Parallel computing means to handle several missions, several instructions or data units so as to improve processing speed 并行處理是指同時(shí)對(duì)多個(gè)任務(wù)或多條指令、或多個(gè)數(shù)據(jù)項(xiàng)進(jìn)行處理,從而大大提高計(jì)算速度。
5 . a speckle filter based on emd is proposed, it smooth along edge direction in edge area and compute mean of square area in homogenous region, therefore this method can reduce speckle while preserve edge in sar images 提出了基于emd方法的sar圖像斑點(diǎn)濾波方法;這個(gè)方法在邊緣區(qū)域沿著邊緣方向平滑,在同質(zhì)區(qū)域在方形窗口內(nèi)取平均,因此這個(gè)方法在去除斑點(diǎn)同時(shí)能夠有效保持邊緣。
The formulas for computing mean and deviation of the average consolidation degree of double-layered soil are derived as vertical coefficient of consolidation submitting to gamma distribution . with these formulas, the influence of geotechnical auto-correlation distance to the probability characteristics of consolidation degree is studied . it shows that along with the rising of auto-correlation distance, the sensitivity of probability characteristics of consolidation degree to auto-correlation distance is falling 當(dāng)豎向固結(jié)系數(shù)為gamma分布時(shí),推導(dǎo)了雙層地基平均固結(jié)度均值和方差的計(jì)算公式:利用該公式分析了土性自相關(guān)距離對(duì)平均固結(jié)度概率特性的影響,結(jié)果顯示,自相關(guān)距離越大,平均固結(jié)度的概率特性值對(duì)自相關(guān)距離越不敏感。
Provide automatic test function of fiber diameter, directly observe fiber configuration on screen, and display the actual diameter of all fiber on-time . fast test speed, simple operation, and reduced personal error . automatically compute mean diameter, coefficient of variation and standard deviation of the tested fiber, the tested date can be printed out by excel 提供了纖維直徑自動(dòng)測(cè)量功能,可直接在顯示器上觀察纖維形態(tài),實(shí)時(shí)顯示每根纖維的實(shí)測(cè)直徑;測(cè)量速度快,操作簡(jiǎn)便,減少了人為誤差;可自動(dòng)計(jì)算已測(cè)纖維的直徑平均值、變異系統(tǒng)和標(biāo)準(zhǔn)差,測(cè)試數(shù)據(jù)可以excel報(bào)表形式打印輸出。
The development of mechanized mathematics goes through tortuous way in the western countries, written calculation is the most compute means . the mechanized degree of writing calculation is lower, and not meet the actual demands . other means, example : table calculation, slide rule, graphic solution, are invented to make up the defect of writing calculation 由于西方比較崇尚公理化數(shù)學(xué),不易想到要從筆算在機(jī)械化方面存在的缺陷上尋求改進(jìn)方向,以選擇和設(shè)計(jì)算具算法;而是另外尋找別的計(jì)算方式、工具,如表算、計(jì)算尺和諾模圖等來(lái)解決應(yīng)用計(jì)算問(wèn)題,走了彎路。
To increase the features of rrssms, we improved the reliability of application-level to build a more reliable asynchronous communication model over the existing corba event service, and presente d a technique of web-based active information publication supported by distributed object computing means embedded in web architecture . in this method application server can push information to the web client with the active information publication scheme 同時(shí),為了提高web應(yīng)用系統(tǒng)的實(shí)時(shí)性,以更適合遠(yuǎn)程監(jiān)控系統(tǒng)的需要,在應(yīng)用層對(duì)corba事件服務(wù)標(biāo)準(zhǔn)的可靠性作了改進(jìn),構(gòu)建了中,一個(gè)可靠的異步通信模型,并結(jié)合對(duì)象web技術(shù)提供的分布式對(duì)象計(jì)算平臺(tái),實(shí)現(xiàn)了一個(gè)web主動(dòng)信息發(fā)布機(jī)制,利用該機(jī)制,應(yīng)用服務(wù)器可以主動(dòng)把信息推送到web的客戶端,提高了web系統(tǒng)的實(shí)時(shí)性。
