简介：recommender系统的众多的应用程序能提供我们理解用户的一个工具。组recommender反映多重用户行为的分析，并且试图向这个组的每个用户提供他们根据用户偏爱包含的事情。当前，大多数存在的组recommenders在用户之中忽略相互作用。在组活动期间，然而，交互偏爱将戏剧性地影响recommenders的成功。当用户的一些未知偏爱被另外的用户部分在这个组影响时，这个问题变得甚至更挑战性。能使用组活动历史信息和recommender的命名掌握(基于交互偏爱的组Recommender)被介绍的一个基于相互作用的方法产生交互偏爱参数的等级以后的反馈机制。评估建议方法的表演，它与在MovieLens数据集上的传统的合作过滤相比。结果关于有效性和精确性为多用户显示GRIPrecommender的优势。

简介：让是四元数海森堡组，并且让P是仿射的自守组。我们上经由P的单一的代表在四元数海森堡组上开发连续小浪变换的理论。光线的小浪的一个班被构造。反的小浪变换被使用光线的小浪简化。然后，我们上调查氡变换。一个Semyanistyi-Lizorkin空格被介绍，在哪个上氡变换是bijection。我们由欧几里德几何学的Fourier变换和组Fourier变换在两个上处理氡变换。这二个处理是实质上相等的。如果小浪是光滑的，我们也由使用小浪给一个倒置公式，它不要求功能的光滑。另外，我们获得上与亚拉普拉斯算符联系的氡变换的一个倒置公式。

简介：我们是否用声学的记载的工具测量阶段或组速度，仍然被说服。在这份报纸，三种模型被用来由理论分析和数字模拟调查这个问题。首先，我们使用与不同速度包含二个飞机波浪的飞机波浪重叠模型并且能改变阶段速度和组速度的价值。数字结果看那阶段速度是否比组速度更高或低，用缓慢时间连贯(STC)我们能仅仅给阶段速度的方法。根据分散分析和分支切割集成的结果，当组速度由到达时间拣获得了时，第二在僵硬边界地上凿穿为分散曲线的结果和STC方法获得的速度是阶段速度的一阶的模式表演的波形建模。最后，偶极子登录一个慢形成模型用分散分析和真实轴的集成被调查。分散曲线和完整的波浪火车的结果与僵硬边界条件作为地上凿穿模型显示出类似的结论。
