Combining with the performances of danshan bridge, discussing the methods on the construction controlling and calculation of cable - stayed bridge, this paper raises an efficient construction controlling system, and realizes collecting construction data of the real bridge and technical information. by analyzing on the difference of theoretical calculation and real construction state, the author determines to take self - adapting construction controlling method which uses kalman filter method to identify and adjust construction parameters. by getting rational construction state from forward iteration method, this paper, taking concrete creep effect in consideration, raises a rational scheme to pre - remain deformation and adjust cable force
結合丹山橋的結構特點，通過對斜拉橋施工控制及結構計算方法的探討，提出了有效的施工控制系統，實現了對實橋施工數據和技術信息的採集；通過分析理論計算與實際施工狀態的差異，確定了以卡爾曼濾波法作為施工參數識別與調整的自適應施工控制方法；通過正裝迭代法確定其合理施工狀態，並考慮混凝土的徐變效應，提出了合理的預留拱度和索力調整方案。In this dissertation, the research trends for the problem have been introduced ; the ‘ dim ’ and ‘ point ’ has been strictly defined in mathematics from machine vision and human vision ; the ideal clutter suppression system based on clutter predication and the realization and evaluation of evaluation index has been studied, in succession the clutter suppression technologies have been researched. firstly, the classic nonparametric algorithm has been analyzed in detail and systematically, for it ’ s weakness that it cannot remove the non - stationary clutter ideally, kalman filter algorithm for clutter suppression in 2d image signal has been built. secondly, fast adaptive kalman filter is presented based on fast wide - sense stationary areas partition algorithm : limited combination and division algorithm based on quarti - tree algorithm, new taxis filter route algorithm which can break through the limitation of the necessity of pixel neighborhood of 2d filter and laplace data model with two parameters which is perfectly suitable for the residual image of kalman clutter suppression
首先分析了經典的非參數法，對於四種具有代表性的核，從前述的三個性能評價方面做了分析和對比，指出了其速度快的優點和對非平穩圖像適應性差的弱點，針對非參數法的弱點，重點研究了對非平穩圖像適應良好的卡爾曼雜波抑制技術:建立了非平穩圖像的類自回歸模型，在此基礎上建立了二維卡爾曼濾波基礎的兩個方程:狀態方程和測量方程;建立了非平穩圖像準平穩區域快速劃分演算法:基於四叉樹法的有限分裂合併演算法;二維空間的基於k排序的濾波路線演算法，突破了空域濾波路線上區域相鄰的限制;在這些研究的基礎上實現了快速卡爾曼估計，實驗驗證了該方法相對逐點卡爾曼估計可以提高運算速度三倍左右;雜波抑制結果表明傳統的高斯性檢驗並不適合卡爾曼估計后的殘余圖像，由此建立了殘余圖像的雙參數拉普拉斯模型，實驗表明其可以完好的吻合殘余圖像的概率密度曲線。Other than drug addicts, official statistics indicate the hiv virus that causes aids is spreading quickly to women, fishermen, lorry drivers and factory workers, said ramlee rahmat, deputy director - general of public health
據美聯社2月11日報道，馬來西亞政府公共健康部門代理負責人拉姆雷?拉赫邁特指出，除了那些濫用毒品者外，官方的統計數字表明， hiv在女性、漁民、卡車司機以及工廠工人這幾個群體中的傳播速度也正變得越來越快。
