First, CLBAC, a central load balance mechanism based on AC is proposed in this paper to increase security. Second, a distributed load balance mechanism is proposed. In DLB, each user can pre-estimate the actual load of each cell by means of virtual distributed coordination function, and then access the cell whose load is the lightest.

This method first jitters chirp rate polarity of LFM signal transmitted by the radar in slow-time domain,then does match-filters for the jamming signals hidden in the radar echoes,since jamming is more powerful than radar echo,the next process of limiting will lower the amplitude of jamming greatly,after limiting process,limited echoes are inversely match-filtered,so jamming and real radar echo are all back to the original time domain,then the next normal imaging process can be implemented which will also provide the real radar echo more gain than jamming,so SJR(Signal-to-Jamming Ratio) is further enhanced.

It introduces China pharmaceutical industry's characters and problems and then analyzes influence factors from the macroscopically, interspaced and microscopically views. Chapter four is the empirical research part in this paper. It introduces the principal of appraisal index and the choosing of the indexes. Then it introduces the building of model and its disposal method in Spss. To get a clear view of principal components analysis the paper analyzes the differentiate and connection between PCA and factor analysis. In this basement, the paper introduces the disposal process and results of the model. The paper then improves the model with entropy right method to eliminate the portrait diversity of data. To validate the model's stability, the paper makes a significance test of the four results.

第四章是本文的實證研究部分男女在一起怼怼怼的APP不用下，首先介紹了評價指標(biāo)選取的原則和指標(biāo)的確定综合激情图片；然后介紹了模型的構(gòu)建及其在spss中的處理原理，由于主成分分析法不能在spss中直接實現(xiàn)曰本色色色，且其原理和操作都易與因子分析相混淆在线网站搞点激情，所以本節(jié)首先分析了主成分分析法和因子分析法的區(qū)別和聯(lián)系，在此基礎(chǔ)上描述了怎樣在spss的因子分析的基礎(chǔ)上利用主成分分析法進行投資價值評價模型的數(shù)據(jù)處理人人操一级片；然后介紹了模型的數(shù)據(jù)處理過程和輸出結(jié)果免费一级a一级a久久无码，隨后利用熵權(quán)法對模型做了進一步改進，消除了數(shù)據(jù)間的縱向差異性欧美4444视频，并對改進前后的輸出結(jié)果進行顯著性檢驗性爱网址入口，以驗證模型的穩(wěn)定性。

The paper consists of five parts. Firstly I carry on a review to the domestic and foreign scholars" research on the stock price manipulation, in the second part, the paper takes an objective analysis of the way in which china"s stock market is manipulated and the cause of the manipulation. In the third chapter, firstly I find that auto-correlation of time series of stock return and persistency of the GARCH model could be an index for speculative price by comparing the characters between the speculative price and non-speculative price presented by GARCH modeling, and then stick out that low β coefficient is an important symbol of stock price manipulation through empirical study.

Presence of multiples leads to poor quality in main stages of offshore seismic data processing, such as velocity analysis, stacking and imaging. Three basic multiple attenuating methods are reviewed; and a more effective multiple attenuator is achieved by joining them. As the first step, shot or receiver records are extrapolated by wave-equation datum algorithms. The extrapolation will establish a model of waterbottom multiples. Waterbotton multiples will then be removed by subtracting the extrapolated records from the original records. After that, predictive deconvolution is used to attenuate the multiples created by source ghost. Finaly, RADON transformation is adopted to separate peg-leg multiples and residual water-bottom multiples from the original data in the τ-p domain.

地震勘探尤其是海上地震勘探中存在著各類多次波亚洲伊人色宗网一区二区，由于多次波的存在嚴重影響了速度分析久久一纵黄片、疊加、偏移成像等地震資料處理欧美午夜一级黄色，海上多次波主要有全程多次波和層間多次兩大類人人操免费网，為了壓制海上不同類型的多次波，本文首先分析波場外推黄色网址在线播放视频、預(yù)測反褶積和拉東變換衰減不同多次波的理論基礎(chǔ)毛片免费在线观看的，然后聯(lián)合采用這些方法，分別衰減全程多次波和層間多次波swag在线观看；即：首先對炮記錄或者接收點記錄進行波場外推一区二区黄片在线播放，建立海底多次波模型，預(yù)測并減去全程多次波鲁鲁网站内射污，然后利用預(yù)測反褶積衰減掉周期性明顯的多次波人人操人人干的黄片，最后將數(shù)據(jù)轉(zhuǎn)換到τ-p 域，用拉冬變換根據(jù)同一時間多次波和有效波在速度等方面的差異性生大片免费观看一级在线，進一步分離層間多次波和剩余的全程多次波18,禁止网站，并在該域中切除分離出的多次波，從而實現(xiàn)聯(lián)合多次波衰減處理亚洲国产欧美一区,二区。
