Experimental and digital characterisations of the hydro-mechanical behaviour of a heterogeneous powder/pellet bentonite material

The MX80 powder/pellets mixture is one of the candidate sealing plugs used in deep radioactive waste disposal because of its swelling properties and operational advantages (lower compaction effort, reduced gaps between the rock and the seal). The present work focuses on the microscopic scale of the material, which is studied using several...

BQC: A new multi-GNSS data quality checking toolkit

Multi-GNSS networks, for example M-GEX and iGMAS, are set up and grow quickly with the development of new navigation systems and multi-GNSS receivers. It is unavoidable that GNSS signals are deteriorated by several error sources. Thus GNSS network operators, data users and receiver designers all require data quality checking (QC). However, few...
