Live In-Service Modification of Optical Network Elements Implemented with Xilinx FPGAs
Xilinx FPGA Optical Network Elements Service Modification
2015/5/18
This paper demonstrates that Xilinx FPGA partial reconfiguration technology can yield resource and power savings in optical network elements through selective hardware modification during live operati...
Nonlinear Tolerance of 112-Gb/s DP-QPSK in a Live Field Upgrade Trial over a 848km 10G DWDM Link
Live Field Upgrade 10G DWDM Link Nonlinear Tolerance DP-QPSK
2015/5/18
An in-service field trial with coherently detected DP-QPSK at 112 Gb/s was performed over a Telefónica live link of 848km, testing long term stability and determining noise margin and optimum launch p...
40 Gb/s upgrade of a 1614 km link over TrueWave-RS fibre with live 10G OOK traffic
TrueWave-RS 10G OOK traffic
2015/5/18
1614km link over TrueWave-RS fibre carrying 10G live traffic was successfully upgraded to 40Gb/s. XPM affecting 40G channels is simulated and experimentally measured for different channel powers and c...
Intra-Channel Chromatic Dispersion Measurements with Live Neighboring Signals in a Long Haul DWDM System
Optical communications Networks wavelength routing Fiber measurement
2015/6/5
A novel four-tone probe signal is used to measure end-to-end residual chromatic dispersion in single 50-GHz DWDM channels of a long-haul ROADM network while transmitting more than 30 live signals in n...
改进的live-wire交互式胸片图像分割
医学图像分割 胸片图像 live-wire算法 Gabor奇部滤波器
2011/4/19
肺部轮廓提取是计算机辅助诊断(computer-aided detection，CAD)的关键之一，并且能为医生提供可靠的诊断数据。提出了一种交互式肺部分割方法，用优化的Gabor奇滤波器对胸片图像进行滤波得到边缘响应能量图，然后用此边缘响应能量值来构造Livewire代价函数进行肺部分割。实验表明该算法能正确区分强弱边缘,快速有效地提取出肺部轮廓，与传统算法相比，能减少人机交互次数，更具鲁棒性...
Functional Study of Live Cells by Laser Trapping Technique
Numerical aperture Exocytosis Evanescent wave microscopy
2009/6/12
We tested a hypothesis that water ejection takes place in the secretory cell. A micro bead was held at about 1μm distant from the cell surface by laser trapping with a 1064 nm light, and the position ...
