  1. Further, combat channel errors algorithm of collaborating mdc and ecn is presented for video

    進一步地，提出md - 3d - spiht與差錯隱藏的聯合抗誤碼演算法。
  2. The main work is as follows : 1. an error resilient algorithm to collaborate multiple description coding ( mdc ) and error concealment ( ecn ) is presented. the strategy of this method is to reconstruct the low quality image followed by recovering the lost wavelet tree with error concealment method when end - user receives few descriptions

    在誤碼環境下，要保證解碼端重構圖象的質量，就要綜合採用多種抗誤碼方法，本文對差錯復原技術的綜合應用進行了研究，具體內容如下: 1 、提出了圖象多描述編碼與差錯隱藏相結合的差錯復原演算法，在接收端接收到的描述較少時，首先根據接收到的若干描述重構低質量的圖象，然後採用差錯隱藏方法恢復丟失的子波樹。
  3. ( 2 ) with the increasing applications of real - time multimedia on internet, an ecn - based tcp - friendly congestion control ( etcc ) scheme was proposed. the scheme emphasizes on the improvement of end host with the support of extended router. red was adopted in the router, and early congestion state was notified to the sender using ecn

    （ 2 ）針對internet上與日俱增的實時多媒體應用，提出了一種基於ecn的tcp友好擁塞控制機制etcc ，該機制側重於端系統功能的改進，同時擴展了路由器的功能來支持端系統的工作，在路由器中採用red管理隊列長度，以ecn的方式將網路的早期擁塞狀況通知端主機，端系統根據相應的速率調節機制來調節數據的發送速率。
  4. The monitoring carried out at each ecn site covers a range of physical, chemical and biological measurements

    在每一個環境變化網路地區進行的監控都包括一定范圍的物理、化學及生物測量。
  5. It is found ecn could n ' t solve the problem that the sender responds to congestion slowly, and the average queue length of router is sensitive to the static parameters of ecn. in chapter four we propose an algorithm called fecn, which provides congestion control and indication messages in router, so that the sender could response to congestion in good time. this algorithm can also adjust the max drop probability according to the active conne

    Ik的特性，而且平均隊列長度和網路吞吐量對ecn的靜態參數較為敏感，因此本文在第4章中提出了一種fecn演算法，該演算法在路山器處提供擁塞控制和指示機制，使源端能夠快速響應路由器發回的擁塞指示消息，調整發送速率，避兔擁塞的發生，該演算法還可以通過估計鏈路中的活動連接數動態調整最大丟棄概率。
  6. The essence of aqm is to detect the incipient congestion before queue overflow. when congestion has been detected, packets would be dropped or be marked ( ecn ) with a probability to send congestion notification to the sources

    Aqm的本質就是在隊列溢出之前檢測出早期的擁塞，並且以一定的概率丟棄或者標記（ ecn ）數據包，從而向源端發出擁塞指示，以緩解網路擁塞。
  7. To avoid busy traffic, hctcp also paces packets in the first rtt by using token technology. the simulation tests show that hctcp could reduce the transmission time either in local or satellite networks especially for short connections such as web traffic. as one of the active queue management algorithms, ecn changes the way of congestion indications

    作為一種主動隊列管理演算法，顯式擁塞指示（ ecn ）改變了當前internet卜以丟包作為網路擁塞指示的方法，路山器通過預測早期的擁塞向源端提供顯式擁塞指示，饞避免了擁塞之後丟棄更多的數據包。
  8. Prepare printing process documents and updated them according to ecn

    編制印刷工藝文件，並根據ecn對工藝文件進行更新。
  9. Ecn explicit congestion notification

    顯示擁塞通告
  10. Ecn engineering change notice

    工程變更通知供貨商
  11. Ecn engineering change notes

    工程變更通知供應商
  12. Setting up and the use of boms bills of materials, product routing production models, ecn engineering change notes, etc.

    項目資料之維護技巧設定物料清單工序的處理及工程變動的使用
  13. Ecn emergency communications network

    應急通信網路
  14. Where possible procedures and measurements used by existing national monitoring schemes are employed so that ecn provides an integrating function for the more extensive sectorial networks

    在可能的情況下，應該應用現在國家或國際監控方案中的程序或測量標準，因而環境變化網路為更廣泛的區域網路提供綜合函數。
  15. Follow material ecn and reduce ecn obsolete cost

    跟進材料工程更改通知，減少因工程更改而導致的報廢。
  16. Poor ecn management. no filing, no record, no follow up

    極差工程變更管理，沒有存檔，沒有紀錄，沒有跟進
  17. To be responsible for ecn development, revision, issue, register

    負責工程修改通知單的起草，審批，發放，登記的工作。
  18. It is up to only engineering to decide for ecn. no systematic ecr feedback

    一般由工程部決定ecn ，沒有工程變更要求管理系統
