李維諾夫
英文
maxim litvinov-
We describe the meaning of chaos > future idea of chaotic theory and influence on forecast ; introduce the character of chaotic time series, and point out the problem and shortage of the methods already existed computing character value which are fractal dimension and the largest lyapunov exponent and improve on it ; present the forecast principle of forecast method based on chaotic attractor, and point out the shortage of local field forecast method based on chaotic attractor and bring forward improved on methodo at the same time, we put forward a banausic algorithm and compare two models using practical example
論述了混飩的含義與混淪理論的未來觀及其對預測的影響；介紹了。混飩時間序列的特徵，指出了己有的計算分形維及最大李雅譜諾夫指數這兩個特徵量的方法存在的問題與不足，並對此進行了改進；給出了基於混飩吸引子的預測方法的預測原理，指出了常用的基於混燉吸引子預測的局域法的不足並給出了改進方法，同時，給出了其實用演算法，並用實例進行了比較。Then r / s analysis, phase space reconstruction of the system, chaos analysis and fractals analysis are done through matlab program, based on original data of hushen stock markets compositive index from year 1991 to year 2002. and the author draws a conclusion based on original data that china ' s stock market obeys low - dimension fractals and ebb - chaos in terms of the experimentation result : hurst exponents are between 0 and 1, memory cycles are obvious, lyapunov exponents are more than zero and chaotic attractors correlative dimensions are between 2 and 3 in hushen stock markets in this thesis the concept information noises is put forward. stock market information about policy and company of the last ten years is packed up and classified for regulators make decisions in terms of power the factor influences the stock market index
之後文章以中國股市1991年至2002年上海和深圳綜合指數每日收盤價原始數據為研究對象，在matlab程序實驗條件下，進行了兩地股市系統的r / s分析、系統相空間重構、混沌分析、分形分析；獲取了兩地股市系統的赫斯特指數（滬深股市赫斯特指數均大於0 . 5而小於1 ） 、非周期記憶循環周期（滬深股市都有明顯的記憶循環周期） 、最大李雅普諾夫指數（兩市都大於0 ）和吸引子的關聯維數（兩市都在2到3維之間） ；從而得出中國股市系統是低維分形的、弱混沌的（基於原始數據）結論。At first, construct ten sets of surrogate data for each emg data, then calculate the correlation dimension ( dcorr ), correlation time, maximum lyapunov exponent ( a, ), l - z complexity and approximate entropy ( apen ) of both the original emg data and surrogate data, and then compare them
構造這四例肌電信號的代替數據（各十組） ，分別計算原數據及其代替數據的關聯維、關聯時間、最大李雅普諾夫指數、 l - z復雜度和近似熵，我們發現，四例原數據的以上所有特徵量都與各自所對應的十組代替數據存在明顯差別。Criteria for the nonlinear dynamic stability of rotative vehicles are derived by the liapunov ' s first method and the routh - hurwitz stability criterion, this criteria can be applied to the dynamic stability analysis of controlled rotative missiles, projectiles and rockets
應用李亞普諾夫第一近似理論和勞斯霍爾維茨方法導出了旋轉飛行器的非線性運動穩定性判據，這個判據可應用於有控旋轉導彈的運動穩定性分析，也可應用到炮彈和火箭彈上。These include two keys problem in phase space reconstruction theory, that is embedding dimension and optimal delay time, and numeric recognition of chaos, that is lyapunov exponent, as well as numeric recognition of fractal, that is correlative dimension of chaotic attractors
其中重點講述了非線性動力學的數值研究實驗方法：相空間重構的兩個關鍵問題，即嵌入維數和最佳延遲時間；混沌的數值識別，即李雅普諾夫指數；分形的數值識別，即吸引子的關聯維數。分享友人
