As the inevitable choice of enterprises to adapt to the knowledge - based economy development, knowledge management is a process of creating value for enterprises confronting the increasingly complicate changes of environment by taking advantage of collective intelligence to reinforce the ability of learning, contingency and innovation, which requires enterprises to apply various means, including organizing, culture, process, technique, strategy, and to establish the knowledge - respecting and talents - respecting culture environment gradually which will promote knowledge accumulation, share, diversion, and improve the inner and outer application of knowledge network
知識管理作為企業適應知識經濟發展要求的必然選擇,其實質是企業在面對日益復雜的環境變化,綜合運用組織,文化、流程、技術、戰略等手段,通過有計劃,有目的的構建有利於知識的積累、共享、轉換和運用的內外知識網路以及尊重知識,尊重人才的文化氛圍,運用集體智慧提高企業的學習能力、應變能力和創新能力,並達到為企業創造價值的一種管理過程。We must therefore take full advantage of this year s limited breathing space to control expenditures in preparation of tougher times ahead. if the economic revival forecasted by the government is delayed, the pressure to control expenditures will be even greater. it is simply vital to have further contingency plans
換言之,財政司必需要掌握今年有限度的喘息空間,控制未來兩年的開支,若然政府預測的經濟復甦在時間上再稍有延誤,控制支出的壓力將會更沉重,政府必定要有進一步應變的準備。A port tyre crane has various parts and complex structure, which is made up plenty of beam - bar and shell elements, manual calculation can not guarantee the precision while finite element method needs onerous structure modeling and a great deal of date input. the finite element analysis and modeling of the port tyre crane are difficult because of complex structure and various loads. in order to fit further more design and exploitation of the same type as well as the upgrade of the production i study a kind of parametric software for structure analysis of the port tyre crane, it can reduce the difficulty of modeling and structure analysis as well as improve efficiency
港口輪胎式起重機部件繁多、結構復雜,由數目眾多的梁桿與板殼組成,其結構設計和力學分析使用傳統的手工計算方法難以保證精度,有限元方法則需要繁重的結構建模和大量的數據輸入,並且要求分析人員具有相當的力學知識和有限元基本理論。港口輪胎起重機結構的復雜性、載荷工況的多變性導致港口輪胎起重機結構有限元建模和分析工作效率低、難度大。針對這種情況本課題研發了一套港口輪胎式起重機結構的有限元參數化分析軟體,以適應同類機型的進一步設計開發和產品升級換代,降低建模和分析的工作難度,提高工作效率。In this paper, the backward simulation was summarizd at home andabroad, the characteristics of shell nosing were introduced, the theory and scheme of backward simul - ation of shell nosing was constructed, the determined methods of the boundary conditions were put forward in backward simulation for the processes of shell nosing
論述了推力矢量控制技術是提高空空導彈性能的核心技術,介紹了常用的三類推力矢量裝置,著重討論了燃氣舵式和擾流片式推矢裝置的特點、設計方法、性能及其優缺點.在此基礎上,研究了適用於氣動力/推力矢量復合控制的變結構控制系統及其開關函數的切換條件和飛行控制系統框圖.最後綜述了推力矢量裝置在第四代空空導彈上的應用情況But, though considerable process has been made in the last ten years, digital watermarking is still in its infancy, and much interesting work remains to be done this thesis addresses some problems in the gray - scale image digital watermarking that are summarized below : 1 ) whereas the basic theory of digital watermarking is still very poor, a digital watermarking mathematic model based on imperceptibility and robustness is presented by analysising the characteristic of digital watermarking ; 2 ) based on the model constructed above, by defining the measures of capacity and robustness of digital watermarking, an objective method for evaluating the digital watermarking is introduced and used to analysis some algorithms ; 3 ) whereas geometric distortion always influences the restoration of watermark, we advocate to enhance the robustness against geometric distortion by restoring the image which has been distorted by geometric transformation, and a method is designed for estimating the parameters of geometric transformation ; 4 ) based on the conclusion discussed above, and combined with the masking effects of hvs, a novel public meaningful gray - scale image digital watermarking is designed by analysising the characteristics of image gray - scale interpolation and haar wavelet transformation. the experimental results show that the method is indeed powerful ; 5 ) whereas many image digital watermarking schemes, which embed watermark by modifying the values of pixels in spatial domain and transformed domain, are confronted with the conflict between the imperceptibility and robustness, we advocated to use some stable digital characteristics of host image as watermark and a algorithm based on hermite matrix is designed
本文重點對灰度圖象數字水印技術進行研究,主要工作如下: 1 )鑒于目前數字水印的理論研究比較薄弱的現狀,本文通過分析數字水印的特點,建立了一個數字水印的數學模型,為進一步研究數字水印打下了基礎; 2 )根據以上建立的模型,通過引入容量和穩健度的概念為數字水印提供了一個客觀評價方法,並對一些數字水印演算法進行了分析; 3 )為增強數字水印抵抗幾何攻擊的能力,研究了受幾何攻擊的圖象的復原問題,並給出了一個計算圖象幾何變換參數的方法; 4 )通過分析圖象灰度插值演算法和haar小波變換的特點,結合hvs的掩蔽效應,設計了一個公開的有意義數字水印演算法,實驗結果表明本演算法具有較強的穩健性; 5 )目前許多水印演算法都是通過在空域或頻域修改象素值的方法嵌入水印的,這種方法面臨著透明性和穩健性的矛盾,為解決這個矛盾,本文提出以圖象的某些穩定的數字特徵為水印的觀點,並結合hermite矩陣的特點設計了相應的水印演算法,實驗結果表明該演算法具有較好的穩健性。This paper is devoted to seeking formulas and rules of representation for generating new fractal graphics. the main works are as followed : ( l ) construct new formulas for new fractal aspects after revisited methods for the visualisation of mandelbrot and julia sets based on ifs, we described the other new formulas originating from z z2 + c. including norton and polynomials iterated function, which have integer index instead quadratic index, we also constructed formulas with complex number index. 3 - d dynamical system is discussed then. besides the most widely used sequential visualisation methods, we designed two methods to change the original vectors and get new graphics with special effects
