PLANE-BASED REGISTRATION OF SEVERAL THOUSAND LASER SCANS ON STANDARD HARDWARE
Terrestrial laser scanning registration plane-to-plane correspondences stochastic modelling large networks
2018/3/30
The automatic registration of terrestrial laser scans appears to be a solved problem in science as well as in practice. However, this assumption is questionable especially in the context of large proj...
3D VISUALISATIONS IN SIMULATIONS OF FUTURE LAND USE: EXPLORING THE POSSIBILITIES OF NEW, STANDARD VISUALISATION TOOLS
three-dimensional visualisations visualisation techniques Google Earth
2015/9/28
Three-dimensional visualisations are an interesting method for representing model outcomes. But most visualisation techniques
require expensive software, and a lot of time to create them. When a lar...
This letter proposes and experimentally demonstrates a cost-effective phase-modulation duobinary modulation scheme for improving self-phase modulation tolerance using a single modulator. Successful tr...

2011/5/15
We experimentally demonstrate 1-Tb/s CO-OFDM transmission over 1040-km standard single-mode fiber using 50% overhead girth-12 LDPC-coded 16-QAM. More than 4-dB improvement in OSNR sensitivity is achie...
Limitations for Applying Standard 10G Ethernet Sequence Order-Set in G.709 Core Transport Network
Fiber optics communications 060.4250 Networks
2010/6/5
Current lab assessment shows standard 10G Ethernet link fault sequence ordered-set works as expected between two direct attached clients. This paper evaluates the limitations applying the same ordered...
Recently revised ITU-T G.709 defines a container for 100 Gbps signals called an OTU4. This paper highlights some of the reasons the OTU4 bit rate, frame structure, and mapping scheme were chosen.
Silicon Lateral Avalanche Photodiodes Fabricated by Standard 0.18 μm CMOS Process
Avalanche Photodiodes Fabricated CMOS Process
2009/7/17
A Si APD was fabricated by standard 0.18 μ m CMOS process. The maximum avalanche gain was 224 for only 8 V bias. The bandwidth was 1.6 GHz for low avalanche gain and 800 MHz for large avalanche gain.
