劉家峽水庫網箱養魚場春季纖毛蟲群落結構Then, we analyzed solutions of the major techniques of the distributed web crawler, such as how the nodes of the crawler cooperate with each other, how the task is distributed, how to keep the important web fresh. we have proposed some practicable arithmetic to solve the problems mentioned above. besides, we implemented a robust, distensible, customized, distributed web crawler, and anatomized it
然後本文分析了分散式網路爬蟲的關節技術的解決方法,比如分散式的各個結點如何協同工作,任務如何分配,如何保持重要網頁的時新性等等,進而提出了一些實用的演算法,解決了這些分散式網路爬蟲的關鍵技術,實現了一個具備健壯性,可擴展性,可配置性的分散式網路爬蟲系統,並就該分散式網路爬蟲系統進行了仔細的剖析。The trail is about 1 km in length. it starts from the car park where a rain shelter with a green roof is located
小徑的首段是斜坡,兩旁為樹木,在那裡可細心靜聽不同雀鳥和昆蟲的鳴聲,或觀察巨型森林黃蜘蛛結網捕蟲的方法。Internet worms are difficult to eliminate because internet is an open and complex scale - free system, and there are a mass of vulnerable nodes, which are absent of managing and defending. if these nodes are infected with worms, worms will be left on them and may attack the other nodes on internet
網路蠕蟲之所以難于控制主要是由於internet本質上是一個開放的復雜巨系統,其結構復雜,缺乏中心控制能力以及其開放性的特徵導致存在大量網管層面上的不可控節點。By combining spreading models, population data extracted from real internet worm epidemics, and measured models of internet topology, we have shown that any reactive worm defense will require extremely widespread deployment and very short reaction times ( a few minutes or less )
通過結合傳播模式、數量等從實際的網際網路蠕蟲的傳播得來的數據,以及對網際網路拓撲結構的測量,發現任何反應式的蠕蟲防禦需要廣泛的部署和非常短的反應時間(即分鐘或更少) 。We designed and made the attraction device to attract agricultural pests, obtained agricultural pests " images with the color camera, processed images based on wavelet analysis. on the basis of these, we emphasized on extracting effective features, put forward recognizing pests " classes with pests " colors and texture features, and succeeded in extracting five efficient features such as color features, wave image edge moments features and so on. then we selected features, inputted into neural network classifier, recognized pattern, presented detection results
本文設計製作了誘捕裝置,誘集農田害蟲,使用攝像頭攝取害蟲圖像,採用小波分析進行圖像處理,在此基礎上重點進行了特徵提取工作,提出了利用害蟲顏色和紋理等特徵進行種類識別的觀點,並成功提取了彩色特徵、小波圖像邊緣矩特徵等五類有效特徵,並經特徵選擇后輸入神經網路分類器進行模式識別,最後給出檢測結果。As the program crawled the various web sites, it would build a database of the sites and pages crawled, the links each page contained, the results of analysis on each pages, and so on
當爬蟲程序爬過不同的web站點時,它將建立一個數據庫,該數據庫中包括它所爬過的站點和網頁、每一頁所包含的鏈接、每一頁的分析結果等數據。Later on, after elaborating the disadvantages of the old methods in detecting and recognizing moving objects, a series of corresponding approaches are proposed, such as grid scan, local tracking bug and dynamic window in object tracing to reduce the huge data needed to be processed, maximum and minimum for selecting a proper segmentation threshold and improved conversion from rgb model to hsv and so on to decrease the influence of inhomogeneous lighting and the color noise, a bilinear interpolation in each quadrant to eliminate the bad effect on the recognition precise because of the distortions of the camera. after that, much emphasis is given on application study in pattern recognition with a feed - forward neural network. both the basic bp algorithm and improved bp algorithm in the study process are described in detail, and the later is used to quicken convergence speed and improve validity of the network
然後,分析和闡明了傳統的運動目標檢測方法的不足,並在此基礎上結合研究中的實際實驗環境,提出了一系列解決方法,包括針對降低龐大數據量而提出的網格掃描、局部「跟蟲」追蹤和動態窗口掃描等目標檢測方法,針對實驗環境中光照不均和顏色干擾提出基於人機交互的最大最小值閾值選取方法和引入改進的rgb模型到hsv模型的轉換方法,為消除圖像畸變對識別精度的惡劣影響而採用的通過控制點進行雙線性插值進行畸變校正的方法;緊接著,概述了神經網路的發展歷史和幾種常用神經網路模型的特點,重點研究了前饋型神經網路在模式識別中的應用問題,詳細闡述了基本的bp演算法和學習過程中bp演算法的改進,從而使網路收斂速度更快,解決問題更有效,並在此基礎上,設計了一個基於bp神經網路的運動目標識別系統,給出了實驗結果。Meanwhile, the paper also argues the functions and principles of search engines of different types, based on which it analyzes advantages and disadvantages for search engines of different types. 2. the paper abstracts search engine into three parts by analyzing and discussing the news search engine ’ s structure and data flow
在本文中,中文資訊搜索產品的爬蟲的主要技術原理是利用[定製模板的方法] ,將爬蟲的[抓取策略]和[網頁內容的抽取策略]相結合,對web新聞的詳細信息進行採集和處理。分享友人
