单幅Bayer格式图像的快速去雾方法

为了降低雾天对成像的影响,获得实时的去雾效果,对彩色图像处理流程进行改进,提出一种新颖快速的基于Bayer图像和暗原色先验模型的单幅图像去雾方法。Bayer图像是数码相机采集的原始图像数据,数据量小。针对Bayer图像像素排列特点,对原有暗原色先验去雾算法进行了优化和改进。运用四叉树细分算法估算大气光,根据Bayer图像特点修正了Guided Filter,并利用修正的滤波器优化大气透射图,进而恢复出无雾Bayer图像,采用去马赛克及系列后处理算法获得清晰的显示图像。实验结果表明,新方法在一定程度上改善了原算法去雾效果,并显著提高了运算速度。

孔子“仁礼合一”视域下的军事哲学思想探析

面对春秋时期礼崩乐坏之时弊,孔子以"仁礼合一"的儒家哲学视野,审视战争和军事问题,同时"仁礼合一"说亦为其构建军事思想的哲学价值根基。在现实社会领域,孔子展开一系列与之相适应的军事践履。其军事哲学思想与军事践履彰显了孔子追求和平的价值取向和精神自觉,体现了其对人的生命之价值与意义的深切关怀和对礼乐文明的守望与践履。     

折叠舵间隙非线性颤振分析研究

针对折叠舵的气动弹性问题,考虑三维翼型的非定常气动力,研究了弯曲和扭转两维间隙非线性颤振分析方法.时域仿真结果表明:间隙非线性环节将导致系统出现极限环振荡;频率散布的下限值决定亚临界颤振速度,频率散布的上限值决定发散速度;模态振型节线的方向同样影响亚临界颤振速度和发散速度.

On the Road to the 2015 NPT Review Conference

The second session of the Preparatory Committee for the 2015 Review Conference (RevCon) of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) highlighted two issues in particular—progress toward a Middle East Weapons of Mass Destruction–Free Zone and the Joint Statement on the humanitarian impact of nuclear weapons—that may not only greatly affect the health and vitality of the NPT and the 2015 RevCon, but possibly also have implications for the international nonproliferation regime as a whole. Dr. William Potter, director of the James Martin Center for Nonproliferation Studies, interviewed Ambassador Cornel Feruta, chairman of the 2013 PrepCom, to discuss these and other issues related to the meeting and the future of the treaty and its review process.     

One size does not fit all: personalized incentives in military compensation

A critical element in implementing a compensation scheme including nonmonetary incentives (NMIs) is recognizing that preferences vary widely across Service members. There are at least three sources of variability: across different population classes, across individuals within a population class, and across NMI packages for a particular individual. Surveys across different military communities, ranks, and years of Service show the difficulty of identifying any NMI that has significant value for even 50% of the active duty force. At the same time, approximately 80% of the surveyed Service members expressed a significant positive value for at least one NMI. Therefore, one-size-fits-all incentive packages will not be nearly as effective as more personalized incentive packages. The authors discuss variability in Service member NMI preferences and outline an approach to implementing personalized NMI packages in military compensation through a sealed-bid reverse auction, where Service members select individual NMIs from a “cafeteria-style” menu of options.
