Under the horizontal earthquake action and wind force, aim at " the pure frame structure with rectangle columns ", " the pure frame structure with special - shaped columns ", " the frame - truss structure with special - shaped columns " and " frame - shear wall structure with special - shaped columns ", earthquake action analysis was done by the spacial finite element method through the changes structural parameter. analyzing systematically " structure vibration mode ", " vibration period ", " structure lateral rigidity ", " seismic action force ", " seismic response force ", " floor seismic shear force ", " lateral horizontal displacement of structure " and " members internal force ". results indicate : ( 1 ) based on equal area, the special - shaped columns replaced the rectangle columns, the structural lateral rigidity enlarges, the lateral displacement minishes obviously, the earthquake response increase slightly, the biggest increasing amount of frame columns axis - compress ratio is smaller than 0. 08. the whole aseismic performance of structure has improved ; ( 2 ) when the section ' s length and section ' s thickness ratio of special - shaped columns is smaller than 3. 6, the structure benefits to resist seismic action ; ( 3 ) the angle of horizontal seismic action with the whole coordinate is 0 degree, structure earthquake response is bigger, belonging to a control factor of structure aseismic design ; ( 4 ) the frame - truss structure with special - shaped columns and the " a " - brace has the biggest lateral rigidity ; ( 5 ) the frame - shear wall structure with special - shaped columns have bigger lateral rigidity and smaller displacement, members internal force enlarged just rightly, have much superiority of resisting seismic action ; ( 6 ) in the higher seismic fortification criterion region ( 8 degree of seismic fortification intensity ), aseismic disadvantageous building site ( iii type site ), adopting special - shaped columns structure system, should reduce possibly the building ' s self - weight in order to reduce the earthquake response ; ( 7 ) the response spectrum method of computing seismic response and the time - history analysis method have similar analysis result
西安理工大學碩士學位論文在水平地震作用下,並考慮風荷載組合,分別對「矩形柱純框架結構」 、 「異型柱純框架結構」 、 「異型柱框一析架結構」及「異型柱框-剪結構」等四種結構體系,通過改變結構參數,運用空間有限元方法,進行地震作用計算。系統地分析研究「結構振型」 、 「振動周期」 、 「結構側向剛度」 、 「結構地震反應力」 、 「樓層地震剪力」 、 「結構側向位移」 、 「層間位移角」 ,以及「構件內力」 。結果表明:在等面積原則下,異型柱代換矩形柱后,結構剛度增大,側向位移明顯減小,地震反應力略有增加,框架柱軸壓比最大增幅小於8 % ,結構整體抗震性能有所提高;當異型柱肢長肢厚比小於等於3 . 6時,結構有利於抗震;水平地震作用力與整體坐標夾角為0度時,結構地震作用效應較大,屬結構設計的控制因素之一;異型柱框一析架結構採用「人」字斜撐,側向剛度大於「八」字斜撐和「人一八」字混合斜撐;異型柱框一剪結構側向剛度大、位移小,構件內力增大適中,是一種抗震性能優越的結構體系:在抗震設防烈度較高地區( 8度)和抗震不利的建築場地( m類場地) ,採用異型柱結構體系時,應盡可能減輕結構自重,降低地震作用力;分別採用「振型分解反應譜」法和「時程分析」法進行地震作用計算,兩種方法所得結果基本一致。By studying the discrete fourier transform properties of the band - limited digital signal, the authors introduce alternating projection neural networks into the paper, expand apnn ' s application scope from real field to complex field, and present several important conclusions on apnn. analyzing and discussing network ' s tolerance to noise, convergence rate and the spectral leakage problem of the truncated signal expected to be extrapolated by using these conclusions, the paper presents an extrapolation algorithm for band - limited signals based on alternating projection neural networks. a lot of simulation experiments show that the algorithm is effective. in addition, the algorithm is also effective to spectrum extrapolation. owing to adopting network structure, the algorithm is prone to parallel computation and vlsi design, and consequently can satisfy real time military processing needs
本文通過對頻帶受限數字信號的離散傅立葉變換特性的研究,引進了交替投影神經網路,並將其應用范圍從實數域拓廣到復數域,且給出了在復數域仍然成立的若干結論.運用這些結論,在對網路噪聲抑制、網路收斂速度及待外推信號因截斷而造成頻譜嚴重外泄問題的分析與討論的基礎上,提出了一種基於交替投影神經網路的外推演算法.模擬實驗表明該方法是行之有效的.另外,該演算法對頻譜外推同樣適用;由於它採用全互連神經網路結構,易於并行計算和vlsi實現,從而可滿足軍事上實時處理的需要According to the characteristic of digital adaptive heterodyne filter and the conception of interference counteraction, the paper presents a new structure to enable the filter track the interference signal precisely and control the width and depth of notch. through simulation, it is demonstrated that the new structure can suppress one or more interference signals and the filtering operation has little influence on signal spectrum
論文利用數字自適應外差濾波器的特點,運用干擾抵消的概念,提出了一種新的結構,能使濾波器精確跟蹤干擾信號,並能控制陷波的寬度和深度,經模擬驗證,該結構的濾波器能較好的抑制一個和多個干擾,同時濾除干擾后對信號頻譜的損害較小。In order to overcome the disadvantages of the existed frequency spectrum analyzer instrument, the idea of software radio was applied, and a scheme of rf virtual frequency analyzer instrument based on digital intermediate frequency was presented, then its feasibility was analyzed

食物與生命是一個永續的循環,究竟我們有沒有認真細心思索如何可以吃得更健康?本系列介紹六種基本的食材,溶合烹飪專門技術以科學和社會歷史角度去發掘每種食物最具價值的食譜。備有中文字幕。If you have knowledge in simple image processing, you may reduce the noise further by taking many exposure on the same object, and stack them together in computer. after gaining some experience, you many want to take close - up photos of clusters and nebula. since the magnifying and light collecting power of the camera lens is not enough, you have to connect the camera to a telescope
在1868年,法國天文學家pierre janssen發現了在太陽的光譜中,有一條奇怪的光譜線,起初科學家以為這是一種地球上並不存在的物質所造成的,所以把這種新物質命名為氦英文為helium ,這個字來自希臘語的helio ,意思即為太陽。The components of a digital image watermarking system are discussed in detail. advantages and disadvantages of various typical algorithms are analysed. two novel image watermarking algorithms in cepstrum domain for different applications are presented, namely 1 - dimension cepstrum transformation image watermarking algorithm and 2 - dimension cepstrum domain spread spectrum image watermarking algorithm
