Applying the De Caen"s inequality of sum of the squares of the degree and Cauchy"s inequality, we obtain a strict lower bound and a strict upper bound of the largest Laplace eigenvalues only in terms of vertex number of a unicycle graph. Applying the Laplace matrix theorem of trees, we obtain an upper bound of the second smallest Laplace eigenvalues of a unicycle. Extremal graph whose second smallest Laplace eigenvalues reach the obtained upper bound is determined. We also obtain an upper bound of the second largest Laplace eigenvalues in terms of vertex number of the largest connected branch of unicycle graph, and obtain a theoretical method to calculate the second largest Laplace eigenvalues of unicycle graph. We obtain an upper bound of any Laplace eigenvalues in terms of vertex number of a unicycle graph. We also obtain the distribution of Laplace eigenvalues in the inter [0,n] in terms of the matching number.

Coco Palm is let down by mainly 2 things...the staff and the food....the staff are rude, unhelpful and really just dont look like they want to be there...every encounter we had with them they did not provide anything close to the 5 star standards we expect.....the horror started for us when we arrived at Male airport to be told we had to wait an hour for another flight to come in before we could be transferred to the island THIS IS NOT 5 STAR STANDARD I rang the resort adn expressed my concerns only to be laughed at by someone on reception THIS IS NOT 5 STAR SERVICE..

波杜希蒂岛度假村主要有两方面让我们失望。。。员工和食物。。。员工没有礼貌，又不帮助人，让人真得感觉他们不像是这儿的人。。。我们遇到的每一件事他们都不给我们提供我们所期待的接近五星级标准的服务。。。。从到达马累机场起我们就开始遭殃了，因为一到达机场就有人告诉我们在被转送到岛上之前，我们要等一个小时才有另一架飞机来接我们，这不是五星级的标准，我给度假村打电话，表达了我的担忧，却被前台的某些人嘲笑，这不是五星级的标准。。。。

In this paper, we introduce the algorithm of Schoof-Elkies-Atkin to compute the order of elliptic curves over finite fields. We give out a fast algorithm to compute the division polynomial f〓 and a primitive point of order 2〓. This paper also gives an improved algorithm in computing elliptic curve scalar multiplication. Using the method of complex multiplication, we find good elliptic curves for use in cryptosystems, and implemented ElGamal public-key scheme based on elliptic curves. As a co-product, we also realized the algorithm to determine primes using Goldwasser-Kilian's theorem. Lastly, the elliptic curve method of integer factorization is discussed. By making some improvement and through properly selected parameters, we successfully factored an integer of 55 digits, which is the product of two 28-digit primes.

According to the feeling of humans, it is not clear to show something, from time to time, we are not sure whether we should insist on our feelings, but we do like that ,cos we can't control ourselves, when you fall in love river, maybe you will lose your intellect , some words , some smile, some comportment could make you remember forever, we can't choose to remember something ,and forget something , once something happened in our lifes, it becomes past. What it left to us is the memory, I think memory has the life-span, and it was controlled by our minds. There is a rule to memory, if you force yourself to forget something ,usually , you must fail to forget something, cos a kind of consciousness in your mind make you remember that more and more clearly,, it is difficulty to fade something from one's memory by action,,, the only way to forget is the time , the time owns huge power to control human beings mind… waimaozu_com

关于人类的情感，这是个不太容易可以去诠释的东西，时而，我们并不确定我们是否应该坚持自己的情感，但是那样做了，因为我们无法控制自己内心的情感，当人们坠入爱河的时候，很多时候又会失去理智，一些言辞，一些微笑，一些举止都会让我们永久的铭记，我们无法选择性的去记忆什么，淡忘什么，一旦什么事情发生在我们生命里，即刻就成为过去，它留给我们的就只是"记忆"，然后记忆是有生命的，它被我们的思维所控制，对于这点有个规则是这样说的如果人们刻意的去淡忘什么，通常情况下，人们无法做到真正的忘却，因为人的大脑里有种潜意识会让我们越来越记忆深刻，所以通过某些方式让记忆消失并不是一件容易的事情，可以选择淡忘的唯一方式就是----时间，时间既有巨大的能量，它可以操控人们的思想。

It being in spring and the small birds they were singing Down by a shady arbour I carelessly did stray Where the thrushes they were warbling The violets they were charming For to view two lovers talking a while I did delay She said,"My dear, don't leave me all for another season Though fortune may be pleasing I'll go along with you I'll give up friends and relations and quit this Irish nation And to the bonnie Bann banks forever I'll bid adieu" He said, My dear, don't grieve me or yet annoy my patience You know I love you dearly although I'm going away I'm going to some foreign nation to purchase a plantation For to comfort us hereafter all in America. The landlords and their agents, their bailiffs and their beagles The land of our forefathers we're forced for to give o'er And we're sailing on the ocean for honor and promotion And we're parting with our sweethearts, it's them we do adore If you were in your bed lying and thinking of dying One sight of the bonny Bann banks, your sorrows you'd give o'er And if your were but one hour all in her shady bower Pleasure would surround you, You'd think on death no more So fare thee well, sweet Craigie Hill, where ofttimes I have roved in I never thought in my childhood days I'd part you any more But we're sailing on the ocean for honour and promotion And the bonny boat's sailing way down by Doorin shore

We may get creaky and cranky as we get older, but we can be happier than we were when we were young.

随着进入迟暮之年，我们也许会老态龙钟，脾气暴躁，但我们能够使自己比年轻时更快乐。

The main job and contribution of this paper are as follows:Based on narrowband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, compute the cross-correlation function of FH signals from multichannels, then we get the cross power spectral density matrixCSDM Secondly, select the hops of FH signals from the CSDM via processing and analyzing the CSDM, meanwhile reduce the influence coming from noise, fixed frequency signal and other interferences; Lastly, estimating the DOA of every hop and according to the DOA, we can separate the hops, get the number of FH signals and their parameters. Propose a new method for designing the threshold in FH signal detection. This method makes it easy to get the threshold by theoretic computing and it can extremely reduce the interference of non-FH signals.Based on broadband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, get the DOA of the signals by wideband spatial spectrum estimation; secondly, separate the signals by spatial filtering using wideband beamformer; Lastly, we propose two methods for FH signal blind detection and blind parameter estimation, one is for several constant hop-rate FH signals whose dwell-time are different and another is for a single FH signal whose hop-rate is alterable.By employing spatial interpolation in broadband signal beamforming, it can reduce the number of antenna elements and corresponding RF modules, A/D converters, etc. It can also eliminate the mutual coupling between antenna elements while getting the narrower main beamwidth and lower sidelobe level.

本文的主要研究工作和贡献如下：●提出了一种基于窄带处理的FH信号盲检测和参数盲估计的实现方法，即首先求出多路信号之间的互相关，进而得到互功率谱密度矩阵，然后通过对CSDM进行对折处理来抑制噪声、定频信号及其他干扰的影响，并将所有属于FH信号的hop(每一跳的驻留时间在时频图上持续的线段)从CSDM中筛选出来，最后用阵列信号处理中的到达方向估计理论在频域中估计出各个hop的方向参数，利用方位信息完成FH信号分离并得到FH信号的数目及其各自的参数集；●提出了一种确定FH信号检测门限的策略，该策略不仅使得检测门限能够通过理论计算得到，而且还显著地抑制了非跳频信号的干扰，从而能有效地检测出FH信号；●提出了一种基于宽带处理的短波FH信号盲检测和参数盲估计的实现方法，即首先利用宽带空间谱测向技术得到接收信号的DOA，然后采用宽带波束形成技术对特定方向进行空间滤波，实现多个信号的分离，最后分别提出了两种FH信号的盲检测和参数盲估计方法，第一种方法适用于空间某个特定方向上存在着几个驻留时间不同的恒跳速FH信号和其他干扰信号的混合信号，第二种方法适用于空间某个特定方向上仅含一个可变跳速的FH信号和噪声的混合信号；●将空间插值的概念和宽带波束形成技术结合起来，提出了一种基于频域处理的宽带恒定束宽的波束形成方法。

We are not covering silent films in this course. We will begin with the first talking motion picture, The Jazz Singer, released in 1927. The next week, we'll be looking at The Gold Diggers of 1933, a piece that is very representative of the escapist trend in films released during the depression. Some of the films we will be watching will probably be new to you, like Frank Capra's Why We Fight. Others you might have already seen on TV like Rebel without A Cause starring James Deane, or Stanley Cooper's Doctor's Strange Love. However, I hope you see even familiar film with new eye.

这门课不讲无声电影，我们将从1927年放映的第一部有声电影＇爵士歌手＇开始，下周我们也将观看1933年放映的＇掘金人＇，一部非常能表现萧条时期逃避注意的电影，有一些电影对你们来说可能很新奇，象F rank Capra 的＇为什么我们会打架＇，别的你们可能在电视上已经看过了，象 James Deane 主演的＇没有目标的反抗＇或 Stanley Cooper 的＇医生的怪癖＇，但是我希望你们对即使很熟悉的电影，也采取一种崭新的观点去看，在本课程的最后三周内，我们会观看一些80年代的影片，同时你们需要从中选出一部电影作为撰写深入评论的对象。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
