3D Cadastre: With or Without Subsurface Utility Network?

Within the global trend of designing and implementing 3D cadastre, this paper offers a discussion about the integration of subsurface utility networks in such land tenure systems. Three questions are addressed: Do we need to register underground objects? Should underground networks be registered in the Land Register, with the same specifications...

Local velocity measurements in the shrek experiment at high reynolds number

We report preliminary results obtained using new local velocity probes in the Superfluid Helium high REynold number von Kármán flow (SHREK) experiment for different forcing conditions. The presentation will focus on the validation of the signals obtained from a hot-wire and a total head pressure tube in both normal and superfluid phases of...
