简介：因为质地图象不能被单个象素的灰色的水平信息直接处理，我们建议反映在每个象素集中的补丁的紧张分发的一个新质地描述符。然后，Potts模型的一般多相的图象分割模型被增加质地描述符的区域信息为质地分割扩大。一个快数字计划基于裂口Bregman方法被设计加快计算过程。算法是有效的，并且质地描述符和典型函数能容易被实现。用合成质地图象，真实自然景色图象和合成的孔雷达图象的实验被介绍给在我们的方法和另外的最先进的技术之间的质的比较。结果证明我们的方法能精确地分割目标区域并且在分割自然图象特别与另外的方法相比是竞争的。

简介：photonic水晶的热性质有18个循环地分布式的核心的纤维(PCF)激光被使用完整向量的有限元素方法调查(女性)。结果证明18核心PCF与单个核心PCF和19核心PCF相比举办更有效的热分散建设。另外，有不同热负担的18核心PCF激光的温度分发被模仿。当热负担在近似对应于600W的抽的力量的80W/m上面时，结果证明核心温度接近近似拉1800K的价值的纤维，当当热负担在近似对应于110W的抽的力量的15W/m上面时，涂层温度接近大约550K的损坏价值时。因此冷却的纤维是必要的完成力量可伸缩。与另外的不同冷却系统相比，使计划凉下来的铜被发现是一个有效方法减少热效果。
