简介：这篇文章在端对端的交换子在异构的收音机存取技术(老鼠)之中为联合收音机资源管理(JRRM)作为一条自治途径介绍基因算法(GA)可计算的系统。联合会话承认控制(JOSAC)和带宽分配作为基因算法的操作与某些明智的修正做的一个特定的决定被联合。建议算法在下列二个条件上被触发。当一个会议被开始时，让会议在最适当的老鼠上宿营并且为需要的服务选择最合适的带宽被触发。当一个会议终止时，通过移交调整进行中的会议的分发也被用来。这将为最好的系统表演增加JRRM控制器的调整频率。模拟结果显示建议自治JRRM不仅有效地策划移交预定，而且完成很好的还原剂在光谱用途和堵住的概率之间的交易。

简介：作为为一张PC类型纤维接头结束脸的最重要的几何参数之一，顶偏移量能贡献高插入损失和高背思考读物。为参数的一个新奇测量方法，接头旋转--方法，被建议。与方法，一张普通接头结束脸的顶偏移量被测量。结果与由北国3000纤维接头结束脸干涉仪测量了那相比。二结果之间的差别是1.8m，这被发现。同时，顶上的相关错误资源的影响在旋转下面抵消测量--方法和顶核心方法分别地被分析，并且二个错误方程被导出。分析结果看那，与顶核心方法相比轴在以内并且在对它的旋转引起的主要飞机垂直的指示的二另外的亚tilts是否不比原来的轴大倾斜角度，最大。测量错误然后将被至少22.5%与旋转减少--方法。方法的有实行可能被实验证实。
