简介：为软件开发基于一个新DIY概念，在当有限元素程序生成器(FEPG)提供发展的一个平台，叫的一个软件系统上依附的一种自动产生节目的技术编程序，通过哪个一个科学研究人员能为解决方案以一个更直接、方便的方法提交他的特殊physico数学的问题到系统。为由使用有限元素方法解决流动和热问题，稳定技术和部分步方法被采用克服主要由于统治传送对流引起的数字困难。几个基准问题作为例子在这份报纸被给说明用法和自动程序产生技术的优势，包括在一个盖驱动的洞的流动，在一根圆形的管子中的开始的流动，在一个方形的洞的自然传送对流，并且经过圆形的柱体的流动，等等。他们也作为算法的确认被给看。

简介：我们开发概括有条件的对称(GCS)途径为KdV类型方程解决Cauchy问题的维的减小的问题。我们描绘承认某些高顺序的GCS并且由一些例子显示出主要减小过程的这些方程。获得的减小不能在标准谎言途径的框架以内被导出。

简介：我们在场为嵌套问题的一个新算法。许多同等地，spaced点被放在一张表上，并且一片被移动到点之一并且由一个角度旋转了。点和旋转角度组成片的收拾行李的态度。我们建议一个新算法说出HAPE(启发式的算法基于最小的全部的势能的原则)发现片在有最低重心的最佳的收拾行李态度。另外，为多角形重叠测试的一种新技术被建议它避免no-fit-polygon(NFP)的费时间的计算。HAPE的详细实现被介绍，二个计算实验被描述。第一个实验基于一个真实工业问题并且第二在11个出版基准问题上。用一爬山(HC)寻找方法，建议算法与另外的出版答案比较表现很好。
