Sequential tests of educational progress 學業進度循序測驗
At last , based on amsaa model , the sequential testing approach is presented by bayesian method , while testing analysis and evaluation in small - sample circumstances is taken into account . and the optimal sample size is evaluated in given testing circumstances 最后,在amsaa模型的基礎上,結合小子樣試驗分析與評估技術,利用貝葉斯方法建立了可靠性增長的序貫試驗方法,并對給定條件下試驗的最優樣本量進行了評估。
The security of the algorithm is analyzed from the randomness , linear complexity of the chaotic sequence and the intensity of initial key . the results show the randomness of the key sequence pass the frequency test , sequential test , poker test , autocorrelation test , runs test , etc . and the total level is better than the binary sequence generated by the prng of delphi 7 . 0 , logistic chaotic system and rc4 , the linear complexity comes up to the expectation , the initial key has very strong intensity 本文最后從混沌序列的隨機性、線性復雜度和初始密鑰的強度三個方面對算法進行了安全性分析,結果表明算法產生的密鑰序列的隨機性完全通過了頻數檢驗、序列檢驗、撲克檢驗、自相關檢驗和游程檢驗等5種統計檢驗方法的檢驗,而且整體水平要好于delphi7 . 0中的偽隨機數發生器、 logistic混沌系統和rc4三種方法產生的二進制序列,線性復雜度達到了數學期望值。
Besides , how to improve sequential test is discussed . then , the data structure design of reliability block diagram and assessment algorithms of system reliability software is discussed , the method how to resolve the key problems is given , the functions of the software and how to use is introduced , too 同時,以二項分布為例,討論了序貫檢驗方法的改進然后,討論了武器系統可靠性評估軟件的可靠性框圖數據結構設計和評估算法實現,給出了關鍵問題的解決辦法,簡要介紹了軟件的功能與使用。
