By statistical computation we prove that the confluence process of jiangjia ravine obeys the power-law frequency-area distribution 本文通過統(tǒng)計(jì)計(jì)算得到,蔣家溝泥石流匯流和流量過程在暴發(fā)頻率與泥石流總徑流量上服從負(fù)冪律分布。
This paper presents a new sampling method, which is called sampling method by allocating random order to percentiles based on some random simulation problems of statistical computation 摘要該文針對統(tǒng)計(jì)計(jì)算中的某些隨機(jī)模擬問題提出了分位點(diǎn)隨機(jī)配序抽樣法。
Image difference operation is applied to video images taken with image capture device, then statistical computation is performed to judge whether there is vehicle violating the regulations, and corresponding measures are taken 由攝像頭獲取的視頻圖像經(jīng)計(jì)算機(jī)進(jìn)行圖像差分運(yùn)算,結(jié)合統(tǒng)計(jì)算法由計(jì)算機(jī)根據(jù)所得數(shù)據(jù)判斷監(jiān)測區(qū)域是否有違章車輛出現(xiàn)并作出相應(yīng)的處理。
Latent semantic analysis ( lsa ) is a completely automatic theory and method of the acquisition and representation of knowledge, which extracts the contextual-usage meaning of words by statistical computations applied to a large corpus of text 潛在語義分析(latentsemanticanalysis,lsa)是一種用于自動(dòng)地實(shí)現(xiàn)知識提取和表示的理論和方法,它通過對大量的文本集進(jìn)行統(tǒng)計(jì)分析,從中提取出詞語的上下文使用含義。
The statistical software platform with a certain extent of intelligence abstract statistical software, which is used as a powerful tool in the field of statistical computation, can play very important role . good statistical software should have the features described as follow : 1 一個(gè)好的統(tǒng)計(jì)軟件應(yīng)該具備以下基本特征:1、擴(kuò)充性好:要求能夠適應(yīng)數(shù)理統(tǒng)計(jì)科學(xué)的不斷發(fā)展,具有較強(qiáng)的適應(yīng)能力,增加新的統(tǒng)計(jì)數(shù)據(jù)類型、新的統(tǒng)計(jì)模型簡便、快捷。
In this article, the concept of statistical template based on data was firstly brought forward, which can effectively simulate the entire statistical computation process by recording the information of data structure and analytic method . we make the statistical template as theoretical basis of statistical analysis platform ( sap ) the statistical template can make our sap has the properties described as follow : 1 . good facility the requirement is to have the statistical knowledge, user need n't has any background of computer science and computational mathematics; the time that is used to learn is short 本文通過對一般統(tǒng)計(jì)計(jì)算過程的分析,提出了以統(tǒng)計(jì)數(shù)據(jù)為中心的統(tǒng)計(jì)分析模板的概念,該概念以統(tǒng)計(jì)字段來描述統(tǒng)計(jì)數(shù)據(jù)的數(shù)據(jù)結(jié)構(gòu),通過記錄統(tǒng)計(jì)數(shù)據(jù)結(jié)構(gòu)信息及其相應(yīng)的統(tǒng)計(jì)分析計(jì)算服務(wù)信息的形式在邏輯上有效地模擬了統(tǒng)計(jì)計(jì)算的全過程,從而為統(tǒng)計(jì)軟件平臺構(gòu)建了一個(gè)堅(jiān)實(shí)的理論基礎(chǔ),使該統(tǒng)計(jì)軟件平臺具備了以下特點(diǎn):1、易于使用概念清晰、使用簡便,作分析工作時(shí)使用者無需任何計(jì)算機(jī)科學(xué)和計(jì)算數(shù)學(xué)背景知識,懂得基本操作即可,學(xué)習(xí)周期短。
And we use statistical computation and relativity analysis for the first time . so we make the conclusion that the simulation system obeys the power-law frequency-area distribution by improved 2-d ca model . and by relativity analysis we know simulation sequences are long correlative 通過改進(jìn)的二維沙堆自動(dòng)機(jī)模型的構(gòu)建和模擬,本文得到了一系列模擬數(shù)據(jù),并在此基礎(chǔ)之上,首次通過統(tǒng)計(jì)計(jì)算和相關(guān)性分析,得到如下結(jié)論:(1)改進(jìn)的二維沙堆自動(dòng)機(jī)所模擬的系統(tǒng)在沙粒暴發(fā)頻率對暴發(fā)規(guī)模的關(guān)系上服從負(fù)冪律分布。
