Unexpected shortage of water supply is common phenomena especially in dense population such as in hostels. Water supply at the students’ hostels is usually drawn from tank at the roof top of the building. Apparently there is no early warning system to monitor the tank water level when it has reached the critical level. The situation worsened when there is no personnel or technician in-charge to...

Human activity event recognition (HAER) within a residence is topic of significant interest in the field ambient assisted living (AAL). Commonly, various sensors are installed to enable monitoring people. This work presents new approach for HAER by (re-)using measurements from commercial smart water meters. Our based on assumption that changes flow residence, specifically transition no above ce...

A robust fault diagnosis and validation strategy for temperature sensors and ow meters in central chilling plant is developed, which is based on the rst law of thermodynamics. The strategy evaluates soft sensor faults (biases) by examining and minimizing the sum of the squares of concerned mass or steady state energy balance residuals represented by the corrected measurement over a period. It c...
