The categories are not tidy and clearly defined : some synchronization mechanisms have characteristics of multiple categories ; events that release a single thread at a time are functionally like locks ; the release of any lock can be thought of as a signal ; and interlocked operations can be used to construct locks 上述类别的定义并非是绝对的:有些同步机制具有多个类别的特征;一次释放一个线程的事件的功能类似于锁定;任何锁定的释放都可看作一个信号;而联锁操作可用于构造锁定。
The design of the net - subsystem , the accomplish of the protocol stack and the design of streaming medias synchronization mechanism . these parts are so important that can influence the quality of our media player ’ s work , so i go into details these parts in this paper , the main content is below 对流媒体播放器而言,网络子系统结构设计、流媒体相关协议栈的实现与媒体流同步设计又是其中重中之重,它们决定着流媒体播放器的播放质量与效果,因此文中着重对这些内容详细分析,总体而言包括以下几部分内容。
Future directions on the pads domain are proposed which include research on the existed pads modeling defects to find out realistic method accommodating the pads synchronization mechanisms and compatible general software design patterns based on software engineering and research on operatable pads performance model helping modelers to predict the pads performance at a accepted cost before implementation . mrm ( multi - resolution modeling ) is becoming more important as large complex distributed simulations are carried out inside and out of military simulation community 提出了pads以后研究的方向:结合软件工程的方法,研究现有pads建模的上的缺陷,探寻既容纳pads仿真同步机制又兼容于普通软件设计方法的可操作的实用方法,减少pads系统设计和实现的额外开销和复杂性;研究包含pads性能实际影响因素的解析性性能模型和工具,使得用户在并行仿真实现之前能以相对较小的开销较为准确地预测pads系统的性能。
This thesis focuses on the research of the data replication and data synchronization technologies which are used in some of the commercial mobile database systems and experimental mobile database system prototypes . based on these research works , we propose an evolutionary data synchronization mechanism which uses union - transaction result set as its granularity of synchronization 本文重点研究了目前商用移动数据库系统和一些移动数据库系统原型中采用的复制和同步技术,并在此基础上提出了一种以关联事务结果集为同步粒度的同步机制。
This thesis analyzed and researched the theories of these mechanisms , and applied them to the project , expatiated the importance of these mechanisms . the main contributions of the thesis are as follows : 1 . based on the research of the synchronization mechanisms of the streaming media system and the time axis model , one model was implemented with rtp / rtcp standardization files ( rfc1889 ) as guidelines 作者在参与数字有机体流媒体系统研发工作中,主要取得以下研究成果: 1 .深入研究流媒体系统同步机制,针对rtp / rtcp协议提供的同步机制,实现基于时间轴模型的同步算法,并将该算法应用于流媒体服务器和网络终端组件。
Second , the paper establishes the dynamic model of dfh - 4 satellite with in which the deployment synchronization mechanism and deployment driving mechanism included using adams and also makes dynamics simulation of the deployment of the large - scale solar panels based on the established system dynamic model 其次,本文基于adams详细的建立了包含同步展开机构和展开驱动机构的dfh - 4卫星系统的动力学模型,并基于adams利用建立的卫星系统动力学模型对卫星太阳翼展开过程进行了详细的动力学仿真研究。
Because network game is built on the current internet , latency and transmission error in the network is unavoidable . as a result , more attention should be paid to the synchronization mechanism of game world state , and the study of it in network game engine is of great importance 由于网络游戏依托于现有的互联网技术,网络传输中的延迟、出错等问题总是不可避免的,故游戏中状态的同步便是一个很大的问题,因而网络游戏引擎中同步技术的研究对实际应用有很重要的意义。
