機制設計被越來越多地用於各種場合，包括設計無線電頻段拍賣機制、以及為防務合同設計更加合理的支付機制以克服成本加成合同（會產生消極怠工的激勵）或固定價格合同（會導致給價過高）的弊端。And the solutions of the three problems above are discussed : the solution to the simulcast interfering which is caused by the simulcast delay spread ( sds ) and the zero - beating is given in chapter four. based on the well understanding of the principle of ms - i / h / 0 in ipnp, the examples are given in chapter five on how to solve the problem of communication interruption between paging zones. through the analyse of signal switching between chengdu and deyang, the synchronization error between flex frames, and the bug in the multi - frequency roaming principle are pointed out
通過以上分析，文章探討了對上述三個問題的解決： ?對同播干擾問題，分別分析了時延差和零拍頻所造成同播干擾的客觀存在，探討了系統設計和網路優化的基本方法； ?對ipnp聯網障礙，提出了在掌握ipnp對各pncc作為輸入局歸屬局?輸出局（ ms ? i h o ）的靈活定義、以及相關參數配置原理的基礎上，分析聯網障礙的思路； ?對信號切換障礙，以成都和德陽兩地的局部廣域覆蓋為例，分析了flex幀失步和flex多頻漫遊原理設計缺陷的客觀存在，並探討了相關的解決方法和建議。The importan charateristics of wat902h camera and pci 500 camera and methods of capturing video are also included in this paper. imaging computer outside submarine can transfer data between control computer in the submarine by w2k ' s tednal service with highspeed. due to specific charaeristics of undersea optical imaging, underwater imaging processing technique fall into two categoriesfhardware and software, hardware are the design of the lenses used in waer and the choice of high - quality ccd caxner4the other is compllter digital irnage processing, that is mainly gray - level boformation and image sharpening. underwater image - processing software is designed on the basis of image processing on windows avi digital video file
由於水下光學成像的特殊性，水下圖象處理技術應該包括硬體和軟體兩個方面，硬體即水下專用成像鏡頭的設計與高性能的ccd選擇，後期圖象處理軟體是利用計算機數字圖像處理技術提高水下拍攝圖象的質量，處理方法主要有灰度變換和銳化處理；實現了對windowsavi數字視頻文件文件的圖像處理技術，並在此基礎上完成了水下電視系統圖像處理軟體的設計。After filtering out the part of low frequency from the data coming from condition monitor and calculating the comprehensive magnitude of spectrum around the clap - frequency, the alarm limit of clap - frequency vibration mal - functions are determined by using statistical method
從信號中濾除高頻成分，求得樣本拍頻附近譜線的綜合幅值，用數理統計的方法確定了拍振故障報警限。In this thesis a high precision frequency ( range ) estimation technique based on the phase of the fft of the beat - note signal is presented. the phase of the fft of the beat - note signal changes with the range between the radar and the liquid surface
差拍信號的fft幅度最大處的相位隨距離變化，因此可以利用fft相位在一個頻率（距離）分辨單元范圍內估計差拍信號的頻率（距離）的位置，從而提高頻率（距離）估計精度。Pickup cameras take in the video and get the data and translate to the computer. computer operates the avi video stream manipulation and the image processing
攝像頭拍攝被檢驗的儀表獲得視頻數據，計算機通過對avi文件視頻流的實時操作，對儀表進行實時的自動監控，實現監測儀表指針運動異常的功能。Image processing system is a very important part of mini unmanned helicopter, which mainly dealing with how to detect the object and supply the navigation computer with location information of the object. however, the varied background and the moving of the camera make the image processing become difficult. to solve these problems, this thesis introduces an object detection algorithm based on contour retrieving, template match and hu moments invariant
硬體組成詳細探討了系統結構，並對所採用的ccd攝像機、視頻採集卡等硬體單元作了描述；在軟體設計中，首先對不同操作系統環境下的視頻捕獲做了討論；接著，重點研究了針對機載攝像機拍攝圖像的目標檢測方法，提出並實現了基於模板匹配和不變矩的目標檢測演算法，以及基於機器學習的目標檢測演算法。分享友人
