簡介：無線傳感器網(wǎng)絡(luò)WIRELESSSENSWKWSN作為一種由大量節(jié)點組成的新型傳感網(wǎng)絡(luò)，具有應(yīng)用廣泛、快速部署的優(yōu)良特性。隨著信息行業(yè)和信息處理技術(shù)的迅猛發(fā)展，無線傳感器網(wǎng)絡(luò)的應(yīng)用開始逐漸普及，其中在環(huán)境檢測、能源勘探、農(nóng)業(yè)生產(chǎn)和生物研究等方面有著良好的應(yīng)用前景。拓撲控制是無線傳感器網(wǎng)絡(luò)研究的核心問題之一，合理的網(wǎng)絡(luò)拓撲結(jié)構(gòu)能夠延長網(wǎng)絡(luò)生存周期，減少節(jié)點間相互干擾并提高路由協(xié)議效率。無線傳感器網(wǎng)絡(luò)規(guī)模較大，傳感節(jié)點眾多，并且節(jié)點能量有限，因此，為了確保信息傳輸?shù)目煽啃?，無線傳感器網(wǎng)絡(luò)必須具有較強的容錯性。本文從網(wǎng)絡(luò)節(jié)能的角度出發(fā)，對無線傳感器網(wǎng)絡(luò)進行容錯拓撲控制研究，針對LEACH算法的缺點進行了改進，并設(shè)計仿真實驗進行驗證。主要研究工作及取得的創(chuàng)新性成果如下首先，分別從網(wǎng)絡(luò)節(jié)點和網(wǎng)絡(luò)結(jié)構(gòu)兩個方面對網(wǎng)絡(luò)的能耗進行了分析；對路由節(jié)能進行了研究，分析各路由協(xié)議的特點；選取典型的路由協(xié)議LEACH協(xié)議為研究對象，分析LEACH算法的計算流程，并設(shè)計仿真實驗，對LEACH協(xié)議的性能進行分析。然后，針對LEACH算法能量分布不均的缺點，提出了基于一種基于自適應(yīng)讓位策略的改進算法，通過設(shè)定一個能量門限來限定簇頭的選擇，和LEACH算法相比該算法能夠獲得更長的網(wǎng)絡(luò)壽命，并且提高了網(wǎng)絡(luò)的吞吐量。最后，從功率控制的角度出發(fā)，提出了一種基于遺傳算法的LEACH改進方案，該算利用節(jié)點位置信息及節(jié)點剩余能量對網(wǎng)絡(luò)進行分簇，綜合考慮簇內(nèi)節(jié)點剩余能量、簇內(nèi)覆蓋率和重復(fù)覆蓋面積等因素對簇內(nèi)節(jié)點進行睡眠調(diào)度，使拓撲結(jié)構(gòu)得到進一步優(yōu)化。通過仿真實驗對兩種改進算法從網(wǎng)絡(luò)壽命、節(jié)點剩余能量和吞吐量三個方面進行了對比分析。

簡介：摘要隨著中國經(jīng)濟的不斷發(fā)展，中國金融市場在社會經(jīng)濟領(lǐng)域中所起到的資源配置作用越加凸顯，在全球化市場的不斷完善、金融創(chuàng)新層出不窮的大背景下，金融市場的穩(wěn)定運作，己成為支持我國經(jīng)濟持續(xù)向前穩(wěn)步發(fā)展的重要因素，與我國未來的發(fā)展前景具有密不可分的聯(lián)系。在我國股票市場發(fā)展的二十多年歷史中，行業(yè)間的輪動現(xiàn)象始終是投資者關(guān)注的熱點。如果能夠把握市場中行業(yè)間不斷此消彼長的節(jié)奏，從行業(yè)配對交易策略入手，準(zhǔn)確預(yù)測相對表現(xiàn)強勢的行業(yè)，不僅能在一定程度上揭示股票市場的運行規(guī)律，更能在實踐中對投資起到良好的指導(dǎo)作用。神經(jīng)網(wǎng)絡(luò)技術(shù)，因其具有的非線性映射、對于樣本的自適應(yīng)能力等優(yōu)點，一經(jīng)面世就受到了學(xué)術(shù)界很大程度的關(guān)注，隨著其在模式識別、智能控制等工程領(lǐng)域所取得的一系列成功，人們逐漸發(fā)現(xiàn)，神經(jīng)網(wǎng)絡(luò)擅于揭示數(shù)據(jù)間復(fù)雜的非線性映射關(guān)系的特性，為揭開金融市場中變量間的相互關(guān)系提供了有效的途徑。本文首先通過市場中，不同行業(yè)的市盈率序列的平穩(wěn)性與協(xié)整性出發(fā)，指出市盈率序列的差值往往具有更強的“均值回復(fù)特性”，從而表現(xiàn)出不同行業(yè)間的相對估值通常比行業(yè)本身的絕對估值具有更強穩(wěn)定性。進而通過引入BP神經(jīng)網(wǎng)絡(luò)技術(shù)，結(jié)合本文的預(yù)測對象，對BP網(wǎng)絡(luò)的輸入變量，網(wǎng)絡(luò)結(jié)構(gòu)，初始權(quán)值、訓(xùn)練方法等多個方面進行了優(yōu)化。最后以金融服務(wù)行業(yè)與醫(yī)藥生物行業(yè)為例，采用滾動預(yù)測法，對2011142012229間的行業(yè)間相對強弱關(guān)系進行了預(yù)測。仿真的結(jié)果表明，基于BP網(wǎng)絡(luò)對于行業(yè)間相對強弱關(guān)系的預(yù)測是切實可行的，并且對實際投資也具有很強的指導(dǎo)意義。關(guān)鍵詞量化投資，行業(yè)配對，BP神經(jīng)網(wǎng)絡(luò)，協(xié)整性檢驗1目錄艘1ABSTRACT21緒論411選題背景412數(shù)理金融與量化投資在國內(nèi)外發(fā)展歷史與現(xiàn)狀513本文的研宄目的1014本文框架112市盈率序列協(xié)整性與行業(yè)配對交易策略1221行業(yè)輪動現(xiàn)象與行業(yè)配對交易策略1222市盈率序列的平穩(wěn)性與協(xié)整性檢驗1323本章小結(jié)183神經(jīng)網(wǎng)絡(luò)模型的構(gòu)建1931神經(jīng)網(wǎng)絡(luò)模型的發(fā)展歷史與特性1932BP神經(jīng)網(wǎng)絡(luò)2133本章小結(jié)294基于神經(jīng)元網(wǎng)絡(luò)的行業(yè)輪動投資策略仿真3041投資策略仿真系統(tǒng)的設(shè)計邏輯3042樣本數(shù)據(jù)的選擇3143BP神經(jīng)網(wǎng)絡(luò)的構(gòu)建3744仿真結(jié)果與分析4145本章小結(jié)485辦4951本文的主要研宄成果4952本文的創(chuàng)新之處4953下一步工作方向50參考書目52附錄行業(yè)間相關(guān)系數(shù)矩陣54觀573
