军工网络安全模拟仿真系统可信度研究

军工网络安全模拟仿真系统是一个多层次、多方面、多步骤的仿真系统。通过对系统进行VV＆A分析,结合层次分析法（AHP）的决策思想,把与仿真可信度有关的评估元素通过划分层次后并计算权重,建立起一种复杂仿真系统可信度评估的综合算法模型,最终得到整个军工网络安全模拟仿真系统的可信度。根据所得到的量化可信度结果,证明该系统具有一定的科学性。     

EASE软件声学参量模拟可信度的探讨

长久以来,人们对声学模拟软件EASE（无论版本高低）预测的一些室内声学参量数据结果都深信不疑,并以此为依据．致使在某些厅堂扩声系统工程招标中,将其作为工程设计标书中一个不可或缺的设计要求。笔者多年来对EASE软件不同版本及不同运算模块研究结果表明,上述观点在认识上存在很大的局限性。为了更深入认识和理解该软件．本文以EASE不同运算模块对同一厅堂声学参量运算结果进行对比、分析和讨论,得出EASE软件中只有AURA运算模块才能真正适用于厅堂扩声系统非扩散声场环境下的声学模拟。

You protest too much, methinks: Investigating the features of truthful and fabricated reports of traumatic experiences.

Legal decision-makers frequently assess the credibility of reports of traumatic victimization. In this study, we compared the memory features and post-traumatic symptoms associated with truthful and malingered reports of trauma. Participants (N=126) described in writing both a genuine and a fabricated traumatic experience (counterbalanced) and completed scales relating to the severity of the associated trauma symptoms. Relative to accounts of genuine trauma, the information in fabricated accounts was less plausible and contained fewer contextual details. However, truthful and false reports were qualitatively similar on other criteria such as coherence and relevance. Fabricated traumatic experiences were associated with extreme ratings on multiple, diverse psychological measures of emotional distress and a higher level of apparent post-traumatic stress disorder. However, most participants were able to "fool" widely used validity scales. Implications for evaluating the credibility of claims of victimization in legal cases are discussed.

Credibility protection for resource sharing and collaborating in non-center network computing environments

Non-center network computing environments have some unique characteristics, such as instability, heterogeneity, autonomy, distribution and openness, which bring serious issues of security and reliability. This article proposes a brand-new credibility protection mechanism for resource sharing and collaboration in non-center network computing environments. First, the three-dimensional hierarchical classified topology （3DHCT） is proposed, which provides a basic framework for realizations of the identity credibility, the behavior credibility and the capability credibility. Next, the agent technology is utilized to construct the credibility protection model. This article also proposes a new comprehensive credibility evaluation algorithm with simple, efficient, quantitative and able to meet the requirements of evaluating behavior credibility and the capability credibility evaluation as well. The Dempster-Shafer theory of evidence and the combination rule are used to achieve the evaluation of the capability credibility. The behavior credibility is evaluated with the current and historical performance of nodes for providers and consumers to realize more accurate prediction. Based on the non-center network computing simulation test platform, simulation is been conducted to test the performance and validity of the proposed algorithms. Experiment and analysis show that the proposed algorithms are suitable for large-scale, dynamic network computing environments, and able to maintain the credibility for networks without relying on central node, make a non-center network gradually evolve into an orderly, stable and reliable computing environment efficiently.
