equation direct solution and inverse solution was completed with VC++ and the velocity Jacobian of displacement matrix was constructed using differential transform method. In the process of the trajectory planning based on robot's kinematics analysis, I propone a method by which we can get middle nodal point with normalizing factor in order to simplify our searching for these middle nodal points. In addition, I give these middle nodal points with actual physics signification. For eliminating contradiction between real-time and accuracy, I bring forward separately limit of error and reversal interpolation method. For decreasing calculation quantity, we resort to tri-spline interpolation in the articulation space.We analyse the work range of the robot by resorting to graphic means.

That life comes with death is a fate common to all human beings One could observe the phenomenon of death but never understand its reality which explains why humans have had such a great fear of death Yet death remains a brutal fact after all and only with an adequate interpretation of it can human being face up to death The present dissertation is intended to explore ancient views on death in terms of three kinds of "life-seeking" attitudes: metaplasia resurrection and longetivity The primitives employed the collective myth-making to explain the riddle of death and create the belief in the "solidarity of life " Chuang-tzu accepted such a belief and developed in addition the idea of "qi" through his concept of "metamorphosis " In the period of Eastern Zhou it became popular to imagine dead people turning into ghosts and this brought out the idea of "soul " Yet is there another world after one dies?
有生必有死,是人类共同的命运。死亡的现象可以观察,但死亡的真相却是永远无解,因此人类害怕死亡。可是,死亡毕竟是一项事实,对它有所诠释,才能让人明白如何面对死亡。这篇论文希望探讨古人的死亡观,是以三种「求生」的态度:化生、复生,与长生,来进行讨论。原始人类集体创作神话来解释死亡谜团,透过「变形」此一律则,产生「生命一体化」的信念。庄子继承「生命一体化」的信念,他从「变形」的观念发展出「气」的观念,藉此说明他对於死亡的态度。东周时期,人死之后变成鬼的想法普遍流行,产生「魂魄」的说法。人死后是否会有另一个世界?

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.

I've never been to me hey lady, you, lady, cursing at your life you're a discontented mother and a regimented wife i've no doubt you dream about the things you'll never do but i wish someone had talked to me like i wanna talk to you i've been to georgia and california, anywhere i could run took the hand of a preachman and we made love in the sun but i ran out of places and friendly faces because i had to be free i've been to paradise, but i've never been to me please lady, please, lady, don't just walk away cause i have this need to tell you why i'm all alone today i can see so much of me still living in your eyes won't you share a part of a weary heart that has lived a million lies i've been to nice and the isle of greece while i sipped champagne on a yacht i moved like harlow in monte carlo and showed 'em what i've got i've been undressed by kings and i've seen some things that a woman ain't supposed to see i've been to paradise but i've never been to me hey, you know what paradise is?

First of all, the structure from the message, the message is divided into 3 parts: the first message, at the style, MAC address, so that packet transmission to reach the safety of the international financial sector standards; Secondly, the encryption method from the point of view, this The most prominent of the two systems were encrypted administrator password is encrypted on the card to encrypt passwords, especially for card encryption, the use of soft encryption service interface technology, using the work key, master key, the original password through the ciphertext key algorithm through two different DES encryption key to come up, we can imagine, I want to work at the same time key, master key, the text of the original secret password to a more difficult task, If the re-solution of the two DES, can be said to be completely impossible!
首先从报文结构上来看,报文分为3部分:报文头、报文体、MAC地址,使报文传输的安全性达到了国际金融行业的标准;其次,从加密方式来看,本次系统最突出的两个加密分别是对管理员密码进行加密、对卡密码进行加密,特别是对卡密码的加密,运用的是软加密服务接口技术,运用工作密钥,主密钥,原始密码通过算法得到密钥密文通过两次不同的DES加密才得出的密钥,可想而知,想要同时得到我的工作密钥,主密钥,原始密码密文本来就比较困难了,要是再解两次DES,可以说是完全不可能实现的!

That means you may find it is very difficult to tenderize the tough outer layer of lean meat on belly pork.
倘若要猪腩肉肥而不腻、入口即化,秘诀是切除猪腩肉的底层肉,原因在於现在的猪肉肉质有别於当年,尤其猪腩肉的底层肉特别难焖得软嫩,就算加长焖的时间,亦不能解此问题,只会将猪腩肉肥的部分煮融,瘦的部分仍然乾及硬,切除的底层肉可以留起放汤。
