指狀分叉
英文
digitation-
The feathers attached to the arms and the tail evidently possess the structures of " modern feathers ", which consisting of the central shafts ( rachis ) and parallel barbs. dromaeosaurids are unusual group of maniraptoran theropods. they share many similar or the same features with archaeopteryx or other primitive birds, such as : u - shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and " modern feathers " with rachis and barbs etc. these facts indicate not only that dromaeosaurids had developed many bird - like characters in course of the advanced maniraptorans toward birds, but also that there seemed to be the co - evolutionary trend between the feathers and the skeletal bones
奔龍類是一類較為特殊的手盜龍類（ maniraptora ） ，它具有許多與始祖鳥archaeopteryx甚至其它早期鳥類相似或接近的特徵，主要表現在：叉骨u形與始祖鳥和孔子鳥類的相同，背肋鉤狀突在孔子鳥類和個別反鳥類中也存在，肩臼窩絕大部分指向側方類似於始祖鳥，肩胛骨與烏喙骨間的夾角非常接近90也和始祖鳥的相似，前肢從比例上講顯得較長，大的半月形腕骨使肘部能向側方折過來，恥骨伸向後下方，距骨上升突與原始鳥類中的為同源結構，羽毛已有顯著的分化且具備了現代羽毛的基本結構等等。The traffic organization optimization methods of turning - vehicle flows at at - grade intersections, include its advantages, disadvantages, available conditions and application notices, are chosen as research object in the paper
第三章對交叉口內左轉車流和右轉車流的交通組織方法分別進行了歸納和分析，並且對國內外的研究現狀進行了總結，指出一些組織方法在使用的注意事項。For the real time performance need of the low speed speech compress algorithm and the asic implement of the transfer process between programs, the design is put forward in the paper, in which state registers control the cross access between operator and memory, register windows are used for the parameters transfer, and the technique of hardware controlling is used to avoid pipeline conflict, so that the main problems of the transfer process in tr600 are solved effectively
摘要針對低速率語音壓縮演算法對處理器系統實時處理復雜運算的性能要求，就程序調用過程的asic實現問題進行了對比與分析，進而提出了用層次狀態寄存器控制存取運算元對存儲體交叉訪問的方法，並結合運用寄存器窗口傳遞參數的功能，以及利用空指令硬布線處理流水線沖突的方法，有效地解決了tr600晶元中調用過程存在的主要問題。In this dissertation, the research trends for the problem have been introduced ; the ‘ dim ’ and ‘ point ’ has been strictly defined in mathematics from machine vision and human vision ; the ideal clutter suppression system based on clutter predication and the realization and evaluation of evaluation index has been studied, in succession the clutter suppression technologies have been researched. firstly, the classic nonparametric algorithm has been analyzed in detail and systematically, for it ’ s weakness that it cannot remove the non - stationary clutter ideally, kalman filter algorithm for clutter suppression in 2d image signal has been built. secondly, fast adaptive kalman filter is presented based on fast wide - sense stationary areas partition algorithm : limited combination and division algorithm based on quarti - tree algorithm, new taxis filter route algorithm which can break through the limitation of the necessity of pixel neighborhood of 2d filter and laplace data model with two parameters which is perfectly suitable for the residual image of kalman clutter suppression
首先分析了經典的非參數法，對於四種具有代表性的核，從前述的三個性能評價方面做了分析和對比，指出了其速度快的優點和對非平穩圖像適應性差的弱點，針對非參數法的弱點，重點研究了對非平穩圖像適應良好的卡爾曼雜波抑制技術:建立了非平穩圖像的類自回歸模型，在此基礎上建立了二維卡爾曼濾波基礎的兩個方程:狀態方程和測量方程;建立了非平穩圖像準平穩區域快速劃分演算法:基於四叉樹法的有限分裂合併演算法;二維空間的基於k排序的濾波路線演算法，突破了空域濾波路線上區域相鄰的限制;在這些研究的基礎上實現了快速卡爾曼估計，實驗驗證了該方法相對逐點卡爾曼估計可以提高運算速度三倍左右;雜波抑制結果表明傳統的高斯性檢驗並不適合卡爾曼估計后的殘余圖像，由此建立了殘余圖像的雙參數拉普拉斯模型，實驗表明其可以完好的吻合殘余圖像的概率密度曲線。The hardware design is expounded in chapter 3, which include four parts. then we focus on how to merge them together in chapter 4, that is, porting linux to mc9328mx1, this includes several parts, the first part is flashloader which can be used to download programs ; and then, give out develop model of start - up guide code ( bootloader ) which runs before linux kernel and linux kernel ' s start - up analysis, also porting them to arm9 mx1 ; thirdly, we realizes the porting of lcd framebuffer driver based on deeply grasped linux device driver model ; fourthly, the rootfs ( file system ) ? ? cramfs is designed. then we give an example that based on the embedded linux in chapter 5, what we call automobile navigation, and discuss how to develop with our arm linux to meet the need of application, too
