简介:由于新兴的3D集成技术,芯片(MPSoCs)上的多处理机系统现在能与改进精力效率在芯片上集成更多的IP核心。然而,几严重挑战也升起在上面为3DIC由于死叠建筑学。在他们之中,电源供应噪音成为一颗大担心。在纸,我们调查电源供应噪音(PSN)在PSN变化大部分取决于的不同核心和级和表演之中的相互作用任务任务。在另一方面,高集成密度在3DIC上招致一个严重热问题。在纸,我们建议就PSN和热问题而言安排框架的一项新奇任务。它主要由三部分组成。首先,我们提取由分析他们踪迹从建筑学水平模拟导出的电源运用任务的当前的刺激。第二,我们开发一个有效电源交货网络(PDN)解答者高效地评估PSN大小。第三,我们建议一个启发式的算法解决安排问题的提出的任务。与最先进的任务任务算法相比,建议方法能在2上在12%减少PSN吗??
简介:摘要目的介绍一种实用、高效的后腹腔镜下D-J管放置方法。方法采用小儿导尿管管芯替换输尿管导管作为D-J管内支架管改良“双支架管技术”放置D-J管;即将小儿导尿管(8F或10F)管芯作为导丝,自D-J管侧孔分别插入D-J管的膀胱端和肾盂端,自输尿管切口将D-J管置入输尿管内,远端进入膀胱腔内,近端达肾盂,再拔除管芯。结果行后腹腔镜下输尿管切开取石手术30例,术中均采用“双支架管技术”改良法放置D-J管,均一次性成功.术后复查腹平片示D-J管位置无异常,拔除D-J管1个月后复查患肾积液情况及肾功能等均较术前好转。结论改良后的“双支架管技术”所用导丝取材方便、经济,操作实用、置管耗时短、成功率高,值得临床推广应用。
