简介：在这篇论文，我们在场一个不连续的Galerkin(DG)方法基于为解决在3-dimensional上从一个magnetohydrodynamics模型产生的一个第四顺序的卷屈方程的Nedelec有限元素空间围住Lipschitz多面体。我们证明方法为包含一个第四顺序的卷屈操作员的一个模型问题有最佳的错误估计。而且，在2种尺寸的一些数字结果被介绍验证理论结果。

简介：半含蓄的算法流行地被用来在数字模型处理重力的术语。在这份报纸，我们采用特征的方法在一个浅水模型用一个semi-Lagrangian移流计划直接在一个范围上为严肃波浪计算答案而不是半含蓄的方法，到避免昂贵的矩阵倒置。semi-Lagrangian计划的采纳为任何报纸数字使数字模型变为总是稳定，并且它节省中央处理器时间。为了说明特征的效率，抑制了插值侧面(CIP)方法，一些数字结果在Yin-Yang格子系统在一个范围上为理想化的测试用例被显示出。关键词特征CIP方法-浅水的模型-Yin-Yang格子-semi-Lagrangian计划-严肃波浪

简介：分离余弦变换压缩了的块想象，是众所周知的视觉上愤怒在low-bit-rate堵住人工制品的展览。分块的新processing以后在小浪领域的算法被建议。算法利用在小浪领域显示出的块人工制品特征。堵住人工制品的精力被集中进一些行在小浪变换以后形成讨厌的视觉效果。减少堵住人工制品的目的是有效地在块边界上捕获过多的精力并且在视觉范围下面减少它。为不同subbands的适应操作员基于小浪系数被计算。操作符被使适应到堵住人工制品的不同图象和特征。试验性的结果证明建议方法罐头显著地改进视觉质量并且也在产量图象增加山峰signal-noise-ratio(PSNR)。
