简介：尽管这被显示出HHT的实现--如果运动的方程被使用而不是差别方程评估下一步加速，一个方法能在假动态测试导致改进错误繁殖性质，当过去常解决一个非线性的系统时，这篇论文证明这个方法可能导致不稳定性。，它的无条件的稳定性为非线性的系统仅仅为线性有弹性的系统被验证，因为集中的步度是不到1，不稳定性发生。集中罐头的步度经常在假动态测试是不到1，是值得注意的，自从仅仅当集中的步度不管它的价值是否更大接近1时，一个会聚的答案被完成或不到1。因此，到假动态测试的这个计划的申请应该被禁止，自从不稳定性的可能性可能不正确地破坏一个标本。因而，由使用差别方程决定下一步加速的HHT-α方法的实现在假动态测试为使用被推荐。

简介：那结果的消除是解决multivariate多项式方程的一个有效方法，是众所周知的。在这份报纸，而不是由可变消除经由变量计算目标resultants，作者联合multivariate含蓄的方程插值和multivariate计算减少的resultants的结果的消除，在哪个multivariate的技术含蓄的方程插值被一些高概率算法在multivariate多项式插值和univariate上完成合理函数插值。作为结果的消除的应用，作者在三个著名未解决的组合几何优化问题上说明建议算法。实验证明结果的消除的建议途径比某存在更有效这些困难的问题上的结果的消除方法。

简介：由对改进隔离表演的需要激发了，许多研究研究与非线性的特征在隔离乾上被执行了。基于他们的阶段肖像的形状，如此的设备能作为也被设置单稳态或双稳态的隔离乾。这篇论文集中于在一样的刺激下面调查这二个班的相对表演。力量能递送被用来测量隔离表演，它以播送力量的比率的RMS被定义到刺激力量。当系统受到泛音刺激时，在隔离的力量能递送的最大的减小用伪变化，这被发现--零僵硬被完成。当系统受到随机的刺激时，它有伪的一样的效果--零僵硬。进一步，最佳抑制能与僵硬被改变并且有最小的价值。
