针对城市地下病害风险评估问题兼具模糊性和随机性，提出一种基于云理论和集对理论的城市地下病害风险评估模型，定量评估病害危险性。依据相关标准，从风险发生概率和风险后果两方面选取25项病害风险评估指标，建立4级风险评估体系及指标量化标准；引入不确定性人工智能中研究模糊性与随机性关联的云理论，利用基于2阶中心距和4阶中心矩的逆向高斯云算法将指标值转化为指标云模型；
利益相关者视角的地方政府融资平台风险管理研究
地方政府融资平台 利益相关者 风险 熵权-正负理想点评价模型
2019/4/19
通过构建熵权-正负理想点评价模型，采用五级分类法对选取的9家代表性地方政府融资平台公司进行风险评估，发现我国地方政府融资平台风险整体可控，但部分风险较高。基于利益相关者视角，剖析地方政府融资平台风险的生成原因与传导路径。为实现地方政府融资平台整体利益最大化，需要中央政府的主导与统筹以及利益相关者的共同配合，最终实现对地方政府融资平台风险的有效控制。
尼龙网方格沙障风沙流携沙粒度的空间分异特征
尼龙网方格沙障 风沙流 粒度空间分异
2018/4/18
为了探究塔克拉玛干沙漠腹地尼龙网方格沙障对风沙流携沙粒度的空间分异作用，于2015年4-6月，选取裸沙地和尼龙网2种下垫面，利用方口集沙仪和全方位集沙仪分别收集风沙流中垂直高度层中2~100 cm和16个方位的输沙量，利用BT-2001激光粒度分布仪对沙样进行粒度组成分析。结果表明：沙粒的粒度频率曲线形态表现为单峰分布特征，与下垫面沙粒组成有关。在垂直方向上，沙粒的平均粒径在L1（裸沙地）、L2（...

基于e次根攻击RSA的量子算法
信息安全 密码学 RSA密码 量子计算
2018/6/13
量子算法的出现给现有的公钥密码体制带来了严峻挑战，其中，最具威胁的是Shor算法。Shor算法能够在多项式时间内求解整数分解问题和离散对数问题，使得当前应用广泛的RSA、ElGamal和ECC等公钥密码体制在量子计算环境下不再安全，因此研究量子计算环境下的密码破译就有重大意义。解决整数分解问题是Shor算法攻击RSA的核心思想，但攻破RSA并非一定要从解决整数分解问题入手。作者试图从非整数分解角度...
