An improved interactive dynamic multimedia synchronization model ( idsm ) based on tpn is proposed . the new model takes the dynamic synchronization properties and the demands of the priority of key medium and the function of user interaction in the distributed systems into account , introduces the allowed blocking time , backtracking rules and so on to handle the problems caused by random delay , blocking or lost packets , and describes the temporal behavior of multimedia information stream fully , accurately and formally . 4 提出了一個新的基于tpn網的交互式多媒體動態同步模型idsm ,該模型充分考慮到分布式環境中多媒體的動態同步特性以及關鍵媒體的優先權和人機交互要求,通過引入容許阻塞時間、回溯算法等有效克服了網絡隨機延遲、阻塞和丟包等因素的影響,以形式化的方式完整、準確地描述了多媒體信息流的時間行為。

Therefore , from this background , this thesis discusses the modeling power of time petri net , gives an example which explains that time petri net has the function of “ zero examination “ ; presents a method of transforming a timed petri net to a time petri net . then , two necessary and sufficient conditions , defining classes of tpns which have the same boundedness and liveness behaviors as the corresponding classical petri nets , are presented in this thesis 所以本文就從這個背景出發,討論了tpn的模擬能力,并給出了tpn能進行“零檢驗”的一個例子,給出了另一種含時間因素的時延petri網向tpn的轉換方法,給出了保持活性、有界性的兩個時間區間上的充分必要條件,最后,給出了保持活性的結構上和動態上的兩個充分條件。

Then a biped motion coordination control model based on timed petri - net ( tpn ) is built . simulation results of matlab show that the motion control model and the hominine gait pattern proposed above can automatically adapt to the changeful environments , it also shows the feasibility and superiority of petri - net method in solving this kind of problems 隨后建立其雙腿協調運動賦時petri網( tpn )模型,在matlab環境下的仿真結果表明提出的運動控制模型能夠自適應多變的外界環境,并證明了用pn方法解決該類問題具有可行性。

Because of its compactness , fineness and unambiguity , formal analysis of cryptographic protocol has been an efficient and correct method step by step . the dissertation mainly discusses using formal methods for analysis and evaluation of cryptographic protocols based on timed petri nets ( tpn ) 形式化分析由于其精煉、簡潔和無二義性逐步成為分析密碼協議的一條可靠和準確的途徑,但是密碼協議的形式化分析研究目前還不夠深入,本文主要研究了基于時延petri網的密碼協議分析和評估方法。

The time petri nets which are discussed in this thesis are very simple and have the same modeling power as the turing machine , however , in general , there is just no comparison between the liveness , boundedness behaviors of a given time petri net and those of its corresponding classical petri net without time restrictions 本文研究的timepetrinet (簡稱為tpn )簡單且模擬能力等價于圖靈機,但tpn的活性、有界性和對應的傳統petri網的相應性質并無對應關系。

The tpn model based on the extended temporal relationships set is described . furthermore , it is proved that every synchronization relationship among multimedia objects can be denoted with the tpn model . 3 給出了建于多媒體系統時態關系擴展集基礎之上的tpn網模型描述,證明了任意多個媒體對象之間的同步關系均可以用tpn網模型來表達。

Next , to gain accurate los rate is the key for hit - to - kill since true proportional navigation ( tpn ) is convergent if the initial state between ekv and target is inside the capture region 其次,由于真比例導引本身是穩定的,所以獲取一定測量精度的視線角速率是實現成功攔截的關鍵。

Objective to investigate the effects of total enteral nutrition ( ten ) vs . total parenteral nutrition ( tpn ) on protein metabolism , t - lymphocyte subsets and immune function of patient with major injuries 目的觀察創傷后早期腸內和腸外營養對機體免疫和代謝功能的影響。

( 2 ) the author introduces a new way to describe cryptographic protocol based on timed petri net , meanwhile , the concrete steps using tpn is expounded ( 2 )首次提出用時延petri網作為工具來分析和評估密碼協議,并且給出了用它分析和評估密碼協議的具體方法和步驟。
