一种改进的Arnold Cat变换图像置乱算法
Arnold Cat变换 混沌映射 均匀置乱
2009/12/28
Arnold Cat变换是经典的图像置乱算法，但其存在密钥量小，置乱视觉效果差的缺点。同时置乱仅仅是重新排列图像各像素点的位置，像素值并没有发生改变，这样攻击者就可以通过统计分析等手段进行破译。针对Arnold Cat变换的不足，运用混沌理论，提出了一种基于均匀性的改进Arnold Cat变换置乱算法。仿真实验证明改进的算法具有密钥量大、置乱视觉效果好、图像的位置和像素值均发生本质改变等优点，增加...

创造力测量手段——同感评估技术（CAT）简介
同感评估技术 发散思维测验 领域特殊性 内隐观
2007/12/11
同感评估技术（consensusassessmenttechnique），又称主观评价法，是Amabile于1982年提出的评价创造力的一种方法。文章简要回顾了同感评估技术出现之前，基于发散思维测验的创造力评价法及其局限性。人们在寻求新的创造力评价方法的过程中，提出了同感评估技术。文章重点介绍了同感评估技术的理论基础，即它的同感定义和概念定义，然后说明了同感评估技术的具体使用方法、发展，以及在各领...
活性氧介导多种疾病发生的病理生理过程。细胞防御体系利用抗氧化酶如超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GPx)来对抗活性氧。SOD催化·分解产生H2O2，CAT和GPx则将H2O2分解为H2O和O2而彻底解毒，并避免·OH基团的产生。尽管长期以来人们希望将过氧化氢酶应用于防治各种氧化应激损伤，但由于其穿透细胞的能力不足因而限制了其在临床上的应用。为了使自胞外途径加入的...
