By directed acyclic graph model, video server can select correct substreams by network bandwidth and terminal capability to get any frame rate, spatial resolution but coarse granular scalability presentation of video
通過該模型，視頻流媒體服務器能夠根據網路帶寬，終端能力，正確地選擇子碼流進行傳輸播放。 -
A file format is proposed based on the generic model and iso base media file format. we first create a directed acyclic graph model to describe the substreams and relationships among those substreams in a scalable video stream
本文首先建立了一個有向無環圖模型，該模型能夠描述可擴展視頻編碼碼流中各子碼流和子碼流間復雜的依賴關系。 -
Second, an adaptive rate - distortion model is proposed by extending directed acyclic graph model for fine granular scalable video coding. we add rate, original distortion and adaptive scale to the directed acyclic graph model
其次，針對精細粒度可擴展視頻編碼技術，本文擴展有向無環圖模型，在該模型中加入碼率，原始失真和自適應因子等屬性，建立了自適應率失真模型。 -
In this paper, we use directed - acyclic graph ( dag ) to represent a query processing, then define a cost model and a query efficiency model, and finally put forward an algorithm for materialized views selection
在考慮空間約束的基礎上，提出一種物化視圖選擇方法，並給出了切實可行的演算法步驟。 -
A belief network is a probability model defined on an acyclic directed graph ; distributed means nodes can be on different hosts, and heterogeneous means allowing different conditional distributions
一個信念網路是定義在一個非循環有向圖上的概率模型；分佈性指節點可以在不同的主機上，異質性指可以允許不同的條件分佈。
