分析研究宏观审慎政策对银行稳定的实施效果及其作用机制,对于健全我国宏观审慎政策框架,完善系统性风险防范化解体系具有重要意义。利用2010-2022年中国16家A股上市商业银行的平衡面板数据,实证检验了宏观审慎政策与银行系统性风险之间的因果关系并分析其影响机制。实证研究结果表明:(1)我国的宏观审慎政策能够有效地降低银行系统性风险,经内生性检验和稳健性检验后该结论依然成立。(2)流动性类政策工具在降低银行系统性风险方面的效果最强,其次是资产类政策工具,最后是资本类政策工具。(3)银行的规模越小、资产经营的多元化程度越低、资产盈利能力越弱,宏观审慎政策在降低银行系统性风险方面的效果越强。(4)机制检验结果表明,宏观审慎政策通过减缓银行风险承担、削弱银行间互联性来降低银行系统性风险。最后从丰富和优化政策工具、以银行特征为依据的差异化监管、理顺政策作用路径等方面提出了相关建议。

反锐化掩膜(unsharp masking,USM)锐化是图像编辑中改善图像视觉清晰度的一种常用操作。然而,若将这一操作应用到篡改司法证据或者公共事件图片等场景,则会造成严重危害。近年来,图像取证领域的研究者已经提出许多USM锐化取证与反取证的方法,本文对该领域文献进行系统性综述。首先阐述USM锐化操作的基本原理,然后从算法实现原理角度对现有的USM锐化取证与反取证方法进行分类总结,接着介绍相关文献常用的数据集,并对现有方法的性能进行对比评价,最后分析现有方法面临的挑战并对未来的研究方向进行展望,主要包括以下几个方面:使用新的数据集,深入取证与反取证博弈的研究,深入研究锐化反取证,注重取证方案的执行效率,提高反取证的可靠性。

作者： shuang Xiang Bo Zhao An yang Tao Wei School of Computer Wuhan University

Infrastructure as a Service （laaS） has brought advantages to users because virtualization technology hides the details of the physical resources, but this leads to the problem of users being unable to perceive their security. This defect has obstructed cloud computing from wide-spread popularity and development. To solve this problem, a dynamic measurement protocol in laaS is presented in this paper. The protocol makes it possible for the user to get the real-time security status of the resources, thereby solving the problem of guaranteeing dynamic credibility. This changes the cloud service security provider from the operator to the users themselves. This study has verified the security of the protocol by means of Burrow-Abadi-Needham （BAN） logic, and the result shows that it can satisfy requirements for innovation, privacy, and integrity. Finally, based on different laaS platforms, this study has conducted a performance analysis to demonstrate that this protocol is reliable, secure, and efficient.

随着无人机和无人艇技术的迅速发展,无人机-无人艇协同应用逐渐成为未来海上军事任务和智慧交通的不可或缺组成部分。然而,考虑到无人艇在不同海况条件下的高动态特性,传统的雷达等手段虽然可以满足高精度和实时性的要求,但成本较高,而传统的视觉方法虽然成本低、易于实现,但稳定度较低。本文基于相机成像原理,提出一种无人机与无人艇的单目定距方法。通过对着陆区域的多个标志物进行识别定距后,对无人艇着陆区域平面进行拟合重构,从而获取无人机与无人艇的距离,标志物越多,算法失效的概率越低。搭建数值模拟器对算法进行了测试,研究了算法在无人艇大倾角摇晃下的精度和稳定性。结果显示,算法在无人艇摇晃的情况下可以得到较为准确的距离,所有工况计算出X,Y,Z方向上的平均相对误差分别为7.47%、6.48%和8.04%。
