本文研究了由偶、奇相干态分别与真空态构成的叠加态光场的压缩效应.结果表明,在适当条件下,偶、奇相干态与真空态的叠加态场皆可存在二阶压缩和振幅N次方压缩,偶相干态与真空态的叠加还可使偶相干态原有的二阶压缩效应得到增强. 相似文献

文章在分析了分布式仿真中传统态势可视化系统的基础上,提出了一种通用态势可视化系统的设计。它是基于面向对象的态势对象模型,使用基于消息的松散耦合方式实现态势对象与仿真通信模块相关联.通过态势模型配置解决了态势可视化的可组织性,态势对象定制解决了态势可视化的可扩充性。从而实现了通用的态势可视化系统。最后通过实践给出了通用态势可视化系统的特性和优点。 相似文献

基于三个二粒子纠缠态作为量子信道,提出了一种类型的未知三粒子GHZ态或其正交态的概率克隆方案.该方案中,当量子信道是最大纠缠态时,通过普通的量子隐形传输过程, Bob(态的接收者)能够在其粒子上重建未知态.在Victor(态的制备者)的帮助下, Alice(态的发送方)可以一定的概率获得未知态或其正交态.随后的方案中,讨论了量子信道是非最大纠缠态时量子隐形传输的过程,在这种情况下, Bob可以一定的概率接收Alice想要传输的态,由于此过程也需要Alicc进行贝尔测量,所以在随后的克隆过程中, Alice在态的制备者的帮助下同样能以一定的概率获得未知态或其正交态. 相似文献

This paper presents the techniques of implicit traversing and state verification for sequential finite state machines(FSMs) based of on the state collapsing of state transition graph(STG). The problems of state designing are described. In order to achieve high state enumeration coverage, heuristic knowledge is proposed. 相似文献

Partitioned finite state machine (FSM) architectures in general enable low-power implementations and it has been shown that for these architectures, state memory based on both synchronous and asynchronous storage elements gives lower power consumption compared to their fully synchronous counterparts. In this paper we present state encoding techniques for a partitioned FSM architecture based on mixed synchronous/asynchronous state memory. The state memory, in this case, is composed of a synchronous local state memory and an asynchronous global state memory. The local state memory uses synchronous storage elements and is shared by all sub-FSMs. The global state memory operates asynchronously and is responsible for handling the interaction between sub-FSMs. Even though the partitioned FSM contains the asynchronous mechanism, its input/output behaviour is still cycle by cycle equivalent to the original monolithic synchronous FSM. In this paper, we discuss the low-power state encoding method for the implementation of partitioned FSM with mixed synchronous/asynchronous state memory. For the local state assignment a, what we call, state-bundling procedure is presented to enable states residing in different sub-FSMs to share the same state codes. Based on state-bundles, two state encoding techniques, in which one is the employment of binary encoding and the other is the further optimization for low power, are compared. 相似文献

The Label Distribution Protocol (LDP) needs to recover its state information after a control plane failure, so that the established connections in the data plane are not disrupted by any new connection set-up. We propose a backup mechanism to store the LDP state information in an upstream neighbour node. The backup LDP state information is synchronized with the original LDP state information in a downstream node when the LDP sets up or tears down connections. Then, we propose a two-step LDP state information recovery, which uses a fast LDP state information recovery to recover what labels are idle before a control plane failure, and a detailed LDP state information recovery to fully recover all LDP state information. The fast LDP state information recovery is realized as part of the LDP initialization, allowing a restarting LDP session to process new connection set-up requests as soon as possible, without interfering existing connections. The detailed LDP state information recovery performs in the background in parallel to the normal LDP operations. When an LDP connection teardown requires the LDP state information that has not yet been recovered, an on-demand query based LDP state information recovery is conducted. The performance analysis demonstrates that our proposal achieves fast LDP recovery for the core label state information. It features scalable LDP state information storage and recovery by only involving a pair of neighbour nodes. 相似文献
