To improve the accuracy of node trust evaluation in a distributed network, a trust model based on the experience of individuals is proposed, which establishes a new trust assessment system by introducing the experience factor and the comparative experience factor. the new evaluation system considers the differences between individuals and interactive histories between nodes, which solves the problem that nodes have inaccurate assessments due to the asymmetry of nodes to a certain extent. the algorithm analysis indicates that the new model uses different deviating values of tolerance evaluation for different individuals and uses different updating values embodying node individuation when updating feedback credibility of individuals, which evaluates the trust value more reasonably and more accurately. in addition, the proposed algorithm can be used in various trust models and has a good scalability
為了提高分散式網路中各節點信任評價的準確度,提出了一種基於個體經驗的信任模型.該模型通過引入經驗因子和相對經驗因子的方法,建立了新的信任評價體系.這種新的信任評價體系考慮了個體節點的差異問題,在計算節點的信任值時考慮了節點間的交互歷史,這在一定程度上解決了由於節點的非對稱性而導致的信任評價不準確的問題.演算法分析表明:新模型能夠針對不同的個體節點,採用不同的最大容忍評價偏差,並且對個體節點的反饋可信度進行更新時,採用不同的更新值,體現了節點的個性化特徵,使信任評價更加準確合理.此外,所提出的新演算法能夠運用到多種信任模型中,具有很好的可擴展性In collaboration with the department of physicis and material science of the city university of hong kong and the electronic and engineering department of the chinese university, the faculty of medicine has conducted research on different aspects of computer - aided navigation such as brain shift prediction with finite element model, three - dimensional ultrasound based correction for brain shift, accuracy verification, robotic system, surface identification and matching

結果表明: wilson方程和正規溶液模型對強正偏差體系比較適合,不適用於強負偏差體系和混合偏差體系。Then, this paper empirically tested the validation and predictive accuracy of different var risk management model in the domestic financial market. finally, with the analysis of modem financial risk management development trend and the current domestic financial risk management situation, this paper made a prospect for the application of this model in the construction of domestic financial risk management system. through the analysis, the main conclusions are as follows : ( l ) the traditional mean - variance model is the special example of the portfolio selection based on the var risk management model for the case that the returns of the portfolio are assumed to be normally distributed ; compared with the mean - variance model, the var risk management model is more comprehensive and accurate in the measurement of the portfolio risk, so based on the var model, the investors can allocate the asset more effectively. ( 2 ) the var risk management model can provide the timely and comprehensive risk information for the top risk manager, so it is very helpful to the improvement of total risk management efficiency. ( 3 ) based on the var model, the raroc performance valuation approach can reflect the real performance of the portfolio manager and provide the coherent standard for the allocation of risk limitation and the construction of the incentive compatibility constraint mechanism in the financial instiutions
通過研究分析,本文主要得出如下結論: ( 1 )傳統的markowitz均值? ?方差模型僅僅是在資產組合收益率正態分佈假設條件下基於var風險管理模型進行資產組合選擇的特例,與均值? ?方差模型中的方差風險度量方法相比, var風險管理模型能夠更全面、更貼切地衡量資產組合的風險,且基於此模型能夠更有效地進行資產配置決策; ( 2 ) var風險管理模型能夠滿足更高層次風險管理者對風險信息的需求,有助於整體風險管理效率的提高; ( 3 )基於var風險管理模型的raroc績效評價能夠反映資產組合管理人的真實業績,從而為金融機構風險限額的分配和激勵約束機制的制定提供統一的標準; ( 4 )國內證券市場資產組合收益率服從正態分佈的假設明顯不成立,實證檢驗表明基於資產組合收益率正態分佈假設條件下的方差? ?協方差模型對國內資產組合風險的預測存在較大的偏差,由於文中證明在收益率正態分佈假設條件下基於方差? ?協方差模型進行資產組合選擇的結果等價于markowitz的均值? ?方差模型,因此,均值? ?方差模型對國內資產組合風險的預測同樣會存在著較大的偏差,而半參數var風險管理模型則能夠取得較好的預測衡量效果; ( 5 ) var風險管理模型符合未來金融風險管理的發展趨勢,基於var風險管理模型建立內容提要風險限額內控體系、風險信息披露體系和業績評價體系,並進行金融監管,將有助於國內金融機構內部風險管理方法和外部監管技術跟上國際金融風險管理的發展潮流。There had no significant differences in the results of economic valuation of solid waste management in macao applying ce method and double - bounded cvm ; but ce method could reveal more preference information of consumers
結果表明,應用選擇試驗模型法和雙邊界二分式條件價值法得出的澳門固體廢物管理經濟價值結果相差不大,但選擇試驗模型法比雙邊界二分式條件價值法能更充分地揭示出消費者的偏好信息。The correlation study between level of psychological health, personality characteristics, parent upbringing matter and types of delinquency was conducted by using mmpi, mhs and embu as research tools in combination with such research methods as clinic interference and individual case tracing. the results of the research show, 1. psychological health condition of most delinquent teenagers is about average or below ( in grade one and grade two if classified from grade one to grade five ) 2
研究結果發現: 1 、罪錯青少年的心理健康狀況以中等偏低為主(按1 ? 5等級來劃分,處于第1 、 2等級) ; 2 、罪錯青少年mmpi整體人格分量表pd為72 . 04達到明顯病態,人格分量表ma 、 pa 、 pt 、 f偏高,與對照組相比有顯著性差異; 3 、罪錯青少年的心理健康水平與其罪錯類型有關系,且不同的罪錯類型被試心理機制各異; 4 、罪錯青少年的父母教養方式主要以拒絕否認型、溺愛型、消極型為主; 5 、通過臨床干預發現,改變罪錯青少年的父母教養方式、隔絕其與不良團伙的交往可以更快糾正其罪錯行為。As a new kind of piezoelectricity macromolecule material, pvdf ( polyvinylidene fluoride ) has not only lower density, but also better piezoelectricity, good mechanical performance and plasticity. when a particular shaped pvdf film is used as an error sensor and is bonded to the surface of the measured structure, there will be little effect on the system
由於pvdf ( polyvinylidenefluoride聚偏氟乙烯)是一種新型的壓電高分子材料,它不僅密度低,而且具有較強的壓電性,機械性、可塑性好等特點。用特定形狀的pvdf薄膜作為誤差傳感器,將它貼在結構體表面上時,對系統產生很小的影響。分享友人
