The topics in this thesis are analysing the drawbacks of current h . 323 videoconference systems and popular solutions of them , discussing the advantages of dynamic bit rate allocation model and its features . 5 sub - modules implement the model 该模型的实现是通过5个子模块( rtp连接建立模块、数据包接收模块、媒体播放模块、反馈信息分析模块和动态位速率调整模块)来完成。
The features of the dynamic bit rate allocation model are listed below : 1 . the existed dynamic bit rate allocation algorithms that only involved the situations of data loss ca n ' t meets the requirement of the videoconference system 作者的动态位速率调整模块具有以下特点: 1 )已有的动态速率调整算法只考虑了发生loss时进行速率调整,在一定程度上不能满足视频会议系统的实际需要。
The groves mechanism is improved and applied to solve the risk problem of ssc . fifthly , the allocation of ssc cooperation profit can be transfered into n - game . a comprehensive profit allocation model is given which combines nash negotiation model with modified shapley value 5 .造船供应链合作利益分配:将造船供应链合作利益分配问题归结为n人合作对策问题,将nash谈判集和改进的shapley值结合起来,提出了一个合作利益分配方案。
A model of regrouping enterprises assets was proposed based on a stochastic asset allocation model . the best decisions with maximal profit and minimal risk of regrouping were studied concerning the assets , debt , loan , annexion and purchase . finally , a case was simulated 在随机资产分配模型基础上,提出了资产重组模型,研究了在企业财富收益最大,重组过程风险最小条件下,资产、负债、借款、兼并收购的最优决策问题,并且进行了案例仿真工作
According to its characteristic ; based on the principles of actuality , impartiality , efficiency and sustainability , an initial allocation model of water rights is built , including construction of index system , confirmation of index weight and choice of allocation proportion ' s accounting method 针对这一特性,依据现状、公平、效率和可持续准则,建立了水权初始分配的系统模型,包括指标体系的系统构建、指标权重的系统确定和分配比例确定的系统方法。
We must improve the survival condition and production condition of western people step by step . in the view of government , macro - control to western water environment should be strengthened . we can set up the scientific , complete and flexible management mechanism by constructing the secondary marketable allocation model , improving mechanism of water price , making up the systematization management of water resource and by building valley management model 对国家来说,则应在西部开发过程中加强对西部水环境问题的宏观调控,改过去水资源的供给管理为需求管理,通过科学构建西部水资源的准市场化配置模式,完善供水价格机制,建立水资源的系统化管理,流域管理模式等,在西部建立起科学、完整、灵活的水资源管理机制。
In the paper , the integrated research of characters , objectives , models , principles , index system and affecting factors of trans - boundary water resource allocatio is done : ( 1 ) the research progress in the trans - boundary water allocation in the past 10 years is summed up , and then the new development tendencies related are concluded ; ( 2 ) the key issues and difficulties on transboundary water allocation are judged through the analysis on the characters of trans - boundary water resource in both aspects of the natures and the international laws ; ( 3 ) the water allocation models as the whole allocation , the project allocation and the integrated watershed planning allocation are systematically analyzed ; ( 4 ) the technical index system is brought forward , their affecting items are discussed , and the major index are defined based on the analysis of allocation principles of the trans - boundary water ; and ( 5 ) the relative suggestions for the allocation of trans - boundary water resources in china are put forward 摘要综合研究了跨境水资源分配的特点、目标、模式、原则、指标体系和影响等因素:对近10年来跨境水资源分配的研究进行了总结,归纳出新的发展趋势;从自然和国际法两方面属性分析跨境水资源的特点,判识跨境水分配的核心问题和难点;系统地分析了全局分配、项目分配和流域整体规划分配等分水模式;在分析跨境水资源的分配原则基础上,提出了分水技术指标体系,并探讨了其影响因数和主要指标的确定;结合这些研究,对我国的跨境水资源分配,提出了相关建议。
In regards to techniques employed in active asset allocation , the author found that models applied in asset allocation can be divided into the optimal mean - variance model and risk averse asset allocation model , according to their different risk levels , and they can also be divided into linear asset allocation model and non - linear asset allocation model according to whether the asset return follows a normal distribution 关于积极资产配置的技术,作者研究结论认为,积极资产配置模型按对风险的不同测度标准可区分为,均值方差最优化框架下的资产配置模型和下偏风险厌恶框架下的资产配置模型两类;按是否假定资产收益服从正态分布,可区分为线性资产配置模型和非线性资产配置模型。
Based on the research of videoconference systems of h . 323 protocol over ip networks and the author ' s experiences of implementing h . 323 videoconference systems in remote education area , in this thesis the main factors that affect videoconference quality are analyzed , and a dynamic bit rate allocation model is proposed and partly implemented . this model is designed to dynamically allocate bit rate for multi - media data flow ( including audio data and video data ) in fixed bandwidth network environment . when continuous multi - media packet losses are detected in ip based h . 323 videoconference system , the bit rate of video data is adjusted meanwhile the bit rate of audio data remains unchanged , and the bit rate allocation of multi - media data ( including audio data and video data ) is optimized as a whole effect 本文结合作者在h . 323视频会议系统应用于远程教育的经验,通过对现有的基于ip网络的h . 323协议视频会议系统的研究,分析了影响视频会议质量的原因,提出并部分实现了在固定带宽的网络环境下,基于ip的h . 323视频会议的多媒体数据包发生丢包、抖动或延时时,保持音频数据位速率不变,通过对视频数据的位速率的进行调整,最终实现旨在提高视频会议语音质量的多媒体数据位速率动态调整的模型。
The paper also studies the model ' s use in real r & d team , and give a solution on how to decide the team ' s assignments . innovation of this paper lies in following three points . first , trying to solve the long - term incentive problem based on eva ; second , establishing a new incentive allocation model through developing holmstrom model ; lastly , giving a solution to deciding the assignments of r & d team 本文创新之处有以下三点: 1 、运用eva来解决研发团队长期激励问题,并给出了具体的eva奖金计算公式; 2 、改进了holmstrom模型,据以建立“二次分配”的基本模型; 3 、探索了研发团队产出定额一种确定方式? ?奖惩框架下的业绩申报制度
