基于时间Petri网的多媒体同步模型 总被引:1,自引:1,他引:1
多媒体同步是多媒体应用的一个重要需求,这已为众多研究人员所共识。多媒体同步的一个主要问题是多媒体同步时间需求的描述和建模。本文在克服当前多媒体同步模型局限性的基础上,提出了一个新的基于时间Petri网的多媒体同步模型--MSTP模型,它能使多媒体系统依据实际运行时的延迟和多媒体动脉同步类型。以更准确、高效的方式来保持多媒体同步。 相似文献

An Internetworking Function (IWF) carrying VBR voice traffic between N-ISDN and B-ISDN networks will be considered. Based on the way the partially filled cells problem is addressed, two techniques governing the operation of the IWF will be proposed. In the first technique, bit stuffing will be considered, while in the second, delaying these unfilled cells will be suggested. It is assumed that in both cases, speech silence detection is employed. As an evaluation measure, the bandwidth utilization, the cell loss, the percentage of stuffing, and the delay performance will be computed. Results will be then presented and analyzed, followed by conclusions and suggestions. 相似文献

In this paper a new presentation of the relational theory of queries will be given. Both the relational algebra and the (domain) relational calculus will be systematically derived from first-order logic. The connections between logic, algebra and calculus will become extremely simple: e.g. the relational algebra will be isomorphic with a subset of relational calculus. Also some theoretical results about the completeness of the relational query languages will be presented. Both the relational calculus and the relational algebra will be extended to contain aggregate functions. 相似文献

软件对环境的依赖性主要体现在软件与环境的交互。在实际中,有时软件与环境未必成功交互。其交互程度对软件的性能有着很大的影响。为测试不同软件在环境下的性能,需要对软件与环境的交互能力进行比较。在进程代数理论基础上,利用完整迹语义,建立软件近似程度的量化模型。形式化描述软件与环境的部分交互。列举一些例子对模型进行说明。建立软件近似程度的量化模型,证明一些代数性质。进一步,建立评价软件在与环境交互方面好坏的标准。 相似文献

信号灯是煤矿井下的交通指示灯,和地面上的交通红绿灯得功能一样,以保证机车能在煤矿井下的安全有秩序的运行。本文将应用图像识别技术对信号灯进行识别,首先,对井下采集上来的图像进行相应的处理,对信号灯的邻域进行分析,确定信号灯的特征,然后对其进行识别,最后输出信号灯的结果,其中结果为红灯还是绿灯。 相似文献

This paper presents a complete numerical formulation for the nonlinear structural analysis of prestressed membranes with immediate applications in Civil Engineering. The membranes will be considered to undergo large deformations but moderate strains. Therefore, Nonlinear Continuum Mechanics principles dealing with large deformations on prestressed bodies will be accounted for. The constitutive model adopted for the material will be a prestressed Saint Venant–Kirchhoff hyperelastic one. To carry out the computational resolution of the structural problem, the Finite Element Method (FEM) will be implemented according to a Total Lagrangian Formulation (TLF), by means of the Direct Core Congruential Formulation (DCCF). Different numerical schemes—first and second-order unconstrained optimization techniques—will be presented to solve the resulting geometrically nonlinear problem, which involves the minimization of the total potential energy system functional. These ones will be improved by a parametric line search algorithm according to a polynomial interpolation. Eventually, numerical examples will be introduced to verify the robustness of the aforementioned formulation. 相似文献

Over the next 10 years (2000-2010), a lot will happen in multiple technology areas (high-speed access to the home, high-speed applications, user-friendly applications, and security). We will see a huge increase in the demand for bandwidth, which will drive major changes to the high speed core of the network. Bandwidth will continue to grow rapidly. The rate of growth will average a factor of 4 per year over five years (implying total growth will be roughly a factor of 1000 relative to 1999 bandwidth). After that, growth might abate, but it will still be at least a factor of two every year through 2010. Optical switches with connection-oriented control planes will be used in the core because they provide very high bandwidth and density at a reasonable cost. Very large IP routers will, however, be necessary for statistical multiplexing and ubiquitous any-to-any connectivity. The core will therefore consist of multiterabit or petabit routers interconnected by very high density optical switches. As networks and bandwidths grow, it will become impossible for humans to do traffic engineering and to provision SLAs (service level agreements) 相似文献
