A FRAMEWORK FOR RELIABLE THREE-DIMENSIONAL UNDERGROUND UTILITY MAPPING FOR URBAN PLANNING
Underground Utility Mapping 3D Mapping Urban Planning
2018/11/9
To optimise the use of limited available land, land-scarce cities such as Singapore are increasingly looking towards the underground in search of more space. A good understanding of what already exist...
HIERARCHICAL PATH PLANNING FOR WALKING (ALMOST) ANYWHERE
Path planning Clustering algorithms LiDAR Terrain mapping Graph theory Cost function, Walking Open data
2018/11/8
Computerized path planning, not constrained to transportation networks, may be useful in a range of settings, from search and rescue to archaeology. This paper develops a method for general path plann...

Optical Network Planning Rate-Tunable NRZ Transponders
2015/7/16
We present simple reach estimators for 5 to 15Gb/s NRZ channels in commonly deployed networks and assess the benefits of tunable data-rate in core optical networks through routing and resource allocat...
Network Planning,Control and Management Perspectives on Dynamic Networking
Network Planning Control Management Perspectives Dynamic Networking
2015/7/16
We motivate that network planning, service provisioning and restoration, as well as service manage-ment need to be investigated and aligned at large in order to realize dynamic networking.
Introduction of Confidence Levels for Transparent Network Planning
Introduction Confidence Levels Transparent Network Planning
2015/7/14
Confidence level on connection feasibilities is used to obtain Q-estimate margins when parameter uncertainties are considered. Adding such margins to the Q-estimate instead of fixed margins gives 22% ...
