博弈论在打假中的运用

运用博弈论的方法对个人打假、政府打假及举报制度进行假设、建模和分析 ,结果显示 :无论在个人打假中 ,还是在政府打假中 ,单纯依靠经济手段显然无法达到预期效果 ,而应该同时运用行政手段、法律手段、精神手段等 ,同时为了减少信息不对称对打假者的影响 ,有必要建立举报制度 .我们期望我们的分析结果能为有效开展打假活动提供一种思路 .     

经济代理人的最优损失控制

根据经济代理人对风险的厌恶程度高低将影响收益效用的事实,通过对经济代理人的风险厌恶系数引进阀值,使风险厌恶系数在不同取值区间对应不同的效用函数,对经济代理人具有常值绝对风险厌恶的效用函数,损失服从泊松分布、且保险市场被垄断的承保人控制的最优防损活动进行了研究.研究表明,风险厌恶系数、损失的大小以及防损效率将影响最优防损...     

Photoacoustic microscopy image resolution enhancement via directional total variation regularization

Photoacoustic microscopy(PAM) is recognized as a powerful tool for various microcirculation system studies. To improve the spatial resolution for the PAM images, the requirements of the system will always be increased correspondingly. Without additional cost of the system, we address the problem of improving the resolution of PAM images by integrating a deconvolution model with a directional total variation regularization. Additionally, we present a primal-dual-based algorithm to solve the associated optimization problem efficiently. Results from both test images and some PAM images studies validate the effectiveness of the proposed method in enhancing the spatial resolution. We expect the proposed technique to be an alternative resolution enhancement tool for some important biomedical applications.
