Abus lis overload protection . lifting is interrupted when 1 , 1 times rated load is reached . the electronic measurement method used features extremely short load detection times 安博lis過載保護裝置。該裝置當(dāng)載荷超過額定載荷的1 . 1倍時中止葫蘆起升。該裝置檢測時間短。
We construct weak classifier by a haar feature ; then weak classifiers are combined to a strong classifier in a linear way . the final classifier is built in a cascade structure , which could reject most non - face samples in the early layer . also we use integral image to quickly calculate the feature and reduce the detection time 本文以簡單的haar特征結(jié)合閾值構(gòu)造弱分類器,通過adaboost學(xué)習(xí)選擇和集成弱分類器,最后按照分層結(jié)構(gòu)把集成的分類器組合在一起;同時,在檢測過程中采用積分圖的方法計算特征,保證了檢測的速度。
1 . in the mpn - griess method of enumeration of nitrite - oxidizing bacteria , the nitrite concentration deeply effect the enumeration results and detection time . the o . lmmol / l nitrite concentration in the culture is the best choice for mpn - griess method and the shortest detection time is 4 week 硝酸細菌mpn ? griess計數(shù)法所用培養(yǎng)基的亞硝酸鹽濃度對計數(shù)的周期和結(jié)果均有影響,采用0 . 1mmol l亞硝酸鹽的培養(yǎng)基,進行4周的計數(shù)培養(yǎng),是最優(yōu)的硝酸細菌mpn ? griess計數(shù)法。
In order to withstand more and more frequent compound network attacks and hacker commitment of distribution , multiobjective , multistage nowadays , improve intrusion detection efficiency under the circumstance of high band width and large - scale network , decrease false negative rate and shorten detection time , incorporating advanced machine learning techniques into ids is already a well - known thought 為了對付目前越來越頻繁出現(xiàn)的分布式、多目標(biāo)、多階段的組合式網(wǎng)絡(luò)攻擊和黑客行為,提高在高帶寬、大規(guī)模網(wǎng)絡(luò)環(huán)境下入侵檢測的效率、降低漏報率和縮短檢測時間,把先進的機器學(xué)習(xí)方法引入到ids中來已成為一種共識。
