Detection of inter-turn faults in multi-phase ferrite-PM assisted synchronous reluctance machine [PDF]

open access: yes, 2019
Inter-turn winding faults in five-phase ferrite-permanent magnet-assisted synchronous reluctance motors (fPMa-SynRMs) can lead to catastrophic consequences if not detected in a timely manner, since they can quickly progress into more severe short-circuit

The use of cement leftovers from the hollow of spun piles as an additive in self-compacting concrete [PDF]

open access: yes, 2018
Spun piles have been used widely by developing countries, including Malaysia, to construct the foundation of most construction projects. A spun pile is a reinforced precast and prestressed concrete that is compacted in a mould through spinning compaction.
